Answer:
As in explanation.
Step-by-step explanation:
A) SSE means "Error Sum of Squares". The source of it is the sum of squared deviations within groups.
B) SSTR means "Treatment Sum of Squares". It's source is the weighted sum of squared deviations of group means from grand mean. It's the sum of squares between groups.
C) SST means "Total Sum of Squares''. It's source is total sum of squared deviations from the grand mean. It is a sum of SSE and SSTR.
Answer:
(-1 , 7)
Step-by-step explanation:
Read the symbol ∩ as the word "AND"
x-2 < 5 AND x+7 > 6
x< 5+2 AND x > 6-7
x < 7 AND x > -1
All the numbers greater than -1 AND less than 7
Interval (-1 , 7)
Answer:
interest earned= 1436.143
the future value of an annuity= 2836.143
Step-by-step explanation:
Given Data:
Interest rate= 4%
time,t = 18 years
Annual payment, P= 1400
At the end of 18 years, final investment A= ?
As per the interest formula for interest
A= P(1+r)t
Putting the values in above equation
= 1400(1+0.04)^18
= 2836.143
Interest earned = A-P
= 2836.143-1400
= 1436.143 !
Answer:
Please check the explanation.
Step-by-step explanation:
We know that when y varies directly with x, we get the equation
y ∝ x
y = kx
k = y/x
where 'k' is called the 'constant of direct variation'.
We are given that x = -2 and y = -2
Thus,
The equation is:
y = kx
substituting x = -2 and y = -2
-2 = k(-2)
-2 = -2k
We can further simplify the equation to determine the value of 'k'
so
dividing the equation by -2
-2/-2 = -2k/-2
1 = k
Therefore, the value of k = 1
Thus, the equation becomes
y = kx
substituting k = 1 in the equation
y = (1)x
y = x
Therefore, an equation that relates x and y is:
y = x
