how many real solutions will y=x^2 and y=-2x have? what are the solutions?

Answers

Answer 1

Answer:

there is none

Step-by-step explanation:

Answer 2

Answer:

No solutions

Step-by-step explanation:

Real number solutions only or real and complex solutions. A solution to the system:

y=-2x+2

y=x2-2x+4

is the value of x such that when you plug it into both equations, they both produce the same value of y, or the value of x such that

-2x+2=x2-2x+4

solving this equation----------> x2=-2, taking square root of both sides gives x= ±√2i, or the system has no real solutions but has 2 complex solutions. If you graph both functions in the xy-plane, where x, y are real numbers, you' ll see they do not intersect, which implies there is no real number solutions.

Mr Thompson wants to cut a 5-ft rope into a 1/4-ft sections how many 1/4 sections will he have

Answers

Answer:

20 pieces of rope

Step-by-step explanation:

Mr. Thompson has a 5-ft rope. If he cuts the rope into 1/4-ft pieces, that means for every foot, there are 4 pieces of rope. There are 5-ft of rope, so we multiply 5 and 4 to get the number of pieces of rope.

5 x 4 = 20 pieces of rope.

Lila has $35.55. She buys a magazine for $3.15, a cookie for $2.20, and a shirt for $14.99. She also gets $5 from a friend. How much money does she have after the above transactions?
A)$10.21
B)$14.61
C)$16.51
D)$20.21

Answers

Answer:

$20.21

Step-by-step explanation:

$35.55 - $3.15 = $32.40

$32.40 - $2.20 = $30.20

30.20 - $14.99 = $15.21

$15.21 + $5.00 = $20.21

The answer is D

$35.55 - $3.15 = $32.4 $32.4 - $30.2 $30.2 - $14.99 = $15.21 $15.21 + $5 = $20.21

Three cards—one red, one green, and one blue—are to be arranged in a stack. Using R for red, G for green, and B for blue, make a list of all the different stacks that can be formed. (Some computer monitors are called RGB monitors for the colors red, green, and blue. Enter your answers as a comma-separated list.)

Answers

Answer:

RGB. RBG, BRG, BGR, GBR, GRB

Step-by-step explanation:

Given

R, G and B

Required

List all possible arrangement

First, we need to calculate the number of arrangement

There are 3 letters and they are to be arranged in order of 3.

So, we have:

[tex]n = 3[/tex] and [tex]r =3[/tex]

Number of arrangement is:

[tex]^nP_r = \frac{n!}{(n - r)!}[/tex]

[tex]^3P_3 = \frac{3!}{(3 - 3)!}[/tex]

[tex]^3P_3 = \frac{3!}{0!}[/tex]

[tex]^3P_3 = \frac{3*2*1}{1}[/tex]

[tex]^3P_3 = \frac{6}{1}[/tex]

[tex]^3P_3 = 6[/tex]

Hence, number of arrangements is 6 and the arrangements are:

RGB. RBG, BRG, BGR, GBR, GRB

In the 2017 national Youth Risk Behavior Survey, 16.5% of high school students had ridden with a driver who had been drinking alcohol within the previous month. This data came from an SRS of 14,500 students. what is the mean and standard deviation

Answers

Answer:

[tex]Mean = 2392.5[/tex]

[tex]SD = 44.70[/tex]

Step-by-step explanation:

Given

[tex]Students = 14500[/tex]

[tex]p = 16.5\%[/tex]

Solving (a): The mean

Mean is calculated as thus:

[tex]Mean = np[/tex]

[tex]Mean = 16.5\% * 14500[/tex]

Convert % to decimal

[tex]Mean = 0.165 * 14500[/tex]

[tex]Mean = 2392.5[/tex]

Solving (b): The Standard Deviation

Standard deviation (SD) is calculated as thus:

[tex]SD = \sqrt{np(1-p)}[/tex]

[tex]SD = \sqrt{14500 * 16.5\%(1-16.5\%)}[/tex]

Convert % to decimal

[tex]SD = \sqrt{14500 * 0.165 * (1-0.165)}[/tex]

[tex]SD = \sqrt{14500 * 0.165 * 0.835}[/tex]

[tex]SD = \sqrt{1997.7375}[/tex]

[tex]SD = 44.6960568731[/tex]

[tex]SD = 44.70[/tex]
