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

Answers

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

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?​

Answers

Answer:

2v

Step-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 = 2

The rest of the road car has to ride with speed of 2v

Answers

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

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?

Answers

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
