Explanation:
"Without replacement" means the card selected is not put back, and we do not put a copy of that card into the deck.
We have 5 yellow cards out of 5+9+1 = 15 cards total. The probability of picking yellow is 5/15 = 1/3. Let A = 1/3.
After picking that yellow card, we have 5-1 = 4 yellow left out of 15-1 = 14 total. The probability of picking another yellow card, after the first one is not replaced, is 4/14 which reduces to 2/7. Let B = 2/7.
Multiply the values of A and B
A*B = (1/3)*(2/7) = (1*2)/(3*7) = 2/21
The probability of picking two yellow cards, without replacement, is 2/21

do the ratios 8/16 and 2/4 form a proportion
Answer:
Step-by-step explanation:
8/16=8:16
2/4=2:4
Answer:
Yes, the ratios 2/4 and 8/16 form a proportion. To check if two ratios form a proportion, you can cross-multiply and see if the products are equal. In this case, 2 x 16 = 4 x 8 = 32, so the products are equal. Therefore, the ratios form a proportion.

15(n−10)=6−312 what is n
Answer:
ATQ= 15 is 1/5 and 312 is 3/12 sorry for that
1/5(N-10)=6-3/12
1/5N -2= 6/1 - 3/12
1/5N-2 = 72 -3/12 = 69/12
69/2 = 5.75
1/5N = 5.75-2 = 3.75
N= 3.75/.2

In 2012 five US postal stamps cost $2.20 how much did 7 stamps cost
Answer:
Step-by-step explanation:First, divide 2.20 by 5 to find the price of a single stamp.
2.20 ÷ 5 = 0.44
One stamp cost $0.44
Now, you multiply this by 7 to find the cost of seven stamps.
0.44 × 7 = 3.08
In 2012, seven stamps cost $3.08
Answer:
$3.08
Step-by-step explanation:
so 5= 2,20
dividing them will get .44
now multiple by 7
3.08
Adriana is saving to buy a camera for $150. She has $25 in her savings account. Every week she earns $9 an hour babysitting for her neighbor Mrs. Beshara. How many hours will Adrianna need to babysit in order to purchase the camera?
Answer : 14hours
Step-by-step explanation:
If a camera costs 150 dollars and she already has 25 dollars, she needs 125 dollars more
9x14=126 so she needs to works 14 hours
The number of hours needed to babysit in order to purchase the camera is 14.
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
Amount in her account = $25
Amount earned per hour = $9
The expression to find the number of x hours to buy the camera.
25 + 9x = 150
9x = 150 - 25
9x = 125
x = 13.89
x = 14
Thus,
The number of hours needed is 14.

The cost to mail a package is $5.00. Noah has postcard stamps that are worth $0.34 each and first-class stamps that are worth $0.49 each. a. Write an equation that relates the number of postcard stamps p, the number of first-class stamps f, and the cost of mailing the package.
Answer:
[tex]0.34p + 0.49f = 5.00[/tex]
Step-by-step explanation:
Given
[tex]Cost = \$5.00[/tex]
[tex]Postcards = \$0.34[/tex]
[tex]First-class = \$0.49[/tex]
Required
Represent as an equation
If 1 postcard costs $0.34, then p postcards cost $0.34p
If 1 first-class costs $0.49, then f first-class cost $0.49f
The addition of p postcards and f first-class equals the total cost of mailing the package.
So, we have:
[tex]0.34p + 0.49f = 5.00[/tex]

Basically, you start off by taking the number in front of the parantheses (in this case 6) and multiply it with the other numbers inside the parantheses (so that would be 4 and -5). 6 times 4 is 24, 6 times -5 is -30, and now you combine the two numbers (24 and -30).And voila:) !

Answer:
≈ 50.7 cm²
Step-by-step explanation:
The area (A) of Δ XYZ is calculated as
A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height ), that is
A = [tex]\frac{1}{2}[/tex] × XY × YZ
Calculate YZ using the tangent ratio in the right triangle
tan40° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{YZ}{XY}[/tex] = [tex]\frac{x}{11}[/tex] ( multiply both sides by 11 )
11 × tan40° = x , that is
YZ ≈ 9.23 cm
Thus
A = [tex]\frac{1}{2}[/tex] × 11 × 9.23 = 5.5 × 9.23 ≈ 50.7 cm² ( to 3 significant figures )

Anyone know the answer?
Enter the value of x that makes the given equation true.
3(5 - x) = 7x - 2
Answer:
exact form: x=17/10
Decimal form: x=1.7
mixed number form: 1 7/10
Answer:
x = 17/10 (as a fraction) or x = 1.7(as a decimal) or x = 1 7/10(as a mixed number)
Step-by-step explanation:
3(5-x) = 7x - 2
3 * 5 - 3* x = 7x - 2 (brackets means multiply)
15 - 3x = 7x - 2 (when over equal sign negative changed to positive)
15 + 2 = 7x + 3x
17/10 = 10x/10 (cross-cancel cuz u tryna isolate the x)
17/10 = x
