Answer 2

Answer:

c=19

Step-by-step explanation:

110-91=19

129-110=19

148-129=19

4x19 = 76 (91-76=15)

76+15 =91

5x19= 95 ( 110-95=15)

95+15= 110

6x19 = 114 (129-114 =15)

114+15=129

7x19=133 ( 148-133 =15)

133+15 = 148

There's sufficient evidence to reject the null hypothesis between the treatment group and placebo group.

How to illustrate the hypothesis?

From the complete information, the value of the test statistic is -1.76 and the p-value is 0.085.

In this case, there's sufficient evidence to reject the null hypothesis. Therefore, there's evidence to warrant the rejection of the claim that the two samples are from population with same mean.

present
n = 200
x= 31
(Round to two decimal places as needed.)
Z=

Answers

Answer:

The z-test statistic for a hypothesis test in which the null hypothesis states that the population proportion, p, equals 0.14 if the following sample information is present (n = 200; x = 31) is z = .6114.

Step-by-step explanation:

The z-test statistic formula is:

[tex]\displaystyle z=\frac{\hat{p}-p}{\sqrt{\frac{p(1-p)}{n} } }[/tex]

We are given x = 31 and n = 200, so we can solve for [tex]\hat{p}[/tex] : 31/200 = .155.

The population proportion, [tex]p=.14[/tex], is given in the problem.

We can substitute the known values into the z test statistic formula:

[tex]\displaystyle z = \frac{.155-.14}{\sqrt{\frac{.14(.86)}{200} } }[/tex][tex]\displaystyle z=\frac{.015}{\sqrt {.000602}}[/tex][tex]z=.6114[/tex]

The z-test statistic for this problem is z = .6114.

A recipe called for using 5 1/8 cups of flour before baking and another 8 7/9 cups after baking. What is the total amount of flour needed in the recipe?

Answers

Answer: 13 [tex]\frac{65}{72}[/tex]

Step-by-step explanation:

This question is asking us to find the total flour used, so we will add the two amounts together.

5 1/8 + 8 7/9

5 + 8 = 13

1/8 + 7/9 = 9/72 + 56/72 = 65/72

13 + 65/72 = 13 [tex]\frac{65}{72}[/tex]

The recipe calls for 13 [tex]\frac{65}{72}[/tex] cups of flour.

charlie stands at point A while holding the control line attached to a model airplane. the plane travels 120 feet counterclockwise from point b to point c about how long is the control line

Answers

The counterclockwise direction of the airplane implies that it moves in the opposite direction

The control line could be 60 feet long

How to determine the length of the control line?

The question is incomplete, as the figure that represents the control line and other parameters are not given.

However, a possible solution is as follows.

From the question, we understand that the airplane travels 120 feet counterclockwise.

The counterclockwise direction could represent that points B and C are on either sides of point A, such that:

AB = AC = 0.5* BC

So, we have

AB = 0.5* 120

AB = 60 feet

Hence, the control line could be 60 feet long

The vertex of the function is (-4, -6), the axis of symmetry is x= -4 and the y-intercept is (0, 10).

What is the function?

Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.

The given function is y=x²+8x+10.

Rewrite in vertex form and use this form to find the vertex (h, k).

(-4, -6)

The axis of symmetry is x= -4

To find the x-intercept, substitute in 0 for y and solve for x. To find the y-intercept, substitute in 0 for x and solve for y.

x-intercept(s): (-4+√6, 0), (-4-√6, 0)

y-intercept(s): (0, 10)

Therefore, the y-intercept is (0, 10).

Which statement is true about every exterior angle of any quadrilateral inscribed in a circle?

The measure of an exterior angle is equal to the measure of the nonadjacent interior angle.

The measure of an exterior angle is equal to the measure of an adjacent interior angle.

The measure of an exterior angle is equal to the average of the measures of the two adjacent interior angles.

The measure of an exterior angle is equal to the difference of the measures of the two adjacent interior angles.

Answers

Answer:

Step-by-step explanation:

In an inscribed quadrilateral, opposite angles are supplementary.

An exterior angle of a quadrilateral is supplementary to the adjacent interior angle.

Since the exterior angle is supplementary to both the adjacent interior angle and to the opposite interior angle, the exterior angle and the opposite interior angle are congruent.

Determining which numbers are less than 5:

A number less than 5

⇒ x < 5

When all the numbers in the spinner are substituted in the inequality, we can see that only three numbers are less than 5.

⇒ 2, 3, and 4

Reviewing the formula to calculate probability:

[tex]\dfrac{\text{Total numbers less than 5}}{\text{Total numbers in the spinner}} = \text{Probabilty of getting less than 5}[/tex]

Substituting the values in the formula:

[tex]\dfrac{\text{Total numbers less than 5}}{\text{Total numbers in the spinner}} = \text{Probabilty of getting less than 5}[/tex]

[tex]\bullet \ \text{Total numbers less than five: 3}[/tex]

[tex]\bullet\ \text{Total numbers in the spinner} = 4[/tex]

[tex]\implies \boxed{\dfrac{3}{\text{4}} = \text{Probabilty of getting less than 5}}[/tex]

ft²
Right pentagonal prism. The height of the prism is 8 ft. The base has two pairs of parallel sides. The sides are consecutively labeled 5 ft, 3 ft, 5 ft, 2 ft, and 7 ft. The parallel sides are those labeled 3 ft and 7 ft, and 5 ft and 2 ft.

Answers

The amount of material needed for the containers is its surface area

The amount of material needed for the 8 containers using the assumed parameters is 3080 square feet

How to determine the amount of material?

The question is incomplete, as the figure of the right pentagonal prism is not given.

So, I will provide a general explanation.

The surface area (SA) of a right pentagonal prism is:

SA = 5b(a + h)

Where:

b represents the base lengtha represents the apothemh represents the height

From the question, we have the height of the prism to be 8 ft.

Assume that:

a = 3 ft and b = 7 ft

The equation becomes

SA = 5 * 7 * (3 + 8)

Evaluate the product

SA = 385

The amount of material needed for the 8 containers would be:

Amount = 8 * 385 square feet

Amount = 3080 square feet

Hence, the amount of material needed for the 8 containers using the assumed parameters is 3080 square feet
