Answers
Question:
The scatter plot shows the maximum noise level when different numbers of people are in a stadium. The linear model is given by the equation y=1.5x + 22.7 where y represents maximum noise level and x represents the number of people, in thousands, in the stadium.
A sports announcer states that there are 65,000 fans in the stadium. Estimate the maximum noise level. Is this estimate reasonable? Explain your reasoning.
Answer:
[tex]y = 97522.7[/tex]
Step-by-step explanation:
Given
[tex]y = 1.5x + 22.7[/tex]
[tex]x = 65000[/tex]
Required
Find y
Substitute 65000 for x in the given equation
[tex]y = 1.5 * 65000 + 22.7[/tex]
[tex]y = 97500 + 22.7[/tex]
[tex]y = 97522.7[/tex]
It is reasonable because as the population increases, the noise level also increases

double the sum of a number and 3
Answers
Hey there!
Your answer is 2(n + 3)
"Double" represents multiplying by two. Also, "sum of a number and 3" represents the addition of 3 and a number, so we could put "n + 3". Since we are doubling the sum, it would be "2(n + 3)"

Step-by-step explanation:
Both numbers are easily simplified by 3 and that's as far as it can go because 11 is a prime number
9÷3=3
33÷3=11
3/11=9/33
Answer:
3/11
Step-by-step explanation:
Find the GCD (or HCF) of numerator and denominator
GCD of 9 and 33 is 3
Divide both the numerator and denominator by the GCD

One grocery clerk can stock a shelf in 25 min. A second clerk requires 45 min to stock the same shelf. How long would it take to stock the shelf if the two clerks worked together?
Answers
Answer:
clerk A and clerk B can simultaneously stock a shelf in 180/13 minutes
Step-by-step explanation:
Let the first clerk be A and the second clerk be B
A can stock a shelf in 20 min
B can stock a shelf in 45 min
Consider the complete work to be W
A’s rate of stocking = per minute
B’s rate of stocking = per minute
When, A and B work simultaneously, rate of work done =
Total work done simulatenously = 180/13
Therefore, clerk A and clerk B can simultaneously stock a shelf in 180/13 minutes
Answer:
Step-by-step explanation:
The rate of each clerk is 1/25 and 1/45 respectively so together they can stock the shelf
t/25+t/45=1 (the least common multiple of 25 and 45 is 225)
t/25(9/9)+t/45(5/5)=1
(9t+5t)/225=1
9t+5t=225
14t=225
t=225/14 min
t=16 minutes (rounded to nearest minute)
( or 16 minutes and about four seconds :) )

Answer:
1/5[8x³ –7x² –21x + 18]
Step-by-step explanation:
Let the polynomial be:
ax³ + bx² + cx + d
Where:
a => is the coefficient of x³
b => is the coefficient of x²
c => is the coefficient of x
d => is the constant term.
From the question given above,
Coefficient of x² (b) = a – 3 ..... (1)
Coefficient of x (c) = 3b ...... (2)
Constant term (d) = 2 + a ..... (3)
Sum of coefficient (a + b + c) = –4
a + b + c = –4
b = a – 3
c = 3b = 3(a – 3)
a + b + c = –4
a + (a – 3) + 3(a – 3) = –4
a + a – 3 + 3a – 9 = –4
Collect like terms
a + a + 3a = –4 + 3 + 9
5a = 8
Divide both side by 5
a = 8/5
Substitute the value of a into equation (1)
b = a – 3
a = 8/5
b = 8/5 – 3
b = (8 – 15)/5
b = –7/5
Substitute the value of b into equation (2)
c = 3b
b = –7/5
c = 3(–7/5)
c = –21/5
Substitute the value of a into equation (3)
d = 2 + a
a = 8/5
d = 2 + 8/5
d = (10 + 8)/5
d = 18/5
SUMMARY:
a = 8/5
b = –7/5
c = –21/5
d = 18/5
Thus, the polynomial:
ax³ + bx² + cx + d
8/5x³ + (–7/5)x² + (–21/5)x + 18/5
8/5x³ –7/5x² –21/5x + 18/5
1/5[8x³ –7x² –21x + 18]

In circle O, central angle COD has a measure of 48. Find the measure of arc BC. In your final answer, include all your work
Answers
Answer:
Measure of arc BC = 132°
Step-by-step explanation:
Measure of the central angle COD = 48°
Therefore, measure of arc AB = 48°
Since, segment AC is a diameter and central angle for a diameter is 180°.
Measure of major arc ABC = 180°
measure of arc AB + measure of arc BC = 180°
48° + measure of arc BC = 180°
Measure of arc BC = 180° - 48°
= 132°
