The required inequality is p≥9

Step-by-step explanation:

Given condition:

Lindsay needs to interview a minimum of 15 people.

Lindsay completed interviewing 6 people.

To Find:

The possible number of people she still needs to interview to complete her project.

Solution:

Let p be the number of people needed to complete the project.

To complete the project Lindsay needs to interview minimum 15 people.

i.e.p≥ 15

But she has already interviewed 6 people. so, (15-6) = 9

i.e p+6≥15

or, p+6≥15

∴ p≥9

Hence the inequality that shows the people she still needs to interview to complete the project is p≥9.

What’s the equation.?

Stella [2.4K]

Answer:

See below

Step-by-step explanation:

You know that he spent 1/3 of his earnings, and then 1/4. After this, he has $28.90. You can write the equation like this:

1/4(x * 1/3) = $28.90.

If you need to solve it:

1/4 * 1/3x = 28.90

1/12x = 28.90

x = 346.80

A van and a truck both drove from Town A to Town B. The distance

Gala2k [10]

First we need to find out the time it took for the truck to reach town B.

$Speed= \frac{Distance}{Time}$

$40= \frac{200}{T}$
$T=5hours$

Now, because the van left 1.5 hours earlier and reached the destination 2.5 hours before, it took 1 hour less the the truck to arrive.

$5hours-1hour=4hours$ which is the time it took for the van to arrive.

Now we use the speed equation again to work out speed.

$Speed= \frac{200}{4}$

$Speed=50mph$ = speed of van

Hope this helped :)

A daily mail is delivered to your house between 1:00 p.m. and 5:00 p.m. Assume delivery times follow the continuous uniform dist

german

Answer:

25% of deliveries

Step-by-step explanation:

This is a uniform distribution with parameters a = 1.00 and b =5.00. With these conditions, the following probability distribution functions can be applied:

$P(X \leq x)=\frac{x-a}{b-a}=\frac{x-1.00}{5.00-1.00}\\P(X \leq x) = \frac{x-1}{4}\\P(X \geq x) = 1- P(X \leq x) \\P(X \geq x)=1- \frac{x-1}{4}$

Therefore, the probability that X ≥ 4:00 p.m. is given by

$P(X \geq 4)=1- \frac{4-1}{4}\\P(X \geq 4)=0.25=25\%$

Thus, 25% of deliveries are made after 4:00 p/m.
