DE=BD=BE=3.5Use polar coordinates to find the volume of the given solid. Inside both the cylinder x2 y2 = 1 and the ellipsoid 4x2 4y2 z2 = 64
The Volume of the given solid using polar coordinate is:[tex]\frac{-1}{6} \int\limits^{2\pi}_ {0} [(60) ^{3/2} \; -(64) ^{3/2} ] d\theta[/tex]
V= [tex]\frac{-1}{6} \int\limits^{2\pi}_ {0} [(60) ^{3/2} \; -(64) ^{3/2} ] d\theta[/tex]
What is Volume of Solid in polar coordinates?
To find the volume in polar coordinates bounded above by a surface z=f(r,θ) over a region on the xy-plane, use a double integral in polar coordinates.
Consider the cylinder,[tex]x^{2}+y^{2} =1[/tex] and the ellipsoid, [tex]4x^{2}+ 4y^{2} + z^{2} =64[/tex]
In polar coordinates, we know that
[tex]x^{2}+y^{2} =r^{2}[/tex]
So, the ellipsoid gives
[tex]4{(x^{2}+ y^{2)} + z^{2} =64[/tex]
4([tex]r^{2}[/tex]) + [tex]z^{2}[/tex] = 64
[tex]z^{2}[/tex] = 64- 4([tex]r^{2}[/tex])
z=± [tex]\sqrt{64-4r^{2} }[/tex]
So, the volume of the solid is given by:
V= [tex]\int\limits^{2\pi}_ 0 \int\limits^1_0{} \, [\sqrt{64-4r^{2} }- (-\sqrt{64-4r^{2} })] r dr d\theta[/tex]
= [tex]2\int\limits^{2\pi}_ 0 \int\limits^1_0 \, r\sqrt{64-4r^{2} } r dr d\theta[/tex]
To solve the integral take, [tex]64-4r^{2}[/tex] = t
dt= -8rdr
rdr = [tex]\frac{-1}{8} dt[/tex]
So, the integral [tex]\int\ r\sqrt{64-4r^{2} } rdr[/tex] become
=[tex]\int\ \sqrt{t } \frac{-1}{8} dt[/tex]
= [tex]\frac{-1}{12} t^{3/2}[/tex]
=[tex]\frac{-1}{12} (64-4r^{2}) ^{3/2}[/tex]
so on applying the limit, the volume becomes
V= [tex]2\int\limits^{2\pi}_ {0} \int\limits^1_0{} \, \frac{-1}{12} (64-4r^{2}) ^{3/2} d\theta[/tex]
=[tex]\frac{-1}{6} \int\limits^{2\pi}_ {0} [(64-4(1)^{2}) ^{3/2} \; -(64-4(2)^{0}) ^{3/2} ] d\theta[/tex]
V = [tex]\frac{-1}{6} \int\limits^{2\pi}_ {0} [(60) ^{3/2} \; -(64) ^{3/2} ] d\theta[/tex]
Since, further the integral isn't having any term of [tex]\theta[/tex].
we will end here.

There are 36 pieces of building blocks in a bag: 9 each of blue, green, red, and yellow. Four pieces are chosen at random. Identify the probability that all four of the pieces are red.
Answer:
2/935
Step-by-step explanation:
I have attached an image of the equation to use. Assuming that this is without replacement, we'll be taking out one piece out of the bag every time that one is chosen.
Therefore, for probability, the fraction is part/whole. We first have 9 red to 36 pieces in total, but if we take one out, we'll get 8 red left in the bag, and 35 pieces in total. This continues until we fulfill the prophecy (I don't know. qualifications?) that 4 of the pieces are red.
You can try this for yourself, but once simplified, it should be 3024/1413720, which simplifies to 2/935.

Taylor has a punch bowl shaped like a cylinder, with a diameter of 22 inches and a height of 20 inches, she pours 8.25 gallons of punch into the bowl.
(note 1 gallon = 231 cubic inches)
How far from the top of the punch bowl is the top of the punch?
Answer:
1 gal =231 cu/in
r^2pi*ht=area
36pi*7= 791.68cu/in
231*3.25=750cu/in
41.68/(r^2pi)
=41.65/113.1=.368"
Step-by-step explanation:
Note that 1 gallon = 231 cubic inches.
Volume of liquid = 231 cubic inches = PI*R^2*H (equation for volume of a cylinder)
We have a radius (half diameter), so we can figure out the height of the liquid.
To figure how far below the top the liquid is, we subtract the height of the liquid from the height of the punch bowl (7 inches).

