Answer:

22 stickers in each box

Step-by-step explanation:

Ling Ling = 587 stickers

Jia = 245 stickers

Therefore, total number of stickers = 587 + 245 = 832

if they gave 40 stickers to their cousin, then

remaining stickers = 832 - 40 = 792

If they put the remaining 792 stickers equally into 36 boxes, then

number of stickers in each box = 792 ÷ 36 = 22

In the given origami of the two dimensional figure , the value of angle 2 is 70° and the value of angle 1 is 110 °

Parallel lines are straight lines that do not intersect at any point in geometry.

Parallel planes are three-dimensional pathways that never intersect. Parallel curves do not touch or intersect and have a fixed minimum distance.

From the figure we can see that m∠1 = 4x-30 as they are vertically opposite angles.

Again m∠1 = 3x+5 as they are corresponding angles from the pair of parallel lines.

now let us solve the linear equation to calculate the value of x.

3x+5 = 4x-30

or, -x = -35

or, x = 35

Now

m∠1 = 3x+5 = 110

Therefore m∠2 = 180 -110 = 70 ( straight angle formed whose sum is 180)

Step-by-step explanation:

The mean SAT score is \(\mu=600\), we are going to call it \mu since it's the "true" mean

The standard deviation (we are going to call it \(\sigma\)) is

\(\sigma=48\)

Next they draw a random sample of n=70 students, and they got a mean score (denoted by \(\bar x\)) of \(\bar x=613\)

The test then boils down to the question if the score of 613 obtained by the students in the sample is statistically bigger that the "true" mean of 600.

- So the Null Hypothesis \(H_0:\bar x \geq \mu\)

- The alternative would be then the opposite \(H_0:\bar x < \mu\)

The test statistic for this type of test takes the form

\(t=\frac{| \mu -\bar x |} {\sigma/\sqrt{n}}\)

and this test statistic follows a normal distribution. This last part is quite important because it will tell us where to look for the critical value. The problem ask for a 0.05 significance level. Looking at the normal distribution table, the critical value that leaves .05% in the upper tail is 1.645.

With this we can then replace the values in the test statistic and compare it to the critical value of 1.645.

\(t=\frac{| \mu -\bar x |} {\sigma/\sqrt{n}}\\\\= \frac{| 600-613 |}{48/\sqrt(70}}\\\\= \frac{| 13 |}{48/8.367}\\\\= \frac{| 13 |}{5.737}\\\\=2.266\\\)

Answer:

The null hypothesis is that the SAT score is not significantly different for the course graduates.

Alternate hypothesis: there is a significant difference between the SAT score achieved by the course graduates as compared to the non-graduates.

Apply the t-test. The Test Statistic value comes out to be t = 1.738 and the p-value = 0.0844

Since the p-value is larger than 0.05, the evidence is weak and we fail to reject eh null hypothesis.

The first and second equations satisfy standard form of the linear equation, hence they are linear. While, third, fourth, and fifth are non linear equations.

A group of two or more simultaneous solutions to linear equations is referred to as a system of linear equations. A collection of values that satisfy every equation in a system of linear equations is the solution. There might not be a unique solution if the number of equations in the system is less than or equal to the number of variables in the system. Systems of linear equations can be solved using various methods, such as substitution, elimination, or matrix algebra.

The standard form of linear equation is given as:

y = mx + b

The first and second equations satisfy, or represent the standard form of the linear equation, hence they are linear.

While, third, fourth, and fifth do not represent the standard form and hence are non linear equations.

What is linear function?

In mathematics, a linear function is a type of function that can be represented by a straight line on a graph.

1.The equation m = 5.45p represents a linear function. It has the form y = mx + b, where m is the slope and b is the y-intercept. In this case, m = 5.45, which is a constant rate of change, and there is no other term involving p, so the equation is linear. When p increases or decreases by 1 unit, m increases or decreases by 5.45 units, respectively.

2.The equation 1=56.01+5 is not a function. It is a simple linear equation in one variable, but it has no independent variable to define a function. It is just an equation that states a relationship between two constants, 56.01 and 5, which sum up to 61.01.

3.The function d = (g-28)7/11 is a linear function because it can be written in the form y = mx + b, where m and b are constants and y and x are variables.

In this case, if we let d = y and g = x, we get:

y = (x-28)7/11

This can be simplified as:

y = 7/11 * x - 196/11

So we can see that the function has a constant slope of 7/11, and a constant intercept of -196/11. Therefore, it is a linear function.

4. This is a non-linear function since it includes a variable raised to a power (r³).

5.The function e=124² is a non-linear function as it involves squaring the value of 124, which produces a curved graph instead of a straight line.

Based on the information we can infer that the equation shown in the image is 1.23 - 0.35 = 0.88 (option B).

To identify the correct equation we must look at the graph and identify the information it provides. In this case we have two squares divided into 100 squares each. Additionally, the square on the left has 88 squares painted in red and 12 squares with an X inside. In the case of the square on the right, it has 23 squares colored in red with an X inside.

In total we have 123 squares painted in red, which in decimal number is equivalent to 1.23. On the other hand, the number of squares painted red and with an X inside is 35, this value would be 0.35.

On the other hand, the squares painted only in red are 88, so the equivalent in decimal numbers would be 0.88. Therefore, the correct way to express this relationship through an equation would be:

Step-by-step explanation:

By adding 1.5 and 0.3 we can see that the worker has 1.8 lbs. Converted to a fraction, this is 1 4/5. This can be multiplied by 3/3 to reach 1 and 12/15. He needs 3 and 10/15. By doing this we can see that the worker needs 1 and 13/15 lbs.

