If the mixing container only holds 40 ounces of paint, then what is the most green paint the artist can make, and what recipe should she use?
Answer:
she can make 40 ounces of green paint
Step-by-step explanation:
20 ounces of yellow paint and 20 ounces of blue paint
The most green paint she can make would be 28 ounce of yellow + 8 ounce of blue which would give us 36 ounce of green paint. Since the container can only hold 40 ounce.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
An artist mixes yellow and blue paint to make the perfect shade of green. She uses 2 ounces of blue paint for every 7 ounces of yellow paint
We need to find the most green paint the artist can make if the mixing container only holds 40 ounces.
Amount of blue paint = 2 ounce
Amount of yellow paint = 7 ounce.
Paint the mixing container can hold = 40 ounce.
Most green paints she can make. This is a ratio question
Yellow green
7 = 2
14 =4
21 =6
28 = 8
35 = 10
Hence, The most green paint she can make would be 28 ounce of yellow + 8 ounce of blue which would give us 36 ounce of green paint. Since the container can only hold 40 ounce.

A trapezoid has an area of 30m^2. if all of its side lengths are tripled, what will its new area be
Answer:
270
Step-by-step explanation:
Because we do not know what the side lengths are, as long as they multiply to 30m^2, it's fine
For this question, let's just say the base is 5, and the height is 6. If we triple 5, we get 15, and if we triple 6, we get 18. 15*18=270
Now what if, the sides are not 5 and 6. Will the area still be the same? Let's find out.
10*3=30 so we can say for this answer, the base is 3, and the height is 10.
10 tripled is 30, and 3 tripled is 9. 30*9=270
So as we look at these 2 answers. we can conclude that the new area, no matter the side lengths, will be 270

Victoria wants to estimate the mean weight of apples in her orchard. She'll sample n apples and make a 95%
confidence interval for the mean weight. She is willing to use 0 = 15 grams as an estimate of the standard
deviation, and she wants the margin of error to be no more than 5 grams.
Which of these is the smallest approximate sample size required to obtain the desired margin of error?
The smallest approximate sample size required for Victoria to estimate the mean weight of apples with a 95% confidence level and a margin of error of no more than 5 grams is 35 apples.
Victoria wants to estimate the mean weight of apples in her orchard with a 95% confidence interval and a margin of error of no more than 5 grams, using an estimated standard deviation of 15 grams. To determine the smallest sample size (n) required, the following formula which incorporates the z-score for the desired confidence level, the standard deviation, and the desired margin of error can be used:
n = (z * σ / E)^2,
where z is the z-score corresponding to a 95% confidence level (which is 1.96), σ (sigma) is the estimated standard deviation (15 grams), and E is the desired margin of error (5 grams).
Plugging the values in gives us: n = (1.96 * 15 / 5)^2 = (1.96 * 3)^2
= 5.88^2 = 34.5744.
Since we cannot have a fraction of an apple, we round up to the nearest whole number. Therefore, the smallest approximate sample size required is 35 apples.
Victoria needs a sample size of at least 35 apples.
Victoria wants to estimate the mean weight of apples in her orchard with a 95% confidence interval and a margin of error no more than 5 grams. We are given the standard deviation of 15 grams.
To find the smallest approximate sample size n, we can use the formula for margin of error (E) in a confidence interval:
E = Z * (σ/√n)
Here, Z is the Z-score for a 95% confidence level, which is 1.96, σ (sigma) is the population standard deviation (15 grams), and n is the sample size.
Rearrange the formula to solve for n:
n = (Z * σ / E)²
Substitute the given values:
Z = 1.96σ = 15 gramsE = 5 gramsCalculate:
n = (1.96 * 15 / 5)²
n = (1.96 * 3)²
n = (5.88)²
n ≈ 34.57
Since the sample size must be a whole number, we round up to the nearest whole number, which is 35. Therefore, Victoria needs a sample size of at least 35 apples to achieve her desired margin of error.

Benito drew a line with a slope of 3. This is determined by using the slope formula and identifying the rate of change in the y coordinates with respect to the x coordinates for each line drawn by the different students.
Explanation:To find the slope of a line on a coordinate plane, we can use the slope formula: slope = (y2 - y1) / (x2 - x1), where (x1, y1) and (x2, y2) are points on the line.
Analise's line goes through points (-3,0) and (0,1). The slope would be (1-0)/(0-(-3)) = 1/3.Benito's line goes through points (0, -1) and (1, 2). The slope is (2-(-1))/(1-0) = 3.Charlie's line is vertical, going through the points (0,-3) and (0,3). Vertical lines do not have a defined slope.Dariya's line passes through (2,3) and (3,0). The slope is (0-3)/(3-2) = -3.Therefore, the student who drew a line with a slope of 3 is Benito.

If one quart bottles of apple juice have weights that are normally distributed with a mean of 64 ounces and a standard deviation of 3 ounces, what percent of bottles would be expected to have less than 58 ounces?
(1) 6.7% (3) 0.6%
(2) 15.0% (4) 2.3%
Answer:
Approximately 2.5%
Step-by-step explanation:
Note that if the mean is 64 oz, then one standard deviation below that would be 61 oz., and two standard deviations beow 64 oz would be 58 oz.
So our task boils down to finding the area under a standard normal curve to the left of 58 oz.
We can do this in two ways.
One is to apply the Empirical Rule, which states that 95% of data lies within 2 standard deviations of the mean, on both sides of the mean. Thus, 5% lies outside the lines representing 2 standard deviations on both sides; half of that (representing the area under the curve to the left of 58) is 2.5%, which is the answer to this question.
The other way is to use a calculator with probability distribution functions built in:
normcdf(-1000, 58, 64, 3) = 0.0228, or approximately 2.28%. Here "-1000,58" represents the area under the curve to the left of 58, 64 represents the mean, and 3 represents the standard deviation.

a. On a coordinate plane, an absolute value function opens down.
The absolute value function f(x)=∣x∣ does not have an inverse that is a function because it fails the horizontal line test.
Specifically, any horizontal line intersects the graph of the absolute value function at most twice.
So, its inverse is not a function.
b. On a coordinate plane, an exponential function increases from quadrant 2 into quadrant 1.
Exponential functions, such as
f(x) = eˣ or f(x) = abˣ, do have inverses that are functions.
They pass the horizontal line test, and their inverses are logarithmic functions.
c. On a coordinate plane, a cubic function has an x-intercept of (0, 0).
A cubic function, such as f(x) = x³, does have an inverse that is a function.
