Answer:

A: tom has 15 more roses than ana does.

B: 11:4

Step-by-step explanation:

A: there is a 3:1 and 5:2 ratio of roses to tulips. that means that in tom's, there are 3 roses for every tulip and 5 roses for every 2 tulips in ana's.

we know that they each have 30 tulips so now for Tom.

3:1 so to find roses, we need to multiply the value of tulips to 3.

3×30=90 so we know he has a total of 90 roses.

for ana: she also has 30 tulips. BUT now her ratio is 5:2. so for every 2 tulips she has 5 roses. we need to divide the value of tulips by 2 so 30/2=15 and multiply it by 5, 15*5=75

THAT IS NOT THE ANSWER!! to find the rest of the answer, we have to subtract tom's amount by ana's amount: 90-75=15

B: to find this answer, we have to add all of the roses together and all of the tulips together. roses: 90+75=165. tulips: 30+30=60.

the ratio we get is 165:60. and now we need to simplify it.

Answer:

y = -2x + 9

Step-by-step explanation:

So we know that the line is going down, so that means that slope will be negative. Additionally we know that the y-intercept is 9 because that's where the line crosses the y-axis.

To find slope based on the graph, you can start from the left most point and do rise/run until you get to the next point. In this case, you'd start from (0,9) go down 2 units and over to the right 1, so your Slope is -2/1 or just -2.

So it would be written as y = -2x + 9.

Step-by-step explanation:

If an item is shared in a proportion of 3:4,it means that A gets 3/(3+4) of what is to be shared , that is 3/7 of the bulk item to be shared. B gets 4/(3+4) of what is to be shared, that is 4/7 of the bulk item to be shared.

Also if an item is shared in a proportion of 16:20 , A gets 16/(16+20)=16/36 of Bulk item while B gets 20/(16+20)= 20/36 of the Bulk item being shared.

thats a proportion

A consumer loan of $40,000 with a 15.8% interest rate will require monthly payments over a period of 2 years. The total amount to be paid, including both principal and interest, will be approximately $45,380.

To calculate the monthly payments, we need to determine the total amount to be paid over the loan period, including the principal amount and the interest. The formula used for calculating equal monthly installments is:

M = P * (r * (1 + r)^n) / ((1 + r)^n - 1)

Where:

M = Monthly payment

P = Principal amount

r = Monthly interest rate

n = Number of monthly payments

In this case, the principal amount (P) is $40,000, the interest rate (r) is 15.8% per year, and the loan duration (n) is 2 years (24 months).

First, we convert the annual interest rate to a monthly rate by dividing it by 12: 15.8% / 12 = 0.0132.

Next, we substitute the values into the formula:

M = 40,000 * (0.0132 * (1 + 0.0132)^24) / ((1 + 0.0132)^24 - 1)

Calculating this formula gives us the monthly payment (M) of approximately $1,907.42.

To find the total amount to be paid, we multiply the monthly payment by the number of payments: $1,907.42 * 24 = $45,778.08. However, this includes both the principal and the interest. Subtracting the principal amount ($40,000) gives us the total interest paid: $45,778.08 - $40,000 = $5,778.08.

Therefore, the total amount to be paid, including both principal and interest, will be approximately $45,778.08.

This means the confidence interval for the population mean is approximately (21.135, 23.665).

To construct a confidence interval for the population mean, we can use the formula:

CI =  ± Z * (σ/√n)

Where:

is the sample mean (22.4),

Z is the Z-score corresponding to the desired confidence level (98% corresponds to a Z-score of approximately 2.33),

σ is the population standard deviation (3.8), and

n is the sample size (49).

Plugging in the values, we have:

CI = 22.4 ± 2.33 * (3.8/√49)

Calculating this expression will give us the confidence interval for the population mean. Evaluating the expression, we find:

CI ≈ 22.4 ± 2.33 * 0.543

Simplifying further, we get:

CI ≈ 22.4 ± 1.265

The slope of the new road is zero.

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δx where, m is the slope

Given:

Take points from the Graph (5, 0) and (5, 4).

Slope of a line = m = tanθ

where θ is the angle made by the line with the x−axis.

For a line parallel to y−axis ,θ= π/2.

It will take Jamie 31 months to recoup her investment in the solar panels.

