a) The mean income to 2 DP is £23714.28. b. If Deva's income is excluded, then the mean income will be £16,500.
<h3>What is addition?</h3>
The addition is one of the mathematical operations. The addition of two numbers results in the total amount of the combined value.
a.
Andy = £9500
Bevan = £25000
Cheryl = £11250
Elliott = £12750
Frankie = £29500
Grace = £11000
Deva = £72000
Total Income = £166,000
To get the mean Income, we will divide the total income by 6 which is the number of people.
= £166,000/7
= £23714.28
b. If Deva's income is excluded, there'll be 6 people left.
Total income = £99000
Mean income = £99,000/6
= £16,500

D. The y-intercept does not matter when figuring out when lines are perpendicular to each other. The slopes have to be the complete opposites of each other. That means that if one slope is negative, the other is positive, and you have to flip the numerator and denominator of a fraction. If it is a whole number, the new numerator would be 1 and that number would be the denominator
Answer:
B. 12x + 8
Step-by-step explanation:
2x + 5 + 4x - 1 + 2x + 5 + 4x - 1
<em>Combine like terms.</em>
6x + 5 - 1 + 2x + 5 + 4x + 1
8x + 5 - 1 + 5 + 4x - 1
12x + 5 - 1 + 5 - 1
12x + 10 - 1 - 1
12x + 10 - 2
<em>Subtract 2 from 10 to get 8.</em>
12x + 8
The perimeter of the rectangle is 12x + 8, which is B.
