Answer:
The equation to solve to find the number of yellow marbles =
3y + y = 500
4y = 500
The number of yellow marbles = 125
Step-by-step explanation:
Let the number of
Blue marbles = x
Yellow marbles = y
A large jar contains 500 marbles.
x + y = 500
All of the marbles in the jar are either blue or yellow, and there are 3 times as many blue marbles as yellow marbles.
3y = x
Hence, we substitute 3y for ymx in the above equation
3y + y = 500
4y = 500
y = 500/4
y = 125
The number of yellow marbles = 125

Find a curve that passes through the point (1,5) and has an arc length on the interval [2,6] given by:
6
S2 V1 + 16x dx.
6∫[2,6] (1 + (f'(x))²) dx + 16∫[2,6] x dx = 6S²V1 + 16x dx. To solve this equation, we need additional information about the curve, such as a boundary condition or another equation that relates f(x) and f'(x).
To find a curve that passes through the point (1, 5) and has an arc length on the interval [2, 6] defined by the expression 6S²V1 + 16x dx, we can follow these steps:
Step 1: Determine the general form of the curve equation.
Step 2: Use the arc length formula to obtain an equation involving the curve's equation.
Step 3: Solve the resulting equation to find the specific curve.
Let's proceed with each step:
Step 1: Determine the general form of the curve equation.
Let's assume the curve equation is y = f(x), where f(x) represents the unknown function describing the curve.
Step 2: Use the arc length formula to obtain an equation involving the curve's equation.
The arc length formula for a curve defined by y = f(x) is given by:
S = ∫[a,b] √(1 + (f'(x))²) dx
We are given that the arc length on the interval [2, 6] is defined by the expression 6S²V1 + 16x dx. Substituting the formula for arc length, we have:
6∫[2,6] (√(1 + (f'(x))²))²dx + 16∫[2,6] x dx
Simplifying, we get:
6∫[2,6] (1 + (f'(x))²) dx + 16∫[2,6] x dx
Step 3: Solve the resulting equation to find the specific curve.
Since the expression 6S²V1 + 16x dx represents the arc length on the interval [2, 6], we need to equate it to the arc length formula obtained in Step 2.
6∫[2,6] (1 + (f'(x))²) dx + 16∫[2,6] x dx = 6S²V1 + 16x dx
To solve this equation, we need additional information about the curve, such as a boundary condition or another equation that relates f(x) and f'(x). Without such information, it is not possible to determine the specific curve. Please provide additional constraints or information if available to proceed further in finding the specific curve.

There are 244 seventh grade students. The number of students enrolled in P.E. Is 8 fewer than three times the number of students enrolled in health
Answer:
No. of students enrolled in Health = 63
No. of students enrolled in P.E. = 181
Step-by-step explanation:
Given,
Total students in grade seven = 244 students
A.T.Q.
Let the number of students enrolled in Health be x
so, The number of students enrolled in P.E. = 3x - 8
As we know,
x + (3x - 8) = 244
4x = 244 + 8
x = 252/4
x = 63
Thus, the number of students enrolled in Health = 63
The number of students enrolled in P.E. = 3x - 8
= 3 * 63 - 8
= 189 - 8
= 181 students

A biweekly compounding will generate a higher annual percentage yield ( APY )
than a monthly compounding .
True
False
True. A biweekly compounding will generate a higher annual percentage yield (APY) than a monthly compounding.
True. A biweekly compounding frequency will generate a higher annual percentage yield (APY) compared to a monthly compounding frequency. The APY takes into account the effect of compounding on the total return of an investment over a year.
Biweekly compounding means that interest is calculated and added to the account balance every two weeks, resulting in more frequent compounding periods throughout the year. This more frequent compounding leads to the accumulation of interest on a larger balance, thus generating a higher APY.
On the other hand, monthly compounding occurs once a month, resulting in fewer compounding periods and a lower overall APY. Therefore, for the same nominal interest rate, a biweekly compounding schedule will yield a higher APY compared to a monthly compounding schedule.

You have two unknown integers. Double the larger integer increased by triple the smaller integer is 46. Squaring the larger number and increasing it by four times itself gives the same result as multiplying the smaller number by 20 and adding 5. Use a system to solve for the integers by graphing
The two unknown integers can be found by graphing the given equations. The larger integer is 10, and the smaller integer is 8.
Let's represent the larger integer as 'x' and the smaller integer as 'y.' According to the given information, we have two equations:
Equation 1: 2x + 3y = 46
Equation 2: x^2 + 4x = 20y + 5
To solve this system of equations, we can graph both equations on the same coordinate plane. The point where the two graphs intersect will give us the values of 'x' and 'y' that satisfy both equations simultaneously.
For equation 1, we rearrange it to y = (46 - 2x)/3. Plotting this equation on the graph, we see a straight line.
For equation 2, we rearrange it to x^2 + 4x - 20y - 5 = 0. Plotting this equation, we get a quadratic curve.
By examining the graph, we can see that the two lines intersect at a point where 'x' is approximately 10 and 'y' is approximately 8. Therefore, the larger integer is 10, and the smaller integer is 8.
By substituting these values back into the original equations, we can verify that they satisfy both equations.

