You need the formula for geometric mean for right triangles as it applies to the altitude. For us, that formula will be $\frac{BD}{AD}=\frac{CD}{BD}$ where BD is your altitude. The formula then, filled in accordingly, would be $\frac{10}{x}=\frac{4x}{10}$ . We cross multiply to get that $4x^2=100$ . Divide both sides by 4 to get $x^2=25$ , so x = 5. Choice C is the one you want.

The area of Jill's soccer net is 3 times larger than area of Peter's soccer net.

<h3> Area of Peter's soccer net</h3>

The area of Peter's soccer net is determined by using area of rectangle as shown below;

A1 = 5.5 ft x 4 ft

A1 = 22 ft²

<h3> Area of Jill's soccer net</h3>

A2 = 5.5 ft x 12 ft

A2 = 66 ft²

<h3>Ratio of the area of their soccer net</h3>

A2/A1 = 66/22

A2/A1 = 3

Thus, the area of Jill's soccer net is 3 times larger than area of Peter's soccer net.

The G.CD of the number is 17 and the L.C.M is 140,If one of the number is 20, Find the other number

Alik [6]

Answer:

HCF Of two nos. is 17

Let another no. be x

we know that HCF ×LCM = Product of two numbers

17×140=20×(x)

20x=2380

x =2380/20

x=119

The other no. is 119

a. #Use shapiro test to test for normality

Yes. The population has a p-value greater than 0.05:

0.05469>0.05

b.From our output, the 98% intervals are:

[8.19016,9.648021]

c. The new interval, [8.19016,9.648021] is wider, but we are more confident that it contains the true mean ( 8.919091)
