Answer:
-4/5
Step-by-step explanation:
okay well first you have to make each fraction into improper fractions
2 1/2 going into 3/2 and -1 7/8 into -15/8
and then do keep change flip keeping the first fraction (3/2), changing the division sign into a multiplication sign, and flipping the numerator and denominator of -15/8 into 8/-15
3/2 × 8/-15 = 24/-30 = 4/-5
also
4/-5 = -4/5
Answer:
9 to 3
Step-by-step explanation:
Those who don't enjoy reading: 8+1=9
Those who don't enjoy playing video games: 1+2=3
Ratio is 9 to 3.
Answer:
40.5
Step-by-step explanation:
Since the centroid (the point of concurrency of the sides of a triangle) divides the 3 medians into the ratios from the point to the centroid to the centroid to the side into the ratio of 2:1. To find PK divide 27 by 2
27/2=13.5
Then add 27 and 13.5 to get KL
27+13.5=40.5
Considering the p-value of the test, it is found that the result has neither statistical nor practical significance, as it does not give sufficient evidence that the IQ is increases by 10 to 20 points.
<h3>What is the relation between the p-value and the conclusion of the test hypothesis?</h3>
Depends on if the p-value is less or more than the significance level:
- If it is more, the null hypothesis is not rejected.
- If it is less, it is rejected.
In this problem, the p-value is of 0.28, which is greater than 0.05, hence there is not enough evidence that the IQ increase is as stated, meaning that the result has neither statistical nor practical significance.

Answer:
in a relationship that maps elements from one set (the inputs) into elements from another set (the outputs), the usual notation for the ordered pairs is:
(x, y), where x is the input and y is the output.
In this case, the point where the arrow starts is the input, and where the arrow ends is the output.
a)
The ordered pairs are:
(28, 93)
(17, 126)
(52, 187)
(34, 108)
(34, 187)
b) The domain is the set of the inputs, in this case the domain is the set where all the arrows start, then the domain is:
{17, 28, 34, 52}
And the range is the set of the outputs, in this case the range is:
{93, 108, 126, 187}
c) A function is a relationship where the elements from the domain, the inputs, can be mapped into only one element from the range.
In this case, we can see that the input {34} is being mapped into two different outputs, then this is not a function.
d) We can remove one of the two ordered pairs where the input is {34},
So for example, we could remove:
(34, 108)
And then the relation would be a function.
