Type I error is We conclude that the mean is not 34 years when it really is 34 years. The correct option to this question is C.

Rejecting the null hypothesis when it is in fact true is a Type I mistake. It entails drawing conclusions about outcomes that are statistically significant when, in fact, they were just the consequence of chance or unrelated causes.

The significance level you select (alpha or ) determines the likelihood that you will make this mistake. You determined that figure at the start of your research to determine the statistical likelihood of getting your results (p-value).

The typical significance level is 0.05 or 5%. If the null hypothesis is accurate, your results only have a 5% chance or less of occurring.

In Listening 1.2, Miley Cyrus’ Wrecking Ball, identifying the difference in Verse, Chorus, and Bridge is quite easy.

The verse part of the song is the section that is generally sung in a lower key and can be regarded as the storytelling aspect of the song. The musical form or structure of the song, “Wrecking Ball” impacts the song's repeatability as it is designed to create a catchy, repeating theme that sticks in the listener's head.

Additionally, the predictability of the song's structure makes it easier for DJs to mix songs in clubs or at parties. My aesthetic response to the song is a bit mixed. This structure makes the song more engaging, and it is easy to get lost in the emotion of the song. Additionally, the repeating theme of the chorus makes it easier for the listener to sing along.

The linear system have y = -6x+2 and -12x - 2y = -4 have infinite number of solutions.

Two or more expressions with an Equal sign is called as Equation.

The given system of linear equations are y = -6x+2 and -12x - 2y = -4

To solve this system, we can substitute the expression for y from the first equation into the second equation, as follows.

-12x - 2y = -4

substitute y = -6x + 2 from first equation

-12x - 2(-6x + 2) = -4

Distribute the negative sign

-12x + 12x - 4 = -4

0 = 0

The equation 0 = 0 is a true statement, which means that the system has infinitely many solutions.

Hence, the linear system have y = -6x+2 and -12x - 2y = -4 have infinite number of solutions.

Answer:

y=2x+4

Step-by-step explanation:

2 is the slope, you can see that with rise over run. 4 is the y intercept

Answer:

y=2x+4

Step-by-step explanation:

Look at the y-axis if the point that touches the y-axis is 4

Then the slope is 2

you go down 2 which is -2 (Since down is negative)

and you go left 1 which is -1 (Since left is negative)

now the equation looks like this:

y=-2/-1x+4

Simplify: (negative and negative cancel each other out making it positive)

y=2x+5

The mean yields of the control group and the treatment group are:Control group: Mean = 0.9Treatment group: Mean = 1.1b) The experimental difference of the means can be found by:

Experimental difference of the means = Treatment group mean - Control group mean= 1.1 - 0.9= 0.2

Therefore, the experimental difference of the means is 0.2.c) The following double dot plot shows the bone density of the control group and the treatment group:

d) Based on the given data, we can conclude that the vitamin supplement does have a significant effect on bone density. This is because the experimental difference of the means is 0.2, which indicates that the treatment group had a higher bone density than the control group.

The points A, B, and B form a right angle at the point B and the slope of AB is the ratio of BC to AB.

Reasons:

From the diagram, the coordinates of A = (-2, -5)

The length of AB = 5

The length of BC = 10

Solution:

Point B is along the same horizontal line as point A, therefore, given that

AB = 5 units, point B is 5 unite to the right of point A at the coordinate (-2 + 5, -5) = (3, -5)

The coordinates of point \(\underline{B = (3, \ -5)}\)

The point C is on the same vertical line as the point B, therefore, given that

BC = 10, the coordinates of point C is the x-coordinates of B and 10 plus the

y-coordinates of the point B, which gives;

C = (3, -5 + 10) = (3, 5)

The coordinates of point \(\underline{C = (3, \, 5)}\)

The slope, m, of the line BC is found as follows;

\(\displaystyle m =\mathbf{ \frac{Length \ of \ BC}{Length \ of \ AB} }= \frac{10}{5} =2\)

The equation of the line BC is; y - 5 = 2·(x - 3)

Which gives;

y = 2·x - 6 + 5 = 2·x - 1

y = 2·x - 1

The point D is the point where the x-coordinate of a  point on the line is 0

Therefore, y-value at D  is y = 2 × 0 - 1 = -1

Answer:

x = 46°

Step-by-step explanation:

Angles on a straight line sum to 180°.

