Answer:
12/40, 15/40, 18/40
Step-by-step explanation:
1/4, 1/2 = 1/4, 2/4
Since, Three rational numbers cannot come in between 1/4 and 2/4, we multiply them with 10.
∴ 1/4 × 10 = 10/40
∴ 2/4 × 10 = 20/40
∴ Three rational numbers between 10/40 and 20/40 = 12/40, 15/40, 18/40
(You can add more numbers from between 10/40 and 20/40 if you need)
Simplify: [3(2a)3/2] 2
Answer:
2=18a
Step-by-step explanation:
For each of the following research scenarios, decide whether the design uses a related sample. If the design uses a related sample, identify whether it uses matched subjects or repeated measures. (Note: Researchers can match subjects by matching particular characteristics, or, in some cases, matched subjects are naturally paired, such as siblings or married couples.) Lorrin Koran has studied whether antidepressants are effective for treating kleptomania. Suppose that people with kleptomania typically score 72 on the Barratt Impulsiveness Scale. You want to see whether kleptomaniacs who are taking antidepressants score lower on the impulsiveness scale than the population average. The design described . You are interested in a potential treatment for compulsive hoarding. You treat a group of 50 compulsive hoarders and compare their scores on the Hoarding Severity Scale before and after the treatment. You want to see if the treatment will lead to lower hoarding scores.
The design described ___________.
Therefore , the solution of the given problem of unitary method comes out to be , the same group of subjects are measured both before and after the treatment .
What is an unitary method?The data from this nanosection should be compound by two in order to complete the task using the unitary method. In essence, the marked by either a set or the pigment parts of the unit method are skipped when a desired object is present. For forty pens, a variable charge of Inr ($1.01) would be required. It's possible that one country will have total influence over the approach taken to accomplish this. Almost every living creature has a distinctive quality.
Here,
Due to the absence of a comparison group or before-and-after measurements, the first study scenario does not use a related sample.
In the second study scenario, the same group of subjects are measured both before and after the treatment using a related sample and repeated measurements.

Answer:
D.
Step-by-step explanation:
The last table is the correct choice. Because when you use the X method on the equation your answers from that is (m-8)(m-2).
Answer:
It's definitely D.
Step-by-step explanation:
It's D because it has a -2m and -8m if you add them you get the -10m in the equation the m2 is already there And if you multiply -2 * -8 you'll get 16 positive, because a negative plus a negative is a positive.
What is the conjugate of the fraction
Answer:
-10 + [tex]\sqrt{17}[/tex]
Step-by-step explanation:
the importance of the conjugate is, when multiplied by the numerator and denominator, to remove the radical
for example, if you multiply (-10 - [tex]\sqrt{17}[/tex]) by (-10 + [tex]\sqrt{17}[/tex]) by using the foil method you get:
100 - 10[tex]\sqrt{17}[/tex] + 10[tex]\sqrt{17}[/tex] - 17
the two middle terms drop out and you are left with 83 in the denominator

Jake has proved that a function, f(x), is a geometric sequence. How did he prove that?
Answer:
He showed that f(n) ÷ f(n - 1) was a constant ratio.
Given that Jake has proved that a function f(x) is a geometric sequence.
GEOMETRIC SEQUENCE: A geometric sequence is a sequence of numbers where each term is found by multiplying the preceding term by a constant called the common ratio, r.
So, in Jame's proof, he showed that each term is multiplied by a constant to get the next term.
That is, if 'c' is the constant that was used in the proof, then we must have
This implies that
Therefore, he showed that f(n) ÷ f(n - 1) was a constant ratio.

Paula is draining her fish tank.
When she starts draining it, the height of the water is 33 cm.
Six minutes later, the height of the water is 15 cm.
Question: If the water continues to drain
at this rate until it is empty, how many
total minutes will it take Paula to drain
her fish tank?
Answer:
If the water continues to drain at this rate, it would take 11 total minutes for Paula to drain her fish tank.
Step-by-step explanation:
In 6 minutes, she is able to drain 18 cms of her fish tank, so in 1 minute, she would be able to drain 3 cms of her fish tank. 15 divided by 3 is 5, so it would take 5 minutes to drain the rest of her fish tank. But it is asking for the total amount so 5 plus 6 is 11 total minutes.

Step-by-step explanation:
Given triangle is a right angle triangle;
Length of base = 2.5 unit
Length of perpendicular = 6 unit
Find:
The value of x
Computation:
Using Pythagoras theorem;
Hypotenuse² = Base² + Perpendicular²
Hypotenuse² = 2.5² + 6²
Hypotenuse² = 6.25 + 36
Hypotenuse² = 42.25
Hypotenuse = √42.25
Hypotenuse = 6.5 unit
The value of x = 6.5 units

If 3x + 10 = 10 + 2x, what is the value of x?
A) x = 4
B) x = -4
C) x = -1
D) x = 0
Answer:
x=0
Step-by-step explanation:
3x + 10 = 10 + 2x
Subtract 2x from each side
3x-2x + 10 = 10 + 2x-2x
x+10 = 10
Subtract 10 from each side
x+10-10 = 10-10
x=0
Answer:
x=0
Step-by-step explanation:
3x + 10 = 10 + 2x
Subtract 2x from each side
3x-2x + 10 = 10 + 2x-2x
x+10 = 10
Subtract 10 from each side
x+10-10 = 10-10
x=0
A study on the latest fad diet claimed that the amounts of weight lost by all people on this diet had a mean of 22.3 pounds and a standard deviation of 5.7 pounds. Step 2 of 2: If a sampling distribution is created using samples of the amounts of weight lost by 74 people on this diet, what would be the standard deviation of the sampling distribution of sample means
Answer:
The standard deviation of the sampling distribution of sample means would be of 0.6626 pounds.
Step-by-step explanation:
Central Limit Theorem
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
Standard deviation of 5.7 pounds.
This means that [tex]\sigma = 5.7[/tex]
If a sampling distribution is created using samples of the amounts of weight lost by 74 people on this diet, what would be the standard deviation of the sampling distribution of sample means?
Sample of 74 means that [tex]n = 74[/tex]
The standard deviaiton is:
[tex]s = \frac{\sigma}{\sqrt{n}} = \frac{5.7}{\sqrt{74}} = 0.6626[/tex]
The standard deviation of the sampling distribution of sample means would be of 0.6626 pounds.

I REALLY NEED HELP , “ a company is designing a new cylindrical water bottle. the volume of the bottle will be 207 cm *to the 3rd power* the height of the water bottle is 8.4 cm. what is the radius of the water bottle?”
Answer:
Radius, r = 2.80 cm
Step-by-step explanation:
Given the following data;
Volume of cylinder = 207 cm³
Height = 8.4 cm
Pie, π = 3.14
To find the radius of the water bottle;
Mathematically, the volume of a cylinder is given by the formula;
V = πr²h
Where;
V is the volume of a cylinder.
r represents the radius of the cylinder.
h represents the height of the cylinder.
Substituting into the formula, we have;
207 = 3.14 * r² * 8.4
207 = 26.376r²
r² = 207/26.376
r² = 7.85
r = √7.85
Radius, r = 2.80 cm
