NEED RN, WORTH 20! <br> What is the value of x?
max2010maxim [7]

Answer:

x = 5.625

Step-by-step explanation:

<u>Step 1:  Make an expression</u>

<u />\frac{3}{4} = \frac{x}{7.5}

<u>Step 2:  Cross Multiply</u>

<u />\frac{3}{4} = \frac{x}{7.5}

4 * x = 7.5 * 3

4x = 22.5

<u>Step 3:  Divide both sides by 4</u>

<u />4x / 4 = 22.5 / 4

x = 5.625

Answer:  x = 5.625

Suppose x follows a continuous uniform distribution from 1 to 5. determine the conditional probability p(x &gt;2.5 | x ≤ 4).
Rainbow [258]
Because the random variable x follows a continuous uniform distribution from x=1 to x=5, therefore
p(x) = 1/4,  x=[1, 5]
The value of p(x) ensures that the total area under the curve = 1.

The conditional probability p(x > 2.5 | x ≤ 4) is the shaded portion of the curve. Its value is
p(x > 2.5 | x ≤4) = (1/4)*(4 - 2.5) = 0.375

Answer: 0.375

A cannonball is shot straight up into the air. The height of the cannonball at time t is represented by the function f(t)=−16t^2
Karo-lina-s [1.5K]

Answer:

the initial height of the cannon ball

Step-by-step explanation:

- Time (t) is basically how many seconds or minutes you factor into the given function. 16(time in exact seconds or minutes)^2+40(time in exact seconds or minutes) +5

- The +5 can only be where the cannonball was initially fired from logically. The Velocity formula is already there for you to plug the time into^^^


(I used time in minutes/seconds to try and explain what the function is asking)

A taxi service charges one dollar for the first 1/10 of a mile then $.10 for each additional 1/10 of a mile after that
Evgen [1.6K]

Answer:

y  = 1.00+0.10 x (if this is what you meant)

Step-by-step explanation:

Given that a taxi has a minimum charge of 1 dollar upto 1/10 mile and adds 0.10 for every additional 1/10 mile.

If a person travels <=1/10 miles his charges are 1 dollar

If he travels >1/10 miles charges are 1 dollar +0.10(extra miles 1/10)

Let y be the charges and x be the no of 1/10 miles.

Then the equation for y in terms of x would be

y =1.00 +1/10(x)

y  = 1.00+0.10 x
