Grace is comparing cell phone plans. A prepaid phone plan costs $0.20 per minute and has no monthly fee. A contracted phone plan costs $50 per month and $0.02 per minute. How will the graphs of the monthly costs of the two cell phone plans compare where x represents minutes purchased in a month?
Answer:
The prepaid phone plan will have a steeper line and lower y-intercept.
I hope this is right
Step-by-step explanation:
prepaid phone plan y = .20x
contracted phone plan y = .02x + 50

Isabelle is planning a road trip to her friend's house. She looks at a map that has a scale of 1/2 in. to 25 mi. The road distance between her home town and her friend's town measures 12 in. on the map. If d represents the road distance between the two towns, what is d?
Answer:
600 miles
Step-by-step explanation:
From the question:
1/2 inches = 25 miles
12 inches = x
1/2 × x = 25 × 12
x = (25 × 12) ÷ 1/2
x = 25 × 12 × 2
x = 600 miles
Therefore the road distance between two towns = 600 miles

so the question is 5x - 7 = 28 What does x equal
Answer:
x=7
Step-by-step explanation:
Answer:
7
My Logic:
If you work backwards to simplify the eqation you can get x
take 5x-7=28 and add 7 to both sides. so now the eqaton looks like this: 5x=35. next you divide 5 into both sides and you will get 7!
Hope this helps!

car moves with constant speed. from A to B, car had to arrive on time, but he ride half of the road with 2/3v speed. with what speed car has to ride the rest of the road to go on B location on time?
Answer:
2vStep-by-step explanation:
Let the distance be d and average speed be v.
Half of the distance the speed was 2/3v
Let the speed be xv in the second half of the distance.
Then time is:
d/v = d/2 : (2/3v) + d/2 : (xv)d/v = 3/4(d/v) + (1/2x)(d/v)1 = 3/4 + 1/2x1/2x = 1 - 3/4 1/2x = 1/42x = 4x = 2The rest of the road car has to ride with speed of 2v

Select the correct answer. Which image shows the correct position of on the number line? Which image shows the correct position of -2 1/2 on the number line? A. A B. B C. C D. D
Answer:
Option (A)
Step-by-step explanation:
Option A
Each small segment on the number line measure (0.5) unit.
Red point on the number line is 5 small segment distant from center 0.
So, the position of the point = 0.5 × 5 = 2.5
Since, the point is on the negative side position will be → -2.5
Option B
Position of the point = 0.5 ×3 = 1.5
Option C
Position of the point = 0.5 × 1 = -0.5 (negative sign shows the position of the point on the negative side of the number line)
Option D
Position of the point = 5 × 0.5 = 2.5
Answer the answer is A

According to one source, % of plane crashes are due at least in part to pilot error. Suppose that in a random sample of separate airplane accidents, of them were due at least in part to pilot error. Complete parts (a) and (b) below. a. Test the hypothesis that the proportion of airplane accidents due to pilot error is not . Use a significance level of .
Complete question :
According to one source, 49% of plane crashes are due at least in part to pilot error. Suppose that in a random sample of 100 separate airplane accidents, 61 of them were due to at least in part to pilot error. Complete parts (a) and (b) below. Test the hypothesis that the proportion of airplane accidents due to pilot error is not 0.49. Use a significance level of 0.05.
Determine the null and alternative hypotheses. H0: p Ha: p
Determine the test statistic. Z = (Round to two decimal places as needed.)
Determine the p-value.
Answer:
H0: p = 0.49
Ha: p ≠ 0.49
Zstatistic = 2.45
Pvalue = 0.015
Reject H0, there is sufficient evidence to conclude that population proportion is not 0.49
Step-by-step explanation:
Claim: proportion of airplane accidents due to pilot error is not 0.49
Null and Alternative hypothesis :
H0: p = 0.49
Ha: p ≠ 0.49
Sample size (n) = 100
Number due in part to pilot error = 61
Sample Proportion ph = 61 / 100 = 0.61
Standard Error :
√(p*(1 - p) / n))
√(0.61 * (1 - 0.61) / 100))
√(0. 61 * 0.0039)
= 0.0487749
= 0.049 ( 3 significant figure)
Zstatistic = (ph - p) / SE
Zstatistic = (0.61 - 0.49) / 0.049
Zstatistic = 2.4489795 = 2.45
Using the p value from Z statistic calculator ; α = 0.05, 2 tailed test :
P value = 0.014687 = 0.015
P value < α
0.015 < 0.05
Since the p value is less Than α,
Reject H0, there is sufficient evidence to conclude that population proportion is not 0.49

Which points define the solution set of this linear-quadratic system of equations
Answer:
At point C (-0.5,2)
At point E (1,5)
Step-by-step explanation:
The points that defines the linear quadratic equation system is as follows:
As we can see that the point E and Point C are the solutions set that have an intersections between the parabola i.e. blue and the red line also they are on the both curves at the same time. In addition to this, their coordinates satisfy the both equations in the similar time
Hence, the same is to be considered
Mrs. Rodriquez has 24 students in her class. Ten of the students are boys. Jeff claims that the ratio of boys to girls in this class must be 5:12. What is Jeff’s error and how can he correct it?
Answer:
See Below
Step-by-step explanation:
Total no of students = 24
No of boys = 10
So, no of girls = 24 - 10 = 14
Ratio of boys to girls = 10/14 = 5/7 = 5 : 7
So the ratio of boys to girls should be 5 : 7 and not 5 : 12

Beverly made a root beer float using 1/4 cup of vanilla ice cream for every 3/4 cup of root beer. how much ice cream would Beverly need for one cup of root beer?
Answer:
1/3 cup of ice icream
Step-by-step explanation:
This is a proportions question. Since we know that we need 1/4 cup of ice cream for every 3/4 cup of root beer, we need to find how many cups of ice cream we need for 1 cup of root bear.
We need to find out what times 3/4 makes 1. This can be done with:
(3/4)x = 1
x = 4/3
Now multiply that with 1/4 to get the amount of ice cream.
4/3 times 1/4 = 1/3
