Use the following scenario to find the t-calculated. You are a school psychologist interested in whether your 31 students' school attendance is significantly different from the
overall student population. Your 31 students missed an average of 14 days per semester (standard deviation of 3).
However, the overall student population missed an average of 33 days per semester. What is the t-calculated for this
scenario?
O 21.5
O 22.09
O-35.26
O 33.01

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius

: )

12

step-by-step explanation:

12 + 5 = 17

12x2=24

24-7=17
