Answer:

Step-by-step explanation:

using elimination you can see every other answer is definitely wrong leaving you with just one which is 2UX

Answer 2

Answer:

2UX (your answer is correct)

Step-by-step explanation:

One way to define a parabola is as the set of points equidistant from the focus and directrix.

That means the distance from W to the directrix must be the same as the distance WU. Since the parabola is symmetrical and WU is parallel to the directrix, we have WU = UT = UX. So the double length WT is double the distance UX:

WT = 2UX

Tukey HSD Interpretation
Criterion: Interpret Tukey HSD results from SPSS output.
Data: Use your output from Problem Set 4.6.
Instructions: Identify where significant differences exist at the .05 level between the stress levels.

Answers

Answer:

The solution can be defined as follows:

Step-by-step explanation:

They also have a significant outcome in our instance. Its value of F is 1.773, with such a p-value of 0.212 achieved meaning (which is greater than the .05 alpha level). It means that the press with different levels of stress of the stress variable may not differentiate objectively.

Even so, we still do not know which one of the multiple mechanisms is significant. They realize the diff. To do just that, the results of the Tukey HSD test should be regarded.

HSD Tukey

Looking at the Multiple Correlations table below, you will see that mean values were created for the standard deviation among pairs of various stress varying concentrations (High - Low; High - Medium )

This can be seen on one-way ANOVA(1.773, p=.212), there's no statistically significant difference between the groups. A Tukey post hoc study has observed that the increase among medium and high stress is statistically significant, as well as the difference among low, medium, and high stress is important.

Which of the following best forms the figure shown?
2 angles that meet at an endpoint
2 rays that meet at an endpoint
2 lines that meet at an endpoint
2 line segments that meet at an
endpoint

Answers

Answer:

2 angles that meet at an endpoint

As per the image, we can say that 2 rays that meet at an end point.

Option 2 is correct.

What is a ray?

A ray is a part of the line having one fixed point and the other point does not have an end.

As per the image, we can say that 2 rays that meet at an end point.

Because 2 rays meet at a point and another side arrow is shown in image.

Hence, option 2 is correct.

V(x)
True or false ???

Answers

Answer:

The statement 'V(x) is a function'' is False.

Step-by-step explanation:

Let us make the table from the given mapping

x y

0 0

5 2

5 1

10 2

15 3

We know that a function is a relation where each input or x-value of the X set has a unique y-value or output of the Y set.

If we observe the table, it is clear that x = 5 is repeated twice. It means the input x = 5 is duplicated.

In other words, we can not have duplicated inputs as there should be only 1 output for each input.

Therefore, V(x) is not a function.

Hence, the statement 'V(x) is a function'' is False.

Mackenzie picks some apples.
She eats 3 apples.
Now she has 9 apples.
How many apples did Mackenzie pick to start?
A. 3 apples
B. 6 apples
C. 9 apples
D. 12 apples

Answers

Answer:

d.12

Step-by-step explanation:

its saying she ate 3 an now has 9. so you really add 3 to 9 an your answer is 12. in other words x=9+3 for your level of math. i'll be glad to help her with her home work for now if you would like me to.

Answer: Option D 12 apples

Step-by-step explanation:

SOOOO

She ate 3 apples and after that, she left with the 9 apples

They asked how many did Mackenzie pick.

SO its past tense

we have to add 3 apples that she just ate

so 9+3= 12 apples

I think your teacher is wrong because I think your teacher thought that she had 9 apples actually she has 9 apples after she just ate. So if it was before she has eaten the apples then it would be 6

Tell the teacher that she/he is wrong and give this explanation

I hope this helps you and your teacher

Harriet buys lunch at school every day. She always gets
pizza when it is available. The cafeteria has pizza about 80% of the time.

Harriet runs a simulation to model this using a random
number generator. She assigns these digits to the possible outcomes for each day of the week:

• Let 0 and 1 = no pizza available

• Let 2, 3, 4, 5, 6, 7, 8, and 9 = pizza available

The table shows the results of the simulation.

Group number
Random digits
1: 19223
2: 73676
3: 45467
4: 52711
5: 95592

Group number
Random digits
6: 68417
7: 82739
8: 60940
9: 36009
10: 38448

What is the estimated probability that Harriet will eat pizza for lunch
every day next week?

A. 7/10 = 70%
B. 4/10 = 40%
C. 5/10 = 50%
D. 0/10 = 0%

Answers

The estimated probability that Harriet will eat pizza for lunch every day next week is 5/10 = 50%

How to determine the probability?

The simulation is represented as:

0 and 1 represents when pizza is not available2 to 9 represents when pizza is available

The above means that the simulation that represents when she eats pizza for lunch must have all its digits to be from 2 to 9.

The results that represent eating pizza for lunch are:

73676 45467 95592 82739 38448

The count of the result is 5.

Hence, the probability is 5/10 = 50%

3/3 = 1

Step-by-step explanation:

The slope formula is..

Pick two formulas. Let's do (-5, -2) and (-2, 1)

x1 y1 x2 y2

(-5, -2) (-2, 1)

[tex]\frac{1-(-2)}{-2-(-5)}[/tex] = [tex]\frac{3}{3}[/tex] = 1

It'll work the same thing for (-2, 1) and (1,4)...

3/3 or 1 is a pattern between the points.

Find the slope of the line.

Answers

The slope is 1/3 because slope is rise over run so you go up one unit and go right three units.

Answer:

The slope is 1/3

Step-by-step explanation:

Slope is rise over run. Starting from the point (1,-4), the line moves up one unit (rise=1) and then 3 units to the right (run=3) to get to the point (4,-3). Therefore rise over run, or the slope, is 1/3.
