What is the conversion of 15 cm to inch ?
The value of centimeter to inches is converted by the conversion factor of 2.54 so 15 cm is 5.9 inches.
The conversion factor of 0.393701 can be used to change a measurement from centimetres (cm) to inches (in). To find the number of inches, multiply the number of centimetres by 0.393701. In this instance, 11.42 inches are equal to 29 cm multiplied by 0.393701.
It's crucial to remember that this conversion is based on the International System of Units (SI), and it could not be the same in other measurement systems. Also, it is important to remember that centimetres (cm) and inches (in) are units of measurement for length and not for other types of measures like mass, area, or volume.
Use the proper unit of measurement for the activity or the environment; failing to do so could result in mistakes and inaccurate results. Also, it's crucial to ensure that the measurements are taken on the same scale, as doing otherwise could result in inaccurate conversions. While inches are primarily utilised in the United States and the United Kingdom, centimetres are extensively used across the rest of the world.
When determining smaller lengths or widths, such as for clothing or paper size measurements, this conversion is frequently used.

Wendell is working with the equation y=1.6^(x-1)+20 in a science class that represents the growth of a certain population of bacteria. Wendell could insert a 11 into this equation and get an answer of 129.95. So Wendell knows that after 11 days there would be a population of about 129.95 bacteria. Wendell would really love an equation that tells him the reverse of this (the inverse). Meaning Wendell could put a 129.95 into the equation and get 11 out as the answer. Create the inverse function and explain everything that you did to create this. If you simply give the correct answer without any explanation it will be marked incorrect. Three hints: It has something to do with logs. A graphical approach to this would be to graph the original, ask yourself how the "minus 1" and "plus 20" shifted the graph, and then think about how the inverse needs to adjust. An algebraic approach would be to swap the x and y values of the original and go from there. Either way, check your answer when you're done!
The inverse function of the given function which gives the value of the number of days when the population of bacteria is known is:
f ⁻¹(x) = log₁.₆(1.6x - 32)
What is an inverse function?
A function takes in values, applies specific operations to them, and produces an output. The inverse function acts, agrees with the outcome, and returns to the initial function. The output of a function is returned by the inverse function, which also returns the initial value. A function that can reverse into another function is known as an inverse function or anti function. In other words, the inverse of a function "f" will take y to x if any function "f" takes x to y.
The given function is:
[tex]f(x) = 1.6^{x-1} + 20\\[/tex]
[tex]y = 1.6^{x-1} + 20\\[/tex]
Now we are asked to find the inverse of this function.
That is, we have to write x in terms of y.
And then substitute the y back with x, to write as an inverse function
f ⁻¹(x).
[tex]y = 1.6^{x-1} + 20\\[/tex]
y - 20 = [tex]1.6^{x-1}[/tex]
y-20 = 1.6ˣ / 1.6
1.6y - 1.6 * 20 = 1.6ˣ
1.6y - 32 = 1.6ˣ
x = log₁.₆(1.6y - 32)
Therefore the inverse function of the given function which gives the value of the number of days when the population of bacteria is known is:
f ⁻¹(x) = log₁.₆(1.6x - 32)

what information can the chi‑square goodness‑of‑fit test provide?
The chi-square goodness-of-fit test can provide important information about whether the observed data significantly deviates from the expected distribution, which categories or bins contribute to the deviation, and the overall goodness-of-fit of the data to the expected distribution.
The chi-square goodness-of-fit test is a statistical test used to determine if a sample of data comes from a population with a specific distribution. Specifically, the test compares the observed frequencies of data in different categories or bins with the expected frequencies of data in those categories based on a hypothesized distribution.
It can determine whether the observed data significantly deviates from the expected distribution. If the test results in a p-value less than the chosen level of significance, it indicates that the observed data significantly deviates from the expected distribution, and the null hypothesis (that the data follows the expected distribution) can be rejected.
It can identify which categories or bins contribute the most to any significant deviation. The test statistic and associated p-value can help to identify which categories or bins show significant differences between the observed and expected frequencies.
It can provide information on the overall goodness-of-fit of the data to the expected distribution. The test statistic provides a measure of the overall goodness-of-fit, with higher values indicating greater deviation from the expected distribution.

MaryAnn is printing photos from her recent trip to Europe. An online print shop charges $0.15 per 4x6-inch print, along with a $3.00 fee shipping charge. If MaryAnn has $35 to spend, how many prints can she order?
MaryAnn can order a total of 213 prints for cost $35, including shipping.
Each print costs $0.15, so MaryAnn can order $35/$0.15 = 233.33 prints, but since she can only order whole prints, she can order a maximum of 233 prints.
The shipping charge is a flat fee of $3.00 per order, regardless of how many prints MaryAnn orders.
Let's say MaryAnn orders x prints, then her total cost would be:
Cost = $0.15 x + $3.00
Since her total cost can't exceed her budget of $35, we can set up the following inequality:
$0.15 x + $3.00 ≤ $35.00
Subtracting $3.00 from both sides, we get:
$0.15 x ≤ $32.00
Dividing both sides by $0.15, we get:
x ≤ 213.33
Since MaryAnn can only order whole prints, she can order a maximum of 213 prints.