The instantaneous rate of change of y = √x at x = 2 is √2 / 2.

To find the instantaneous rate of change of y = √x at x = 2, we need to calculate the derivative of the function with respect to x and evaluate it at x = 2.

Taking the derivative of y = √x using the power rule for differentiation, we have:

dy/dx = (1/2) × x^(-1/2)

Now, substituting x = 2 into the derivative expression:

dy/dx = (1/2) × 2^(-1/2)

= (1/2) × √2

= √2 / 2

Therefore, the instantaneous rate of change of y = √x at x = 2 is √2 / 2.

Answer:

a) -|x+4|

b) |x-1| -6

Step-by-step explanation:

First, we can compare the functions to f(x)

For (a), the graph seems to be

- flipped upside down

- moved to the left by 4 units (we can tell this because the x intercept is at -4 instead of 0)

First, -f(x) turns a function upside down. Therefore, we have -f(x) = -|x| (this is our new f(x) for (a)).  Then, f(x+b) shifts a function b units to the left, so we have f(x+4) = -|x+4|. Note that the 4 is inside the absolute values as it is f(x+b) and not f(x) + b. For f(x+b), we substitute x+b for x. For f(x)+b, we add a b at the end.

For (b), the graph seems to be

- moved to the right by 1 unit (the turning point in the slope is at x=1)

- moved down 6 units (the turning point in the slope is at y=-6)

First, f(x-b) shifts the function b units to the right, so we have f(x-1) = |x-1|

Then, f(x) - b shifts the function b units down, so we have f(x) - 6 = |x-1|-6

d) The results of the ANOVA test may not be reliable.

(a) The hypotheses for this study would be:

Null hypothesis (\(H_0\)): There is no difference in the average lifetime of the four types of batteries.

Alternative hypothesis (\(H_1\)): There is a difference in the average lifetime of the four types of batteries.

(b) The completed ANOVA summary table would be:

Sum of Squares (SS) df Mean Squares (MS) F

Between (Factor) 25.7375 3 8.578 3.77

Within (Error) 75 56 1.34

Total 100 59

(c) To find the p-value, you would use the Fcdf function on your calculator. The syntax for this would be Fcdf(F, 10000, df Between, df Within). In this case, the F value is 3.77, the df Between is 3, and the df Within is 56. Plugging these values into the calculator would give a p-value of approximately 0.03.

(d) Based on the p-value, we can reject the null hypothesis and conclude that there is a significant difference in the average lifetime of the four types of batteries. This suggests that the type of battery has an effect on its lifetime. However, it is important to note that this conclusion is based on the assumptions of the ANOVA test, including the assumption of equal variances among the groups. If these assumptions are not met, the results of the ANOVA test may not be reliable.

The bank reconciliation reveals various errors and discrepancies between ABC Company's records and the bank statement, including missing deposits, incorrect check charges, outstanding checks, unrecorded interest proceeds, fees, NSF charges, and recording errors.

Upon analyzing the bank reconciliation for ABC Company, several discrepancies between the company's records and the bank statement are identified:

A deposit of Br. 410.90 made after banking hours does not appear on the bank statement. This indicates that the deposit was not processed by the bank before the statement was generated.

A check drawn for Br. 79 was charged by the bank as Br. 973. This suggests an error by the bank in processing the check, resulting in an incorrect charge to ABC Company.

Outstanding checks are checks issued in July but have not yet been paid by the bank. The checks include check numbers 801, 888, 890, and 891, with respective amounts of Br. 100.00, Br. 10.25, Br. 294.50, and Br. 205.00.

A check written for Br. 210 was charged by the bank as Br. 120, indicating an error in the bank's recording.

The proceeds from the collection of an interest-bearing note receivable from David, with a face amount of Br. 500, are not reflected in the bank statement.

A Br. 24.75 interest earned on the average account balance during July is included in the bank statement.

A check for Br. 10, which was recorded in the check register as Br. 100, was returned with the statement. This discrepancy could be due to an error in recording the check amount.

A Br. 5.00 fee was charged by the bank for handling the collection of a note receivable.

A Br. 50.25 check from customer John, deposited by ABC Company, was charged by the bank as Non-Sufficient Funds (NSF), indicating that the customer's check bounced.

A Br. 12.70 service charge was imposed by the bank for the month of July.

Answer:

There are six possible outcomes when rolling a die, each of which is equally likely. Of these six outcomes, three are greater than 2 (3, 4, 5) and three are not (1, 2, 6). Therefore, the odds in favor of rolling a number greater than 2 are 3 to 3, or simply 1 to 1. Alternatively, we could express this as a probability: the probability of rolling a number greater than 2 is 3/6, or 1/2, since there are three favorable outcomes out of a total of six possible outcomes.

Step-by-step explanation:

We can set up an equation based on his monthly savings to find out how long it will take for Hatif to reach $630 in his account.

Let's assume it takes Hatif "n" months to reach $630 in his account. Each month, he saves $80.

The equation representing the situation is:

$150 + $80n = $630

Now, let's solve for "n":

$80n = $630 - $150

$80n = $480

n = $480 / $80

n = 6

Therefore, it will take Hatif 6 months to reach $630 in his account.
