The probability that a student at certain high school likes art is 36%. The probability that a student who likes art also likes science is 21%. Find the probability that a student chosen at random likes science given that he or she likes art. Round to the nearest tenth of a percent.
Answer: Probability that a student chosen at random likes science given that he or she likes art is 58%
Step-by-step explanation:
Since we have given that
Probability that a student who likes art and science = 21%
Probability that a student who likes art = 36%
According to question,
we need to find the probability that a student chosen at random likes science given that he or she likes art.
So, we will use "Conditional Probability":
P(A) = 0.36
P(S ∩ A) = 0.21
[tex]P(S\mid A)=\frac{P(S\cap A)}{P(A)}\\\\P(S\mid A)=\frac{0.21}{0.36}\\\\P(S\mid A)=0.58\\\\P(S\mid A)=58\%[/tex]
Hence, Probability that a student chosen at random likes science given that he or she likes art is 58%.
Zoe rounded 6 * 8493 to 6 * 8000. Andrew rounded 6 * 8493 + 6 * 9000 who will have an estimate closer to the actual product? How do you know? Explain another way to estimate 6 * 8493 that would give a better estimate
Answer: Zoe is closer to the actual product because 6.80 is closer to 6.8493 than 6.90 mathematically. Another way to estimate 6.8493 is to round to the nearest hundredth place: 6.85
Zoe will have an estimate closer to the actual product.
Explanation:To determine who will have an estimate closer to the actual product, we can compare the rounding methods used by Zoe and Andrew. Zoe rounded 6 * 8493 to 6 * 8000, while Andrew rounded 6 * 8493 + 6 * 9000. In this case, Andrew's estimate will be closer to the actual product because he considered additional terms in his calculation.
Another way to estimate 6 * 8493 that would give a better estimate is to round each term separately before multiplying. For example, rounding 6 to 10 and 8493 to 8500, the estimate would be 10 * 8500 = 85,000.

For every 2 bricks, 5 paving stones were used to build a backyard patio. James used a total of 120 bricks to complete his patio. Of the paving stones be used, 46% were tan in color while the rest were gray. How many gray paving stones were used to build the patio?
162
Step-by-step explanation:... (total paving stones) / bricks = 5 / 2
Multiplying by bricks gives ...
... (total paving stones) = (5/2)·bricks = 5/2·120 = 300
Then the number of gray paving stones is ...
... (gray stones) = (total paving stones) - (tan stones) . . . . tan + gray = total
... = (total paving stones) - 46% · (total paving stones) . . . . tan is 46% of total
... = (100% - 46%)·(total paving stones) = 54% · (total paving stones)
... = 54/100 · 300 . . . . put in the total number of paving stones

Which of the following is equal to cos 35
A) sin 35
B)cos 55
C) sin 55
D) cos 145
Explain why it is equal
Answer:
B) cos 55
Step-by-step explanation:
Consider a right angle triangle with 35 angle, the other angle = 180 - 90 - 35 = 55
sin 35 = opposite side of 35 angle / hypothesis
Opposite side of 35 angle is the same as the adjacent side of 55 angle
sin 35 = adjacent side of 65 angle / hypothesis = cos 55
The answer is B.
John is creating a Thanksgiving display at the store where he works, using only canned pumpkin and canned green beans. He needs to maintain a ratio of pumpkin to green beans of 5 to 1. If he wants to use a total of 114 cans, how many cans of green beans should he use?
Answer:
19
Step-by-step explanation:
The ratio of green beans (g) to pumpkin (p) is ...
... g : p = 1 : 5
Then the ratio of green beans to the total is ...
... g : (g+p) = 1 : (1+5) = 1 : 6
Since you have
... g/total = (1/6)
... g = total · 1/6
you can substitute 114 for the total to find ...
... g = 114 · 1/6 = 19

