Answer:
A) 210
Step-by-step explanation:
The percentage of students who have a cell phone plan with company x is student with plan x over total.The total is 130
P(x) = 70/130
The number of students with cell phone company x is found by multiplying the total number of students times the percentage of students with company x
Students with company x = total * P(x)
= 390 * 70/130
= 210
The answer is A.
5(10)+13(14)=232
50 + 182 =232
12(10)+7(14)=218
120 + 98 =218
Answer:
False.
Step-by-step explanation:
A polygon must have straight lines.
Remark
What this is trying to tell you is that you have two factors. Each in turn can be zero, but they cannot be zero at the same time. You will get that kind of question, just not now.
So either - n = 0 or 5n - 4 =0
Solution
- n = 0 Multiply both sides by - 1
(-1)*(-n) = 0*-1
n = 0
5n - 4 = 0 Add 4 to both sides.
5n = 4 Divide by 5
n = 4/5
Comment
B and D are both wrong 4/5 is positive. and those list n as -4/5 which is wrong.
A is wrong because the function will not go to 0 if n = -1
