Ellianna made a scatter plot that showed a positive association and had one outlier. Write a possible scenario for Ellianna's scatter plot
Hint
o
The scatter plot could show test scores based on number of student absences. The outlier could be a student with high test scores who has many
absences,
The scatter plot could show the amount of pay workers at a factory received based on the number of years they have worked at the factory. The
outlier could be someone who is very skilled and has learned her job quickly.
The scatter plot could show the amount of weight that someone gains based on the number of calories that they consume. The outlier could be
someone who eats few calories and does not gain much weight.
The scatter plot could show the amount of weight that a elephant gains based on its age. The outlier could be an adult elephant that weighs more
than a baby elephant.

Step-by-step explanation:

Some values of the linear function f are given in the table shown. What is the value of f(100)?

Answers

Answer:

f(100) = 160.

Step-by-step explanation:

Linear function:

The equation of a linear function has the following format:

[tex]y = mx + b[/tex]

In which m is the slope(how much f(x) changes when x changes by 1) and b is the y-intercept(value of f(x) when x = 0).

Finding the slope:

Suppose we have two points. The slope is the change in the output divided by the change in the input.

In this question, we have points (45,50) and (60,80).

Change in the output: 80 - 50 = 30

Change in the slope: 60 - 45 = 15

Slope: 30/15 = 2

[tex]y = 2x + b[/tex]

Point (45,50)

This means that when [tex]x = 45, y = 50[/tex]. We use this to find the value of b.

[tex]y = 2x + b[/tex]

[tex]50 = 2(45) + b[/tex]

[tex]b = -40[/tex]

[tex]y = 2x - 40[/tex]

With y = f(x)

What is the value of f(100)?

This is y when x = 100. So

[tex]f(100) = 2(100) - 40 = 200 - 40 = 160[/tex]

f(100) = 160.

For a sample of 9 automobiles, the mileage (in 1000s of miles) at which the original front brake pads were worn to 9% of their original thickness was measured, as was the mileage at which the original rear brake pads were worn to 9% of their original thickness. The results were as follows: Car Rear Front 1 40.6 32.5 2 35.4 27.1 3 46.6 35.6 4 47.3 35.6 5 38.7 30.3 6 51.2 41.1 7 50.6 40.7 8 45.9 34.3 9 47.2 36.5 Send data to Excel Part: 0 / 20 of 2 Parts Complete Part 1 of 2 (a) Construct a 99.5% confidence interval for the difference in mean lifetime between the front and rear brake pads.

Answers

Answer:

CI =[- 4.588; 15.4]

Since the calculated value of t= 4.244 falls in the critical region so we reject H0 and conclude that we are not confident that the mean difference in lifetime between front and rear brake pads is 99.5%

Step-by-step explanation:

The given data is

Car Rear Front d= rear- front

1 40.6 32.5 8.1

2 35.4 27.1 8.3

3 46.6 35.6 11

4 47.3 35.6 11.7

5 38.7 30.3 8.4

6 51.2 41.1 10.1

7 50.6 40.7 9.9

8 45.9 34.3 11.6

9 47.2 36.5 10.7

∑ = 89.8

Let the hypotheses be

H0: ud= 0 against the claim Ha: ud ≠0

The degrees of freedom = n-1= 9-1= 8

The significance level is 0.05

The test statistic is

t= d`/sd/√n

The critical region is ║t║≤ t (0.025,8) = ±2.306

Sd= 7.05434553

d`=∑d/n= 89.8/9= 9.978

Therefore

t= d`/ sd/√n

t= 9.978/ 7.054/√9

t= 4.244

1) Since the calculated value of t= 4.244 falls in the critical region so we reject H0 and conclude that we are not confident that the mean difference in lifetime between front and rear brake pads is 99.5%

2) the confidence interval for the difference of two samples can be calculated by

d ` ± td sd/√n

9.978 ±2.306* 7.054/√9

Step-by-step explanation:

p = 40% = 0.4 ; q = 1-p = 1 - 0.4 = 0.6

n = 20 ; x = 10

P(x = x) = nCr * p^x * q^(n-r)

P(x = 10) = 20C10 * 0.4^10 * 0.6^10

P(x = 10) = 184756 * 0.0001048576 * 0.0060466176

P(x = 10) = 0.11714155

P(x = 10) = 0.1171

Question 11
A card game is being played and the 5 of spades and 10 of clubs are drawn. In order to win the
hand, the next card must be higher than the highest card already on the table. Assuming the
game is played with a single deck, what is the chance that the next card drawn will win the
hand? (An ace has a value of 1.)
A.3%
B.12%
I
C.24%
D.25%

Answers

Answer:

24%

Step-by-step explanation:

trust me and get blessed

The probability of drawing a card that could win the hand and actually winning the hand is 12%.

Option B is the correct answer.

What is probability?

It is the chance of an event to occur from a total number of outcomes.

The formula for probability is given as:

Probability = Number of required events / Total number of outcomes.

Example:

The probability of getting a head in tossing a coin.

P(H) = 1/2

We have,

There are 50 cards left in the deck after the 5 of spades and 10 of clubs are drawn since there are 4 suits with 13 cards each, and 2 of those cards have already been drawn.

Out of the remaining 50 cards, there are 16 cards that could win the hand: the 9 remaining cards higher than the 10 of clubs in any suit, and the 6 remaining cards in the spade suit (since the 5 of spades is already on the table).

Therefore, the probability of drawing a card that could win the hand is 16/50, which simplifies to 8/25. This is approximately 0.32 or 32%.

However, we need to subtract the probability of drawing the 5 of clubs, 10 of spades, or any of the 8 remaining cards that would not win the hand.

The probability of drawing one of these cards is 10/50, which simplifies to 1/5 or 20%.

The probability of drawing a card that could win the hand and actually winning the hand is:

(16/50) x (1/5)

= 0.32 - 0.2

= 0.12 or 12%.

Thus,

The probability of drawing a card that could win the hand and actually winning the hand is 12%.
