Answer:
7/6
Step-by-step explanation:
Subtract 2 from both sides and subtract 7 from both sides and get -14/-12x and make the fraction smaller and get 7/6.
Length of the actual bathroom = 20 x 2 inches = 40 inches = 10/3 ft
Width of the actual bathroom = 20 x 3.5 inches = 70 inches = 35/6 ft
Area of the actual bathroom = length x width = 10/3 x 35/6 = 19 square ft.
Answer:
Step-by-step explanation:
a)
Number of sample, n = 100
p = 0.78
q = 1 - p = 1 - 0.78
q = 0.22
For a confidence level of 90%, the corresponding z value is 1.645.
The formula for determining the error bound for the proportion is
z × √pq/n
= 1.645 ×√(0.78 × 0.22)/100
= 1.645 × 0.0414 = 0.068
The upper boundary of the population proportion is
0.78 + 0.068 = 0.85
The lower boundary of the population proportion is
0.78 - 0.068 = 0.71
b) For a confidence level of 95%, the corresponding z value is 1.96.
Therefore,
= 1.96 ×√(0.78 × 0.22)/100
= 1.96 × 0.0414 = 0.081
The upper boundary of the population proportion is
0.78 + 0.081 = 0.86
The lower boundary of the population proportion is
0.78 - 0.081 = 0.7
Transforming
to
gives the effect of squashing the graph horizontally (by halving the x-coordinate)
Then from
to
is reflecting on the y-axis
Then from
to
is to translate by 4 units to the right
Finally from
to
is translating the graph up by 5 units
Answer:
I think the answer is 3/8 bight i might be wrong.
Step-by-step explanation:
3/4*1/2=3/8
All I did was multiply the two fractions.
