Robin randomly selects a number between 1 and 20. What is the probability that the number selected is the square of a natural number?a.1/2
b.-3/20
c.-3/10
d.1/5
e.1/3

Answers

Answer 1
Answer:

Answer: d.(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}}\n\n\Rightarrow\ P=(4)/(20)=(1)/(5)

Hence, The probability that the number selected is the square of a natural number is (1)/(5)

Answer 2
Answer: D is I am pretty sure

The graph shows the functions f(x), p(x), and g(x):Part A: What is the solution to the pair of equations represented by p(x) and f(x)?

Part B: Write any two solutions for f(x).

Part C: What is the solution to the equation p(x) = g(x)? Justify your answer.

Answers

The function f(x) is:

f(x)=x

This is because the line f(x) passes through the points (-1,-1), (0,0), (1,1) etc.

The function p(x) is:

p(x)=mx+C

Whereby (m) is the slope and (C) is a constant.

m=-4/3, as m=tan(ω)=O/A=-4/3 as slope is negative.

Now when y=-3, x=-3.

So:

-3=-4/3 *(-3) +C

-3= 4 + C

C=-7

This means that:

p(x)=-4/3x -7

Now, where p(x)=g(x), x=-6.

p(-6)=-4/3 * (-6) -7

p(-6)=24/3 -7

p(-6)=8-7

p(-6)=1

Therefore:

p(x) and g(x) meet at (-6, 1) and the solution to p(x)=g(x) is x=-6.

D. 6/8

Answers

Answer:

5/12

Step-by-step explanation:

of means multiplication. so multiply 5x2 / 6x2 which is 5/12

Answer:

A. 5/12

Step-by-step explanation:

the "of" in the answer is asking you to multiply.

what you want to do is multiply the numerators and denominators.

5 x 1 = 5

6 x 2= 12

giving you 5/12!
