Using it's concept, it is found that of the students who like the vegetables on their pizza, the percentage that do not like meat is of 76.19%.
What is a percentage?The percentage of an amount a over a total amount b is given by a multiplied by 100% and divided by b, that is:
[tex]P = \frac{a}{b} \times 100\%[/tex]
In this problem, we have that:
105 students like vegetables on their pizza, hence b = 105.80 do not like meat, hence a = 80.Thus, the percentage is given by:
[tex]P = \frac{80}{105} \times 100\% = 76.19\%[/tex]

Answer:
One solution
(2,0) is the point
Step-by-step explanation:
If the graphs of the equations intersect, then there is one solution that is true for both equations.
When the lines intersect, the point of intersection is the only point that the two graphs have in common, so the coordinates of that point are the solution for the two variables used in the equations.
The point of intersection is (2,0), because that is the point that both lines intersect at.

27) Jim and his uncle went to the circus. Together they spent $30, 4/15 of that for a bus ride, 2/5 for food, 7/30 for tickets, and the rest on souvenirs. What part of their money did they spend on souvenirs?
Answer:
3 dollars
Step-by-step explanation:
4/15 of 30 = $8
2/5 of 30 = $12
7/30 of 30 = $7
8 + 7 + 12 = $27
30 - 27 = $3
They only had 3 dollars left after spending everything else they had.
Answer:
3/30
Step-by-step explanation:
4/15 so times 15 by 2 and 4 by 2 to get 8/30
leave 7/30 alone
2/5 five times 6 is 30, since you multiplied 5 by 6 you have to do 2 x 6 which is 12, 12/30
now you can add bc a common denominator 12 + 7 + 8 = 27
30 - 27 = 3, so 3/30ths was spent on souvenirs.
The mean can be found when you add all the numbers in a set, and then divide that sum by the amount of numbers given. Find the average tree growth of four Douglas Fir trees: 2.2 in., 1 1/5 in., and 1 1/2 in.
Answer:
49/30
Step-by-step explanation:
To find the mean, add up 2.2 + 1 1/5 + 1 1/2 to get 49/10
Then divide that by 3 (it says four Douglas trees but you only put 3 types)
49/10 divided by 3 is 49/10 times 1/3, which is 49/30

The graph looks like an absolute function.
If we were to compare the function [tex]y= |x|[/tex] to this graph (see image attached), we see that the function in the graph has only shifted two to the right.
To write in function form, when shifting the graph horizontally
add within the function --> move the graph to the leftsubtract from within function --> move the graph to the rightIn this case, since we want to shift over two spots horizontally, we get the function is
y = |x -2|
Now we want to find the function that is increasing and decreasing over the same interval.
The only function that looks the most similar is y = 4|x-2|.
The reason for that is because the y = 4|x-2| is just a stretched version of y= |x-2| meaning the point where it is increasing or decreasing should stay the same. Look at the second image I attached.

Find an equation for the parabola with focus (-4, 0) and directrix x=4.
HELP!
Answer:
[tex]y = - \frac{ {x}^{2} }{16} [/tex]
Step-by-step explanation:
First, notice the diretcrtirx is a negative horinzontal lie so this means we have a parabola facing downwards
Equation of a Parabola with center (h,k) >
[tex](x - h) {}^{2} = - 4p(y - k)[/tex]
Where p is the distance of the vertex to focus/ or distance to vertex to directrix
This emans that the vertex is halfway of (-4,0) and x=4.
Since this is a upwards parabola, the y value that lies on focal axis doesn't change so know this means that
The vertex is halfway between (-4,0) and (4,0).
So the vertex is (0,0).
Plugging that in we get,
[tex] {x}^{2} = - 4py[/tex]
The distance to the vertex or either the focus or directrix is 4 so p=4
[tex] {x}^{2} = - 4(4)y[/tex]
[tex] {x}^{2} = - 16y[/tex]
[tex]y = - \frac{ {x}^{2} }{16} [/tex]

What is Statistic?A statistic is a piece of data derived from a subset of a population. It's the inverse of a parameter — census data, which polls everyone.
Statistics is a method of comprehending data collected about us and the world.
Here, a negatively skewed (also known as left-skewed) distribution is a sort of distribution in which more values are concentrated on the right side (tail) of the distribution graph while the left tail of the distribution graph is longer.
Thus, the distribution (D) is negatively skewed
Hence, the correct answer is an option (D).

Answer:
y = -2x + 5

to figure this out you may plug this equation into y = mx + b with b being the unknown
this goes to
-7 = -2(6) + b
then multiply 6 to -2
-7 = -12 + b
then add 12 to both sides
5 = b

Carmen deposited $6,000 into a savings account that earns 2.8% interest compounded annually. How much will she have in her account (total) at the end of 3 years?
To help Carmen find the total after 3 years
We'll have to use the annual compound interest formula: A = P(1 + r)ⁿ
A = Final balance (?)
P = Principal balance (6000)
r = Rate (0.028)
n = years (3)
A = 6000(1 + 0.028)³
A = 6000(1.028)³
A = 6000(1.086373952)
A = 6518.243712
Round that to the nearest cent, and we get $6,518.24 as the answer.

Ruchi measured the area of her kitchen as 2. 81 times 10 Superscript 4 square units. When she recorded the area, she wrote 2. 81 times 10 Superscript 4 square feet. Which statement about her labeling of the units is true? She is correct because dimensions of rooms must always be measured in feet and area would be square feet. She is correct because 2. 81 times 10 Superscript 4 ftSquared is equivalent to 2, 810 ftSquared, which is an average size for a kitchen since area is always so much more than length. She is incorrect because 2. 81 times 10 Superscript 4 is around 30,000 so the units must be smaller than feet. She most likely measured in inches. She is incorrect because 2. 81 is a small number. She probably measured in yards to arrive at such a small value.
Ruchi is incorrect because 2.81×10⁴ is around 30,000. so the units must be smaller than feet.
What is Units conversion?Unit conversion is a way of converting some common units into another without changing their real value. for, example, 1 centimetre is equal to 10 mm, though the real measurement is still the same the units and numerical values have been changed.
As it is given that the measurement that Ruchi wrote is 2.81×10⁴ ft². And, the area of 2.81×10⁴ ft² is 28,100 ft² which is nearly 30,000 ft², while the size of an average house is 2,300 ft². Therefore, the area that is written by Ruchi is too big compared to an average kitchen.
Hence, Ruchi is incorrect because 2.81×10⁴ is around 30,000 so the units must be smaller than feet.
