Answer: To find Janice's running speed, we need to determine how many miles she runs per hour.

We know that the track is 1/4 mile long and Janice can complete each lap in 1/10 of an hour. To find the total number of miles Janice runs in an hour, we can multiply the length of the track by the number of laps she completes in an hour.

Length of the track * number of laps = total miles

1/4 mile * (1/10 hour)^-1 = total miles

On the second equation, we are using the inverse of the time, to get the number of laps completed in an hour

The speed is distance over time, so we need to express the distance in miles and the time in hours.

So Janice's running speed is 4 miles/hour.

Step-by-step explanation:

The normal probability statement that corresponds to the binomial probability statement "P(x < 131)" after applying the continuity correction is D. P(x < 131.5).

To apply the continuity correction, we add and subtract 0.5 to the value of 131, which gives us 130.5 and 131.5. This adjustment accounts for the fact that the binomial distribution is discrete, while the normal distribution is continuous.

Now, we need to determine which of the following options corresponds to the binomial probability statement "P(x < 131)" after applying the continuity correction:

D. P(x < 131.5): This option represents the probability of having fewer than 131.5 successes, including 131 successes. It aligns with the original binomial probability of having fewer than 131 successes, so this could be a potential candidate.

Hence the correct option is (d).

The missing factor in the second equation is 1, and the completed equation is: -24y + (-5) = -4(6y + 5/4)

We know that the GCF of -24y and -20 is 4. To find the missing factor in each equation, we can divide both terms by the GCF of 4.

For the first equation, we have:

-24y = 4 * (-6y)

Dividing both sides by 4, we get:

-6y = -24/4

Simplifying, we get:

-6y = -6

Therefore, the missing factor in the first equation is -1, and the completed equation is:

-24y + 20 = -4(6y - 5)

For the second equation, we have:

-20 = 4 * (-5)

Dividing both sides by 4, we get:

-5 = -20/4

Simplifying, we get:

-5 = -5/1

Therefore, the missing factor in the second equation is 1, and the completed equation is:

-24y + (-5) = -4(6y + 5/4)

because 7 in 468.705 has value 1/10

1/100×1/100 is 1/1000 which is 0.007.

Answer:

B. 695.187

Explanation:

In the number 468.705, the number 7 is in tenths place (0.1)

If the value of 7 in that number which is 0.1 has value of 1/100, then

0.1 × 1/100 = 0.001  (thousand place)

Answer:

Step-by-step explanation:

I can explain if you need. Write in comments if you do need.

Answer:  B) Flipping a coin.

Step-by-step explanation: Flipping a coin could not be used to simulate choosing a fruit oatmeal because it only has two possible outcomes: heads or tails. This is not enough to represent the four flavors of oatmeal: apple, banana, maple, and plain. A simulation needs to have the same number of outcomes as the event it is modeling.

The other answers are incorrect because they could be used to simulate choosing a fruit oatmeal by assigning each flavor to a different outcome. For example:

A) 1 or 2 when tossing a number cube. This could be used by assigning apple to 1, banana to 2, maple to 3 or 4, and plain to 5 or 6.

C) A spinner with 8 equal sections: A, B, C, D, E, F, G, H. This could be used by assigning apple to A or B, banana to C or D, maple to E or F, and plain to G or H.

D) The digits 5-9 for a random digit generator. This could be used by assigning apple to 5, banana to 6, maple to 7 or 8, and plain to 9.

To elaborate the explanation, I will add some more details and examples to clarify the concept of simulation.

A simulation is a way of imitating or mimicking a real-world situation or event using a model that has similar characteristics and behaviors. A simulation can help us study, analyze, predict, or test something that is too complex, expensive, dangerous, or impractical to do in reality.

For example, suppose we want to know how likely it is to get a fruit oatmeal when we buy one at random from a store that sells four flavors: apple, banana, maple, and plain. We could do an experiment by buying many oatmeals and recording the flavors we get, but this would be costly and time-consuming. Instead, we could use a simulation by using a device or a tool that has four equally likely outcomes and assigning each outcome to a flavor. Then we could repeat the simulation many times and record the results. This would give us an estimate of the probability of getting a fruit oatmeal.