To calculate the time it takes to recoup the investment, we can use the formula for the number of periods needed to reach a future value with compound interest. In this case, the future value is the cost of the solar panels ($33,588.0), and the interest rate is 12% per year, compounded monthly.

We need to find the number of months it takes to reach a future value of $33,588.0 with monthly contributions of $1,200 and a monthly interest rate of 1% (12% divided by 12).

Using the formula for the number of periods (n) needed to reach a future value (FV) with monthly contributions (PMT) and monthly interest rate (r), we have:

FV = PMT * [(1 + r)ⁿ - 1] / r

$33,588.0 = $1,200 * [(1 + 0.01)ⁿ - 1] / 0.01

Solving for n, we find n ≈ 31 months. Therefore, it will take Jamie 31 months to recoup her investment in the solar panels.

Answer:

The radius of sphere with volume 4500 cubic inches is 10.24 inches.

Step-by-step explanation:

Let V be the volume of the sphere

Given

Volume of sphere = V = 4500 cubic inches

Let r be the radius of the sphere

The volume of the sphere is given by the formula

\(V = \frac{4}{3}\pi r^3\)

Putting the known values

\(4500 = \frac{4}{3} * \frac{22}{7} * r^3\\4500 = \frac{88}{21} * r^3\\r^3 = \frac{21}{88} * 4500\\r^3 = 1073.8636\)

Taking cube root on both sides

\(\sqrt[3]{r^3} = \sqrt[3]{1073.8636} \\r = 10.2403\)

Rounding off to nearest hundredth

The radius is: 10.24 inches.

Hence,

The radius of sphere with volume 4500 cubic inches is 10.24 inches.

This leads to the incorrect conclusion that the food is safe for consumption when it is actually not.

A food inspector's job is to inspect samples of food products to determine if they are safe for consumption. In this context, we can consider this process as a hypothesis test with the following hypotheses:

Null hypothesis (H0): The food is safe.
Alternative hypothesis (H1): The food is not safe.

The statement given - "The sample suggests that the food is safe, but it actually is not safe" - describes a situation where the food inspector incorrectly concludes that the food is safe when it is not. This is an example of an error in hypothesis testing.

There are two types of errors in hypothesis testing: Type I and Type II.

Type I error occurs when the null hypothesis is rejected when it is actually true. In other words, a Type I error leads to the false conclusion that the food is not safe when it actually is safe.

Type II error occurs when the null hypothesis is not rejected when it is actually false. In this case, a Type II error results in the false conclusion that the food is safe when it actually is not safe.

Given the statement, "The sample suggests that the food is safe, but it actually is not safe," we can determine that this is an example of a Type II error. The food inspector failed to reject the null hypothesis (that the food is safe) when it was, in fact, false.

a) The 95% confidence interval for the true population proportion of commuters who would use the bus route regularly is estimated to be between 0.243 and 0.497.

b) The manager of the bus company can use this information to assess the potential demand for the commuter bus route and make an informed decision about whether to implement it.

\(\[ \text{Sample proportion} \pm Z \times \sqrt{\frac{\text{Sample proportion} \times (1 - \text{Sample proportion})}{\text{Sample size}}} \]\)

In this case, the sample proportion is 18/50 = 0.36. Using a Z-value corresponding to a 95% confidence level (usually 1.96 for large samples), we can calculate the lower and upper bounds of the confidence interval as follows:

Lower bound = 0.36 - 1.96 × √[(0.36 × 0.64)/50] ≈ 0.243

Upper bound = 0.36 + 1.96 × √[(0.36 × 0.64)/50] ≈ 0.497

Therefore, we can state with 95% confidence that the true population proportion of commuters who would use the bus route regularly falls between 0.243 and 0.497.

If the bus company's goal is to attract a significant number of commuters to make the route financially viable, the manager might consider the lower bound of 24.3% as a baseline estimate. However, if the manager seeks a more conservative approach and wants to minimize the risk of insufficient demand, they could use the upper bound of 49.7% as a more cautious estimate.

By taking into account factors such as operational costs, potential revenue, and market competition, the manager can weigh the potential benefits and risks associated with introducing the commuter bus route. Ultimately, the decision will depend on the manager's tolerance for risk, the company's financial resources, and the overall market demand.
