Answer:
(A) It is less than the contribution predicted by the regression line.
Step-by-step explanation:
The residual is the subtraction of the observed value by the predicted value.
So, if James has a negative residual, it means that his contribution is less than what was expected by the regression line.
The correct answer is:
(A) It is less than the contribution predicted by the regression line.
Answer:
a) 0.216
b) 0.1587
c) 0.369
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 12.2 grams
Standard Deviation, σ = 2.8 grams
We are given that the distribution of weights of impurities per bag is a bell shaped distribution that is a normal distribution.
Formula:
a) P(contains less than 10 grams of impurities)
P(x < 10)
Calculation the value from standard normal z table, we have,

b) P(contains more than 15 grams of impurities)
P(x > 15)
Calculation the value from standard normal z table, we have,

c) P(contains between 12 and 15 grams of impurities)

d) The mean divide the data in exactly two parts. Since 15 is farther away from the mean as compared to 10, the probability obtained in part (b) is smaller as compared to probability obtained in part (a).
Answer:
3(x-3)/4-1/2=2/3
The least common denominator will be the least common multiple of 4,2,3 which is the product of the highest occurring primes of the numbers prime factorization...
Step-by-step explanation:
4=2*2, 2=2, 3=3, so the least common denominator is 2*2*3=12
The y - coordinate of D after a translation is 1
Explanation:
The point D after a translation is given by 
The y - coordinate of the point D is 5.
Now, we shall determine the value of the y - coordinate of D after the translation 
Let us consider the y - coordinate of D' and D
Thus, we have,

Subtracting both sides by 4, we get,

Thus, the y - coordinate of D after a translation is 1
