Using the dot plot and statistical concepts, it is found that the correct option is:

  • Their means will be most affected because this value will be an outlier.

<h3>What is a dot plot?</h3>
  • The dot plot shows the <u>number of times each measure appears in the data-set.</u>

In this problem, for both Walter and Janine, the dot plots are cluster between 80 and 90, which means that their grades are in this range.

  • Hence, for both, a grade of 65 would be an outlier, and the measure that is most affected by outliers is the mean.

Hence, the correct option is:

  • Their means will be most affected because this value will be an outlier.

If angle 1 and angle 2 are complementary angles and if the measures of angle 1 is 8 more than the measure of angle 2 determine t
babunello [35]

Answer:

41° and 49°

Step-by-step explanation:

Given:

Angle 1 and angle 2 are complementary angles.

The measures of angle 1 is 8 more than the measure of angle 2.

Question asked:

Determine the measures of angle 1 and 2.

Solution:

Let ∠1 = x

Then ∠2 = x+8   (given)

As we know that sum of complementary angles are 90° and here given that angle 1 and angle 2 are complementary angles which means,

∠1 + ∠2 = 90°

x+x+8=90°

2x +8=90°

Subtracting both sides by 8,

2x=90°-8

2x = 82°

Dividing both sides by 2,

x=41°

∠1 = x=41°

∠2 = x+8

∠2 = 41+8 = 49°

Therefore, the measures of angle 1 and 2 are 41° and 49°

Use Newton's method with initial approximation x1 = −2 to find x2, the second approximation to the root of the equation x3 + x +
nevsk [136]

Answer:

x_2 \approx -1.769

Step-by-step explanation:

Let f(x)=x^3+x+7

So f'(x)=3x^2+1

x_{n+1}=x_n-\frac{f(x_n)}{f'(x_n)}

Let x_1=-2

We are going to find x_2

So we are evaluating -2-\frac{f(-2)}{f'(-2)}

First step find f(-2)

Second step find f'(-2)

Third step plug in those values and apply PEMDAS!

f(-2)=(-2)^3+(-2)+7=-8-2+7=-10+7=-3

f'(-2)=3(-2)^2+1=3(4)+1=12+1=13

So

x_2=-2-\frac{-3}{13} \\\\ x_2=\frac{-26+3}{13} \\\\ x_2=\frac{-23}{13} \\\\ x_2 \approx -1.769

the first Indianapolis 500 auto race took place in 1911. the winning car covered the 500 miles in 6.7 hours. what was the winnin
Vesna [10]

Average speed = (distance covered) / (time to cover the distance)

                         =        (500 miles)      /    (6.7 hours)

                         =            (500 / 6.7)  (mile/hour)

                         =                    74.63 miles per hour.

I imagine there were quite a number of pit stops included in that.

This is faster than I expected when I first read your question.
That's really gettin' with it for cars in 1911 !