Identify all the hyperbolas which open horizontally
Answer:
The hyperbolas which open horizontally are:
(x+2)^2/3^2-(2y-10)^2/8^2=1
(x-1)^2/6^2-(2y+6)^2/5^2=1
Step-by-step explanation:
A hyperbola with equation of the form:
(x-h)^2/a^2-(y-k)^2/b^2)=1 opens horizontally
Then, the hyperbolas which open horizontally are:
(x+2)^2/3^2-(2y-10)^2/8^2=1
(x-1)^2/6^2-(2y+6)^2/5^2=1
Answer:
[tex]\frac{(x-2)^2}{3^2}-\frac{(2y-10)^2}{8^2}=1[/tex]
and
[tex]\frac{(x-1)^2}{6^2}-\frac{(2y+6)^2}{5^2}=1[/tex]
Step-by-step explanation:
There are 2 types of hyperbolas:
Horizontal:
[tex]\frac{(x-h)^2}{a^2}-\frac{(y-k)^2}{b^2}=1[/tex]
Vertical:
[tex]\frac{(y-k)^2}{a^2}-\frac{(x-h)^2}{b^2}=1[/tex]
If the x term is positive then parabola is horizontal.
If the y term is positive then parabola is vertical.
so, only first two equations are in which x term is positive.
hence, equations are
[tex]\frac{(x-2)^2}{3^2}-\frac{(2y-10)^2}{8^2}=1[/tex]
and
[tex]\frac{(x-1)^2}{6^2}-\frac{(2y+6)^2}{5^2}=1[/tex]
The cost of a taxi ride is equal to $3.50 plus $0.25 for each mile. If a ride costs a total of $6.75 how long was the ride?
Answer:
13 miles
Step-by-step explanation:
Write and solve an equation involving this information, using x as the distance traveled, in miles:
Cost(x) = $6.75 = $3.50 + ($0.25/mile)x
First, subtract $3.50 from both sides, obtaining: $3.25 = ($.25/mile)x.
Next, divide both sides by $0.25/mile:
$3.25
x = ------------------ = 13 miles
$0.25/mile
The length of the taxi ride was 13 miles.
A Plummer is fixing a pipe with an interior diameter of 0.63 inches. He buys a replacement pipe that must fit inside the old pipe. He uses plumbing tape that will fill 0.15 inches off the space between the two pieces of pipe. The new pipe must be 0.1 inches smaller than the old pipe and tape so that it can fit inside. What is the largest interior diameter pipe he can buy that will still fit inside the old pipe?
The largest interior diameter of the new pipe that would still fit inside the old one is 0.38 inches, after taking into account the thickness of the plumbing tape and additional space requirement.
Explanation:The plumber is attempting to fit a new pipe into an old pipe with an interior diameter of 0.63 inches. We need to take into account the thickness of the plumbing tape that will add an extra 0.15 inches to the diameter, as well as the requirement that the new pipe must be 0.1 inches smaller to fit inside the old pipe.
To calculate the largest interior diameter the new pipe can have, we should do the following:
First, start with the old pipe's diameter, which is 0.63 inches. Deduct the thickness of the plumbing tape. This gives us 0.63 - 0.15 = 0.48 inches. Then, subtract the additional 0.1 inch requirement to provide space for the new pipe to fit. This gives us 0.48 - 0.1 = 0.38 inches.
So, the largest interior diameter of the new pipe that will fit in the old one is 0.38 inches.

An aquarium has a length of n^ 2 +2 inches, a height of n + 5 inches, and a width of 10 inches. What is the volume, in cubic inches, of the aquarium, in terms of n ?
The formula of a volume of a rectangle prism:
[tex]V=lwh[/tex]
l - length
w - width
h - height
We have
[tex]l=n^2+2;\ w = 10,\ h=n+5[/tex]
Substitute:
[tex]V=(n^2+2)(10)(n+5)=(10n^2+20)(n+5)\\\\=(10n^2)(n)+(10n^2)(5)+(20)(n)+(20)(5)\\\\=10n^3+50n^2+20n+100[/tex]
Answer: V = (10n³ + 50n² + 20n + 100) in³The volume of the aquarium in terms of n is calculated by multiplying its length (n2 +2 inches), width (10 inches), and height (n + 5 inches) giving the formula V = (n2 + 2) imes (n + 5) imes 10, which expands to V = 10n3 + 60n2 + 20n + 100 cubic inches.
We use the formula V = length times width times height, where the volume V is the space inside the aquarium. The question provides the dimensions of the aquarium in terms of n: the length (n2 +2 inches), height (n + 5 inches), and width (10 inches).
To calculate the volume, simply multiply the dimensions together:
Length: n2 + 2 inchesHeight: n + 5 inchesWidth: 10 inchesVolume, V = (n2 + 2) imes (n + 5) imes 10
Expanding the expression gives us the volume V in cubic inches as a function of n:
V = 10n3 + 60n2 + 20n + 100 cubic inches

