The local amusement park was interested in the average wait time at their most popular roller coaster at the peak park time (2 p.m.). They selected 13 patrons and had them get in line between 2 and 3 p.m. Each was given a stopwatch to record the time they spent in line. The times recorded were as follows (in minutes).
118, 124, 108, 116, 99, 120, 148, 118, 119, 121, 45, 130, 118
What is the IQR?
a group of 43 children, with some adults, travelled by coach on a trip to a zoo
The total cost of the trip was £516
the entrance fee was £12.75 for each adult and£8.25 for each child
the cost of hiring the coach was £123
How many adults were in the group?
you must show your working
｡☆✼★ ━━━━━━━━━━━━━━ ☾
516 - 123 = 393
8.25 x 43 = 354.75
393 - 354.75 = 38.25
38.25 / 12.75 = 3
There were 3 adults

Answer:
3 adults
Step-by-step explanation:
(each child)£8.25×(total children)43=£354.75(total amount paid for children)
£354.75+£123=£477.75
£516-£477.75=£38.25
£38.25÷£12.75=3

Which of the following options best represent the equation of a function?
Select all that apply.
Options:
x + y = 16
x2 + y2 = 16
y = 2
x = 2
y = x2 + 2
y = |x + 2|
Please explain how you get your answer, ty
Answer:
y=2
x=2
y=x2+2
y= lx+2l
Step-by-step explanation:
This is because these are the simplest forms of the equation. seeing as a function is f(x) (which is the same as y) when an equation is equal to a single variable, it is "solved" for hat variable and therefore best represents the equation of the function :)
PLS I NEED HELP...THE PICTURES ARE IN ORDER (13 POINTS ) Question 1 Solve the following equation. Explain or show your reasoning. ---------------------------------------------------------------------------------------- Question 2 Solve the following equation. Explain or show your reasoning. ------------------------------------------------------------------------------------------ Clare was solving an equation, but when she checked her answer she saw her solution was incorrect. She knows she made a mistake, but she can’t find it. Where is Clare's mistake and what is the solution to the equation?
Answer:
1 . x = 9,
2 . n = 4,
3 . Clare made an error in the 2nd step; Correct answer is y = - 65 / 11
Step-by-step explanation:
1 .
[tex]2 * ( x + 5 ) = 3x + 1 - Apply Distributive Property,\\\\2x + 10 = 3x + 1 - Subtract 2x from Either Side,\\10 = x + 1 - Subtract 1 from Either Side,\\\\x = 9,\\Conclusion; x = 9[/tex]
2 .
[tex]3 * ( n + 2 ) = 9 * ( 6 - n ) - Apply Distributive Property,\\\\3n + 6 = 54 - 9n - Add ( 9n ) on Either Side,\\12n + 6 = 54 - Subtract 6 from Either Side,\\\\12n = 48 - Divide Either Side by 12,\\n = 4,\\\\Conclusion; n = 4[/tex]
3 . Clare made an error in the second step ( 72 + 24y = 4y - 5 - 9y ) and to derive the correct solution, see the following steps below;
[tex]12 * ( 5 + 2y ) = 4y - ( 5 - 9y ),\\60 + 24y = 4y - 5 + 9y,\\65 + 24y = 4y + 9y,\\65 + 24y = 13y,\\\\65 = - 11y,\\y = - 65 / 11\\\\Conclusion; y = - 65 / 11[/tex]

When dividing complex numbers, why do
you need to multiply the numerator and
denominator by the complex conjugate of the
denominator?
Answer:
Hope this helps..
Step-by-step explanation:
So when you need to divide one complex number by another, you multiply the numerator and denominator of the problem by the conjugate of the denominator. This step creates a real number in the denominator of the answer, which allows you to write the answer in the standard form of a complex number.
Answer:
You have to multiply by the complex conjugate because the denominator has to be a real number. By multiplying the complex conjugate you can transform the denominator in to a real number.

can 20 degrees 60 degrees and 100 degrees be a triangle
Answer: Yes
Step-by-step explanation: The area of a triangle equals 180°
100+60+20=180
Answer: Yes
Explanation: The sum of the measures of the angles is always 180°
This idea is known as the (Triangle Sum Theorem).
Since 20 + 60 + 100 is equal to 180, we know
that these measures can form a triangle.

