Two points on the graph of the linear function f are (0,3) and (3,9). Write a function g whose graph is a reflection in the x-axis of the graph of f
Answer:
199 if it's 7b^3 + 10
9271 if it's (7b)^3 + 10
Step-by-step explanation:
You just substitute the 3 in for d. If your expression was 7b^3 + 10, then only b is being raised to 3.
So 3^3 is 27, 27*7 is 189, 189+10 is 199.
If the expression was (7b)^3 + 10, then first you multiply 7 and 3 to get 21. Then you raise 21 to the power of 3, which is 9261. Then you add 10, which is 9271.
Answer:
(g + f)(x)
Step-by-step explanation:
the outputs of f(x) and g(x) will always have a sum of -1, which is h(x).
Answer:
Step-by-step explanation:
full=4.5 litres hint: 1 litre = 1000 ml
1/4full=?
1/4×4.5 →shows how many litres when a quarter full
= 1.125 litres
then multiply by 1000 to change to millilitres
=1.125×1000
= 1125 millilitres
Theoretical probability is based on the likelihood of events. It is the ratio of successes to the total number of cases. For flipping a coin once, the theoretical probability of it coming up heads is .5 and the probability of it coming up tails is .5 (assuming it will never land on its edge and stay that way).
The problem statement must mean “tossing a coin twice” or “tossing two coins.” Which did you do in your experiment??
So, let’s enumerate (list all the equally-likely cases) that can occur with two coins:
HH
HT
TH
TT
The probability (likelihood) of getting two heads is 1 in 4 (.25). The likelihood of getting two tails is also 1 in 4 (.25). However, the likelihood of getting one head and one tail (in any order) is 2 in 4 (.5).
Note: the probability of a coin flip does not depend on what has happened in previous flips; this is very important !!
An experiment may differ from this theoretical probability for a number of reasons: The coin might actually not be “fair,” you may have a flipping technique that favors one result (if so, you might want to become a gambler), …
Although experimental probability may differ from theoretical probability, it should not be too much different (note: we could express the probability that it will be 10% off, 20% off, etc.)
