There are a total of 12 balls in the jar, out of which 2 are red and 10 are white.
(a) The probability of picking a red ball on the first draw is 2/12. After the first ball is drawn, there will be 11 balls left in the jar, out of which only one will be red. Therefore, the probability of picking a red ball on the second draw, given that the first ball was red, is 1/11. By the multiplication rule of probability, the probability of both balls being red is:
P(both red) = P(first red) x P(second red|first red)
= 2/12 x 1/11
= 1/66
(b) The probability of picking a white ball on the first draw is 10/12. After the first ball is drawn, there will be 11 balls left in the jar, out of which 9 will be white. Therefore, the probability of picking a white ball on the second draw, given that the first ball was white, is 9/11. By the multiplication rule of probability, the probability of both balls being white is:
P(both white) = P(first white) x P(second white|first white)
= 10/12 x 9/11
= 15/22

Factor completely by grouping: 6x² + 2x + 9x +3
is
Answer:
(2x+3)(x+1)
Step-by-step explanation:
6x² + 2x + 9x +3
(6x² + 2x) + (9x +3)
2x (x+1) + 3 (x+1)
(2x+3)(x+1)
Answer:
(3x+1) ( 2x+3)
Step-by-step explanation:
6x² + 2x + 9x +3
Make the groups
6x² + 2x + 9x +3
Factor 2x out of the first group and 3 out of the second group
2x( 3x+1) + 3(3 x+1)
Now factor out the common term inside the parentheses
(3x+1) ( 2x+3)
what is the factored form of 3/4(24x + 28) - (4x - 1)?
Answer:
2(7x + 11)
Step-by-step explanation:
3/4 ( 24x + 28) - (4x - 1) = 18x + 21 - 4x + 1 = 14x + 22 = 2(7x + 11)
Answer:
2(7x + 11)
Step-by-step explanation:
3/4 (24x + 28) - (4x - 1)
= 18x + 21 - 4x + 1
= 14x + 22
= 2(7x + 11)

boop uwu
Answer:
No solutions
Step-by-step explanation:
4(2r + 3) = 15r - 11 + 1 - 7r
Distribute:
8r + 12 = 15r - 11 + 1 - 7r
Combine like terms:
8r + 12 = 8r - 10
Same to both sides:
0r = -22

Mrs. Norton wants to buy health insurance for her family, Plan A costs $620.50 per month. Plan B costs $597.20 per month. How much will she save in 12 months by choosing Plan B instead of
Plan A?
A $7,446.00
B $7,166.40
C $320.60
D $279.60
Answer:
Step-by-step explanation:

7446 - 7116.4 = 329.6
What is the equation of the axis of symmetry of the parabola y=-2x^2+8x-7?
x=.....
Answer:
Equation of axis of symmetry is x = 2
Step-by-step explanation:
The equation of the parabola is given as;
y = -2x² + 8x - 7
The equation of the axis of symmetry is given by;
x = -b/2a
In the parabola equation given and using letters of quadratic equation, we can say that;
a = - 2
b = 8.
c = -7
Thus;
x = -b/2a = -8/(2 × - 2)
x = 8/4
x = 2
Equation of axis of symmetry is x = 2

Write log7(2 ⋅ 6) + log73 as a single log. Log Subscript 7 Baseline 11 Log Subscript 7 Baseline 15 Log Subscript 7 Baseline 36
Answer:
C. log7 36....................................
The given logarithmic expressions together can be written as log₇ 36
What is a logarithmic function ?The logarithmic function is an expression which we can write as, y = logₐx, where a>0 & x>0, It is the inverse of exponential function.
Formulae for logarithmic function are,
LogAB = LogA + LogB
Logₐaᵇ = b
Given that,
= log₇(2 x 6) + log₇3
= log₇ 36
We have the result
log A + log B = log AB
Here the question is log₇(2 x 6) + log₇3.
Using the property of logarithm we will get,
= log₇(2 x 6) + log₇3
= log₇(2 x 6 x 3)
= log₇ 36
So, log₇(2 x 6) + log₇3 = log₇ 36

Ques
The set of values (63, 64, 65, 66} represents solutions of which inequality?
Answer: 63 < N ≤ 66
Step-by-step explanation:
We have the set:
(66, 64, 65, 66]
First.
When we have an end with the signs "(" or ")" means that the element near the sign does not belong to the set, this would be an "open" end. Usually used for the symbols > and <
While the sign "[" or "]" (in some cases the symbols { and } are used instead)
means that the value next to it are included in the set. Usually used for the symbols ≤ and ≥.
Then in the set: (63, 64, 65, 66} the value 63 does not actually belong, and value 66 does belong.
Then this set is written as:
63 < N ≤ 66
Such that N is an integer number.
