Check the picture below.

well, g(x) + 1 is simply a vertical shift upwards of 1 unit, if the vertex before that had a y-coordinate of 4, then later on became 4+1 or 5, so the new vertex is simply (3 , 5).

Suppose that at a state college, a random sample of 41 students is drawn, and each of the 41 students in the sample is asked to

ra1l [238]

Answer:

The confidence interval for 90% confidence would be narrower than the 95% confidence

Step-by-step explanation:

From the question we are told that

The sample size is n = 41

For a 95% confidence the level of significance is $\alpha = [100 - 95]\% = 0.05$ and

the critical value of $\frac{\alpha }{2}$ is $Z_{\frac{\alpha }{2} } =Z_{\frac{0.05 }{2} }= 1.96$

For a 90% confidence the level of significance is $\alpha = [100 - 90]\% = 0.10$ and

the critical value of $\frac{\alpha }{2}$ is $Z_{\frac{\alpha }{2} } =Z_{\frac{0.10 }{2} }= 1.645$

So we see with decreasing confidence level the critical value decrease

Now the margin of error is mathematically represented as

$E = Z_{\frac{\alpha }{2} } * \frac{s}{\sqrt{n} }$

given that other values are constant and only $Z_{\frac{\alpha }{2} }$ is varying we have that

$E\ \ \alpha \ \ Z_{\frac{\alpha }{2} }$

Hence for reducing confidence level the margin of error will be reducing

The confidence interval is mathematically represented as

$\= x - E < \mu < \= x + E$

Now looking at the above formula and information that we have deduced so far we can infer that as the confidence level reduces , the critical value reduces, the margin of error reduces and the confidence interval becomes narrower

What is the solution to the equation t-15=76

geniusboy [140]

Answer:

T = 91

Step-by-step explanation:

Simplifying

T + -15 = 76

Reorder the terms:

-15 + T = 76

Solving

-15 + T = 76

Solving for variable 'T'.

Move all terms containing T to the left, all other terms to the right.

Add '15' to each side of the equation.

-15 + 15 + T = 76 + 15

Combine like terms: -15 + 15 = 0

0 + T = 76 + 15

T = 76 + 15

Combine like terms: 76 + 15 = 91

T = 91

Simplifying

T = 91

If a translation maps point (3, 2) to (5,3); or T:(3, 2) - (5,3), indicate the image for (2,4)

Zinaida [17]

Answer:

Step-by-step explanation:

Note that for (3, 2) → (5, 3)

The x- coordinate of the image is 2 more (+ 2) than the original and the y- coordinate of the image is 1 more (+ 1) than the original, that is

(x, y ) → (x + 2, y + 1 ) ← rule to obtain image, hence

(2, 4 ) → (2 + 2, 4 + 1 ) → (4, 5 ) → A
