Answer: 0.9591
Step-by-step explanation:
Given : The probability that a person likes ice cream is p=0.80.
Sample size : n= 1000
Using the normal approximation to the binomial ,
Let x be the random variable that represents the number of people like ice cream.
Now, the probability that 822 or fewer people selected like ice cream will be :-
[∵ ]
[using p-value table for z]
Hence, the required probability = 0.9591
If Rachel's total budget was n, then:
.45n=$76.5 divide both sides by .45
n=$76.5/.45
n=$170.00 Rachel's total budget.

Answer:
$15.95
Step-by-step explanation:
M= S - N
S= N + M
S = $6.54 + $9.41
The nonagon with the sum of 5 angles of 800 and three of the remaining angles equal to the other angle has the equal angle as 120 degrees
<h3 /><h3>What is a nonagon?</h3>
A nonagon is a polygon with 9 sides and interior angles.
Therefore,
sum of interior angles of a nonagon = 1260
let
x = size of the equal angles
800 + 3x + 100 = 1260
900 + 3x = 1260
3x = 1260 - 900
3x = 360
divide both sides by 3
3x / 3 = 360 / 3
Therefore,
x = 120
