Answer:
the slope is 4/5
Step-by-step explanation:
well the slope formula is the following:
m= (change in y)/(change in x)
let's take the two following points
(-3,0) and (2,4) so
so
change in y =
change in x =
so
m=4/5
The question says there are 7 employees and there are only 6 salaries. Is there one number missing? I'll continue with 6 numbers, but if there are 7 listed in the question, then my answers will be wrong.
Mean is the average of a given set of numbers. Find the median by adding all numbers in the set & dividing by the quantity of numbers in the set.
Median is the middle number of a given set of numbers. Put list in chronological order and take the center number. In a case of even numbers, average the two center numbers.
CURRENT MEAN (Average)
653 + 667 + 780 + 872 + 885 + 954=
4811
4811 ÷ 6 employees= 801.83
CURRENT MEAN (Middle #)
Since there are 6 numbers, find the average of the two middle numbers
653 667 780 872 885 954
780 + 872= 1652 ÷ 2= 826
NEW MEAN
695 + 667 + 780 + 872 + 885 + 954=
4853
4853 ÷ 6= 808.83
NEW MEDIAN
667 695 780 872 885 954
780 + 872= 1652 ÷ 2= 826
No change in median
ANSWER: The mean goes from 801.83 up to 808.83. The median remains the same at 826.
Hope this helps! :)
The probability that a home selected at random has at least one feature (either a garage, a pool, or both features) is 0.95.
<h3>What is probability?</h3>
It is defined as the ratio of the number of favorable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.
We have:
Event A: 90% of homes for sale have garages
Event B: 15% have swimming pools
Event(A∩B): 10% have both features.
P(A or B) = P(A) + P(B) + P(A∩B)
= 0.90+0.15 - 0.10
= 0.95
Thus, the probability that a home selected at random has at least one feature (either a garage, a pool, or both features) is 0.95.

Answer:
15
Problem:
Given that a*b = 2ab - 3b. Determine 2*(3*5)
Step-by-step explanation:
First we find 3*5 using rule a*b = 2ab - 3b.
3*5=2(3)(5)-3(5)
3*5=30-15
3*5=15
Now we are left with 2*15 in which we will still use the rule a*b=2ab-3b.
2*15=2(2)(15)-3(15)
2*15=60-45
2*15=15
Therefore, 2*(3*5)=15.
