Answer:

Step-by-step explanation 3x=x or 192/64

To solve this word problem, we can set up a system of equations to represent the weight of the crates of onions and green peppers. By finding the weight of the green pepper crate and then subtracting it from the weight of the onion crate, we can determine how many pounds heavier the onion crate is. In this case, the onion crate is 12 pounds heavier than the green pepper crate.

To find out how many pounds heavier the crate of onions is than the crate of green peppers, we need to set up a system of equations. Let's say the weight of the crate of green peppers is x pounds. Then the weight of the crate of onions would be x + 192 ounces. Since 1 pound is equal to 16 ounces, we can convert the weight of the onion crate to pounds by dividing it by 16, giving us x + 12.

The total weight of both crates is 64 pounds, so we can write the equation as x + (x + 12) = 64. Solving this equation, we get 2x + 12 = 64. Subtracting 12 from both sides, we have 2x = 52. Dividing by 2, we find x = 26. Therefore, the crate of green peppers weighs 26 pounds.

To find out how many pounds heavier the crate of onions is than the crate of green peppers, we subtract the weights, which is 26 pounds subtracted from 26 + 12 pounds. This gives us 26 + 12 - 26 = 12 pounds. The crate of onions is 12 pounds heavier than the crate of green peppers.

Answer:

Step-by-step explanation: 23 divided by 8 is 2.875 which means they will each get 2.875 cups

Step 1 : The sample size (n) is 20. The sample mean (x) is 122.2, The Sample standard deviation (s) is  46.245. Step 2: The Critical value (t) is  1.729. Step 3 : Margin of error (E) is 17.220. Step 4 : 90% Confidence interval is (104.98, 139.42) Step 5 : Interpretation: We are 90% confident that the true population mean price of college textbooks purchased in the 2019 - 2020 academic year is between $104.98 and $139.42.

Step 1: Criteria for normality and sample statistics:

To determine if the criteria for approximate normality is met, we need to check if the sample size is large enough (n ≥ 30) or if the data appears to follow a bell-shaped distribution.

Sample size (n) = 20

Sample mean (x) = (65 + 115 + 79 + 109 + 120 + 150 + 119 + 130 + 230 + 145 + 205 + 121 + 69 + 140 + 105 + 99 + 95 + 150 + 145 + 109) / 20 = 122.2 (rounded to one decimal place)

Sample standard deviation (s) = 46.245 (rounded to three decimal places)

Since the sample size is less than 30, we need to check the data's distribution. However, we cannot determine the distribution from the given data alone. We will assume that the textbook prices are normally distributed based on the statement in the problem.

Step 2: Determine the critical value:

We want to construct a 90% confidence interval, so the alpha level is (1 - confidence level) = 0.1. With a sample size of 20, the degrees of freedom (df) is 20 - 1 = 19.

Using a t-table or a t-distribution calculator, the critical value for a 90% confidence level with 19 degrees of freedom is approximately 1.729.

Step 3: Compute the margin of error (E):

Margin of error (E) = t * (s / √(n))

E = 1.729 * (46.245 /√(20))

E = 17.220 (rounded to three decimal places)

Step 4: Construct the 90% confidence interval:

Lower bound = x - E

Upper bound = x + E

Lower bound = 122.2 - 17.220

Lower bound = 104.98 (rounded to two decimal places)

Upper bound = 122.2 + 17.220

Upper bound = 139.42 (rounded to two decimal places)

The 90% confidence interval for the mean price of a college textbook purchased in the 2019 - 2020 academic year is approximately (104.98, 139.42).

Step 5: Interpretation of the 90% confidence interval:

We are 90% confident that the true population mean price of college textbooks purchased in the 2019 - 2020 academic year falls between $104.98 and $139.42. This means that if we were to take multiple samples and construct confidence intervals, approximately 90% of those intervals would contain the true population mean.

The multiple coefficients of determination, R², is 0.7, or 70% evaluated using the formula R² = SSR/SST.

The numerous coefficient of assurance called R-squared (R²), may be a degree of the extent of the full variety within the subordinate variable clarified by the free factors within the relapse demonstrate.

 To calculate R² you can use the following formula:

R² = SSR/SST

where:

SSR is the regression sum of squares.

SST is the sum of squares. This is the regression sum of squares plus the error sum of squares.

In this case SSR = 1400 and SSE = 600. SST can be calculated as:

SST = SSR + SSE

= 1400 + 600

= 2000

Therefore, R² is

R² = SSR/SST

= 1400 / 2000

= 0.7

Therefore, the fold determination coefficient R² is 0.7 or 70%.

Answer:

I would like to say 0.833

Step-by-step explanation:

There are three sections that is split between 3-6. Say the drinks were less than $5, that means 2/3rds of the the drinks are less than $5. 2/3 is 0.666 and no other answers other than D are more than 0.666. Since our value is $5.50 and not $5 it is safe to assume our answer will be larger than 0.666. Using process of elimination your left with answer D. Not an exact explanation but I hope it helps you at least find the answer

Using the uniform distribution, it is found that 0.833 of drinks cost less than $5.50.

An uniform distribution has two bounds, a and b.  

The probability of finding a value of at lower than x is:

\(P(X < x) = \frac{x - a}{b - a}\)

In this problem, the distribution is uniform between 3 and 6, thus \(a = 3, b = 6\).

The proportion of drinks that cost less than $5.50 is:

\(P(X < 5.5) = \frac{5.5 - 3}{6 - 3} = 0.833\)

0.833 of drinks cost less than $5.50.

Step-by-step explanation:

all triangles equal 180 degrees so you would add both angles together then subtract the sum of that by 180

Answer:

\(x=62^o\)

Step-by-step explanation:

Since the addition of all internal angles of a triangle should add up to \(180^o\), then, the missing angle can be found by subtracting the two known angles from \(180^o\):

\(x=180^o-68.5^o-49.5^o=62^o\)

B irrational numbers true or false

The terms in the given equations represent various physical quantities and processes related to the zonal and meridional motion of a fluid.

The term "rho1*∂y/∂p" represents the horizontal pressure gradient force in the meridional direction. It describes the change in pressure with respect to meridional distance and influences the fluid motion. The pressure gradient force acts perpendicular to the isobars (lines of constant pressure) and drives the fluid from regions of high pressure to low pressure.

The term "rho1" represents the density of the fluid, which determines its mass per unit volume. The density influences the magnitude of the pressure gradient force and is typically assumed to be constant in these equations.

The term "∂y/∂p" represents the derivative of meridional distance with respect to pressure. It quantifies the spatial variation of the meridional coordinate as pressure changes. A larger ∂y/∂p indicates a steeper meridional gradient and can result in stronger pressure gradient forces.

The combined term "rho1*∂y/∂p" captures the effect of the pressure gradient force in the meridional direction, driving fluid motion across lines of constant pressure.

In this case, the experimental probability is D. 0.860

First, note that Experimental probability, also known as Empirical probability, is founded on real experiments and adequate documentation of events.

In the table we can see that he rolled the cube 1000 times, and he recorded that 140 of those times he rolled a 5.

Then, the probability of rolling a 5 will be equal to:

P1 = 140/1000 = 0.14

Now, the probabilty of NOT rolling a 5, is equal to the rest of the probabilities, this is:

P2 = 1 - 0.14 = 0.86
