Answer: 21?
Step-by-step explanation: if the ratio is 7:5 and its now x:15 and 15 divided by 5 is three so you have to multiply 7 by three to.
Answer:
62.9
Step-by-step explanation:
Answer:
The provided statement is True.
Step-by-step explanation:
Holding a variable constant implies that there are no kind of relationship between the variables and the treatments.
Holding a participant variable constant has the double advantage:
(1) preventing the variable from becoming a confounding variable
(2) reducing variance within groups.
A confounding variable effects both the dependent and the independent variable remarking a relationship between the two.
Variation within group implies the difference caused by the individual values of each group.
Thus, the provided statement is True.
Answer:
x = 15 5/6
Step-by-step explanation:
-4 1/4x-7 6/8x=-190
get a common denominator 8
-4 1/4*2/2 x - 7 6/8 x = -190
-4 2/8 x - 7 6/8 x = -190
combine like terms
-11 8/8 x = -190
-12x = -190
divide by -12
-12x/-12 = -190/-12
x = 190/12
divide top and bottom by 2
x = 95/6
change to an improper fraction
6 goes into 95 15 times with 5 left over
x = 15 5/6
Step-by-step explanation:
Since, Point E is the midpoint of DF
Therefore,
DE = EF
10x = 4x + 12
10x - 4x = 12
6x = 12
x = 12/6
x = 2
EF = 4x + 12 = 4*2+12 = 8 * 12 = 20
EF = 20
AB = BC
6x + 2 = 9x - 10
10 + 2 = 9x - 6x
12 = 3x
12/3 = x
x = 4
BC = 9x - 10 = 9*4 - 10 = 36 - 10 = 26
