Answer:

Step-by-step explanation:

Let d be the cost of a drink.  The expression for the cost of the pizza and 4 drinks is

12.75 + 4d

If each drink costs $3, then

12.75 + 4(3) simpifies to

12.75 + 12 which equals 24.75

Find the approximate area of a circle with radius equal to 8 ft. (Use = 3.14.)
Tcecarenko [31]

The area of a circle is given by

A=\pi r^2

If you want to approximate pi with 3.14, the formula becomes

A = 3.14\times 8^2 = 3.14 \times 64 = 200.96

The waiting times between a subway departure schedule and the arrival of a passenger are uniformly distributed between 0 and 6 m
Rudik [331]

Answer: 0.625

Step-by-step explanation:

Given : The waiting times between a subway departure schedule and the arrival of a passenger are uniformly distributed with interval= [0 minutes, 6 minutes]

The probability density function :-

f(x)=\dfrac{1}{6-0}=\dfrac{1}{6}

The interval of  required event = [2.25 seconds, 6 seconds]

Now, the probability that a randomly selected passenger has a waiting time greater than 2.25 minutes is given by :-

\dfrac{6-2.25}{6}=\dfrac{3.75}{6}=0.625

Hence, the probability that a randomly selected passenger has a waiting time greater than 2.25 minutes = 0.625

Which compound inequality can be used to solve the inequality 13x+2/> 7
san4es73 [151]
(3x + 2) < -7 or (3x + 2 >7

Explanation/Step by step:

We have| |3x +2| >7

We divide the absolute value inequality into two inequalities

First Inequality (Which is Positive Value)
(3x + 2) >7

Second inequality (Which is the Negative Value)
-(3x + 2) >7

Then you Multiply by- 1 both sides

~And Remember that when you multiply or divide both sides of an inequality by a negative number you must reverse the inequality Symbol.~

So which that be said it would look like this:
(3x +2) < -7

So therefore (3x + 2) < -7 or (3x + 2) >7

Hope this makes since to you!!
I hope this helps as well..
