Mean: 13
Median: 9
Mode: 9
Range: 28
The mean,median,mode and range of the data will be 13,9,9 and 28.
How to find the mean of a data set?Mean is the ratio of the sum of the values of the data set to the total number of values available in the data set.
Thus, we get;
[tex]\rm Mean = \dfrac{\text{Sum of the observations of the data set}}{\text{Total number of observations}}[/tex]
[tex]\rm Mean= \frac{3+25+9+30+9+2}{6} \\\\ Mean=13[/tex]
Arrange the data in the ascending order;
2,3,9,9,25,30
The median of the data set is;
[tex]\rm Median = \frac{9+9}{2} \\\\ Median =9[/tex]
Mode is the value appear most of the time in the data set;
9 is the number repeat two times in the data set.
Mode = 9
Range of the data is the difference of the maximum and the minimum value;
Range=30-2
Range=28
Hence,the mean,median,mode and range of the data will be 13,9,9 and 28.

What are the steps for solving 6x+2y=4
Answer:
X=4-2y/6
Y=4-6x/2
Step-by-step explanation:
For X:
1) -2y
Once you subtract 2y you are left with 6x=4-2y
2) Divide by 6 on both sides to get x alone
That would give you your answer of X=4-2y/6
For Y:
1) -6x
After subtracting 6x you would have 2y=4+6x
2) Like the steps above, you divide by 2 on both sides and that would give you your answer of Y=4-6x/2

investment A save £160 per month for 2 years. 2.5% interest is added to the total amount saved. Investment B invest £3800. Compound interest is added at 3% each year
Answer:
95.42
Step-by-step explanation:
Investment A:
160*24*1.025=3936
Investment B:
3800(1+.03)^2=4031.42
4031.42-3936= 95.42
Investment B is 95.42 more than investment A.
What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
Given,
investment A save £160 per month for 2 years.
2.5% interest is added to the total amount saved.
Investment A:
160×24×1.025=3936
Investment B:
Investment B invest 3800.
Compound interest is added at 3% each year
Convert 3% to decimal value by dividing 3 by 100.
3/100=0.03
P=A(1+r)t
A is initial deposit, r is rate of interest and t is time
3800(1+0.03)²
3800(1.03)²=3800×1.0609
=4031.42
We need to find how much investment B has more than investment A.
To find this let us find difference between investment A and investment B.
4031.42-3936= 95.42
Hence investment B is 95.42 more than investment A.

According to records, the amount of precipitation in a certain city on a November day has a mean of 0.10 inches, with a standard deviation of 0.07 inches. What is the probability that the mean daily precipitation will be 0.11 inches or less for a random sample of November days (taken over many years)?
Carry your intermediate computations to at least four decimal places. Round your answer to at least three decimal places.
Answer:
The probability that the mean daily precipitation will be 0.11 inches or less for a random sample of November days
P(X≤ 0.11) = 0.4404
Step-by-step explanation:
Step(i):-
Given that the mean of the Population = 0.10 inches
Given that the standard deviation of the population = 0.07inches
Let 'X' be a random variable in a normal distribution
[tex]Z = \frac{x-mean}{S.D} = \frac{0.11-0.10}{0.07} = 0.1428[/tex]
Step(ii):-
The probability that the mean daily precipitation will be 0.11 inches or less for a random sample of November days
P(X≤ 0.11) = P(Z≤0.1428)
= 1-P(Z≥0.1428)
= 1 - ( 0.5 +A(0.1428)
= 0.5 - A(0.1428)
= 0.5 -0.0596
= 0.4404
Final answer:-
The probability that the mean daily precipitation will be 0.11 inches or less for a random sample of November days
P(X≤ 0.11) = 0.4404

percent of 45.
Answer:
20%
Step-by-step explanation:
When asked, "x is what percent of y?" divide x by y and multiply by 100.
9/45 = 0.2
0.2 * 100 = 20%
Recall that we multiply by 100 to convert decimal to percent.
Step-by-step explanation:
Let x% of 45 be 9 Then
x % of 45 = 9
x / 100 * 45 = 9
45x = 900
x = 900 / 45
x = 20%

Write x² - 6x + 3 in the form (x-a)²+ b.
Answer:
(x + 3)² - 12
Step-by-step explanation:
x²+6x-3
= x²+ 6x + 9 - 12
= (x + 3)² - 12
The form of x² - 6x + 3 can be written as (x-3)² - 6.
What is a quadratic equation?A quadratic equation is the second-order degree algebraic expression in a variable. the standard form of this expression is ax² + bx + c = 0 where a. b are coefficients and x is the variable and c is a constant.
We are given that;
Equation= x² - 6x + 3
Now,
To write x² - 6x + 3 in the form (x-a)²+ b, we can use the method of completing the square. This involves adding and subtracting a constant term to make the expression a perfect square trinomial. Here are the steps:
Write x² - 6x + 3 as x² - 6x + ___ - ___ + 3, leaving two blanks for the constant term.
To find the constant term, divide the coefficient of x by 2 and square it. In this case, -6/2 = -3 and (-3)² = 9. So we fill in the blanks with 9 and get x² - 6x + 9 - 9 + 3.
Factor the first three terms as a perfect square: (x - 3)² - 9 + 3.
Simplify the last two terms: (x - 3)² - 6.
Compare with the form (x-a)²+ b and identify a and b. In this case, a = 3 and b = -6.
Therefore, by the given equation the answer will be (x-3)² - 6.

Answer:
320 grams
Step-by-step explanation:
8 bats can eat 40 grams of insects per night, and we are trying to figure out how many insects 64 bats can eat. 64 bats is 8 times as many bats as 8 bats, and we find this by dividing 64 by 8. This means they will also eat 8 times as much, so we simply have to multiply 40 by 8 to get 320 grams.
Write an equation of a line that passes through the two given points. Your answer should be written in slope-intercept form.
P(-8,-8),q ( 0,0)
Answer:
y = x
Step-by-step explanation:
Find the slope using rise over run (y2 - y1) / (x2 - x1)
Plug in the points:
(y2 - y1) / (x2 - x1)
(-8 - 0) / (-8 - 0)
-8 / -8
= 1
So, the slope is 1.
Plug in the slope and a point into y = mx + b and solve for b:
y = mx + b
-8 = 1(-8) + b
-8 = -8 + b
0 = b
Plug in the slope and y intercept into y = mx + b
y = mx + b
y = 1x + 0
y = x
So, the equation of the line is y = x

Answer:
The 4 interior angles in the square are each 90 degrees. The four angles formed by the intersection of the 2 diagonal lines are each 90 degrees. The rest of the angles <PQT, <RQT, etc. Are all 45 degrees.
Answer:
The following angles are 45 degrees: SPT, QPT, PQT, RQT, QRT, SRT, RST, PST.
The following angles are 90 degrees: STP, PTQ, QTR, RTS
Step-by-step explanation:
Notice that it is a square. Since it is a square, any diagonal line drawn from a corner to the opposite corner will bisect the angle at both corners. Since in a square each angle at each corner is 90 degrees, we know that the angles listed above are 45 degrees.
There are multiple ways to arrive at the conclusion that angles STP, PTQ, QTR, RTS are all 90 degrees. The easiest way to arrive at that answer is looking at each triangle. Notice how the square is divided into 4 triangles. Each triangle contains two 45 degree angles. Since the internal angles of each triangle must sum to 180 degrees, this means the last angle is 90 degrees.
