A number is chosen at random from 1 to 25. Find the probability of selecting an even number or multiple of 3

1 answer:

7 0

First, write highlight the even numbers, then the multiples of 3
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25
No, count how many have been highlighted at least once
16 out of 25 were highlighted
16/25

Or, there are 12 even numbers between 1 and 25. There are also 8 multiples of three, however half will be even
8/2 = 4
4 + 12 = 16
16/25

For the following figure, complete the statement for the specified points.

AVprozaik [17]

The correct answer is coplanar

EXPLANATION

Coplanar means the three points A , B and Q are on the same plane.

They are not colinear, because they are not in a straight line. It is only A and Q that are on the same straight line. If B had fallen in line with them, the three points would have been collinear as well.

Use the graph that shows the solution to F(x) = G(x)

Alisiya [41]

Answer: B. 0 and D. 3

Step-by-step explanation:

Here the given function is,

$f(x) = \frac{7}{3}x-3$

$g(x) = 2^x-4$

For finding the solution of this system of equation,

First we will plot the function on the graph,

Graph of function f(x),

x-intercept and y-intercept are (1.286,0) and (0,-3) respectively,

Also, it is a straight line,

Hence, we can plot this line on the graph,

Graph of function g(x),

Function g(x) is an exponential function having x-intercept and y -intercept, (2,0) and (0,-3) respectively.

Also, the end behavior is,

As $x\rightarrow \infty$ , $f(x)\rightarrow \infty$

As $x\rightarrow -\infty$ , $f(x)\rightarrow -4$

Hence, we can plot the graph of g(x),

By plotting the graph,

We found that the intersection of the function f(x) and g(x) are (0,-3) and (3,4).

Hence, the solution of the system is the x-coordinates of the intersection points that are 0 or 3.

⇒ Option B and C is the correct options.

A manufacturer has a monthly fixed cost of $110,000 and a production cost of $14 for each unit produced. The product sells for $

vova2212 [387]

Answer:

Cost function C(x) == FC + VC*Q

Revenue function R(x) = Px * Q

Profit function P(x) =(Px * Q)-(FC + VC*Q)

P(12000) = -38000 Loss

P(23000) = 28000 profit

Step-by-step explanation:

Total Cost is Fixed cost plus Variable cost multiplied by the produce quantity.

(a)Cost function

C(x) = FC + vc*Q

Where

FC=Fixed cost

VC=Variable cost

Q=produce quantity

(b)

Revenue function

R(x) = Px * Q

Where

Px= Sales Price

Q=produce quantity

(c) Profit function

Profit = Revenue- Total cost

P(x) =(Px * Q)-(FC + vc*Q)

(d) We have to replace in the profit function

<u>at 12,000 units </u>

P(12000) =($20 * 12,000)-($110,000 + $14*12,000)

P(12000) = -38000

<u>at 23,000 units </u>

P(x) =($20 * 23,000)-($110,000 + $14*23,000)

P(23000) = 28000
