Adding a number to the set such that the number is further away from the mean, will increase the SD. This is because the average distance of the numbers from the mean increases.
The Standard Deviation will increase if a new number is added to the collection that deviates more from the mean. This is due to an increase in the standard deviation of the numbers.
How the standard deviation is affected if a number is added to a set that is far away from the mean?The standard deviation demonstrates how widely things vary or diverge from the mean (mean, or expected value).
The Standard Deviation will vary if all terms in the set are multiplied or divided by the same number. The Standard Deviation will vary by the same amount.
The same number will likewise be changed for the mean. Imagine an animated, proportionate size growth for the spatter. There will be a change in the "measure of spread". The distance between each term and the mean doubles if every term is doubled, but the distance between each term also doubles, increasing the standard deviation. The Standard Deviation gets smaller if each word is divided by two.
In general, the Standard Deviation is decreased when a new number is added to the set that is extremely close to the mean. Visualize the paint spatter on the wall. Would the dispersion be more or smaller if we paint a droplet extremely near the center? – decrease because there are now relative to before more droplets at the center.

The height, h, of a plant (in inches) w weeks since it was planted is represented by the equations h=3w+3. How many weeks will it takes the plant to reach one foot.
Answer: 3 weeks
Step-by-step explanation:
We have to note firstly that 12 inches = 1 foot.
The equation given to represent the height in the question, h = 3w + 3.
The number of weeks that it will take the plant to reach one foot will then be:
h = 3w + 3
12 = 3w + 3
3w = 12 - 3
3w = 9
w = 9/3
w = 3
It'll take 3 weeks

Kalyan's present age is one third his mothers present age . If the mothers age was 5 times his age 6 years ago ,what are their present age
Current ages:
Let Kaylan's present age be x years
Since his age is a third of his mother's present age:
mother's age * (1/3) = Kaylan's age
mother's age * (1/3) = x
mother's age = 3x [multiplying both sides by 3]
Kaylan's mother's age would be 3x years
Their ages 6 years ago:
Kaylan's age: x-6 years
Mother's age: 3x-6 years
We are told that mother's age was 5 times Kaylan's age, 6 years ago. So,
5*(Kaylan's age 6 years ago) = (Mother's age 6 years ago)
replacing the values
5(x - 6) = 3x-6
5x - 30 = 3x-6
2x - 30 = -6 [subtracting 3x from both sides]
2x = 24 [adding 30 on both sides]
x = 12 [dividing both sides by 2]
Hence, x = 12
Kaylan's present age(x) = 12 years
Mother's present age(3x) = 3*12 = 36 years

Can you help me with this answer
Answer:
B and D are correct.
Step-by-step explanation:
To find the area of a rectangle, simply multiply its length by its width. In this case, the length of the rectangle is [tex]5[/tex] m and the width of the rectangle is [tex]3[/tex] m, so its area must be [tex]5*3=15[/tex] square meters.
To find the area of a triangle, divide the product of the triangle's base and height by [tex]2[/tex]. As an algebraic expression, that would be [tex]\frac{bh}{2}[/tex], where [tex]b[/tex] and [tex]h[/tex] are the triangle's base and height, respectively. In this case, [tex]b=6[/tex] and [tex]h=5[/tex], so the triangle's area is [tex]\frac{6*5}{2}=15[/tex] square meters.
Now, let's look at the statements.
A: The triangle's area is [tex]15[/tex] square meters, not [tex]30[/tex], so A is incorrect.
B: The rectangle's area is [tex]15[/tex] square meters and the triangle's area is also [tex]15[/tex] square meters. Because the two figures have the same areas, their areas are equal, so B is correct.
C: We've already established that the two figures have equal areas, so one can't have a greater area than the other. Therefore, C is incorrect.
D: The rectangle's area is indeed [tex]15[/tex] square meters, so D is correct.
Hope this helps!
Answer:
B is correct, and D is correct
if you multiply 3 times 5 you get 15 m which is the area for the rectangle, then you have to find the area for the triangle, which you would have to multiply 6 times 5 which you get 30, then divide 30 by 2, which would be 15!

Mr John leased two thousand fifty meter square of land from the city administration. He gave one eighth of his land to his brother. How many meters square did he have left?
Answer:
1793.75 m²
Step-by-step explanation:
Given that :
Total amount of land leased = 2050 m²
Fraction of land given to brother = 1/8
Amount of land given to brother :
1/8 * 2050 = 256.25 m²
Amount of land left :
2050 m² - 256.25 m²
= 1793.75 m²

Step-by-step explanation:
The constant of proportionality is the ratio between the two proportional variables in a directly proportional relationship. In this case, the variables are [tex]x[/tex] and [tex]y[/tex].
To find the constant of proportionality, all we have to do is divide any value of [tex]y[/tex] by its corresponding value of [tex]x[/tex]. Let's take the values in the first row of the table. We know that [tex]x=2[/tex] and [tex]y=12[/tex], so the constant of proportionality is [tex]\frac{y}{x}=\frac{12}{2} =6[/tex]. Hope this helps!
