Answer:

The answer is \frac{646,449}{68.3} =9,464.85

Step-by-step explanation:

In order to determine the unit rate, we have to know about rates.

In any "rate", the number is representing the fraction of two measures. For example in physics, the velocity is the rate of distance per time, where we divide the distance measure by the time measure.

In this case, we have two measures:

  1. people.
  2. square mile.

So, the rate that relates both measures is:

\frac{people}{square mile} \\\frac{646,449}{68.3}\\ 9,464.85

Finally the unit rate is:

\frac{646,449}{68.3} =9,464.85

The two Marked angles are congruent yes or no will mark brainest​
kompoz [17]

Answer:

true

Step-by-step explanation:

if the vertical lines are not parallel, then the corresponding angles are not congruent.

8x + 2 = 14x - 76

8x - 14x = -76 -2

-6x = -78

x = 13

8(13) + 2 = 14(13) - 76

106 = 106---- equal

the vertical lines is a bit confusing.... they looks like not a parallel lines

Evaluate the following expression:<br> -X- 6x + 10 when x = 5
BigorU [14]

Answer:

-25

Step-by-step explanation:

Evaluate -x - 6 x + 10 where x = 5:

-x - 6 x + 10 = -5 - 6×5 + 10

-6×5 = -30:

-5 + -30 + 10

-5 - 30 + 10 = 10 - (5 + 30):

10 - (5 + 30)

5 + 30 = 35:

10 - 35

10 - 35 = -(35 - 10):

-(35 - 10)

In an all boys school, the heights of the student body are normally distributed with a mean of 70 inches and a standard deviatio
almond37 [142]

Answer:

0.010

Step-by-step explanation:

We solve the above question using z score formula

z = (x-μ)/σ, where

x is the raw score = 63 inches

μ is the population mean = 70 inches

σ is the population standard deviation = 3 inches

For x shorter than 63 inches = x < 63

Z score = x - μ/σ

= 63 - 70/3

= -2.33333

Probability value from Z-Table:

P(x<63) = 0.0098153

Approximately to the nearest thousandth = 0.010

Therefore, the probability that a randomly selected student will be shorter than 63 inches tall, to the nearest thousandth is 0.010.