Find the volume of the pyramid.
six copies of the sum of nine fifths and three.
Answer:
9/5+3/1
24/5 24/5 24/5 24/5 24/5 24/5
i think copies is a multiplication and sum is to add together so
6x(9/5+3)
9/5 is 1 whole and 4/5. 1 whole plus 3 wholes is 4 Wholes so it is 4 wholes and 4/5 which is 24/5.
6x24/5 is (6x24 is 144) so its 144/5 so its 28 wholes and 4/5.

Determine whether the forces in the pair are pulling at right angles to each other. For the values a = 1.6 and b = 5.8, which are legs of a right triangle, find c, the hypotenuse, to the nearest tenth
Answer:
Approximetly 6
Step-by-step explanation:
a^2 + b^2 = c^2
1.6^2 + 5.8^2 = c^2
2.56 + 33.64 = c^2
36.2 = c^2
c=6 (approximetly)

The annual rainfall for two cities, Albany and Zachary, in each of the years from 2002 to 2011 are shown in the tables. Annual Rainfall for Albany (in.) 23.36 18.51 28.54 22.36 30.50 24.74 11.93 15.34 18.07 15.98 Annual Rainfall for Zachary (in.) 27.27 20.11 31.14 25.88 32.97 25.03 18.55 23.91 22.75 19.73 Find the mean for the two cities' annual rainfalls. In which city does it rain more in a year, on average? Drag and drop the correct choices into the boxes to complete the statement. On average, Albany gets _ inches of rain per year and Zachary gets _ inches of rain per year. on average, which city rains more zachary or albany?
Answer:
On average, Albani gets 20.933 inches of rain per year.
On average, Zachary gets 24.734 inches of rain per year.
On average, Zachary gets more rain than Albani.
Step-by-step explanation:
Mean is given by:
[tex]Mean = \frac{Sum}{Total}[/tex]
For Albani :
Sum of total number of terms = 23.36+18.51+28.54+22.36+30.50+24.74+11.93+15.34+18.07+15.98
Sum of total number of terms = 209.33
Number of terms = 10
[tex]Mean=\frac{209.33}{10}\\\\Mean=20.933\\[/tex]
For Zachary :
Sum of total number of terms = 27.27+20.11+31.14+25.88+32.97+25.03+18.55+23.91+22.75+19.73
Sum of total number of terms = 247.34
Number of terms = 10
[tex]Mean=\frac{247.34}{10}\\Mean=24.734[/tex]

In right triangle ABC, ∠C is a right angle, m∠A=52∘, AC=10.01, and AB=c.

What is the measurement of AB?
In right triangle GHI, ∠H is a right angle, m∠I=42∘, and GH=11.
sin42∘≈0.67
cos42∘≈0.74
tan42∘≈0.90
What is the measurement of HI?
9514 1404 393
Answer:
AB = 16.25HI = 12.22Step-by-step explanation:
The mnemonic SOH CAH TOA reminds you of the relevant relationships.
__
1. Cos = Adjacent/Hypotenuse
cos(52°) = AC/AB
AB = AC/cos(52°) = 10.01/0.616
AB = 16.25
__
2. Tan = Opposite/Adjacent
tan(42°) = GH/HI = 11/HI
HI = 11/tan(42°) = 11/0.90
HI ≈ 12.22

Answer: [tex]\dfrac{1}{8}[/tex]
Step-by-step explanation:
Formula : Probability = [tex]\dfrac{\text{favorable outcomes}}{\text{total outcomes}}[/tex]
Given , Sam has 4 cards numbered 2,3,5, and 7.
His friend has 4 cards numbered 1,2,6 and 7.
If they both draw one card and put that on table , then the possible combinations of cards would be (2,1) , (2,2), .... (7,6), (7,7).
i.e. Number of possible outcomes would be (S) 4 x 4 = 16
Favorable outcomes that they will choose same number (F) = (2,2) , (7,7)
Now , the probability that they will both choose the same number would be :
[tex]\dfrac{F}{S}=\dfrac{2}{16}=\dfrac{1}{8}[/tex]
Hence, the required probability = [tex]\dfrac{1}{8}[/tex]
Write the first six terms of the sequence.
a1 = 4, an = An-1 +5
Answer:
{4, 9, 14, 19, 24}
Step-by-step explanation:
Best to use the notation a(1) = 4, a(n) = a(n-1) + 5.
a(1) = 4 (given)
a(2) = 9 (here we found a(2) by adding the common difference, 5, to a(1)
a(3) = 14
a(4) = 19
a(5) = 24
