Which description is true about ​pre-image ABC​ and ​image A′B′C′​ ?
scoray [572]

Answer:

Option (C)

Step-by-step explanation:

From the graph attached,

In ΔABC and ΔA'B'C',

∠A ≅ ∠A'

∠B ≅ ∠B'

Therefore, ΔABC ~ ΔA'B'C'

Corresponding sides of these triangles will be proportional.

\frac{\text{AB}}{\text{A'B'}}=\frac{\text{BC}}{\text{B'C'}}=\frac{\text{AC}}{\text{A'C'}}=\frac{2}{6}

Therefore, ratio of the sides, AC : A'C' = 1 : 3 shows that image triangle A'B'C' is a dilated form of pre-image ABC with a scale factor of 3.

Option (C) will be the correct option.

Kia rides her bicycle at 20 miles per hour. Which equation represents the situation?
sergejj [24]

Answer:

(A)d=20h

Step-by-step explanation:

If Kia rides her bike at 20 miles per hour.

20 miles per hour is referred to as the Kia's Speed.

Now we know that:

$Speed=\frac{Distance \:Travelled}{Time \:taken}

Given:

  • Number of hours traveled=h
  • Distance traveled=d
  • Speed = 20 mph

Substituting these three into the formula above, we have:

20=\dfrac{d}{h}\\

Cross multiply

d=20h

<u>The correct option is A.</u>

A set of quiz scores is shown in the histogram below. The mean of the data set is 20.2, and the (population) standard deviation
Neko [114]

Answer:

13

Step-by-step explanation:

As the mean is 20.2 and the standard deviation is 2.4

The range within the first standard deviation is

(17.8,22.6)

This means that we can safely use the range of (18,22) as we cannot confirm whether the other values fall within the range.

Within this range there are

2+3+4+3+1=13
