Considering a six-sided spinner, it is found that the probability of spinning a 1 and tossing a head is of .
<h3>What is a probability?</h3>
A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.
In this problem:
- For the spinner, one is one out of six possible outcomes.
- For the coin, a head is one out of two possible outcomes.
Since the events are independent, the probability of spinning a 1 and tossing a head is given by:
.

Step-by-step explanation:
Answer: First option.
Step-by-step explanation:
You can use the inverse tangent function to find the value of the angle T:
You can identify in the figure that:
Then, knowing these values, you can substitute them into .
Therefore, you get that the value of the angle T rounded to the nearest degree is:
This matches with the first option.
Answer:
Step-by-step explanation:
There is a formula that can be used to find the x-value of the vertex of the parabola. This formula is
We have the function
From this function, we can find that
We can plug in our know values into the formula to get
Then we can plug in our x-value to find the y-value of the vertex
This means that the vertex would be