a) The mean and standard deviation need to be determined for the given data on the number of ways each sum can be obtained when rolling three dice.
b) A frequency polygon can be drawn to represent the data.
c) Whether the data has a normal distribution or not needs to be determined, and an explanation is required.
a) Mean and Standard Deviation: The mean can be calculated by summing up the products of each value and its corresponding frequency, then dividing by the total frequency. The standard deviation can be calculated by finding the square root of the variance, where the variance is the sum of the squared differences between each value and the mean, divided by the total frequency.
b) Frequency Polygon: A frequency polygon can be plotted by taking the sum values on the x-axis and the corresponding frequencies on the y-axis. Points are plotted for each sum value, and then lines are drawn to connect these points to form the polygon.
c) Normal Distribution: To determine if the data follows a normal distribution, one can visually analyze the frequency polygon. If the polygon displays a symmetric, bell-shaped curve, it suggests a normal distribution. However, if the polygon is skewed or does not exhibit a bell shape, the data is unlikely to have a normal distribution.

The cook at the Elmview School cafeteria made grilled chicken and fried chicken yesterday for lunch. He made 5 pieces of grilled chicken for every 2 pieces of fried chicken.
Pick the diagram that models the ratio in the story.
If the cook made 80 pieces of fried chicken, how many pieces of chicken did he make altogether?
The cook made 280 pieces of chicken altogether.
the diagram is like this :
Grilled chicken: [#####] [#####] [#####] [#####] [#####] ,
Fried chicken: [##] [##]
The ratio of grilled chicken to fried chicken is 5:2, which means for every 5 pieces of grilled chicken, the cook made 2 pieces of fried chicken.
To model this ratio, we can use a bar diagram with five sections for the grilled chicken and two sections for the fried chicken,
If the cook made 80 pieces of fried chicken, we can use this ratio to calculate the number of pieces of grilled chicken.
First, we need to find out how many sets of 5:2 there are in 80. We can do this by dividing 80 by 2 and then multiplying by 5:
80 ÷ 2 = 40
40 × 5 = 200
So the cook made 200 pieces of grilled chicken.
To find the total number of pieces of chicken, we just need to add the grilled and fried chicken together: 200 + 80 = 280 .

There is a 9.52% chance that a random sample of 100 Cal State East Bay students would have the same as our sample's 36 working full-time if exactly 30% of Cal State East Bay students work full-time. There is a 9.52% chance that a random sample of 100 Cal State East Bay students would have more than 30% working full-time.
The correct option id D. There is a 9.52% chance that a random sample of 100 Cal State East Bay students would have more than our sample's 36 working full-time
A study was conducted to determine if more than 30% of Cal State East Bay students work full-time.
The sample of Cal State East Bay students selected was random.
Out of 100 students, 36 were found to be working full-time.
The p-value was calculated to be 0.0952.
The probability of having more than 36 Cal State East Bay students working full-time out of a random sample of 100 students is 9.52% if exactly 30% of Cal State East Bay students work full-time.
Therefore, it is concluded that the null hypothesis cannot be rejected.
The p-value is greater than 0.05 which shows the significance level.
Hence, we accept the null hypothesis.
The null hypothesis states that the proportion of Cal State East Bay students who work full-time is not greater than 30%.
The alternate hypothesis states that the proportion of Cal State East Bay students who work full-time is greater than 30%.
The test is a right-tailed test.
The sample proportion is p = 0.36. The test statistic is given as Z = (p - P0) / √ [P0 (1 - P0) / n]Z = (0.36 - 0.30) / √ [(0.30) (0.70) / 100] = 1.76The p-value is given as 0.0392.
Since the p-value is less than 0.05, we can reject the null hypothesis.
Thus, we can conclude that more than 30% of Cal State East Bay students work full-time.
Hence, option D is the correct answer.
There is a 9.52% chance that a random sample of 100 Cal State East Bay students would have more than 30% working full-time.

Step-by-step explanation:
-12 times 1/3.
It's pretty much just -12x1, then divided by 3.
-12x1 is equal to -12.
Your equation is now simplified, making it easier to solve.
Your equation is: [tex]\frac{-12}{3}[/tex]
-12 divided by 3 is -4, because when a negative number is divided (or multiplied) by a positive number, the quotient (or product) is negative.
-12 x (1/3) = -12/3 = -4.
