The <span>perimeter of a face of the new cube is 8 times larger than the previous cube.
</span>Let us say, the side of cube before increase is "a"
Then perimeter of the cube = 12a ,
because the cube has 12 sides.
And perimeter of a face of cube = 4a
Now, the side length is increased by factor of 3 i.e. new side is 3a
Thus, perimeter of new face of the cube = 4*3a = 12a
Therefore, the new perimeter is larger by = 12a - 4a = 8a
Answer: 2x³(x² + 5x - 11)
<u>Step-by-step explanation:</u>
2x⁵ + 10x⁴ - 22x³
Factor out the GCF (2x³)
2x³(x² + 5x - 11)
Since there are no values whose product is -11 and sum is +5, this cannot be factored further.
Answer:
We have a right tailed test then the p value would be:
Step-by-step explanation:
Information provided
n=497 represent the random sample of homes selected
X=340 represent the number of homes with one or more lawn
estimated proportion of homes with one or more lawn
is the value that we want to test
z would represent the statistic
represent the p value (variable of interest)
System of hypothesis
We want to check if proportion of homeowners owning lawn mowers in charlotte is higher than 65%m so then the correct hypothesis are .:
Null hypothesis:
Alternative hypothesis:
The statistic is given by:
(1)
Replacing the info given we got:
We have a right tailed test then the p value would be:
