Suppose in your sample of 25 trucks, you found a sample mean of 19.58 cubic feet, and a standard deviation of 2.3 cubic feet. What test statistic and P-value result from this sample mean?

Answer:

28x

Step-by-step explanation:

7×3x=21x+x×7=7x

21x+7x×28x

Answer:

44/15 converted into a mixed number   = 2(14/15)

Step-by-step explanation:

44/15 =     2.9333333...... = 2( 14/15)

so it is the number 2 and   (0.93333)

Lets see how is  the  decimal is in fraction

0.93333  is a mixed recurrent number  and in fraction is  14/15

14/15 = 0.93333.....

With recurring  mixed  decimal :

For the top part:

Take the non-repeating and the repeating(93) and subtract the non repeating(9)

93-9= 84

For the bottom part: for  every repeating decimal,you put a 9  And for every non repeating decimal,you put a zero

so one 9 and one zero (90)

84/90  = 14/15  = 0.93333....

Which could be the description of a cross section of a right cylinder that is neither parallel nor perpendicular to the base;

The options obtained from an online source (PSD) are;

Circle

Ellipse

Rectangle

Triangle

The cross section of a right cylinder that is parallel to the base is in the shape of a circle

The cross section of a right cylinder that is perpendicular to the base of the cylinder is in the shape of a rectangle

The cross section of a right cylinder that is neither parallel nor perpendicular to the base of the cylinder is in the shape of an ellipse which is a form of an oval shape.

Answer:

9 different car washes

Step-by-step explanation:

From the services that Jorge offers we can see that there are 3 options (wax, vacuum, and interior cleanings) on 3 different categories of vehicles (cars, trucks, and SUV). Therefore, in order to calculate the number of possible combinations or car washes that you can make, we need to multiply the number of options by the number of categories of vehicles. Like so...

3 * 3 = 9

Therefore, we can see that there are a total of 9 different car washes that you can make for the weekend.

Answer:

y  =  (3/4)*x - 14

Step-by-step explanation:

The slope-point general equation of the straight line is:

y  =  m*x  + b

In that equation,  m is the slope and b is the intercept with y-axis

The equation has two parameters to determine m and b. for a different pair of values we get just one unique straight line equation. To do that we need two conditions.

Here we have m = 3/4 and the point P ( 16 , -2), by substitution

y  =  (3/4)*x + b     and

- 2 = (3/4)*16 + b         - 2  = 3*4 +b            -2 = 12 +b    b  = -14

Then the final equation is:

y  =  (3/4)*x - 14

Answer:

2.2

Step-by-step explanation:

Given the data :

X = 5, 5, 5, 6, 9, 10, 10,10, 10, and 10

Mean of the data, xbar = 8

The mean absolute deviation, MAD is obtained thus :

Σ|x - xbar| / n

n = sample size

Σ|x - xbar| = (3 + 3 + 3 + 2 + 1 + 2 + 2 + 2 + 2 + 2)

Σ|x - xbar| / n = 22 / 10

MAD = 2.2

Akiko ate per hour:-

So

20min=1/3h

Total hot dogs

Answer:

2 hot dogs

Step-by-step explanation:

Total hot dogs she ate in 10 hours,

→ 60 hot dogs

Total hot dogs she ate in 1 hour,

→ 60/10

→ 6 hot dogs

The fraction of 20 minutes in a hour,

→ 20 minutes/1 hour

→ 20/60

→ 2/6 = [ 1/3 ]

Rate of hot dogs she ate in 20 minutes,

→ 6 × 1/3

→ 6/3

→ [ 2 hot dogs ]

So, Akiko ate 2 hot dogs in 20 minutes.

Answer:

19.64°

Step-by-step explanation:

The angle of elevation can be calculated as follows

Tan ©= 15/42

= 0.357

= tan-1 0.357

= 19.64°

Hence the angle of elevation is 19.64°

Answer:

Variability describes how far apart data points lie from each other and from the center of a distribution. Along with measures of central tendency, measures of variability give you descriptive statistics that summarize your data. Variability is also referred to as spread, scatter or dispersion.
