he production of pipes has a mean diameter of 3.25 inches and a standard deviation of .15 inches. The shape of the distribution

o-na [289]

Answer:

The probability that a randomly chosen part has diameter of 3.5 inches or more is 0.9525

Step-by-step explanation:

$Mean = \mu = 3.25 inches$

Standard deviation = $\sigma = 0.15 inches$

We are supposed to determine the probability that a randomly chosen part has diameter of 3.5 inches or more

$P(Z \geq 3.5)=1-P(z$

Refer the z table for p value

$P(Z \geq 3.5)=1-0.0475\\P(Z \geq 3.5)=0.9525$

Hence the probability that a randomly chosen part has diameter of 3.5 inches or more is 0.9525

Find A and C,Laws of sines and cosines

stealth61 [152]

Answer:

$AC=15.9976$

Step-by-step explanation:

Law of Sines: $\frac{sin(A)}{a} =\frac{sin(B)}{b} =\frac{sin(C)}{c}$

Step 1: Define

a = 8 ft

A = 30°

b = ?

B = 89°

Step 2: Substitute and Evaluate

$\frac{sin(30)}{8} =\frac{sin(89)}{b}$

$bsin(30)=8sin(89)$

$b=\frac{8sin(89)}{sin(30)}$

$b=16cos(1)$

$b=15.9976$

$AC=15.9976$

Witch set of orderd pairs contains only points that are on the graph of the function y=12-3x

anygoal [31]

You can try then by plotting the points in.
The answer is C

Make sure by plotting in the points, lets take (-5,27)
y = 12 -3(-5)
y = 12 + 15
y = 27
27 = 27
This is correct

Lets try (-1,15)
y = 12 -3(-1)
y = 12 + 3
y = 15
15 = 15
This is correct

Lets try (8,-12)
y = 12 -3(8)
y = 12 - 24
y = -12
-12 = -12
This is correct too.

The correct ordered pairs are C(-5,27),(-1,15),(8,-12)
