Thang decided to borrow $9000 from his local bank to help pay for a car. His loan was for 3 years at a simple interest rate of

Virty [35]

$1620

calculate simple interest ( I) using I = PRT

where P is the amount borrowed, R is rate of interest and T is time in years

note that R = 6% = $\frac{6}{100}$ = 0.06

I = $9000 × 0.06 × 3 = $1620

Ann cleans an apartment in 12 hours and liz cleans an apportment in 18 hours. How long would it take to clean an appartment toge

Tresset [83]

If Ann cleans in 12 hours then she cleans $\frac{1}{12}$ of the apartment per hour. Similarly Liz cleans $\frac{1}{18}$ of the appartment per hour. So together then can clean $\frac{1}{12}+\frac{1}{18}=\frac{5}{36}$ of the apartment for hour. Therefor it will take them $\frac{36}{5}=7.2$ hours to clean.

The general formula $R_{c}=\frac{AB}{A+B}$ can be used as a check if needed.

A marketing consultant observed 40 consecutive shoppers to estimate the average money spent by shoppers in a supermarket store.

KonstantinChe [14]

Answer:

0.998 is the probability that the average money spent by a sample of 40 shoppers is within $10 of the actual population mean.

Step-by-step explanation:

We are given the following information in the question:

Standard Deviation, σ = $21.51

We are given that the distribution of average money spend is a bell shaped distribution that is a normal distribution.

Formula:

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

We have to find:

P( average money spent is within $10 of the actual population mean.)

$= P( z \leq \displaystyle\frac{10\times \sqrt{40}}{21.51}}) = P(z \leq 2.94)$

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

$P(z \leq 2.94) = 0.998$

I WILL MARK AS BRAINLIEST AND AWARD A LOT OF POINTS PLZ HELP!!!!!!!!!!!!Michael, Ronald, Lidia, Alexandra, and Catherine are sha

Marina86 [1]

Answer:

36 fries

Step-by-step explanation:

Michael has a probability of 0.3.

Lidia has a probability of 0.1.

Alexandra has the probability of 0.32.

Catherine has the probability of 0.1.

Let the probability of Ronald be x

Sum of all the probabilities must be 1

So, $0.3+0.1+0.32+0.1+x=1$

$0.82+x=1$

$x=0.18$

So, probability of Ronald is 0.18

We are given that here are 200 fries in the basket.

So, the number of fries that Ronald will eat = $0.18 \times 200 =36$

Hence Ronald will eat 36 fries.
