Answer:

x=12

Step-by-step explanation:

Im not sure which measure you're talking about, but I'll show you what I did here:

A triangle = 180 degrees.

4x + 8x + 4x =16x

-8 - 1 - 3 = -12

180 = 16x - 12 -Add 12 to both sides

192 = 16x -divide by 16 to get x by itself

12 = x

Angle A = 88 degrees (8 times 12 then subtract 8)

Angle B = 47 degrees (4 times 12 then subtract 1)

Angle C = 45 degrees (4 times 12 then subtract 3)

What is the Z-score for Paula if she got 1400 on the SAT, the mean was 1100 and the standard deviation was 275? step by step how

Setler [38]

mu = 1100 = population mean

sigma = 275 = population standard deviation

x = 1400 = raw score

z = z score

z = (x-mu)/sigma

z = (1400-1100)/(275)

z = 300/275

z = 1.0909090909091 approximately

z = 1.09

Convention is to round to two decimal places so that you can use a Z table to look up the area under the curve (which helps determine probability).

The positive z score is due to Paula's raw score being above the mean.

r1/r2=4/7 where r1, r2 are radius of a big and small circles respectively

r1/3=4/7

Which inequality is true? Use the number line to help. A number line going from negative 2.5 to positive 2.5 in increments of 0.

alexgriva [62]

Given:

A number line going from negative 2.5 to positive 2.5 in increments of 0.5.

To find:

The inequality which is true.

Solution:

Consider the number line as shown in the below figure.

We know that, on a line as we go to the left direction, the number become smaller and as we go right, the numbers become larger.

From the number line it is clear that -1.5 is on the left side of 0.5. So,

$-1.5$

Hence, option A is incorrect.

-0.5 is on the left side of 0. So,

$-0.5$

Hence, option B is incorrect.

-1.5 is on the left side of -0.5. So,

$-1.5$

Hence, option C is correct.

One half is equal to 0.5.

$\dfrac{1}{2}=0.5$

Hence, option D is incorrect.
