Answer:

problem 1 is 70 and problem 3 is 100

Answer:

B

Step-by-step explanation:

Anna can buy a maximum of 7 snacks with $35.

To determine how many snacks Anna can buy, we can set up an inequality based on the amount of money she has. Let's denote the number of snacks as x.

The cost of a ticket is $9.50, and each snack costs $3.50. Anna's total spending should be less than or equal to $35, which can be represented by the inequality:

9.50 + 3.50x ≤ 35

In this inequality, 9.50 represents the cost of the ticket, 3.50x represents the cost of x snacks, and 35 represents the total amount of money Anna has to spend.

To find the maximum number of snacks Anna can buy, we need to solve the inequality for x. Here's how we can do that:

Subtract 9.50 from both sides of the inequality:

3.50x ≤ 35 - 9.50

3.50x ≤ 25.50

Divide both sides of the inequality by 3.50:

x ≤ 25.50 / 3.50

Calculating the division:

x ≤ 7.2857

Since we can't have a fraction of a snack, we round down to the nearest whole number:

x ≤ 7

Therefore, Anna can buy a maximum of 7 snacks with $35.

Answer: 0.29

Step-by-step explanation:

OQ is the side opposite angle P, QP is the side opposite angle O, and PO is the side opposite angle Q.

This means that tangent = opposite/adjacent, the tangent of angle O is the opposite side, QP, over the length of the adjacent side, OQ. (It cannot be PO since that's the hypotenuse)

This means that the tangent of O is 7/24, which is about 0.29

Answer:

D. 1,248 cubic units

Step-by-step explanation:

the volume of the rectangular prism = length*width*height = 12*8*13 = 1248 cubic units

Answer: D. 1,248 cubic units

Step-by-step explanation:

The formula for a rectangular prism volume is: V = Length x Width x Height.

In this question it already gives us all of the sides that we need! So all we need to do is just multiply all the sides together to get the volume.

12 x 8 x 13 = 1,248. Therefore D is correct!

(a) The vector belongs to the row space of A and is nontrivial since it is not the zero vector.

(b) A is a 3-by-3 matrix and the basis for the nullspace has only 2 vectors, the rank of A is 3 (the maximum possible rank for a 3-by-3 matrix).

(c)  A is invertible.

a. To find a nontrivial vector in the row space of A, we can take the transpose of the basis for the nullspace. Since the nullspace basis is given as {[1 0 5], [1 1 2]}, the nontrivial vector in the row space would be obtained by transposing one of these vectors. Let's choose the first vector [1 0 5] and take its transpose: [1, 0, 5]. This vector belongs to the row space of A and is nontrivial since it is not the zero vector.

b. The rank of a matrix is defined as the maximum number of linearly independent rows or columns. Since A is a 3-by-3 matrix and the basis for the nullspace has only 2 vectors, the rank of A is 3 (the maximum possible rank for a 3-by-3 matrix).

c. A matrix is invertible if and only if its rank is equal to its number of columns. In this case, since the rank of A is 3 and the number of columns is also 3, the rank condition for invertibility is satisfied. Therefore, A is invertible.

Yes, the P-value is the probability, assuming H0 is true, of observing a value for the test statistic that is as extreme as or more extreme than the value actually observed.

The p-value is the probability of obtaining a statistic that is more or more extreme than that observed in experiment.

The p-value is calculated assuming the null hypothesis is true. Therefore, the lower the p-value, the stronger the evidence that the null hypothesis is false. That is, the lower the p-value, the stronger the evidence in favor of the alternative hypothesis.

The P-value is the observed test statistic (i.e., the data summary) that is as extreme as or more extreme than the currently observed test statistic under a statistical model that specifically assumes that the hypothesis is being tested. is the probability that It's true.

Step-by-step explanation:

The expression is -45.32 + 41.11, and so you are basically just doing 45.32-41.11, but the answer will be negative.

45.32-41.11=4.21, but the answer is negative, so -4.21.

The proportion of color-blind women would be 4%  as each individual has two alleles.

In a population where mating is random and red-green colorblindness does not affect survival or fertility, the proportion of color-blind women can be calculated based on the Hardy-Weinberg equilibrium (HWE) equation.

If 8% of the men are color-blind, the proportion of color-blind women in the population would be 1.6% (or 0.016).

According to the Hardy-Weinberg equilibrium, in a population with random mating, the frequencies of alleles and genotypes remain constant from generation to generation in the absence of evolutionary forces.

The equation for the HWE is p² + 2pq + q² = 1, where p represents the frequency of the dominant allele (non-colorblind) and q represents the frequency of the recessive allele (colorblind).

In this case, if 8% of the men are color-blind, it means q² = 0.08. Solving for q, we take the square root of 0.08, which is approximately 0.2828.

Since q represents the frequency of colorblind individuals (men and women combined), and women have two alleles, the frequency of color-blind women (q²) would be (0.2828)² = 0.08 (or 8%).

Converting this to proportion, the proportion of color-blind women would be 0.08/2 = 0.04 (or 4%), as each individual has two alleles.

Answer:

= 9/10

Step-by-step explanation:

- × - = +

Then:

2×1/5 = (2×1)/5 = 2/5 = 12/30

-(-3×1/6) = +(3*1)/6 = 3/6 = 15/30

Then:

2×1/5-(-3×1/6) = 2/5 + 3/6 = 12/30 + 15/30 = (12+15)/30 = 27/30

27/30 = 9/10

Answer:

Step-by-step explanation:

Answer:

We can start by multiplying the first equation by 3:

12x + 24y = 120

Then we can multiply the second equation by 4:

12x - 8y = 56

Now, we have:

12x + 24y = 120

12x - 8y = 56

If we subtract the first equation from the second equation:

32y = 64

y = 64/24

y = 2

Now that we know the value of y, we can substitute it back into one of the original equations to find the value of x.

Let's use the first equation:

4x+8(2) = 40

4x+16 = 40

4x = 24

x = 24/4

x =6

So, the solution of the system of equations is x = 6, y = 2.

Answer:

x=1

y=3

Step-by-step explanation:

x+y=4

2y-4x=2

x=4-y

2y-4(4-y)=2

2y-16+4y=2

6y=18

y=3

x=4-3

x =1

To answer this question, we can use the standard normal distribution to find the probability for x > 120. We can proceed as follows:

1. We need to find the z-score for the given raw value of 120.

2. We know that the z-score is given by:

Where

• x is the raw value (x = 120).

• μ is the population's mean. In this case, μ = 109.

• σ is the population standard deviation. In this case, σ = 11.

Therefore, we have that the z-score is:

We can see that the value for z = 1. It means that the value is one standard deviation above the mean of the population.

If we use a cumulative standard normal distribution table, and we find the value for z = 1, we will have a cumulative probability of:

However, we are looking for P(z > 1). Therefore, to find this value, we can proceed as follows:

Therefore:

We need to remember that this value of z is a "transformation" of the value 120 into the standard normal distribution.

In summary, we can say that:
