Answers
Answer:
Let's denote students in D = in the drama club , S = in a sports team
P(D) = 85/330
P(S) = 200/330
P(D and S) = 60/300
P(D or S) = P(D) + P(S) - P(D and S) = 85/330 + 200/330 - 60/330 = 15/22
P(neither D nor S) = 1- 15/22 = 7/22

if an ordered pair was added to the table, which of the following pairs would result in the table becoming not a function.
Please help
Answers
Answer:
C or D
Step-by-step explanation:
✔️If the ordered pair (8, 3) was added to the table, we would have two one input value, 8, having two different outputs, 4 and 3 respectively. The table therefore ceases to be a function. Each input value in a function must have only one output value. Otherwise, it ceases to be a function.
✔️Also, if we look at other options, we would see that we also have another orders pair that can make the table not to be function anymore once it's added to the table.
The ordered pair (-3, 4), when added, will make us have one input value, -3, having two output values, 4 and 6 respectively. This will make the table not to become a function.
✔️Therefore, there are two correct options, they are C or D.

$126,591
$77,184
$173,175
Calculate your annual retirement salary.
Answers
Answer:
9,149.10
Step-by-step explanation:
To get the average you take all the values and add them up then divide by 5.
767,542 divided by 5 = 153,508.40
Now to get the percentage take 5.96 and divide by 100 = 0.0596
With this you can multiple the average by the percent in decimal form.
153,508.40 * 0.0596 = 9,149.10

C. 15.7 cm
D. 31.4 cm
Answers
Answer:
31.4 cm , just did the quiz
Step-by-step explanation:
The length of the minor arc is 31.4 cm of the given circle.
What is Circle?A circle is a shape consisting of all points in a plane that are at a given distance from a given point, the centre.
Arc length is the distance between two points along a section of a curve.
The formula for arc length is θ/360×2πr
Arc length = θ/360×2πr
Where θ is the central angle and r is the radius of the circle.
θ = 60 degrees and r is 30 cm
Plug in the value of θ and r
Arc length = 60/360 × 2×3.14×30
=1/6×60×3.14
=188.4/6
=31.4
Hence, the length of the minor arc is 31.4 cm of the given circle.

Adan and Darlene have entered the Pythagorean Lake Endurance Trial. Part of the competition requires them to travel from Geoville, which is on the south side of the lake, to Triple City, which is across the lake and due north of Geoville. Adan decides to ride his scooter from Geoville to Angle Point, which is 20 miles due east of Geoville, and then continue on to Triple City. There is a direct route that runs in a straight line for 25 miles from Angle Point to Triple City. Adan's scooter can go no faster than 35 mph. Darlene thinks she can beat Adan to Triple City by taking a fishing boat (average speed 12 mph) directly from Geoville to Triple City. Who will get to Triple City first? Explain your solution.

Two angles of a triangle measure 55 and 20 what is the measure of the third angle of the triangle
Answers
Answer:
105 degrees
Step-by-step explanation:
well if we take a look at this
we know for sure that every triangle must have a total angle measurement of 180 degrees
so if we take the information we have and we add those together
55 + 20
that will give us
75
then in order to find the missing angle measurement we take the total number of degrees in a triangle and subtract the two angles together from it
180-75
giving us 105 degrees as the third measurement of the angle in the triangle
Answer:
the third measure is [tex]105[/tex]°
Step-by-step explanation:
All measures of a triangle add up to 180°
[tex]A+ B + C = 180[/tex]
[tex]20 + 55 + C = 180[/tex]
[tex]75 + C = 180[/tex]
[tex]C = 105[/tex]°

when doing proportions you have to align your fractions accordingly.
we are putting x over 64 which means that small triangle in the top and big triangle in the bottom. On the other side its going to be 36 because of the small triangle's side and in the bottom we put the big triangle's side which will be 72 because 36+36=72
You started the trail with 1400lbs. of food. You now have 1182lbs. of food. What percentage of your starting amount do you have left?
Answers
Answer:
84.5%
Step-by-step explanation:
1400 - 1182 = 218 You are less 218 lbs. of food.
218 ÷ 1400 = 15.5% You are less 15.5% lbs. of food.
100% - 15.5% = 84.5% You have 84.5% lbs if food left.

Graph the quadratic functions y =-2x^2 + 4 on a separate piece of paper. Using those graph, compare and contrast the shape and position of the graphs.
Answers
Answer:
y = 2x^2 is a parabola opening up with it's vertex at (0,0)... y=3x^2 -4 is also a parabola opening up, but it is 'thinner' in that it rises in y faster and it's vertex is at (0,-4)
Step-by-step explanation:
all equations of the type y = ax^2 + b are parabolas centered on the y-axis, soo the vertex is always on (0,b)
If a is positive then the parabola opens up,
the bigger a is, the 'thinner' the graph is, i.e. the faster the graph rises
the value of b determines the location of the vertex, if b is added, then the vertex rises over the x-axis, if b is subtracted then the vertex is below the x-axis
