Bernice sells 135 seashells by the seashore every day. She sells each sea shell for 3 dollars. For how many days does Bernice ne

slavikrds [6]

Answer:

Bernice would need 6 days assuming that everything remains constant to make $2430.

Step-by-step explanation:

Assuming she sells every single seashell every day.

First, find the total amount she makes per day by multiply the amount she sells them for ($3) with the total amount of sea shells she sells each day ($135):

135 x 3 = $405

Bernice makes $405 each day.

Now, to solve for the amount of days, divide the total amount she wants to make ($2430) with the amount she makes per day ($405):

2430/405 = 6

Bernice would need 6 days assuming that everything remains constant to make $2430.

Consider a set of 7500 scores on a national test whose score is known to be distributed normally with a mean of 510 and a standa

german

$\mathbb P(X>600)=\mathbb P\left(\dfrac{X-510}{85}>\dfrac{600-510}{85}\right)=\mathbb P(Z>1.059)\approx0.145$

So approximately 14.5% of the scores are higher than 600. This means in a sample of 7500, one could expect to see $0.145\times7500\approx10.86$ scores above 600.
