Answer:
Step-by-step explanation:
B) S = {1,2,3,4,5,6}
n(S) = 6
B = factors of 2 when rolling a single die = {1 , 2}
n(B) = 2
P(B} = 
A) n(S) = 50
A = Picking numbers with 3 in tens place = {30, 31,32,33,34,35,36,37,38,39}
n(A) = 10
P(A) = 
Yes they will please don’t worry about this, colleges are adapting and changing to how students are doing now. Please don’t beat yourself up over this
Step 1.)
7x + 7 * 4.
We need to expand this term by multiplying a term and an expression.
The following product distributive property will be used:
A(B+C) = AB + AC
Numerical factors in this term have been multiplied.
In our example, the resulting expression will consist of 2 terms:
the first term is a product of 7 and x
the second term is a product of 7 and 4.
7x + (7 * 4)
Numerical factors in this term have been multiplied.
Which equals:
7x + 28
Hope you understand this and it helps. Have a great evening!
When x = -1,
y = 12⁻¹ = 1/12 = 0.0833
When x= 0,
y = 12⁰ = 1 = 0.0833*12
When x = 1
y = 12¹ = 12 = 1*12
When x = 2,
y = 12² = 144 = 12*12
When x = 3,
y = 12³ = 1728 = 144*12
The rule is to multiply the previous value of y by 12 as x increases by 1.
Answer: Multiply by 12
The second choice is the correct answer.
X = smaller number, y = larger number
x + y = 15.....x = 15 - y
4x = 2y - 60
4(15 - y) = 2y - 60
60 - 4y = 2y - 60
60 + 60 = 2y + 4y
120 = 6y
120/6 = y
20 = y <==== larger number is 20
x + y = 15
x + 20 = 15
x = 15 - 20
x = - 5
