Which are examples of unit rates?

2 answers:

Answers: Choice A and Choice C

Saying "$45 per ticket" is the same as saying "$45 for every single ticket" or "one ticket costs $45"

Similarly, "30 seats for every row" is equivalent to "each row has 30 seats"

-------------

choices B and D aren't unit rates because the second value mentioned isn't 1. You would have to divide to get to a unit rate.
choice B: 5/3 = 1.67 so there are roughly 1.67 shows every week
choice D: 100/5 = 20 meaning its $20 per ticket

Answer:

The answer is " $(-33.9218,-16.0782)\\\\$ ".

Step-by-step explanation:

Calculating the critical value:

Freedom Degree= 7.

The significance level, $\alpha= 0.05$

Using excel function the critical value:

$\to t_{\frac{\alpha}{2} (df)}=t_{\frac{0.05}{2},7}\\\\=T.INV.2T(0.05,7)\\\\=\pm 2.3646\\\\$

When $95\%$ of the confidence intervals for the difference of means:

$\to (\bar{x_1}-\bar{x_2}) \pm t_{\frac{\alpha}{2}}\sqrt{\frac{S_1^2}{n_1}+\frac{S_2^2}{n_2}}\\\\=(90-115) \pm 2.3646 \sqrt{\frac{5^2}{8}+\frac{102^2}{9}}\\\\=-25 \pm 2.3646 (3.773077)\\\\=(-33.9218,-16.0782)\\\\$

What is the value of?<br> –4<br> –2<br> 2<br> 4

Oliga [24]

Answer:

2 is your answer.

Step-by-step explanation:

Simplify. Remember to follow PEMDAS. First solve the parenthesis, then multiply, and finally divide.

-8(17 - 12) = -8(5) = -40

-2(8 - (-2)) = -2(8 + 2) = -2(10) = -20

-40/-20 = 2

2 is your answer.

The point (-7,4) is reflected over the line x=-3. Then the resulting point is reflected over the line y=x. Where is the point lo

Ne4ueva [31]

Answer:

(4, 1)

Step-by-step explanation:

Since the first reflection is over the vertical line x=-3, the y-coordinate remains the same. The x-coordinate of A' will make the point (-3, 4) on the line of reflection be the midpoint between A and A':

(-3, 4) = (A +A')/2

2(-3, 4) -A = A' = (-6-(-7), 8 -4) = (1, 4)

The reflection over the line y=x simply interchanges the two coordinate values:

A'' = (4, 1)

B, because it is the one that is closest together, and it is like a upside down V, unlike Graph A, which is spread out so much.
