Step-by-step explanation:

Hello!

A pilot study was conducted to test if three food rewards are equally appealing to the participants.

Of 60 participants surveyed:

16 preferred cupcakes (CC)

26 preferred candy bars (CB)

18 preferred dried apricots (DA)

If the three types of food are equally appealing for the participants, you'd expect that their proportions will be equal: P(CC)=P(CB)=P(DA)= 1/3

1.

The objective of this pilot study is to test if the observed frequencies follow a theoretical model/ distribution. To analyze this, you have to apply a Chi Square Goodness to Fit test. [tex]X^2=sum \frac{(O_i-E_i)^2}{E_i} ~~X^2_{k-1}[/tex] Where k= number of categories of the variable.

For this example the statistical hypotheses are:

H₀: P(CC)=P(CB)=P(DA)= 1/3

H₁: At least one of the proportions isn't equal to the others.

2.

To calculate the expected frequencies for each category you have to use the formula: [tex]E_i= n* P_i[/tex] where Pi represents the theoretical proportion for the i category, stated in the null hypothesis.

[tex]E_{CC}= n* P(CC)= 60*1/3= 20[/tex]

[tex]E_{CB}= n*P(CB)= 60*1/3= 20[/tex]

[tex]E_{DA}= n* P(DA)= 60* 1/3= 20[/tex]

3.

The cutoff or critical value indicates the beginning of the rejection region for the hypothesis test. For the Chi-Square tests, the rejection region is always one-tailed to the right, meaning that you'll reject the null hypothesis if the value of the statistic is big. For the goodness to fit test you have k-1 degrees of freedom, so the critical value will be:

Assuming α: 0.05

[tex]X^2_{k-1;1-\alpha /2}= X^2_{2;0.975}= 7.378[/tex]

The rejection region is then X²₂ ≥ 7.378

4.

[tex]X^2_{H_0}= \frac{(O_{CC}-E_{CC})^2}{E_{CC}} + \frac{(O_{CB}-E_{CB})^2}{E_{CB}} + \frac{(O_{DA}-E_{DA})^2}{E_{DA}} = \frac{(16-20)^2}{20} +\frac{(26-20)^2}{20} +\frac{(18-20)^2}{20}= \frac{14}{5}= 2.8[/tex]

4^x can never be 0 or negative, the graph has a horizontal asymptote at y = 0

So the range only includes positive values

We have been given that Sebastian got estimates from 7 companies for his kitchen remodel: $ 27,500 ; $31,000 ; $36,000 ; $92,000; $29,000 ; $30,500 ; $28,500. We are asked to find the best measure of center for the given data.

We can see that our given data set has a large valued data point that is $92,000.

We know that mean is very much affected by large valued outliers. The data point $92,000 will increase the mean. Therefore, mean is not a best measure of center for given data.

We know that median is very less affected by outliers, therefore, median will be best measure of center for the given data.

x < 1 or x > 15

The solution set of the inequalities are,

1) x ∈ [15, ∞)

2) x ∈ (- ∞, 1]

A relation by which we can compare two or more mathematical expression is called an inequality.

Given that;

The inequalities are,

1) 3x + 7 ≤ 4x - 8

2) - 2x + 3 ≥ 1

Now, Simplify the inequality as;

1) 3x + 7 ≤ 4x - 8

⇒ 3x + 7 ≤ 4x - 8

⇒ 7 + 8 ≤ 4x - 3x

⇒ 15 ≤ x

⇒ x ∈ [15, ∞)

2) - 2x + 3 ≥ 1

⇒ - 2x + 3 ≥ 1

⇒ 3 - 1 ≥ 2x

⇒ 2 ≥ 2x

⇒ 1 ≥ x

⇒ x ∈ (- ∞, 1]

Answer:

  2

Step-by-step explanation:

For a quadratic function the average rate of change on an interval is the rate of change at the midpoint of the interval. The rate of change of a function is given by its derivative.

The derivative of f(x) = x^2 is f'(x) = 2x. The midpoint of the interval is (4+(-2))/2 = 1. Then the average rate of change is ...

  f'(1) = 2(1) = 2

The average rate of change of f(x) on [-2, 4] is 2.

__

Alternate solution

The average rate of change is the slope of the line between the end points of the interval:

  m = (y2 -y1)/(x2 -x1)

  m = (f(4) -f(-2))/(4 -(-2)) = (20 -8)/(6) = 2

The average rate of change on [-2, 4] is 2.

