Answer:
x = 5.5
Step-by-step explanation:
Given 2 secants intersecting the circle from a point outside the circle then
The product of the external part and the entire part of one secant is equal to the product of the external part and the entire part of the other secant, that is
x(x + 14) = 6(6 + 12)
x² + 14x = 6 × 18 = 108 ( subtract 108 from both sides )
x² + 14x - 108 = 0 ← in standard form
with a = 1, b = 14 and c = - 108
Using the quadratic formula to solve for x
x = ( - b ± ) / 2a
= ( - 14 ± ) / 2
= ( - 14 ± ) / 2
= ( - 14 ± ) / 2
x = or x =
x = - 19.5 or x = 5.5 ( to 1 dec. place )
However x > 0 ⇒ x = 5.5
three hundred fourteen thousand and two hundred seven.
Answer:
The expected number of interviews is 3.25.
Step-by-step explanation:
For each person applying for a profissional position, there are only two possible outcomes. Either they land an interview, or they do not. The probability of a person landing an interview is independent of any other person. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
Probability of exactly x sucesses on n repeated trials, with p probability.
The expected value of the binomial distribution is:
In this problem, we have that:
So
The expected number of interviews is 3.25.
Answer:
1. 395.96 2. addition 3. I picked it because each night it is 98.99 so if you were there for 4 days you would do 98.99 +98.99 +98.99 +98.99. Which equals 395.96.
Step-by-step explanation:
Step-by-step explanation:
We are given that
Priya uses flour to make 3 loaves of bread= 7 1/2 = 15/2 cups
Andre uses b loaves of bread using flour=f cups
We have to find the relationship between b and f.
When both recipes are same then ratio of flour to the loaves of bread remains same in both recipes.
To find the relationship between b and f we will find the ratio of flour to the loaves of bread in Priya's recipe.
Therefore, ratio of flour to the loaves of bread in Andre's recipe
This is required relationship between b and f.
