Answer:
a, the first option
Step-by-step explanation:
You solve the inequality equation just like any other equations. The only difference is that you gotta flip the sign whenever you multiply or divide by a negative number.
The result is p>32, which is an open-circle at 32 that points toward all values greater than 32
Answer: A
Step-by-step explanation: once you line the numbers up in order from least the greatest, the two middle numbers will be 12. Add 12 + 12 and you get 24. Then divide it by 2 and get 12. That is your median. Your 1st quartile will be 10. Your second quartile will be 15. Your minimum number is 4 and your maximum number is 18.
Answer:
48
Step-by-step explanation:
The fraction who picked apples is the rest of the students:
1 - 5/8 = 3/8
of them.
So the number who picked apples relative to the number who picked bananas is ...
apples/bananas = (3/8)/(5/8) = 3/5
Multiplying this by the number who picked bananas gives the number who picked apples:
apples = bananas · 3/5 = 80·3/5 = 48
48 students picked apples.
____
<em>Alternate solution</em>
Let "a" represent the number who picked apples. The ratio of banana choosers to the total is 5/8, and there were 80 who chose bananas. That gives rise to the equation ...
80/(80 +a) = 5/8
640 = 400 +5a . . . . . . multiply by 8(80+a) and simplify
240 = 5a . . . . . . . . . . . subtract 400
240/5 = a = 48 . . . . . . divide by 5
48 students picked apples.

Not enough information
Step-by-step explanation:
Without being given the age for at least one of the people at any given time we cannot come to a solid answer
Answer:
m(arc CD) = 122°
Step-by-step explanation:
Since, measure of an arc = 2 × (Angle subtended by the arc at the circumference of the circle)
m(arc CD) = 2[m(∠CBD)]
By triangle sum theorem in ΔBCD,
m∠CBD + m∠BDC + m∠DCB = 180°
m∠CBD + 49° + 70° = 180°
m∠CBD = 180° - 119°
m∠CBD = 61°
Therefore, m(arc CD) = 2 × 61°
m(arc CD) = 122°
