<h3>answer</h3>
we assume the height of the triangle is x,
so the base length will be x+4
the triangle area will be area = 1/2 ( base * height)
48 = 1/2 (x + 4) x
96 = x2 + 4x
96 + 4 = x2 + 4x + 4
100 = (x + 2)2
10 = x + 2 (for the square 100, we ignore the -10, minus is meaningless in length )
x = 8
x + 4 = 8 + 4 = 12
so the height for the triangle is 8 unit, base is 12 unit,

Answer:
Parallel
Step-by-step explanation:
QR and ST both parallel to y axis.
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
Answer:
1360
Step-by-step explanation:
1 bag cost 85 so 16 bag cost = 85×16=1,360
