4/21
Step-by-step explanation:
I got the first probability and the second probabilty then multiplied them together.
Answer:
5X + 8Y >= 300; intersection at (-20, 50)
Step-by-step explanation:
let t = work hours
0 < t < 30
X = time lawn mowing
Y = time babysitting.
X + Y < 30
5X + 8Y >= 300
We could solve...
X < 30 - Y
5(30 - Y) + 8Y >=300
150 - 5Y + 8Y >= 300
3Y >=150
Y >=50
then X < -20
intersection at (-20, 50)
Answer:
1: x ^11
2: y ^12
3: x^ 7
Step-by-step explanation:
In 1 we give the sum
In 2 we give the multiple
In 3 we minus
answer:
1/433 (decimal: 0.002309)
step-by-step explanation:
5/2,165
= 1/433
to change 1/433 to decimal we'll divide the numerator by the denominator-
1÷433
=0.00230946882
so we're going to round to the ten-millionths place
5 or more raise the floor, 5 or less let it rest
4>5
so 0.002309
good luck :)
i hope this helps
brainliest would be highly appreciated
have a nice day!
