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:
<h2>A multiple of 10 cannot have anything but a zero as its final digit</h2>
Step-by-step explanation:
In other words, 10 times anything is 20, 30, 40, 50 and so on, but never 35.
<h3>Examples:</h3>
10 x 1 = 10
10 x 2 = 20
10 x 3 = 30
10 x 4 = 40...
10 x 123 = 1,230
A simple rule to help you is that a number multiplied by 10 is always that number with a zero added on the end. Look above to see what I'm talking about.

OK, If I understand your question correctly your vertex is at E and the arc is defined by ED or DE.
<span>In this case the measure of angle DEF is just 1/2 of the arc length in degrees or 88 degrees.</span>
Find amount used:
Amount in the card = $20
Amount left = $13.28
Amount used = $20 - $13.28 = $6.72
Find duration of the call:
24 cents = 1 min
672 cents = 1/24 x 672 = 28 mins
Answer: The call was 28 minutes long.
