A bag has 5 yellow marbles, 3 red marbles and 2 blue marbles. Quinn randomly picks a marble from the bag and returns it before another is picked. How many times would Quinn expect to pick a blue marble if he picks a marble 200 times?
Answer:
20%
Step-by-step explanation:
or 20 because since there is 5 and 3 you ad them and you get 5, 5+5 =10 and its like 100 but its not so, 2 of 10 is like saying 20% of 100
Answer:
40
Step-by-step explanation:
200/10=20
There are 2 blue marbels so 20x2=40
Suppose a city with population 300,000 has been growing at a rate of 2% per year. If this rate continues, find the population of this city in 20 years
I need help solving this
Answer:
the answer is 445,784
Step-by-step explanation:
The population y after x years of growth with the growth rate r and the original population C can be found using the exponential growth formula, . Substitute the decimal equivalent for the percent growth rate per year for r.
Find the equation of a line that contains the points (4,−1) and (−1,−4). Write the equation in slope-intercept form, using fractions when required.
Answer:
y = 3/5x - 17/5
Step-by-step explanation:
slope formula: (y₂ - y₁) / (x₂ - x₁)
First, plug in these values of the two given points.
(-4 - (-1)) / (-1 - 4)
Simplify within the parentheses.
(-4 + 1) / (-1 - 4)
(-3) / (-5)
3/5
This is your slope. Plug this into a standard slope-intercept equation: y = mx + b
To find b, we want to plug in a value that we know is on this line: in this case, I will use the second point (-1, -4). Plug in the x and y values into the x and y of the standard equation.
-4 = 3/5(-1) + b
Multiply.
-4 = -3/5 + b
Add 3/5 to both sides. -- To add it easier, convert 4 to a have a denominator of 5.
-20/5 = -3/5 + b
-20/5 + 3/5 = b
-17/5 = b
Now, plug this into your standard equation.
y = 3/5x - 17/5
Check this equation by plugging in the other point you did not use (4, -1)
-1 = 3/5(4) - 17/5
-1 = 12/5 - 17/5
-1 = -5/5
-1 = -1
Your answer is correct!
Hope this helps!

-4) and C (5,8). What
Is the length, in units,
of AC.
9514 1404 393
Answer:
13 units
Step-by-step explanation:
The distance formula is useful for this.
d = √((x2 -x1)² +(y2 -y1)²)
d = √((5 -0)² +(8 -(-4))²) = √(25 +144) = √169
d = 13
The length of AC is 13 units.

Convert the equation `5x+2y=-8`into slope-intercept form.
Answer:
y= -2.5x-4
Step-by-step explanation:
we have to isolate our y
subtract 5x from 5x+2y=-8 and move it to the right side
2y= -5x-8
divide everything by 2
y=-2.5x-4

Dan buys a car for £2200.
It depreciates at a rate of 0.5% per year.
How much will it be worth in 6 years?
Give your answer to the nearest penny
Answer:
The worth of the car after 6 years is £2,134.82
Step-by-step explanation:
The amount at which Dan buys the car, PV = £2200
The rate at which the car depreciates, r = -0.5%
The car's worth, 'FV', in 6 years is given as follows;
[tex]FV = PV \cdot \left ( 1 + \dfrac{r}{100} \right )^n[/tex]
Where;
r = The depreciation rate (negative) = -0.5%
FV = The future value of the asset
PV = The present value pf the asset = £2200
n = The number of years (depreciating) = 6
By plugging in the values, we get;
[tex]FV = 2200 \times \left ( 1 + \dfrac{-0.5}{100} \right )^6 \approx 2,134.82[/tex]
The amount the car will be worth which is its future value, FV after 6 years is FV ≈ £2,134.82 (after rounding to the nearest penny (hundredth))
The volume of a sphere is two-thirds of a cylinder. What is the volume of a cylinder that has the same diameter as a sphere with a volume of 14 u^3, in u^3
Answer:
[tex]V_2= \frac{28}{3} u^3[/tex]
Step-by-step explanation:
Given
Represent the volume of the cylinder with V1 and the volume of the sphere with V2
So, from the first statement: we have:
[tex]V_2 =\frac{2}{3}V_1[/tex]
and
[tex]V_1 = 14u^3[/tex]
To solve for [tex]V_2[/tex], we simply substitute [tex]14u^3[/tex] for [tex]V_1[/tex] in [tex]V_2 =\frac{2}{3}V_1[/tex]
[tex]V_2 =\frac{2}{3}V_1[/tex]
[tex]V_2= \frac{2}{3} * 14u^3[/tex]
[tex]V_2= \frac{2* 14}{3} u^3[/tex]
[tex]V_2= \frac{28}{3} u^3[/tex]
Hence, the volume of the sphere is [tex]\frac{28}{3} u^3[/tex]

Answer:
x,y =3,-4
Step-by-step explanation:
// Solve equation [1] for the variable y
[1] y = 2x - 10
// Plug this in for variable y in equation [2]
[2] 3x - 2•(2x-10) = 17
[2] -x = -3
// Solve equation [2] for the variable x
[2] x = 3
// By now we know this much :
x = 3
y = 2x-10
// Use the x value to solve for y
y = 2(3)-10 = -4

If a point, ray, line, line segment, or plane intersects a segment at its midpoint, then it is?
Answer:
If A Point, Ray, Line Segment, or Plane intersects a segment at its midpoint, then it Bisects the segment.
Step-by-step explanation:A segment, ray, line, or plane that is perpendicular to a segment at its midpoint is called a perpendicular bisector. If a point is on the perpendicular bisector of a segment, then it is equidistant from the endpoints of the segment. Point is equidistant from two points if its distance from each point is the same.

What type of quadrilateral is ABCD? Move segments and words to blanks to classify quadrilateral ABCD
The quadrilateral that is illustrated based on the information and diagram is a square.
What is a quadrilateral?A quadrilateral is a plane figure with four edges and four corners, also known as vertices. The quadrilateral's four vertices or corners all have angles. A quadrilateral has four straight sides and is a two-dimensional shape. Parallelograms, trapezoids, rectangles, kites, squares, and rhombuses are a few examples of quadrilaterals.
A quadrilateral with four equal sides and angles is called a square. Due to its equal sides and angles, it is also a regular quadrilateral. A square has four 90° angles, just like a rectangle does. It can also be thought of as a rectangle with equal lengths on its two adjacent sides. A square is a quadrilateral with four equal sides and four equal angles that is a regular quadrilateral. The square's angles are at a right angle or 90 degrees.
