1. devin is making a candle by pouring melted wax into a mold in the shape of a square pyramid. each side of the base of the pyramid is 6 cm and the height of the pyramid is 9 cm. to get the wax for the candle, devin melts cubes of wax that are each 4 cm by 4 cm by 4 cm. how many of the wax cubes will devin need in order to make the candle? show your work.
Answer:
1.69
approximately 2 wax cubes
Step-by-step explanation:
number of wax cubes needed = volume of square pyramid / volume of cube
Volume of a pyramid = 1/3 x ( base area x height)
base area = length²
6² = 36
volume = 1/3 x (36 x 9) = 108
volume of a cube = length³
4³ = 64cm³
108/64 = 1.69

The height of a cone is twice the radius of its base.
What expression represents the volume of the cone, in
cubic units?
2/3лх^3
4/3лх^3
2лх^3
4лх^3
Answer: 2/3πx³
Step-by-step explanation:
Let the radius of the cone be represented by x.
Since the height of the cone is twice the radius of its base, the height will be: = 2x
Volume of a cone = 1/3πr²h
where,
r = x
h = 2x
Volume of a cone = 1/3πr²h
= 1/3 × π × x² × 2x
= 1/3 × π × x² × 2x
= 1/3 × π × 2x³
= 2/3πx³
Therefore, the correct answer is 2/3πx³.
Fill in the blanks using the following choices: reject, fail to reject, sufficient, enough, not sufficient, not enough If the p value is 0.32 to test if there is a difference exists between the proportion of students who have ear infections at one school and the other, your decision is to the null and the conclusion: There is evidence to support the alternative that the proportion of students who have ear infections at one school and the other are different.
Answer:
FAIL TO REJECT
NOT ENOUGH
Step-by-step explanation:
Given a Pvalue of 0.32
Decision region :
When Pvalue < α ; Reject the Null and conclude that there is significant or enough evidence to accept the alternative hypothesis.
Otherwise, fail to reject reject the null and conclude that, there is not enough evidence to accept the alternative hypothesis
Therefore, for the scenario above, where Pvalue = 0.32
Possible α values are ; 0.1, 0.05, 0.01
For all α - values listed, the Pvalue is greater than α
Pvalue > α ; Hence, FAIL TO REJECT the Null.
Conclusion :
There is NOT ENOUGH evidence to support the alternative that the proportion of students who have ear infection at one school and the other is different.

Answer:
Step-by-step explanation:
3 time 2 with the power of t
You see the given values, 1 and 4?
All you need to do is replace those values with 1 and 4.
3 x 2 with the power of 1.
2 times the power of one is just 2 because you aren't multiplying it with another 2.
So, 3 times 2 is 6.
3 x 2 with the power of 4
2 x 2 x 2 x 2 = 16
It's not 2 times 4; it's 2 times the power of 4-- which means we multiply the number by itself depending on the given value we're given.
I hope this helps!

This probability distribution shows the typical grade distribution for a Geometry course with 35 students. Frequency 5 10 15 3 2 Find the probability that a student earns a grade of B
Answer:
0.29
Step-by-step explanation:
Total number of students = 35
Number of students who got B = 10
Probability that a student earns grade B :
Probability = required outcome / Total possible outcomes
P(grade B) = 10 / 35 = 0.2875
= 0.29

Ramon invested a total $9,700 into two accounts, account 1 earns 6% simple interest and account 2 earns 4% simple interest. After one year, the total interest earned from both accounts was $466. Let X be the amount you invested in account 1 and y be the amount invested in account 2
Answer:
In the account that paid 3% Ramon put $800
In the account that paid 6% Ramon put $1,600
Step-by-step explanation:
Answer:
x+y= 9700 & 0.06x + 0.04y=466
Step-by-step explanation:
let X & Y be each account. Together, they are $9,700.
So, x+y=9700
thus, account 1 (x) earns 6 %. which converted to decimal is 0.06
account 2 (y) earns 4 % which converted is 0.04
It also said that both accounts were $466, after 1 year.
0.06x+0.04y=466

