Which direction would the graph of y=-|X|+ 9 open?

Answer:

The responses can be defined as follows:

Step-by-step explanation:

Given:

[tex]H_o : \mu_1 = \mu_2\\\\H_a : \mu_1 < \mu_2[/tex]

Testing the hypothesis:

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

   [tex]=\frac{(22.41-27.75)}{\sqrt{(\frac{1.27^2}{40}+\frac{2.64^2}{24})}}\\\\=-9.29\\\\[/tex]

[tex]a=0.01[/tex]

critical value [tex]Z(0.01)=-2.33[/tex] (using the standard normal table)

[tex]Z=-9.29<-2.33[/tex] so, we reject [tex]H_o[/tex].

Using the t-distribution, it is found that since the test statistic is greater than the critical value for the right-tailed test, there is sufficient evidence for one to claim that, in general, rugby players have a higher BMI than the multisport men.

At the null hypothesis, it is tested that rugby players do not have a higher BMI than the multi-sport men, that is, the subtraction of the means is not greater than 0, hence:

[tex]H_0: \mu_R - \mu_M \leq 0[/tex]

At the alternative hypothesis, it is tested if they have a higher BMI, that is:

[tex]H_1: \mu_R - \mu_M > 0[/tex]

We have the standard deviation for the samples, hence, the t-distribution is used.

The standard errors are given by:

[tex]s_M = \frac{1.27}{\sqrt{40}} = 0.2008[/tex]

[tex]s_R = \frac{2.64}{\sqrt{24}} = 0.5389[/tex]

For the distribution of differences, the mean and the standard error are given by:

[tex]\overline{x} = \mu_R - \mu_M = 27.75 - 22.41 = 5.34[/tex]

[tex]s = \sqrt{s_M^2 + s_R^2} = \sqrt{0.2008^2 + 0.5389^2} = 0.5751[/tex]

The test statistic is given by:

[tex]t = \frac{\overline{x} - \mu}{s}[/tex]

In which [tex]\mu = 0[/tex] is the value tested at the null hypothesis.

Hence:

[tex]t = \frac{\overline{x} - \mu}{s}[/tex]

[tex]t = \frac{5.34 - 0}{0.5751}[/tex]

[tex]t = 9.29[/tex]

Using a t-distribution calculator, for a right-tailed test, as we are testing if the mean is greater than a value, with a significance level of 0.05 and 40 + 24 - 2 = 62 df, the critical value is of [tex]t^{\ast} = 1.67[/tex]

Since the test statistic is greater than the critical value for the right-tailed test, there is sufficient evidence for one to claim that, in general, rugby players have a higher BMI than the multisport men.

Answer:

0.0000024

Step-by-step explanation:

Given :

2.4 x 10-6

10^-6 = 0.000001

2.4 * 10^-6 = 2.4 * 0.000001

2.4 * 10^-6 = 0.0000024

Hence, in standard form : 0.0000024

Answer:

Step-by-step explanation:

The answer would be the first option because it’s starting at 4.5, and if you subtracted 2.5, you would get the answer of 2, and that’s what the first option shows. Hope this helps!

Slope = [tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]

So taking 2 points (0,0) and (60,120)

we have slope = (120-0)/(60-0) = 120/60 = 2

general equation of linear graph is y=mx+b with m be the slope

so y=2x+b

Now to find b, just plug any point of the graph in, such as (0,0)

so we get something like 0=2(0) + b => b=0

So your equation is y=2x

X = 39[tex]ft[/tex]

Answer:false

Step-by-step explanation:120 tens would be 1200

The number 12,000 does not equal 120 tens. Thus, it is false.

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.

The expression is given below.

12,000 = 120 tens

Simplify the equation, then we have

12,000 = 120 x 10

12,000 ≠ 1,200

The given equation is false.

Translation is usually movements like up, down, left, right.

Dilation is when one shape is bigger/smaller than the other, but still congruent.

Reflections are usually done over an axis (x or y), and don't change the degree at which a shape is turned. From looking at the triangles, you can see that one triangle was turned clockwise.

Answer:

Both companies claim that their batteries last longer than the average alkaline battery is true .

Step-by-step explanation:

Both companies claim that their batteries last longer than the average alkaline battery  is true because most of the batteries of these companies  did passed the test to last longer.

As we can project from that table given that around 77% Energized batteries passed the test and around 67% powered cell  batteries passed the test.

hence we can also inferred from here that Energized batteries are more consistent.

Answer: B ,I just completed the assignment

AB=CD is not always true. Therefore, option B is the correct answer.

From the given construction, we need to find which conclusion is not always true.

A perpendicular bisector is defined as a line or a line segment that divides a given line segment into two parts of equal measurement. 'Bisect' is the term used to describe dividing equally. Perpendicular bisectors intersect the line segment that they bisect and make four angles of 90° each on both sides.

Here, AB⊥CD.

Since CD is the perpendicular bisector of AB.

AE=EB and CE=DE

AB=CD is not always true. Therefore, option B is the correct answer.
