Answer:
Step-by-step explanation:
Problem One
The scoop is a semisphere I would assume.
The volume of a semisphere = 2/3 * pi * r^2
r = d/2
r = 2/2 = 1
Volume = 2/3 * 3.14 * 1^3
Volume = 2.093
Volume of cone
V = 1/3 * pi * r^2 * h
r = 1
h = 6
V = 1/3 * 3.14 * 1^2 * 6
V = 6.28
Total volume = 8.373
Note: this could be incorrect. It's not clear whether the 2 is a diameter or a radius.
Problem 2
Use the Circumference to find R
C = 2*pi*r
C = 150
r = ?
150 = 2 * 3.14 * r
r = 23.89
Find the area
Area = pi r^2
r = 23.89
Area = 3.14 * 23.89^2
Area = 1791.4 square feet.
Problem 3
The center is 5,-6
The formula is
(x - 5)^2 + (y+6) = 12^2
Experiment 1: Select ONE card from a deck of cards Create two events A and B. For example: Let A = observing a card with an odd number on it B = observing a king Mix and match two events anyway you like.
Answer:
The answer is "64".
Step-by-step explanation:
Let A= look at the number of a card on it {3,5,7,9}
[tex]\to 4 \times 4 = 16 \ odd \ numbers[/tex]
Let B= look at the king of the card = [tex]4 \ Cards[/tex]
Choose one card A = 16 ways
Choose one card B= 4 ways
selecting one card, either A and B:
[tex]=A \times B \\\\= 16 \times 4 \\\\= 64[/tex]

Big brain calculator work
28 + 35 + 42 + 49 + 56 + 63 + 70 = 343
Answer:
343
Step-by-step explanation:
28+35+42+49+56+63+70 We are asked to find the sum, so we add all the numbers in the series.
28+35+42+49+56+63+70 = 343
Which expression is equivalent to 8x- 2y - + x + x
A.4x
B.8x
C.6x - 2y
D.10x - 2y
Answer:
C
Step-by-step explanation:
Subtract like-terms. -2y is the only variable that has a y and is therefore unaffected. 8x - x - x = 6x.

In a set of three lines, a pair of parallel lines is intersected by a transversal. The intersection forms eight special angles. Two of the special angles, A and B, are corresponding angles.
For the set of parallel lines intersected by a transversal, A=4x and B=-5(x-18).
Part A: Write an equation to represent the corresponding relationship betweenA andB.
Part B: Use the equation to find the measures of A and B.
Answer:
Part A: 4x = -5(x-18)
Part B: A and B both = 40 degrees
Step-by-step explanation:
Ok, corresponding angles are in the same position on the two parallel lines cut by the transversal. And they are equal in measure. So, upper right = upper right.
So A = B
4x = -5(x -18)
4x = -5x + 90
9x = 90
x = 10
Angle A = 4x = 40 degrees, which means angle B is also 40, but let's show the work:
Angle B = -5(x - 18) = -50 + 90 = 40

In the 1990s, it was generally believed that genetic abnormalities affected about 5% of a large nation's children. Some people believe that the increase in the number of chemicals in the environment has led to an increase in the incidence of abnormalities, which could have important implications for health insurance companies. A recent study examined 384 randomly selected children and found that 25 of them showed signs of a genetic abnormality.
Required:
What is the p value?
Answer:
The p-value of the test is 0.0869.
Step-by-step explanation:
In the 1990s, it was generally believed that genetic abnormalities affected about 5% of a large nation's children.
This means that the null hypothesis is:
[tex]H_{0}: p = 0.05[/tex]
Some people believe that the increase in the number of chemicals in the environment has led to an increase in the incidence of abnormalities.
This means that the alternate hypothesis is:
[tex]H_{a}: p > 0.05[/tex]
The test statistic is:
[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]
In which X is the sample mean, [tex]\mu[/tex] is the value tested at the null hypothesis, [tex]\sigma[/tex] is the standard deviation and n is the size of the sample.
5% tested at the null hypothesis:
This means that:
[tex]\mu = 0.05, \sigma = \sqrt{0.05*0.95}[/tex]
A recent study examined 384 randomly selected children and found that 25 of them showed signs of a genetic abnormality.
This means that [tex]n = 384, X = \frac{25}{384} = 0.0651[/tex]
Test statistic:
[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]
[tex]z = \frac{0.0651 - 0.05}{\frac{\sqrt{0.05*0.95}}{\sqrt{384}}}[/tex]
[tex]z = 1.36[/tex]
p-value:
Testing if the mean is bigger than a value, so the pvalue is the probability of finding a value in the z table higher than 1.36, which is 1 subtracted by the pvalue of z = 1.36.
z = 1.36 has a pvalue of 0.9131
1 - 0.9131 = 0.0869
The p-value of the test is 0.0869.
Answer ASAP for BRAINLIEST (NO LINKS OR I REPORT)
Answer:
radius = 3 feet
Step-by-step explanation:
V = 1/3πr²h
15π = 1/3πr²·5
you can divide each side by 5π to get:
3 = r²/3
r² = 9
r = [tex]\sqrt{9}[/tex] which is 3
Answer:
3
Step-by-step explanation:
((r^2)h[tex]\pi[/tex] )/3=volume of a cone
[tex]15\pi =((r^2)h\pi )/3[/tex]
they say that the height is 5 so insert 5 for h
[tex]15\pi =\frac{r^2(5)\pi } {3}[/tex]
solve for r
multiply both sides by 3
[tex]45\pi =r^25\pi[/tex]
divide both sides by 5
[tex]9\pi =r^2\pi[/tex]
[tex]r=3[/tex]

Answer:
12.8
Step-by-step explanation:
imagine a right triangle in the middle,
base: 16 ÷ 2 = 8 cm, height: 10 cm, side: s
10² + 8² = s²
=> s = √(10² + 8²)
=> s = √(100 + 64)
=> s = √164
=> s ≈ 12.8

Please please help me please please help please
Please help this is important
Answer:
x = 18.8
Step-by-step explanation:
(6x + 19) is in linear pair vertically so,
it's value will be 180 - 6x + 19. ......( angles in linear pair are supplementary)
now, 180 - 6x + 19 is corresponding with (4x + 11)
therefore, 4x + 11 = 180 - 6x + 19
4x + 6x = 180 + 19 - 11
10 x. = 180 + 8
10 x. = 188
x = 188/10
x. = 18.8
Cross - check:-
4x + 11 = 180 - 6x + 19
4 * 18.8 + 11 = 180 - ( 6 * 18.8 +19)
86.2. = 86.2
therefore, x = 18.8 is the correct answer

Answer:
The 4th cone
Step-by-step explanation:
Hello, the answer to your question is the 4th cone; the cone with its bottom half facing skyward. If you are familiar with plane symmetry, this question is fairly simple. Since the topmost cone has its bottom half facing downward, it would only be logical to choose the cone that forms mirror halves (superimpose) when paired.
