It is a continuous random variable, so calculating for ✓, we have
10=E(x)1/✓
✓=1/10=0.1
1)P(x>60)=1-F(60)=e^0.1x60=0.0025
2) Employing lack of memory property, we have, P(X<70|X>60)=P(X<10)= F(10)=1-e^-0.1x10= 0.63
3) for 0.1, x= -1/0.1 ln0.1= 23
4) for 0.9, x= -1/0.1 ln 0.9= 1.053
5) for 0.5, x -1/0.1 ln 0.5= 6.3

When we evaluate the quotient functions, (mn)(x) for x = -3
(mn)(-3) = 9 and (m/n) (x), x ≠ 0
How did we evaluate the quotient function?To evaluate the quotient function (mn)(x) for x = -3, we substituting x = -3 into the function mn(x).
This gives us (mn)(-3) = m(-3) × n(-3) = (-3)² × (-3) = 9.
We then need to evaluate (m/n)(x), x ≠ 0.
This is done by dividing the function m(x) by the function n(x). This gives us (m/n)(x) = m(x) / n(x) = x^2 / x = x. However, this expression is undefined when x = 0, because division by zero is undefine

A perfect square means that all side are EXACTLY equal. I hope this helps!
Step-by-step explanation:
In number theory, a perfect number is a positive integer that is equal to the sum of its positive divisors, excluding the number itself. For instance, 6 has divisors 1, 2 and 3, and 1 + 2 + 3 = 6, so 6 is a perfect number

Lucy invested $19,000 in an account paying an interest rate of 3% compounded annually. Assuming no deposits or withdrawals are made, how much money, to the nearest hundred dollars, would be in the account after 8 years?
Answer: 24100
Step-by-step explanation:
The money in the account after 8 years is $24068.631.
Given that, principal=$19000 and the rate of interest=3%.
What is the formula to find the compound interest?The formula to find the compound interest is CI=A-P.
Where, A=Amount that is [tex]A=P(1+\frac{r}{100} )^{n}[/tex], P=principal.
Now, [tex]A=19000(1+\frac{3}{100} )^{8}[/tex]
=19000[tex](1.03)^{8}[/tex]
=19000×1.26677008139
=$24068.6315464
=$24068.631
Therefore, the money in account is $24068.631.

1. The county fair charges $1.25 per ticket for the rides. Jermaine bought 25 tickets for the rides and spent a total of $43.75 at the fair. Jermaine spent his money only on ride tickets and fair admission. The price of the fair admission is the same for everyone. Use y to represent the total cost and x to represent the number of ride tickets.
(a) Define your variables.
(b) Write a linear equation that can be used to determine the cost for anyone who only pays for ride tickets and fair admission.

What is the relationship between DG and FG?
O A. DG is parallel to FG
O B. DG is perpendicular to FG.
OC DG Intersects FG to form an acute angle.
ODDO intersects FG to form an obtuse angle
Answer:
Option B
Step-by-step explanation:
From the figure attached,
Circle D is drawn with the radius = DG or DE
A tangent FG has been drawn at a point G on the circle from an external point F.
By theorem,
Radius of a circle is always perpendicular to the tangent, drawn to the circle from an external point.
Therefore, DG ⊥ FG.
Option B will be the correct option.

What is the slope of a line perpendicular to the line whose equation is
2x+12y=−192. Fully reduce your answer.
The slope of a line would be -6 which is perpendicular to the line whose equation is 2x+12y=−192.
What is the slope of the line?The slope of a line is defined as the angle of the line. It is denoted by m
Slope m = (y₂ - y₁)/(x₂ -x₁ )
We have to determine the slope of a line perpendicular to the line whose equation 2x + 12y = −192.
First, we have to find the slope of the given line
The equation of the line which is given as
2x + 12y = −192
12y = −192 - 2x
Divided by 12 both sides of the above equation to get the slope-intercept form
y = - (1/6)x - 16
Here the slope of the line (m) = -1/6
So the slope of the line perpendicular to the line will be: 1/m = 1/(-1/6) = - 6.

To boil rice, start by combining water and rice in a pot at a ratio of 3:1. How many cups of water are need for a batch that uses eight cups of rice?
Answer:
Step-by-step explanation:
To boil rice you use the following ratio
Water : Rice
3 : 1
? : 8
Basically what the ratio 3:1 means is that for every 3 cups of water, you need 1 cup if rice.
6 cups of water, you need 2 cups of rice (6:2)
9 cups of water, 3 cups of rice (9:3)
Etc.
All you would have to do is multiply 3 by 8 to find out how much water she needs for 3 cups of rice :)
Answer:
ok the ratio of water to Rice is 3:1 meaning water is 3 rice is one and your child that we have 8 cups of rice so really quite the ratio of rice to the number of cups of rice so it will be if one is equals to 8 what about 3 that is the ratio that represents water so we'll cross multiply so that you have 3 * 8/1 and the answer is 24 so the number of cups of water needed is 24
