The two rates that can be used to represent this relationship are:
A ratio is a comparison between two numbers that can be separated with (:) sign or can be represented as a fraction. This comparison deals with the same units.
However,
From the parameters given:
For every 2 cups of barbecue sauce, 4 pounds of pulled pork is used.
Therefore, we can conclude that the two rates that can be used to represent this relationship are:

a. Slope = -0.35
y-intercept = -10.9
b. Slope = -0.35
y-intercept = 10.9
c. Slope = 0.35
y-intercept = -10.9
d. Slope = 0.35
y-intercept = 10.9
Slope & Intercept are : D) 0.35 , 10.9
Regression is the relationship between explanatory (independent) & dependent variable, which are x & y respectively.
The regression equation y = a + bx + c has intercept & slope a & b respectively , formula for finding them are as follows :
b = r ( σy / σ x )
0.223 ( 3.03 / 1.92 )
= 0.223 (1.578125)
= 0.3519
a = Y' - bX'
a = 13.8 - 0.3519 ( 8.2 )
= 13.8 - 2.8558
= 10.91
Regression Equation : y = 10.9 + 0.35x

Answer:
d. Slope = 0.35
y-intercept = 10.9
Step-by-step explanation:
The computation is shown below:
Data given in the question
Mean = 8.2
The standard deviation of x = = 1.92
Mean = 13.8
The standard deviation of y = = 3.03
The correlation = r = 0.223
Based on the above information,
As we know that
The slope is
= 0.3519
Now the y-intercept is
= 13.8 - (0.351922) 8.2
= 13.8 - 2.88579
= 10.91
Answer:
Step-by-step explanation:
Assuming the order in which he answers the questions matter the answer is the number of permutations of 8 in 10.
This is 10! / (10-8)!
= 1,814.400.
If the order does not matter then the answer is the number of combinations of 8 from 10:
This is 10!/8!*2!
= 45.
Answer:
1.8 times the cost of labor.
Step-by-step explanation:
At the beginning of the year, the rate for overhead was estimated to be ...
(overhead $)/(direct labor $) = $396/$220 = 1.8
The overhead rate is 1.8 times the labor cost.
Answer:
False
Step-by-step explanation:
Correlation is not causation.
It may mean that eating popsicles and buying sunglasses have a common cause: sunny days.
Answer:
3x (x² + x + 1)
You could write any trinomial like this
B) 0.3187
C) 0.2451
D) 0.754
The probability that there will be fewer than 20 no-shows will be "0.2451".
According to the question,
= 1 - 0.15
= 0.85
The Mean will be:
→
By substituting the values, we get
Standard deviation will be;
→
By using the normal distribution to approximate the binomial distribution, we get
→
Thus the above answer i.e., option C) is correct.
