Answers
1.) 11d-(18)=-7
We combined like terms, in this case the constants -4 and -14. -4-14 = -(14+4) = -18. So, first step is -4-14.
2.) 11d=11
The additive inverse of -18 is 18, so we canceled it out from the left and combined it with the content of -7 on the right to isolate 11d.
3.) d=1
We divided 11d by 11 to cancel it out, and we divided 11 by 11 on the left.

A game of Blackjack or “21” is played with a regular deck of cards. The aim of the game is to have cards that add up to 21. The cards are not replaced to the deck once they have been drawn. If you draw two cards in a row, what is the probability of getting 21, when first card you get is an ace and the second card is a queen?
Answers
The probability of getting 21, when first card is an ace and the second card is a queen = 0.024133.
The term blackjack means that you get a value of 21 with only two cards.
Number of cards in a deck of cards = 52
There are 4 types of cards in a deck of cards - spades, clubs, hearts, and diamonds, out of which spades and clubs are black in colour.
Given that first card is Ace and second one is a Queen.
Odds of getting an Ace are 4/52, odds of the next being Queen is 16/51.
P(blackjack)=4×16/(52/2).
where P is used for probability .
Probability: Probability is simply how likely something is to happen. Whenever we are unsure about the outcome of an event, we can talk about the probabilities of certain outcomes. The analysis of events governed by probability is called statistics.
Probability of getting an ace followed by a queen card: 4/52 * 16/51 = 0.024133.

In 2016, 6.76% (1,026) of Cincinnati college and university graduates majored in Registered Nursing. That combined statement provides both the percentage (6.76%) and the number (1,026) of Cincinnati college and university students who majored in Registered Nursing in 2016. Based on that statement, how many students graduated from Cincinnati universities and colleges altogether in 2016? Round to the nearest whole number.
Answers
The total number of students who graduated from the Cincinnati universities and colleges are 15382.
We are given that 6.76 % of Cincinnati college and university graduates majored in Registered Nursing.
The number of the Cincinnati college and university graduates who majored in Registered Nursing = 1026.
We need to find the total number of students that graduated from the Cincinnati universities and colleges altogether in 2016.
Let the total number of students be x.
ATQ:
6.67 % x = 1026
6.67 x = 102600
667 x = 10260000
x = 10260000 / 667
x = 15382.309
Rounding off to the nearest whole number is:
x = 15382.
Therefore, we get that the total number of students who graduated from the Cincinnati universities and colleges are 15382.

The average annual wage of workers in the country will be at least $68400 in the year 2023 and after , the correct option is option (B) .
In the question it is given that
model of the average annual wage (y) = 2286x + 38620 ...(i)
where x = number of years after 2010,
It is also given that the average annual wage(y) must be at least 68,400 .
which means y ≥ 68400
Substituting value of y from equation (i) we get ,
2286x + 38620 ≥ 68400
Simplifying the inequality further we get ,
2286x ≥ 68400 - 38620
2286x ≥ 29780
x ≥ 29780/2286
x ≥ 13.02 ≅ 13
Hence , the average annual wage will more than the specified value from the year, 2010+13 = 2023 .
Therefore , the average annual wage of workers in the country will be at least $68400 in the year 2023 and after , the correct option is option (B) .

The sum of two numbers is -316. One number is 94 less than the other. Find the numbers
Answers
Explanation:
Using the description, we can set up equations to solve for the two numbers. First we assign variables to the numbers: Number 1 will be “x” and number 2 will be “y”.
For the first part [The sum of two numbers is -316] the equation will be:
x + y = -316
For the second part [One number is 94 less than the other] the equation will be:
x = y - 94
Those two equations give us a system of equations we can use to solve for the variables.
Equation 1: x + y = -316
Equation 2: x = y - 94
Since we have an equation for what x is (equation 2), we can substitute that into equation 1 and solve for y.
x + y = -316
(y - 94) + y = -316
[combine the ys]
2y - 94 = -316
[add 94 to both sides]
2y = -222
[divide by 2]
y = -111
Plug y into one of the equations and solve for x and you get: x = -205
