is this a right triangle
Given triangle is not a right angle triangle.
What is Pythagoras theorem?
For any right angle triangle,
Hypotenuse ²= Base²+Height ²
To determine whether the any triangle is a right triangle, we can use the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.
Let's denote the sides of the triangle as follows,
a = 14
b = 10
c = 4√19
Then we can check whether the Pythagorean theorem holds for these values:
c² = (4√19)² = 16×19 = 304
a²+ b² = 14²+ 10² = 196 + 100 = 296
Since c² is not equal to a² + b², the triangle is not a right triangle. Therefore, the answer is no, the given triangle is not a right angle triangle.

Suppose a shipment of 400 components contains 68 defective and 332 non-defective computer components. From the shipment you take a random sample of 25. When sampling with replacement (so that the p = probability of success does not change), note that a success in this case is selecting a defective part. What is the probability of there being no defects in the entire shipment?
The probability of there being no defects in the entire shipment is 0.2075.
What is probability?
Probability can be used to calculate an event's probability. It can only be used to assess the possibility that an event will occur. A scale from 0 to 1, where 0 is impossible and 1 is a particular occurrence.
We are given that out of the 400 components, 68 are defective and 332 are non-defective computer components.
A random sample of 25 is taken.
So,
⇒ Probability (Defects in the shipment) = [tex]\frac{68}{400}[/tex]
⇒ Probability (Defects in the shipment) = 0.17
Thus,
⇒ Probability (No Defects in the shipment) =25 * (1 - 0.17)
⇒ Probability ( No Defects in the shipment) = 25 * (0.83)
⇒ Probability ( No Defects in the shipment) = 0.2075
Hence, the probability of there being no defects in the entire shipment is 0.2075.

What is the value of tan(-284°24') to the nearest ten-thousandth?
To find the value of tan(-284°24'), we can use the fact that the tangent function has period π, which means that:
tan(x) = tan(x + nπ)
where n is any integer. We can use this fact to convert the angle -284°24' to an equivalent angle between 0° and 360°:
-284°24' = -360° + 75°36' = 75°36'
Now, we need to find the reference angle, which is the acute angle between the terminal side of the angle and the x-axis. Since 75°36' is in the second quadrant (where the tangent function is positive), the reference angle is:
75°36' - 180° = -104°24'
Finally, we can use the identity:
tan(-θ) = -tan(θ)
to find the value of tan(-104°24'):
tan(-104°24') = -tan(104°24')
We can use a calculator to find that:
tan(104°24') ≈ 2.3835
Therefore:
tan(-284°24') ≈ -2.3835 (rounded to the nearest ten-thousandth)
So, the value of tan(-284°24') to the nearest ten-thousandth is -2.3835.

How much intresr will jackson have earned at the end of the 3 years?
Jackson will have earned $72 in interest at the end of 3 years.
How to solve for the interest earnedJackson saves $25 per month for 12 months:
$25 * 12 months = $300 per year
Now, let's calculate the total amount saved at the end of each year:
Year 1: $300
Year 2: $300 + $300 = $600
Year 3: $300 + $600 = $900
Next, we'll apply the 4% interest rate compounded annually to the final yearly balance:
Year 1: $300 * (1 + 0.04) = $300 * 1.04 = $312
Year 2: $600 * (1 + 0.04) = $600 * 1.04 = $624
Year 3: $900 * (1 + 0.04) = $900 * 1.04 = $936
So, the total amount Jackson will save at the end of 3 years is:
$312 (Year 1) + $624 (Year 2) + $936 (Year 3) = $1,872
Total deposited:
$300 + $600 + $900
= $1,800
Total interest earned:
$1,872 - $1,800
= $72

If 9/23 = 0.3913043478260869565217, what is the 999th digit to the right of the decimal?
The 999th digit to the right of the decimal point is 9.
Describe Decimal Expansion?Decimal expansion is the representation of a number in decimal form. In decimal expansion, a number is represented using the base-ten positional notation system, where each digit represents a multiple of a power of ten.
For example, the decimal expansion of the number 1234.5678 is:
which simplifies to:
1000 + 200 + 30 + 4 + 0.5 + 0.06 + 0.007 + 0.0008 = 1234.5678
The decimal expansion of a number can be finite or infinite, and it may or may not be a repeating decimal. A repeating decimal is a decimal that has a repeating pattern of digits after the decimal point. For example, the decimal expansion of 1/3 is 0.3333..., with the digit 3 repeating infinitely.
To find the 999th digit to the right of the decimal point, we need to determine the repeating block of digits in the decimal expansion of 9/23.
The remainder when 9 is divided by 23 is 9, so we can start the long division as follows:
0.3913043478260869565217...
--------------------------------
23 | 9.00000000000000000000
- 6
--------
30
-23
-----
7
...
We can see that the decimal expansion of 9/23 repeats after 22 digits, since the remainder becomes 7, which is the same as the remainder we obtained after dividing 9 by 23.
Therefore, the 999th digit to the right of the decimal point is the same as the (999 mod 22)th digit, which is the 9th digit in the repeating block of digits:
0.3913043478260869565217...
9
So the 999th digit to the right of the decimal point is 9.

