Answer:
The length side of the pre-image is 16 units
Step-by-step explanation:
we know that
The length side of the image is equal to the length side of the pre-image multiplied by the scale factor
or
The length side of the pre-image is equal to the length side of the image divided by the scale factor
in this problem we have that
The scale factor is 1/2
The length side of the image is 8 units
therefore
8/(1/2)=16 units
The length side of the pre-image is 16 units
Answer:
78
Step-by-step explanation:
The total you are buying is 112 pounds. The can you have picked up is 34 pounds; this leaves
112-34 = 78 pounds remaining.
In statistics, the amount of degrees of freedom is
the quantity of values in the final computation of a statistic that are free to
differ. In this case, you can get the answer by adding the number of bags
and subtracting 1.
So in computation, this would look like: 3 + 2 + 1 + 2 - 1 =
7
Therefore, 7 is the degrees of freedom.
The first thing you have to do is to divide the personal income by the percen it takes up
<span>2,176.10/47=46.3
that means that 46.3 is 1% of the whole, so if we multiply it by 100 you will get the whole
</span>
46.3*100=4630
so the answer is
4,<span>630</span>
Answer:
The correct option is;
d. 24.2 to 25.6
Step-by-step explanation:
Here we have a sample with unknown population standard deviation, we therefore apply the student t distribution at 64 - 1 degrees of freedom
Therefore, we have

Where:
= Mean = 25
σ = Standard deviation = 2
n = Sample size = 64
t = T value at 98% = 
Which gives

That is the value is from
24.40325 to 25.59675 which gives,by rounding to one decimal place, is
24.4 to 25.6.
