Answer:
We are given the t distribution with 16 degrees of freedom.
We have to find the area a. to the right of 2.120
Answer: We can use excel to find the area to the right of 2.120. The excel function is:
=TDIST(2.120,16,1) = 0.025
Therefore, the area to the right of 2.120 is 0.025
b. to the left of 1.337.
Answer: We can use excel to find the area to the left of 1.337. The excel function is:
=1 - TDIST(1.337,16,1) = 0.900
Therefore, the area to the left of 1.337 is 0.900
Answer:
Step-by-step explanation:
The difference is 2 , just -4 + 6 .
Plus x on bot sides. then divide both sides by 2 to get y by itself.
Answer:
KL = 23
KM = 29
Step-by-step explanation:
By applying cosine rule in the given triangle KLM,
cos(∠M) = 
cos(52°) = 
cos(52°) = 
KM = 
KM = 29.24
KM ≈ 29
By applying sine rule,
sin(52°) = 
sin(52°) = 
KL = 29.24[sin(52°)]
= 23.03
≈ 23
KL = 23