Answer:

23x + 18y = 1446

x + y = 72

Step-by-step explanation:

The bakery made $1446 total. We represent this as the cost of each cake ($23) times the number of cakes sold (x) plus the cost of each dozen cupcakes ($18) times the number of cupcakes sold (y).

Thus, 23x +18y = $1446.

The bakery sold 72 items total. We represent this as the number of cakes sold (x) plus the number of each dozen cupcakes sold (y).

Thus, x + y = 72.

Answer:

Moving the decimal 3 places to the right in a decimal number is the same as multiplying the number by 1000.

Answer:

0.004

Step-by-step explanation:

Since 4/10 is 0.4 and 4/100 is 0.04, 4/1000 must be 0.004

Answer:

0.004

Step-by-step explanation:

[tex]\frac{4}{1000}[/tex] is basically [tex]4 \cdot 10^{-4[/tex] (if you've learned scientific notation), so all you have to do is move the decimal to the left four times. That gives us

[tex]4.0\\0.4\\0.04\\\boxed{0.004}[/tex]

More depth:

[tex]10^{-4[/tex] also equals 0.001, so [tex]4 \cdot 0.001 = \boxed{0.004.}[/tex]

  A. Side lengths of 4 units and 2 units and a nonincluded angle of 30°

Step-by-step explanation:

Both triangles have sides marked 2 units and 4 units, but the angle is not between them. The angle is opposite the short side in one triangle (which will be a right triangle), and opposite the long side in the other triangle (which will be an obtuse triangle). The sides and angles of the two triangles will not have the same measures, and neither will have an angle of 100°.

Answer:

No. of Small Beverage = x = 10

No. of Large Beverage = y = 12

Step-by-step explanation:

Analyzing the given situation, we can form two algebraic equations.

Since, she has 100 lemons and 4 lemons are required for small beverage, while 5 lemons are required for large beverage. So, we can form the equation:

4x + 5y = 100   --------- eqn (1)

where,

x = No. of small beverages sold

y = No. of large beverages sold

Similarly, she has 180 table spoons of sugar and 6 table spoons are required for small beverage, while 10 table spoons are required for large beverage. So, we can form the equation:

6x + 10y = 180   -------- eqn (2)

From eqn (1):

x = (100 - 5y)/4   ------- eqn (3)

Substituting this value of x in eqn (2)

(6)(100 - 5y)/4 + 10y = 180

10 y - 7.5 y= 180 - 150

2.5 y = 30

y = 30/2.5

y = 12

Using this value of y in eqn (3)

x = [100 - (5)(12)]/4

x = 10

Therefore, in order to maximize the earnings the kid should sell following number of each beverage:

No. of Small Beverage = x = 10

No. of Large Beverage = y = 12

Answer:

The new volume would be 14,850cm³.

Step-by-step explanation:

The volume of a rectangular prism is:

[tex]V = l*w*h[/tex]

In which l is the length, w is the width and h is the height.

Dimensions tripled.

So [tex]l = 3l, w = 3w, h = 3h[/tex]

The modified volume will be:

[tex]V_{m} = 3l*3w*3h = 27*l*w*h = 27V[/tex]

Volume of 550 cm³ before the dimensions are tripled.

This means that [tex]V = 550[/tex]

New volume:

[tex]V_{m} = 27*550 = 14850[/tex]

The new volume would be 14,850cm³.

Answer:

the answer is (40,96)

Step-by-step explanation:

Point P on the directed line segment from K to J has x and y coordinates that are three-fifths of the length of the line segment from K to J

(85, 105).

The coordinates point to any point can be found by using the following formula.

X = [m/(m + n)](x₂ - x₁) + x₁

Y =  [m/(m + n)](y₂ - y₁) + y₁

Given, On a coordinate plane, a line is drawn from point K to point J. Point K is at (160, 120) and point J is at (negative 40, 80).

The x- and y- coordinates of point P on the directed line segment from K to J such that P is Three-fifths the length of the line segment from K to J is;

X = [m/(m + n)](x₂ - x₁) + x₁

X = [3/(3 + 5)](- 40 - 160) + 160.

X = - 75 + 160.

X = 85.

Y =  [m/(m + n)](y₂ - y₁) + y₁

Y =  [3/(3 + 5)](80 - 120) + 120.

Y = - 15 + 120.

Y = 105

As a result, point P's x and y coordinates are such that P is three-fifths the length of the directed line segment from K to J (85, 105).
