Answer: y = -220
Step-by-step explanation:
y/11 ÷ 2= -10
To find the value of y
Rewrite the equation as y/11 ÷ 2/1 = -10
y/11 × 1/2 = - 10
y/22 = -10
Multiply each side by 22 to get the value of y
y= -10 × 22
y= -220
Check:
Slot the value of y into the equation
-220/11 ÷ 2 = -10
-20 ÷2 = -10

Answer:
a) Simple random sample
b) Random sample
c) None of them.
Step-by-step explanation:
a) This would be a simple random sample given that the dice roll is a random method to select the students and the probability of each outcome of the dice is 1/6.
b) This would be a random sample, given that the cards are shuffled, this is a random event. However, there's a condition on how to select the cards (The top ones are chosen) and therefore this can not be a simple random sample since not all cards have the same probability of being selected.
c) This is not a random sample since there is an specific condition on how to choose the students (by their age)
As you can see sphere's diameter = to a cube's edge...so the diameter of the sphere is also 12 cm. So its radius is 6 cm.
v= 4/3*πr³
v=4/3*3.14*6³
v=904.32
The volume of the sphere is about 904 cubic centimeters.
