The value of x is 7.....

jenyasd209 [6]3 years ago
4 0

Answer:

7

Step-by-step explanation:

Since both chords are congruent and the distance of the x and 7 are equidistant from the center, then the value of x will also be 7.

Left side chord will have a value of y + 10

The right side chord will have a value of y + 10

Now since the right angles on both sides are equal, then x = 7.

Plz will mark as brainliest ​
Alenkasestr [34]

Answer:

30

Step-by-step explanation:

1/2 x (a+b) x h = area

1/2 x ( 40 + x ) x 50 =  1750

1/2 (40 + x )= 1750/50

20 + 1/2x = 35

1/2 x = 35 - 20

x = 15 x 2

= 30

I hope this is right :)

It appears that people who are mildly obese are less active than leaner people. One study looked at the average number of minute
fredd [130]

Answer:

0.0322; 0.9929

Step-by-step explanation:

Since the data is normally distributed, we use z scores for these probabilities.

The formula for a z score of a sample mean is

z=\frac{\bar{X}-\mu}{\sigma \div \sqrt{n}}

For the sample of mildly obese people, the mean, μ, is 371; the standard deviation, σ, is 65; and the sample size, n, is 6.

Using 420 for X,

z = (420-371)/(65÷√6) = 49/(65÷2.4495) = 49/26.5360 ≈ 1.85

Using a z table, we see that the area under the curve to the left of this is 0.9678.  However, we want the area to the right, so we subtract from 1:

1-0.9678 = 0.0322

For the sample of lean people, the mean, μ, is 528; the standard deviation, σ, is 108; the sample size, n, is 6.

Using 420 for X, we have

z = (420-528)/(108÷√6) = -108/(108÷2.4495) = -108/44.0906 ≈ -2.45

Using a z table, we see that the area under the curve to the left of this is 0.0071.  We want the area under the curve to the right, so we subtract from 1:

1-0.0071 = 0.9929
