Answer:
Yes
Step-by-step explanation:
For every x we have only one value of y, so this is a function. (Only One arrow from any value of X)
<span>1. </span><span>The ratio of a wire that is cut
in to 2 is 5:9
The longer piece was 25cm. Now, find the total length and the length of the
shorter wire.
=> 5 : 9 = x : 25
=> First, let’s convert it to fraction
=> <u>5 </u>=<u> 9
</u> x 25
=> 25 (5) = x (9)
=> 125 = 9x
=> 125 / 9 = 9x / 9
=> 13.9 = x
Thus the ratio is approximately 5 : 9 = 13.9 : 25 </span>
Answer:
X = 10 ( finding x - intercept/zero)
Step-by-step explanation:
y = - 800x + 8000
0 = - 800x + 8000
800x = 8000
x = 10
Answer
is (d)The vertex angle is one of two congruent angles of the triangle.
Step-by-step explanation
Explanation: Every triangle has 180 degrees. An isosceles triangle has one vertex angle and two congruent base angles. Thus, 65 is the base angle and 50 is the vertex angle.

Answer: D) 0.44</h3>
==========================================================
Explanation:
Add up all the frequencies that correspond to outcomes that are more than 3
So we'll add up the last three frequencies (since they correspond to outcomes of 4, 5 and 6 all of which are greater than 3) to get 20+30+38 = 88
We have 88 occurrences of rolling either a 4, a 5 or a 6. This is out of 200 rolls total.
The empirical (or experimental) probability of getting more than 3 on the die is 88/200 = 0.44
