Select all the correct answers. The manufacturer of a popular brand of markers is planning to release a new color. To determine which color to add, it mailed out surveys to 5,000 of its customers regarding the general color family they prefer. The returned results are shown in this pie chart. A Pie Chart with four sections representing the color preferences Blues, Greens, Yellows, and Pinks Based on the results, one member of the management team says they should choose the new color from the blue family of colors since a majority of people prefer those colors. Another member doesn’t agree and thinks they should do more research. Which statements would support her request? The difference among the percentages is not statistically significant enough to make the claim of majority. A majority of the management team prefers the yellow family of colors. Not all color families were represented in the survey, which could cause a nonresponse bias. The mail-in survey may have resulted in an undercoverage bias. Since only existing customers were surveyed, the results were not random.

Answer:

x = 20

Step-by-step explanation:

the sum of the interior angles of a triangle is 180°

add expressions for each angle then combine 'like terms':

6x - 5 + 2x - 3 + x + 8 = 180

9x - 8 + 8 = 180

9x = 180

x = 180/9

x = 20

Answer:

y=3x+13

2x=y-9

Step-by-step explanation:

i need to know :(

Answer:

Step-by-step explanation:

Substitute 1 in 2 and solve for x.

2x=y-9

2x=3x+13-9

2x = 3x+4

-x = 4

x = -4

Then use equation 1 to solve for x.

y = 3x+13

y = -12+13

y= 1

The circumference of this circle is equal to 50.24 centimeters.

In Mathematics, a circle can be defined as a closed, two-dimensional curved geometric shape with no edges or corners. Additionally, a circle simply refers to the set of all data points in a plane that are located at a fixed distance (radius) from a fixed point (central axis).

Mathematically, the circumference of a circle can be calculated by using this mathematical expression:

C = 2πr or C = πD

Where:

Based on the image of this circle (See attachment), we can logically deduce that its radius is equal to 8 centimeters.

Substituting the given parameters into the circumference of a circle formula, we have;

Circumference of circle, C = 2 × 3.14 × 8

Circumference of circle, C = 50.24 centimeters.

Answer:

  (b)  y < x-1; y ≤ -2x+2

Step-by-step explanation:

You want to know the inequalities represented on the graph showing a solid line with negative slope and a y-intercept of 2, and a dashed line with positive slope and a y-intercept of -1, where the shading is below both lines.

If the line is included in the solution set (≤ or ≥ is used), the boundary line is graphed as a solid line. If the line is not included in the solution set (< or > is used), the boundary line is graphed as a dashed line.

Here, the line with positive slope is dashed, and the line with negative slope is solid.

  y = x -1 . . . . is a line with positive slope

  y = -2x +2 . . . . a line with negative slope

The shading is below the line for y-values less than those on the line:

  y < x -1 . . . . shading below a dashed line with positive slope

  y ≤ -2x +2 . . . . shading below a solid line with negative slope

These are the inequalities of interest.

Answer:

The area of this trapezoid is equal to 240 [tex]m^{2}[/tex]

Step-by-step explanation:

The area of a trapezoid can be found by using the following formula...

[tex]Area = \frac{(a + b)h}{2}[/tex]   (in this formula a and b are the bases of the trapezoid and h is

                         the height of the trapezoid).

Now we just substitute the values and get...

[tex]Area = \frac{(a + b)h}{2} = \frac{(9 + 15)(20)}{2} = \frac{480}{2} = 240m^{2}[/tex]

Answer:

Step-by-step explanation:

0.25 x 0.044 = 0.011

a. Changing 0.25 to 25 moves the decimal 2 places to the right, and changing 0.044 to 44 moves the decimal 3 places to the right, so once we solve 25 x 44, we have to move the decimal a total of 5 places to the left.

25 x 44 = 1100, then move the decimal 5 places to the left to get 0.01100...but we don't add the zeros at the end.

b. multiplying 1/4 times 0.044 = 0.044/4 = 0.011

Answer:

a)

0.3632 = 36.32% approximate probability that 15 or fewer turn right.

0.369 = 36.9% exact probability that 15 or fewer turn right.

b)

0.4801 = 48.01% approximate probability that at least two-thirds of those in the sample turn.

0.4868 = 48.68% exact probability that at least two-thirds of those in the sample turn.

Step-by-step explanation:

Binomial probability distribution

Probability of exactly x sucesses on n repeated trials, with p probability.

Can be approximated to a normal distribution, using the expected value and the standard deviation.

The expected value of the binomial distribution is:

[tex]E(X) = np[/tex]

The standard deviation of the binomial distribution is:

[tex]\sqrt{V(X)} = \sqrt{np(1-p)}[/tex]

Normal probability distribution

Problems of normally distributed distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

When we are approximating a binomial distribution to a normal one, we have that [tex]\mu = E(X)[/tex], [tex]\sigma = \sqrt{V(X)}[/tex].

Vehicles entering an intersection from the east are equally likely to turn left, turn right, or proceed straight ahead.

This means that [tex]p = \frac{1}{3}[/tex]

50 vehicles

This means that [tex]n = 50[/tex]

Mean and standard deviation:

[tex]\mu = E(X) = np = 50\frac{1}{3} = 16.67[/tex]

[tex]\sigma = \sqrt{V(X)} = \sqrt{np(1-p)} = \sqrt{50\frac{1}{3}\frac{2}{3}} = 3.33[/tex]

a. 15 or fewer turn right.

Using continuity correction, this is [tex]P(X \leq 15 + 0.5) = P(X \leq 15.5)[/tex], which is the pvalue of Z when X = 15.5. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{15.5 - 16.67}{3.33}[/tex]

[tex]Z = -0.35[/tex]

[tex]Z = -0.35[/tex] has a pvalue of 0.3632

0.3632= 36.32% approximate probability that 15 or fewer turn right.

Using a binomial probability calculator, to find the exact probability, we get a 0.369 = 36.9% exact probability that 15 or fewer turn right.

b. at least two-thirds of those in the sample turn.

Turn either left or right, so:

[tex]p = \frac{1}{3} + \frac{1}{3} = \frac{2}{3}[/tex]

The standard deviation remains the same, while the mean will be:

[tex]\mu = E(X) = np = 50\frac{2}{3} = 33.33[/tex]

Two thirds of the sample is 33.33, so at least 34 turning, which, using continuity correction, is [tex]P(X \geq 34 - 0.5) = P(X \geq 33.5)[/tex], which is 1 subtracted by the pvalue of Z when X = 33.5.

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{33.5 - 33.33}{3.33}[/tex]

[tex]Z = 0.05[/tex]

[tex]Z = 0.05[/tex] has a pvalue of 0.5199

1 - 0.5199 = 0.4801

0.4801 = 48.01% approximate probability that at least two-thirds of those in the sample turn.

Using a binomial probability calculator, we find a 0.4868 = 48.68% exact probability that at least two-thirds of those in the sample turn.
