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
Option D is correct since both are complex conjugates.
Answer: ad = bc
Step-by-step explanation: A proportion is an equation which states that two ratios are equal. For example, is an example of a proportion.
In the given proportion, <em>a</em> and <em>d</em> are called <u>extremes</u> and <em>b</em> and <em>c</em> are called <u>means</u>.
The first property that I will be talking about states that <u><em>the product of the extremes equals the product of the means</em></u><u>.</u>
<u />
This idea is called the means-extremes property.
So if , we know that <em>a</em> times <em>d</em> equals <em>b</em> times <em>c</em> by the means-extremes property or <em>ad = bc</em>.
So the solution to the proportion is ad = bc.
The answer to that question is 7 . You have to add 7 to both sides
Answer:
B
Step-by-step explanation:
Point slope is in the form
(y - y1) = m(x - x1)
where x1 and y1 are the coordinate of any point on the line, and m is the slope
The others do not work