ABKR is shown, where D, P, and H are the midpoints
and the perimeter of ADPH is 23.5. DP = 17x,
PH = (6x + 5), and HD = 20x - 3.
Now that we know the value of x, we can find the values of DP, PH, and HD:
DP = 17x = 17(0.295) = 5.015
PH = 6x + 5 = 6(0.295) + 5 = 6.77
HD = 20x - 3 = 20(0.295) - 3 = 2.9
Therefore, DP ≈ 5.015, PH ≈ 6.77, and HD ≈ 2.9.
How is perimeter defined in math?The perimeter of a form is its edge's radius. Learn how to multiply the lengths of a shape's sides to determine its perimeter.
To solve this problem, we need to use the fact that the perimeter of ADPH is 23.5. We know that AD = DP + HD, and we also know the values of DP, PH, and HD in terms of x. So, we can set up an equation using these values and solve for x.
AD = DP + HD
AD = 17x + (20x - 3)
AD = 37x - 3
Perimeter of ADPH = AD + DP + PH + HD
23.5 = (37x - 3) + 17x + (6x + 5) + (20x - 3)
Simplifying the above equation, we get:
23.5 = 80x - 1
Solving for x, we get:
x = 0.295
Now that we know the value of x, we can find the values of DP, PH, and HD:
DP = 17x = 17(0.295) = 5.015
PH = 6x + 5 = 6(0.295) + 5 = 6.77
HD = 20x - 3 = 20(0.295) - 3 = 2.9

I say True to the Increasing from minute to 25 because Clayton’s time starts at 0 and the time increases to 25 minutes.
I say True because if you see the point where it shows 25 minutes and stops at 60 minutes until Clayton goes back up, it shows the line regularly occurring which would make him be constantly moving to 60 minutes. (Constant means to regularly occur)

Oy = 3x - 6
Oy=-3x + 6
O y = 1/3 x + 1
Oy=1/3x -1
Answer:
y = - 3x + 6
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
given
x - 3y = 3 ( subtract x from both sides )
- 3y = - x + 3 ( divide through by - 3 )
y = [tex]\frac{1}{3}[/tex] x - 1 ← in slope- intercept form
with slope m = [tex]\frac{1}{3}[/tex]
given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{\frac{1}{3} }[/tex] = - 3 , then
y = - 3x + c ← is the partial equation
to find c substitute (5, - 9 ) into the partial equation
- 9 = - 3(5) + c = - 15 + c ( add 15 to both sides )
6 = c
y = - 3x + 6 ← equation of perpendicular line

MARK ME AS BRAINILIST
Answer:
x=14°
z= 74°
Step-by-step explanation:
Here
(10x-34)°= 106°
since the Vertically Opposite Angle are equal.
so solving for it.
First, we can add 34° to both sides of the equation to get:
10x° - 34°+ 34° = 106° + 34°
Simplifying the left side gives:
10x° = 140°
Then we can divide both sides of the equation by 10 to get:
x = 14°
Again
z+106°=180°
since the sum of angle in the linear pair is equal to 180°
solving for it
we can subtract 106° from both sides of the equation to get:
z + 106° - 106° = 180° - 106°
Simplifying the left side gives:
z = 74°

(32°C × 9/5) + 32
= ( 288 / 5 ) + 32
= ( 57.6 ) + 32
= 89.6°F
Therefore, the converted value from Celsius to Fahrenheit for the given 32 Celsius is given by 89.6 Fahrenheit.

What is fraction?A fraction is a way of representing a part of a whole or a ratio between two quantities. It is written as two numbers, one above the other, with a horizontal line separating them. The number above the line is called the numerator and the number below the line is called the denominator. For example, the fraction 3/4 represents three parts out of four equal parts, or the ratio of three to four. Fractions can be used to represent a wide range of values, including numbers between whole numbers (such as 1/2 or 3/5), ratios between quantities (such as 2/3 cups of flour to 1 cup of sugar), and percentages (such as 75/100, which is equivalent to 75%, or three-quarters). Fractions are an important concept in mathematics and are used in many different contexts, such as in cooking, measurement, and finance.
Here,
The expression E¹⁰ⁿ=1 8(1/4)ⁿ⁻¹ means we need to evaluate the sum of the expression 8(1/4)ⁿ⁻¹, as n ranges from 1 to 10.
To do this, we can simply substitute each value of n into the expression and add up the results. Here are the first few terms of the sum:
n = 1: 8(1/4)⁰ = 8
n = 2: 8(1/4)¹ = 2
n = 3: 8(1/4)² = 1/2
n = 4: 8(1/4)³= 1/8
We can continue this pattern for the remaining values of n, and then add up all the terms:
8 + 2 + 1/2 + 1/8 + ... + (1/4)⁹
To simplify this expression, we can use the formula for the sum of a geometric series:
S = a(1 - rⁿ) / (1 - r)
where S is the sum of the series, a is the first term, r is the common ratio, and n is the number of terms.
In this case, the first term is 8, the common ratio is 1/4, and there are 10 terms. So we can substitute these values into the formula to get:
S = 8(1 - (1/4)¹⁰) / (1 - 1/4)
S = 8(1 - 1/1048576) / (3/4)
S = 8(1048575/1048576) * (4/3)
S = 8 * (3495250/1048576)
S = 27

Randomization in an experiment is important because it ensures that the results achieved are accurate .
Randomization in an experiment refers to a random assignment of participants to the treatment in an experiment .
Randomizing the experiments can help you get the best cause-effect relationships among the variables. It helps in controlling the lurking variables . These variables can affect the results to be different from what they are supposed to be . Randomization prevents biases and makes the results fair.
For ensuring that the information obtained from the experiment is correct, A randomized experiment is perfect to help us .
Researchers control values of the explanatory variable with a randomization procedure. So, if we see a relationship between the explanatory variable and response variables, we can say that it is a causal one.
