Let's rewrite the numbers correctly:
 3.2 × 10 ^ 4
 3.6 × 10 ^ 2
 Now let's do the multiplication step by step:
 Step 1:
 The step Kevin made:
 (3.2 * 3.6) * ((10 ^ 4) * (10 ^ 2))
 11.52 * (10 ^ (4 + 2))
 11.52 * 10 ^ 6
 Step 2:
 Rewrite the expression:
 11.52 * 1000000
 Step 3:
 Roll the comma to the right:
 11520000
 Answer:
 the next step that Kevin should apply to his solution is: 
 Step 2:
 Rewrite the expression:
 
11.52 * 1000000
 
Step 3:
 Roll the comma to the right:
 11520000

A recently admitted class of graduate students at a large state university has a mean GRE verbal score of 650 with a standard de
hjlf

Answer:

The answer is below

Step-by-step explanation:

The z score is a score used to determine the number of standard deviations by which the raw score is above or below the mean, it is given by the equation:

z=\frac{x-\mu}{\sigma} \\\\\mu=mean, \sigma=standard\ deviation,x=raw\ score\\\\for\ a\ sample\ n:\\\\z=\frac{x-\mu}{\sigma/\sqrt{n} }

Given that μ = 650, σ = 50. To find the probability that 5 students who have a mean of 490, we use:

z=\frac{x-\mu}{\sigma/\sqrt{n} } =\frac{490-650}{50/\sqrt{5} } =-7.16

From the normal distribution table, P(x < 490) = P(Z < -7.16) = 0.0001 = 0.01%

Since only a small percentage of people score about 490, hence the local newspaper editor should write a scathing editorial about favoritism

Find the value of x?!??????
PilotLPTM [1.2K]

Answer:

x = 31

Step-by-step explanation:

Given:

MN = 20

PQ = x

RS = 42

Required:

Value of x

SOLUTION:

In a trapezoid, the midsegment length equals the sum of both bases divided by 2

This implies that:

PQ = ½(MN + RS)

Plug in the values

x = ½(20 + 42)

x = ½(62)

x = 31