Which is 3 logx + 4 log(x-2) written as a single logarithm?
logx (x - 2)
logx(x-2)
b. 12 logx(x - 2)
d. 12 logx(x-2)
Answer:
The answer is [tex]12\log{(x(x-2))}[/tex]
Step-by-step explanation:
Exponential property of logarithm:
We have that:
[tex]a \log{x} = \log{x^{a}}[/tex]
Sum of logarithms:
We have that:
[tex]\log{a} + \log{b} = \log{ab}[/tex]
Applying the exponential property:
[tex]3\log{x} = \log{x^3}[/tex]
[tex]4\log{(x-2)} = \log{(x-2)^4}[/tex]
So
[tex]3\log{x} + 4\log{x-2} = \log{x^3} + \log{(x-2)^4}[/tex]
Additive property
[tex]\log{x^3} + \log{(x-2)^4} = \log{x^3(x-2)^4} = \log{(x(x-2))^12}[/tex]
Exponential property:
[tex]\log{(x(x-2))^12} = 12\log{(x(x-2))}[/tex]
The answer is [tex]12\log{(x(x-2))}[/tex]
Mr. A is white, non-hispanic, 20 years old, and a high school dropout. Using the probit regression, assuming that Mr. A is not subject to a workplace smoking ban, calculate the probability that Mr. A smokes. Carry out the calculation again, assuming that he is subject to a workplace smoking ban. What is the effect of the smoking ban on the probability of smoking
Answer: Hi Your question lacks some information but i will give you a general solution with similar data found online
answer
a) 15.15%
b) The effect on The probability of smoking is that the p( smoking ) will reduce from 15.15% to 11.70%
Step-by-step explanation:
Using The probit regression
from the attached question ;
for smoking
1 = smokes , 0 = do not smoke
For Independent variable
1 = ban at workplace , 0 = not ban at workplace.
sex : male = 0 , female = 1
a) Assuming Mr. A is not subject to a workplace smoking ban
P ( Mr. A smokes ) = 15.15%
b) Assuming Mr. A is subject to a workplace smoking ban
determine effect on P ( Mr. A smokes )
The effect on The probability of smoking is that the p( smoking ) will reduce from 15.15% to 11.70%

A class of 118 students went on a field trip. They took 10 vehicles, some vans (x) and some buses (y). Find the number of vans and the number of buses they took if each van holds 6 students and each bus hold 35 students. Express your answer as a solution set {x, y} or (x, y).
Answer:
Solve for x+y=10
6x+35y=118
Step-by-step explanation:
I would solve it for you but my calculator isn't working rn. You could also use a picture calculator and it will give you a more in depth explanation. Hope this helps!
Answer:
{ 8, 2}
Step-by-step explanation:
Basic algebra, the object which is not in a set quantity, which we have to find, is the "some vans" and the "some buses"
So let the number of van be x
Let the number of buses be y
So, since there are 10 vehicles,
x+y=10
Makes sense right
Now, it says that every car can carry 6 students, and every van can carry 35 students, so in another way, we could represent this by saying
6 x Number of van + 35 x Number of buses
thus,
6x + 35y
And since 118 students went on the field trip, this means that
6x +35y = 118
So now we have two equations,
x + y = 10
6x + 35y = 118
We can solve this with substitution
x + y = 10
x = 10 - y
Thus, x = 10-y
Put this in this
6(10-y)+ 35y= 118
60-6y+35y=118
60+29y=118
29y=118-60
29y= 58
y = 58/29
y = 2
Thus, the number of buses, y, is 2
Now since there are 10 vehicles, and 2 are buses, then the other are 8 van

degrees
The measure of arc JPK =
degrees
The segment lengths and the arc measures are NK = 12, JK = 24, arc MK = 53.1 degrees and arc JPK = 253.8 degrees
Calculating the segment lengths and the arc measuresFrom the question, we have the following parameters that can be used in our computation:
The circle
Using the pythagoras theorem, we have
NK^2 = 15^2 - 9^2
NK^2 = 144
So, we have
NK = 12
Next, we have
JK = 2 * NK
So, we have
JK = 2 * 12
Evaluate the product
JK = 24
For the arc measures, we have
arc MK = arc cos(9/15)
So, we have
arc MK = 53.1 degrees
Next, we have
arc JPK = 360 - 2 * 53.1 degrees
Evaluate
arc JPK = 253.8 degrees
Hence, the measure of the arc JPK is 253.8 degrees

Answer:
8.2 m
Step-by-step explanation:
To solve the problem, we use pythagorean theorem, which is a^2 + b^2 = c^2. We are given both the legs, so we can substitute them in:
8^2 + 2^2 = c^2
And simplify to get:
c^2 = 64 + 4
c^2 = 68
Now, we find the square root of both sides to isolate c:
c = √68
√68 is approximately 8.24621125124
This rounded to the nearest tenth is 8.2 m
