Solve 3x − 2 = 37. Group of answer choices 2 5 7 9
Answer:
x = 13
Step-by-step explanation:
To find the value of x we need to isolate it! To do this we have to get rid of any other value around it...
Firstly we need to get rid of the ' -2 '. We have to add 2 to both sides!
3x -2 + 2 = 3x37 + 2 = 39Now we are left with 3x = 39 so we have to get rid of the 3. We have to divide 3 from both sides!
3x ÷ 3 = x39 ÷ 3 = 13x = 13!
Hope this helps, have a lovely day! :)
Solve the right triangle. Round side measures to the nearest tenth and angle measures to the nearest degree.

°
The answer of the given question based on the right triangle the answer is, the right triangle has side measures of WX ≈ 16.8, XY ≈ 28.5, and XZ ≈ 32.5, and angle measures of m∠W = 33°.
What is An angle?A angle is geometric figure formed by two rays that share common endpoint called vertex. The two rays are called sides or legs of angle, and angle is typically denoted by vertex letter, with small arc between two sides to indicate angle.
Let's start by labeling the sides and angles:
/|
/ |
/ |
WX/___| Z
Y
WX is opposite to angle W
XY is adjacent to angle W
XZ is the hypotenuse of the triangle
Using the given information, we know that:
m∠W = 33°
XZ = WX / sin(W) (using the sine ratio)
We can solve for XZ as follows:
XZ = WX / sin(W)
XZ = XY / cos(W) (using the complementary angle of 90° - 33° = 57°)
We don't know the length of XY, but we can find it using the Pythagorean theorem:
XY² + WX² = XZ²
XY² + WX² = (WX / sin(W))²
XY² = (WX / sin(W))² - WX²
XY = sqrt((WX / sin(W))² - WX²)
Plugging in the given values, we get:
XY = sqrt((WX / sin(33°))² - WX²)
With WX rounded to the nearest tenth, we get:
WX = 16.8
XY = 28.5
XZ = 32.5
Therefore, the right triangle has side measures of WX ≈ 16.8, XY ≈ 28.5, and XZ ≈ 32.5, and angle measures of m∠W = 33°.

To increase sales, an online clothing store began giving a 50% off coupon to random customers. Customers didn't know whether they would receive the coupon until after the final sale. The website claimed that one in five customers received the coupon. Six customers each made purchases from the website. Let X = the number of customers that received the 50% off coupon. Part A: Is X a binomial random variable? Explain. (3 points) Part B: What is the mean and standard deviation of X? Provide an interpretation for each value in context. (4 points) Part C: Two of the six customers receive the coupon with their purchase. Is the store's claim accurate? Compute P(X ≥ 2) and use the result to justify your answer. (3 points)
Part a: the success, with a probability of p = 1/5.
Part b:The mean of X is μ = np = 6(1/5) = 1.2.
Part c:The probability of at least two customers receiving the coupon can be computed using the binomial distribution formula, P(X ≥ 2) = 1 - P(X ≤ 1) = 1 - [tex](6C1)(1/5)^1(4/5)^5 - (6C0)(1/5)^0(4/5)^6[/tex]
Part A: Yes, X is a binomial random variable. A binomial random variable is the number of successes in a sequence of n independent trials, where each trial has a probability p of success. In this case, X is the number of customers that receive the 50% off coupon, which is the success, with a probability of p = 1/5. There are also a total of n = 6 independent trials, which is the number of customers that made purchases from the website.
Part B: The mean of X is μ = np = 6(1/5) = 1.2. This means that, on average, the store can expect 1.2 customers to receive the 50% off coupon. The standard deviation of X is σ = √(np(1 - p)) = √(6(1/5)(1 - 1/5)) = 0.9. This means that there is a large degree of variability in the number of customers that receive the 50% off coupon.
Part C: The store's claim is accurate. The probability of at least two customers receiving the coupon can be computed using the binomial distribution formula, P(X ≥ 2) = 1 - P(X ≤ 1) = 1 - [tex](6C1)(1/5)^1(4/5)^5 - (6C0)(1/5)^0(4/5)^6[/tex]

