From equation 1 e=23-6f
sub 1 into 2. 2(23-6f)-f=7
46-12f-f=7
46-7-12f-f=0
39-11f=0
39=11f
then u divide both side by 11
therefore f=3.55
subtitude f in 1
6(3.55)+e=23
21.3+e=23
e=23-21.3
e=1.7

If 40% of a number is 80 what is 25% of that number?
olga2289 [7]

Answer:

25% of 200 is 50

Step-by-step explanation

40% of a number is 80

.40 * n = 80

Divide each side by .4

.40 n/.4 = 80/.4

n = 200

The number is 200

Now lets find 25 percent of that number

.25 * 200 = 50

The first quartile of a data set is 18, the median is 25, the third quartile is 28,
laila [671]
The outlier would be shown as a dot so the answer is B. 45
The interquartile range is 28 - 18 = 10
A simple rule is that points more than 1.5xIRQ above or below the medians is an outlier and is shown as a point.
28 + 1.5x10 = 43. 45 is above this value.
