Answer:

she would find 35 red marbles

Step-by-step explanation:

take the # of red marbles in one bag over the total number of marbles in a bag

5/20

and we know the total of the bags she opens with is 140

essentially it leaves us with x/140

and we're trying to figure out 'x'

so we know that 20 times 7 equals 140 so we do the same to 5 and multiply it by 7 to get 35

PLEASEEE HELP MEEEE!!!
Romashka [77]

Use substitution

From second equation:-

x = 13 - 5y,                   Substitute for x in the first eqaution:

(13 - 5y)^2 + y^2 = 13

169 -130y + 25y^2 + y^2 - 13 = 0

26y^2  - 130y + 156  = 0

26(y^2 - 5y + 6) = 0

26(y - 3)(y - 2) = 0

y = 2 , y = 3

From the second equation when y = 2, x =  13 - 5(2) = 3

and when y = 3,  x = 13 - 5(3) = -2

So the solution is   [3, 2} and {-2, 3}

The data in the tables below were collected from first year students at a community college. The variable is "number of credit c
Oliga [24]

Solution :

It is given that P(x) is said to be complete or proper probability distribution if it satisfies the following two ways :

1. $P(x) \geq 0$

2. $\sum_z P(x) = 1$

Now consider,

$\sum_z P(x) = 1$

⇒ $P(x=0)+P(x=1)+P(x=2)+P(x=3)+P(x=4)+P(x=5)=1$

⇒ $0.61+T+0.14+0.01+0.01+0.03=1$

⇒ $0.8+T=1$

⇒ $T=1-0.8$

       = 0.2

Therefore, the value of T is 0.2

Thus, option (c) is correct.

Rewrite the equation without absolute value <br> Y=|x-2|+|x+2|-|x-5| if x&lt;-2
Oxana [17]

Answer:

Step-by-step explanation:

Hey there!

In order to solve this equation, you need to first simplify and take the absolute value:

x+2+x+2-x+5

Now you need to simplify

x+9

So, the rewritten form of the equation is x+9
