The first blank is leaning to the left, the second blank is in the middle, and the third blank has 9 alternatives that are legitimate.

We've done that.

Data from Gretchen can be characterized as having a __ shape. As a result, the __ will serve as this data set's best measure of center.

For the best measure of center, the real value is .

The word in the blank must be identified using the provided diagram.

What is left that is skewed?

A left-skewing distribution has a long left tail. Left-skewed distributions are another name for negatively skewed distributions. This is caused by the number line's huge negative tail. Furthermore, the peak is offset from the mean. A right-skewed distribution has a long right tail.

Consequently, the appropriate choices are,

the third blank is 9, the second blank is middle, and the first blank is tilted to the left.

(a) Acceleration

We know the initial velocity, u = 4.00 m/s, and the time, t = 9.23 s, taken by the sprinter to run the relay race. We can use these values to find the acceleration, a, using the formula:v = u + at

Rearranging the formula gives us:a = (v - u)/t

where v = final velocity

We are given that the runner runs with constant acceleration, so we can assume that the acceleration is uniform, i.e., constant throughout the race.

Therefore, we can find the average acceleration, a, using the formula:

a = Δv/Δt

where

Δv = change in velocity = v - u = final velocity - initial velocity

Δt = change in time = t - 0 (since we are assuming the sprinter started from rest)

Substituting the given values gives:

a = Δv/Δt = (v - u)/(t - 0) = (v - 4.00)/9.23a = 1.49 m/s² (correct to 3 significant figures)

(b) Final speed

We can find the final speed, v, using the formula:v = u + at

Substituting the values for u and a calculated in part (a) gives:

v = 4.00 + 1.49(9.23) = 17.3 m/s (correct to 3 significant figures)Assessing the answer

We have answered the question and provided the correct units (m/s² and m/s), signs, and significant digits.

Our answer is reasonable because it is consistent with the information given in the question and the values are within the expected range for a sprinter of Andre De Grasse's caliber.

Answer:

Step-by-step explanation:

Unfortunately, I cannot answer this question without additional information about the distances traveled and the time taken by Reiko to travel from point A to point B and back to point A.

The speed at which Reiko traveled is calculated as distance divided by time. Therefore, we need to know both the distance and time for each leg of the journey to determine the speed.

Without this information, it is not possible to determine whether Reiko traveled from A to B at a speed greater than 40 miles per hour.

Steve can select three rock songs, five alternative songs, and six rap songs in 11,250 number of ways.

1. To select three rock songs from a list of five, use the formula for combinations: nCr = 5Cr = 5!/ (3!*2!) = 10

2. To select five alternative songs from a list of six, use the formula for combinations: nCr = 6Cr = 6!/ (5!*1!) = 6

3. To select six rap songs from a list of nine, use the formula for combinations: nCr = 9Cr = 9!/ (6!*3!) = 84

4. To find the total number of selections, multiply the individual combinations: 10 x 6 x 84 = 11,250

Answer:

The total number of burritos consumed is 68 and an equation to determine the total number of burritos consumed is \(\frac{1}{2}x+16=\frac{3}{4}x-1\)

Step-by-step explanation:

Let x be the total number of burritos consumed

We are given that On Tuesday, Delainey ate 16 more than 1/2 the total number of burritos consumed

So, Number of burritos ate by Delainey on Tuesday=\(\frac{1}{2}x+16\)

We are also given that  Louie ate 1 less than 3/4 of the total number of burritos consumed.

So, Number of burritos ate by Louie on Wednesday =\(\frac{3}{4}x-1\)

We are given that The number of burritos Delainy ate on Tuesday is the same as the number of burritos Louie ate on Wednesday.

So, \(\frac{1}{2}x+16=\frac{3}{4}x-1\\1+16=\frac{3}{4}x-\frac{1}{2}x\\17=\frac{x}{4}\\68=x\)

Hence  the total number of burritos consumed is 68 and an equation to determine the total number of burritos consumed is \(\frac{1}{2}x+16=\frac{3}{4}x-1\)

Based on the time that you departed Seattle and the layovers in Dallas and Portland, you will arrive in Seattle at 6:45 am.

