Answer:
$196
Step-by-step explanation:
Step one
given data
We are told that Noel bought a printer for $10 less than half its original price
let the original price be x
hence Noel paid = x/2-10= 88
Step two
amount paid= x/2-10= 88
Collect like terms
x/2= 88+10
x/2= 98
cross multiply
x=196
Hence the original price is $196
He uses 1/5 OF 5/6 of a yard. That "of" is very important, because it indicates that, to find the answer, you multiply the two together.
That being said (1/5) times (5/6) =5/30, which can be reduced to 1/6 yds to make the frame
Answer:
Kindly check explanation
Step-by-step explanation:
Given that :
The hypothesis :
H0 : σ²= 47.1
H1 : σ² > 47.1
α = 5% = 0.05
Population variance, σ² = 47.1
Sample variance, s² = 83.2
Sample size, n = 15
The test statistic = (n-1)*s²/σ²
Test statistic, T = [(15 - 1) * 83.2] ÷ 47.1
Test statistic = T = [(14 * 83.2)] * 47.1
Test statistic = 1164.8 / 47.1
Test statistic = 24.73
The degree of freedom, df = n - 1 ; 10 = 9
Critical value (0.05, 9) = 16.92 (Chisquare distribution table)
Reject H0 ; If Test statistic > Critical value
Since ; 24.73 > 16.92 ; Reject H0 and conclude that variance is greater.
Answer: 2(2x+4y)
Step-by-step explanation:
4(x+2y) would be simplified to 4x+8y, so you just have to make an expression that would get you that answer.
