Answer 1

Answer:

Answer:

I believe the answers are C, D, and E. Sorry if I am wrong.

Answer 2

Answer:

2 answers: choice B, choice F

Explanation:

The discriminant is

D = b^2 - 4ac

D = (-5)^2 - 4(3)(-1)

D = 25 + 12

D = 37

This means 37 is under the square root, and we know the answers are B and F due to this. Also note with these two answer choices, they are in the form $(-b \pm √(D))/(2a)$ where...

a = 3, so 2a = 2*3 = 6
b = -5, so -b = -(-5) = 5

Choices A, C, D, and E can be eliminated as the discriminant for these is D = 13.

The probability distribution for a game is shown in the table below.what is the probability of NOT winning a cash prize if the game is played on time?

A) 7/10
B) 1/5
C) 4/5
D) 3/10

Answers

Given:

It is given that

Probability of winning $ 0 = $(3)/(10)$

Probability of winning $ 100 = $(1)/(5)$

Probability of winning $ 200 = $(1)/(10)$

Probability of winning $ 500 = $(2)/(5)$

To find the probability of not winning a cash prize.

Explanation:

Not winning cash prize = winning $ 0

So,

Probability of not winning a cash prize

= Probability of winning $ 0

= $(3)/(10)$

Therefore,

The probability of not winning a cash prize is $(3)/(10)$ . Option D.

x^2 + y^2 ____ x ____ y = 0

Please Help!

Answers

Answer:

$x^(2) + y^(2) -6x+8y= 0$

Step-by-step explanation:

The general equation of the circle is of the form:

$x^(2) + y^(2) +2gx+2fy + c= 0$

The circle passes through the point (0,0), this means replacing x = 0 and y = 0 must satisfy the equation Using these values, we get:

$0^(2) +0^(2)+2g(0)+2f(0)+c=0\nc=0$

This means value of c is zero for the given circle. So, now the equation of the circle is:

$x^(2) + y^(2) +2gx+2fy= 0$

Now using the point, (6, 0) in this equation, we get:

$6^(2)+ 0^(2)+2g(6)+2f(0)=0\n36+12g=0\n36=-12g\ng=-3$

Hence the value of g is -3, using the value of g and c in our equation, the equation becomes:

$x^(2) + y^(2) -6x+2fy= 0$

Now using the 3rd point (0, -8) in this equation to find the value of f:

$0^(2)+ (-8)^(2)-6(0)+2f(-8)=0\n64-16f=0\n64=16f\nf=4$

Using the value of g, f and c, the final equation of the circle is:

$x^(2) + y^(2) -6x+8y= 0$

maria is buying a digital camera on layaway for $193. if she makes a down payment of $25 and pays $24 each week, how many weeks will it take maria to pay for the digital camera.

Answers

Price of the digital camera that Maria is buying from layaway = $193
Amount of money that Maria pays as down payment = $25
Amount of money that Maria pays each week = $24
Let us assume the number of weeks required by Maria to pay for the digital camera = x
then
25 + 24x = 193
24x = 193 - 25
24x = 168
x = 168/24
= 7
So Maria will require 7 weeks to pay for the digital camera.

anwer will be 7 weeks ok and thank u

What is the producr of 5 and 1/8

Answers

There are two easy ways.
The way I was taught:
1. Make 1/8 a decimal by dividing 1 by 8 (Numerator by denominator.), leaving you with 5*.125=.625, or 5/8.
The ACTUAL easy way:
2. Make 5 a fraction by putting it over 1, giving you 5/1*1/8, leaving you with 5/8.

The answer is 5/8 of course