Write an equation in slope-intercept form for the line that has a slope of -4 and passes through (1, 2).
A. y = -2x + 4
B. y = -4x + 2
C. y = -4x + 6
D. y = -4x + 9
y-y1 = m(x-x1) ..... point slope form
y-2 = -4(x-1) ... plug in the given info; solve for y
y-2 = -4x+4
y = -4x+4+2
y = -4x+6
Answer is choice C
Answer:
C. y = -4x + 6
Step-by-step explanation:
First write it in point-slope form ( because that is what you are given):-
y - y1 = m(x - x1):-
y - 2 = -4(x - 1)
y - 2 = -4x + 4
y = -4x + 6 (answer)
Write the equation of a line that passes through the points (0, -2) and (4, -5). Answer MUST be in standard form: Ax + By = C.
The slope-intercept form:
[tex]y=mx+b[/tex]
m - slope
b - y-intercept → (0, b).
We have the points (4, -5) and (0, -2) → y-intercept → b = -2.
The formula of a slope:
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
Substitute:
[tex]m=\dfrac{-2-(-5)}{0-4}=\dfrac{-2+5}{-4}=\dfrac{3}{-4}=-\dfrac{3}{4}[/tex]
Therefore we have the equation of a line
[tex]y=-\dfrac{3}{4}x-2[/tex]
Convert to the standard form: [tex]Ax+By=C[/tex]
[tex]y=-\dfrac{3}{4}x-2\qquad\text{multiply both sides by 4}\\\\4y=-3x-8\qquad\text{add 3x to both sides}\\\\\boxed{3x+4y=-8}[/tex]
So for this, I will be putting the equation into slope-intercept form then rearranging it into standard form. Firstly, we need to solve for the slope. To do this, take the 2 coordinates given to us and solve as such:
[tex]\frac{-5-(-2)}{4-0}=-\frac{3}{4}[/tex]
Now, one of the coordinates given to us is (0,-2), which is the y-intercept. With all this info, our slope-intercept equation is [tex]y=-\frac{3}{4}x-2[/tex] . From here we can solve for the standard form.
Firstly, add 3/4x onto both sides of the equation:
[tex]\frac{3}{4}x+y=-2[/tex]
Now, it may appear that we are finished. However, 3/4 is not an integer (Integers are whole numbers). To make it an integer, we need to multiply both sides by 4:
[tex]3x+4y=-8[/tex]
Answer:In short, the standard form of this equation is 3x + 4y = -8.

Find the slope-intercept form of the line passing through the point (7,-2) and parallel to the line y=-8x-4.
The slope-intercept form of the line passing through the point (7, -2) and parallel to the line y = -8x - 4 is y = -8x + 54. The required answer is y = -8x + 54.
To find the slope-intercept form of a line parallel to the given line, we need to determine the slope of the given line first.
The given line has a slope of -8 since it is in the form y = mx + b, where m represents the slope.
Since the line we are looking for is parallel to the given line, it will have the same slope of -8.
Now, we can use the point-slope form of a linear equation to find the equation of the line passing through the point (7, -2) with a slope of -8:
y - y1 = m(x - x1)
Substituting the values of the point and slope:
y - (-2) = -8(x - 7)
Simplifying:
y + 2 = -8x + 56
Rearranging the equation to the slope-intercept form:
y = -8x + 54
Therefore, the slope-intercept form of the line passing through the point (7, -2) and parallel to the line y = -8x - 4 is y = -8x + 54. The required answer is y = -8x + 54.

A student has 20 pencils at the beginning of the school year. After a week, the student has 18 pencils left. If the student continues to use pencils at the same rate, which equation will represent pencils left after w weeks?
Answer: p = -2w + 20
Step-by-step explanation:
If the student had 20 pencils but now has 18 pencils, he uses pencils at a rate of 2 per week. So, m = -2 (negative because he is decreasing the amount of pencils). The student started with 20 pencils so b = 20
Use the y = mx + b but replace "y" with "p" and replace "x" with "w" and input the m and b as stated above:
p = -2w + 20
There is a line whose slope is 0 and whose y -intercept is 9. What is its equation in slope-intercept form?
Answer:
y = 0x + 9
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y-intercept )
here m = 0 and c = 9, hence
y = 0x + 9
The equation of a horizontal line is normally written as y = 9
with the x- term omitted
The equation of a line with a slope of 0 and a y-intercept of 9 is y = 9, which represents a horizontal line on the graph.
The student is asking about the equation of a line in slope-intercept form, which is y = mx + b, where m is the slope and b is the y-intercept. Given that the slope (m) is 0, and the y-intercept (b) is 9, the equation of the line is simply y = 0x + 9. Since any number multiplied by zero is zero, this simplifies to y = 9.
Therefore, the equation of the line with a slope of 0 and a y-intercept of 9 in slope-intercept form is y = 9. This represents a horizontal line that crosses the y-axis at 9.
