a. The hypotenuse of the right angled triangle is 8
b. The leg of the right angled triangle is 4√2
What is the hypotenuse of a right angled triangle?The hypotenuse of a right angled triangle is its longest side
a. Given the triangle in the figure we see that the longest side facing the right angle is 8.
So, the hypotenuse is 8.
b. To find the leg of the right angle triangle x, using the trigonometric ratio
sinФ = opposite/hypotenuse
= x/H
Making x subject of the formula, we have that
x = H sinФ
Given that
H = 8 and Ф = 45°Substituting the values of the variables into the equation, we have that
x = H sinФ
x = 8sin 45°
= 8 × 1/√2
= 8/√2
Rationalizing the denominator, we have that
x = 8/√2 × √2/√2
= 8 × √2/(√2)²
= 8√2/2
= 4√2
So, the leg is 4√2

for a math assignment, michelle rolls a set of three standard dice at the same time and notes the results of each trial. what is the total number of outcomes for each trial?
There are 216 possible outcomes for each trial of rolling three standard dice.
In probability theory, an outcome is defined as the result of a single experiment or trial. The total number of outcomes in a trial can be determined by the multiplication principle, which states that if there are m ways to do one thing, and n ways to do another, then there are m x n ways to do both.
In this case, Michelle is rolling three standard dice simultaneously, which means that there are six possible outcomes for each die. Therefore, the total number of outcomes for a single trial is calculated by multiplying the number of outcomes for each die. Using the multiplication principle, we get:
Number of outcomes for each die = 6
Total number of outcomes for a single trial = 6 x 6 x 6 = 216
It is important to note that not all outcomes are equally likely, and the probability of getting a specific outcome can be calculated by dividing the number of favorable outcomes by the total number of outcomes.

In a sample of 200 people, 150 said they would vote for Davis. What are the odds against Davis winning the election?
The requried odds against Davis winning the election is 0.33 or 33%.
We can find the odds against Davis winning the election by using the formula:
odds against Davis = (number of people not voting for Davis) / (number of people voting for Davis)
Out of the 200 people, 150 said they would vote for Davis. So the number of people not voting for Davis is:
200 - 150 = 50
Therefore, the odds against Davis winning the election are:
odds against Davis = 50 / 150 = 1/3 or 0.33 (rounded to two decimal places)
This means that for every person who thinks Davis will win, there are three people who think he will lose.

suppose that x is a normal random variable with mean 5. if p{x > 9} = .2, approximately what is var(x)?
suppose that x is a normal random variable with a mean of 5. if p{x > 9} = .2, So, the approximate variance of the normal random variable X is 22.66.
To find the variance of a normal random variable X with mean 5 and given P(X > 9) = 0.2, we will follow these steps:
1. Recognize that X follows a normal distribution: X ~ N(μ, σ²), where μ = 5 and σ² is the variance we want to find.
2. Convert the probability statement P(X > 9) = 0.2 to a standard normal distribution (Z) by finding the corresponding Z-score:
Z = (X - μ) / σ
3. Look up the Z-score that corresponds to the given probability (0.2) in a standard normal (Z) table. Since the table typically gives P(Z < z), we'll find P(Z < z) = 1 - 0.2 = 0.8. The corresponding Z-score is approximately 0.84.
4. Plug in the known values and solve for σ:
0.84 = (9 - 5) / σ
σ ≈ 4 / 0.84
σ ≈ 4.76
5. Finally, find the variance, which is σ²:
σ² ≈ 4.76²
σ² ≈ 22.66
So, the approximate variance of the normal random variable X is 22.66.

The approximate variance of the normal random variable X is the square of the standard deviation:
Var(X) ≈ [tex](4.76)^2[/tex] ≈ 22.65 (rounded to two decimal places).
To approximate the variance of the normal random variable X with a mean of 5, given that P(X > 9) = 0.2, we can use the z-score and standard normal distribution.
First, we calculate the z-score using the standard normal distribution formula:
z = (X - μ) / σ
where X is the value of interest (in this case, 9), μ is the mean (5), and σ is the standard deviation.
Plugging in the values, we get:
z = (9 - 5) / σ = 4 / σ
Next, we use the standard normal distribution table or a calculator to find the z-score that corresponds to a cumulative probability of 0.2. Let's assume that z = -0.84.
Now, we can use the z-score formula to solve for the standard deviation σ:
-0.84 = 4 / σ
Cross-multiplying, we get:
-0.84σ = 4
Dividing both sides by -0.84, we get:
σ ≈ 4 / -0.84 ≈ -4.76
Since the standard deviation cannot be negative, we discard the negative value and take the absolute value, resulting in:
σ ≈ 4.76

