Answer:
15
Step-by-step explanation:
The difference between consecutive integers is 1.
The difference between consecutive odd integers is 2.
Let the smallest odd integer be x.
Then the next greater one is x + 2. The greatest one is x + 4.
"3 times the first" is 3x
"twice the third" is 2(x + 4)
"3 times the first of three consecutive odd integers is 3 more than twice the third"
3x = 2(x + 4) + 3
3x = 2x + 8 + 3
x = 11
The smallest integer is 11.
x + 4 = 11 + 4 = 15
The greatest one is 15.
Answer:
d. Twenty-five cars are randomly selected with the new transmission and 25 with the old transmission.
Step-by-step explanation:
A hypothesis test on the difference between the means must satisfy the following conditions
1) the samples must be randomly selected
2) each sample must have a known standard deviation
3) the samples must be independent
4) the samples must be from normal distribution
Hence only part d gives the right answer.
2x+y=8 is the equation perpendicular to x-2y=8.
Answer: I x^2 y^3 z
Step-by-step explanation:
This is the one most simplified. I’ll tell you why the others are incorrect.
F) 3^5 x^2 can be simplified. 3^5= 243. The simplified answer would be 243 x^2
G) (5y)^3= 125y^3
H) a^0 b (^0= 1 always) -> ab
Hope this helps!
