First one is Equal
Second is Not Equal
5.30 x 285 =1225.5
this is the answer hope it helps
The sample size should be 73.
We use the formula
To find the z-score:
Convert 95% to a decimal: 0.95
Subtract from 1: 1-0.95 = 0.05
Divide by 2: 0.05/2 = 0.025
Subtract from 1: 1-0.025 = 0.975
Using a z-table (http://www.z-table.com) we see that this value goes with a z-score of 1.96. Using this, our value for σ and our margin of error, we have:
Answer:
Step-by-step explanation:
9(x + 1) = 25 + x
9x + 9 = 25 + x
Bringing like terms on one side
9x - x = 25 - 9
8x = 16
x = 16/8 = 2
The values of x and y is x = 2 1/4, y = 6.
We can write the corresponding dimensions:
Larger: smaller
Heigh: 8 : y
Width: 12 : 9
Depth: 3 : x
Since the figures are similar, corresponding values are proportional. This means
y/8 = 9/12
y = 8(9/12)
y = 6
x/3 = 9/12
x = 3(9/12) = 9/4
x = 2 1/4
