Answer:

-2.31

Step-by-step explanation:

9/7 multiplied by (-9/5) is -2.31.

You first have to change the denominator into a common factor that each fraction has in common.

Then you just multiply them to get -2.31.

Answer: This question cannot be answered.

Explanation:

If you add three odd numbers, the sum must also be an odd number. To get an even number, you have to add an even number of odd numbers, e.g. 2 or 4. Adding 3 odd numbers to get 30 is therefore not possible. So the question cannot be answered.

Describe the transformation.

Lesechka [4]

Answer:

g(x) = 1/3 (x - 12) .. vertical compression with factor 1/3 from f(x-4)

Step-by-step explanation:

*f(x) = x - 8 ... horizontal translation right 8 units from parent function f(x)=x

f(x-4) = (x-4) - 8 = x - 12 .... horizontal translation right 4 units from f(x)=x-8

g(x) = 1/3 (x - 12) .. vertical compression with factor 1/3 from f(x-4)

Answer:

The 95% confidence interval is $(150\pm 8.8)$ .

Step-by-step explanation:

The information provided is:

$\bar x=150\\\sigma = 20\\n=20$

The critical value for 95% confidence level is:

$z_{\alpha/2}=z_{0.05/2}=z_{0.025}=1.96$

Compute the margin of error as follows:

$MOE=z_{\alpha/2}\cdot\frac{\sigma}{\sqrt{n}}$

$=1.96\times\frac{20}{\sqrt{20}}\\\\=1.96\times 4.47214\\\\=8.7653944\\\\\approx 8.8$

Then the 95% confidence interval is:

$CI=\bar x\pm MOE$

$=150\pm 8.8$

Thus, the 95% confidence interval is $(150\pm 8.8)$ .

Tangent wz and secant WV intersect at point W. Find the length of YV If necessary, round to the hundredths place.

Mila [183]

Answer:

Option B. $YV=5\ units$

Step-by-step explanation:

we know that

The <u>Intersecting Secant-Tangent Theorem,</u> states that If a tangent segment and a secant segment are drawn to a circle from an exterior point, then the square of the measure of the tangent segment is equal to the product of the measures of the secant segment and its external secant segment

In this problem

$WZ^{2}=WV*WY$

substitute and solve for WV

$6^{2}=WV*4$

$WV=36/4=9\ units$

we have that

$WV=WY+YV$

substitute

$9=4+YV$

$YV=9-4=5\ units$
