Answer:

x = -7.5

y = 5.5

Step-by-step explanation:

You weren't very clear in what you wanted, however if you are asking where the line touches, it hits (-7.5, 0) on the x-axis and (0,5.5) on the y-axis.

Hope this helps! Please mark as brainliest ;)

Last week Tina are in $2.50 less than twice what earned how much did Tina earn last week if add earn $6.50?

Hatshy [7]

Answer:

Tina earned $11.5

Step-by-step explanation:

From the question, we are told that Tiana earns 2.50 less than twice what is earned by Add

let us have x as what is earned by Add

Thus, we have what is earned as 2x-2.5

Now Add, earned 6.50, so we want to know what Tina earned

That would be;

2(6.5) - 2.5

= 13-2.5

= 10.5

56. A track coach recorded all runners' times for the 200-meter dash and

ddd [48]

Considering that outliers will be disconsidered, the correct statement is:

The coach can use the Interquartile Range to summarize the runners' times.

<h3>What is the Interquartile Range(IQR) of a data-set?</h3>

It is the values of a data-set that are between the 25th percentile and the 75th percentile, that is, the middle 50% of the values. It's advantage in certain situation is that it disconsiders outliers.

In this problem, the best way to summarize the times is disconsidering outliers, hence the Interquartile Range is used, as it indicates how close all runners' times were to each other.

A dice game lets you roll 2 6 sided disc and find the sum of the numbers. A 12 wins 100 dollars, 10 or 11 wins 50 dollars, a 2 w

Advocard [28]

Answer:

Step-by-step explanation:

A two 6 sided die is rolled

Sample space would be (1,1)...(1,6)....(6,1)....(6,6)

Let x be the sum obtained

X can take values as 2 or 3 ....12

P(x=12) = P(6,6) =1/36

P(x=10 or 11) = P{(5,5)(5,6) (6,5) (4,6)(6,4)}=5/36

P(2) =P(1,1) = 1/36

For other outcomes no payment

Thus we can list this as

Sum 2 3 4 5 6 7 8 9 10 or 11 12

Prob 1/36 5/36 1/36

Gain 3 0 0 0 0 0 0 0 50 100

E(gain) 3/36 0 0 0 0 0 0 0 250/36 100/36

E(gain) = total= 353/36

Cost of game = 6

E(outcome) = E(gain -6) = E(gain)-6 = 353/36 -6

= 3.806

Find the missing probability.

Westkost [7]

The value of the missing probability is:

P(A) = 1/5

So the correct option is D.

<h3>How to find the missing probability?</h3>

First, we know that:

P(A∩B) = probability that events A and B are true = 3/100

And we also know that:

P(B|A) = probability that event B is true given that event A is true = 3/20

Here we have the rule:

P(A∩B) = P(B|A)*P(A)

Replacing the first two:

3/100 = (3/20)*P(A)

Solving for P(A), we get:

(3/100)*(20/3) = 1/5 = P(A).

So we conclude that the correct option for the missing probability is the one in option D.
