Answer:
Step-by-step explanation:
<span>The <u>correct answers</u> are:
A ray is a bisector of an angle if and only if it splits the angle into two angles; and
A) I can afford to buy a ticket.
Explanation<span>:
For the first question, the first three answers are very specific and true:
A whole number is odd if it is not divisible by 2, and a number is not divisible by 2 if it is odd;
an angle is straight if its measure is 180 degrees, and the measure of an angle is 180 degrees if it is a straight angle;
a whole number is even if it is divisible by 2, and a number is divisible by 2 if it is even.
However, with the fourth choice, we are missing a key word in the definition. A ray is a bisector of an angle if and only if it splits the angle into two <u>CONGRUENT</u> angles. It is not just a ray that cuts an angle into two pieces, the pieces must be equal.
For the second question, the Law of Detachment says if our conditional "if p, then q" is true and p is true, then q must also be true.
For this question, "I can go to the concert if I can afford to buy a ticket" is true as well as "I can go to the concert." This means "I can afford to buy a ticket" must be true as well.</span></span>
<span>1. The highest speed is 39 mph.
2. 50 percent of the students drove between 15 and 28 mph.
3. A box and whisker plot shows the median speed.
4. 20 is the median speed for this data set.
5. A box and whisker plot is helpful in plotting variations in data and making it easy to read. It is also useful when there are multiple sets of data.</span>
Answer:
The desired distance is 15 units.
Step-by-step explanation:
Note how x increases from 1 to 10 and y from 0 to 12 at the same time.
Using the Pythagorean Theorem, we find that the distance between the two points is the length of the hypotenuse, which is
d = √[ (10 - 1)^2 + (12 - 0)^2 ], or d = √ [81 + 144] = 225 = +15
The desired distance is 15 units.
