Which of these expressions would be the best estimate of the quotient 15 1/2 ÷ 3 2/3?
A. 15÷3
B. 15÷4
C. 16÷3
D. 16÷4
Answer:
D
Step-by-step explanation:
Because 15 1/2 ÷ 3 2/3 equals 4.22727272727 and 15 divided by 3 is 5, 15 divided b 4 = 3.75 16 divided by 3 is 5.33333333333 and 16 divided by 4 equals 4 so thats the closest answer

A politician running for office called random phone numbers to see what proportion of the vote he could anticipate getting. From his sample of responses, he estimated that he would get 47% ± 4% of the vote with 90% confidence. When calling, some people refused to answer his question about whether they plan to vote for him, some people never answered the phone (even after repeated calls), some people do not have landlines (or are unlisted), some people may not have told the truth since the politician himself talked to them, and some were not sure yet whom they plan to vote for.
What biases are present that cannot be accounted for through margin of error? Check all that apply.
voluntary response bias
undercoverage
response bias
nonresponse bias
sampling variation
Answer:
It’s B, C, D

Answer:
C $126,720
Step-by-step explanation:
First hour: 1280 tickets
Second hour: 20% more than 1280 tickets
20% of 1280 = 0.2 * 1280 = 256
1280 + 256 = 1536
Second hour: 1536 tickets
First & second hour tickets:
1280 + 1536 = 2816
Total sales:
2816 * $45 = $126,720
Answer: C $126,720

The time between arrivals of small aircraft at a county airport is exponentially distributed with a mean of one hour. (a) What is the probability that more than three aircraft arrive within an hour? (b) If 30 separate one-hour intervals are chosen, what is the probability that no interval contains more than three arrivals?(c) Determine the length of an interval of time (in hours) such that the probability that no arrivals occur during the interval is 0.10.
Answer:
(a) The probability that more than three arrive in one hour is approximately 0.018988
(b) The probability that no interval contains more than 3 arrivals in 30 separate one-hour intervals is approximately 0.56264
(c) The length of time such that the probability of no arrival is 0.1 is approximately 2.30259 hours
Step-by-step explanation:
The distribution of the arrival time of a small aircraft = Exponential distribution
The mean arrival time, μ = 1 hour
The pdf of a exponential distribution, f(x) = λ·e^(-λ·x)
The mean, μ = 1/λ
∴ 1 = 1/λ
λ = 1 hour
∴ For the exponential distribution, f(x) = 1·e^(-x)
(a) The Poisson probability is given as follows;
[tex]P(X = k) = \dfrac{\lambda^k \times e^{-k}}{k!}[/tex]
The probability for more than 3 is given as follows;
[tex]P(X > 3) = 1 - \dfrac{1^0 \times e^{-1}}{0!} - \dfrac{1^1 \times e^{-1}}{1!} - \dfrac{1^2 \times e^{-1}}{2!} - \dfrac{1^3 \times e^{-1}}{3!} \approx 0.018988[/tex]
(b) P(X ≤ 3) for 30 1 hour intervals = P(X ≤ 3)³⁰ = (1 - 0.018988)³⁰ ≈ 0.56264
(c) When the probability that no arrival occurs is 0.1, we have;
0.1 P(X > x) = f(x) = 1·e^(-x) = e^(-x)
-x·ln(e) = ln(0.1)
∴ x = -㏑(0.1) ≈ 2.30259
The length of time such that the probability that no arrival occur during the interval is 0.1, x ≈ 2.30259 hours.

