What is Mara has 7 cups of green paint and a container filled with 64 fluid ounces of yellow paint which color of paint does Mara have a lot of explain your reasoning
Answer: Mara has a lot of yellow paint
Step-by-step explanation:
Mara has less green paint because 7 cups is the same as 56 fluid ounces and 56 is less than 64 (yellow paint)
Mara has 56 fluid ounces of green paint and 64 fluid ounces of yellow paint. Therefore, Mara has more yellow paint. The calculations involve converting units of measure for an accurate comparison.
Explanation:To answer your question accurately, it would be necessary to convert the measurements to the same unit. Given that 1 cup is approximately 8 fluid ounces, Mara's 7 cups of green paint convert to 56 fluid ounces (7 cups * 8 ounces/cup).
Comparing this to the 64 fluid ounces of yellow paint, we find that Mara has more yellow paint.
The comparison was made by first converting the quantity of green paint from cups to fluid ounces for a direct, accurate comparison between the two quantities of paint. This kind of problem is a great example of why understanding units of measure is important in mathematics and in everyday life.

18
Answer:
The equation of the hypotenuse line is y = -3·x + 9
Therefore, the correct options are -3 and 9
Step-by-step explanation:
The question asks to fill the boxes
y = _ x + _
We note that the equation is that of a straight line of the form;
y = m·x + c
Where:
m = Slope of the straight line graph and
c = Y intercept, that is the y-coordinate of the point on the line where x = 0
From the graph, we find the slope as follows;
[tex]Slope = \frac{y_2 - y_1}{x_2 -x_1} = \frac{(-9) -0}{6-3} = -3[/tex]
Therefore, m = -3
The y intercept is found by extending the hypotenuse line to the point where it touches the y axes that is at x = 0;
From the graph, it is observed that the line, when extended, touches the y axes at the point y = 9, therefore, c = 9
Hence we have, the equation of the hypotenuse line is y = -3·x + 9.
Answer:
y = -3x + 9

A.
an arrangement in which you receive money, goods, or services now in exchange for the promise of payment later
B.
an arrangement in which you receive goods or services in exchange for other goods and services
C.
an arrangement in which you receive money now and pay it back later with fees
I need the answer ASAP!!!! A.K.A. Right Now:(
Answer:
ypur answer would be a.
Credit is an arrangement where goods, services, or money are provided in the present with the promise of future payment, typically going into debt.
Credit is an arrangement where you receive money, goods, or services now and agree to pay for them later. This includes transactions with a credit card, where you obtain a good or service without immediate payment, but with a promise to pay the credit card company later, often with interest. Credit transactions essentially involve going into debt, as they create an obligation to pay in the future.
Choosing the correct answer from the provided options:
An arrangement in which you receive money, goods, or services now in exchange for the promise of payment later.
An arrangement in which you receive goods or services in exchange for other goods and services.
An arrangement in which you receive money now and pay it back later with fees.
The correct answer would be (A) since it entails receiving money, goods, or services now with the promise of payment at a later date, which matches the definition of a credit transaction.

Which statement can be used to create her list?
A: StartRoot 0.8 EndRoot is less than Four-fifths because 0.8 = four-fifths and the square root of a number less than 1 is less than the number itself.
B: StartRoot 7 EndRoot is greater than StartRoot 7 squared EndRoot because StartRoot 7 squared EndRoot = 7 and the square root of a number greater than 1 is greater than the number itself.
C: (StartRoot 5 EndRoot) squaredis less than StartRoot 7 EndRoot because (StartRoot 5 EndRoot) squared = 5 and StartRoot 7 EndRoot is between 6 and 8.
D: StartRoot 7 EndRoot is greater than Four-fifths because Four-fifths is less than 1 and the square root of a number greater than 1 is greater than 1.
Answer:
The correct option is D
Step-by-step explanation:
The given numbers are
√(7²), √7, 4/5, √0.8, (√5)²
Now, let us check their real values.
√(7²) = 7
√7 ≈ 2.646
4/5 = 0.8
√0.8 ≈ 0.894
(√5)² = 5
Now, checking the options,
A doesn't apply
B doesn't appy
C doesn't apply
D applies because √7 = 2.646 is greater than 4/5 = 0.8 because 4/5 is less than 1 and the square root of a number greater than 1 is greater than 1.

By mistake, you added salt instead of sugar to the
oil. How can you remove the salt?
Answer: Evaporate the water by boiling it in a pot with a lid or another container. This separates both substances as the boiling point for water is much lower than salt, this method is called simple distillation.
Answer:
Salt is ionic, and oil is covalent. If you add water, the salt will dissolve in the water, and the oil will float to the top. You could then skim the oil and start over with sugar. To double-check, you could even make sure the oil does not conduct electricity!

