The distribution of SAT scores of all college-bound seniors taking the SAT in 2014 was approximately normal with a mean of 14971
RideAnS [48]

Answer:

P(X<1200) is 0.8212

Step-by-step explanation:

Test statistic (z) = (X - mean)/sd

X is score of a tester = 1200

mean = 1497

sd = 322

z = (1200 - 1497)/322 = -297/322 = -0.92

The cumulative area of the test statistic is the probability that X<1200. The cumulative area is 0.8212.

Therefore, P(X<1200) = 0.8212

Equality Properties

Step-by-step explanation:

<u>Step 1: Define Equation</u>

4x + 9 = 2x + 15

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Subtract 2x on both sides:                    2x + 9 = 15
  2. Subtract 9 on both sides:                      2x = 6
  3. Divide 2 on both sides:                          x = 3

<u>Step 3: Check</u>

<em>Plug in x into the original equation to verify it's a solution.</em>

  1. Substitute in <em>x</em>:                    4(3) + 9 = 2(3) + 15
  2. Multiply:                               12 + 9 = 6 + 15
  3. Add:                                     21 = 21

Here we see that 21 does indeed equal 21.

∴ x = 3 is the solution to the equation.
