There are 4 jacks and 13 clubs in a standard, 52-card deck of playing cards. What is the probability that a card picked at random from a standard deck of playing cards is a club or a jack?
Answer:
16/52, or 4/13.
Step-by-step explanation:
First, since we know that the question is asking for the probability of a club or a jack, we know that we have to add the two probabilities. The first probability is that of picking a club, which is 13/52. The probability of picking a jack (be sure not to overlap; don't double count the jack of clubs) is 3/52. Adding these two gives us 13/52+3/52=16/52, which simplifies to 4/13.

A certain company gives its salespeople a bonus every six months. This bonus is calculated by averaging (taking the mean of) the four middle monthly sales values (that is, ignoring the highest and lowest) from the six-month window, taking 12% of the result, and splitting it evenly among the salespeople. The graph below shows sales for the most recent bonus period. A bar graph titled Total Sales has month on the x-axis and sales (dollars times 1,000) on the y-axis. January, 21.6; February, 18.9; March, 29.2; April, 18.4; May, 17.1; June, 26.1. If there are five salespeople, how much money will each one receive, to the nearest dollar? a. $556 b. $525 c. $510 d. $486
Answer:
The answer is C. $510.
I have just took the test.
Option C is correct, Each person receives an amount of $510.
What is Graph?Graph is a mathematical representation of a network and it describes the relationship between lines and points.
To calculate the bonus, we need to find the four middle monthly sales values.
Arranging the sales values in ascending order, we get:
17.1, 18.4, 18.9, 21.6, 26.1, 29.2
The four middle values are: 18.4, 18.9, 21.6, and 26.1.
Average= (18.4 + 18.9 + 21.6 + 26.1) / 4 = 21.25
Taking 12% of this value gives:
0.12 x 21.25 = 2.55
The bonus amount to be split among the five salespeople is $2.55. Therefore, each salesperson will receive:
2.55 / 5 = 0.51
Therefore, each salesperson will receive $1 as a bonus.
Hence, Option C is correct, Each person receives an amount of $510.

Co-interior angles are (12x - 8)° and 104°.
To find:
The value of x.
Solution:
Sum of co-interior angles = 180°
12x° - 8° + 104° = 180°
12x° + 96° = 180°
Subtract 96° from both sides.
12x° + 96° - 96° = 180° - 96°
12x° = 184°
Divide by 12° on both sides.
x° = 7°
x = 7
The value of x is 7.

What is 5(x+20) = 7x+30?
Answer: 35
Step-by-step explanation:
Simplifying
5(x + 20) = 7x + 30
Reorder the terms:
5(20 + x) = 7x + 30
(20 * 5 + x * 5) = 7x + 30
(100 + 5x) = 7x + 30
Reorder the terms:
100 + 5x = 30 + 7x
Solving
100 + 5x = 30 + 7x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-7x' to each side of the equation.
100 + 5x + -7x = 30 + 7x + -7x
Combine like terms: 5x + -7x = -2x
100 + -2x = 30 + 7x + -7x
Combine like terms: 7x + -7x = 0
100 + -2x = 30 + 0
100 + -2x = 30
Add '-100' to each side of the equation.
100 + -100 + -2x = 30 + -100
Combine like terms: 100 + -100 = 0
0 + -2x = 30 + -100
-2x = 30 + -100
Combine like terms: 30 + -100 = -70
-2x = -70
Divide each side by '-2'.

how to compare box plots.
Box plots, or box-and-whisker plots, show data distribution through five main points: minimum, Q1, median, Q3, and maximum. A wider box indicates greater variability within the middle 50% of the data. To compare box plots, assess the spreads, medians, and potential outliers.
Explanation:A box plot, also known as a box-and-whisker plot, is a graphical representation of a data set that shows the distribution through five main data points: minimum value, first quartile (Q1), median, third quartile (Q3), and maximum value.
To construct a box plot, you typically start with a number line that has been properly scaled. Using a ruler for this purpose ensures accuracy.
The box in a box plot represents the middle 50 percent of the data, spanning from Q1 to Q3.
The 'whiskers' of the plot stretch from the box to the minimum and maximum values, indicating the entire range of the dataset.
Comparing the spread of the middle 50 percent of the data involves looking at the width of the box: a wider box suggests a greater spread, meaning the data is more varied within the interquartile range (IQR).
If you are using a graphing calculator, you can enter the data into a list and then select the box plot function to graphically display the data.
When comparing two or more box plots, look for differences in their central values (medians), spreads (IQRs), and potential outliers (which lie beyond 1.5 times the IQR from the quartiles).

A swimming pool sets a maximum number of swimmers that can be in the pool based on the number of lifeguards on duty.
The points on the following coordinate plane show the maximum number of swimmers that can be in the pool when 2, 4, and 5 lifeguards are on duty.
What is the maximum number of swimmers that can be in the pool with 3 lifeguards on duty?
Answer:120
Step-by-step explanation:
Final answer:
The maximum number of swimmers with 3 lifeguards on duty is 31/3.
Explanation:
To find the maximum number of swimmers with 3 lifeguards on duty, we need to look at the pattern shown by the points on the coordinate plane. From the given information, we know that with 2 lifeguards, the maximum number of swimmers is 8. And with 4 lifeguards, the maximum number of swimmers is 12. With 5 lifeguards, the maximum number of swimmers is 15. So, we can assume that the pattern follows a linear relationship. To find the maximum number of swimmers with 3 lifeguards, we can create a linear equation using the two known coordinates: (2, 8) and (5, 15). Using the slope-intercept form of a linear equation, y = mx + b, we can solve for b. The slope, m, is (15-8)/(5-2) = 7/3. Plugging in one of the coordinates, such as (2, 8), we can solve for b: 8 = (7/3)(2) + b. Solving for b, we get b = 8 - 14/3 = 10/3. So, the equation for the line is y = (7/3)x + 10/3. Plugging in x = 3, we can find the maximum number of swimmers: y = (7/3)(3) + 10/3 = 21/3 + 10/3 = 31/3. Therefore, the maximum number of swimmers with 3 lifeguards on duty is 31/3.