Tony flips a coin and gets heads. He tells his friend that he can get heads two more times in a row .what is the probability that tony will flip a coin and get heads three times in a row
Answer:
The probability is 1/8 or 0.125
Step-by-step explanation:
In this question, we are concerned with calculating the probability that when a coin is flipped there would be a show of heads three times.
In flipping of a coin, there are only two possible results with equal probability. The probability of both events i.e P(H) and P(T) is equal and that is 1/2
Thus the probability of getting heads three times in a row will be P(HHH) meaning P(H) and another P(H) and another P(H)
When we have and in a probability question, that means we are to multiply the probabilities together.
Hence, P(HHH) = 1/2 * 1/2 * 1/2 = 1/8

The volume of a rectangular prism is represented by the function x^3+9x+6x-16.The length of the box is x+2, while the height is x+8. Find the expression representing the width of the box
Answer:
Width = (x -1)
Step-by-step explanation:
Volume of rectangular prism = x³ + 9x² + 6x - 16
length * height *width = x³ + 9x² + 6x - 16
(x + 2)(x + 8 )* width = x³ + 9x² + 6x - 16
When Samuel commutes to work, the amount of time it takes him to arrive is normally distributed with a mean of 32 minutes and a standard deviation of 5 minutes. Using the empirical rule, what percentage of his commutes will be between 17 and 47 minutes?
Answer:
[tex]z=\frac{x-\mu}{\sigma}[/tex]
And we can find the nnumber of deviations from the mean for each limit given:
[tex] z_1 = \frac{17-32}{5} = -3[/tex]
[tex] z_2= \frac{47-32}{5} = 3[/tex]
So we are 3 deviation from the mean and using the empirical rule we know that within 3 deviations from the mean we have 99.7% of the values
Step-by-step explanation:
Let X the random variable that represent the amount of time it takes him to arrive, and for this case we know the distribution for X is given by:
[tex]X \sim N(32,5)[/tex]
Where [tex]\mu=32[/tex] and [tex]\sigma=5[/tex]
We want to find this probability:
[tex]P(17<X<41)[/tex]
And we can use the z score formula given by:
[tex]z=\frac{x-\mu}{\sigma}[/tex]
And we can find the nnumber of deviations from the mean for each limit given:
[tex] z_1 = \frac{17-32}{5} = -3[/tex]
[tex] z_2= \frac{47-32}{5} = 3[/tex]
So we are 3 deviation from the mean and using the empirical rule we know that within 3 deviations from the mean we have 99.7% of the values

What is the probability that a data value in a normal distribution is between a z-score of -0.28 and a z-score of 0.64? Round your answer to the nearest tenth of a percent. A. 90.9% B. 58.1% C. 34.9% D. 73.3%
Answer:
[tex]P(-0.28 <Z< 0.64) = P(Z<0.64) -P(Z<-0.28)[/tex]
[tex]P(Z<0.64) =0.739[/tex]
[tex]P(Z<-0.28) =0.390[/tex]
And with the difference we got: 0.739-0.390 = 0.349
And if we convert the probability to % we got 0.349*100 = 34.9%. And the best answer would be:
C. 34.9%
Step-by-step explanation:
For this case we want this probability:
[tex] P(-0.28 <Z< 0.64)[/tex]
And we can find this probability using the normal standard distribution and with the following difference:
[tex]P(-0.28 <Z< 0.64) = P(Z<0.64) -P(Z<-0.28)[/tex]
If we find the individual probabilities we got:
[tex]P(Z<0.64) =0.739[/tex]
[tex]P(Z<-0.28) =0.390[/tex]
And with the difference we got: 0.739-0.390 = 0.349
And if we convert the probability to % we got 0.349*100 = 34.9%. And the best answer would be:
C. 34.9%
The probability of a value falling between z-scores of -0.28 and 0.64 in a normal distribution is found by taking the cumulative area under the standard normal curve for each z-score and calculating their difference, which results in approximately 34.9% after rounding. Thus, the correct answer to the student's question is option C) 34.9%.
The question addresses the calculation of probabilities for specific ranges of z-scores in a normal distribution. To find the probability that a data value is between a z-score of -0.28 and a z-score of 0.64, we need to look at the standard normal distribution table or use a statistical software that provides the cumulative area up to these z-scores.
The probability of a value being less than z = 0.64 is P(Z < 0.64). According to the z-table, this probability is approximately 0.7389. Similarly, the probability of a value being greater than z = -0.28 (which is equivalent to less than due to symmetry) can be found as 1 - P(Z < -0.28), which, when referred to a z-table, gives a value of about 0.6103. Therefore, the total probability of a value being between z = -0.28 and z = 0.64 is the difference between these two probabilities, 0.7389 - (1 - 0.6103) = 0.3492 or 34.92%.
However, this value needs to be rounded to the nearest tenth of a percent, which yields 34.9%. So the correct answer is C. 34.9%.
