I believe the answer is B.

Explanation:

The cell phone plan requires 200$ to start. It also requires an additional 50$.
babunello [35]3 years ago
4 0
The answer to this question is B because the initial start up cost is $200, and then there is a $50 per month charge. The x represents the amount of months you would want the phone for. If you only wanted the phone for 1 month, x would be equal to 1. If you wanted the phone for 7 months, x would be equal to 7.

The answer would not be A unless the $50 was the start up cost and the $200 was the monthly cost. This is because it is 50 + 200x which suggests that $200 is the monthly fee and not $50.

The best estimate of the population means is always the sample mean. We have the sample values, using them we can find the sample mean.

The sum of the sampled rates = 248
Sample Size = 10

Mean value of the sample = Sum of Sample Rate/Sample Size

So,

Mean of the sample = 248/10 = 24.8

Therefore, we can say that the best estimate for the population mean is 24.8

Is this equation infinity many solution 5c+9=5c-12
MatroZZZ [7]

Answer:

The answer is no solution.

Step-by-step explanation: First, you would add + 12 to both sides of the equation so that you would have 5c + 21 = 5c. Then, you would subtract 5c from both sides of the equation. This would leave you with 21 = 0. Since this is not true, the equation would have no solution.

Evelyn can run 3 miles in 40 minutes. Which equation can be solved to find m, the number of miles Evelyn can run in 60 minutes?
inna [77]

Answer:

m= 4.5 miles

Step-by-step explanation:

Let the number of miles Evelyn can run be m and can be modeled by the equation below

m= kx

Where x Is the Minutes

When m= 3

x= 40

3= k40

k= 3/40

If x= 60

m=3/40(60)

m = (60*3)/40

m= 180/40

m= 4.5 miles
