Answer:

Mean= 13.38

Median= 15

Step-by-step explanation:

The mean can be calculated by getting the sun of the 8 scores and then dividing it by the number of students

Mean= 7 + 18 + 18 + 15 + 17 + 10 + 15 + 7/8

= 107/8

= 13.38

The median can be calculated by first rearranging the numbers from the lowest to the highest and then calculating the average of the two middle numbers

7 , 7, 10, 15, 15, 17, 18, 18

Median = 15+15/2

= 30/2

= 15

Hence the mean is 13.38 and the median is 15

Maths equation : solve (2 - x)² < 4/25​
ipn [44]

Answer:

8/5 < x < 12/5

Step-by-step explanation:

(2 - x)² < 4/25​

2 - x < ±2/5

2 - x < 2/5

-x < -8/5

x > 8/5

2 - x > -2/5

-x > -12/5

x < 12/5

Therefore, your answer is 8/5 < x < 12/5

Choose the correct slope of the line that passes through the points (1, −3) and (3, −5).
Flura [38]
Slope of a line passing though point (x1,y1) nd (x2,y2) is
(y2-y1)/(x2-x1)

we have
(1,-3) and (3,-5)
x1=1
y1=-3
x2=3
y2=-5

slope=(-5-(-3))/(3-1)=(-5+3)/(2)=-2/2=-1

slope=-1

Lynna [10]

Answer:

B. 12.5

Step-by-step explanation:

We have the lowe confidence interval = 185

The upper confidence interval = 210

Mean of X = (lower confidence + upper confidence interval)/2

Mean of X = 185 + 210/2

= 197.5

The margin of error = the upper confidence interval - mean of X

= 210-197.5

= 12.5
