Assume that each circle shown below represent one unit express the shaded amount as a single fraction and as a mixed number

Step-by-step explanation:

remember a few things :

a × -1 = -a

-a × -1 = a

-1 × -1 = 1

1 × a = a

therefore,

-1 × -1 × a = 1 × a = a

and finally

c × (a + b) = c×a + c×b

so, we can say

(1 - 5) = -1 × -1 × (1 - 5) =

= -1 × (-1×1 + -1×-5) = -1 × (-1 + 5) =

= -1 × (5 - 1) = -(5 - 1)

a. Null says equal weight across 4 coves and Alternative says at least 1 is different b. image attached c. reject Null hypothesis d. Proportion of variation = (S3/3) / (S3/3 + 6) = S3 / (S3 + 18)

a. Null hypothesis: The mean weight of dolphins in the Gulf of Mexico is equal across all four coves (cove A, B, C, and D).

Alternative hypothesis: The mean weight of dolphins in the Gulf of Mexico differs across at least one of the four coves.

b. Using the partial ANOVA table, we can fill in the missing values:

The filled table is attached as an image.

c. Based on the ANOVA table, we can reject the null hypothesis (p < 0.05) and conclude that there is a significant difference in the mean weight of dolphins across at least one of the four coves. However, we cannot determine which specific cove or coves have different mean weights without further analysis.

d. The "Between Coves" row in the ANOVA table represents the variation in dolphin weights that can be attributed to the differences among the four coves. The "Total" row represents the total variation in dolphin weights. The proportion of the total variation accounted for by location is the ratio of the sum of squares between coves to the total sum of squares:

Proportion of variation = (S3/3) / (S3/3 + 6) = S3 / (S3 + 18)

Without the value of S3, we cannot calculate the proportion of variation. However, we can say that if the F-ratio is large and the p-value is small, then a larger proportion of the variation in dolphin weights is accounted for by location.

Answer:

By using the energy conservation law, the input energy must be equivalent to the output energy.  If you measured output energy is lower than your input energy, you have lost that difference of energy either in mechanical inefficiency (friction, heat, etc.) or an energy sink.

Thus, the energy not output by the machine is lost in the process within the machine.

To find out how much the computer shop earned on average per day, we need to divide the total earnings by the number of days that the shop was open. In this case, the shop was open for 48 hours straight, which is equivalent to 2 days (since there are 24 hours in a day).

So, the average earnings per day can be found by dividing the total earnings of 96,000 by the number of days, which is 2:

Average earnings per day = 96,000 ÷ 2 = 48,000

Therefore, the computer shop earned an average of 48,000 per day over the weekend. To represent this as a simplified fraction, we can write:

48,000/1 = 48,000/1, which can be simplified to 48,000/1, or just 48,000. So, the shop earned 48,000 on average per day, which is equivalent to the fraction 48,000/1.

If an environmentalist group wishes to measure the amount of dissolved oxygen per liter of water in a local stream, then the detailed solution is down below.

A dataset's variability is quantified by its standard deviation. It is determined by taking the square root of the variance, which is the sum of the squared deviations between each value in the dataset and its mean. How far a dataset's individual values deviate from its mean is determined by its standard deviation. A low standard deviation suggests that the dataset's values are close to the mean, whereas a large standard deviation suggests that the dataset's values are widely dispersed. When comparing the spread of two or more datasets, standard deviation is frequently utilised. It is a widely used statistical measure of dispersion.

How to solve?

a. The point estimate for the average amount of dissolved oxygen is 4.62 mg.

b. The distribution to use to construct the confidence interval is student-t.

c. Provide the values A - E for this problem on the following graph.

A. The sample mean is 4.62 mg.

B. The sample standard deviation is 0.92 mg.

C. The degrees of freedom for the student-t distribution is 45 - 1 = 44.

D. The t-value for a 90% confidence interval with 44 degrees of freedom is 1.699.

E. The error bound or margin of error is 0.92 mg * 1.699 = 1.57 mg.

d. The Confidence Interval is (4.62 - 1.57, 4.62 + 1.57) = (3.05, 6.19) mg, which means the error bound (or margin of error) is 1.57 mg.

e. The interpretation of this interval is that the environmentalists are confident that the true amount of dissolved oxygen in the stream is between 3.05 mg and 6.19 mg.

