<span>Brittany's mom should get two packages of hot dogs and three packages of buns to get the equal number of hot dogs to buns. In order to determine this, I multiplied 24 by 2 and got 48. I multiplied 16 by 3 and also got 48. The least asmount of packages she should buy are two packages of hot dogs and three packages of buns so she has an equal amount of both.</span>
It is expected the height of the melted wax in this shape is 9.57 inches, this height would make the volume remain constant.
<h3>What is the volume of the spherical ball?</h3>
The volume of a sphere can be calculated using the formula V = 4/3 πr³. Let's use this formula to calculate the volume of the spherical ball of wax:
- V = 4/3 π8³
- V = 4/3 π 512
- V= 4/3 x 3.1416 x 512
- V =2144.66 cubic inches
<h3>What is the height of the new shape?</h3>
Considering the volume should be the same (2144.66 cubic inches) and the volume of this shape can be calculated by multiplying the sides, this would be the equation:
- 2144.66 = 14 x 16 x y ( unknown value)
- y= 2144.66 / 14 x 16
- y = 9.57
This means the height would be 9.57 inches.

Answer:
BD = 8.5 units
Step-by-step explanation:
From the figure attached,
ΔABC and ΔADB are the right triangles.
By applying mean proportional theorem,

BD² = AD × CD
BD² = 6 × 12
BD = √72
BD = 6√2
= 8.485
BD ≈ 8.5 units
Therefore, measure of segment BD will be 8.5 units.
Answer:
The 95% confidence interval for the average heights of the population is between 1.7108m and 1.7892m.
Step-by-step explanation:
We have that to find our
level, that is the subtraction of 1 by the confidence interval divided by 2. So:

Now, we have to find z in the Ztable as such z has a pvalue of
.
So it is z with a pvalue of
, so 
Now, find M as such

In which
is the standard deviation of the population and n is the size of the sample.
The standard deviation is the square root of the variance. So

Then

The lower end of the interval is the mean subtracted by M. So it is 1.75 - 0.0392 = 1.7108m
The upper end of the interval is the mean added to M. So it is 1.75 + 0.0392 = 1.7892m
The 95% confidence interval for the average heights of the population is between 1.7108m and 1.7892m.
