The answer is D :) . just to help you out, here are the rules for clockwise rotation

90* (y,-x)
180* (-x,-y)
270* (-y,x)

for counter clockwise the rules are


90* (-y,x)
180* (-x,-y)
270* (y,-x)

NEED HELP I WILL GIVE THE MOST BRAINLIEST TO THE FIRST ONE THAT ANSWERS
vesna_86 [32]

Answer:

Center: (3, -2)

Radius: 4.

Step-by-step explanation:

The equation of a circle is (x - h)^2 + (y - k)^2 = r^2.

In this case, the equation given is (x - 3)^2 + (y + 2)^2 = 16.

That means that h = 3, and k = -2. In other words, the center of the circle is (3, -2).

The radius will be

\sqrt{16} \\=  \sqrt{4 * 4} \\= \sqrt{4^2}

= 4

Hope this helps!

We wish to give a 90% confidence interval for the mean value of a normally distributed random variable. We obtain a simple rando
coldgirl [10]

Answer: (9.27025,\ 11.12975)

Step-by-step explanation:

Given : Sample size : n= 9

Degree of freedom = df =n-1 =8

Sample mean : \overline{x}=10.2

sample standard deviation : s= 1.5

Significance level ; \alpha= 1-0.90=0.10

Since population standard deviation is not given , so we use t- test.

Using t-distribution table , we have

Critical value = t_{\alpha/2, df}=t_{0.05 , 8}=1.8595

Confidence interval for the population mean :

\overline{x}\pm t_{\alpha/2, df}\dfrac{s}{\sqrt{n}}

90% confidence interval for the mean value will be :

10.2\pm (1.8595)\dfrac{1.5}{\sqrt{9}}

10.2\pm (1.8595)\dfrac{1.5}{3}

10.2\pm (1.8595)(0.5)

10.2\pm (0.92975)

(10.2-0.92975,\ 10.2+0.92975)

(9.27025,\ 11.12975)

Hence, the 90% confidence interval for the mean value= (9.27025,\ 11.12975)
