Are the directions asking you to solve these ?
Answer:
44
Step-by-step explanation:
5 1/2 / 1/8
turn into improper fraction
11/2 then change to multiplication
11/2*8/1(have to flip)
88/2(multiply across)
simplify=44
P(z < 3)
From the normal distribution table,
P(z < 3) = 0.9987
Answer:
x=4
Step-by-step explanation:
Since both triangles are similar, you can make an equation 12/5x-2 = 16/6x. When you cross multiply you get 72x=80x-32. Then you transfer the 80x and you get -8x = -32. Then you divide by -8 and you get x=4.
Simplify both sides to compare:
6^2 - 2^2 = 36-4 = 32
4(6+2) = 4 x 8 = 32
they are equal to each other.
