I think it is D. Sorry if im wrong

Answer:

The answer is D. Jessica saves twice as much money as Marcus.

Step-by-step explanation:

If you convert 1/4 (Marcus's savings) to a percentage, we get 25%

(multiply 1/4 by 25 to get the fraction 25/100, therefore making it equivalent to 25%)

so now we have Marcus's savings, 25%, and Jessica's savings, 50%.

Marcus obviously did not save more money than Jessica, so we can cross out answer choices A. and C.

Answer choice B. is not correct because 4/5 is equal to 80%, and Jessica did not save 80% as much money as Marcus.

So therefore, the answer is D. we know this because 25 (Marcus's savings) multiplied by 25 is 50, which is Jessica's savings, so this means Jessica saved twice as much money as Marcus.

i know the answer is correct, but sorry if i got anything wrong in my step-by-step explanation. (also ik this is old but i guess this is for people who are doing it now.)

A certain standardized test's math scores have a bell-shaped distribution with a mean of 530 and a standard deviation of 119. Co
kumpel [21]

Answer:

a) 68.2%

b) 31.8%

c) 2.3%

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 530

Standard Deviation, σ = 119

We are given that the distribution of math scores is a bell shaped distribution that is a normal distribution.

Formula:

z_{score} = \displaystyle\frac{x-\mu}{\sigma}

a) P(test scores is between 411 and 649)

P(411 \leq x \leq 649)\\\\= P(\displaystyle\frac{411 - 530}{119} \leq z \leq \displaystyle\frac{649-530}{119})\\\\= P(-1 \leq z \leq 1)\\\\= P(z \leq 1) - P(z < -1)\\= 0.841 - 0.159 = 0.682 = 68.2\%

b) P(scores is less than 411 or greater than 649)

P(x < 411 < x, x > 649)\\=1 = P(411 \leq x \leq 649)\\=1 - 0.682\\=0.318 = 31.8\%

c) P(score greater than 768)

P(x > 768)

P( x > 768) = P( z > \displaystyle\frac{768 - 530}{119}) = P(z > 2)

= 1 - P(z \leq 2)

Calculation the value from standard normal z table, we have,  

P(x > 768) = 1 -0.977 = 0.023 = 2.3\%

Point P is the center of the circle below. What is the exact area
igor_vitrenko [27]

Answer:

Area =192\pi

Step-by-step explanation:

Given

\theta = 120^o

r =24

Required

The area of the shaded sector

This is calculated as:

Area =\frac{\theta}{360} * \pi r^2

This gives

Area =\frac{!20}{360} * \pi *24^2

Area =\frac{1}{3} * \pi *576

Area =\pi *192

Area =192\pi
