Answer:

x^2 - 2x - 4

Step-by-step explanation:

g(x) - f(x) = (x^2 + 1) - (2x + 5) = x^2 + 1 - 2x -5 = x^2 -2x +(1-5) = x^2 - 2x - 4

aleksklad [387]

Answer:

37

Step-by-step explanation:

Margin of error = critical value × standard error

For 98% confidence, CV = 2.326 (from t table).

Standard error is σ / √n, where σ is the population standard deviation, and n is the sample size.

Plugging in:

5 = 2.326 × 13 / √n

n = 36.6

Rounding up, n = 37.

The table below represents a linear function f(x) and the equation represents a function g(x):
Aneli [31]
Slope of f(x)


Slope of g(x)


PART A)
The slopes of f(x) and g(x) are the same.

PART B)
The equation for line f(x)
y = 4x + b
-1 = 4(0) + b
-1 = b

y = 4x - 1

The function G(x) has a bigger y-intercept. The y-intercept of g(x) is 3, while the y-intercept of f(x) is -1.

Galina-37 [17]

Answer: Ron's z-score is <u>+1.2</u>.

B. 1.2 standard deviation above the mean .

Step-by-step explanation:

Let X deontes the scores of the final exam

Given : Ms. Meyer's statistics class follow a normal distribution with Mean =  82

standard deviation =5.1

Formula : z=\dfrac{X-Mean}{Standard \ deviation}

Ron scored 88 on the final.

So, put x=88

z=\dfrac{88-82}{5.1}=\dfrac{6}{5.1}\approx1.2

Ron's z-score is <u>+1.2</u>.

Also, 88= 86+(1.2 x 5.1) = Mean +1.2 x (standard deviation)

i.e.  This means that Ron's final score is<u> 1.2 standard deviation above the mean </u>.
