Answer:

The given expression is

$15+c=17.50$

We can use this expression to model the cost for a service.

Let's say that your gardener charges an initial amount of $15, and an additional per hour. If the gardener worked only for one hour, and the total cost charged was $17.50, how much was the additional cost?

So, the given expression models this real life situation, we can answer the problem by just solving the equation for $c$

$15+c=17.50\\c=17.50-15\\c=2.50$

15+c=17.50 First you subtract 15 by 15 because you switch operations from adding to subtracting then you would put C under it Second subtract 17.50 and 15 and that is 2.50 so C= 2.50

Which best describes the polygon whose vertices in the coordinate plane are (-2, 3), (2,3), (2, -1), (-2, 1)?

kondaur [170]

You can see the polygon in the attached figure.

It's a trapezoid, so it's not equilateral, nor regular.

Given two events A and B of a sample set where P[A] = .20 P[not B] = .40 P[B|A] = .25 What is P[A or B]?

kobusy [5.1K]

Answer:

Given two events A and B of a sample set :-

P[A] = 0.20

P[not B]=0.40

$P[B/A]=0.25$

To find P[A or B]:

$P[A or B] = P[A] + P[B] - P[A \cap B]$ ......[1]

Calculate for $P[B]$ and $P[A \cap B]$

P[B] = 1- P[not B]

Substitute the value P[not B] we get;

P[B] = 1-0.40 = 0.60

$P[A \cap B] = P[B/A] \cdot P[A]$

Substitute the given values we get;

$P[A \cap B] = 0.25 \cdot 0.20 = 0.05$

Then;

$P[A or B] = 0.20+0.60-0.05 = 0.80-0.05 =0.75$

Therefore, the value of P[A or B] is, 0.75.

Answer:

y intercept = $(0, ~-\frac{5}{2} )$

x intercept = $(-2, ~0)$

.

Step-by-step explanation:

$-5x - 5y = 10$

.

y intercept

$\to x = 0$

$-5(0) - 4y = 10$

$-4y = 10$

$y = \frac{10}{-4}$

$y = -\frac{5}{2}$

so, the answer is $(0, ~-\frac{5}{2} )$

.

x intercept

$\to y = 0$

$-5x - 4(0) = 10$

$-5x = 10$

$x = \frac{10}{-5}$

$x = -2$

so, the answer is $(-2, ~0)$

.

Happy to help :)
