Answer:
Category A 3 1 8
Category B 3 2 1
Step-by-step explanation:
The relative frequency of the columns are:
Group 1 Group 2 Group 3
Category 1 4/11 1/4 11/19
Category 2 7/11 3/4 8/19.
What is the frequency?
The number of times a specific value appears in the data is its frequency (f). A variable's distribution is its frequency pattern, or the collection of all conceivable values and the frequencies corresponding to those values. Frequency tables or charts are used to represent frequency distributions.
Given table is
Group 1 Group 2 Group 3
Category 1 4 3 11
Category 2 7 9 8
The frequency of group 1 is (4+7) = 11
The frequency of group 2 is (3+9) = 12
The frequency of group 3 is (11+8) = 19.
The relative frequency is the ratio between the number of times an outcome value appears in the set of all outcomes and the total number of outcomes.
Group 1 Group 2 Group 3
Category 1 4/11 3/12 = 1/4 11/19
Category 2 7/11 9/12 = 3/4 8/19.

What is the value of x in this triangle? What is the value of each angle?
Answer:
x=17
Step-by-step explanation:
we know the 25 + 90 = 115 so we need the other one to make it 180 degrees.
180-115= 65
so we need 65 more degrees to get 180
now 3x + 11= 65 first step subtract 11 on both sides
you now get 3x = 54 then 2nd step is divide 3 on both sides
and now you get x=17 so
Answer:
Step-by-step explanation:
The entire value of the triangle is 180 degrees.
If you subtract 25 from 180 you are left with 155
Then Subtract 90 from 155 which will leave you with 65
Go on to subtract 11 from 65 having to be with 54 degrees left
Finally you will dived 54 by 3 and you are left with 18
3 x 18 = 54
54 + 11 = 65
Therefore x will equal to 65 degrees

A sports medicine major wanted to conduct an experiment to determine if there is a correlation between the members of the soccer team's leg strength and the time it takes for them to sprint 40 yards. He sets up the following test and records the data:
The time for 22 leg-press reps is 11.9 seconds.
Step-by-step explanation:The lines of best fit is the trend line of the dataset.
The equation of line of best fit is y = 0.120x + 9.274The time for 22 leg-press reps is 11.9 seconds(A) The equation of the line of best fitThe table is given as —
(x) : 12 32 7 26 28 15 1
(y) : 8.6 14.6 7.1 8.3 11.9 19.4 9.5
To determine the equation of line of best fit, we make use of a regression calculator.
Enter the above dataset in a regression calculator, the equation is: y = 0.120x + 9.274 (Approximated to Three Decimal Places / Rounded of to the Thousandths Place)
(B) The number of seconds for 22 leg-press repsThis means that x = 22.
So, we have:
y = 0.120 * 22 + 9.274
= 2.640 + 9.274
= 11.914
(Approximate to the nearest hundredths)
= 11.9
Hence, the time for 22 leg-press reps is 11.9 seconds.
Hope my answer helps you.

Sid has a baseball cap collection. 65% of his caps have sports team symbols. If 26 of the caps have the team symbols, how many total caps does Sid have?
39
40
73
91
B. 40
As we know Sid has 26 Caps
we also know that 26 is 65% of total
so let total caps = x
to calculate x
we know that percent = (Values*100)/total Values.......... i
and here Value = 26 caps
percentage = 65
So we have
65 = (26*100)/x---------------- (As we know that per = fraction*100)..... from i
65x= 2600x = 2600/65x=40 capsHence Answer is 40

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.

A theater sold 85% of the tickets for a
play. If 170 tickets were sold, how many
tickets were originally put up for sale?
Answer:
200 tickets.
Step-by-step explanation:
85% = 85/100 = 0.85
170/0.85 = 200
= 200
Check:
200*0.85 = 170
Answer: hope this helps ♡
200 tickets were originally put up for sale.
Step-by-step explanation:
85% = 170
(we divide 85 and 170 by 85)
1% = 2
(now multiply 1 and 2 by 100)
100% = 200
(double check: 85% from 200 → (85×200) ÷ 100 = 170 ✓)
Explain how the percent equation relates proportional quantities
the percent equation being
PART = PERCENT * WHOLE
Answer: This is the best I could find for you
Step-by-step explanation:
"When the ratio of part to whole is equal to the ratio of a percent to 100, shows a percent equal to an equivalent ratio, we call it a percent proportion. A percentage is a fraction expressed with 100 as the denominator. When two ratios are equal, they are said to be in proportion."
