Q 2. Using a standard deck of cards (which has 26 red cards and 26 black cards, with 13 cards of
every suit), what is the probability of selecting a red card, and then after replacing the card, selecting a
heart card?
Answer:
1/8
Step-by-step explanation:
First Pick P(red card) = 26/52 = 1/2
Second Pick after replacement P(heart) = 13/52 = 1/4
P(red on first pick and heart on second pick
= 1/2 x 1/4 = 1/8

Alan is excited to learn how to ski she went to White peaks Mountain rentals pair of skis for $45 and check for hours of group skiing lessons Alan paid 165 an hour which equation can use to find how much white peaks charges for each hour of group skiing lessons
4(h+45)=165
4h+45=165
45(h+4)=165
45h+4=165
Answer:
4h+45=165
Step-by-step explanation:
The cost of the skates does not fluctuate, therefore it always costs $45 no matter how long you use them for.
Answer:
4h + 45 = 165
Step-by-step explanation:
The question was a little hard to understand, but I made some assumptions based off of the answer choices and the information. If any of the assumptions I made sound incorrect, please don't use my answer!
Based off of the question and answer choices, I'm going to assume that Alan paid an initial price of $45 for the skis and then spent 4 hours skiing for an unknown hourly rate. The total amount of money she spent was $165.
Let h represent the hourly rate. Since Alan spent 4 hours skiing, 4 multiplied by h will represent the amount of money Alan paid for her skiing time.
Alan spent a total of $165. This means that the cost of the skis ($45) plus the cost of her ski time (4h) equals $165. This can be represented in this equation:
4h + 45 = 165

Per Share Seventy-Two Inc., a developer of radiology equipment, has stock outstanding as follows: 60,000 shares of cumulative preferred 3% stock, $20 par and 405,000 shares of $25 par common. During its first four years of operations, the following amounts were distributed as dividends: first year, $30,000; second year, $75,000; third year, $90,000; fourth year, $120,000. Determine the dividends per share on each class of stock for each of the four years. Round all answers to two decimal places. If no dividends are paid in a given year, enter "0.00". 2nd Year 3rd Year Preferred stock (dividends per share). Common stock (dividends per share) 1st Year 0.50 X 4th Year

Cumulative Preferred Common Stock
First-year, $0.50 $0
Second year, $0.70 $0.08
Third year, $0.60 $0.13
Fourth year, $0.60 $0.21
How are the dividends per share determined?The dividends per share for each class can be determined by dividing the allocated dividend by the number of shares in the issue.
The allocated dividend to each class depends on the amount of dividend declared. For cumulative preferred stock, when their fixed dividend cannot be sufficiently settled, the arrears are carried forward.

a city planner wants to build a road perpendicular to D street. What is the slope of the new road?
The slope of the new road is zero.
How to find slope?The slope of a line is the change in y with respect to the change in x.
In other words, the slope of a line is rise over run.
Therefore, the new road the city planner wants to build is perpendicular to the the D street.
(5, 1)(5, 4)
slope of D street = 4 - 1 / 5 - 5
slope of D street = 3 / 0
slope of D street = infinity
An infinite slope is simply a vertical line. Therefore, it is only perpendicular to a horizontal line which will have a slope of 0. Hence, the new road should have a slope of 0.

What is an inequality?
An inequality in mathematics is a relationship that makes a non-equal comparison between two integers or other mathematical expressions. It is most commonly used to compare the sizes of two numbers on a number line. There are multiple notations used to denote various types of inequalities: (i)The symbol a b indicates that an is less than b. (ii)A > b indicates that an is greater than b. In either scenario, a and b are not equal. These are characterized as stringent inequalities because an is either strictly less than or strictly bigger than b. Equivalence is not allowed. In contrast to rigorous inequalities, there are two forms of non-strict inequality relations.

For how many games would the cost be the same? Write and solve an equation to determine the number of games for which the cost would be the same.
For 47 Go golf and 54 golf game would the cost be the same.
Given that -
Go Golf charges -
Ball and club rental = $2.50
For 1 game = $4.25 and
Golf Games charges -
Ball and club rental =$3.25
For 2 game = $8.50
Find out - For how many games would the cost be the same?
Total charges of Go golf per game = $2.50 + $4.25 = $6.75
Total charges of Golf game for 2 games = $3.25 + $8.50 = $11.75
For per game = $11.75 / 2 = $5.875
For Go golf let game = x and
for golf game let game = y
6.75 x = 5.875y

Suppose that y varies directly with x and that y=77 when x=7. What is the value of x when y=55? Responses 50 50 11 11 24 24 5
As y varies directly with x, the numerical value of x when y = 55 is 5.
How to solve direct variation problem?Proportional relationships are relationships between two variables where their ratios are equivalent.
A direct variation equation is a linear equation in two variables.
It is expressed as;
y ∝ x
Hence,
y = k(x)
Where k is proportionality constant.
Given that;
y = 77x = 7Proportionality constant k = ?First, we determine the proportionality constant of the direct variation.
y = k(x)
77 = k(7)
Divide both sides by 7
77/7 = k(7)/7
k = 77/7
k = 11
Now, we find the value of x when y = 55
y = k(x)
55 = 11(x)
Divide both sides by 11
55/11 = 11(x)/11
x = 55/11
x = 5
Therefore, the numerical value of x is 5.
