Answer:
Two of these statements are true.
The function equals x^2 over the interval −∞ < x ≤ 0.
The function equals √x over the interval 0 ≤ x < ∞.
Step-by-step explanation:
If we look at the parent function of 
we see that function looks like a U shaped graph and in your graph we see it is the same as your graph from the interval (-∞,0).
If we look at the parent function of 
we see that the
function looks like your graph from the interval (0,∞).
Suggestion:
I suggest memorizing every graph of parent functions that is introduced to you in math. This can help you visually with many problems in mathematics, and help you conceptualize material better. I also suggest looking up the definition of every word that may be unfamiliar to you like "interval" and "parent function". This will help you understand more advanced math notations and vocabulary in the future.
Well, you need to draw a square and put 1.1 and 2.4 on each side then multiply to get your area. Of the square.
Answer:
a) P(X=41)= 0.0086 = 0.86%
b) P(36≤X≤38)== 0.1215 = 12.15%
c) would be unusual that fewer that 20 murders were cleared because P(X≤20) = 0.000081 =0.0081%
Step-by-step explanation:
if the random variable X= number of cleared murders , then X follows a binomial distribution:
P(X=x)= n!/[(n-x)!*x!]*p^x*(1-p)^(n-x)
where P(X=x)= probability of x cleared murders, n= number of murders selected=50 , p= probability for a murder to be cleared (67%)
therefore
a) P(X=41)=50!/[(50-41)!*41!]*0.67^41*0.33^(50-41)= 0.0086
b) P(36≤X≤38)= P(X≤38) - P(X≤36) = 0.9371- 0.8156 = 0.1215
c) P(X≤20) = 0.000081
therefore would be unusual that fewer that 20 murders were cleared
To find the correct option we need to calculate each of the given options.
Option (1):
Option (2):
Option (3):
option (4)
So, the correct answer is option (2)
Answer:
The square root will be about 4 because the formula for square root is √(x^2) = x
