A card was selected at random from a standard deck of cards. The suit of the card was recorded, and then the card was put back in the deck. The table shows the results after 40 trials.
What is the relative frequency of selecting a club?
17%
20%
25%
30%
PLEASE ANSWER QUICKLY
Answer:
25%
Step-by-step explanation:
This is the answer because there are 4 different types of cards that can be chosen, the amount of trials is insignificant in this question. Since there are 4 types, there is a 1/4 chance of picking a club, another way to put this is 25%, thus giving your answer!

The amount that two groups of students spent on snacks in one day is shown in the dot plots below.
Group A
A dot plot titled Group A. A number line going from 0 to 5 labeled Amount in Dollars. There are 0 dots above 0, 5 above 1, 4 above 2, 1 above 3, and 0 above 4 and 5.
Group B
A dot plot titled Group B. A number line going from 0 to 5 labeled Amount in Dollars. There are 0 dots above 0, 3 above 1, 2 above 2, 4 above 3, 0 above 4, and 1 above 5.
Which statements about the measures of center are true? Select three choices.
The mean for Group A is less than the mean for Group B.
The median for Group A is less than the median for Group B.
The mode for Group A is less than the mode for Group B.
The median for Group A is 2.
The median for Group B is 3.
Answer:
1. The mean for Group A is less than the mean for Group B
2. The median for Group A is less than the median for Group B.
3. The mode for Group A is less than the mode for Group B.
Step-by-step explanation:
1. To find the mean for Group A, you use the formula: Total sum/Total frequency.
To find the total sum, you multiply the frequency(how many times the given number is repeated) with the given numbers.
0 × 0 = 0
1 × 5 = 5
2 × 4 = 8
3 × 1 = 3
4 × 0 = 0
5 × 0 = 0
Total Sum: 5 + 8 + 3 = 16
Total frequency: 5 + 4+ 1 = 10
[tex]\frac{16}{10}[/tex] = 1.6
To find the mean for Group B, you repeat everything above.
0 × 0 = 0
1 × 3 = 3
2 × 2 = 4
3 × 4 = 12
4 × 0 = 0
5 × 1 = 5
Total Sum: 3 + 4 + 12 + 5 = 24
Total frequency: 3 + 2 + 4 + 1 = 10
[tex]\frac{24}{10}[/tex] = 2.4
2. I can't explain it but I'm certain that it is correct.
3. The most repeated number for Group A is 1, it is repeated 5 times, while the most repeated number in Group B is 3, it is repeated 4 times.

Which number line shows the graph of x≤6
?
Answer:
C
Step-by-step explanation:
There is a line under the "<" sign which means that "x" can be equal to 6. The arrow going left shows that x is less than 6 and the dot being shaded mean that 6 can be an answer so the number line C is the answer. Hope this helped:)
The required number line that shows the expression x ≤ 6 is figure C. Option C is correct.
Inequality can be defined as the relation of the equation containing the symbol of ( ≤, ≥, <, >) instead of the equal sign in an equation.
What is a number line?A number line is defined as the number marked on the line calibrated into an equal number of units. For example -1, 0, 1, and so on.
Here,
The expression x ≤ 6 implies that the domain of the x is a set of a real number less than and equal to 6, so all values represented on the number line below and equal to 6 is bold dark.
Thus, the required number line that shows the expression x ≤ 6 figures C. Option C is correct.

Trend lines
Help will be greatly appreciated!
The manager of fast food restaurant collected data to study the relationship between the number of employees working registers and the amount of time customers waited in line to order. He made a scatter plot of the data and credited a trend line with the equation y= -70x+300, where y is the total amount of time waited in seconds and x is the number of employees working registers.
1. Did the scatter plot of data positive, negative, or no association? Explain your reasoning.
2. Maria went to the restaurant and waited 90 seconds to place her order. Use the trend line equation to predict how many employees were working.
3. Kiara went to the restaurant and waited 3.5 minutes. Use the trend line to predict how many employees are working.
4. Ashton walked into the restaurant and 4 employees are working registers. Use the trend line equation to predict how long he will wait to place his order.
Answer: the slope is 3 and the intercept is 0.
Step-by-step explanation:The trend line for the bivariate data shown in the scatter plot has the equation Y=3x
To determine the slope for a straight line (y=a*x+b)we take the two points that are shown and apply the following equation:
To determine the intercept we put the slope which we calculated into the equation for the point (2,6) and clear for b
