Answer:
y-1=7(x-0)
Step-by-step explanation:
The line perpendicular to y=-1/7+1 is y=7+1 because you find the reciprocal of the slope.
Then find one point on the line since the equation has a y intercept just use (0,1) and put that into point slope
Answer:
A= -40
B= 16
C= 40
D= 50
Step-by-step explanation:
Sentences? Do you mean like equations
The probability of being in the smaller triangle is the area of the smaller triangle divided by the area of the larger triangle...
P(inside smaller triangle)=(2*2/2)/(6*5/2)
P(inside smaller triangle)=2/15
Suppose the student guesses the answers, we shall consider this a binomial probability problem of success. This implies that getting a question right is p=1/5.
The number of questions is n=20 questions.
The mean of binomial distribution is
mean=n*p= 20*1/5=4
b] The standard deviation of a binomial distribution is given by:
σ=√(n*p*(1-p))
=√(20*0.2*0.8)
=1.79~1.8
Answer:
μ=4 ; σ=1.8
