A. The range is 31.
B. The mode is 78
C. The median is 51
D. The mean is 52.
Answers
Answer:
D. The mean is 52.
Step-by-step explanation:
In order to find the mean, you add up all of the numbers and then divide that answer by how many numbers there are.
43+50+60+36+47+52+78=416
416/8=52
Answer:
D. The mean is 52.
Step-by-step explanation:
Add all numbers in the set:
36+47+50+50+52+60+78= 416
Now, divide the sum by how many numbers are in the set; in this case, there are 8 numbers so:
416÷ 8= 52

Answer:
Six / 6
Step-by-step explanation:
Fifteen less than 4 times a number is 9, meaning we have to find the number.
Let the required number be x
4 times the number = 4x
15 less than 4 times the number = 4x-15
⇒ 4x – 15 = 9
⇒ 4x = 9 + 15
⇒ 4x = 24
⇒ x = 6
meaning the number is 6.

Use what you've learned to write the equation of a parabola that is narrower than y = x ,

opens downward, and has vertex (2, – 4).
Answers
Answer:
y = -a(x – 2)² – 4
a > 1
Example:
y = -2(x – 2)² – 4
Step-by-step explanation:
y = a(x – h)² + k
____________________
vetex: (h, k)
a: vertical reflection or stretch/compression
__________________________________
If it opens downward, has a vertex of (2, -4) and is narrower than y = x².
Then x² will have a negative coefficient of less than -1 and the input of x will be subtracted by the x value of the vertex which is 2, and the output will be added by the y value of the vertex which is -4.
Therefore y = -a(x – 2)² – 4 where a > 1

If gas costs $3.15 per gallon, how many whole gallons of gas could you buy with $27.00?
(Make sure to answer with a whole number.) just explain it
Answers
Answer: 8 whole gallons.
Step-by-step explanation: If you have only $27.00 and you need to buy gas, but each gallon is $3.15, then you just need to divide your total amount ($27.00) by your cost per gallon ($3.15), and you will get about 8.6 gallons, however this question asks for how many WHOLE gallons you can get, so all you need to do is round down to fit your budget, leaving money for only 8 whole gallons.
WORK: ($27.00) / ($3.15) = 8.6 gallons
Given: Circle k(O), diameter US , m RU=50°, m UT=30° Find: m∠RUS, m∠UST
**WILL GIVE BRANLIEST**
Answers
Applying the inscribed angle theorem, the missing angles are:
m∠RUS = 65°m∠UST = 15°What is the Inscribed Angles Theorem?Based on the inscribed angle theorem, we have the following relationships:
Inscribed angle = 1/2(measure of intercepted arc)Central angle = measure of intercepted arc.Given the following:
m(RU) = 50°m(UT) = 30°Find m(RS):
m(RS) = 180 - m(RU)
Substitute
m(RS) = 180 - 50
m(RS) = 130°
Find m∠RUS:
m∠RUS = 1/2(m(RS) [inscribed angle theorem]
Substitute
m∠RUS = 1/2(130)
m∠RUS = 65°
Find m∠UST:
m∠UST = 1/2(m(UT))
Substitute
m∠UST = 1/2(30)
m∠UST = 15°
