Answer:

D. Testing the null hypothesis that the mean difference equals 0 is not equivalent to determining whether the confidence interval includes 0

Step-by-step explanation:

Dependent samples are samples that are related to one another.

In a hypothesis test, the hypothesis test and the confidence interval are equivalent in the sense that they result in the same conclusion.

However, in an hypothesis test , we fail to reject the null hypothesis if the rejection region is greater than the t-test statistics. It is therefore crucial to understand that if the true mean is zero. the confidence interval level for the mean of differences within the lower limit and the upper limits must contain zero , which implies the mean difference and the confidence interval  are equivalent.

Gene is playing a game with a bag of marbles. 3 of the marbles are blue, 4 are green, and 7 are yellow. See below for awarded prizes. $2 green $0.5 yellow $4 blue What is the expected cost (or payout for Gene's game?

Answers

Answer:

$23.5

Step-by-step explanation:

Gene is playing a game with a bag of marbles. If 3 of the marbles are blue, 4 are green, and 7 are yellow and awarded prices for the marbles are $2 green $0.5 yellow $4 blue, the expected payout for Gens game is expressed as shown;

If a blue marble costs $4, 3 blue marbles will cost 3*$4 = $12

If a green marble costs $2, 4 green marbles will cost 4*$2 = $8.0

If a yellow marble costs $0.5, 7 yellow marbles will cost 7*$0.5 = $3.5

Total payout for Gene's game will be the equivalent to $12+ $8 + $3.5 = $23.5.

Hence Gene expected cost will be $21.5

What is the solution to the system of linear equations? Write you answer as a coordinate. 2x − y = 4 5x + 2y = 10 Show All Work !!

Answers

Answer:

(2, 0)

Step-by-step explanation:

2x - y = 4

5x + 2y = 10

Solve by elimination by multiplying the top equation by 2, so the y values will cancel out (-2y + 2y = 0)

4x - 2y = 8

5x + 2y = 10

Add them together and solve for x:

9x = 18

x = 2

Plug in 2 as x in one of the equations to find y:

2x - y = 4

2(2) - y = 4

4 - y = 4

-y = 0

y = 0

Answer:

135 units²

Step-by-step explanation:

The area (A) of a parallelogram is calculated as

A = bh ( b is the base and h the perpendicular height )

To calculate h use Pythagoras' identity on the right triangle on the left

h² + 8² = 17²

h² + 64 = 289 ( subtract 64 from both sides )

h² = 225 ( take the square root of both sides )

Answers

Answer:

6 children

Step-by-step explanation:

Given

[tex]1\ Pencil = \$0.59[/tex]

[tex]1\ Notebook = \$1.09[/tex]

Required

Determine the number of students that can get pencils and notes worth $15

First, we need to calculate the amount that can be allotted to a child

[tex]1\ child= 1\ Notebook + 2\ Pencils[/tex]

[tex]1\ child= 1 * \$1.09 + 2 * \$0.59[/tex]

[tex]1\ child= \$1.09 + \$1.18[/tex]

[tex]1\ child= \$2.27[/tex]

From the given parameters, we have that

[tex]n\ children= \$15[/tex]

Where n is the number of child

Represent both as ratios;

[tex]1 : 2.27 = n : 15[/tex]

Convert to division

[tex]\frac{1}{2.27} = \frac{n}{15}[/tex]

Multiply both sides by 15

[tex]15 * \frac{1}{2.27} = \frac{n}{15} * 15[/tex]

[tex]\frac{15}{2.27} = n[/tex]

[tex]6.608 = n[/tex]

[tex]n = 6.608[/tex]

Because "a child" is discrete, we have to round down the above figure to

[tex]n = 6[/tex]

Hence, the maximum number of children that can be provided with supplies worth $15 is 6

The correlation between two variables on a graph gives the relationship between those variables. Depending on the nature of these variables plotted on the graphs, the correlation is named.

What is meant by correlation?In a scatterplot, the data points of an individual with two distinct variables are related. This relationship is called 'correlation'. The relationship between any two variables plotted on any graph is named to be a correlation.

Depending on the type of relation between the variables, the correlation is categorized into three major types. They are

i) Positively correlation

ii) Negative correlation

iii) No correlation

What is meant by positively correlated?The variables plotted on a graph are said to be positively correlated, if both the variables increase with respect to each other.E.g.: In a graph, if the values of y increase as the value of x increases, then they are said to be positively correlated.

What is meant by negatively correlated?The variables plotted on a graph are said to be negatively correlated, if one of the variables increases, the other variable get decreases.E.g.: In a graph if the values of y decrease as the value of x increases, then they are said to be negatively correlated.

What is meant by no correlation?The data points for the two variables are plotted randomly on the graph. If there is no relation between any two points of those two variables, then such a relation is said to be 'no correlation'.E.g.: In a graph, if the values of x and y are randomly located, then there is no correlation between them.

