Answer:
55% of the people surveyed were satisfied with the car
Step-by-step explanation:
The proportion of people surveyed who were satisfied with the car is the number of people who said they would buy that type of car again divided by the total number of people survied.
The percentage is the proportion multiplied by 100.
We have that:
2,300 people surveyed
1,265 said they would buy that type of car again.
1265/2300 = 0.55
0.55*100 = 55%
55% of the people surveyed were satisfied with the car
Answer:
1) 2/7; 43; 3/7
2) C
3) 30; 30; 10; is not; 10; is not
Step-by-step explanation:
1) y + 4/7 = 6/7
y = 6/7 - 4/7
y = 2/7
17 + b = 60
b = 60 - 17
b = 43
6/7 = m + 3/7
m = 6/7 - 3/7
m = 3/7
2) 11.5 - x = 5.25
x = 11.5 - 5.25
x = 6.25
3) he can substitute 30 for t.
He can then multiply ⅓ by 30 to get a product of 10 (⅓ × 30 = 10).
Since 15 is not equal to 10, Harry's solution is not correct
Step-by-step explanation:
a. y=mx+c
m = rise/run
3/2=m
1.5=m
b. y=1.5x+3
c. y int. x=0 x int. y=0
y=1.5(0)+3 0= 1.5x+3
y= 3 -3=1.5×
1.5x/1.5=-3/1.5
x= 2
d. y-y1 =m(x-x1)
y-3=1.5(×-2)
y-3 =1.5x-3
y-3+3=1.5x-3+3
y=1.5x +0
y int =3 x int =2
