A box of donuts containing 6 maple bars, 3 chocolate donuts, and 3 custard filled donuts is sitting on a counter in a work offic

Svetlanka [38]

Probabilities are used to determine the chances of selecting a kind of donut from the box.

The probability that Warren eats a chocolate donut, and then a custard filled donut is 0.068

The given parameters are:

$\mathbf{Bars = 6}$

$\mathbf{Chocolate = 3}$

$\mathbf{Custard= 3}$

The total number of donuts in the box is:

$\mathbf{Total= 6 + 3 + 3}$

$\mathbf{Total= 12}$

The probability of eating a chocolate donut, and then a custard filled donut is calculated using:

$\mathbf{Pr = \frac{Chocolate}{Total}\times \frac{Custard}{Total-1}}$

So, we have:

$\mathbf{Pr = \frac{3}{12}\times \frac{3}{12-1}}$

Simplify

$\mathbf{Pr = \frac{3}{12}\times \frac{3}{11}}$

Multiply

$\mathbf{Pr = \frac{9}{132}}$

Divide

$\mathbf{Pr = 0.068}$

Hence, the probability that Warren eats a chocolate donut, and then a custard filled donut is approximately 0.068

what is the value of a for the exponential function in the graph represented in the form of f(x)=a(b^x)? Zoom in the photo bcz i

nekit [7.7K]

Answer:

$a = 3$

Step-by-step explanation:

To determine the value of $a$ , we want $b^x$ to be 1, so that $f(x) = a \times 1$ . Notice that if $x = 0$ , then $f(0) = a \times (b^0) = a$ , so the value of $a$ is simply $f(0)$ . From the graph, it appears that $f(0) = 3$ , so therefore $a = 3$ .

A rectangle's length and width are in a ratio of 11:3. The perimeter is 56 feet. What are the length and width?

frozen [14]

Answer:

Length=44feet

Width=12feet

Step-by-step explanation:

length:width=11:3

Perimeter=56feet

Sum of ratio=11+3

Sum of ratio=14

Length=11/14 x 56

Length=(11 x 56)/14

Length=616/14

Length=44feet

Width=3/14 x 56

Width=(3 x 56)/14

Width=168/14

Width=12feet

This year, a small business had a total revenue of $40,700. If this is 26% less than their total revenue the previous year, what

Virty [35]

26% less than a value is best found by multiplying by (100 - 26)% = 74% = 0.74
So previous year x 0.74 = 40,700
Previous year = 40,700 / 0.74 = $55,000

If (a+b) / (x−y) = 3/5 then (10a + 10b) / (9x−9y) = ?

lbvjy [14]

Answer:

2/3

Step-by-step explanation:

Look at what you are getting on the right hand question. 10a +10b has a common factor that can be pulled out. It is 10

10a + 10b = 10(a + b)

Now look at the denominator

9x - 9y = 9(x -y)

There are a lot of possible answers.

Mine would be to multiply 3/5 * 10/9

$\dfrac{3}{5}*\dfrac{10}{9} = \dfrac{30}{45} = \dfrac{2}{3}$

so

(10a + 10b)/(9x - 9y) = 2/3
