The answer would be .4% of the 150 would be boys choosing this. Here's my work.
First, I found out what 3/5 of 150 would be (divided by 5, then multiplied by 3)
Then I subtracted that number from 150 and ended up with 60 (since 3/5 of 150 is 90)
And finally, I took 60 and divided that by 150 to get .4% of the 150 students who said their fav flavor of ice cream was chocolate was boys.
Answer: i hope i helped if not im truly sorry
Solving for 9x^2 - 25 = 0
Standard form:
9x2 − 25 = 0
Solutions based on quadratic formula:
x1
= −0 − √ 02 − 4×9×(−25)
2×9
= 0 − 30 × √ 1
18
≈ −1.667
x2
= −0 + √ 02 − 4×9×(−25)
2×9
= 0 + 30 × √ 1
18
≈ 1.667
Extrema:
Min = (0, −25)
Step-by-step explanation: im not dumb and im not smart
Left is plus right is negative -11-(-15)=4 so you know 4 to the left
True. the base of an exponential function must be positive.