Therefore, the interior angle of the triangle that forms a linear pair with the exterior angle marked 130° is:

⇒ 180° - 130° = 50°

The interior angle of the triangle that forms a linear pair with the exterior angle marked 96° is:

⇒ 180° - 96° = 84°

The interior angles of a triangle sum to 180°. Therefore:

⇒ 50° + 84° + x = 180°

⇒ 134° + x = 180°

⇒ 134° + x - 134° = 180° - 134°

⇒ x = 46°

Therefore, the size of angle x is 46°.

The most appropriate hypothesis test to determine if there is evidence to support the claim that the proportion of people who smoke is less than 22.5% is a lower-tailed z-test.

To determine if there is evidence to support the claim that the proportion of people who smoke is less than 22.5%, we need to perform a hypothesis test. Since we are dealing with proportions, we use the z-test for proportions.

The null hypothesis (H0) is that the proportion of people who smoke is equal to 22.5%. The alternative hypothesis (Ha) is that the proportion of people who smoke is less than 22.5%. We set the level of significance (α) to a predetermined value, usually 0.05.

We then collect a random sample of individuals and calculate the sample proportion who smoke, denoted by p-hat. We also calculate the standard error of the sample proportion, denoted by SE(p-hat), using the formula sqrt[p(1-p)/n], where p is the hypothesized proportion and n is the sample size.

Using these values, we calculate the test statistic, which is given by (p-hat - p) / SE(p-hat), where p is the hypothesized proportion. We compare the test statistic to the critical value from the standard normal distribution, which is found using the level of significance and the appropriate tail (in this case, lower-tailed).

If the test statistic is less than the critical value, we reject the null hypothesis and conclude that there is evidence to support the claim that the proportion of people who smoke is less than 22.5%. Otherwise, we fail to reject the null hypothesis and conclude that there is not enough evidence to support the claim that the proportion of people who smoke is less than 22.5%.

Solution:

Given:

To get angle x, we use the trigonometric ratio of tangent.

Hence,

Answer:

\(\displaystyle{f^{-1}(x)=\dfrac{x}{7}-\dfrac{3}{7}}\)

Step-by-step explanation:

Swap f(x) and x position of the function, thus:

\(\displaystyle{x=7f(x)+3}\)

Then solve for f(x), subtract 3 both sides and then divide both by 7:

\(\displaystyle{x-3=7f(x)}\\\\\displaystyle{\dfrac{x}{7}-\dfrac{3}{7}=f(x)}\)

Since the function has been inverted, therefore:

\(\displaystyle{f^{-1}(x)=\dfrac{x}{7}-\dfrac{3}{7}}\)

And we can prove the answer by substituting x = 1 in f(x) which results in:

\(\displaystyle{f(1)=7(1)+3 = 10}\)

The output is 10, now invert the process by substituting x = 10 in \(f^{-1}(x)\):

\(\displaystyle{f^{-1}(10)=\dfrac{10}{7}-\dfrac{3}{7}}\\\\\displaystyle{f^{-1}(10)=\dfrac{7}{7}=1}\)

The input is 1. Hence, the solution is true.

a) 214 in base-five is 1324.

b) 62 in base-five is 222.

c) 8 in base-five is 13.

d) 95 in base-five is 340.

a) To determine the base five representation of 214, we need to   find the largest power of five that  is less than or equal to  214.

In this case, 125 (5³) is the largest power of five   that is less than 214.

Now, we divide 214 by 125 -  

214 ÷ 125 = 1 remainder 89

Next, we divide the remainder, 89, by the next lower power of five, which is 25 (5²) -  

89 ÷ 25 = 3 remainder 14

Finally, we divide the remaining 14 by the lowest power of five, which is 5 itself -  

14 ÷ 5 = 2 remainder 4

Therefore, the base-five representation of 214 is 1324 in base-five.

b) Following the same steps as above -  

62 ÷ 25 = 2 remainder 12

12 ÷ 5 = 2 remainder 2

Hence,  the base-five representation of 62 is 222 in base-five.

c) 8 ÷ 5 = 1 remainder 3

this menas that  the base-five representation of 8 is 13 in base-five.

d) Following the same steps as above -  

95 ÷ 125 = 0 remainder 95

95 ÷ 25 = 3 remainder 20

20 ÷ 5 = 4 remainder 0

Hence, the base-five representation of 95 is 340 in base-five.
