Answer:

Step-by-step explanation:

16.) 2/3

You add up the fractions and then reduce.

(5/12 + 3/12 = 8/12 = 2/3)

17.) No because if you add all the fractions together, you only get 7/8. This means the project is not complete yet.

find the circumference and the area of the circle with the radius 9m use the value 3.14 for it do not round your answer be sure

kirill [66]

Explanation:

The circumference and the are of a circle with radius r

are:

$\begin{gathered} A=\pi r^2 \\ C=2\pi r \end{gathered}$

If we use pi = 3.14 and the radius is 9m:

$A=3.14\cdot(9m)^2=3.14\cdot81m^2=254.34m^2$ $C=2\cdot3.14\cdot9m=56.52m$

Answers:

• Area: ,254.34 m²

• Circumference: ,56.52 m

A sensitive measuring device is calibrated so that errors in the measurements it provides are normally distributed with mean 0 a

Artemon [7]

Answer: 0.9660

Step-by-step explanation:

Given: Mean : $\mu =0$

Variance : $\sigma^2=2.00$

⇒ Standard deviation : $\sigma = \sqrt{2}$

The formula to calculate z is given by :-

$z=\dfrac{x-\mu}{\sigma}$

For x= -3

$z=\dfrac{-3-0}{\sqrt{2}}=-2.12132034356\approx-2.12$

The P Value = $P(z$

For x= 3

The P Value = $P(z$

$\text{Now, }P(-3$

Hence, the probability that a given error will be between -3 and 3=0.9660
