When put in matrix form, the coefficients of
... 3x -2y = 7
... x + 4y = 2
look like
The determinant is 3×4 - 1×(-2) = 14.
Answer:
I) the value of X is 60
60=1×_
2×30
3×20
4×15
5×12
6×12
6×10 = 60
ii) 2 and 3 you also can put 5

Answer:
35
Step-by-step explanation:
x+8+243/2
x+251/2
x+251/2=4x+3
cross multiply
x+251=2(4x+3)
x+251=8x+6
x-8x=6-251
-7x=-245
x=-245/-7
x=35
Answer:
13 participants.
Step-by-step explanation:
Given that a researcher reports an F-ratio with df = 1, 24 for an independent-measures experiment.
i.e. degrees of treatment between groups =1
and within groups = 24
This implies that there are two groups.
For two groups to have same number of participants, since we get total of degrees of freedom =24+1 =25
Hence total items selected = 26
i.e. each group would have 13 entries
So each treatment had 13 participants.
The distributive property....u r basically multiplying the number outside of the parenthesis by everything inside the parenthesis...this gets rid of the parenthesis.
3(-4x + 8)...distribute the 3 thru the parenthesis
(3 * -4x) + (3 * 8) ...take that 3 and multiply it by every number in the parenthesis..to get rid of the parenthesis
-12x + 24 <===
4(x - 6y) =
(4 * x) - (4 * 6y) =
4x - 24y <===
6(5 - q) =
(6 * 5) - (6 * q) =
30 - 6q <===
1/2(c - 8) =
(1/2 * c) - (1/2 * 8) =
1/2c - 4 <===
-3(5 - b) =
(-3 * 5) - (-3 * b) =
-15 - (-3b) =
-15 + 3b <===
(d + 2)(-7)....re-arrange
-7(d + 2) =
(-7 * d) + (-7 * 2) =
-7d + (-14) =
-7d - 14 <===
