probability of drawing two blue marbles= 5/10
= 1/2
Given parameters:
Number of marbles in the bag = 10 marbles
Number of blue marbles = 5 marbles
Number of red marbles = 4 marbles
Number of yellow marbles = 1 marble
Unknown:
The probability of drawing two blue marbles.
Probability is the likelihood of an event to occur. It is the number of possible outcomes divided by the sample space.
Probability values ranges from 0 to 1
1 is a certainty that an event will occur.
0 shows that the event will not occur.
The probability of drawing the first blue marble = [tex]\frac{5}{10}[/tex]
Probability of drawing the second marble without replacing the marble = [tex]\frac{4}{9}[/tex]
Now,
The probability of drawing two blue marbles without replacement is;
= [tex]\frac{5}{10}[/tex] x [tex]\frac{4}{9}[/tex]
= [tex]\frac{2}{9}[/tex]
So the probability of picking two marbles without replacement is [tex]\frac{2}{9}[/tex]

=-6a-48
Find the value of x when 6 - 2x = 6x - 10x + 18
Answer: x=6
Step-by-step explanation: in this equation you're trying to
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
6-2*x-(6*x-10*x+18)=0
Pull out like factors :
-12 + 2x = 2 • (x - 6)
x-6 = 0
Add 6 to both sides of the equation :
x = 6

Suppose you walk 2 miles in 35 minutes. 4. write a proportion to find how far you would walk in an hour if you were to continue at the same rate.
Answer:
2/35 * x/60
Step-by-step explanation:
the x is what you're trying to find. the 60 is how many minutes there are in an hour. when setting up this proportion, you can't put 1 for 1 hour because you have 35 minutes. if it says minutes, then keep everything in minutes. from here, you would cross multiply and solve, that should give you the answer :) hope this helps <3

a
Undefined
b
Negative
c
Zero
d
Positive
Answer:
A, undefined
Step-by-step explanation:
The general rule is that vertical lines are undefined slope, because there's literally no change in x values. The vertical line test also fails, meaning there is no slope. Horizontal lines have a slope of 0, while vertical lines don't own any numbers that are important except for x-axis numbers.
If you do y2-y1 over x2-x1, you literally get 1/0 which is nothing. 0/1 = 0, but 1/0 is nothing.

You have been waiting for months. The latest version of your favorite video game comes out today. You have mowed lawns, done extra chores, and saved up gift money. The new game costs $49.99. You have exactly $50.00 saved. So you are good to go, right? In 3 to 5 sentences explain if you have enough money to buy that game in Pennsylvania where sales tax is 6% If you have enough money, will you have change? If you do not have enough money, how much more do you need?
The savings are not enough to buy the video game due to sales tax and $ 2.99 is needed more to buy the latest version of favorite video game.
What is the formula to calculate sale tax ?The sales tax is calculated by multiplying the cost price by the rate of sales tax.
Amount of sales tax = rate of sales tax × Cost price
Rate of sales tax = percent of sales tax / 100
Savings money = $ 50.00
Cost price = $ 49.99
Given percentage of Sales Tax = 6%
Amount of sales tax = (sales tax/ 100 ) × $ 49.99
= (6/100)× 49.99
= 2.9994
Total Selling price of the video game will be = cost price + sales tax
= 49.99 + 2.9994
= $ 52.9894
= $ 52.99
Selling price is greater than savings it means more money is needed to buy the video game.
Extra money needed = Selling price - savings = $52.99 -$ 50.00= $ 2.99
Therefore, $ 2.99 is needed more to buy the latest version of favorite video game

Twice the sum of a number and nine is 24. Find the number.
Answer:
3
Step-by-step explanation:
2 (n + 9) = 24 this is the equation
to solve for n (number):
2(n+9)=24 // Distribute the 2 into parentheses
2n + 18 = 24 // Subtract 18 on both sides of equal sign
- 18 -18
2n = 6 // Divide by 2 on both sides of equal sign
2 2
n = 3

A In this triangle, the product of tan A and tan Cis
Answer:
1
Step-by-step explanation:
The value of product of expression tan A and tan C is,
⇒ tan A × tan C = 1
Here, We have;
In triangle ABC;
⇒ ∠ A = 45°
⇒ ∠ B = 90°
⇒ ∠C = 45°
Hence, We get;
The value of product of tan A and tan C is,
⇒ tan A × tan C =
⇒ tan 45° × tan 45°
⇒ 1 × 1
⇒ 1
Thus, The value of product of expression tan A and tan C is,
⇒ tan A × tan C = 1
