Answer:
Slope= 4
Step-by-step explanation:
When you start at (0, 0) and then go to (1, 4), then you have to use the slope.
So, to figure out the slope, you have to do rise over run, rise/run.
So, as shown in the graph, the rise is 4 because the rise is the y so to get from 0 to 4, you have to add 4.
And the run, which would be the x side is 1 because to get from 0 to 1. You add 1.
This shows us that the slope is 4/1 which could be simplified to just 4.

can someone plz help me with this question: select the correct answer. what is √125 in simplest form?
Answer: First Option (5√5)
Answer:
First, you see if there are any perfect squares that are a factor of 125. If you do find some, find what is seemingly the biggest. In this case, it is 25, I think. So you can then out it as root(25×5), I think. As 25 is a perfect square, you can square and then put the number you get on the outside. So since 5×5=25, it becomes 5(root)5, which essentially means 5×(root)5, I think.
28 members;50% increase
Answer:
I think the answer is 42.
Step-by-step explanation:
If there is a 50% increase in members then the number of members would go up 14. Adding 14 to 28, you come away with 42.

If probability is greater than the level of significance then,
we should accept or reject null hypothesis?
Answer:
One of the most basic concepts in statistics is hypothesis testing. Not just in Data Science, Hypothesis testing is important in every field. Want to know how??? Let us take an example. You must have heard about lifebuoy?? Suppose
lifebuoy claims that, it kills 99.9% of germs. So how can they say so? There has to be a testing technique to prove this claim right?? So hypothesis testing uses to prove a claim or any assumptions.
Hopefully, this helps! :D

Step-by-step explanation:
I'm pretty sure this is the answer but it's been a while since I've done system of inequalities. Essentially the value and number of dimes is less than the value and number of quarters. And the value of both is less than or equal to 2 dollars
2. Write an equation in slope intercept form with the given Information Goes through points (1, 8) and (5, 0)
Answer:

Step-by-step explanation:
Slope: [tex]m = \frac{y_{2}-y_{1} }{x_{2}-x_{1}}[/tex]
Slope-Intercept Form: [tex]y=mx+b[/tex]
[tex]m=\frac{8-0}{1-5}[/tex]
[tex]m = -2[/tex]
[tex]y = -2x + b[/tex]
[tex]0 = -2 (5)+b[/tex]
[tex]0=(-10)+b[/tex]

Carter stated that 5(x + 9) - 3x is the same as 2x + 45. Lori disagreed with him and said that an equivalent expression is 2x + 9. Who was right?
Answer:
Carter;
5 ( x + 9 ) - 3x = 2x + 45
Step-by-step explanation:
Simplify the equation;
5 ( x + 9 ) - 3x
Distribute the 5, remember, you have to distribute 5 over both terms.
5x + 45 - 3x
Combine like terms;
2x + 45

Element X is a radioactive isotope such that its mass decreases by 81% every year. If an experiment starts out with 490 grams of Element X, write a function to represent the mass of the sample after tt years, where the daily rate of change can be found from a constant in the function. Round all coefficients in the function to four decimal places. Also, determine the percentage rate of change per day, to the nearest hundredth of a percent.
Answer:
We can say we start with 490 grams and after 1 year we have (490 * .81 grams) or 396.9 grams.
We can solve for half-life by this equation:
Half life = (time * log 2) / log (beginning amount / ending amount)
Half-life = (1 year * 0.30102999566) / log (490 / 396.9)
Half life = (1 year * 0.30102999566) / log (1.2345679012 )
Half life = (0.30102999566) / 0.091514981109
Half-Life = 3.2894067399 years
Well, that's a start.
Step-by-step explanation:
The half life of the given radioactive isotope will be 3.2894067399 years.
What is Half life period?
The amount of time it takes to disintegrate by half an initial amount. For a given reaction, a reactant's half-life t-1/2 is the time it takes for its concentration to reach a value which is the arithmetic mean of its initial and final value.
Here, Element X starts with 490 grams
After 1 year we have (490 X 0.81 grams) or 396.9 grams
Now, We can solve for half-life by this equation:
Half life = (time X log 2) / log (beginning amount / ending amount)
Half-life = (1 year X 0.30102999566) / log (490 / 396.9)
Half life = (1 year X 0.30102999566) / log (1.2345679012 )
Half life = (0.30102999566) / 0.091514981109
Half-Life = 3.2894067399 years
Thus, the half life of the given radioactive isotope will be 3.2894067399 years.

