Problem 1 a jar contains blue, red and green balls. the null-hypothesis h0 is that there is 25% percent of red balls. (1) a samp

le of 36 ball have been randomly pull out of jar. it contained 16 red balls. what is the probability of that happening? do you still believe that jar contains 25% red balls? answer:_____________________________________________________ (2) we create a statistic which we will use to test the h0 . the statistic is simply a number of red balls in the sample of 36 balls. we make a decision that we will reject the null-hypothesis if sample contains more than 15 red balls. what is the probability of that happening assuming that null-hypothesis is true?

(1) the probability of that happening is .4444.. so on. the jar isnt 25% red balls because 25% of 36 is only 9 and he pulled out 16 red balls.

What is the area of the triangle? no links just the answer plz.
nikitadnepr [17]

Answer:

A = 25

Step-by-step explanation:

Base = |-2-(-7)| = |-2+7| = 5

equation of the line that includes the base

x = 6 (because it is parallel to y axis)

the height passes to the point (-4,-4) and must be perpendicular to the base

the equation of the line of the base hasn’t the slope expressed, so the line of the height has a slope equal to 0

so the equation of the line is y= -4

the point (6,-4) is where the two lines intercept and it is the point where the height hit  the base

height = |-4-6| = 10

A = (base x height)/2 = (5x10)/2 = 25
