Answer:

As this is incomplete, it lacks the value of actual error.

Here, we do not know the actual value. so let's assume it is 1 inch

Relative Error = 6.25 % ≈ 6.3% = D

Step-by-step explanation:

As this is incomplete, it lacks the value of actual error.

We are asked to calculate the relative of the measurement.

Relative error formula = Actual error/Measurement x 100

Here, we do not know the actual value. so let's assume it is 1 inch

Actual value = 1 inch

Measurement = 16 inch

Relative Error = 1/16 x 100

Relative Error = 6.25 % ≈ 6.3% = D

D. 6.3%

Answer:

She will have a loss of $ 120

Step-by-step explanation:

Purchase price of car = $ 3000

20% of 3000 = [tex]\frac{20}{100}*3000[/tex]

                     = 20 * 30

                    = $ 600

Selling price = 3000 + 600 = $ 3600

Reduction price = 20%  of 3600

                          [tex]\frac{20}{100}*3600[/tex]

                       = 20  * 36

                       = $ 720

Current selling price after reduction = 3600 - 720

                                                            = $ 2880

Loss = 3000 - 2880

        = $ 120

Answer:

We fail to reject the null hypothesis, we accept H₀

Step-by-step explanation:

Population proportion        p₀   =  55 %    p₀   =  0,55

Sample  size         n  =  280

Sample mean     p =  51 %            p =  0,51       q = 0,49

n*p   and  n*q   are both bigger than 10 therefore we can approximate the binomial distribution to a normal distribution

Test  Hypothesis

Null Hypothesis                             H₀                   p   =  p₀

Alternative Hypothesis                Hₐ                    p   ≠  p₀

Significance level is  α  = 0,05    but we have a two-tail test then

α/2  =  0,025

z(c)  =  - 1,96

Computing  z(s)

z(s)  =  ( p - p₀ ) / √(p*q)/n

z(s)  =  ( 0,51 - 0,55 ) / √(0,51*0,49)/280

z(s)  =  - 0,04 * 16,73 / 0,5

z(s)  =  -  1,34

Comparing

z(s)   and z(c)

- 1,34    <    - 1,96

| z(s) | < | z(c)|

Then z(s) is in the acceptance region,  we accept H₀

Answer:

11.5

Step-by-step explanation:

Answer:

11.5

Step-by-step explanation:

you have to use this equation to solve it [r = (1/t)(A/P - 1)] and basically just plug the numbers in to get 11.5. (you could also use one of those online calculators)

r = (1/2)((4920/4000) - 1) = 0.115

r = 0.115

Answer:

k = 11

Step-by-step explanation:

Expand brackets

2k - 10 = 12

add 10 on both sides

2k = 22

divide both sides by 2

k = 11

Answer:

Brooks answer is incorrect because he should not shift the brackets to other numbers. First he should distribute number 2 to be multiplied to each number inside the bracket

Answer:

52.6704

Step-by-step explanation:

The lengths of a professor's classes has a continuous uniform distribution between 49.29 min and 55.55 min

Let x = 49.29, y=55.55

Percentile(P) = 54/100 = 0.54

P54 = x+(y-x)p

P54 = 49.29 + (55.55-49.29)*0.54

P54 = 49.29 + 6.26*0.54

P54 = 49.29 + 3.3804

P54 = 52.6704

Answer:

$3.25

Step-by-step explanation:

The grapes costs $2.70 per pound but you're buying 2.5 pounds so take $2.70 x 2.5 = $6.75. Now u just take $10 - $6.75 which equals $3.25 and thats ur answer.

Answer:

You receive 3.25 cash back.

Step-by-step explanation:

2.70 x 2.5 = 6.75

6.75 + ? = 10

A = 3.25

Answer:  The outdoor temperature is 4 degrees below 0 or -4 degrees.

The indoor temperature is 72 degrees above 0 or 72 degrees.

Step-by-step explanation:

We use negative integer to represent loss, below , or withdrawal etc.

On the other hand we use positive integers to show gain , above , deposit etc.

Given statement :   The outdoor temperature is 4 degrees below 0.

So we will represent it by -4 degrees.

The indoor temperature is 72 degrees above 0.

So we will represent it by +72 or 72 degrees.

Answer:

The outdoor temperature is 4 degrees below 0, or

✔ –4

Answer:

Her usual time from home to school is 30 minutes

Step-by-step explanation:

At any point in time;

distance = speed * time

Here, we want to calculate the normal time she spent going from home to school

Let the normal time be x minutes

And the normal speed be t m/min

Today, she increased her speed by 20%

Her speed today will be t + 20/100 * t =

1.2t m/min

Her distance from how to school normally is

xt meters

Now what this means is that, at the increased speed, she was able to get to school 5 minutes earlier

What we are saying is although, she lost 20 minutes initially, she was able to beat down the lateness by 5 minutes

So, the time spent on her increased speed journey is;

(x-5) minutes

At any point in time, the distance will be equal;

Thus, mathematically;

xt = 1.2t(x-5)

xt = 1.2xt - 6t

6t = 1.2xt-xt

6t = 0.2xt

t cancels out

0.2x = 6

x = 6/0.2

x = 30 minutes

Answer:

A. 42.5

Step-by-step explanation:

The triangle shown is an isosceles triangle. An isosceles triangle haas two of its sides and base angles equal. Hence;