Determine the measure of the exterior angle in the diagram
The exterior angle in the figure is 10 degrees
How to find the exterior anglesIn a triangle, the sum of all angles is 180 degrees. So we can set up an equation with the given angles:
2x + 3x + (3x + 4) = 180
Simplifying the equation, we get:
8x + 4 = 180
8x = 176
x = 22
So the value of x is 22.
To find the measures of the angles, we can substitute this value of x into the given expressions:
The first angle is 2x, so it measures 2(22) = 44 degrees.
The second angle is 3x, so it measures 3(22) = 66 degrees.
The third angle is 3x + 4, so it measures 3(22) + 4 = 70 degrees.

You may round your answer to the nearest hundredth.
The expected count for the cell corresponding to petals whose length is more than 5.7 cm and whose width is more than 2 cm is approximately 7.67.
What is the frequency?
The number of periods or cycles per second is called frequency. The SI unit for frequency is the hertz (Hz). One hertz is the same as one cycle per second.
To find the expected count for the cell corresponding to petals whose length is more than 5.7 cm and whose width is more than 2 cm, we need to calculate the expected frequency for that cell using the formula:
Expected frequency = (row total * column total) / grand total
For this particular cell, the row total is 16 (from the table) and the column total is 23.
The grand total is 48 (also from the table). So, we can calculate the expected frequency as:
Expected frequency = (16 * 23) / 48 = 7.67
Rounding this to the nearest hundredth, we get the expected count as 7.67.
Therefore, the expected count for the cell corresponding to petals whose length is more than 5.7 cm and whose width is more than 2 cm is approximately 7.67.

What is number line?A number line is a diagram that depicts numbers on a straight line. It is a tool for comparing and sorting numbers. It can represent any real number, including whole numbers and natural numbers.
Jesse currently has 520 signatures and needs at least 1000 signatures, which means he still needs to collect 1000 - 520 = 480 signatures.
He has 6 more weeks to collect the signatures he needs, so he wants to collect the same number of signatures each week. Let's call this number x, representing the number of signatures he collects each week. Then, the total number of signatures he collects in the remaining 6 weeks would be 6x.
We want to find the range of values for x that would allow Jesse to collect at least 480 signatures in the remaining 6 weeks. In other words, we want to solve the inequality:

c) Calculate the interest due on January 11th and the balance of the loan after the January 11th pa payment.
d) Calculate the final payment (interest + principal) Peter must pay on the due date.
Please only serious answers
Answer:
A. February 26th
B. $3,500 - Balance ≈ $6,697.26
C. $2,500 - Balance ≈ $4,263.46
D. $4,284.81
Step-by-step explanation:
a) What is the due date of the loan?
The loan term is given as 317 days, and the loan starts on April 15th. To find the due date, we will add 317 days to April 15th.
April 15th + 317 days = April 15th + (365 days - 48 days) = April 15th + 1 year - 48 days
Subtracting 48 days from April 15th, we get:
Due date = February 26th (of the following year)
b) Calculate the interest due on October 12th and the balance of the loan after the October 12th payment.
First, we need to calculate the number of days between April 15th and October 12th:
April (15 days) + May (31 days) + June (30 days) + July (31 days) + August (31 days) + September (30 days) + October (12 days) = 180 days
Now, we will calculate the interest for 180 days:
Interest = Principal × Interest Rate × (Days Passed / 365)
Interest = $10,000 × 0.04 × (180 / 365)
Interest ≈ $197.26
Peter will make a payment of $3,500 on October 12th. So, we need to find the balance of the loan after this payment:
Balance = Principal + Interest - Payment
Balance = $10,000 + $197.26 - $3,500
Balance ≈ $6,697.26
c) Calculate the interest due on January 11th and the balance of the loan after the January 11th payment.
First, we need to calculate the number of days between October 12th and January 11th:
October (19 days) + November (30 days) + December (31 days) + January (11 days) = 91 days
Now, we will calculate the interest for 91 days:
Interest = Principal × Interest Rate × (Days Passed / 365)
Interest = $6,697.26 × 0.04 × (91 / 365)
Interest ≈ $66.20
Peter will make a payment of $2,500 on January 11th. So, we need to find the balance of the loan after this payment:
Balance = Principal + Interest - Payment
Balance = $6,697.26 + $66.20 - $2,500
Balance ≈ $4,263.46
d) Calculate the final payment (interest + principal) Peter must pay on the due date.
First, we need to calculate the number of days between January 11th and February 26th:
January (20 days) + February (26 days) = 46 days
Now, we will calculate the interest for 46 days:
Interest = Principal × Interest Rate × (Days Passed / 365)
Interest = $4,263.46 × 0.04 × (46 / 365)
Interest ≈ $21.35
Finally, we will calculate the final payment Peter must pay on the due date:
Final payment = Principal + Interest
Final payment = $4,263.46 + $21.35
Final payment ≈ $4,284.81

