Answer:
MEAN
Step-by-step explanation:
Out of the measures of dispersion, the measure that best describe a set of data is the mean because it calculates the average of the data. Also, it helps to detect if there are outlier or not.
Given the sets of data;
2, 1, 3, 0, 4, 4, 1, 2, 0, 6, 2, 2, 5, 0, 2, 3, 3, 1, 1, 4, 2, 0, 1, 4
Mean = sum of data/sample size
Sum of data = 2+1+3+0+4+4+1+2+0+6+2+2+5+0+2+3+3+1+1+4+2+0+1+4
Sum of data = 53
Sample size = 23
Mean = 53/23
Mean = 2.3
F is inversely proportional to d^2.
When F = 5, d = 9
Work out d (positive value rounded to 2 DP) when F = 3
Answer:
11.6
Step-by-step explanation:
F = k/ d^2
where k = proportionality constant
k = Fd^2
k = 5 * 9^2
k = 5*81 = 405
d = (K/F)^1/2
d = (405/3)^1/2
d = 11.62 =11.6
Answer:
11.62
Step-by-step explanation:
F is inversely proportional to d^2, so
[tex]F=\frac{k}{d^2}[/tex]
for some constant k. To find k plug in given values for F and d.
[tex]5=\frac{k}{9^2}\\5=\frac{k}{81}\\k=405[/tex]
Now you can find d for F = 3.
[tex]3=\frac{405}{d^2}\\\\3d^2=405\\\\d^2=135\\d=\sqrt{135}\approx 11.62[/tex]
What is the y intercept for the equation –2x + 5 = –10?
a.) (0, 5)
b.) (0, –2)
c.) (0, 2)
d.) (0, –5)
Rewrite the equation of the line in slope intercept form.
4x−8y=32
Answer:
y=1/2x-4
Step-by-step explanation:
subtract 4x from the left side and the right side. It becomes:
-8y=-4x+32
divide -8 from both sides and it becomes:
y=1/2x-4

What is the domain of the function Y = tan(x/8)?
Oall real numbers except 4pi+4npi where n is any integer
Oall real numbers except 4pi+8npi where n any integer
Oall real numbers except 8pi+4npi, where n is any integer
Oall real numbers except 8pi+8npi, where n is any integer
Answer:
B) all real numbers expect 4pi+8pi where n is any integer
Step-by-step explanation:
The domain of the function y = tan(x/8) is given by: All real numbers except 4π+8nπ , where n is any integer.
What is the domain of a function?The domain is the set that contains all possible input values for the function.
Since we know that Tangent of an angle is sine of the angle divided by the cosine of the angle, and the cosine is 0 at:
π/2 + nπ
Hence, let a composite tangent function , the domain is given by:
f(x) does not equal to π/2 + nπ
we have that , hence the domain is:
all real numbers except 4π+8nπ
All real numbers except 4π+8nπ, where n is any integer.

The formula for the volume of a cone is V=\frac{1}{3}\pi r^2 h,V=
3
1
πr
2
h, where rr is the radius of the cone and hh is the height of the cone. Rewrite the formula to solve for hh in terms of rr and V.V.
Answer:
3V/ (pi r^2) = h
Step-by-step explanation:
V = 1/3 pi r^2 h
Solve for h
Multiply each side by 3
3V = 3 * 1/3 pi r^2 h
3V = pi r^2 h
Divide each side by pi r^2
3V/ (pi r^2) = pi r^2 h/ ( pi r^2)
3V/ (pi r^2) = h

Kevin Hill deposited 15,483 pennies. He put 50 pennies in each penny roll. How many full rolls did he have?
Answer:
309 full rolls
Step-by-step explanation:
Find how many full rolls he had by dividing 15,483 by 50:
15,483/50
= 309.66
Since the question asks for full rolls, the answer has to be a full number.
So, the answer is 309 full rolls