Mr Hamar had rupees 4,400 hie purchase 6 kg of rice at Rupess 75 for KG ,2 packets of oil at rupees 125 per packet and he gave rupees 3,300 to his wife if he divided the remaining Sum between his son and daughter equally find the share of each of them​

Answers

Step-by-step explanation:

Total rupees= 4400

Price of 6kg rice = 75 x 6 = 450

Price of 2 packets oil = 125 x 2 = 250

Amount given to wife = 3300

Total = 450 + 250 + 3300 = 4000

Remaining amount = 4400 - 4000 = 400

Share of son and daughter = 400 ÷ 2 = 200

So his son and daughter both get 200

A box contains 20 equal-sized balls, numbered 1 to 20. Two balls are drawn at random simultaneously. What is the probability that the numbers on the two balls will differ by more than 2

Answers

Answer:

P = 0,7947       or    79,47%

Step-by-step explanation:

We have 20 balls, the total possible outcomes drawn two balls simultaneously is:

C =  m! /n! *( m - n )!

C = 20!/2! *( 20 - 2)!

C= 20*19*18!/ 2* 18!

C  =  20*19/2

C = 190

Now the number of successful outcomes x ( those where balls differ by more than 2 is)

x = total numbers of outcomes  -  20  ( outcomes differing in 1 ) - 19 (outcomes differing in 2 )

x =  190 - 39

x = 151

Then the probability  of drawing tw balls with numbers differing n mr than two is

P = successful outcomes / total outcomes

P = 151/190

P = 0,7947       or    79,47%

You weigh six packages and find the weights to be 28, 22, 52, 25, 49, and 46 ounces. If you include a package that weighs 142 ounces, which will increase more, the median or the mean?

Original Median (28+46)/2 = 37

Original Mean (222/6) = 37

New Median (46)

New Mean (52)

Mean increases the most.

The mean will increase more.

We have weights of six packages  28, 22, 52, 25, 49, and 46.

We have to find if we include a package that weighs 142 ounces, which will increase more, the median or the mean.

What is the formula to find the Median of a set of odd number of elements (say N) ?

If a set consist of odd number of elements, then the median of that set of numbers is the is the element at the position [tex]\frac{(N+1) }{2}[/tex].

If we don't include the package of 142 ounce, then -

Mean = [tex]\frac{28 + 22 + 52 + 25 + 49 + 46}{6} = 37[/tex]

Median = [tex]\frac{52 + 25}{2} = 38.5[/tex]

After including the package of 142 ounce,

Mean = [tex]\frac{28 + 22 + 52 + 25 + 49 + 46+142}{6} = 52\\[/tex]

Median = Element at [tex]\frac{(N+1) }{2}[/tex] position = 25

Machine A and Machine B are each used to make 660 widgets. It takes Machine A x hours longer to produce 660 widgets than Machine B. Machine B produces y % more widgets per hour than Machine A. How long does it take Machine A to make 660 widgets?

Answers

Answer:

A. x + 100x/y

Step-by-step explanation:

Machine A= x hours longer to produce 660 widget than machine B

Machine B produces y% more widget per hour than machine A

let

b = Number of hours it takes Machine B to make 660 widgets.

Time taken for Machine A to make the 660 widgets = x + b.

Rate of Machine B = 660/b

Rate of Machine A = 660 / (x + b).

Machine B produces y% more widgets per hour than Machine A:

660 / (x + b)(1 + y/100) = 660/b

1 / (x + b)(1 + y/100) = 1 / b

Multiply both sides by (x+b)

1 + y/100 = (x + b)/b

1 + y/100 = x/b + 1

Subtract 1 from both sides

y/100 = x/b

Take the inverse of both sides

100/y = b/x

Make b the subject

100x/y = b

b=100x/y

The time taken for Machine A to make the 660 widgets is x + b = x + 100x/y.

Answer is A. x + 100x/y

For the given graph, a. describe the end behavior,
b. determine whether it represents an odd-degree or even-degree polynomial function, and
c. state the number of real zeros.

Answers

Answer:

See below.

Step-by-step explanation:

A)

The end behavior is basically how the function behaves as it approaches negative or positive infinity.

As the function approaches negative infinity, we can see that the graph is going up. In other words:

[tex]f(x)\rightarrow\infty\text{ as }x\rightarrow-\infty[/tex]

As the function approaches positive infinity, we can see that the graph is going down. In other words:

[tex]f(x)\rightarrow-\infty\text{ as }x\rightarrow\infty[/tex]

B)

In even-degree polynomials, both ends of the graph will be going the same way. In this graph, the two ends are going opposite ways so this is an odd-degree function.

C)

The number of real zeros is simply the amount of times the graph crosses the x-axis. In the graph, the function does this three times. Thus, the number of real zeros is 3.
