Answer:
A) 4
B) Mode is 5
C) 10.5
Step-by-step explanation:
A) 62+x/12
(62 + x) ÷ 12 = 5.5 ×12
62 + x = 66
×= 66-62
×=4
B) mode is the highest occuring no which is 5
C) mean has been given as 5.5; mean plus mode= 10.5
Answer:
<u>The correct answer is A. - 11 square root of 7.</u>
Step-by-step explanation:
We have the expression 2 √28 - 5 √ 63 and we have to find and equal expression.
Let's simplify it:
2 √28 - 5 √ 63
2 √7 * 4 - 5 √ 9 * 7 (28 is also equal to 7 * 4 and 63 is equal to 9 * 7)
2 * 2 √7 - 5 * 3 √ 7
4 √7 - 15 √7
- 11 √7
<u>The equal expression is A. - 11 square root of 7.</u>
Answer:
-3
Step-by-step explanation:
-3 is the slope y=mx + b m is -3
Answer:
See proof below
Step-by-step explanation:
Let x,y be arbitrary real numbers. We want to prove that if x≠y then f(x)≠f(y) (this is the definition of 1-1).
If x≠y, we can assume, without loss of generality that x<y using the trichotomy law of real numbers (without loss of generality means that the argument in this proof is the same if we assume y<x).
Because f is strictly increasing, x<y implies that f(x)<f(y). Therefore f(x)≠f(y) because of the trichotomy law, and hence f is one-to-one.
