Answer:

d. 18 ÷ 3

Step-by-step explanation:

you would want to split the payment evenly.

18 ÷ 3 friends
think, how many times does 3 go into the number 18...
6 times  ⇒ 3 x 6 = 18
now you can split the cost evenly

so your answer would be d. 18 ÷ 3

CORRECT ANSWER GETS A BRAINLIEST

Alex787 [66]

Answer:

B. N(c) = (c-20)/n

Step-by-step explanation:

Given

C(n) = 10n+20

we have to find the inverse of this function

we have to express n in terms of C(n)

C(n) = 10n+20

we have make n independent of n and remove any other term containing on the side of n

subtracting 20 from LHS and RHS

C(n) - 20 = 10n+20 - 20

C(n) - 20 = 10n

dividing LHS and RHS by 10

C(n)/10 - 20/10 = 10n/10

=> n = (C(n) - 20)/10

Now given in problem, N(c) is no of bushels picked

and c is the cost of apple

so in function n = C(n) - 20/10

we replace C(n) with c

and n with N(c)

and then we have

N(c) = (c-20)/n Answer

Find the area of a circle

PtichkaEL [24]

Answer:

28.26 square feet

Step-by-step explanation:

Area of a circle is: $A=\pi r^2$

'r' is the radius.

We are given the diameter of 6ft. Since the diameter is twice the radius, the radius is 3 ft.

6/2 = 3

Using 3.14 for pi:

$A=3.14*3^2\\\rightarrow 3^2=9\\A=3.14*9\\\boxed{A=28.26}$

The area of the circle should be 28.26 square feet.

Suppose that the thickness of one typical page of a book printed by a certain publisher is a random variable with mean 0.1 mm an

marusya05 [52]

Answer:

The probability that the thicknesses at the entire book will be between 49.9 mm and 50.1 mm is 0.97.

Step-by-step explanation:

The complete question is:

Suppose that the thickness of one typical page of a book printed by a certain publisher is a random variable with mean 0.1 mm and a standard deviation of 0.002 mm Anew book will be printed on 500 sheets of this paper. Approximate the probability that the thicknesses at the entire book (excluding the cover pages) will be between 49.9 mm and 50.1 mm. Note: total thickness of the book is the sum of the individual thicknesses of the pages Do not round your numbers until rounding up to two. Round your final answer to the nearest hundredth, or two digits after decimal point.

Solution:

According to the Central Limit Theorem if we have a population with mean μ and standard deviation σ and we take appropriately huge random samples (n ≥ 30) from the population with replacement, then the distribution of the sum of values of X, i.e S, will be approximately normally distributed.

Then, the mean of the distribution of the sum of values of X is given by,

$\mu_{S}=n\mu$

And the standard deviation of the distribution of the sum of values of X is given by,

$\sigma_{S}=\sqrt{n}\sigma$

The information provided is:

$n=500\\\mu=0.1\\\sigma=0.002$

As n = 500 > 30, the central limit theorem can be used to approximate the total thickness of the book.

So, the total thickness of the book (S) will follow N (50, 0.045²).

Compute the probability that the thicknesses at the entire book will be between 49.9 mm and 50.1 mm as follows:

$P(49.9$

$=P(-2.22$

Thus, the probability that the thicknesses at the entire book will be between 49.9 mm and 50.1 mm is 0.97.
