5 0

Every few days, on my way home from work, I pull into Ahmad's
Friendly Fuel and fill up my car's gas tank.

His price has been $2.29 per gallon for almost 4 years now, and it still is.

I don't always buy the same amount of gas, but no matter how much I buy,
my cost always fits the linear equation ...

Cost = (2.29) · (number of gallons) dollars.

What is -√169? (note: negative in front of the √)

Mademuasel [1]

Hello!
Ignore the negative and solve the square root which is 13.
Add the negative with 13 you get -13
Special case is when it is square root of -169 then it will involved with i.
But for this question just solve it directly.
Have a great day!

James is buying a table.He finds the same table for sale in two different shops.

mina [271]

"Table World" is quoting a better price

<u>Step-by-step explanation:</u>

The shop "Table World" is quoting a price of 140 inclusive of 17.5% VAT

that means 140 is the final price a customer needs to pay.

While other shop"Tables R us" is quoting a price of 120 without VAT

so we need to add VAT in the price to find out the final price

price+VAT on the price

=120+120*(17.5/100)

=120+120*0.175

=120+21

so final price =141

so comparatively "Table World" is quoting a better price

Solve the formula V=pir^2h for r <br><br> PLEAASSSEEE HELP

otez555 [7]

Answer:

Step-by-step explanation:

So we have the formula:

$V=\pi r^2h$

And we want to solve it for r.

So, let's first divide both sides by π and h. This will cancel out the right side:

$r^2=\frac{V}{\pi h}$

Now, take the square root of both sides:

$r=\sqrt{\frac{V}{\pi h}}$

And we're done!

Our answer is B.

I hope this helps!

The reaction time (in seconds) to a certain stimulus is a continuous random variable with pdf f(x) 5 5 3 2 ? 1 x2 1

muminat

The probability that the reaction time for this density function is at most 2.5 seconds is equal to 0.9.

<h3>What is a density function?</h3>

A density function can be defined as a type of function which is used to represent the density of a continuous random variable that lies within a specific range.

<h3>How to calculate the probability that reaction time is at most 2.5 seconds?</h3>

P(X ≤ 2.5) = Fx(2.5)

Fx(2.5) = 3/2 - 3/2(2.5)

Fx(2.5) = 3/2 - 3/5

Fx(2.5) = 0.9.
