Identify the cross section that results from slicing the three-dimensional figure.
A)
pyramid
B)
prism
C)
square
D)
triangle
Answers
Explanation:
You have the correct answer. The blue plane is basically a knife that cuts the pyramid into two pieces. The top portion is a smaller similar pyramid (same shape, smaller size). The bottom portion is a pyramidal frustum.
Where the cut happens in the blue plane, a square forms. This square is the base of the upper pyramid and the roof of the frustum.
We can think of the blue stuff like water. Then allow that water to freeze to form a block of ice. Then carefully slide the block of ice upward and there should be a square hole in the center. So this is another way to see how we have a square cross section. The square cross section is due to the pyramid's base being a square. This means that if we had say a hexagonal base, then the cross section would be hexagonal.
All of this only applies if the cutting plane is parallel to the base of the pyramid.

Answers
Answer:
f(x)=-8(x^2)+6
Step-by-step explanation:
f(x)=a(x-h)+k is the vertex formula since we are given the vertex and a point.
substituting the given information, we get: f(x)=a((x-0)^2)+6, and then -2=a((-1-0)^2)+6 to get -2=a+6, or a=-8.
Answer:
-8x^2+6
Step-by-step explanation:
substitute in quadratic function: f(x)=ax^2+bx+c. 6=c because when x=0, f(x)=6. it is the y-intercept. but because h=-b/2a and 0=-b/2(8), b=0.
Jenna has 3 red balloons and 5 blue balloons.
The ratio of the number of red balloons to the number of blue balloons is (_____) . She adds 2 red balloons and removes 1 blue balloon. The new ratio of the number of red balloons to the number of blue balloons is (______).
Answers
Answer: First answer: 3 : 5. Second answer: 5 : 4
Step-by-step explanation: Since it says red balloons to blue balloons, the number of red balloons comes first, so its 3 : 5. For the second one, add two to the amount of red balloons and take one from the amount of blue balloons and you get 5 : 4. I hope this helps!

X^2-21x
Answers
Answer:
110.25
Step-by-step explanation:
Consider the square ...
(x +a)^2 = x^2 +2ax +a^2
The added constant (a^2) is the square of half the x-coefficient:
a^2 = ((2a)/2)^2
__
The added constant needs to be the square of half the x-coefficient:
c = (-21/2)^2 = 441/4 = 110.25
__
x^2 -21x +110.25 = (x -10.5)^2

Step-by-step explanation:
Find the total number of jellybeans.
10 + 6 + 4 = 20
Find the probability of selecting a yellow jellybean
(p yellow) = 10/20
reduce by 10
(p yellow) = 1/2
Find the probability of selecting a red jellybean
(p red) = 6/20
reduce by 2

Find x and then Find y
Answers
Answer:
x=45
y=30
Step-by-step explanation:
We know that there are two isosceles triangles which means two of the angles in the triangle are equivalent. We can use this to first solve for x
180-90=2x (This is for the smaller triangle)
90=2x
x=45
Now we find the measure of the angle in the bigger triangle.
(180-30)/2=150/2=75
Since y+x=75
y=75-x
y=75-45
y=30
Answer:
x=45y=30
Step-by-step explanation:
since its a triangle the corner have to be 75 each and the only way that the smaller circle sums to 180 is if X= 45 then 75-45=30

Test has a mean of 40, standard deviation of 10. What is the percent of people with a
score below 37?
Answers
Answer:
97.275% or 97.5%, depending on the precision desired.
Step-by-step explanation:
In a normal distribution, approximately 68% of scores are within 1 standard deviation of the mean; half of these (34%) are above the mean, and the other half are below the mean. Approximately 95% (more accurately, 95.45%) of results are within 2 standard deviations of the mean, including those 68% that are within 1 standard deviation.
Since our standard deviation is 20, and we are asked what percentage are below 140 (which is 2 standard deviations above the mean of 120), we are essentially being asked to find what percentage of scores are not above 140, which would equal 100% - (percent of scores above 140).
If 95.45% of scores are within 2 SD of the mean, then approx 4.55% are outside of that range. Of these, half will be more than two standard deviations below the mean (i.e. less than 60), and half will be more than 2 standard deviations above the mean (i.e. greater than 140). Thus to find the percent of scores greater than 140, we will divide 4.55 by 2, coming up with approx 2.725%.
Then, the percent of results below 100% will simply be 100%-2.725% = 97.275%.
Of note, many worksheets, teachers, and textbooks will allow you to simply round that 95.45% I mentioned earlier to 95%, following the 68/95/99.7 rule (e.g. 68% of the data is within 1 SD, 95% within 2 SD, and 99.7% within 3 SD of the mean). If you are instructed to do this, then in the problem above we would say 5% lies more than 2 SD away from the mean, and half of those (2.5%) lie more than 2 SD above the mean. Thus the percentage below 140 in this case would be 100%-2.5% = 97.5%.