Answer:

Step-by-step explanation:

The slope-intercept form of a linear equation is y = mx + b, where m is the slope (the rate of change) and b is the y-intercept (the point where the line crosses the y-axis).

To write this equation, we need to know the y-intercept and the slope.

The y-intercept is the initial amount of money in the savings account, which is $300.

The slope is the amount of money added to the savings account each month, which is $25.

So the equation in slope-intercept form is:

y = $25x + $300

This equation shows that for every month that goes by, Hallie's savings account will increase by $25 and the starting point is $300

Using Euler's approach, the error in the estimated value of y(0.25) is approximately 0.09375 or 0.094.

Given the ODE and initial condition as:

dy/dx = (1+2x)√y, y(0) = 1

Using Euler's method, we have to evaluate the value of y(0.25) with a step size of h = 0.25.

Step 1: Calculation of f(x,y)f(x, y) = dy/dx = (1+2x)√y

Step 2: Calculation of y(0.25)

Using Euler's method, we can approximate the value of y at x=0.25 as follows:y1 = y0 + hf(x0, y0)where y0 = 1, x0 = 0 and h = 0.25f(x0, y0) = f(0, 1) = (1+2(0))√1 = 1y1 = 1 + 0.25(1) = 1.25

Therefore, y(0.25) = 1.25.

Step 3: Calculation of the exact value of y(0.25)We can find the exact value of y(0.25) by solving the ODE:

dy/dx = (1+2x)√ydy/√y = (1+2x) dxIntegrating both sides:

∫dy/√y = ∫(1+2x)dx2√y = x^2 + 2x + C, where C is athe constant of integration Since y(0) = 1,

we can solve for C as follows: 2√1 = 0^2 + 2(0) + C => C = 2

Therefore, the exact solution of the ODE is given by:2√y = x^2 + 2x + 2Solving for y, we get:y = [(x^2 + 2x + 2)/2]^2

The exact value of y(0.25) is given by:y(0.25) = [(0.25^2 + 2(0.25) + 2)/2]^2= (2.3125/2)^2= 1.15625

Step 4: Calculation of the errorError = |Exact value - Approximate value|Error = |1.15625 - 1.25| = 0.09375

Therefore, the error in the approximate value of y(0.25) using Euler's method is 0.09375 or 0.094 (approx).

Answer:

The Answer is Question 3

Step-by-step explanation:

A statistical question is something that could be graphed in a histogram or table, such as colors or sports different kids like. A non-statistical question results in just one answer, such as what one person's favorite color is. It cannot be compared to other data as there is no other data.

In Question 1 it is asking what each person in our class had. This is collecting data from different sources (students) and it will not result in just one answer. It is asking about multiple people. Therefore, question 1 is statistical.

In Question 2 it is also asking what multiple kids ate. Therefore question 2 is statistical as well.

In Question 3 it is only asking what Maria is having for lunch. It could not be compared to others or put in a histogram or table because we do not know what any other kids ate. Therefore, question 3 is not statistical.

Question 4 is also referring to multiple people, so question 4 is statistical.

Question 3 is non-statistical.

\(\Huge\boxed{x=53}\)

Step-by-step explanation:

Hello There!

Once again we need to use trigonometry to solve for X

Here are the Trigonometric Ratios:

Sin = Opposite divided by hypotenuse

Cos = adjacent divided by hypotenuse

Tan = Opposite divided by adjacent

We are given the adjacent side of x (45) and the hypotenuse (75) so we need to use cos

Remember cos = adjacent divided by hypotenuse

Now we create an equation

\(cos(x)=\frac{45}{75}\\\frac{45}{75} =.6\)

now we have

\(cos(x)=.6\)

like always we want to get rid of cos

to do so we take the inverse of cos (arccos^-1) and apply that to each side

\(arccos^-^1(cos(x))=x\\arccos^-^1(.6)=53.13010235\)

finally we round to the nearest degree

we're left with x = 53