If you leave Seattle at 9:10 pm, you will arrive in Atlanta at 10:25 am .

If the leg from Dallas back to Atlanta is 2/3 of an hour longer then you will arrive at 11:05 am.

The hours you will spend going from Atlanta to Seattle including layover times is:

= 2.75 + 1.5 + 3.5 + 1.75 + 0.75

= 10 hours 15 minutes

The time you will arrive in Seattle is:

= 11:30 pm + 10 hours 15 minutes - 3 hour time difference

= 6:45 am

Your total flight time and layover time is 10 hours 15 minutes. You will therefore arrive in Atlanta at:

= 9:10 pm + 10 hours 15 minutes + 3 hour time difference

= 10:25 am

If the leg back to Atlanta took an additional 2/3 of an hour then you would arrive at:

Using the median concept, the largest sample observation could be decreased until it is equal to the median without affecting the value of the median.

The median of the data-set separates the bottom half from the upper half, that is, it is the 50th percentile.

From it, we get that the median is the middle value and is not influenced by outliers, hence the largest sample observation could be decreased until it is equal to the median without affecting the value of the median.

If it is decreased by to a value lower than the median, the middle value would change than the median would be affected.

The foot of the cable is 95 feet away from the base of the tree.

Trigonometric functions are mathematical functions that relate the angles of a right triangle to the ratios of the sides of the triangle.

We have,

The angle between the ground and the cable is given as 61º.

In a right triangle, the side opposite the angle (in this case, the height of the tree) is related to the hypotenuse (the length of the cable) and the adjacent side (the distance from the foot of the cable to the base of the tree) by the trigonometric function cosine.

Cosine(angle) = adjacent/hypotenuse

Cos(61º) = adjacent/200 ft

adjacent = Cos(61º)x200 ft

adjacent ≈ 0.475 x 200 ft

adjacent ≈ 95 ft

Therefore, the foot of the cable is 95 feet away from the base of the tree.

The one mean Z test can be used for small samples of size less than 15 when the population standard deviation is known.

The one-mean z-test is a hypothesis test that is used to test a hypothesis about the mean of a population when the population standard deviation is known, and the sample size is large (typically greater than 30).

When the sample size is small (less than 15), the one-mean z-test is not appropriate because the assumptions of the test may not be met.

When the sample size is small, we typically use a t-test instead of a z-test to test a hypothesis about the population mean.

Specifically, we use a one-sample t-test when the population standard deviation is unknown, and the sample size is small (typically less than 30).

The one-sample t-test uses a t-distribution to calculate the p-value and test the null hypothesis about the population mean.

It is important to note that the sample size of 15 is not a hard and fast rule for when to switch from the z-test to the t-test.

The decision of which test to use depends on the specific context and the assumptions of the test.

In general, if the population standard deviation is unknown and the sample size is small (less than 30), then we use the t-test. If the population standard deviation is known and the sample size is large (greater than 30), then we use the z-test.

a) When Lily's age is 20, and Raphael's age is divided by 3 then the expression of Lily's age in terms of h is h < 10.

b) Ethan's age is half of Raphael's age therefore, Ethan's age is half Raphael's age.

a) If Raphael is twice as old as his sister Lily, we can represent their ages as 2h and h, respectively, where h is Lily's age. The sum of their ages is less than 30, so we can write the equation:

2h + h < 30

Combining like terms, we get:

3h < 30

Dividing both sides by 3, we get:

h < 10

This is an expression of Lily's age in terms of h.

b) If Ethan's age is 16, and Raphael's age is twice Ethan's age, we can represent Raphael's age as 2 × 16 = 32.

Ethan's age is 16, which is half of Raphael's age of 32. Therefore, Ethan's age is half of Raphael's age.

Step-by-step explanation:

The area of the dinner plate is 1017.36 cm^2 if the circumference of the given dinner plate is 113.04 cm.  

The circumference of the dinner plate is

= 113.04 cm

The circumference of a circular region is

= 2πr

Therefore, to find the r (radius) of the dinner plate,

113.04 = 2πr

To find the radius of the dinner plate,

r (radius) = 113/(2π)

r = 113/(2× 3.14)

r = 18 cm

The area of a circular region is
