What is the distance between two points?The distance between two points is defined as the length of the line segment between two places representing their distance.
Given AB with coordinates A(-4,5) and B(12,13).
The formula of the distance between two points is A(x₁, y₁) and B(x₂, y₂) is given by: d (A, B) = √ (x₂ – x₁)² + (y₂ – y₁) ².
x₁ = -4, y₁ = 5
x₂ = 12, y₂ = 13
distance = √ (12 – (-4))² + (13 – 5)²
distance = √ (12 + 4)² + (8)²
distance = √ (16)² + (8)²
distance = √ (256 + 64)
distance = √320
distance = 17.88 units
The horizontal distance is 16 units and the vertical distance is 8 units from A to B which are determined by the graphing method.

Time Tracking Stocks Gain/Loss -$2.25 -$1.50 $1.25 Day 1 Day 2 Day 3 Day 4 Day 5 Day 6 Day 7 Day 8 -$1.75 $3.75 -$2.50. After the first five days of tracking the stock how much in total did the stock gain or lose in value
Answers
To find how much di the stock gain or lose in value after 5 days, we just have to sum the values of the Gain/Loss column from the first row to the fifth one, like this:
Total gain or loss = -2.25 + (-1.5) + 1.25 + (-0.75) + 2.25 = -1
Then, the stock lose $1 in value ($-1)

We need to write an equation relating x (leg CD) to the given data.
The image shows the right triangle ACD, with legs, in ft, given by:
[tex]\begin{gathered} AC=1600 \\ \\ CD=x \end{gathered}[/tex]Also, angle DAC is 25.4º. Since CD is the opposite leg, and AC is the adjacent leg to this angle, we have:
[tex]\begin{gathered} \tan 25.4\degree=\frac{CD}{AC} \\ \\ \tan 25.4\degree=\frac{x}{1600} \end{gathered}[/tex]Thus, option A is correct.
Also, we can multiply both sides of the above equation by 1600, to find the equivalent equation:
[tex]\begin{gathered} 1600\cdot\tan 25.4\degree=\frac{x}{1600}\cdot1600 \\ \\ 1600\cdot\tan 25.4\degree=x \\ \\ x=1600\cdot\tan 25.4\degree \end{gathered}[/tex]Thus, option C is also correct.
Notice that:
[tex]\begin{gathered} \cos 25.4\degree=\frac{AC}{AD} \\ \\ \cos 25.4\degree=\frac{1600^2^{}+x^2}{1600} \end{gathered}[/tex]Therefore, only options A and C are correct.
A local bakery has determined the probability distribution for the number of cheesecake that they sell in a given date that X = number of cheesecake sold on organismly selected day

Having the probability distribution in the range from 0 to 20, the sum of all probabilities should give 1. This will be useful to estimate the missing value (P(x = 15)).
Let's establish the sum of probabilities:
[tex]P(x=0)+P(x=5)+P(x=10)+P(x=15)+P(x=20)=1[/tex]Now, we can replace values and solve for P(x = 15):

Now, to estimate the probability of selling at least 10 cheesecakes can be calculated by summing the probabilities of selling 10, 15, or 20. In this case, we include the 10 because it says at least. Then:
[tex]P(x\ge10)=P(x=10)+P(x=15)+P(x=20)[/tex]Replacing values:
[tex]P(x\ge10)=0.21+0.28+0.1[/tex][tex]P(x\ge10)=0.59[/tex]The probability of selling at least 10 is 0.59 (59%))

Answers
S5 = 20
A6 = 25
A1=
d=
The general formula for arithmetic sequence is:
An = A1 + (n - 1)d
25 = A1 + 6d - d (1)
And the formula for arithmetic sum:
Sn = n(A1 + An)/2
20 = 5(A1 + 25 - d)/2
8 = A1 + 25 - d (2)
We have a system of two equations with two variables.
25 = A1 + 5d
8 = A1 + 25 - d
For both equations, we can solve for d and then equal both equations as follows:
5 - A1/5 = d (1)
A1 + 17 = d (2)
A1 + 17 = 5 - A1/5
A1 = -10.
Now we just replace the value of A1 in equation 1:
d = 7
Which of the following events are NOT independent?Select one:A coin is tossed twice in a row.OA red jelly bean is taken from one jar and a yellow jelly bean istaken from another jar.OA card is drawn from a standard deck, and then another cardis drawn without the first one being replaced.A bag contains 2 red marbles, 5 blue marbles, and 3 greenmarbles. A marble is picked and then placed back in the bag.Then another marble is picked.
Answers
Solution:
We are required to determine which of the events given in the options are NOT independent?
Note: Not independent in another words means dependent.
Thus, the question is asking us to pick the option that is dependent.
Firstly, let us look at what dependent events are.
Events are dependent if the outcome of one event affects the outcome of another. For example, if you draw two colored balls from a bag and the first ball is not replaced before you draw the second ball then the outcome of the second draw will be affected by the outcome of the first draw.
Now that we understand what dependent events are, let us use that knowledge to select the correct option
(1) A coin is tossed twice in a row.
The outcome of the second throw is not affected by the first throw. Thus, these events are independent
(2) A red jelly bean is taken from one jar and a yellow jelly bean is taken from another jar:
The outcome of the yellow jelly bean taken from one jar is not affected by A red jelly bean is taken from another jar. Thus, these events are independent
(3) A card is drawn from a standard deck, and then another card is drawn without the first one being replaced.
Since the first card drawn is not replaced, the other cards drawn will be dependent on the type of card drawn in the first draw. Thus, these events are dependent
(4) A bag contains 2 red marbles, 5 blue marbles, and 3 green marbles. A marble is picked and then placed back in the bag. Then another marble is picked.
Since the first marble picked is replaced before picking the second one, the second draw will not be affected by the first draw. Hence, these events are independent
Conclusion:
The correct answer is the third option. That is "A card is drawn from a standard deck, and then another card is drawn without the first one being replaced"

Pythagoras theorem:
Pythagoras theorem states that “In a right-angled triangle, the square of the hypotenuse side is equal to the sum of squares of the other two sides“.
Given,
A triangular frame has two side lengths measuring 18 inches and 12 inches.
Here we need to find the possible length of the third sides.
WE know that, the third side of a must be greater than the sum of the other two sides.
So, we have to add the given sides then w get get the value,

The linear equation that passes through (-2, 11) and (1, -4) is:
y = -5*x + 1
How to get the linear equation?The general linear equation is:
y = a*x +b
Where a is the slope and b is the y-intercept.
If the line passes through points (x₁, y₁) and (x₂, y₂) then the slope is:
a = (y₂ - y₁)/(x₂ - x₁)
Here we know that the line passes through the points (-2, 11) and (1, -4), then the slope is:
a = (-4 - 11)/(1 + 2) = -15/3 = -5
y = -5*x + b
To find the value of b, we use one of the two given points, here i will use (1, -4), it gives:
-4 = -5*1 + b
-4 + 5 = b
1 = b

Answers
Using proportions, the number of sections that will be in the finished fence is of:
8.5 sections = 8 and 1/2 (as a mixed number).
What is a proportion?A proportion is a fraction of a total amount, and arithmetic operations such as multiplication or division are used to find the equivalent amounts.
In the context of this problem, we have that the relevant lengths are given as follows:
Each section is of 4.5 feet long.The total length of the fence is of 38.25 feet.Hence, applying a rule of three, as the total length is proportional to the length of each section, the number of sections is given by the division of the total length of the fence by the length of each section, as follows:
Number of sections = 38.25/4.5 = 8.5 sections = 8 and 1/2 (as a mixed number).
