The circle is centered at point C. Line segment PQ is parallel to SR.
What is the measure of angle QPS?
Answer:
m∠QPS = 112
Step-by-step explanation:
Shape PQRS is a cyclic quadrilateral as every vertex of the quadrilateral touches the circumference of the circle.
The opposite angles in a cyclic quadrilateral add up to 180°.
⇒ m∠QPS + m∠QRS = 180°
⇒ m∠QPS + 68° = 180°
⇒ m∠QPS = 180° - 68°
⇒ m∠QPS = 112°

what is the equation of the line that passes through the point (-3,7) and has a slope of 1/3
Answer:
y = 1/3 x + 8.
or in standard form:
x - 3y = -24.
Step-by-step explanation:
To answer this we use the point-slope form of the equation of a line:
y - y1 = m(x - x1)
Here we have m = 1/3 and (x1, y1) = (-3, 7), so:
y - 7 = 1/3(x - (-3))
y - 7 = 1/3( x + 3)
y - 7 = 1/3 x + 1
y = 1/3 x + 8 .
This is the slope-intercept form of the equation.
Converting to standard form, we first multiply by 3:-
3y = x + 24
- x + 3y = 24
x - 3y = -24.
Please evaluate this equation, and explain how you got the answer.
Answer:
3 = f
Step-by-step explanation:
3(6 - f) - 4 = 3f - 4
Distribute within Parenthesis
18 - 3f - 4 = 3f - 4
Combine like terms
14 - 3f = 3f - 4
Add 3f on both sides of the equation
14 = 6f - 4
Add 4 on both sides of the equation
18 = 6f
Divide by 6 on both sides of the equaiton to get your answer of
3 = f

Write down in terms of n, an expression for the nth term
of the following sequences:
a) 2 5 8 11 14
b) 9 11 13 15 17
Answer:
a) [tex]a_n=3n-1[/tex]
b) [tex]a_n=2n+7[/tex]
Step-by-step explanation:
a) From inspection, we can see that this is an arithmetic sequence as the difference between each term is the same:
14 - 11 = 3
11 - 8 = 3
8 - 5 = 3
5 - 2 = 3
(so the common difference = 3)
General equation of arithmetic sequence: [tex]a_n=a+(n-1)d[/tex]
(where [tex]a[/tex] is the first term and [tex]d[/tex] is the common difference between terms)
Given:
[tex]a=2[/tex][tex]d=3[/tex][tex]\implies a_n=2+(n-1)3[/tex]
[tex]\implies a_n=2+3n-3[/tex]
[tex]\implies a_n=3n-1[/tex]
b) From inspection, we can see that this is an arithmetic sequence as the difference between each term is the same:
17 - 15 = 2
15 - 13 = 2
13 - 11 = 2
11 - 9 = 2
(so the common difference = 2)
General equation of arithmetic sequence: [tex]a_n=a+(n-1)d[/tex]
(where [tex]a[/tex] is the first term and [tex]d[/tex] is the common difference between terms)
Given:
[tex]a=9[/tex][tex]d=2[/tex][tex]\implies a_n=9+(n-1)2[/tex]
[tex]\implies a_n=9+2n-2[/tex]
[tex]\implies a_n=2n+7[/tex]

Rebecca ran the width of a field, a distance of 60 yards. Then she ran the length of the field,
a distance of 80 yards. Finally, she ran diagonally across it to get back to her starting point.
How far did Rebecca run?
Answer:
170 yards
Step-by-step explanation:
First off we know that Rebecca ran 60 yards at first. Then she ran another distance of 80 yards. She then ran diagonally across to get back. If she ran diagonally back that means would have run 30 yards back which is half of the first distance she ran.
(representation of how she ran)
1st: Up along the width |
2nd: sideways along the length ----
3rd: diagonally back to the starting point /
This would form a triangle. The first distance he ran would be halved to show the amount that Rebecca ran diagonally, we will represent this with x.
Equation representation:
60 + 80 = 140 yards
x = 60 divided by 2
x = 30 yards
60 + 80 + 30 = 170 yards

