Answer:
60.5%
Step-by-step explanation:
60% white, 40% black
The first draw you have a 60% chance drawing a white marble, the second time you have a 55% chance since you already drew one in the first round. so i think it is 60.5%% chance drawing white on both rounds since I add 60+55=121. 121/200=60.5%

42 inches
O 74 inches
58 inches
48 inches
O
Answer:
58 inches
Step-by-step explanation:
Perimeter means the sum of length of all sides of a figure.
So, the perimeter of this triangle would also be the sum of the length of its sides.
It has 3 sides.
19 in, 16 in and 23 in.
So, its perimeter equals 19 + 16+ 23
which equals 58 inches!
So, the perimeter would be 58 inches.!

B and F are non-statistical questions
Step-by-step explanation:
B is asking how many years until you are 16; this is not statistical because it just a fact. F is pretty much the same because it's just asking a subjective fact-like question.
Statistical questions ask for a collection of varying data. If there is only one data point, it is non-statistical.

A triangle has three angles of 36°, 34°, and 110°.
A. equilateral B. obtuse C. acute D. right
Answer:
Obtuse Triangle.
Step-by-step explanation:
An obtuse-angled triangle is a triangle in which one of the interior angles measures more than 90° degrees. In this case, 110° is more than 90°. So, its an obtuse angle. If one angle of the triangle is obtuse, then the other two angles with always be acute.
Hence, this is an obtuse triangle
The triangle with the given measures is obtuse angle triangle. Therefore, option B is the correct answer.
What is an obtuse angle triangle?An obtuse-angled triangle is a triangle in which one of the interior angles measures more than 90° degrees. In an obtuse triangle, if one angle measures more than 90°, then the sum of the remaining two angles is less than 90°.
Given that, a triangle has three angles of 36°, 34°, and 110°.
Here, one of the angle measure more than 90°, that is 110°.
Sum of remaining two angles is 36°+34°
= 70°
Therefore, option B is the correct answer.

how do i find this out?
Answer:
8
Explanation:
A good way to find the area of a figure with diagonal lines is to find the area of the section that has full squares and then add the other parts together and find the area of that. As you can see in the polygon, there are four units in the middle that don't get cut off by the diagonal line. The area of that part of the figure is 1*4 = 4. Now, if you take out that section, and move the other parts together, you can find their area and then add it to 4. The other parts of the polygons are triangles, and when you move them together, they form the same shape as the middle section did, and have an area of 4. The area of the entire figure is the area of one section plus the area of the other. 4 + 4 = 8

30 pts ! The height of the Ferris wheel in feet can be represented by the function 50 cos (π/15(x-10))+52 with time in x seconds. When does the height of 80 feet occur on the interval 0
The time that the height of 80 feet occur on the interval 0 is 4.662 seconds.
Given:
50 cos (π/15(x-10))+52
Height=80 feet
Time= x second
Hence:
height (h)= 50 cos [pie(x - 10 )/15 ] + 52
80 = 50 cos [pie( x - 10 )/15 ]+ 52
Collect like terms
80 - 52 = 50 cos [ pie( x - 10 )/15 ]
28 = 50 cos [ pie( x - 10 )/15 ]
cos [pie( x - 10 )/15 ] = 28/50
cos [ pie( x - 10 )/15 ] =56
cos [pie( x - 10 )/15 ]= cos ( 56 )
cos [ pie( x - 10 )/15 )]= cos ( 0.3111 pie )
Hence:
pie( x - 10 )/15 = 0.3111
( x - 10 )/15 = 0.3111
x - 10 = 15 × 0.3111
x - 10 = 4.662
x = 10 + 4.662
x = 14.662 seconds