One way to do a simulation is to use a random number generator (RNG), which is a device or a program that produces numbers that are unpredictable and have no pattern. A RNG can have different types of outputs, such as digits, letters, symbols, colors, etc. For example, we could use a RNG that produces digits from 0 to 9 and assign apple to 0 or 1, banana to 2 or 3, maple to 4 or 5, and plain to 6 or 7. Then we could ignore the digits 8 and 9. This way, each flavor has a 2/8 or 1/4 chance of being chosen.

Another way to do a simulation is to use a physical object that has different outcomes that are equally likely. For example, we could use a number cube (also known as a die) and assign apple to 1 or 2, banana to 3 or 4, maple to 5 or 6, and plain to none. Then we could roll the number cube many times and record the results. This way, each flavor has a 2/6 or 1/3 chance of being chosen.

A third way to do a simulation is to use a spinner that has different sections that are equally sized. For example, we could use a spinner that has eight sections labeled A, B, C, D, E, F, G, H and assign apple to A or B, banana to C or D, maple to E or F, and plain to G or H. Then we could spin the spinner many times and record the results. This way, each flavor has a 2/8 or 1/4 chance of being chosen.

However, not every device or tool can be used for a simulation. For example, flipping a coin cannot be used to simulate choosing a fruit oatmeal because it only has two possible outcomes: heads or tails. This is not enough to represent the four flavors of oatmeal.

The amplitude is 2, the phase shift is 2/3 to the right, and the period is 2π/3.

Given the function y = -2 sin(3x - 2) + 2, you can determine the amplitude, phase shift, and period using the following information:

Amplitude: The amplitude is the absolute value of the coefficient in front of the sine function. In this case, it is |-2| = 2.

Phase shift: The phase shift is determined by the value inside the parentheses of the sine function, which is (3x - 2). To find the phase shift, set the expression inside the parentheses equal to zero and solve for x: 3x - 2 = 0. Solving for x gives x = 2/3. The phase shift is 2/3 to the right.

Period: The period is the length of one complete cycle of the sine function. To find the period, divide 2π by the coefficient of x inside the parentheses. In this case, the period is 2π/3.

$146250 Akeo will earn his fifth year since he acquires 45 percent of the market.

Rather than being expressed as a fraction, a percentage is a piece of a whole expressed as a number between 0 and 100. Nothing is zero percent; everything is 100 percent; half of something is 50 percent; and nothing is zero percent.

Given, A pet grooming shop has been established by Akeo Goto. He calculates that the local pet grooming sector generates around $325,000 in annual sales. In the town, there are two other pet-grooming shops.

Since Akeo goto acquires 45% of the market in the fifth year.

Thus his revenue for fifth year = 45% of  325000

his revenue for fifth year = (45*325000)/100 = 146250

First, we test each option to determine the true and false options.

(a) S, V and U are collinear

Points that are collinear are on the same line

S, V and U are not collinear, because they are not on the same line.

Hence, (a) is false

(b) Q, S, T and U are coplanar

Points that are coplanar are on the same plane

Q, S, T and U are not coplanar, because they are not on the same plane.

Hence, (b) is false

(c) V lies on line ST

Point V is the point of intersection of line ST and plane A

This means that point V lies on line ST and plane A

Hence, (c) is true

(d) ST is perpendicular to plane A

Line ST intersects with plane A at point V at 90 degrees.

Perpendicular lines and planes meet at 90 degrees

Hence, (d) is true

It is most important to have a random sample in inferential statistics, particularly in making statistical inferences about a population based on the sample data.

Random sampling is a critical component of inferential statistics because it helps to ensure that the sample is representative of the population. When a sample is randomly selected, each member of the population has an equal chance of being included in the sample, which reduces the risk of bias in the results. Without a random sample, the results of statistical analyses may not be accurate or generalizable to the population, and the conclusions drawn from the data may be flawed or misleading.

Therefore, random sampling is crucial in making valid statistical inferences about a population.
