Answer:

Step-by-step explanation:

From the missing information;

Lets assume that;

$\text{the exponential distribution mean = 500 thousand naira}$

$\text{Range 100 thousand}$ → $\text{1 million naira}$

∴

$X \sim exp (\dfrac{1}{500}) \\ \\ P( X \le x) = 1 - e^{\dfrac{-x}{500}} \\ \\ P(X < 700) = 1 - e^{\frac{-7}{5}} \\ \\ \mathbf{P(X< 700) = 0.75340}$

$Y \sim \cup (100,1000) \implies P(Y \le y ) = \dfrac{y - 100}{1000-100} \\ \\ P(Y < 700) = \dfrac{600}{900} = 0.67$

$P(X < 830)= 1 - e^{\frac{-830}{500}} \\ \\ P(X < 830)= 1 - 0.1901 \\ \\ P(X < 830)=0.8099 \\ \\ P(Y < 830) = \dfrac{730}{900} = 0.8111 \\ \\ Thus;\mathbf{ P(X < 0.8099) = P(Y< 0.8111)}$

I need help please?!!!!

The multiplicative inverse of a number x is a number y such that their product xy is 1.

So, we want a number such that

$10\cdot x = 1$

Divide both sides by 10:

$x=\dfrac{1}{10}$

Find two points where the line intersects with an x and y value that are whole numbers.

The line crosses (0,3) and (-2,-1)

The slope is the change in Y divided by the change in x.

The change in Y is -1 - 3 = -4

The change in x is -2 - 0 = -2

The slope becomes -4 / -2 which simplifies to 2

The answer is D.

150 - x- 2 – 2x = 120 + 2x

dexar [7]

Answer:

First collect like terms on one side

150-2-120=2x+x+2x

148-120=3x+2x

28=5x

Let me change the positions so it could be easier to solve

5x=28

x=28/5

x=5.6

Step-by-step explanation:

I hope I explained well, please give me brainliest
