Answer:
The 3rd one again
Step-by-step explanation:
(a+−2)(8
+−5a+3)
=(a)(8)+(a)(−5a)+(a)(3)+(−2)(8)+(−2)(−5a)+(−2)(3)
=8
−5+3a−16+10a−6
=8−21+13a−6
hope this helped:)
Surface area of cylinder = 2πr² + 2πrh
r=14/2=7 cm
h=22 cm
Surface area of cylinder = 2*π*7² + 2π*7*22 = 98π + 308π = 406π ≈ 3.14*406 =
=<span>1274.84 </span>≈ 1275 cm²
Answer is A. 1275 cm².
I think it’s 36
Explanation if all parts are equal then since there are 9 parts in total then each part is 4 grams and since there’s 3 adhesive parts it’s 12 grams in total and 12x3 = 36 hope this helped
ANSWER
{},{1}
EXPLANATION
The given set has one element. So it has
subsets.
These are,
{} and {1}.
That is, the null set and the set itself.
Remember that, the null set is a subset of every set and every set is a subset of itself.
Step-by-step explanation:
The regression equation is correctly written as:
log(rent) = β₀+β₁log(pop)+β₂log(avginc)+β₃pctstu+μ
1. this question requires us to State the null hypothesis that size of the student body relative to the population has no ceteris paribus effect on monthly rents.
<u>null hypothesis</u>
H₀ : β₃ = 0 (no effect exists)
<u>alternative that there is an effect.</u>
H₁ : β ≠ 0
2.
Due to increased demand when population is increased, the higher the number of people living in the city then there is a great likelihood that rent would increase. β1 will therefore be positive, all things being equal.
as average income rises, so also would rent as the people would have more money and therefore there would be increased demand for housing. This increase in demand would then cause a surge in the price of rent. β₂ would therefore be positive .
the last question you posted is incomplete so i was unable to go ahead with it.
