Answer:
its a bunch of numbers thats all i know
Step-by-step explanation:
Four times the difference of a number and seven is at least -52
4(m - 7 ) = - 52 =========> m = -6
Solve:
4(m - 7) = -52
We move all terms to the left:
4(m - 7) - (-52) = 0
We add all the numbers together, and all the variables
4(m - 7) + 52 = 0
We multiply parentheses
4m - 28 + 52 = 0
We add all the numbers together, and all the variables
4m + 24 = 0
We move all terms containing m to the left, all other terms to the right
4m = -24
m = -24 / 4
Answer ==========> m = -6
I hope that helps, and what you are looking for : )
Four times =====> Multiply
Difference ======> Subtract/Take Away
Sum =====> ADD
No she will be short. if you buy 2 dozen witch equals 24 because 12 is one dozen times another is 24. The total will be 13.2 she will not have enough.
Answer:
Step-by-step explanation:
a )
probability of a computer being ancient = .99
probability of a computer being cutting-edge =.01
probability of two selected computer being old
= .99 x .99
= .98 or 98%
b )
probability of 5 selected computers being old
= .99 x .99 x .99 x .99 x .99
= .95 or 95%
c )
probability that at least one of the five selected computers is cutting-edge
= 1 - probability of 5 selected computers being old
= 1 - .95
= .05
