Farmers often sell fruits and vegetables at farmers’ markets during the summer. Each tomato stand at the Bentonville farmers’ ma
olga nikolaevna [1]

Answer:

the probability that all tomatoes are sold is  0.919 (91.9%)

Step-by-step explanation:

since the random variable X= number of tomatoes that are demanded,  is normally distributed we can make the standard random variable Z such that:

Z=(X-μ)/σ = (83 - 125)/30 = -1.4

where μ= expected value of X= mean of X (since X is normally distributed)  , σ=standard deviation of X

then all tomatoes are sold if the demand surpasses 83 tomatos , therefore

P(X>83) = P(Z>-1.4) = 1- P(Z≤-1.4)

from tables of standard normal distribution →P(Z≤-1.4)=0.081 , therefore

P(X>83) = 1- P(Z≤-1.4)  = 1 - 0.081 = 0.919 (91.9%)

thus the probability that all tomatoes are sold is  0.919 (91.9%)

A b c or d?? Lmk..Brainly
jeyben [28]

Answer:

28.3 (b)

Step-by-step explanation:

To solve circumference, you will need to use the equation C = 2 *pi* r

for this, we will use 3.14 for pi and the radius is 4.5 so this is how we need to solve it

C= 2 pi (4.5)             Solve 2*4.5

C= 9 pi                     Now we input 3.14 for pi and multiply

C= 9(3.14)

C= 28.26                  Now we round to the nearest tenth to get

C=28.3

What is the range of f(x)=e^x?
Tanzania [10]
The range refers to the value of y for which x is define.

So let y=f(x),

y =  {e}^{x}

Try making x the subject to obtain,

x =  ln(y)
x is defined for all real values of y greater than
0.

Hence the correct answer is D.

What is c/22 + 668 = 684 I NEED HELP!!!!!!!!!!!!!!
scoundrel [369]

Answer:

352

Step-by-step explanation:

So first you need to subtract 668 from both sides.

c/22 + 668 = 684

          -668  -668

---------------------------

c/22 = 16

Then multiply both sides by 22.

c/22 * 22 = 16*22

c = 352

Check-

352/22=16

16+668=684
