Michael’s skateboard was 1 toy out of 50 that Santa had on his sleigh. What percentage is this?

Answer:

500 minutes

Step-by-step explanation:

Let x be the time Ken spends in school.  [I'll note that x < infinity, a common misperception.]

Kevin spends 15% of his school time in science class.  That would be expressed as 0.15x.

We learn that Science class lasts 15 minutes, so we can write:

   0.15x = 75 minutes

          x = (75 minutes)/0.15

          x = 500 minutes is the time Kevin spends in school

=================

(500 minutes)*(1 hr/60 minutes) = 8 1/3 hours

Standardized z score = 2.06

His house rent is not an outlier

Step-by-step explanation:

The mean monthly rent of students at Oxnard university is 970 with a standard deviation of 204. John`s rent is 1390. What is his standardized z-score? Is john`s rent an outlier? How high would the rent have to be to qualify as an outlier

We solve using z score formula

= z = (x-μ)/σ, where

x is the raw score = 1390

μ is the population mean = 970

σ is the population standard deviation = 204

His z score is calculated as:

z = 1390 - 970/204

z = 2.06

No his house rent is not an outlier

The depreciation expense for the year is $260,000. This means that the correct answer is option D: $260,000.

The depreciation expense for the year can be calculated by multiplying the depreciation per unit by the number of units produced. In this case, the depreciation per unit is given as $1.30, and the number of units produced is 200,000.

To find the depreciation expense, we can use the following formula:

Depreciation expense = Depreciation per unit × Number of units produced

Plugging in the values, we have:

Depreciation expense = $1.30 × 200,000

Multiplying, we get:

Depreciation expense = $260,000.

Therefore, the depreciation expense for the year is $260,000. This means that the correct answer is option D: $260,000.

To determine the number of lengths of PVC pipe to be used, we need to divide the total distance to be covered (54 meters) by the length of each PVC pipe (6 meters) and round up to the nearest whole number.

Number of lengths of PVC pipe = Total distance / Length of each PVC pipe

Number of lengths of PVC pipe = 54 meters / 6 meters

Number of lengths of PVC pipe = 9

Therefore, the number of lengths of PVC pipe to be used is 9.

So, the answer is option c. 9.

This value represents the present worth below which the probability is 0.5, indicating a negative present worth.

To estimate the probability that the present worth is negative using the NORM.INV function in Excel,

we need to calculate the present worth of the project and then determine the corresponding probability using the normal distribution.

The present worth of the project can be calculated by finding the sum of the present values of the annual receipts over the 10-year period, minus the initial investment. The present value of each annual receipt can be calculated by discounting it back to the present using the minimum attractive rate of return (MARR).

Using the given information, the present value of the initial investment is $10,000. The present value of each annual receipt is calculated by dividing the expected return of $1,800 by \((1+MARR)^t\),

where t is the year. We then sum up these present values for each year.

We can use the NORM.INV function in Excel to estimate the probability of a negative present worth. The function requires the probability value, mean, and standard deviation as inputs.

Since we have a mean and standard deviation for the present worth,

we can calculate the corresponding probability of a negative present worth using NORM.INV.

This value represents the present worth below which the probability is 0.5. By using the NORM.INV function,

we can estimate the probability that the present worth is negative based on the given data and assumptions.

Algebra is  branch of mathematics that deals with mathematical symbols and rules for manipulating these symbols. It involves use of variables and symbols to represent quantities and use of equations and formulas to solve problems involving these quantities.

To complete the table, we can use the information given in the problem and some basic algebra.

Let's start by finding the total amount of study time, which we can represent with the variable "t". We know that Elizabeth spent 91 minutes, which was 70% of her study time. Using this information, we can write an equation:

0.7t = 91

To solve for t, we can divide both sides of the equation by 0.7:

t = 130

So Elizabeth's total study time was 130 minutes.

Now we can use this information to fill in the table:

The largest taco contained approximately 1 kg of onion for every 6. 6 kg grilled teak. then Amount of grilled steak used: 6.6 (79.17) = 538.356 kg

What is a unit amount in math?

When a price is expressed as a quantity of 1, such as $25 per ticket or $0.89 per can, it is called a unit price. If you have a non-unit price, such as $5.50 for 5 pounds of potatoes, and want to find the unit price, divide the terms of the ratio

1 k + 6.6 k = 617.3

Where “k” is a constant value, a multiplier.

Solving for k:

7.8 k = 617.3

k = 617.3 /7.8  

k= 79.17

The tread life of tires on light-duty trucks follows a normal distribution with a mean of 60,000 miles and a standard deviation of 4,000 miles. We need to determine the likelihood that the mean tire life of a set of four tires falls between 57,000 and 63,000 miles.

Since we are dealing with the mean tire life of a set of four tires, we need to consider the sampling distribution of the sample mean. According to the Central Limit Theorem, when the sample size is large, the sampling distribution of the sample mean will approach a normal distribution, regardless of the shape of the population distribution.

In this case, since the sample size is four, we can assume that the sampling distribution of the sample mean will be approximately normally distributed. The mean of the sampling distribution of the sample mean will be equal to the population mean, which is 60,000 miles.

For the graph: (a)  rate of change of B is -83.9 filings per year.  (b)  Slope is given in the graph (c)  B(0) = 1063 (d) Interpolation is the answer.

(a) Rate of change of BThe rate of change of B can be given by the derivative of the function B(t).B(t) = −83.9t + 1063

Differentiating with respect to time (t), we get:B'(t) = -83.9

This means that the rate of change of B is -83.9 filings per year. Therefore, the answer is "filings per year".

(b) Graph of the model The graph of the model is shown below.

We label the slope on the graph.

(c) Evaluate B(0) B(t) = −83.9t + 1063

Putting t = 0 in the equation above, we get:B(0) = −83.9(0) + 1063 = 1063

Therefore, B(0) = 1063.

(d) Number of bankruptcy filings in 1999 B(t) = −83.9t + 1063

Putting t = 3 in the equation above, we get:B(3) = −83.9(3) + 1063 ≈ 811

Therefore, the number of bankruptcy filings in 1999 is approximately 811.

(d) Interpolation or extrapolationThe data input interval is 1996 through 2000. Since 1999 is within this interval, finding the number of bankruptcy filings in 1999 is interpolation. Therefore, the answer is "interpolation".
