Step-by-step explanation:
Although I don’t see that answer, with 53 children and 22 having a dog, 18 a cat, and 6 with both, you would think to subtract all three of those numbers with 53 to get the remaining with no dogs or cats, which results to 7
Ответ:
53-46=8
Therefore 8 students did not have a dog or a cat as a pet
Ответ:
first, we define the variables:
x: number of years after 1950
f (x): amount of vinyl sold.
then, with the variables defined, we have:
68594 vinyl records were sold in 1958 > f (8) = 68594
91299 vinyl records were sold in 1961 > f (11) = 91299
38720 vinyl records were sold in 1952 > f (2) = 38720
161743 vinyl records were sold in 1967 > f (17) = 161743
