Step-by-step explanation:

To find the equation of a line that is perpendicular to a given line and passes through a specific point, we need to follow a few steps:

Find the slope of the provided line.

The point-slope form of a line is given by: y - y1 = m(x - x1), where (x1, y1) represents the given point.

Substituting the values, the equation of the perpendicular line becomes:

y - 5 = (-1/m)(x - 2)

Simplifying the equation further, we can rewrite it in point-slope form:

y - 5 = (-1/m)x + (2/m)

The solution of the system of equations is , x= -16 - 10/2 = 13

According  to our question-

-2x + 5y = -16  (3) =       -6x + 15y = -48

 3x -  4y  = 17  (2) =         6x -   8y  =   34

7y =     -14

y= -14/7 = 2

-2x + 5(2) = -16

-2x + 10 = -16

x= -16 - 10/2 = 13

hence,The solution of the system of equations is , x= -16 - 10/2 = 13

Step-by-step explanation: The more pieces are cut, the smaller they get so the bigger the denominator, the bigger the piece

b) P(S) = 0.356  , c) P(S') = 0.644  ,d) P(S | R)= 0.078 e) P(R' | S')  = 0.965

is the probability of all cases according to question conditions

what is probability ?

Probability is a measures the likelihood of event occurring. It is expressed as a number between 0 and 1, with 0 indicating that the event is impossible and 1 indicating that the event is certain.

what is event occurring ?

An event is any outcome or result that can occur in a given situation. It can be a simple outcome, such as flipping a coin and getting heads, or a more complex outcome

In the given question,

a. Here is the tree diagram for the scenario:

        Rain (0.3)

        /      \

    S (0.12)   S' (0.88)

   /     \

No Rain (0.7)  S (0.53)

         \

          S' (0.47)

b. We can use the Law of Total Probability to calculate P(S):

P(S) = P(R) * P(S | R) + P(R') * P(S | R')

    = 0.3 * 0.12 + 0.7 * 0.53

    = 0.356

Therefore, there is a 35.6% chance that Sarina will go to the store on Saturday.

c. P(S') represents the probability that Sarina will not go to the store on Saturday. We can use the complement rule to calculate it:

P(S') = 1 - P(S)

    = 1 - 0.356

    = 0.644

Therefore, there is a 64.4% chance that Sarina will not go to the store on Saturday.

d. P(S | R) represents the probability that Sarina will go to the store on Saturday given that it rains. We can use Bayes' Theorem to calculate it:

P(S | R) = P(R | S) * P(S) / P(R)

        = P(S | R) * P(R) / (P(R | S) * P(S) + P(R | S') * P(S'))

        = 0.12 * 0.3 / (0.12 * 0.3 + 0.53 * 0.7)

        = 0.078

Therefore, there is a 7.8% chance that Sarina will go to the store on Saturday given that it rains.

e. P(R' | S') represents the probability that it doesn't rain given that Sarina doesn't go to the store on Saturday. We can use Bayes' Theorem to calculate it:

P(R' | S') = P(S' | R') * P(R') / P(S')

          = P(S' | R') * P(R') / (P(S | R) * P(R) + P(S' | R') * P(R'))

          = 0.47 * 0.7 / (0.078 * 0.3 + 0.47 * 0.7)

          = 0.965

Therefore, there is a 96.5% chance that it doesn't rain given that Sarina doesn't go to the store on Saturday.

The liters of 80% material is 2/3 liters.

The liters of the 50% solution is 1/3 liters.

Based on the information, the scientist is working with two different concentrations of hydrochloric acid (HCI).

Let x = volume of 80%

Let 1 -x =volume of 50%

Therefore, the expression to illustrate the information will be:

80x + 50 × (1 - x) = 70

80x + 50 - 50x = 70

30x = 70 - 50

30x = 20

Divide

x = 20/30

x = 2/3

Therefore there are 2/3 liters of 80% material

The liters for the 50% solution will be 2/3 subtracted from 1. The 2/3 implies that for the 80% material. This will be:

= 1 - 2/3

= 1/3

There are also 1/3 liters of 50% material.

144 = a^2 + 64                      Subtract 64 from both sides

80 = a^2                              Take the square root of both sides.