y = −72
x + 11
7x + 2y = 20
The solution to the system of equations is (23, -72).
How to find system of equations ?The first equation is y = -72, which means that whatever the value of x is, the value of y will always be -72.
Substituting y = -72 in the second equation, we get:
7x + 2(-72) = 20
Simplifying this equation, we get:
7x - 144 = 20
Adding 144 to both sides, we get:
7x = 164
Dividing both sides by 7, we get:
x = 23.428571...
So the solution to the system of equations is the ordered pair (x, y) = (23.428571..., -72).
However, we usually express solutions as ordered pairs of integers, so we can round x to the nearest integer to get:
(x, y) = (23, -72)

a single-subject study is testing an intervention to increase the number of bites of vegetables a child consumes at lunch. one subject, janelle, never took more than three bites during baseline. after the treatment, her percentage of nonoverlapping data (pnd) was 90%. what does this mean?
Janelle's intervention to increase vegetable consumption was successful and baseline period as her PND was 90%, indicating a positive outcome.
In a solitary subject review, the level of non-covering information (PND) is an action used to evaluate the viability of a mediation. It is determined by separating the quantity of examples wherein the mediation was compelling by the absolute number of occasions in which the way of behaving was noticed.
For this situation, the intercession was to expand the quantity of chomps of vegetables Janelle consumed at lunch.The PND worth of 90% actually intends that during the mediation stage, Janelle's way of behaving of taking multiple chomps of vegetables was noticed 90% of the time and that the intercession was effective in expanding her vegetable utilization.
This recommends that the intercession was viable for Janelle and can be utilized as proof to help the viability of the mediation for comparative cases. Nonetheless, it is essential to recreate the review with numerous subjects to approve the mediation's viability.

What is equation?An equation is a mathematical statement that states that two expressions are equal. It is typically written as a comparison between two expressions and consists of an equal sign (=). Equations are used to solve mathematical problems, to understand the relationships between different quantities, and to describe the behavior of a physical system. In addition, equations are used to calculate various quantities, such as the area of a circle or the speed of an object.
To show that cosh2x−sinh2x=1, we can use the identities for cosh2x and sinh2x. The identity for cosh2x is cosh2x=2cosh2x−1 and the identity for sinh2x is sinh2x=2sinh2x−1.
Substituting these identities into the equation cosh2x−sinh2x=1 yields 2cosh2x−1−2sinh2x−1=1. Simplifying this equation yields cosh2x−sinh2x=1, as required. Thus, we can conclude that cosh2x−sinh2x=1.

The correct form of question is Show that cosh2x−sinh2x=1 .
50 liter milk is consumed by 3 babies in 20 days if they got another baby how many milk is required for 25 days
If the three babies consume 50 liters of milk in 20 days, then 4 babies will consume 83 liters of milk in 25 days.
We can start by using the given information to calculate the daily milk consumption rate per baby. The total milk consumed over 20 days by the three babies is 50 liters. Therefore, the daily milk consumption rate per baby is:
Daily milk consumption rate per baby = 50 liters / (3 babies x 20 days) = 0.83 liters per day per baby
If we add another baby, the total number of babies becomes 4. We want to find out how much milk they will consume in 25 days. Total milk required for 4 babies in 25 days = (number of babies) x (daily milk consumption rate per baby) x (number of days)
Substituting the given values, we get:
Total milk required = 4 x 0.83 liters per day per baby x 25 days
Total milk required = 83 liters
As a result, if three babies drink 50 liters of milk in 20 days, four babies will drink 83 liters of milk in 25 days.
