Answer:

True.

Step-by-step explanation:

R² is radius to the second power. You were given the diameter, so the radius will be half of that diameter.

3 to the second power, (or 3 x3), is 9.

Step-by-step explanation:

Given data

Diameter =6 yards

Radius R= Diameter/2= 6/2  = 3 yards

R²=3*3=9square yards

Hence R^2 = 9square yards= True

Solve for x. <br> -0.7(0.3x - 0.8) = -4.48
marta [7]
Divide both sides by -0.7 to get rid of that pesky thing in the front
0.3x-0.8=6.4
add 0.8 to both sides
0.3x=7.2
divide both sides by 0.3
x=24

A large cooperation has quality control over its fertilizers. The fertilizes are composed of nitrogen. The fertilizer requires 3
JulsSmile [24]

Answer:

It is impossible that the mean of the sample of 100 fertilizers less than 2 mg.

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 2.5 mg

Standard Deviation, σ = 0.1 mg

We are given that the distribution of percentage of nitrogen score is unknown.

Formula with sampling:

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

P( mean of the sample of 100 fertilizers less than 2 mg)  

P(x < 2)  

P( x < 2) = P( z < \displaystyle\frac{2-2.5}{\frac{0.1}{\sqrt{100}}}) = P(z < -50)  

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

P(x < 2) =0 = 0\%

Thus, it is impossible that the mean of the sample of 100 fertilizers less than 2 mg.