Question One:A positive z-score indicates that the raw score is above the mean, while a negative z-score indicates that the raw score is below the mean.

Question Two: , the raw score is relatively lower than the mean.

If a raw score corresponds to a z-score of 1.75, it tells us that the raw score is 1.75 standard deviations above the mean of the distribution. In other words, the raw score is relatively higher than the mean. The z-score provides a standardized measure of how many standard deviations a particular value is from the mean.

A positive z-score indicates that the raw score is above the mean, while a negative z-score indicates that the raw score is below the mean.

Question Two:

If a raw score corresponds to a z-score of -0.85, it tells us that the raw score is 0.85 standard deviations below the mean of the distribution. In other words, the raw score is relatively lower than the mean. The negative sign indicates that the raw score is below the mean.

To understand the meaning of a z-score, it is helpful to consider the concept of standard deviation. The standard deviation measures the average amount of variability or spread in a distribution. A z-score allows us to compare individual data points to the mean in terms of standard deviations.

In the case of a z-score of -0.85, we can conclude that the raw score is located below the mean and is relatively lower compared to the rest of the distribution. The negative z-score indicates that the raw score is below the mean and is within the lower portion of the distribution. This suggests that the raw score is relatively smaller or less than the average value in the distribution.

By using z-scores, we can standardize and compare values across different distributions, allowing us to understand the position of a raw score relative to the mean and the overall distribution.

The operation that has been performed on v to result in the vector that is shown is multiplication by -1.

The vector that is shown is (-2, -1). This can be obtained from vector v = (2, 1) by multiplying it by -1. Multiplying a vector by a negative number reverses its direction.

Multiplication of a vector by a number is performed component-wise. This means that each component of the vector is multiplied by the number. In the case of (-1) * (2, 1), each component is multiplied by -1. This results in the vector (-2, -1).

The statement " when adding an entry to a binary search tree, the search ends at a leaf if the entry is not already in the tree" is true.

A tree is a type of data structure made up of nodes and contains the following features:

1- Every tree has a root node (also known as a parent node) at the top that contains some value (can be any datatype).

2- There are 0 or more child nodes of the root node.

3- There are zero or more child nodes for each child node, and so forth. As a result, the tree gains a subtree. Each node has a separate subtree that consists of its offspring and their offspring, etc. This implies that any node can function as a tree on its own.

In addition, a binary search tree (BST) has the following two features:

1- Each node has a maximum of up to two children.

2-For each node, the values of its left descendent nodes are less than that of the current node, which in turn is less than the right descendent nodes (if any).

$159.24 is the balance after 9 months is the answer that you seek

Step-by-step explanation:

Answer:

the savings plan balance after 9 months with an APR of 8% and monthly payments of $250 is approximately $2,366.98.

Step-by-step explanation:

To find the savings plan balance after 9 months with an APR of 8% and monthly payments of $250, we can use the formula for the future value of an annuity:

FV = Pmt x ((1 + r/n)^(n x t) - 1) / (r/n)

where:

FV = future value

Pmt = monthly payment

r = annual interest rate

n = number of compounding periods per year

t = time in years

In this case, we have:

Pmt = $250

r = 8%

n = 12 (since payments are made monthly)

t = 9/12 = 0.75 (since 9 months is three-quarters of a year)

Substituting these values into the formula, we get:

FV = $250 x ((1 + 0.08/12)^(12 x 0.75) - 1) / (0.08/12)

FV ≈ $2,366.98

Therefore, the savings plan balance after 9 months with an APR of 8% and monthly payments of $250 is approximately $2,366.98.

The probability that it weighs more than 51 pounds exactly 53 pounds.

Given that, mean weight of 50 pounds and a standard deviation of 0.5 pounds.

We need to find the probability that it weighs more than 51 pounds,

P(X = 53) = 0

z = (51 - 50) / 0.5 = 2.00

P(X > 51) = P(z > 2.00) = 0.0228

z1 = (49 - 50) / 0.5 = -2.00

z2 = (51 - 50) / 0.5 = 2.00

P(49 < X < 51) = P(-2.00 < z < 2.00) = P(z < 2.00) - P(z < -2.00) = 0.9772 - 0.0228 = 0.9544

Hence, the probability that it weighs more than 51 pounds exactly 53 pounds.
