vova2212 [387]

Answer:

<u>Based on the results the boutique could be located there.</u>

<u>Step-by-step explanation:</u>

Note: The average income (the mean) is calculated by summing the total incomes then divided by the total sample–9.

The mean ù (average income) = $28,000 + $24,000 + $26,000 + $25,000 + $23,000 + $27,000 + $26,000 + $22,000 + $24,000= $225,000/9= $25,000 (which is ≥ $25,000.

Based on the results of the p-value, using the 5% significant level <em>we fail to reject the null hypothesis</em> (ú≥25,000).

Kesia knows that 1/4 = 0.25. Explain how she could use this fact to determine the decimal equivalent of 5/8.
guapka [62]
Well if you split 1/4 in half then that will give 1/8. You must also split 0.25 in half which gives 0.125
\frac{1}{8} = 0.125
Now you can multiply that by 5 which gives 5/8. But also the fraction
\frac{1}{8} \times 5 = 0.125 \times 5 \\&#10;\frac{5}{8} = 0.625
Now we know that 5/8 = 0.625

A = 310 rounded to the nearest 10
GREYUIT [131]

Answer:

a = (rounded) 310

b = (rounded) 66.1

These two were already rounded to their designated rounding value.

a/b = (rounded) 4.69

You round up since the 3rd DP is greater than or equal to 5.

The length of a rectangle is 2 more than twice the width. The perimeter is 76 feet. Find the length and width of the rectangle.
vlabodo [156]
So we can set x= width
2x+2 = length
so 2(x)+2(2x+2)= 76
so that will give us 2x+4x+4=76
6x=72
x=12
so 12 is width and 26 is length