3. In a class of 50, the # of people with brown hair is 2 more than 5 times the number of people with red hair. How many
brown/red-haired people are there in the class? (Everyone in the class has either brown or red hair)
Answer:
8 red haired and 42 brown haired
Step-by-step explanation:
I chose a random number to start off with (which is 8) and I multiplied it by 5.
8•5=40 and then you have to add 2, so you get 42.
42+8 = 50
The equation would be (5x+2)+x where 'x' is the number of people with red hair.
can somone help plz i need help
Answer:
about 7.3 units
Step-by-step explanation:
to find the answer you do Pythagorean theorem
so you have (-9, -4) and (-2, -6)
you do X1-X2 and Y1-Y2
so -4-(6)=2
and -9-(-2)= -7
now you do a^2 + b^2 = C^2
so 2^2 + -7^2 = C^2
which is 4 + 49= C^2
53=C^2
√53=7.3
so 7.3 units :)
Blake has 864 square inches of material with which to create a hollow three-dimensional container. He decides to make either a cube or a sphere.
Which solid would have the greater volume? What is the greatest volume he can achieve with this amount of material?
Answer:
I think it's a cube, because the cube has bigger spaces because of the edges, but I don't know how much...

Answer:
n = - [tex]\frac{4}{7}[/tex]
Step-by-step explanation:
Given
[tex]\frac{2}{3}[/tex] (1 + n) = - [tex]\frac{1}{2}[/tex] n
Multiply both sides by 6 ( the LCM of 3 and 2 ) to clear the fractions
4(1 + n) = - 3n ← distribute left side
4 + 4n = - 3n ( add 3n to both sides )
4 + 7n = 0 ( subtract 4 from both sides )
7n = - 4 ( divide both sides by 7 )
n = - [tex]\frac{4}{7}[/tex]

Two forces, one of 45 pounds and the other 50 pounds, act on the same object. The angle between the forces is 33°. Find the magnitude of the resultant vector. Pls help :( cant afford to fail
Answer:
The magnitude of the resultant force is: 27.40 pounds
Step-by-step explanation:
Given
[tex]F_1 = 45[/tex]
[tex]F_2 = 50[/tex]
[tex]\theta = 33[/tex]
Required
The magnitude of the resultant vector
To do this, we apply cosine formula
[tex]R^2 = F_1^2 + F_2^2 - 2 * F_1 * F_2 * \cos(\theta)[/tex]
This gives:
[tex]R^2 = 45^2 + 50^2 - 2 * 45 * 50 * \cos(33)[/tex]
[tex]R^2 = 2025+ 2500 - 4500* 0.8387[/tex]
[tex]R^2 = 2025+ 2500 - 3774.15[/tex]
[tex]R^2 = 750.85[/tex]
Take square roots of both sides
[tex]R = \sqrt{750.85\\[/tex]
[tex]R = 27.40[/tex]

Answer:
(a) 0.6
(b) 0.4
Step-by-step explanation:
If I am reading the little table right, You have made 9 shots, and have missed 6 of them. Therefore, in total, you have made [tex]9+6=15[/tex] shots.
The definition of probability is the number of events of a desired outcome divided by the total number of outcomes. Since you wish to make a shot for part a, the number of desired outcomes thus far is 9, out of 15 total shots. Thus,
[tex]P([/tex]making a shot[tex])=\frac{9}{15}=\frac{3}{5}=0.6[/tex]
Since making a shot and not making a shot are mutually exclusive events, and the only two events that could occur when shooting a basket, the probability of not making a shot and the probability of making a shot are all of the possible outcomes, and is thus equal to 1.
[tex]P([/tex]making a shot[tex])+P([/tex]missing a shot) [tex]=1[/tex]
[tex]P([/tex]missing a shot[tex])=1-P([/tex]making a shot[tex])[/tex]
[tex]P([/tex]missing a shot[tex])=1-0.6=0.4[/tex]

Mark estimated that he would spend $300 of his paycheck on seven items that cost $50 each. Why is this not reasonable?
A. It is not reasonable because seven items could not all cost $50.
B. It is not reasonable because seven items at $50 each, would cost a total of $350.
C. It is not reasonable because seven items at $50 each would only cost $420.
D. It is not reasonable because he would have too much money left over.