A Crime scene investigator arrived at an auto accident to collect information. A car had hit a pedestrian sending a box he was carrying into the air. Luckily, the pedestrian was unharmed. In order to determine the speed the car was travelling at impact, the investigator needs to find out how high the box went into the air. Here aare the notes that he took from the scene. A 5 foot tall witness said that he saw the box fly up just above a tree next to where the accident happened. He was standing 25 feet from a tree. The angle of elevation as the witness looked up at the tree was 45. Determine the height of the tree, which will tell you the height the box flew into the air.
Answer:
no the height of the tree doesnt determine the heiht of the box, thatd be a pretty large box if so

3. If A and B are complements, then which of the following is true about the probability of B based on the probability of A?
(1) P(B)=P(A)+1
(3) P(B) =1/P(A)
(2) P(B)=1-P(A)
(4) P(B)=P(A)-1
Reason:
Complementary events have their probabilities add to 1.
P(A)+P(B) = 1
P(B) = 1 - P(A)
For example,
P(A) = the chance it rains = 30% = 0.30
P(B) = the chance it doesn't rain
P(B) = 1 - P(A) = 1 - 0.30 = 0.70 = 70%
The equation that relates the probability of A and B is P(B) = 1 - P(A).
What is Probability?A random event's occurrence is the subject of this area of mathematics. The range of the value is 0 to 1.
As per the given data:
We are given two events, event A and event B.
We are also given the relationship between the two events.
It's given that A and B are complements of each other.
Let's assume that the probability of the event B is P(B).
The sample space for this situation when only 2 events are there will be
(A, B)
We are given that A and B are complements of each other.
This means that the complement of A is equal to the probability of event B.
P(A') = 1 - P(A)
P(B) = P(A')
∴ P(B) = 1 - P(A)
The equation that relates the probability of A and B is P(B) = 1 - P(A).
Hence, The equation that relates the probability of A and B is P(B) = 1 - P(A).

Answer:
Discount = $4.50
Discounted Price = $40.50
Step-by-step explanation:
First you need to find what 10% of $45 is. To do that you need to divide $45 by 10 or just move the decimal point one space to the left. The answer would be $4.50. Then, you need to subtract $4.50 from $45 as we are calculating the discounted price. The answer would be $40.50.
Equation:
$45 ÷ 10 = $4.50 (discount)
$45 - $4.50 = $40.50 (discounted price)

(c) Who did relatively better on their test, Boris or Callie? Use the meaning of z-scores to explain
The Z-score for Boris is 1.627, and the Z-score value for the Callie is 1.267, Boris scored higher relatively.
What is Z-test?The Z test is a parametric procedure that is used on data that is dispersed in a normal fashion. For testing hypotheses, the z test can be used on one sample, two samples, or proportions. When the population variance is known, it analyzes if the means of two big groups are dissimilar.
We know the formula for the Z-test:
[tex]\rm Z = \dfrac{X-\mu}{\sigma}[/tex]
(a) For Boris:
[tex]\rm Z = \dfrac{67-60}{4.3}[/tex]
Z = 1.627
(b) For Callie:
[tex]\rm Z = \dfrac{119-110}{7.1}[/tex]
Z = 1.267
(c) Since the measures of two different data have been set to one measure and the value of the Z-score for Boris is higher relative to the Z-score value of Callie so Boris scored higher relatively.
Thus, the Z-score for Boris is 1.627, and the Z-score value for the Callie is 1.267, Boris scored higher relatively.

If a fair die is rolled 7 times, what is the probability, rounded to the nearest thousandth, of getting at least 4 threes?
Answer:
0.904
EX ; Each time the die is rolled, there are only two possible outcomes, either the result is a 2, or it is not. The result on a roll is independent of any other roll, which means that the binomial distribution is used to solve this question.
Binomial probability distribution
- The parameters are:
x is the number of successes.
n is the number of trials.
p is the probability of a success on a single trial.
In this problem:
- The die is rolled 7 times, hence .
One out of the 6 sides is a 2, hence
- Then:
0.905 = 90.5% probability of getting at most 2 twos.
