Z=6. first, you want to get the z/2 by itself, so you subtract the 7 from both sides. you then get 3=z/2, and then multiply by two because multiplication is the opposite of division, so you can get the z alone. you then get z=6 because 3x2=6
Answer: The new ratio will be 1/4
Explanation: The initial ratio of losses to wins is 3 to 2. If we sum the numer of losses and wins 3 + 2 = 5 games, that means they loss 3 out of 5 games , and they win 2 out of 5 games.
So if they had won twice as many of the games, that is 2*2=4. And since the number of games is the same ( 5 ), then they would have won 4 games and loss only 1.
So the new ratio of losses to wins will be 1 to 4, or expressed in a fraction: 1/4
V= area of the base • height
V= pi• radius^2 •height
V= (3.14• 5^2) • 3
(3.14•25)•3
=235.5 units cubed

Answer: Values are unusual : $1774 and $606
Very unusual value = $606
Step-by-step explanation:
According to the empirical rule, when data is normally distributed (bell-shaped) then the values that are two standard deviations from the mean are unusual.
Given data: $1616 $1774 $1309 $606 $1470 $1542
Mean : and Standard deviation:
The range of the values lies within from mean .
The values are unusual (i.e. more than two standard deviations from the mean) = $1774 and $606
The range of the values lies within from mean .
The values are very unusual (i.e. more than three standard deviations from the mean) = $606
