How many integers between 199 and 599 are multiple of 3
Reptile [31]
A.P. series would be: 201, 204, 207 .... 597
Here, a = 201, d = 3, l = 597

Now, l = a + (n - 1) d
597 = 201 + (n - 1)3
597 - 201 = 3n - 3
396 + 3 = 3n
n = 399/3
n = 133

In short, Your Answer would be 133

Hope this helps!

Q and R are not mutually exclusive events. p (q) = 3/5 p(r) = 1/3 and p ( q and r)= 1/5 find P(Q or R).
V125BC [204]
Recall the inclusion/exclusion principle:

\mathbb P(Q\cup R)=\mathbb P(Q)+\mathbb P(R)-\mathbb P(Q\cap R)

which means

\mathbb P(Q\text{ or }R)=\dfrac35+\dfrac13-\dfrac15=\dfrac{11}{15}

Train revived a raise of $80 per week. If he was making $500 per week before the raise, what is the percent change in his earnin
kotegsom [21]

Answer:

Train got a raise of 16%

Step-by-step explanation:

To find this, start by taking the equation for percent change

(New - Old)/Old * 100 = % Change

Now plug in known values

(580 - 500)/(500) * 100 = % change

80/500 * 100 = % change

.16 * 100 = % change

16 = % change

Which of the following rules is the composition of a dilation of scale factor 2, then a translation of three units to the right?
SIZIF [17.4K]

Answer:

The answer is C: (2x +3, 2y)

Step-by-step explanation:

When applying the dilation of a scale factor of 2, you have to apply it to both the x and y coordinate, which means you are multiplying the coordinates by 2.

Let's assume the coordinates you start with are (x, y). Apply the dilation of 2.

(x, y) -----> (2x, 2y)

Now you are moving the figure right. When moving right, this only effects the x coordinate since the x axis moves left and right. Moving right indicates you will add the number of units translated to the x coordinate.

Translation 2 units right:

(2x, 2y) -----> (2x +3, 2y)
