Answer:

The price of each game is $44.99, so P = 44.99

Equation:  2p + 194.99 = 284.97

Step-by-step explanation:

284.97 - 194.99 = 89.98

89.98 divided by 2 = 44.99

Step-by-step explanation:

Answer:

When simplified, the square root of 23 is a non-terminating and non-repeating decimal. This, and the fact that it can't be written as a fraction is why it is an irrational number.

I would say September 10 just because it takes 27 days, 7 hours, and 43 minutes for our Moon to complete one full orbit around Earth.

Step-by-step explanation:

Step-by-step explanation:

a

the study is experimental as we do not just observe students performance. 2 techniques were also randomly assigned. there is control over teaching techniques and performance is also observed.

b.

these are the 3 factors: high school, instructions type, scores.

high school has 2 levels. level 1, is 3 high school. level 2: each high school has 4 sections and these 4 have 24 students.

instructions type: 1 level divided into standard and computer based.

scores: 0 ( no level)

c.

high school has between subject combination since there are 3 schools and 4 sections.

instructions type has between too. since there are two different types.

we have 24 students in each section which are within subjects.

d.

score on test is dependent variable

e.

student is basic experimental unit.

[tex]\tt Step-by-step~explanation:[/tex]

In order to solve for both x and y, we need to use the substitution property, where we replace a variable with what we solved for.

[tex]\tt Step~1:[/tex]

Let's solve for y first. Equation (1st one): 8x + 4y = 12. To isolate y, we can first subtract 8x from both sides, and then divide all terms by 4.

[tex]\tt 8x- (8x)+4y=12-(8x)\\4y=12-8x\\4y/4=y\\12/4=3\\-8x/4=-2x\\y=3-2x[/tex]

[tex]\tt Step~2:[/tex]

Then, we can solve for x. Let's take the second equation: 3x + y = 3. We take what we solved for in the previous step and plug it into this equation.

[tex]\tt 2x+(3-2x)=3\\2x+3-2x=3\\2x-2x=0\\3-3=0\\0=0\\x=x[/tex]

[tex]\large\boxed{\tt Our ~final~answer:(x,3-2x)}[/tex]

Both equations are also the same, so the solution = all real numbers for x.

[tex]\tt y=3-2x\\3-2x=3-2x[/tex]

Answer:

Answer has explained below.

Step-by-step explanation:

Consider the function is:

F(x) = 25x3 – 6x2 +7x -88

Differentiate with respect to x, we get

F’(x) = 25. 3x2 – 6.2x + 7

       = 75x2 – 12x +7

At x = 2, we have

F (2) = 25(2)3 – 6(2)2 + 7(2)-88

        =102

And f’(2) = 75(2)2 – 12 (2) +7

               =283

Now, calculate forward divided difference as:

xi + 1 = xi + h

        =2 + 0.25

        =2.25

F (xi + 1) = f (2.25) = 25 (2.25)3 – 6(2.25)2 +7(2.25) -88

                            =182.21

f’(2) = f(2.25) – f(2) / 0.25 = 182.21 – 102 / 0.25

                                             = 320.84

Єt = 283 – 320.8 / 283 = -13.36%

Now calculate backward divided difference:

Xi-1 = xi –h = 2 – 0.25 = 1.75

F(xi-1)= f(1.8) = 25 . (1.8)3 -6 (1.8)2 + 7 (1.8) – 88

                       = 50.96

F’(2) = f(2) – f(1.8) / 0.25 = 102 – 50.96 / 0.25 = 204.16

Єt = 283 – 204.16 / 283 = 27.86%

Finally, centered divided difference is obtain by inserting f(xi+1) and f (xi-1):

F’(2) = f(2.25) – f(1.8) /2 x 0.25 = 320.84 -50.96 / 0.5 = 539.68

Єt = 283 – 539.68 / 283 = -90.7%

Another angle will be 24+x

x+24+x=90

2x+24=90

2x=66

x=66/2=33

Now,

x= 33

x+24= 33+24= 57

The claim is that the mean amount of Walker Crisps eaten was significantly higher for the children who watched the sports celebrity- endorsed Walker Crisps commercial

2

The kind of test to use is a t -test because a t -test is used to check if there is a difference between means of a population

3

[tex]t = 3.054[/tex]

4

The p-value  is   [tex]p-value = P(Z > 3.054) = 0.0011291[/tex]

5

The conclusion is  

There is sufficient evidence to conclude that the mean amount of Walker Crisps eaten was significantly higher for the children who watched the sports celebrity- endorsed Walker Crisps commercial

The test statistics is  

Step-by-step explanation:

From the question we are told that

   The first sample size is  [tex]n_1 = 51[/tex]

    The first sample  mean is [tex]\mu_1 = 36[/tex]

    The second sample size is  [tex]n_2 = 41[/tex]

    The second sample  size is  [tex]\mu_2 = 25[/tex]

     The first standard deviation is  [tex]\sigma _1 = 21.4 \ g[/tex]

    The second standard deviation is  [tex]\sigma _2 = 12.8 \ g[/tex]

