Answer:

9.54 feet

Step-by-step explanation:

Using Pythagoras rule :

Length of ramp = 10 feets = hypotenus

Hypotenus² = opposite² - adjacent²

d² = 10² - 3²

d² = 100 - 9

d² = 91

d = √91

d = 9.5393920

d = 9.54 feets

Answer:

0.97725

Step-by-step explanation:

Given :

Population mean, μ = 4.2

Population standard deviation, σ = 1.8

Sample size, n = 36

Obtain the Zscore of x = 4.8

Zscore = (x - μ) ÷ (σ / √n)

Zscore = (4.8 - 4.2) ÷ (1.8 / √36)

Zscore = 0.6 ÷ 0.3

Z = 2

Hence,

P(Z ≤ 2)

Using the Z probability calculator :

P(Z ≤ 2) = 0.97725

Answer:

Box volume ≈ 5,434 ft³

Step-by-step explanation:

Given: Railroad boxcars are 52 feet long, 9.5 feet wide, and 11 feet

To find: The volume, in cubic feet, of common railroad boxcars

Solution: To find the volume of a box, simply multiply the length, width, and height.

                                           52 × 9.5 × 11 = 5434

Therefore, the volume, in cubic feet, of common railroad boxcars is 5,434 ft³

For dimensions that are relatively small whole numbers, calculating volume by hand is easy.

Answer:

a. Nominal and qualitative.

b. Ratio and quantitative.

c. Interval and quantitative.

d. Interval and quantitative.

Step-by-step explanation:

A level of measurement can be defined as a classification which is used to illustrate the attributes of the values assigned to variables. There are four (4) basic levels of measurement for a variable and these are;

1. Interval: data can be arranged in an ordering scheme and subtracting its differences is meaningful. Examples are year, temperature, time etc.

2. Ratio: data can be arranged in an ordering scheme and subtracting its differences is meaningful with respect to the value of true zero. Examples are height, price, weight, distance etc.

3. Ordinal: data can be arranged in an ordering scheme but subtracting its differences is meaningless or impossible. Examples are happy, sad etc.

4. Nominal: is characterized by data that are non-numerical, comprises of categories, labels or names and can't be arranged in an ordering scheme.

In this scenario, the level of measurement and data type are listed below;

a. End-of-year stock classification (high yield, medium yield, or low yield): the level of measurement is nominal because they are categorized. Also, the type of data is qualitative because it describes the quality of the stock and it's non-numerical in nature.

b. Length (in feet) of a roll of plastic wrap advertised to be 30 feet long: the level of measurement is a ratio because they can be arranged in order. Also, it's a quantitative data because it is numerical in nature.

c. Temperature (in degrees Celsius): the level of measurement is an interval because they can be arranged in order and the difference in value is meaningful. Also, the type of data is quantitative because it is numerical in nature.

d. Duration (in minutes) of a call to a customer support line: the level of measurement is an interval because they can be arranged in order and the difference in value is meaningful. Also, the type of data is quantitative because it is numerical in nature.

Answer:

a. AA Similarity Postulate

Step-by-step explanation:

the AA Similarity Postulate says that if two angles in one triangle are congruent to two angles in another triangle, then the two triangles are similar.

AB and ED are parallel, so

Answer:

4π mi²

Step-by-step explanation:

s = (∅/360) * πr²

s = (135/360) * π(4²)

s = (135/360)(16) * π

s = 4π mi²

Answer:

c. Yes because the cut-off is more than the sample mean

Step-by-step explanation:

The null and alternate hypotheses are

H0 : u= 3.5 ounces  vs Ha: u > 3.5 ounces

The mean and standard deviation of the sample are calculated to be 3.76 and 0.24

The test statistics is

t= x`- u/s√n

= 3.76-3.5/0.24/√10

= 0.26/0.07589

=3.426

The critical region for z test is  z > ± 2.33

The critical region for t test is   t > ± 2.82 for 9 d.f

For both the tests( z and t)   the test statistic =3.426 lies  in the critical region.

Hence we reject H0 and accept the hypothesis that  the new design is better than the old one at a level of significance of 1%.

cut-off = mean + 3 times the standard deviation

          =  3.76 + 3* 0.24

 cut-off     =4.48

Yes, the cut off is more than the sample mean.

So choice c is the best option.

The sum of all values divided by the total number of values determines the mean (also known as the arithmetic mean, which differs from the geometric mean) of a dataset. The term "average" is frequently used to describe this measure of central tendency.

Ranks in a dancing competition: This is an illustration of ordinal measurement since the values can be ranked or ordered, but the differences between the values are meaningless.

Basketball player heights: Although there isn't a genuine zero point, the values have significant variances between them, making this an example of an interval measurement.

Monthly electric bills are an example of a ratio measurement because there are real zero points and significant variances between the values.

Calendar day count: Because the values are categorical and cannot be ranked or sorted, this is an example of a nominal measurement.

Score on an aptitude test: This is an instance of an interval measurement because there are actual disparities between the results, but no actual zero point.

Answer:

The total length of fencing that Bethany will need is 21.5 feet.

Step-by-step explanation:

Since Bethany is making a rectangular fenced- in area for her rabbit in her yard, and the area measures 4 3/4 feet wide by 2 yards long, to determine what's the total length of fencing that Bethany will need in feet the following calculation must be performed:

1 yard = 3 feet

2 yards = 6 feet

3/4 = 0.75

4.75 x 2 + 6 x 2 = X

9.5 + 12 = X

21.5 = X

Therefore, the total length of fencing that Bethany will need is 21.5 feet.

Answer:

Step-by-step explanation:

Number 5 is L because you have 18 coins but you only want to find the probability of the pennies. So take 3/18 and simplify to 1/6 by dividing both the numerator and the denominator by 3.

Number 6 can be (-6x - 3), just use the distributive property on the original expression.

Answer:

5. I.

6. -6x - 3

Step-by-step explanation:

For number five you add up all the coins, which equals 18. Secondly, you see how many pennies there are. There are 3 so the answer is 3/18. Then you simpy into 1/6.

For number six, you want to multiply 3 by -2x and then multiply 3 by -1. You will get the answer -6x -3. If you see a number outside the parenthesis then multiply by the number inside of it.

Answer:

The inverse of the function is [tex]f^{-1}(x) = \sqrt[3]{\frac{x-16}{8}}[/tex]

Step-by-step explanation:

Inverse of a function:

Suppose we have a function y = g(x). To find the inverse, we exchange the values of x and y, and then isolate y.

In this question:

[tex]y = \frac{x^3}{8} + 16[/tex]

Exchanging x and y:

[tex]x = \frac{y^3}{8} + 16[/tex]

[tex]\frac{y^3}{8} = x - 16[/tex]

[tex]y^3 = \frac{x-16}{8}[/tex]

[tex]y = \sqrt[3]{\frac{x-16}{8}}[/tex]

The inverse of the function is [tex]f^{-1}(x) = \sqrt[3]{\frac{x-16}{8}}[/tex]

Answer:

30 dimes

Step-by-step explanation:
