A 78 kg runner exerts a force of 69 N. What is the acceleration of the runner?(use the formula a=F/m)

Answers

Answer 1

Answer:

The answer is 0.88 m/s²

Step-by-step explanation:

To find the acceleration given the mass and force we use the formula

[tex]a = \frac{f}{m} \\ [/tex]

where

a is the acceleration

m is the mass

F is the force

From the question

m = 78 kg

F = 69 N

We have

[tex]a = \frac{69}{78} = \frac{23}{26} \\ = 0.8846153...[/tex]

We have the final answer as

0.88 m/s²

Hope this helps you

Answers

Answer:

Step-by-step explanation:

2x+25=3x-10

3x-2x=25+10

x=35

(3x-10)+(5y)=180

(3(35)-10)+(5y)=180

95+5y=180

5y=180-95

y=85/5

y=17

What number is one tenth of the number 0.9

Answers

Answer:

0.09

Step-by-step explanation:

First off, we can write 0.9 as a fraction. Reading this, we would say "nine tenths"; this means the number in fraction form is 9/10.

The word "of" in mathematics means we multiply. Thus when we take 1/10 "of" 9/10, we multiply the two:

1/10(9/10)

To multiply fractions, multiply the numerators and multiply the denominators:

1/10(9/10) = (1*9)/(10*10) = 9/100

Converting this back to a decimal, we read 9/100 as "nine one-hundredths"; this means decimal form is 0.09.

A $55 pair of shoes was discounted 15 percent, making the sale price $46.75. The discounted price was then discounted again by 10 percent. Explain how you would find the final price of the shoes.

Answers

Answer:

Hi there

Your answer is

$42.08

To find the final price of the shoes, we would use the 15% discounted price, $46.75, as 100% and find 10% discount of that.

46.75 = 100%

/10

4.675 = 10%

Now, subtract 10% from the 15% discounted price

46.75 - 4.675 = 42.075$ Round up

$42.08

Answer:

find the final price by subtracting 10% from the sale price of $46.75 which is $4.68 making the final price $42.07

. A random sample of 100 children with working mothers showed that they were absent from school an average of 6 days per term with a standard deviation of 1.6 days. Provide a 98% confidence interval for the average number of days absent per term for all the children. a. Write down the equation you should use to construct the confidence interval for the average number of days absent per term for all the children. (10 points) b. Determine a 98% confidence interval estimate for the average number of days absent per term for all the children. (10 points)

Answers

Answer:

a) The equation is:

Confidence Interval = Mean ± Z score × Standard deviation/√Number of samples

b) The 98% confidence interval = (5.62784, 6.37216)

Step-by-step explanation:

a. Write down the equation you should use to construct the confidence interval for the average number of days absent per term for all the children. (10 points)

Confidence Interval = Mean ± Z score × Standard deviation/√Number of samples

b. Determine a 98% confidence interval estimate for the average number of days absent per term for all the children. (10 points)

Confidence Interval = Mean ± Z score × Standard deviation/√Number of samples

Mean = 6 days

Standard deviation = 1.6 days

Number of samples = 100

Z score of 98% confidence interval = 2.326

Confidence interval = 6 ± 2.326 × 1.6/√100

= 6 ± 2.326 × 1.6/10

= 6 ± 0.37216

= 6 - 0.37216

= 5.62784

6 + 0.37216

= 6.37216

Therefore, the 98% confidence interval = (5.62784, 6.37216)

The diameter of a circle is multiplied by 10 how does the circumference change?

Answers

Step-by-step explanation:

The circumference of a circle is given by :

C=2πr, r is the radius of the circle

Also, 2r = D, diameter of the circle

⇒ C = πD

If the diameter of a circle is multiplied by 10, it means,

C = π(10)

⇒ C = 10π

Hence, if the diameter of a circle is multiplied by 10, then its circumference becomes 10π.

Emily claims that a tree height of 43 inches is an outlier for the distribution. Based on the 1.5x IQR rule for outliers, is there evidence to support the claim?

Answers

Given:

Emily claims that a tree height of 43 inches is an outlier for the distribution.

To find:

Evidence to support the claim if any.

Solution:

The starting and the end of the box in box plot are first and third quartile respectively.

From the given box plot it is clear that, [tex]Q_1=34[/tex] and [tex]Q_3=38[/tex].

[tex]IQR=Q_3-Q_1[/tex]

[tex]IQR=38-34[/tex]

[tex]IQR=4[/tex]

According to 1.5x IQR rule for outliers, all the data values lies outside the interval [tex][Q_1-1.5\times IQR,Q_3+1.5\times IQR][/tex] are outliers.

Now,

[tex]Q_3+1.5\times IQR=38+1.5(4)[/tex]

[tex]Q_3+1.5\times IQR=38+6[/tex]

[tex]Q_3+1.5\times IQR=44[/tex]

We know that, 43<44.

Since, 43 is not greater than [tex]Q_3+1.5\times IQR[/tex], therefore, 43 is not an outlier and there is no evidence to support the claim.

Therefore, the correct option is D.
