Answer:24+4x
Step-by-step explanation:
a=5. PHOTO
b=7. PHOTO
a1=5+x. FRAME
b1=7+x. FRAME
Pf=2*(a1+b1)
Pf=2*(5+x+7+x)
Pf=2*(12+2x)
---------Pf=24+4x. - - - - - - PERIMETER OF FRAME
28 should be added to make it a sub of zero
Answer:
8x^{3}
Step-by-step explanation:
By the laws of exponents we have to multiply each term in the parenthesis by the exponent on the outside:
(2x)^{3} would be equal to = 8x^{3}
Another way we could write would be (2x)(2x)(2x) = 8x^{3}
The second one is the same, just fill in as 8 and 3
Answer:
420 Mile's.
Step-by-step explanation:
First you figure out the unit rate by dividing 360 by 6 which is 60. So that's 60 miles per hour. Now multiply 60 by 7 to find out how many miles she will drive in 7 hours. When you multiply you get 420.
Answer:
True
Step-by-step explanation:
Type I and Type II are not independent of each other - as one increases, the other decreases.
However, increases in N cause both to decrease, since sampling error is reduced.
A small sample size might lead to frequent Type II errors, i.e. it could be that your (alternative) hypotheses are right, but because your sample is so small, you fail to reject the null even though you should.
