Find the value of x.

Mathematics
1 answer:
ElenaW [278]3 years ago
7 0

Answer:

x = 3

Step-by-step explanation:

Given 2 intersecting chords, then

The product of the parts of one chord is equal to the product of the parts of the other chord, that is

5x × x = 5 × 9

5x² = 45 ( divide both sides by 5 )

x² = 9 ( take the square root of both sides )

x = \sqrt{9} = 3

Which is perpendicular to the line y=-3x-8y
atroni [7]

Answer:

I believe the answer is y = -7/3x

Step-by-step explanation:

When you rearrange the equation, y = -3x - 8y, you will get -7y = -3x.

We want the equation to be equal to y by itself. So we divide -7 from both sides, giving us the equation y = 3/7x.

The graph that is perpendicular to y = 3/7x is it's reciprocal: y = -7/3x

In Spring 2017, data was collected from a random selection of STA 2023 students. One of the questions asked how many hours they
Arte-miy333 [17]

Answer: 0.22

Step-by-step explanation:

We know that the best point estimate for the difference between two population mean is the difference between their sample means.

Given : For the 39 randomly selected upperclassmen, the sample mean was 0.12 and sample standard deviation was 0.42. For the 35 randomly selected underclassmen, the sample mean was 0.34 and the sample standard deviation was 0.87.

Let A denotes the population of upperclassmen and B denotes the population of underclassmen .

\overline{x}_A=0.12

\overline{x}_B=0.34

Then, the point estimate of the difference in the population mean volunteered between underclassmen and upperclassmen will be :-

\overline{x}_B-\overline{x}_A=0.34-0.12=0.22

Hence, the point estimate of the difference in the population mean volunteered between underclassmen and upperclassmen =0.22
