Answer:
11.6
Step-by-step explanation:
F = k/ d^2
where k = proportionality constant
k = Fd^2
k = 5 * 9^2
k = 5*81 = 405
d = (K/F)^1/2
d = (405/3)^1/2
d = 11.62 =11.6
3x^2 + 180x - (3x^2 - 160x + 300) = profit
3x^2 + 180x - 3x^2 + 160x - 300 = profit
340x - 300 = profit
so if 150 televisions are sold...x = 150
340(150) - 300 =
50,700 <==
Answer:
Bob performed better in mathematics part of the SAT than the ACT
Step-by-step explanation:
We need to calculate the z-scores for both parts and compare them.
Z-score for the SAT is calculated using the formula:
where is the mean and is the standard deviation, and is the SAT test score.
We plug in these values to obtain:
to the nearest hundredth.
We use the same formula to calculate the z-score for the ACT too.
Where is the mean and is the standard deviation, and is the ACT test score.
We substitute the values to get:
to the nearest hundredth.
Since 1.29 > 1.25, Bob performed better in mathematics part of the SAT
