I think the answer would be conditional probability. It is a type of probability that the focus is on a certain group and taking a sample from it randomly. It is the probability of a certain event basing on the occurrence of an event that happens previously.<span />

The high temperature on Friday was 8 degrees above zero. The low temperature was 3 degrees below zero. Which expression gives th
olga_2 [115]

Using the mean concept, the expression that gives the average of the low and high temperatures is:

(-3 + 8)/2.

<h3>What is the mean?</h3>

The mean of a data-set is given by the <u>sum of all observations in the data-set divided by the number of observations</u>.

In this problem, the two observations are -3 and 8, hence their average is given by:

(-3 + 8)/2.

HELP asap plz<br><br> Solve 2y^2 – 3y = 2
Veseljchak [2.6K]
Your answer is y = -1/2 and y = 2

To solve this quadratic we first need to subtract 2 from both sides to set it equal to 0, which gives us 2y² - 3y - 2 = 0

Then we just need to factorise it:

2y² - 3y - 2 = 0
(2y + 1)(y - 2) = 0

Now we can set each bracket equal to 0 and solve for y:
2y + 1 = 0
2y = -1
y = -1/2

y - 2 = 0
y = 2

I hope this helps! Let me know if you have any questions :)

(20 points) <br><br> Find x:<br><br> (x−2)^2=25<br><br> pls show steps so I understand lol
egoroff_w [7]

Answer:

(-3, 7)

Step-by-step explanation:

ok so first take the square root of both sides, so you get (x-2)=5, since the square root gets rid of the power, and the square root of 25, is 5, and since we did a square root, we also have to do the - + thing, so the equation really is now x-2=(+-)5

subtract 2 from both sides, and you get x=(+-)5+2

Solving for x we get -5+2=-3

and also

5+2=7 since there was a positive, and a negative 5.

therefore x would equal (-3, 7)

hope this helps, please mark as brainliest.
