Answer:

Rosalie is correct, a line can have a line of symmetry.

Step-by-step explanation:

If you draw a line, a line of symmetry to that line would be perpendicular to the original line. Because lines are straight, they have an infinite number of lines of symmetry.

A line totally can have a line of symmetry. while it does not have width (therefore cannot put the line of symmetry through its "width"), it does have a length like any other shape. If we take a 4 unit line, we could put the line of symmetry at the 2 unit mark.

A tumor in a rat responds to a new radiation treatment by shrinking 5% with each treatment. How many treatments before the tumor

Nuetrik [128]

A quarter of its original size would be 25% of 100%, right? Therefore, the tumor would have to shrink 75%. If each treatment, the tumor shrinks 5% that would mean it takes 15 treatments to shrink 75 percent.

If this helped, please thank, rate, and give brainliest answer!

Simplify the radical expression.

What is this number in standard form?

Andrej [43]

Answer:

500.61

Step-by-step explanation:

5 multiplied by 100 = 500

1/10 = 0.1, So 6 multiplied by 0.1 = 0.6

1/100 = 0.01, So 1 multiplied by 1 = 0.01

500 + 0.6 + 0.01 = 500.61

A film distribution manager calculates that 4% of the films released are flops. If the manager is correct, what is the probabili

Anit [1.1K]

Answer:

9.34%

Step-by-step explanation:

p = 4%, or 0.04

n = Sample size = 667

u = Expected value = n * p = 667 * 0.04 = 26.68

SD = Standard deviation = $\sqrt{np(1-p)} =\sqrt{667*0.04*(1-0.04)}$ = 5.06

Now, the question is if the manager is correct, what is the probability that the proportion of flops in a sample of 667 released films would be greater than 5%?

This statement implies that the p-vlaue of Z when X = 5% * 667 = 33.35

Since,

Z = (X - u) / SD

We have;

Z = (33.35 - 26.68) / 5.06

Z = 1.32

From the Z-table, the p-value of 1.32 is 0.9066

1 - 0.9066 = 0.0934, or 9.34%

Therefore, the probability that the proportion of flops in a sample of 667 released films would be greater than 5% is 9.34%.
