irina [24]

Answer: Our required probability is 0.99338.

Step-by-step explanation:

Since we have given that

n = 100

p = 0.200

So, $np=100\times 0.2=20>5$

So, we can apply normal approximation.

Mean = 20

Standard deviation = $\sqrt{npq}=\sqrt{100\times 0.2\times 0.8}=\sqrt{16}=4=\sigma$

Since $z=\dfrac{\bar{X}-\mu}{\sigma}$

So, Probability that fewer than 30 but a packet after testing a free sample is given by

$P(X$

Hence, our required probability is 0.99338.

if the smaller of two consecutive intergers is subtracted from two times the larger then the result is 17 . find the intergers

cricket20 [7]

Two consecutive integers (x) and (x+1)
2 (x+1) - (x) = 17
2x + 2 - x = 17
x + 2= 17
x + 2 - 2 = 17 - 2
x=15
and x + 1 = 15 + 1 = 16

15, 16 are your numbers.

Farmer Brown needs to fertilize his hay pasture before spring arrives. He knows that the perimeter of his pasture is 1000 feet a

Pavlova-9 [17]

Answer: 40 bags

Step-by-step explanation:

Given: The dimension of farmers pasture is 1000 feet by 200 feet.

The area of pasture= $1000\ feet\times200\ feet=200,000\ feet^2$

Since, area covered by 1 bag of fertilizer= 5000 square feet

Therefore, the amount of fertilizer required for 1 square feet of area= $\frac{1}{5000}\ of\ bag$

The amount of fertilizer required for 5000 square feet of area= $200,000\times\frac{1}{5000}$

Therefore, the amount of fertilizer required for 5000 square feet of area= 40 bags

If someone puts no job or social services on their rental application and yet they pay rent on time each month … they’re probably doing something illegal.
