Answer:

A. 10 weeks

Step-by-step explanation:

Marie's balance is initially $100 less, but she deposits $10 more per week than Oliver does. It will take her 100/10 = 10 weeks to catch up to Oliver's balance.

Oliver and Marie will have the same balance after 10 weeks.

Oliver's balance at that time will be 300 +10×10 = 400.

Marie's balance at that time will be 200 +10×20 = 400. (the same)

Suppose that 3\%3%3, percent of over 200{,}000200,000200, comma, 000 books borrowed from a library in a year are downloaded. The

sleet_krkn [62]

Answer:

The mean of the sampling distribution of the proportion of downloaded books is 0.03 and the standard deviation is 0.0197.

Step-by-step explanation:

Central Limit Theorem

For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean $\mu = p$ and standard deviation $s = \sqrt{\frac{p(1-p)}{n}}$

3% of books borrowed from a library in a year are downloaded.

This means that $p = 0.03$

SRS of 75 books.

This means that $n = 75$

What are the mean and standard deviation of the sampling distribution of the proportion of downloaded books

By the Central Limit Theorem

Mean: $\mu = p = 0.03$

Standard deviation: $s = \sqrt{\frac{p(1-p)}{n}} = \sqrt{\frac{0.03*0.97}{75}} = 0.0197$

The mean of the sampling distribution of the proportion of downloaded books is 0.03 and the standard deviation is 0.0197.

Evaluate each expression

qwelly [4]

Step-by-step explanation:

a = 2
b = 3
c = 5

$\longrightarrow \rm{{\Bigg ( \dfrac{a}{b} \Bigg )}^c} \\ \\ \longrightarrow \rm{{\Bigg ( \dfrac{2}{3} \Bigg )}^5} \\ \\ \qquad \qquad \bigstar \: \boxed{ \bf{ \Bigg ({\frac{x}{y} \Bigg )}^{m} = \frac{ {x}^{m} }{ {y}^{m}} }} \\ \\ \longrightarrow \rm{ \frac{ {(2)}^{5} }{ {(3)}^{5} } } \\ \\ \longrightarrow \bf{ \frac{ 32 }{ 243} }$

Therefore, 32/243 is the answer.

HELP ASAP !!!<br><br> Please explain why

Option 2: whenever it’s < or > it’s a dashed line but when it’s <= or >= it’s a solid line

Option 4: if you’ll insert (0,0) in the equation then you’ll get 0>-2 which is true so (0,0) is a solution. Another way to check is if (0,0) is in the shaded region of the graph

Option 5: in the equation-2 is the y-intercept which proves it intersects at (0,-2) on the y-axis
