Answer:

181.044m²

Step-by-step explanation:

First, work of the surface area of the base (bottom rectangle area)

Formula : base × height

6×2=12m²

Formula : LW+L

For the 8.8 bit i got 83.734 (sorry i can't be asked right now to put down all my working out)

and for the 9 i got 85.31

add them all together we get 181.044

The time that it takes a randomly selected job applicant to perform a certain task has a distribution that can be approximated b

zepelin [54]

Answer:

If the task is performed in less than or equal to 130.8 seconds, then, the individuals qualify for advanced training.

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 150 sec

Standard Deviation, σ = 15 sec

We are given that the distribution of time taken is a bell shaped distribution that is a normal distribution.

Formula:

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

We have to find the value of x such that the probability is 0.10

P(X < x)

$P( X < x) = P( z < \displaystyle\frac{x - 150}{15})=0.10$

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

$\displaystyle\frac{x - 150}{15} = -1.282\\x = 130.8$

Thus, if the task is performed in less than or equal to 130.8 seconds, then, the individuals qualify for advanced training.

Plsss help it’s due today in an hour!!! (test grade)

Answer:

the area is 50.24 $cm^{2}$ .

Step-by-step explanation:

The formula to find area of a circle is A=π $r^{2}$ . A is area, and r is for radius. Since we have the diameter here, we just need to divide by 2 to find the radius. 8÷2=4, so there, the radius is 4. Now we need to square 4, and do 4x4, which equals 16. Now to multiply 16 by π, or 3.14. 16 x 3.14 = 50.24. The final answer is 50.24 $cm^{2}$ . Hope this helped! :]
