The correct answer is:

A. P(both even) = \frac{(_{4}P_{1})(_{3}P_{1})}{_{9}P_{2}}

The expression would determine the probability that both digits are even.

The monthly cost of driving a car depends on the number of miles driven. Lynn found that in May her driving cost was $380 for 48
andrezito [222]

Answer:

y=0.2x+284

Step-by-step explanation:

Let  x be the distance driven, d-distance and C our constant.

Our information can be presented as:

y=mx+c\\\\450=830x+C\ \ \ \ \ \ \ \ \ eqtn 1\\\\380=480x+C\ \ \ \ \ \ \ \ \ eqtn 2

#Subtracting equation 2 from 1:

70=350x\\x=0.2

Hence the fixed cost per mile driven,x is $0.20

To find the constant,C we substitute x in any of the equations:

450=830x+C\ \ \ \ \ \ \ X=0.2\\\therefore C=450-830\times0.2\\=284

Now, substituting our values in the linear equation:

y=0.2x+284       #y=cost of driving, x=distance driven

Hence the linear equation for the cost of driving is y+0.2x+284

*☆*――*☆*――*☆*――*☆*――*☆*――*☆*――*☆*――*☆**☆*――*☆*――*☆*――*☆

Answer: 116.12

Explanation:

13 x 7 = 91

13 - 5 = 8

8 / 2 = 4

3.14(4)^2 = 50.24

50.24 / 2 = 25.12

91 + 25.12 = 116.12

I hope this helped!

Which statement best describes the function below?
harina [27]

Answer:

  • D. It is a many-to-one function

Step-by-step explanation:

  • One-t<em>o-one if every y value has exactly one x value mapped onto it</em>
  • <em>Many-to-one if there are y values that have more than one x value mapped onto them.</em>

We have a function that is of degree 3, so it has 3 x-intercepts which means there are points (x₁, 0), (x₂, 0), (x₃, 0), so it is a many-to-one function

Correct option is D
