Answer: d. \frac{1}{5}

Step-by-step explanation:

The square number between 1 and 20 = 1,4,9,16

The number of squares between 1 and 20 = 4

The total numbers between 1 and 20= 20

The probability that the number selected is the square of a natural number is given by :-

P=\frac{\text{square numbers}}{\text{total numbers}}\\\\\Rightarrow\ P=\frac{4}{20}=\frac{1}{5}

Hence, The probability that the number selected is the square of a natural number is \frac{1}{5}

Which one is the correct answer, thank u
miss Akunina [59]

Answer:

C

Step-by-step explanation:

The rule tells you that (x,y) ->  (x + 1, y - 3), so you take each vertice and add one to the x-values, and subract 3 from the y-values.

(-6, 4) ->  (-6 + 1, 4 - 3)     which simplifies to (-5, 1)

(-3, -2) ->  (-3 + 1, -2 - 3)     which simplifies to (-2, -5)

(2, 1) ->  (2 + 1, 1 - 3)     which simplifies to (3, -2)

Chris Johnson ran the 40- yard dash in 4.24 seconds. What is the rate of speed? Round any answer to the nearest hundredth
sineoko [7]
Distance divided by time is speed. To find the rate of speed, divide 40 yards by 4.24 seconds which is approximately 9.43 yards per second. 9.43 yards per second is the rate of speed.

You want to order carpet for an area in your house. The room measures 12 feet by 10 feet. Remember, Area = Length × Width.
Mashcka [7]

Answer:

403.33

Step-by-step explanation:

The price is in square yd not feet so change ft to yds

3 ft = 1 yd

12 ft = 12/3 = 4 yds

10 ft = 10/3  yds

A = l * w = 4 * 10/3 = 40/3 yd^2 = 13 1/3 yd ^2

Now multiply by the price per yd^2

13 1/3 yd^2 * 30.25 = 403.333333

Rounding to the nearest cent

403.33

A running track in the shape of an oval is shown. The ends of the track form semicircles.
tigry1 [53]

Answer:

Two semi circles would equal one circle.

The perimeter of a circle is PI x diameter.

The diameter of the circle is shown as 56 m

The perimeter of the 2 ends = 56 x 3.14 = 175.84

The length of the inside of the track is given as 130 m, and there are 2 sides so 130 + 130 = 260 m.

Total perimeter = 260 + 175.84 = 435.84 m.
