Answer:
(5,-15)
Step-by-step explanation:
X to the midpoint, the x coordinate goes up 2 and the y coordinate goes down 10. So from the midpoint to Y, the x coordinate must go up 2 (making it 5) and the y coordinate goes down 10 (making it -15)
Answer:
4s + g = 76.00
4(9)+ g=76.00
36+g=76.00
36-36+g=76-36
g=40 /4
g=10
Step-by-step explanation:
106.00-30=76.00
s= shoes 9.00
g= games
4s + g = 76.00
4(9)+ g=76.00
36+g=76.00
36-36+g=76-36
g=40 /4
g=10
Sum divided by count. Add up all the numbers and divide it by how many numbers it is.
Answer: a) 9.23×10⁻⁶ and b) 0.00144
Step-by-step explanation:
Since we have given that
Number of cards = 52
a) Probability that we draw 3 aces and 2 kings.
As we know that
Number of aces = 4
Number of kings = 4
Number of cards drawn = 5
So, the probability becomes,
(b) a "full house" (3 cards of one kind, 2 cards of another kind)
Since there are 13 sets of each type and we have to select and 2 kinds of it, so, it becomes
So, it becomes,
Hence, a) 9.23×10⁻⁶ and b) 0.00144

Answer: </h3><h3>Fred has <u>20 students</u> and Lee has <u>22 students</u></h3>
=============================================================
Work Shown:
L = number of students in Lee's class
F = number of students in Fred's class
Lee has 1.1 times as many students compared to Fred
This means we have this equation
L = 1.1F
Whatever the value of F is, we multiply that by 1.1 to get the value of L
The two amounts L and F add to 42 total students
L+F = 42
1.1F + F = 42 .... replace L with 1.1F
2.1F = 42
F = 42/(2.1)
F = 20 .... Fred has 20 students
L = 1.1*F
L = 1.1*20
L = 22 .... Lee has 22 students
------------
Check:
L+F = 22+20 = 42
this confirms the answer
