Erik states that the two cones below have the same volume because of Cavalieri’s principle. 2 cones are shown. The first cone has a radius of r, a slant length of c, and a height of b. The second cone has a radius of r, a height of a, and a slant length of b. Is Erik’s statement correct? Why or why not? Yes, the solids are both cones and appear to have the same volumes. Yes, the area of the bases and the heights of the cones are the same, so the volumes are equal. No, the heights of the cones are not the same, so Cavalieri’s principle does not apply.
Answer:
D. No, the heights of the cones are not the same, so Cavalieri’s principle does not apply.

Answer:
m<3 = 97
m<10 = 97
m<9 = 83
m<5 = 97
m<7 = 83
m<16 = 97
Step-by-step explanation:
m<3 = m<2 because of vertical angles
m<10 = m<2 because of corresponding angles
m<9 + 97 = 180
m<9 = 83
m<5 + 83 = 180
m<5 = 97
m<7 = m<6 because of vertical angles
m<16 = m<5 because of alternate exterior angles.
In general, describe how the outcome of the hypothesis test changes as the level of significance decreases.
Answer:
The region of acceptance gets bigger and the null hypothesis is mostly accepted as it lies in the acceptance region.
Step-by-step explanation:
As the level of significance is decreased the area for the favorable outcomes is increased. The value of ∝= 0.1 has a narrower area of favorable outcomes then the values of ∝= 0.05 or 0.01 because the value 0.1 ( 1%) is closer to the middle value or at the extreme values of the distribution as the case may be for 2 tailed or 1 tailed test.
Significance level Two tailed Test One tailed test
0.1 ± 1.645 ±1.28
0.05 ±1.96 ± 1.645
0.01 ± 2.58 ± 2.33
So if the middle point is taken as zero we see that the spread of the area of the favorable values increases as the value of ∝ significance level decreases.
The region of acceptance gets bigger and the null hypothesis is mostly accepted as it lies in the acceptance region.

What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
Let the temperatures on different days be represented by the table
Now , total temperature is S = -6 + 3 + 4 - 2 - 1
On simplifying the equation , we get
S = -2°C
Hence , the temperature is S = -2°C

A salesperson receives a base salary of $35,000 and a commission of 10% of the total sales for the year. If a salesperson sells $250,000 worth of merchandise, what is her total income for the year, including her base salary?
Answer:
$60,000
Step-by-step explanation:
Given data
Base salary=$35000
commssion= 10%
Sales= $250,000
Let us find the commission
=10/100* 250,000
=0.1*250,000
=25000
Hence the total income is
=25000+35000
=$60,000

I just need to solve this: 5x^3=60x
determine the intercepts of the line
Answer:
(0, -5/2), (-2, 0)
Step-by-step explanation:
To find the y-intercept, set x = to 0 and find y: -4y = 10. Thus, y = -5/2. The y-intercept is (0, -5/2).
To find the x-intercept, set y = to 0 and fid x: -5x = 10. Therefore the x-intercept is -2: (-2, 0)

There are 12 brown hair teachers and 20 blond hair teachers. For every blank blond teachers there are blank brown teachers
Answer:
For every 5 blonde teachers there are 3 brown teachers.
Step-by-step explanation:
Here we have to find the ratio of blonde teachers to brown teachers
Blonde : Brown
20: 12
10:6
5:3
For every 5 blonde teachers there are 3 brown teachers.
This can be further evaluated
Blonde : Brown
5:3
dividing both sides by 5
1: 3/5
For every 1 blonde teachers there are 3/5 brown teachers. It means that the brown teachers are 2/5 less than the blonde teachers.
1-2/5= 3/5
20* 3/5= 12
Martin says that f(x)=2(4)^x starts at 4 and has a constant ratio of 2. What error did Martin make? Explain.
Answer:
A general exponential equation is written as:
f(x) = A*(r)^x
Where:
A is the initial value, this is the value that the function takes when x = 0.
r is the rate of growth
x is the variable.
In this case, the function is:
f(x) = 2*(4)^x
The initial value is:
f(0) = 2*(4)^0 = 2*1 = 2
The initial value is 2.
And the rate of growth is 4.
So Martin seems to mixed these two values (he said initial value = 4, and rate = 2, which is the opposite of what we found)
One angle of a triangle measures 95° the other two angles are in a ratio of 7:10 what are the measures of those two angles
Answer:
35 degrees and 50 degrees
Step-by-step explanation:
The sum of all the angles in a triangle must be 180 degrees. So 180 - 95 = 85 leftover for the other two angles. Since we have a ratio of 7:10, we can add that up to get 17 total pieces of that 85-degree angle. 85 / 17 = 5, so each piece is 5 degrees. Therefore, the other two angles are 7*5 = 35 degrees and 10*5 = 50 degrees.
