What is the slope of the line shown below?

B.  

Step-by-step explanation:

The formula to calculate the slope of a line passing through (a,b) and (c,d) is given by :-

From the graph it can be seen that the line is passing from (-3,-1) and (5,1), then the slope of the given line will be :-

Hence, the slope of the given line is graph =

hello,

b) 62.47% of the students are between 14 and 18 years old.

step-by-step explanation:

mean = 15 and standard deviation = 2

student between 14 to 18

formula used z-score

for age 14 , z score

using z-table , p(z> -0.5)=0.3085

for age 18 , z score

using z-table , p(z< 1.5)=0.9332

p(-0.5< z< 1.5)=0.9332-0.3085 = 0.6247

thus, 62.47% of the students are between 14 and 18 years old.
