Answer:
girls = 90
boys = 125
adults = 20
Detailed explanation:
Total attendees at the summer camp = 235
Let
girls = x
boys = x + 35
adults = x - 70
Total attendees = girls + boys + adults
235 = x + (x + 35) + (x - 70)
235 = x + x + 35 + x - 70
235 = 3x - 35
Add 35 to each side
235 + 35 = 3x
270 = 3x
Divide both sides by 3
x = 270/3
= 90
x = 90
girls = x = 90
boys = x + 35
= 90 + 35
= 125
adults = x - 70
= 90 - 70
= 20
Total = 90 + 125 + 20
= 235
Answer:
a. the class with the highest number of observations.
Step-by-step explanation:
The mode refers to the value within a dataset that appears most frequently. This indicates that it occurs with greater frequency than other values.
In a histogram, the modal class denotes the category that has the most observations, demonstrating that the variables in that category have a higher occurrence than those in others. Consequently, the answer sought is option a.
Answer:
x = -4/45
Step-by-step breakdown:
180x=2(30÷3)+17-5•11+2÷1
We first need to simplify the right side. The initial step involves the parentheses
180x=2(10)+17-5•11+2÷1
Next, we multiply and divide, proceeding from left to right after the equals sign.
180x=20+17-5•11+2÷1
180x=20+17-55+2÷1
180x=20+17-55+2
Next, we add and subtract, moving from left to right in relation to the equals sign.
180x=37-55+2
180x =-18+2
180x = -16
Then divide each side by 180
180x/180 = -16/180
x = -4/45