  The  level of significance is  [tex]\alpha = 0.05[/tex]

The  null hypothesis is  [tex]H_o : \mu_1 = \mu_ 2[/tex]

The  alternative hypothesis is  [tex]H_a : \mu_1 > \mu_2[/tex]

Generally the test statistics is mathematically represented as

    [tex]t = \frac{\= x_1 - \= x_2}{ \sqrt{ \frac{s_1^2}{n_1} + \frac{s_2^2}{n_2} } }[/tex]

=>   [tex]t = \frac{ 36 - 25}{ \sqrt{ \frac{ 21.4^2}{51} + \frac{ 12.8^2}{41} } }[/tex]

=> [tex]t = 3.054[/tex]

The  p-value is mathematically represented as

     [tex]p-value = P(Z > 3.054)[/tex]

Generally from the z table  

             [tex]P(Z > 3.054) = 0.0011291[/tex]

=>   [tex]p-value = P(Z > 3.054) = 0.0011291[/tex]

From the values obtained  we see that [tex]p-value < \alpha[/tex] so  the null hypothesis is rejected

Thus the conclusion is  

  There is sufficient evidence to conclude that the mean amount of Walker Crisps eaten was significantly higher for the children who watched the sports celebrity- endorsed Walker Crisps commercial

The value of the difference in the mean number of chips eaten can be used to test the hypothesis.

The correct responses are;

Reasons:

The given parameters are;

The amount of Walker Crisps potato chips children ate, based on commercial watched.

Celebrity endorsed food snack commercial mean, [tex]\overline x_1[/tex] = 36 g

Sample size that watched the celebrity endorsed commercial, n₁ = 51

Alternative food snack commercial mean, [tex]\overline x_2[/tex] = 25 g

Sample size that watched the other commercial = 41

Standard deviation, SD,  of the samples;

Sample that watched the celebrity endorsed commercial, SD₁ = 21.4 g

Sample that watched the other commercial, SD₂ = 12.8 g

Reasons:

1. The claim from the question is; The mean amount of Walker Crisp eaten was significantly higher for the children who watched the sports celebrity - endorsed Walker Crisps commercial.

The null hypothesis is, H₀; [tex]\overline x_1 = \overline x_2[/tex] (There is no difference in the mean)

The alternative hypothesis is, Hₐ; [tex]\overline x_1[/tex] > [tex]\overline x_2[/tex] (The mean of the amount of Walker Crisps eaten is significantly higher for the children that watched the sports celebrity-endorsed commercial)

2. Given that the aim of the study is to determine if the mean of the first

sample is higher than the mean of the second sample, the kind of test to

be performed is the test of the difference in the mean of the two samples

based on specified hypothesis, (one sample is higher), which is done using

a t-test, given that the population mean is not specified (unknown).

The kind of test to use is a t-test

3. The test statistic is given by Welch's Test for unequal variance as follows;

[tex]\displaystyle t = \mathbf{\frac{\overline x_1 - \overline x_2}{\sqrt{\dfrac{s_1^2}{n_1} +\dfrac{s_2^2}{n_2} } }}[/tex]

Which gives;

[tex]\displaystyle t = \frac{36- 25}{\sqrt{\dfrac{21.4^2}{51} +\dfrac{12.8^2}{41} } } = \frac{77500}{25379} \approx 3.054[/tex]

The test statistic, t ≈ 3.054

4. From the above test statistic and by finding, degrees of freedom, df as follows, the p-value can be found.

[tex]\displaystyle df = \mathbf{\frac{\left(\dfrac{s_1^2}{n_1} +\dfrac{s_2^2 \righ}{n_2} \right)^2}{\dfrac{1}{n_1 - 1} \cdot \left( \dfrac{s_1^2}{n_1} \right)^2 + \dfrac{1}{n_2 - 1} \cdot \left( \dfrac{s_2^2}{n_2} \right)^2}}[/tex]

Which gives;

[tex]\displaystyle df = \frac{\left(\dfrac{21.4^2}{51} +\dfrac{12.8^2 \righ}{41} \right)^2}{\dfrac{1}{51 - 1} \cdot \left( \dfrac{21.4^2}{51} \right)^2 + \dfrac{1}{41 - 1} \cdot \left( \dfrac{12.8^2}{41} \right)^2} \approx \mathbf{83.69}[/tex]

From the t-test table, we have the p-value of the result as follows;

The p-value is; 0.001 < P(t > 3.054) < 0.0025.

5. The conclusion that can be made is; Given that the p-value of the test

statistic is less than the given alpha value of 0.05, we reject the null

hypothesis, given that there is significant statistical evidence to show that

the mean amount of Walker Crisp eaten was significantly higher for the

children that watch the celebrity-endorsed Walker Crisps commercial.

Answer:

Step-by-step explanation:

Angle A equals 4x+8

Angle B equals 5x-b

and they are vertical angles.

If so, vertical angels are equal. You can set the expressions equal to each other, solve for x, and plug that value back in to solve for A.

4x+8=5x-b

add 3 to both sides

4x+11=5x

subtract 4x from both sides

11=x

Then plug x=11 into 4x+8.
