There are 20 black, 15 white, 12 green, 12 red, 9 blue, and 2 yellow candies in a box. How many candies should you take (without looking at them) to be sure that you have at least 3 candies the same color
Answer:
13
Step-by-step explanation:
Because the problem says to make sure we have at least 3 candies of the same color, we have to think about the worst-case scenario. To get the worst-case scenario, we need to have the largest amount of candies taken before fulfilling the statement that 3 candies have the same color, so we take 2 black, 2 white, 2 green, 2 red, 2 blue, and 2 yellow candies. This sums to 12, and you have the worst case scenario here. But wait, you've picked only 2 of each candy. You have to pick one more candy to make sure you have 3 candies of the same color, so the answer is 12 + 1 = 13 candies.
Plot the point (11, 7) on the coordinate plane.
Answer:
Step-by-step explanation:
When you're asked to plot a point on a coordinate plane just remember that the coordinate given is of the form [tex](x,y)[/tex].
So, first, we need to plot 11 on the [tex]x[/tex]-axis (the line going left to right, horizontal) then plot 7 on the [tex]y[/tex]-axis (the vertical line)
So we first go 11 units to the right along the [tex]x[/tex]-axis then go up 7 units along the [tex]y[/tex]-axis.
Hope this helped.

if a hot air balloon owner charges $150 for one hour ride if he gives 6 rides on Saturday and 5 rides on Sunday write and evaluate an expression to describe his total income for the weekend
Answer:
Your expression would be 150(11)=x
The answer to this expression would be 1,650. Producing the equation 150(11)= 1,650
Step-by-step explanation:
Your equation is 150(11)=x because; the hot air balloon owner charges $150 per ride. And there are 11 rides. So our equation is solely saying $150 charged per ride for 11 rides.
Let's solve this equation
150(11)= 1,650
So, we would multiply 150 by 11 to get 1,650.
And if your professor asks a statement for your equation you would say; The total income for the balloon owner that weekend is $1,650. $900 made on Saturday plus $750 made on Sunday.

(x − 5)^2 = x^2 − 25
Answer:
x=5
Step-by-step explanation:
x^2+25-10x = x^2-25
-x^2 -x^2
25-10x = -25
-25 -25
-10x = -50
x=5
lets check
(5-5)^2 = 5^2-25
0^2 = 25-25
0 = 0
Answer:
x = 5
Step-by-step explanation:
(x - 5)^2 = (x - 5) (x - 5) =
x^2 -10x + 25 = x^2 - 25
x^2 - x^2 - 10x + 25 = - 25 (x^2 - x^2 = 0)
- 10x + 25 = - 25
- 10x = - 25 - 25
x = - 50/- 10
x = 5
find f(x)=x^2-x^3,find f(-10)
Answer:
Value of f(-10) is 1100
Step-by-step explanation:
Given that f(x) = x² - x³
Here we need to find f(-10).
f(-10) = (-10)² - (-10)³
f(-10) = 100 - (-1000)
f(-10) = 100 + 1000
f(-10) = 1100
Value of f(-10) is 1100

Answer:
YesStep-by-step explanation:
Given:
f(x) = 4xg(x) = x/4Find the following:
f(g(x)) = 4*g(x) = 4*x/4 = xg(f(x)) = f(x)/4 = 4x/4 = xSince f(g(x)) = g(f(x)) = x, the functions are inverses of each other.

supose that the half-life of a cesium is 30 years. If there were initially 1000g of the substance,
a) give an exponential model for the situation
b) how much will remain after 200 years
After 200 years, 9.84 grams of Cesium would remain.
Let N represent the amount of substance after t years
The half-life of a cesium is 30 years., hence, this can be represented by exponential function:
[tex]N(t)=ab^t[/tex]
where a is the initial value and b is the multiplier.
There were initially 1000g of the substance
a) The exponential model for this situation is:
[tex]N(t) =1000(\frac{1}{2} )^{\frac{1}{30} t}\\\\N(t) =1000(\frac{1}{2} )^{\frac{t}{30}[/tex]
b) After 200 years (t = 200), the amount of Cesium remaining is:
[tex]N(200)=1000(\frac{1}{2} )^\frac{200}{30} \\\\N(200) = 9.84g[/tex]
Hence after 200 years, 9.84 grams of Cesium would remain