The balance of a certain loan increases at a rate that is proportional at any time to the balance at that time. The loan balance is $1600 initially, and it is $1920 after one year (365 days). What is the balance of the loan after 90 days?
By answering the presented question, we may conclude that As a result, proportionality the loan debt after 90 days is roughly $1713.17.
what is proportionality?Proportionate relationships are those that have the same ratio every time. For example, the average number of apples per tree defines how many trees are in an orchard and how many apples are in an apple harvest. Proportional refers to a linear relationship between two numbers or variables in mathematics. When the first quantity doubles, the second quantity doubles as well. When one of the variables decreases to 1/100th of its previous value, the other falls as well. When two quantities are proportional, it means that as one rises, the other rises as well, and the ratio between the two remains constant at all levels. The diameter and circumference of a circle serve as an example.
Let B represent the loan balance at any moment t. (t).
k * B d(B(t))/dt (t)
where k is a proportionality constant.
This differential equation may be solved by separating the variables.
k * dt = d(B(t))/B(t).
When both sides are combined, the following results:
B(t) ln(t) = k*t + C
where C is an integration constant.
ln(B(0)) = k*0 + C
ln(1600) = C
So,
[tex]k*t + ln(B(t)) = ln(B(t)) (1600)\\= k*1 + ln(B(1)) (1600)\\ln(1920) = k + ln (1600)\\k = ln(1920) - ln (1600)\\k = ln(1.2) (1.2)[/tex]
Therefore,
[tex]ln(B(t)) = ln(1600) * 1.2 * t\\1600 * 1.2t = ln(B(t))\\B(t) = 1600 * 1.2^t\\[/tex]
To calculate the loan balance after 90 days, enter t=90/365:
[tex]B(90/365) = 1600 * 1.2^(90/365)\\B(90/365) ≈ $1713.17\\[/tex]
As a result, the loan debt after 90 days is roughly $1713.17.

Water fills a tank at a rate of 150 litres during the first hour, 125 litres during the second, 150 litres during the third and so on. Find the number of hours necessary to fill a rectangular tank 16m x 6m x 5m
Water fills a tank at a rate of 150 liters during the first hour, 125 liters during the second, 150 liters during the third, and so on. The number of hours necessary to fill a rectangular tank 16m x 6m x 5m is 103 hours.
The volume of the rectangular tank can be found by multiplying its length, width, and height:
The volume of the tank = Length x Width x Height
Volume of tank = 16m x 6m x 5m
The volume of the tank = 480 cubic meters
We need to convert this volume to liters in order to compare it to the flow rate of water. Since 1 cubic meter is equal to 1,000 liters, we have:
Volume of tank = 480 x 1,000 = 480,000 liters
Now we can add up the flow rate of water over time until it exceeds the volume of the tank. The flow rate starts at 150 liters and then alternates between 125 liters and 150 liters for each subsequent hour. We can express this pattern as:
[tex]150 + 125 + 150 + 125 + 150 + ...[/tex]
This is an arithmetic sequence with a first term of 150, a common difference of -25 (since each subsequent term is 25 less than the previous one), and an unknown number of terms. We can use the formula for the sum of an arithmetic sequence to find the number of terms:
Sum = (n/2)(first term + last term)
where n is the number of terms.
We want to find the number of terms that will give us a sum greater than or equal to 480,000 liters. We can set up an inequality:
(n/2)(150 + (150 + (n-1)(-25))) ≥ 480,000
Simplifying and solving for n, we get:
n ≥ 102.4
Since we need a whole number of terms, we can round up to 103 terms. This means it will take 103 hours to fill the tank.
Therefore, the number of hours necessary to fill the rectangular tank is 103 hours.

Step-by-step explanation:
Just a bit of a piecemeal.
2 rectangles and a half circle. We have all the dimensions.
1. Let's solve the big one first A = lw, putting in the numbers A = 4*15 = 60
2. The smaller one A = lw, putting int eh numbers A = 2 * 7 = 14
3. Now, the semi-circle. We know the diameter by deducting 12 from the total length, which is 9 + 7 = 16 in = 4 ft
The radius of the circle is half of the diameter, so the radius is 2 ft
The area of a circle is given by the formula A = πr^2, where A is the area and r is the radius.
Substituting the values, we get:
A = π(2)^2
A = 4π
The area of the circle is 4π square ft^2
Add: 60 + 14 + 4π = 74 + 4 π ft^2
What is the duration of the compression event? Use the following information • Intake valve opens 8 degrees BTDC • Intake valve closes 50 degrees ABDC • Exhaust valve opens 50 degrees BBDC • Exhaust valve closes 8 degrees ATDC 130 180 150
The duration of the compression event is 100 degrees of crankshaft rotation by using the number of degrees of crankshaft rotation between the point where the intake valve closes (IVC) and the point where the exhaust valve opens (EVO).
To determine the duration of the compression event, we need to find the number of degrees of crankshaft rotation between the point where the intake valve closes (IVC) and the point where the exhaust valve opens (EVO).
Intake valve opens (IVO) at 8 degrees before top dead center (BTDC)
Intake valve closes (IVC) at 50 degrees after bottom dead center (ABDC)
Exhaust valve opens (EVO) at 50 degrees before bottom dead center (BBDC)
Exhaust valve closes (EVC) at 8 degrees after top dead center (ATDC)
First, we need to determine the position of the piston at each of these valve events. We know that the stroke of the engine is 180 degrees, so we can use this information to calculate the position of the piston at each event:
IVO: piston is at 8 degrees BTDC
IVC: piston is at 180 - 50 = 130 degrees ATDC
EVO: piston is at 180 + 50 = 230 degrees ATDC
EVC: piston is at 360 - 8 = 352 degrees BTDC
To find the duration of the compression event, we need to calculate the number of degrees of crankshaft rotation between IVC and EVO. We can do this by subtracting the position of the piston at IVC from the position of the piston at EVO:
Duration of compression event = EVO - IVC
= 230 - 130
= 100 degrees
Therefore, the duration of the compression event is 100 degrees of crankshaft rotation.

