Answer:
In solving an equation where one fraction is equal to another fraction we can use the method of cross-multiplication
⇒x+6x=107
Now multiply the red terms together, the blue terms together and equate them.
⇒10x=7(x+6)
distribute the bracket.

Step-by-step explanation:
Answer:
7/√2 cm
Step-by-step explanation:
Area of circle = 77 cm^2
=> π(r)^2 = 77
=> (22/7) x (r)^2 = 77
=> (r)^2 = (77 x 7) / 22
=> (r)^2 = 49/2
=> (r) = 7/√2 cm
Answer:
B) No, because the p-value is greater than any reasonable significance level
Step-by-step explanation:
H-null: p = 0.41
H-alt: p =/= 0.41
1 proportion Z test
On a calculator: stat + tests + 5
p: .41
x: 245
n: 600
prop: =/= p
This gives a p-value = .934
(standard significance level is .05, so this p-value is much larger)
fail to reject H-null
Answer:
$56.67
Step-by-step explanation:
$30+$21.50+$50=101.50
$101.50-$18=$83.50
$83.50-$26.83=$56.67
