Answer:

number 1 the outliers....................

Answer:  B) The distribution is symmetric

Explanation:

The center of the distribution is the highest point. As you move to the left or right, the heights of each bar steadily decrease. Notice that the right hand side is a mirror copy of the left hand side. This mirroring is exactly what it means to be symmetric. If we had outliers, then we'd have bars that are further away from the main group, but we don't have such a thing happening here.

If the distribution was skewed left, or negatively skewed, then we'd have outliers that are smaller than the main group. On the other hand, if we had a skewed right (positively skewed) distribution, then we'd have outliers larger than the main group. We don't have any of these cases happening, so that's why the data isn't skewed in any way.

An ant weighs 8.8x10 pound and can
carry objects up to 5,000 times greater than
its own body weight.
What is the greatest weight, in pounds, the
ant can carry?
Express your answer in standard form.

Answers

Answer: 880000

Step-by-step explanation: 8.8 x 10^ 5 = 880000

An ant can carry 0.044 pound of weight.

Important information:

Weight of an ant is 8.8x10⁻⁶ poundThey can carry objects up to 5,000 times greater than their own body weight.Standard form:

Weight of an ant in standard form is:

[tex]8.8x10^{-6}=8.8\times \dfrac{1}{1000000}[/tex] pound

[tex]8.8x10^{-6}=0.0000088[/tex] pound

They can carry objects up to 5,000 times greater than their own body weight. So, the possible weight they can carry is:

[tex]0.0000088\times 5000=0.044[/tex]

Therefore, an ant can carry 0.044 pound of weight.

If m1 = 42°, what is m2?

Answers

I’d.k sorry need points

The required measure of angle value of the m2 is 48°.

Given that,
The sum of two angles m1 and m2 is 90, where m1 = 42°,
What is the value of m2 is to be determined.

What is the angle?

The angle can be defined as the one line inclined over another line.

What is simplification?

The process in mathematics to operate and interpret the function to make the function simple or more understandable is called simplifying and the process is called simplification.

m1 + m2 = 90
42 + m2 = 90
m2 = 48°

Thus, the required value of the m2 is 48°.

Suppose a sample of 256 was taken from a population with a standard deviation of 64 centimeters. What is the margin of error for a 68% confidence interval?
A. 6
B. 8
C. 10
D. 4

Answers

The correct margin of error for a 68% confidence interval is option D 4 centimeters.

Let's calculate the margin of error correctly for a 68% confidence interval.

To calculate the margin of error, we need to determine the critical value associated with a 68% confidence interval. For a normal distribution, the critical value is approximately ±1 standard deviation.

Given that the standard deviation is 64 centimeters, the margin of error can be calculated as:

Margin of Error = 1 * (Standard Deviation / √Sample Size)

= 1 * (64 / √256)

= 1 * (64 / 16)

= 1 * 4

= 4

Therefore, the correct margin of error for a 68% confidence interval, based on the given information, is 4 centimeters. The correct answer is option D.

this is solving quadratic functions by square roots

Answers

X1= -9, X2= 5 I hope I helped

Answer:

x = -9 and x = 5

Step-by-step explanation:

[tex] {(x + 2)}^{2} + 1 = 50[/tex]

[tex] = {x}^{2} + 4x + 4 + 1 = 50[/tex]

[tex] = {x}^{2} + 4x + 5 = 50[/tex]

[tex] = {x}^{2} + 4x + 5 - 50 = 0[/tex]

[tex] = {x}^{2} + 9x - 5x - 45 = 0[/tex]

[tex] = x \times (x + 9) - 5(x + 9) = 0[/tex]

[tex] = (x + 9) \times (x - 5) = 0[/tex]

[tex] = x + 9 = 0[/tex]