Answer:
x=6
Step-by-step explanation:
(1/3x+2=4)x3
x+6=12
x=12-6
x=6
Answer: 6
Step-by-step explanation:
1/3x + 2 = 4
1/3x = 2 (subtracted 2 from both sides to get rid of the 2)
x = 6 (multiplied both sides by 3 to get rid of the coefficient)
What are the coordinates of the point on the directed line segment from (−1,−8) to (5,−2) that partitions the segment into a ratio of 1 to 2?
I need help quick
Answer:
There are two possible options: [tex]P(x,y) = (1, -6)[/tex] or [tex]P(x,y) = (3, -4)[/tex].
Step-by-step explanation:
There are two possible options depending on what the point of origin is. Vectorially speaking, we can determine the coordinates of the point that partitions the segment is described below:
[tex]P(x,y) = A(x,y) + r\cdot [B(x,y) - A(x,y)][/tex] (1)
Where:
[tex]A(x,y)[/tex] - Point of origin.
[tex]B(x,y)[/tex] - Point of destination.
[tex]r[/tex] - Partition factor.
Option 1: [tex]A(x,y) = (-1, -8)[/tex], [tex]B(x,y) = (5, -2)[/tex], [tex]r = \frac{1}{3}[/tex]
[tex]P(x,y) = (-1, - 8) + \frac{1}{3}\cdot [(5,-2)-(-1,-8)][/tex]
[tex]P(x,y) = (-1, -8) + \frac{1}{3}\cdot (6,6)[/tex]
[tex]P(x,y) = (-1,-8) + (2,2)[/tex]
[tex]P(x,y) = (1, -6)[/tex]
Option 2: [tex]A(x,y) = (5,-2)[/tex], [tex]B(x,y) = (-1,-8)[/tex], [tex]r = \frac{1}{3}[/tex]
[tex]P(x,y) = (5,-2) + \frac{1}{3}\cdot [(-1,-8)-(5,-2)][/tex]
[tex]P(x,y) = (5,-2) +\frac{1}{3}\cdot (-6,-6)[/tex]
[tex]P(x,y) = (5,-2) +(-2,-2)[/tex]
[tex]P(x,y) = (3, -4)[/tex]
There are two possible options: [tex]P(x,y) = (1, -6)[/tex] or [tex]P(x,y) = (3, -4)[/tex].

QUESTION 10 of 10: Your plan for your T-shirt business calls for you to be able to produce 60,000 screen printed shirts in a month. If each
screen press can handle 500 shirts per day, about how many presses do you need?
a) 2
b) 3
c) 4
od) 5
ОООО
There are 4 presses we need.
What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
Your plan for your T-shirt business calls for you to be able to produce 60,000 screen printed shirts in a month.
And, Each screen press can handle 500 shirts per day.
Now,
Since, In a month there are 30 days.
And, Your plan for your T-shirt business calls for you to be able to produce 60,000 screen printed shirts in a month.
Hence, Number of shirts need to press per day = 60,000 / 30
= 2,000
Since, Each screen press can handle 500 shirts per day.
Hence, Number of press for 2,000 shirts = 2,000 / 500
= 4
Thus, There are 4 presses we need.

A new watch costs $38.85, and a new bracelet costs $22.38. If Maddy buys both, how much does she spend? no photo links cus its a write prob
Answer:
$61.23
Step-by-step explanation:
Find how much she will spend by adding the costs together
38.85 + 22.38
= 61.23
So, if she buys both, she will spend $61.23
Answer:
[tex] \bf \huge 61.25[/tex]
Step-by-step explanation:
Given that :A new watch costs $38.85a new bracelet costs $22.38to find :If Maddy buys both, how much does she spend ?explanation :we have,
watch cost = $ 38•85bracelet cost = $ 22•38finding the cost of how much maddy spend for watch and bracelet
⟼ watch cost = $ 38•85
⟼ bracelet cost = $ 22•38
⟼ for finding the both cost add watch and bracelet cost
⟼ $ 38•85 + 22•38
⟼ $ 61•23
∴ maddy cost $ 61•23 for buys both.
Un turista pagó un total de 180 dólares en un hotel. La cuenta incluye el costo de tres noches de hospedaje y 75 dólares de alimentación.
El siguiente procedimiento permite determinar cuántos dólares pagó el turista, por cada noche de hospedaje. 3X+ 75 = 180
3X +75 -75 = 180 – 75
3X = 105
¿Cuál de los siguientes pasos completa correctamente el procedimiento?Single choice.
(10 Points)
3X – 3 = 105 – 3
3X + 3 = 105 + 3
3.(3X) = (3).105
3X/3 = 105/3
