Answer:
3x - 3 = 20
Step-by-step explanation:
Times is a word that represents multiplication. A number can be represented by x.
3x - 3 = 20
Solving this:
3x - 3 = 20 1. Add 3 on both sides
3x = 23 2. Divide by 3 on both sides
x = 7 2/3
Answer:
Step-by-step explanation:
Midpoint of AC = M(-1, 1.5)
Slope of BM = (1.5 - 3)/(-1 - 5) = ¼
Point-slope equation for line of slope ¼ that passes through B(5,3):
y-3 = ¼(x-5)
3 - 13x - 7x^2 - (5x^2 + 12x - 10)
Distributing the negative over the parentheses chamges the signs:-
= 3 - 13x - 7x^2 - 5x^2 - 12x + 10
adding like terms:-
= -12x^2 - 25x + 13 (answer).
Its B
Sorry this took awhile.
So for Friday, it would be $550
Saturday, $895
Sunday, 1,095
So the total is $2540 if you add the numbers up. Hope this helps!
Answer:
The probability of selecting an odd number given that the chip is black is 0.454.
Step-by-step explanation:
First of all, the value of probability is always less than 1, so the following value of probabilities need to be corrected and are:
Probability of selecting a black chip with an odd number(A)=0.415
Probability of selecting a black chip(B)= 0.915
Probability of A given B is denoted by=P(A | B)
P(A|B) =P(A∩B)/P(B)
P(B)=0.915
P(A∩B)=0.415
P(A|B)=
P(A|B)=0.454
The probability of selecting an odd number given that the chip is black is 0.454.
