What is XY=7a YZ=5a Xz=6a+24 In geometry

Cloud [144]

In light of the fact that point y is the point at which segment xz is divided, the value of the variable an is equal to 4.

<h3>How can I determine what the value of the variable an is?</h3>

Due to the fact that point y divides segment xz into two distinct halves, the following equation may be used to get segment xz's total length:

xz = xy + yz.

The following are the parameters for the test:

xy = 7a. yz = 5a. xz = 6a + 24.

As a result, we need to substitute into the equation and then solve for a.

xz = xy + yz

6a + 24 = 7a + 5a

12a = 6a + 24

6a = 24

a = 24/6

a = 4.

The diameters of bolts produced by a certain machine are normally distributed with a mean of 0.35 inches and a standard deviatio

Fiesta28 [93]

Answer:

15.87%

Step-by-step explanation:

Notice that the mean of 0.35 inches with a standard deviation of 0.01 gives you when you add (to the right of the distribution), exactly 0.36. Since you want to find the probability (or percentage) of the bolts that have diameter LARGER than 0.36 in, that means you want to estimate the area under the Normal distribution curve from 0.36 to the right). See attached image.

We can use the tables of Z distribution for that, or the standard normal tables:

P(x>0.36) = P(z>(0.36-0.35)/0.01) = P(Z>1) = 0.1587 = 15.87%