The scores of the students on a standardized test are normally distributed, with a mean of 500 and a standard deviation of 110. What is the probability that a randomly selected student has a score between 350 and 550? Use the portion of the standard normal table below to help answer the question. Z Probability 0. 00 0. 5000 0. 25 0. 5987 0. 35 0. 6368 0. 45 0. 6736 1. 00 0. 8413 1. 26 0. 8961 1. 35 0. 9115 1. 36 0. 9131 9% 24% 59% 91%.
The probability of the students to be randomly selected between 350 and 550 will be 0.2395 or 24%
What will be the probability?we know that the formula for probability is given by
[tex]Z=\dfrac{X-\mu }{\sigma}[/tex]
where,
Z = Z score,
X = raw score,
μ = mean,
σ = standard deviation,
The probability of the students to be selected randomly between 350 and 550 will be given as
[tex]=P(350 < X < 550)[/tex]
[tex]=P(350-500 < X-500 < 550-500)[/tex]
[tex]=P(\dfrac{350-500}{110} < \dfrac{X-500}{110} < \dfrac{550-500}{110}[/tex]
[tex]=P(-1.36 < Z < 0.45)[/tex]
[tex]=P(Z-1.36)-P(Z-0.45)[/tex]
[tex]=(0.9131-0.6736)[/tex]
[tex]=0.2395[/tex]
Thus the probability of the students to be randomly selected between 350 and 550 will be 0.2395 or 24%

A bank offers a savings account that earns 0.5% interest each month.
Write an equation for the balance of the savings account after Y months.
Given an initial deposit of 500$ what will the account balance be after 15 months.
Answer
Step-by-step explanation:
This is exponential growth, so we would use the following equation
y=a(b)^x
500(1.005)^15
1. Initial amount is $500, since that's what we started with.
2. Add the following percentage by 100%
100%+0.5%= 1.005
3. We need to find the account balance after 15 months so raise it to the 15th power.
y= 500(1.005)^15
The balance after 15 months will be $538.84.

What is the image of (x,y) after a translation of 3 units left and 7 units down?
Answer:
[tex](x + 3, y - 7)[/tex]
Step-by-step explanation:
Given
[tex]Function = (x,y)[/tex]
Translation:
[tex]Left = 3\ units[/tex]
[tex]Down = 7\ units[/tex]
Required
Determine the image of the function
Apply the first translation
[tex]Left = 3\ units[/tex]
When function (x,y) is 3 units translated left, we add the units to the x value.
The new function becomes:
[tex](x,y) -> (x + 3, y)[/tex]
Apply the second translation
[tex]Down = 7\ units[/tex]
We subtract 7 units from the y value
[tex](x,y) -> (x + 3, y)[/tex]
becomes:
[tex](x + 3, y) ->(x + 3, y - 7)[/tex]
Hence:
The image of the function is:
[tex](x + 3, y - 7)[/tex]

what is the perimeter of rectangle JKLM
Find lengths by reasoning shortcut
JK=6-1=5unitsJM=6-3=3unitsIts a rectangle
Perimeter:-
2(JK+JM)=2(5+3)=2(8)=16units
Answer:
Perimeter = distance around a two-dimensional shape
⇒ Perimeter of a rectangle = (2 × width) + (2 × length)
From inspection of the diagram:
width = 3 unitslengths = 5 units⇒ Perimeter of the rectangle = (2 × 3) + (2 × 5)
= 6 + 10
= 16 units
The numbers 20 through 30 were written on individual cards and placed in a bag. If you take one card from the bag, what is the probability that it will not have the digit 2 on it?
Answer:
1/10
Step-by-step explanation:
20 21 22 23 24 25 26 27 28 29 30
X. X. X. X. X. X. X. X. X. X. V
1/10
20-29 all have a 2 in it meaning 30 is the only digit that doesnt have a 2 so 1/10 numbers
If one card taken from the bag then the probability that will not have the digit 2 on it is 1/11.
What is probability ?Probability shows possibility to happen an event, it defines that an event will occur or not. The probability varies from 0 to 1.
Given that,
Numbers from 20 to 30 are written on individual cards.
The total numbers of cards = 11
And numbers on cards = 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30
To find the probability of cards that have not the digit 2 on it.
Since, there is only one digit 30, which does not have digit 2,
Therefore, probability = favorable outcome / total outcome
= 1 / 11
The required probability of choosing a card that will not have the digit 2 on it is 1/11.

Ameezy has four times as many water bottles
as Beetle does. If the two of them have a
combined total of sixty bottles, how many
more bottles does Ameezy have than Beetle?
Answer:
30
Step-by-step explanation:
15 x 4 = 60, which means that Beetle has 15 bottles of water and that Ameezy has bottles. 45 - 15 = 30.
Hope this helps :)
Answer:
36 bottles.
Step-by-step explanation:
If you wrote them out, like 1 over 4, 2 over 8, and added up their totals at the bottom, you would eventually reach 60. The last column has 12 over 48, so we subtract 12 from 48, which gives us 36. So the answer is 36 bottles.
