1. On which road would there be a larger standard deviation in speed: a backroad or an interstate? Justify your answer

Ashley fills the container with sugar using a bowl. The bowl hold 1/3 cups of sugar. Ashley uses 6 bowls to fill the container.

Degger [83]

Answer:

1 bowl = 1/3 cups

6 bowls = (1/3) * 6

= 2 cups

So, the container hold 2 cups of sugar

The accounting department analyzes the variance of the weekly unit costs reported by two production departments. A sample of 16

dusya [7]

Answer:

$F=\frac{s^2_2}{s^2_1}=\frac{5.5}{2.5}=2.2$

Now we can calculate the p value but first we need to calculate the degrees of freedom for the statistic. For the numerator we have $n_2 -1 =16-1=15$ and for the denominator we have $n_1 -1 =16-1=15$ and the F statistic have 15 degrees of freedom for the numerator and 15 for the denominator. And the P value is given by:

$p_v =2*P(F_{15,15}>2.2)=0.138$

For this case the p value is highert than the significance level so we haev enough evidence to FAIL to reject the null hypothesis and we can conclude that the true deviations are not significantly different

Step-by-step explanation:

Information given

$n_1 = 16$ represent the sampe size 1

$n_2 =16$ represent the sample 2

$s^2_1 = 2.5$ represent the sample deviation for 1

$s^2_2 = 5.5$ represent the sample variance for 2

$\alpha=0.10$ represent the significance level provided

The statistic is given by:

$F=\frac{s^2_2}{s^2_1}$

Hypothesis to test

We want to test if the variations in terms of the variance are equal, so the system of hypothesis are:

H0: $\sigma^2_1 = \sigma^2_2$

H1: $\sigma^2_1 \neq \sigma^2_2$

The statistic is given by:

$F=\frac{s^2_2}{s^2_1}=\frac{5.5}{2.5}=2.2$

Now we can calculate the p value but first we need to calculate the degrees of freedom for the statistic. For the numerator we have $n_2 -1 =16-1=15$ and for the denominator we have $n_1 -1 =16-1=15$ and the F statistic have 15 degrees of freedom for the numerator and 15 for the denominator. And the P value is given by:

$p_v =2*P(F_{15,15}>2.2)=0.138$

For this case the p value is highert than the significance level so we haev enough evidence to FAIL to reject the null hypothesis and we can conclude that the true deviations are not significantly different

ANSWER FOR A BUNCH OF POINTS !!EASY!!

Tasya [4]

The correct option is D for the placement of regular polygon and the rhombus.

<h3>What is defined as the regular polygon?</h3>

A polygon is a two-dimensional enclosed image created by connecting three or more straight lines.
A rhombus is a special parallelogram because it meets the definition of a parallelogram, which is a quadrilateral to two pairs of parallel sides.
A polygon is made up of three parts:

Sides: A side is a line segment that connects two vertices.
Vertices: A vertex is the point where two sides meet.
Interior and exterior angles An interior angle is an angle formed by joining the sides of a polygon within its enclosed surface.

As, all the given figures comes under the regular polygon, all are placed in the left circle.

But the three diagram in white, orange and blue colour are regular polygon along with rhombus.

Thus, all three are placed in the intersection of the both circle of the vein diagram.

Himari is solving the equation 4 ( x - 3 ) = 16. Her first step is 4x - 12 = 16. Which step could be the next step? Select all t

Pani-rosa [81]

Answer:

Her next step would be to add 12 to both sides of the equation

Step-by-step explanation:

Which would make the equation 4x=28

Then you divide both sides by 4 giving you x=7
