Answer: D) 1/10

======================================================

Explanation:

Initially there are

2 red beans
1 yellow bean
2 black beans

Giving 2+1+2 = 5 total

The fraction 2/5 represents the probability of picking red

After a red bean is chosen, there's 2-1 = 1 red left out of 5-1 = 4 total. The fraction 1/4 is the probability of getting another red jelly bean.

Multiply those fractions to get the final answer

(2/5)*(1/4) = 2/20 = 1/10

Answer:

2/5

Step-by-step explanation:

There's 5 jellybeans in the bag total and of the five, 2 of them are red, so the probability that Cynthia gives him 2 reds is 2/5.

What is 80+x=200 also, meet my friend group

dedylja [7]

$\huge\text{Hey there!}$

$\huge\textsf{80 + x = 200}$

$\huge\textsf{x + 80 = 200}$

$\huge\text{SUBTRACT 80 to BOTH SIDES}$

$\huge\textsf{x + 80 - 80 = 200 - 80}$

$\huge\text{CANCEL out: 80 - 80 because that gives you 1}$

$\huge\text{KEEP: 200 - 80 because that helps for x}$

$\huge\textsf{x = 200 - 80}$

$\huge\textsf{200 - 80 = x}$

$\huge\textsf{x = 120}$

$\boxed{\boxed{\huge\textsf{Therefore, your answer x = \bf 120}}}\huge\checkmark$

a sugar solution was made by mixing 8 qt of a 2% sugar solution and 6 qt. of a 51% sugar solution. find the concentration of the

melisa1 [442]

16 + 306 = 1400x
322 = 1400x
x = 322/1400
x = 0.23 = 23% (That is the concentration of the mixture)Equation:
sugar + sugar = sugar
0.02*8 + 0.51*6 = x(8+6)

Multiply thru by 100 to get:
-----
2*8 + 51*6 = 1400x

At the store, Jason find the volume of a soda pack is 423.9 in.³. If each cylinder shaped can has a height of 6 inches and a dia

Marina86 [1]

Answer : The correct option is, (A) 10

Step-by-step explanation :

First we have to calculate the volume of cylinder shaped can.

Formula used:

Volume of cylinder = π r² h

where,

r = radius of cylinder

h = height of cylinder

Given:

Diameter of cylinder = 3 in

Height of cylinder = 6 in

Radius of cylinder = $\frac{Diameter}{2}=\frac{3in}{2}=1.5in$

Now putting all the given values in the above formula.

Volume of cylinder = π r² h

Volume of cylinder = 3.14 × (1.5 in)² × 6 in

Volume of cylinder = 42.39 in³

Now we have to determine the number of soda cans are in a pack.

Number of soda cans are in a pack = $\frac{\text{Volume of soda pack}}{\text{Volume of cylinder shaped can}}$

Number of soda cans are in a pack = $\frac{423.9in^3}{42.39in^3}$

Number of soda cans are in a pack = 10

Therefore, the number of soda cans in a pack are 10.

Rearrange the equation so x is the independent variable. 6x+y=4x+11y y=______

Elan Coil [88]

Answer: y = 0.2 x

Step-by-step explanation:

Since, a variable whose variation does not depend on that of another is called independent variable.

Here, given expression is,

6 x +y = 4 x +11 y

⇒ 6 x - 4 x + y = 11 y

⇒ 2 x = 11 y -y

⇒ 2 x = 10 y

⇒ 0.2 x = y

Thus, the value of x does not dependent on the value of y.

Therefore, x is independent variable.

Thus, required answer is y = 0.2 x.
