The probability that Colleen selected a bottle of water and then a bottle of lemonade without replacement is 35/138
What is probability and multiplication rule of probability?Probability is the measure of that how likely is an event can occur.
Probability of an event = Favorable outcomes of the event / total outcomes
Multiplication rule of probability states that probability of two events happening at the same time = (probability of one event )*(probability of another event )
Given that A cooler contains 14 bottles of water and 10 bottles of lemonade. Colleen randomly selects 2 bottles from the cooler
Total bottle = 14 +10 = 24
Let E be the event that Colleen selects a bottle of water first
Probability of E = 14/24
Let F be an event that Colleen selects bottle of lemonade when at the same time a bottle of lemonade is already taken out
Probability of F = 10/23
Therefore , The probability that Colleen selected a bottle of water and then a bottle of lemonade without replacement is
= Probability of E * Probability of F = (14/24)*(10/23) =35/138.

A. -29 + 81
B. |89 - 21|
C. |81 - (-29)|
D. 36 divided 6
Option c is correct i.e., |81 - ( -29)|
On January 1, the high temperature was 81 F in Kona and the low temperature was - 29 F in Barrow.
We have to find the difference between the two temperatures.
So the difference between is
= 81 - (- 29)

The duck pond game at the capital has a pool whit 75 toy ducks twenti-five of these duck are marked undemeant
Let us organize the information first. The game consists in picking up a numbered duck. Let us denote the number of the duck as xx. The possible prizes are
1≤ x≤ 60 consolation prize
60 ≤ x ≤ 70 stuffed duck
70≤ x ≤ banana
We have 75 possible numbers equally likely to select, and 1111 outcomes where we win the stuffed duck
60, 61, 62, 63, 64, 65, 66, 67, 68, 69 and 70
Therefore, the probability of winning a stuffed duck is
p(60 ≤ x ≤ 70) = 11/75= 0.146
The event of not winning a duck or a banana is that of winning the consolation prize, that is, picking a number 1 ≤x ≤ 60.
Those are 59 equally likely to occur outcomes. Then we have
c= 59/75= 0.786
To check whether this result is right, we can use the complementary events law. That is, the probability of not winning a duck or a banana is 11 minus the sum of the probabilities of winning a duck or a banana. Mathematically this is
p (1 ≤ x ≤ 60) = 1-(p (60≤x≤70)+p(70≤x≤75)
p (1≤ x ≤ 60) = 0.786
which is a desired result.

We need to know about logarithm to solve this problem. The greatest integer that is less than the value of log 5 is 0.
Logarithm is the exponent that is raised to a base to get a certain number. There are a few rules of algorithm, log a+ log b can be written as log ab, log a -log b can be written as log a/b, when a number whose logarithm is being calculated is raised to a certain power then the power can be directly multiplied to the log itself. Logarithm when written as log has a base of 10, the logarithm of a number that is same as it's base is always 1, the log of 1 is always zero, because any nonzero number raised to 0 is 1.We will find the value of log 5 first and then choose the nearest integer that is less than log 5.

Find the length
Of the three line segments that form the triangle pictured below. The units of the grid each represent one centimeter.
4. Show your work or discribe how you found the length of the diagonal segment AB
5. Give the x-coordinate of the midpoint of AC. X=?
6.( same thing as 5 just with BC)
7.(same thing as 6,and 5 just with AB)
Step-by-step explanation:
for the lengths of BC and AC we can count the squares, because the lengths of these lines are the sum of the side lengths of each inducing square.
1.
BC = 7 - -2 = 7 + 2 = 9 cm
2.
AC = 13 - 1 = 12 cm
3.
but for AB we cannot do that, because AB consists of the lengths of all the diagonals of the squares. and a diagonal must always be longer than any side.
just look at the triangle : it is clear that AB must be longer than AC.
no, for a line that goes across the grid squares we need other methods.
in our case, we have a right-angled triangle and can use Pythagoras
c² = a² + b²
c being the Hypotenuse (the side opposite of the 90° angle), a and b being the legs of the triangle (enclosing the 90° angle).
AB is in our case the Hypotenuse, and we get
AB² = 12² + 9² = 144 + 81 = 225
AB = sqrt(225) = 15 cm
4.
as explained, we used Pythagoras.
5.
the coordinates for a midpoint between 2 points (x1, y1) and (x2, y2) are simply
((x1+x2)/2, (y1+y2)/2)
A = (13, -2)
B = (1, 7)
C = (1, -2)
midpoint AC = ((13+1)/2, (-2 + -2)/2) = (14/2, -4/2) =
= (7, -2)
the x coordinate is 7.
6.
midpoint BC = ((1+1)/2, (7+ -2)/2) = (2/2, 5/2) = (1, 2.5)
the y coordinate is 2.5
7.
midpoint AB = ((13+1)/2, (-2+7)/2) = (14/2, 5/2) =
= (7, 2.5)

How long would it take to double your principal in an account that pavs 6.5 % annual interest compounded continuously?
It will take 4.63 years to double the principal.
The formula for calculating the amount (A) on a principal (P) invested at the rate of r%, compounded continuously after t years is-
A = P[tex]e^{rt}[/tex]
Here r = 6.5%
= 0.065
Let the principal amount be P,
then the amount after t years = 2P
A = P[tex]e^{rt}[/tex]
2P = P[tex]e^{rt}[/tex]
2P/P = [tex]e^{rt}[/tex]
2 = [tex]e^{0.065t}[/tex]
Taking log on both sides-
Log 2 = log [tex]e^{0.065t}[/tex]
Log 2 = 0.065t log e
Log 2 = 0.065t
0.65t = Log 2t
= log 2/ 0.065t
= 0.301/ 0.065 t
= 4.63

Definition:-In mathematics, the additive inverse of a number a is the number that, when added to a, yields zero. This number is also known as the opposite, sign change, and negation.
For example, the additive inverse of 7 is −7, because 7 + (−7) = 0, and the additive inverse of −0.3 is 0.3, because −0.3 + 0.3 = 0. Similarly, the additive inverse of a − b is −(a − b) which can be simplified to b − a. The additive inverse of 2x − 3 is 3 − 2x, because 2x − 3 + 3 − 2x = 0.
