2. Ajar contains 10 marbles, 6 marbles are red, and 4
marbles are blue. If 2 marbles are chosen one at a time
without replacement, what is the probability that the first
marble will be blue and the second marble will be red?
A: 3/16 B: 6/25 C: 1/8 D : 12/45
Independent or Dependent:
Final Answer:
Answers
Answer:
A
Step-by-step explanation:
Note that there are 16 total marbles. A is simply a set of sequential events. On the first, you have 10/16 chances to draw a red. Supposing this red is not replaced, the chance of drawing a second red will be 9/15; therefore, the probability of A is (10/16) * (9/15) = 0.375. Event B is translated into 2 events: Blue + (White or Red) or (White or Red) + Blue. The probabilities of each of these events, added together would be (2/16) * (14/15) + (14/16) * (2/15) = 0.2333333333; therefore, A is more probable.
Write the equation of the line in slope-intercept form (y = mx + b) that has a slope of 4 and passes through the point (0,2).

Answer:
I need a graph.
Step-by-step explanation:
You can also use rise over run to help you. However if you are stating me that 4 is slope. Then it will be y=4x+ something because I am not sure if 2 is the y intercept even though its on the y-axis.
4. Your job as a carpenter pays $20/hour and you worked 40 hours last week. The taxes
withheld from your wages were $83 federal tax and $19 state tax. Your total check is
a. $698
b. $720
c. $810
d. $912
Answers
Answer:
698.00 (A)
Step-by-step explanation:
20.00x40=800.00
83.00+19.00=102.00
800.00-102.00=698.00
The total amount of the check will be $698. Then the correct option is A.
What is Algebra?The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
Your job as a carpenter pays $20/hour and you worked 40 hours last week.
Then the amount that you earn in 40 hours will be
⇒ $20 x 40
⇒ $800
The taxes withheld from your wages were $83 federal tax and $19 state tax. Then the total amount of the check will be
⇒ $800 - $83 - $19
⇒ $800 - $102
⇒ $698
The total amount of the check will be $698. Then the correct option is A.

Solve the equation for y. Type out your steps to solve this problem as you are showing your work:
7(y + 3) = 5y + 8
Answers
Answer:
-13/2
Step-by-step explanation:
7(y+3)=5y+8
7y+21=5y+8
7y-5y+21=8
2y+21=8
2y=8-21
2y=-13
y=-13/2
Answer:
y = -6.5
Step-by-step explanation:
simplify: 7y+21=5y+8
put like-terms together and simplify: 2y=-13
(like-terms: 7y-5y=8-21)
divide both sides by 2: y=-6.5

In the year 1984 the average American used to eat 55.7 pounds of chicken. This was 2.8 pounds more than the the year 1982 average. By what percent did chicken consumption increase from the year 1982 to the year 1984?
Answers
To solve this, we need to use the z statistic. The formula for z score is:
z = (x – u) / s
where x is sample value = less than 90, u is the sample mean = 90.6, s is the standard deviation = 17.2
z = (90 – 90.6) / 17.2
z = -0.035
From the standard distribution tables:
P (z = -0.035) = 0.4860
Therefore there is about 48.60 % chance that it will be less than 90 pounds
Answer:
I think it increased by 0.05.
Step-by-step explanation:
If you subtract 2.8 from 55.7 you'll get 52.9. So I would divide 55.9 by 52.9 and get 1.05. I then would subtract 1.0
Which expression is equivalent to ( xy -6)2 for all values of x and y where the expression is defined?

Answers
Answer: -3π/2
Step-by-step explanation:
The unit circle is tricky, but here are some things to know:
When measuring angles, you usually move in the counter-clockwise direction. If you are moving clockwise (like shown in your picture), the angle will be negative. The unit circle is typically measured in radians, not degrees- To convert from radians to degrees, multiply by 180/π
- To convert from degrees to radians, multiply by π/180
The whole unit circle measures 2π (360 degrees). This means that the positive x-axis can be referred to as 0 or 2π, the positive y-axis is referred to as π/2, the negative x-axis is referred to as π, and the negative y-axis is referred to as 3π/2.-If the angle is negative, switch the signs of the axis above.
The information above is all you need to answer the above question, but if you want/need anything else on the unit circle, just let me know.
