Answer: 0.345
Step-by-step explanation:
Given : The incomes of families in Newport Harbor are normally distributed with Mean : 
and Standard deviation : 
Samples size : n=4
Let x be the random variable that represents the incomes of families in Newport Harbor.
The z-statistic :-
For x= $800,000
By using the standard normal distribution table , we have
The probability that the average income of these 4 families exceeds $800,000 :-
Hence, the probability that the average income of these 4 families exceeds $800,000 =0.345
Answer:
BC = 30
Step-by-step explanation:
AC = 48, AC = AB + BC, AB = 2x + 2 , BC = 3x + 6 => AC = 2x + 2 + 3x + 6 =>
=> AC = 5x + 8 , AC = 48 => 5x = 40 => x = 8 , BC = 3x + 6 => BC = 24 + 6 = 30
Answer:
Acute angle

Answer:
21/128
Step-by-step explanation:
Area = L * w
L = 7/8
w = 3/16
Area = 7/8 * 3/16
Numerator of the answer = numerator * numerator = 3 * 7 =21
denominator of the answer = denominator * denominator = 8 * 16 = 128
Answer is 21 / 128. This fraction cannot be reduced.
The answer is A
Answer:
20 apples every 1 tree
Step-by-step explanation:
first, we need to find the constant!!
(constant means what you use to multiply in every equation)
so we do 100 apples divided by 5 trees!
the answer will be 20 apples and we know that we need to find how much PER ONE TREE
so, 1 tree = 20 apples !