A grocery chain runs a prize game by giving each customer a ticket that may win a prize when the box is scratched off. Printed on the ticket is a dollar value ($500, $100, $25) or the statement "This ticket is not a winner." Monetary prizes can be redeemed for groceries at the store. Below is the probability distribution of the amount won on a randomly selected ticket. Which of the following are the mean and standard deviation, respectively, of the winnings? * 2 points Captionless Image $156.25 $53.85 $15.00, $2900.00 $15.00, $26.93 $15.00, $53.85 $156.25, $26.93
Answer:
[tex]Mean = \$15[/tex]
[tex]Standard\ Deviation = \$53.85[/tex]
Step-by-step explanation:
Given
See attachment for probability distribution
Required
Determine the mean and the standard deviation
The mean of the distribution is:
[tex]Mean = E(x)[/tex]
and
[tex]E(x) = \sum x * P(x)[/tex]
So, we have:
[tex]Mean = \$500 * 0.01 + \$100 * 0.05 + \$25 * 0.20 + \$0 * 0.74[/tex]
[tex]Mean = \$5 + \$5 + \$5 + \$0[/tex]
[tex]Mean = \$15[/tex]
So:
[tex]E(x) = 15.00[/tex]
The standard deviation of the distribution is:
[tex]S = \sqrt{Var(x)}[/tex]
Where:
[tex]Var(x) = E(x^2) - (E(x))^2[/tex]
[tex]E(x^2) = \sum x^2 * P(x)[/tex]
So, we have:
[tex]E(x^2) = 500^2 * 0.01 + 100^2 * 0.05 + 25^2 * 0.20 +0^2 * 0.74[/tex]
[tex]E(x^2) = 2500 + 500 + 125 +0[/tex]
[tex]E(x^2) = 3125[/tex]
So:
[tex]Var(x) = E(x^2) - (E(x))^2[/tex]
Where
[tex]E(x^2) = 3125[/tex]
[tex]E(x) = 15.00[/tex]
[tex]Var(x) = 3125 - 15^2[/tex]
[tex]Var(x) = 3125 - 225[/tex]
[tex]Var(x) = 2900[/tex]
Recall that:
[tex]S =\sqrt{Var(x)[/tex]
[tex]S =\sqrt{2900[/tex]
[tex]S =53.85[/tex]
Your business has two branch stores. The recent physical inventory reports that the merchandise value for each store is: Store A $750,000, and Store B $580,000. The merchandise book value for each store is: Store A $757,000, and Store B $600,000. What is the dollar amount of shrinkage for each store?
Answer: Store A: 7,000 Store B: 20,000
Step-by-step explanation:
The amount of shrinkage for store A is $7000 and for store B is $20000.
What is loss?"If the selling price of an item is less than the cost price, then the difference between the cost price and the selling price of an item is called the loss".
For the given situation,
The merchandise book value for store A = $757,000
The merchandise book value for store B = $600,000
Based on physical inventory reports,
The merchandise value for store A = $750,000
The merchandise value for store B = $580,000.
The amount of shrinkage determines the loss and it is calculated by taking the difference between the values.
Store A = [tex]757000-750000[/tex]
⇒ [tex]7000[/tex]
Sore B = [tex]600,000-580000[/tex]
⇒ [tex]20000[/tex]
Hence we can conclude that the amount of shrinkage for store A is $7000 and for store B is $20000.

Need some assistance yall look at picture :) Algebra 2 type vibe
Answer:
It is C.
III is saying that the two functions are inverse functions. If two functions, f(x) and g(x) are inverse, then f(g(x)) = x and g(f(x)) = x. Therefore, we see that if III is true, then I and II should also be true. Now, all we have to prove is that f(x) and g(x) are inverse functions. As we said before, if two functions are inverse, then f(g(x)) = x and g(f(x)) = x.
f(g(x)) = 3([tex]\sqrt[3]{\frac{x-2}{3} }[/tex])^3 + 2
f(g(x)) = 3[(x-2)/3]+2
f(g(x)) = x-2 + 2
f(g(x)) = x
Therefore, we have proved that f(g(x)) = x, and so f(x) and g(x) are inverse functions, and so all of I, II, and III are true. Thus, the answer is C.
fyi, we didn't have to do g(f(x)) because if f(g(x)) = x, then so will g(f(x)).
Alonzo worked for 13 hours each day for 6 days then he worked 7 hours how many hours it Alonzo work in all?
Answer:
85 hours
Step-by-step explanation:
Number of hours per day = 13 hours
Number of days = 6
Number of hours worked for 6 days = 6 days × 13 hours
= 78 hours
then he worked 7 hours
Total Number of hours worked = Number of hours worked for 6 days + 7 hours
= 78 hours + 7 hours
= 85 hours
Total Number of hours worked = 85 hours

K=1/2mv square root of 2
rearrange for m:
Answer: V = The square root of (2K/M)
We are starting with the formula: K = 0.5MV^2
Our first steps to isolate V would be to multiply by 2 and divide by M on both sides of the equation.
2K/M = V^2
Now, we just have to take the square root of both sides of the equation
The equation rearranged for m is [tex]m = (2K) / v^2[/tex].
This equation allows us to calculate the mass (m) when the kinetic energy (K) and the velocity (v) are known.
To rearrange the equation [tex]K = (1/2)mv^2[/tex] for m, we can follow these steps:
Step 1: Multiply both sides of the equation by 2 to remove the fraction:
[tex]2K = mv^2[/tex]
Step 2: Divide both sides of the equation by[tex]v^2[/tex] to isolate m:
[tex](2K) / v^2 = m[/tex]
Therefore, the equation rearranged for m is [tex]m = (2K) / v^2[/tex].
This equation allows us to calculate the mass (m) when the kinetic energy (K) and the velocity (v) are known.
