Answer= (7x - 4)(x - 3)
Work=
You’re looking for 2 numbers that add to -4 and multiply to -21.
-7 + 3 = -4
-7 x 3 = -21
So it’s (x - 4)(x - 21)
Divide both by 7, because it is attracted to the x squared.
Remember: if a number is not divisible by 7, the 7 attaches to the x
Answer= (7x - 4)(x - 3)
Answer:
$2.96
Step-by-step explanation:
Here, we want to get the expected value
To get the expected value, we have to multiply each payout by its corresponding probability and add up for all
So what this mean is that the expected value is the summation of the products of each pay out and their probability
We have the expected value calculated as;
0(0.12) + 1(0.2) + 2(0.38) + 5(0.2) + 10(0.1)
= 0 + 0.2 + 0.76 + 1 + 1 = $2.96

Answer:
The radius for A = 1.91
The radius for B = 0.95
Step-by-step explanation:
We are asked to find the circumference
Formula for circumference is
C = 2πr
C - the circumference of a circle
π - pie 22/7
r - radius of a circle
To get r, divide both sides by 2π
C/2π = 2πr/2π
r = C/ 2π
A. 12pie
Circumference = 12
r = 12/ 2 * 22/7
r = 12/ 44/7
r = 12 ➗ 44/7
Hint: changing a division to multiplication, we use the reciprocal of the value
r = 12 * 7/44
r = 84/44
r = 21/11
r = 1.91
B. 6m
Circumference = 6m
r = C/2π
r = 6/ 2 * 22/7
r = 6/ 44/7
r = 6 * 7/44
r = 42/44
r = 0.95