Solve for x using the vertical angles below:
(2 + 3x)
62
Answer:
20
Step-by-step explanation:
Solving for x using the vertical angles we get , the value of x is: x = 20.
Here, we have,
from the given figure we get,
angle (2 + 3x) and angle62 are opposite angles.
we know that,
When two lines intersect each other, then the opposite angles, formed due to intersection are called vertical angles or vertically opposite angles. A pair of vertically opposite angles are always equal to each other.
so, we have,
angle (2 + 3x) = angle62
(2 + 3x) = 62
or, 3x = 60
or, x = 20
Hence, Solving for x using the vertical angles we get , the value of x is: x = 20.

Answer:
I don't know how to answer question 1, but the answer from question 2 is x=5
Step-by-step explanation:
The triangle shown is an isosceles triangle because it has two congruent sides. The base angles of isosceles triangles are congruent so ∠y=∠x. since the ∠x is 52 the ∠y is also 52. We subtract the measure of angles x and y in order to find the measure of the third angle. 180-(52+52) or 180-104 is 76. this means that 14x=6=76. All we have to do to get the answer now is solve. 76-6 is 70 and 70 divided by 14 is 5. x=5.
The overhead reach distances of adult females are normally distributed with a mean of 205.5 and a standard deviation of 8.6 . a. Find the probability that an individual distance is greater than 218.00 cm. b. Find the probability that the mean for 15 randomly selected distances is greater than 204.00 c. Why can the normal distribution be used in part (b), even though the sample size does not exceed 30?
Answer:
a) 0.073044
b) 0.75033
c) The normal distribution can be used in part (b), even though the sample size does not exceed 30 because initial population size is been distributed normally , therefore, the mean of the samples will be normally distributed regardless of their size(meaning whether the sample size is less than or equal to or exceeds 30, the sample means the mean of the samples will be normally distributed regardless of their size).
Step-by-step explanation:
The overhead reach distances of adult females are normally distributed with a mean of 205.5 and a standard deviation of 8.6 .
a. Find the probability that an individual distance is greater than 218.00 cm.
We solve using z score formula
z = (x-μ)/σ, where
x is the raw score = 218
μ is the population mean = 205.5
σ is the population standard deviation = 8.6
For x > 218
z = 218 - 205.5/8.6
z = 1.45349
Probability value from Z-Table:
P(x<218) = 0.92696
P(x>218) = 1 - P(x<218) = 0.073044
b. Find the probability that the mean for 15 randomly selected distances is greater than 204.00
When = random number of samples is given, we solve using this z score formula
z = (x-μ)/σ/√n
where
x is the raw score = 204
μ is the population mean = 205.5
σ is the population standard deviation = 8.6
n = 15
For x > 204
Hence
z = 204 - 205.5/8.6/√15
z = -0.67552
Probability value from Z-Table:
P(x<204) = 0.24967
P(x>204) = 1 - P(x<204) = 0.75033
c. Why can the normal distribution be used in part (b), even though the sample size does not exceed 30?
The normal distribution can be used in part (b), even though the sample size does not exceed 30 because initial population size is been distributed normally , therefore, the mean of the samples will be normally distributed regardless of their size(meaning whether the sample size is less than or equal to or exceeds 30, the sample means the mean of the samples will be normally distributed regardless of their size).
