Which function has a smaller minimum? What is that minimum value?
a.f(x) has the smaller minimum. The minimum is -1.
b.g(x) has the smaller minimum. The minimum is -1.
c.g(x) has the smaller minimum. The minimum is -3.
d.f(x) has the smaller minimum. The minimum is -3.
Answer:
c. g(x) has the smaller minimum. The minimum is -3.Step-by-step explanation:
Given functions
f(x) = (x - 1)^2 - 1 (graphed)and
g(x) = (x - 1)^2 - 3Comparing the vertex of the functions (the minimum), we see that:
f(x) has a vertex (1, -1)g(x) has a vertex (1, -3)Correct option is c)

A person has a 0.125 probability of getting the number 3 on a roll of an eight-sided die. If a person rolls the die 24 times, and gets a 3 on one-half of the rolls, what is the difference between the theoretical probability and the empirical probability of the person getting the number 3 on a roll? A. 0.125 B. 0.375 C. 0.5 D. 0.25
Answer:
0.375
Step-by-step explanation:
plato
The difference between the theoretical probability and the empirical probability is 0.375. So, option B is correct.
Probability:Important information:
The probability of getting the number 3 on a roll of an eight-sided die is 0.125.A person rolls the die 24 times and gets a 3 on one-half of the rolls.According to the given information, we have:
Theoretical probability = 0.125
Empirical probability = 0.5
The difference between the theoretical probability and the empirical probability of the person getting the number 3 on a roll is:
0.5 - 0.125 = 0.375
Hence, option B is correct.

Step-by-step explanation:
To answer this question, we have to keep in mind that when you are trying to figure out commission, you are taking away a percentage of the amount of money you are getting commission from. 10% of 3,000 is 300, as whenever you are taking 10% off of a number ending in a zero, you can take away that zero and that is 10% of the number. Since the goal is to earn $550 in commission, we simply subtract:
550 - 300 = 250
And $250 is our answer
Hope this helps :)
Answer:
250
Step-by-step explanation:
You get 10% of 3000 weekly which is 300, and you need 550, to find out how much more you need to earn we simply do 550-300=250.

In ΔQRS, the measure of ∠S=90°, QS = 11, SR = 60, and RQ = 61. What is the value of the sine of ∠Q to the nearest hundredth?
Answer:
0.98
Step-by-step explanation:
Below is a drawing of the triangle (drawing it out is an important step if you have trouble visualizing it).
Sine = opposite/hypotenuse, in this case, SR (60) is the opposite of angle Q and RQ (61) is the hypotenuse.
Sin(angle Q) = 60/61 = 0.98
