Answer: The first box
Step-by-step explanation:
V represents volume and r represents radius
So V(r) represents the volume of the basketball with respect to radius
In a survey with 60 people, each people would get 1/60th of the chart which has 360 degrees, so everyone would get 360/60=6 degrees
and 13 people would get 13*6=78 degrees!
The main purpose is to finda formula that fits the relationship between the two variables the best. Like the line of best fit on a scatter plot.
Answer:
19. 3x+5/2x+7 =5
or, 3x+5=5×(2x + 7)
or, 3x + 5 = 10x + 35
or, 5 - 35 = 10x - 3x
or, -30 = 7x
or, -30/7 = x
21. let x be the other number
we know,
or, x × 1/7 =2
or, x/7 =2
or, x = 14
therefore, the other number is 14.
16 -> 17 : +1
17 -> y : +2
y -> 22 : +3
17+2=19
19+3=22
y=19