Find the Distance rounded to a whole number.
Give the distance between (2,1) and (5,2)
Answer:
[tex]\sqrt{10}[/tex]
Step-by-step explanation:
The distance between two points can be found using the Pythagorean Theorem [tex]a^{2} + b^{2} = c^{2}[/tex].
This is because, if you connected your two points with a line, that line could be defined as the hypotenuse of a right triangle. the base of that triange is the distance between the x coordinates ([tex]x_{2} -x_{1}[/tex]) and the height by the distance between the y coordinates ([tex]y_{2} - y_{1}[/tex]). Sine these are the sides of the right triangle, they are equal to a and b above (c is the hypotenuse that we are trying to find). So, we calculate the two distances above and get 3 and 1 (for x and y respectively). 3^2 + 1^ 2 =10. So the answer is square root 10.

If point P is between A and M, which of these is true?
A. AM + AP = PA
B. AP + PM = AM
C. PA + AM = PM
D. AM + PM = AP
Answer:
I believe it's B
Step-by-step explanation:
True option is, B. AP+PM=AM.
What is a straight line?A straight line is an endless one-dimensional figure that has no width. It is a combination of endless points joined both sides of a point and has no curve.
Here, given that, point P is between A and M,
Then, A & M are the endpoints & P is on the line.
A---------------------P--------------------M
So, we get, AP+PM= AM
Hence, True option is, B. AP+PM=AM.

Use the probability distribution to complete parts (a) and (b) below.
The number of school-related extracurricular activities per student
Activities 0 1 2 3 4 5 6 7
Probability 0.059 0.121 0.164 0.179 0.212 0.127 0.086 0.052
(a) Find the mean, variance, and standard deviation of the probability distribution.
The mean is 3.3
(Round to one decimal place as needed.)
The variance is
(Round to one decimal place as needed.)
this could take a while to think about but uhh i dont know,
The variance of the probability distribution is 3.4.
To find the variance of the probability distribution, calculate the following:
1. The squared deviation of each activity value from the mean.
2. The product of each squared deviation and its corresponding probability.
3. The sum of these products.
1. Calculate the squared deviation of each activity value from the mean (3.3):
[tex]\[ (0 - 3.3)^2 = 3.3^2 = 10.89 \]\\[/tex]
[tex]\[ (1 - 3.3)^2 = (-2.3)^2 = 5.29 \][/tex]
[tex]\[ (2 - 3.3)^2 = (-1.3)^2 = 1.69 \][/tex]
[tex]\[ (3 - 3.3)^2 = (-0.3)^2 = 0.09 \][/tex]
[tex]\[ (4 - 3.3)^2 = (0.7)^2 = 0.49 \][/tex]
[tex]\[ (5 - 3.3)^2 = (1.7)^2 = 2.89 \][/tex]
[tex]\[ (6 - 3.3)^2 = (2.7)^2 = 7.29 \][/tex]
[tex]\[ (7 - 3.3)^2 = (3.7)^2 = 13.69 \][/tex]
2. the product of each squared deviation and its corresponding probability:
[tex]\[ 0.059 \times 10.89 = 0.64351 \][/tex]
[tex]\[ 0.121 \times 5.29 = 0.63909 \][/tex]
[tex]\[ 0.164 \times 1.69 = 0.27716 \][/tex]
[tex]\[ 0.179 \times 0.09 = 0.01611 \][/tex]
[tex]\[ 0.212 \times 0.49 = 0.10388 \][/tex]
[tex]\[ 0.127 \times 2.89 = 0.36703 \][/tex]
[tex]\[ 0.086 \times 7.29 = 0.62814 \][/tex]
[tex]\[ 0.052 \times 13.69 = 0.71188 \][/tex]
3. Sum up these products to get the variance:
[tex]\[ \text{Variance} = 0.64351 + 0.63909 + 0.27716 + 0.01611 + 0.10388 + 0.36703 + 0.62814 + 0.71188[/tex]
= [tex]3.38680 \][/tex]
=3.4
So, the variance is 3.4.

The speed of light is 299 792 458 m / s
Which decadic units can you round to so that only one non-zero digit is produced?
Answer:

Step-by-step explanation:
just round to the nearest 10th
Answer:
The speed of light is exactly 299,792,458 m/s because that is how a meter is defined. A meter is defined as the distance light travels in 1/299792458 seconds in vacuum. Why was this particular number chosen? To keep the definition of meter consistent with the old standard which was an actual physical bar. The length of this bar was arbitrary though.
