Answer:
C. In step 4, the (pie) should have canceled, making the correct answer 9 cm.
Step-by-step explanation:
Volume=576π cubic centimeters
Radius=8 cm
h=?
Her work:
Volume of a cyclinder=πr^2h
Step 1:
576π= π8^2h
Step 2:
576π = 64πh
Step 3:
576π / 64π = 64πh / 64π
Step 4:
h=9π cm
Correct workings:
Step 1:
576π= π8^2h
Step 2:
576π = 64πh
Step 3:
576π / 64π = 64πh / 64π
Step 4:
h= 9 centimeters
Her error is in step 4
C. In step 4, the (pie) should have canceled, making the correct answer 9 cm.
Evaluate the derivative of f(x) at x = 1. I'll use the limit definition:
Then using the point-slope formula, the equation of the tangent line to f(x) at the point (1, 5) is
y - 5 = 9 (x - 1)
y = 9x - 4
Answer: A) A boy is 19% more likely than a girl to own a dog than a cat or other animal.
Step-by-step explanation:
Here are the options:
A) A boy is 19% more likely than a girl to own a dog than a cat or other animal.
B) A boy is 33% more likely than a girl to own a dog than a cat or other animal.
C) A boy is 50% more likely than a girl to own a dog than a cat or other animal.
D) A boy is 52% more likely than a girl to own a dog than a cat or other animal.
Boy with a dog = 27
Total animals owned by boys = 27+15+10 = 52
Probability of owning a dog = 27/52 = 0.5192
Girl with dogs = 18
Total animals owned by girls = 18+25+12 = 55
Probability of owning a dog = 18/55 = 0.3273
Therefore, 0.5192 - 0.3273 = 0.1919 = 19.19%
Therefore, A) A boy is 19% more likely than a girl to own a dog than a cat or other animal.
I’m pretty sure it will be the last one f(x)=(3x+1)(2x-5).
Answer:
