Answer:
10 and 16, x+(x+6)=26
Step-by-step explanation:
Michelle has an age we don't know, so we put her age as x.
Yogi is 6 years older than her, so her age is x+6
Michelle=x
Yogi=x+6
we know both their ages equal 26. so we set it up as
x+(x+6)=26
combining like terms we get
2x+6=26
subtract 6 from both sides
2x=20
divide both sides by 2
x=10
now that we have the value for x, we plug it into their original ages
Michelle is 10, because her age is just x.
Yogi is 16, because her age is x+6
Answer:
3) One-sided,compare two populations
Step-by-step explanation:
A manufacturer wants to investigate the whether there is an increase in the mean gas mileage of mid-sized sedan having new type of tire compared to mean gas mileage of mid-sized sedan not having new type of tire.
So, there are two populations :
population 1 : mid-sized sedan having new type of tire.
population 2 : mid-sized sedan not having new type of tire.
So, two populations are being compared.
Also, A manufacturer is investigating whether there is an increase in mean gas mileage.The alternative hypothesis will be right tailed and so, this corresponds to one sided test.
Answer:
14
Step-by-step explanation:
21 divided by 1.5 from the 3/2 you get 14
Answer:
x ≈ 28.2
Step-by-step explanation:
Δ CAB ≅ Δ CDE then corresponding sides are in proportion, that is
= 
, substitute values
= 
= 
( cross- multiply )
28x = 18.7(14 + x) ← distribute
28x = 261.8 + 18.7x ( subtract 18.7x from both sides )
9.3x = 261.8 ( divide both sides by 9.3 )
x ≈ 28.2 (to the nearest tenth )
