Answer:
r=22.931374,−22.931374
Step-by-step explanation:
Let's solve your equation step-by-step.
1652/3.141593 = 3.141593r^2/3.141593
Step 1: Simplify both sides of the equation.
525.847932=r^2
Step 2: Subtract r^2 from both sides.
525.847932−r^2=r^2−r26
−r^2+525.847932=0
Step 3: Subtract 525.847932 from both sides.
−r^2+525.847932−525.847932=0−525.847932
−r^2=−525.847932
Step 4: Divide both sides by -1.
−r^2/−1 = −525.847932/−1
r^2=525.847932
Step 5: Take square root.
r=±√525.847932
r=22.931374,−22.931374
Answer:
r=22.931374,−22.931374
Answer: c. 1498
Step-by-step explanation:
Given : Preliminary estimates suggest that about 58% of students at a state university favor implementing an honor code.
i.e. p = 0.58
Significance level :
Critical value :
Margin of error =
The formula to find the sample size is given by :-
Hence, the minimum sample size needed = 1498
Answer: x = 1
Step-by-step explanation:
we have
x tetras
3 goldfish
5 platies.
the total number of fishh in the bowl is x + 3 + 5
The probability of removing a gold fish is equal to the number of gold fish divided by the total number of fish, this is:
p = 3/(x + 3 + 5) = 1/3
3 = (1/3)(x + 3 + 5) = x/3 + 1 + 5/3
9 = x + 3 + 5
x = 9 - 8 = 1
then wemust have that x = 1
because 1 + 3 + 5 = 9
and 3/9 = 1/3