a company finds it can produce 30 heaters for $7500 while producing 40 heaters cost $9000, express the cost y as a linear function of the number of heaters x
express the cost y as a a linear function of the numbers of heatrs x
Answer:
y = 150x + 3000
Step-by-step explanation:
We can express the cost (y) as a linear function of heater quantity (x) by writing the equation in the slope-intercept form (y = mx + b), where m is the slope (in this case change in cost / change in heater quantity) and b is the y-intercept (when x = 0).
To find the slope (m), we can use the slope formula, which is
[tex]m=\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex], where x1 and y1 are one point and x2 and y2 are the other point.
If we allow (30, 7500) to represent x1 and y1 and (40, 9000) to represent x2 and y2, our slope is:
[tex]m=\frac{9000-7500}{40-30}\\ \\m=\frac{1500}{10}\\ \\m=150[/tex]
Now, we can find the y-intercept by plugging in the slope and one of the points and solving for b:
[tex]7500=150(30)+b\\7500=4500+b\\3000=b[/tex]
Thus, our equation where y (cost) is a function of x (heater quantity) is y = 150x + 3000

You select a family with three children. If M represents a male child and F a female child, the set of equally likely outcomes for the children's genders is shown below. Find the probability of selecting
a family with at least two male children.
(MMM, MMF, MFM, MFF, FMM, FMF, FFM, FFF)
The probability of having at least two male children is
(Type an integer or a simplified fraction.)
There are 8 possible outcomes and we need to find the probability of having at least two male children.
Out of the 8 outcomes, there are 3 outcomes where all children are female (FFF, probability = 1/8) and 3 outcomes where there is exactly one male child (FMF, FFM, MFF, probability = 3/8).
Therefore, the probability of having at least two male children is the complement of these outcomes, which is 1 - (1/8 + 3/8) = 4/8 or 1/2.
So the probability of selecting a family with at least two male children is 1/2 or 0.5.
The probability of selecting a family with at least two male children is 3/8.
What is probability?It is the chance of an event to occur from a total number of outcomes.
The formula for probability is given as:
Probability = Number of required events / Total number of outcomes.
Example:
The probability of getting a head in tossing a coin.
P(H) = 1/2
We have,
There are 8 equally likely outcomes, and we want to find the probability of selecting a family with at least two male children.
There are three outcomes that satisfy this condition:
MMM, MMF, and MFM.
The probability of each of these outcomes is:
MMM: (1/2) x (1/2) x (1/2) = 1/8
MMF: (1/2) x (1/2) x (1/2) = 1/8
MFM: (1/2) x (1/2) x (1/2) = 1/8
So the total probability of selecting a family with at least two male children is:
1/8 + 1/8 + 1/8 = 3/8
Therefore,
The probability of selecting a family with at least two male children is 3/8.

Step-by-step explanation:
Ratio:Men : Women = 5 : 9
Number of men = 5x
Number of women = 9x
42 women left the museum.
Number of remaining women = 9x - 42
New ratio = 2 : 3
[tex]\dfrac{5x}{9x -42}=\dfrac{2}{3}\\\\\\\bf Cross \ multiply,[/tex]
3*5x = 2*(9x - 42)
15x = 2*9x - 2*42
15x = 18x - 84
18x - 84 = 15x
Add 84 to both the sides,
18x = 15x + 84
Subtract 15x from both sides,
18x - 15x = 84
3x = 84
Divide both sides by 3,
x = 84 ÷ 3
x = 28
Number of men = 5 * 28 = 140
Number of women = 9*28 = 252

A car was valued at $44,000 in the year 1992. The value depreciated to $15,000 by the year 2006.
A) What was the annual rate of change between 1992 and 2006?
r=---------------Round the rate of decrease to 4 decimal places.
B) What is the correct answer to part A written in percentage form?
r=---------------%
C) Assume that the car value continues to drop by the same percentage. What will the value be in the year 2009 ?
value = $ -----------------Round to the nearest 50 dollars.
The rate of change between 1992 and 2006 is a decrease of 8.39%.
EquationsTo find the annual rate of change between 1992 and 2006, we can use the formula:
r = [tex](V2/V1)^{1/n}[/tex] - 1
where V1 is the initial value, V2 is the final value, and n is the number of years between the two values.
r = -0.0839
Therefore, the annual rate of change between 1992 and 2006 is -0.0839.
To express the rate of change in percentage form, we can multiply the result from part A by 100:
r = -0.0839 x 100
r = -8.39%
Therefore, the rate of change between 1992 and 2006 is a decrease of 8.39%.
To find the value of the car in the year 2009, we can assume that the value continues to drop at the same percentage rate as calculated in part A.
From 2006 to 2009, there are 3 years. So, using the formula for exponential decay, we have:
where V0 is the value in 2006, r is the rate of decrease, and n is the number of years between 2006 and 2009.
V = 11792.51
Therefore, the value of the car in the year 2009 would be approximately $11,800 (rounded to the nearest $50).

What is circumference?
The circumference of a circle or ellipse in geometry is its perimeter. That is, if the circle were opened up and straightened out to a line segment, the circumference would be the length of the arc. The curve length around any closed figure is more often referred to as the perimeter.
Here, we have
Given: A circular garden has a circumference of 40.25 feet.
We have to find the diameter of the garden.
The formula for the circumference of a circle is given as 2πr.
We have to find the radius of the circular garden
Hence: 2πr = 40.25m
π = 3.14
To find the radius, the formula would be given as
r = C/2π
Where C = Circumference of the circle
r = (40.25/2)x 3.14
r = 63.195
d = C/π
d = 40.25/3.14
d = 12.82
Hence, the approximate diameter of the garden is 12.82 feet.
