Answer:

The answer is 46 units

Step-by-step explanation:

You were correct in multiplying 12 by 4. However, you forgot to notice that the corners of every square were only shaded halfway. All you have to do then is subtract 48 by 2.

What prefix would you use if you wanted an answer that would be equal to 100 times larger than a meter?

just olya [345]

Well, this could be a "hecto" but in practice it's not really used. If you want to use it, you would speak of "hectometers".

if your question would be 1000 times larger, then it would be "kilo" and this one is actually widely used.

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:

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

I need help with this question

Rudiy27

Since the angle is positive, you can find any coterminal angle by applying:

Angle + x = 2π ==> 7π/6 + x = 2π ==> x = 2π - 7π/6

x= 12π/6 -7π/6 = 5π/6

So the angle 5π/6 is the coterminal of 7π/6
