It's an acute angle because it's smaller than 90 degrees and isn't a straight line.

Find the -scores that bound the middle 96 of the area under the standard normal curve by using the TI-84 calculator.

Korvikt [17]

Answer:

$\alpha=1-0.96 =0.04$

And $\alpha/2= 0.02$ and if we use the following function on the Ti84 plus we got:

invNorm(0.02,0,1)

invNorm(1-0.02,0,1)

And the values with the middle 96% of the values are:

$z_{\alpha/2}= \pm 2.054$

Step-by-step explanation:

For this case we want to find the limits with the middle 96% of the area below the normal curve, then the significance level would be:

$\alpha=1-0.96 =0.04$

And $\alpha/2= 0.02$ and if we use the following function on the Ti84 plus we got:

invNorm(0.02,0,1)

invNorm(1-0.02,0,1)

And the values with the middle 96% of the values are:

$z_{\alpha/2}= \pm 2.054$

Evaluate the function:<br><br> f(x)=4x−1, find f(9)

Eddi Din [679]

Answer:

f(9) = 35

Step-by-step explanation:

To solve this, you can take 9 and replace both x's with it and then complete the equation;

f(x) = 4x - 1

f(9) = 4(9) - 1

f(9) = 36 - 1

f(9) = 35

Hope this helps!