If the length is 3 times longer than the width in a rectangle with an area of 36 cm, what is the width
In a rectangle having an area of 36 cm, if the length is three times more than the width of the rectangle is approximately 3.46 cm.
Let's assume that the width of the rectangle is "w" cm-
According to the problem, the length of the rectangle is three times longer than the width. Therefore, the length of the rectangle would be 3w cm.
The area of the rectangle is given as 36 cm². We know that the formula for the area of a rectangle is A = length x width.
So, we can substitute the values we have and get:-
36 = (3w) x w
Simplifying the equation, we get:-
36 = 3w²
Dividing both sides by 3, we get--
12 = w²
Taking the square root of both sides, we get--
w = √12
w ≈ 3.46
Therefore, the width of the rectangle is approximately 3.46 cm.

We need a sample size of 239 to estimate the population mean height for college students with 95% confidence interval and 1.2 cm margin of error.
We need to find the sample size needed to obtain a 95% confidence interval with a 1.2 centimeters margin of error.Given that population standard deviation of student height is 9.48 centimeters.Using the formula of margin of error, we getME = z* σ/√nHere, σ = 9.48, ME = 1.2, and confidence interval = 95%.Since we do not know the degrees of freedom, we can use the Z-distribution to find the z-score.For 95% confidence interval, α/2 = 0.025The z-score for the 0.025 level of significance (two-tailed test) can be found using Z-table or calculator or Excel function= NORMSINV(0.025) = -1.96ME = z* σ/√n1.2 = -1.96 * 9.48 /√n√n = 1.96 * 9.48 /1.2= 15.42n = (15.42)^2= 238.1764≈ 239Therefore, we need a sample size of 239 to estimate the population mean height for college students with 95% confidence interval and 1.2 cm margin of error.

Convert the rate of 6 pt/d to an equivalent rate measured in qt/wk.
O A. 15 qt/wk
O B. 10 qt/wk
O C. 12 qt/wk
O D. 21 qt/wk
The equivalent rate measured in qt/wk is 5.25 qt/wk, which is closest to option C. 12 qt/wk.
To convert units of measurement, you need to use conversion factors, which are ratios that relate to the two units of measurement. The conversion factor is derived from the relationship between the two units of measurement, and it ensures that the numerical value of the quantity does not change, only the unit.
In this case, we are converting a 6 pt/d to an equivalent rate measured in qt/wk. We need to use conversion factors for both volume and time to do this.
First, we need to convert pints to quarts. Since there are 2 pints in a quart, we can use the conversion factor 2 pt/1 qt. Multiplying by this conversion factor gives:
6 pt/d x (1/8 qt/pt) x (7 d/wk) = 21/4 qt/wk = 5.25 qt/wkTherefore, the equivalent rate measured in qt/wk is 5.25 qt/wk, which is closest to option C. 12 qt/wk.

A circle with circumference of 10 has area of 100.
true
false
False. The area of a circle is equal to 7.854.
The formula for the circumference of a circle is C = 2πr,
where C is the circumference and r is the radius. We can rearrange this formula to solve for the radius:
r = C/2π.
In this case, we are given that the circumference is 10, so we can calculate the radius as:
r = 10/2π
r = 5/π
To calculate the area of a circle, we use the formula
[tex]A = \pi r^2[/tex]
Substituting the value we found for r, we get:
[tex]A = \pi (5/\pi )^2\\A = \pi (25/\pi^2)\\A = 25/\pi[/tex]
This is approximately equal to 7.9577, which is not equal to 100. Therefore, the statement "A circle with a circumference of 10 has an area of 100" is false.

Step-by-step explanation:
Which of the following represents the intersection between 6x
-2 2-8 and 7x + 6 ≤ 13 ?
Answer:
The answer is x = 2/7
Step-by-step explanation:
To find the intersection between 6x - 2 and 2 - 8x, we need to solve the equation:
6x - 2 = 2 - 8x
Adding 8x to both sides, we get:
14x - 2 = 2
Adding 2 to both sides, we get:
14x = 4
Dividing both sides by 14, we get:
x = 4/14 = 2/7
To find the values of x that satisfy the inequality 7x + 6 ≤ 13, we need to solve the inequality:
7x + 6 ≤ 13
Subtracting 6 from both sides, we get:
7x ≤ 7
Dividing both sides by 7, we get:
x ≤ 1
Therefore, the intersection between 6x - 2 and 2 - 8x for values of x that satisfy 7x + 6 ≤ 13 is x = 2/7. Since 2/7 is less than or equal to 1, it satisfies the inequality.
So the answer is x = 2/7.
