Xy^9/xy^3 that is the answer
Answer:
width: 7 cm
length: 56 cm
Step-by-step explanation:
Let:
x=width
8x=length
P=2l+2w
126=2x + 2(8x)
126=2x+16x
18x=126
x=7
width: 7 cm
length: 56 cm
hope this helps!!
Answer:
D. variables
Step-by-step explanation:
The original bill was valued at 106.67 $
if 25% was paid, and 80 dollars are left, this means that 80 dollars is 75% of the bill. 25% is a quater, and 75% is three quarters.
here, we can divide 80 into three parts ->
80 ÷ 3 ≈ 26.67
that means a quater of the bill is 26.67 $
if 80$ were left to be paid, just add the 26.67$ from the first quater ->
80 + 26.67 = 106.67 $
Answer:One can do a two-proportion test and find that the z-value for different is 1.28 (or -1.28, depending how one sets up the test).
The p-value for that is 0.20, so by most tests this is not statistically significant.
Said another way, if there had been no change in the interval, the probability of having a repeat sample at least this different would be 0.20.
The parameter one is attempting to determine is the true proportion of adults in the US who say they like pizza.
For those who think it is 50%, it is essentially 100% likely that it is not 50% but much higher, around 75-77%.
