Answer:
Probability of getting at least 9 out of 18 correctly is 0.0043
Step-by-step explanation:
We have
n = 18
p = 1/5 for correct answer
q = 4/5 for wrong answer
P( 9 
X 18) = 1 - P(0 X 8)
= 1 - 0.9957
=0.0043
Answer:
<u>Lower Upper Frequency</u>
1 6 2
7 12 4
13 18 7
19 24 1
25 30 4
Step-by-step explanation:
We sort the given data to get: 1,4,8,8,9,10,13,14,15,15,15,16,18,24,25,25,27,29
The range is 29-1=28
Class width=28/5=5.6
We round up to get 6
The lowest value is 1. Our lower class limits are:
1
7
13
19
25
The upper class limits are:
6
12
18
24
30
Now our frequency table is:
<u>Amount | Frequency</u>
1-6 2
7-12 4
13-18 7
19-24 1
25-30 4
Answer:
f(x)^-1(x) =sqrt(x+5) -6
Step-by-step explanation:
f(x) = (x + 6)^2 - 5
y = (x + 6)^2 - 5
Exchange x and y and solve for y
x = (y + 6)^2 - 5
Add 5 to each side
x+5 = (y + 6)^2 - 5+5
x+5 = (y + 6)^2
Take the square root of each side
sqrt(x+5 )= sqrt( (y + 6)^2 )
sqrt(x+5 )=(y + 6)
Subtract 6 from each side
sqrt(x+5 ) -6=y + 6-6
sqrt(x+5) -6 = y
The answer is found by dividing 600 into 450 so your answer is A. 0.75
Answer:
The domain is the input value of x, which can be any real number.
There is no inequality.
Set notation x | E R. ( all real nUmbers)
Interval. Oration (-infinity, infinity)
Range: set x to 0 and solve:
3(0)^2 + 2 = 2
The lowest value is 2 and goes to infinity.
Inequality is >=
Set notation Y | >= 2
Interval notation : [2, infinity)
End behavior they both go to infinity .
