Using it's concept, it is found that the mean of the data-set is of [tex]\frac{3}{4}[/tex].
What is the mean?The mean of a data-set is given by the sum of all observations in the data-set divided by the number of observations.
In this problem, the 4 observations are given by:
[tex]\left{\frac{1}{2}, \frac{1}{3}, \frac{2}{3}, 1\frac{1}{2} = 1 + \frac{1}{2} = \frac{3}{2}\right}[/tex]
Hence, the mean is given as follows:
[tex]M = \frac{\frac{1}{2} + \frac{1}{3} + \frac{2}{3} + \frac{3}{2}}{4} = \frac{\frac{3 + 2 + 4 + 9}{6}}{4} = \frac{18}{24} = \frac{3}{4}[/tex]
The mean of the data-set is of [tex]\frac{3}{4}[/tex].

ABC DEF. Find the length of median CP. please help me out!
Answer:
[tex]CP = 24[/tex]
Step-by-step explanation:
The measured sides are 24 and 32 units long. It means that the larger triangle is [tex]\frac{32}{24} =\frac 43[/tex] times bigger than the smaller one. In particular, all linear measures are scaled of the same ratio: for medians we can write
[tex]FQ= \frac 43 CP \rightarrow 3FQ=4CP[/tex]
At this point we replace both segments with their lengths and solve for x. Once we find x, we can determine the length of CP.
[tex]3(2x+8)=4(3x-12)\\6x+24=12x-48 \rightarrow 6x=72 \rightarrow x=13\\CP = 3(13)-12 =36-12=24[/tex]
The length of the median CP is 24 units if the triangle ABC and triangle DEF are similar, option (C) is correct.
What is the similarity law for triangles?It is defined as the law to prove that the two triangles have the same shape, but it is not compulsory to have the same size. The ratio of the corresponding sides is in the same proportions and the corresponding angles are congruent.
The ratio of the sides:
DE/AB = 32/24 = 4/3
Similarly, the ratio of the sides:
QF/CP = 4/3
3QF = 4CP
3(2x + 8) = 4(3x - 12)
6x + 24 = 12x - 48
6x = 72
x = 12
CP = 3(12)—12 = 24 units
Thus, the length of the median CP is 24 units if the triangle ABC and triangle DEF are similar, option (C) is correct.

don't spam answer only if you know What is the measure of angle x? Enter your answer in the box
Answer:
The angle of x is 83°
Step-by-step explanation:
A straight line has a total of 180°. That means if you can figure out what the third angle on the bottom is (the one in the middle) you can add 41 to it and subtract that from 180. Since all the lines are straight you can say that the middle angle on the bottom is the same as the middle angle on the top. So:
180° - (41° + 56°) = 83°

One graphic designer takes 3 hours to design a logo. Her less experienced
colleague takes 4 hours to design a logo. How many hours would it take them to
design a total of 7 logos if they both
start working at the same time?
It takes them 12 hours to design a total of 7 logos if they both start working at the same time
RateThis is the amount per unit time.
Since one graphic designer takes 3 hours to design a logo. Her less experienced colleague takes 4 hours to design a logo, we need to find the rate at which the work is done.
The rate at which the first graphic designer works is 1 logo/3 hours = 1/3 logo/hr.Also, the rate at which the less experienced colleague works is 1 logo/4 hours = 1/4 logo/hr.So, their combined rate r = 1/3 logo/hr + 1/4 logo/hr = (4 + 3)/12 logo/hr = 7/12 logo/hr.Time to design 7 logosNow, since we require the time to desigh 7 logos, this time is T = number of logos/combined rate
= 7 logos ÷ 7/12 logo/hr
= 12 hr
So, it takes them 12 hours to design a total of 7 logos if they both start working at the same time

Let
x-----> the length of the third side AB of triangle ABC
Applying the triangle inequality theorem

One angle in an obtuse isosceles triangle measures 40°. What are the measures of the other two angles?
40° and 120°
70° and 70°
40° and 100°
80° and 80°
Answer:
40° and 100°
Step-by-step explanation:
An obtuse triangle has one obtuse angle, or an angle that measures more than 90° but less than 180°. Options 1 and 2 are not correct, because these are acute angles.
So, one of the angles must be 40°, and the other may be 100° or 120°.
The measures of the angles in a triangle add up to 180°
40° + 40° + [tex]x[/tex] = 180°
80° + [tex]x[/tex] = 180°
[tex]x[/tex] = 180° - 80°
[tex]x[/tex] = 100°
The other two angles are 40° and 100°.

How many cubes with edge lengths of 1/4 in. will it take to fill the prism?
56 cubes
375 cubes
6000 cubes
Answer:
1560
Step-by-step explanation:
First (2 1/2)/(1/4) = (5/2)(4) = 20/2 = 10
Next, 3/(1/4) = 3(4) = 12
Lastly, (3 1/4)/(1/4) = (13/4) x 4 = 52/4 = 13
This means we need 10 rows of 12, 13 high. 10(12)(13) = 1560 cubes.
Another way is to multiply 2 1/2 x 3 x 3 1/4 = 5/2 x 3 x 13/4 = 195/8
A 1/4 inch cube is 1/4 x 1/4 x 1/4 for a volume of 1/64
(195/8)/(1/64) = (195/8)(64) = 1560 cubes.

Answer:
Lori reportedly paid her mother a third of the $39. Now let's see what 1/3 of $39 is.
$13 = 39/1 x 1/3 So she paid $13, but she still owes $23 of the original $39.
So, we need to figure out what 2/3 is, and here's how: 39 - 13 = $26. She owes her mother $26.
As a result, it now indicates that she paid 1/4 of the outstanding debt. Let's see what 1/4 of $26 equals.
6.50 = 26/1 x 1/4 She repaid $6.50 of the $26 she had borrowed. And she still owes 3/4 of what she owes. Let's find out what 3/4 means now. So, remove $6.50 from $26, as follows: 26 - 6.50= $19.50.
Step-by-step explanation: See above.

8 Connor the fruiterer sells two fruit packs.
Pack 1: 10 apples and 5 mangoes ($12)
Pack 2: 15 apples and 4 mangoes ($14.15)
Determine the cost of 1 apple and 5 mangoes.
(Simultaneous equations) pleaseeee help me test tomorrow
The cost of 1 apple and 5 mangoes is $6.15.
Let's look at how to form and solve simultaneous equations in a word problem.
State assumption and define variables:Assuming that the cost of each apple and mango is equal in both packs.
Let the cost of an apple be a and that of a mango be m.
Write equations based on given information:10a +5m= 12 -----(1)
15a +4m= 14.15 -----(2)
Solve by elimination:Steps for solving equations with two variables
Ensure that the magnitude of the coefficients of one of the term is equal in both equationsEliminate the term with the chosen term through subtraction or additionSolve for the other termSubstitute the value of the term found in (3) to find the value of the second termWorking
Here, I am making the value of the coefficient of m constant.
(1) ×4:
40a +20m= 48 ----(3)
(2) ×5:
75a +20m= 70.75 -----(4)
Moving on to step 2, we can eliminate the m term by subtracting equation (3) from (4). When the sign of the terms are equal, we use subtraction to eliminate the term. On the other hand, if one of the sign is positive and the other is negative, adding the two equations together will eliminate the term (provided that you have already ensured that the magnitude of the coefficient is equal).
(4) -(3):
75a +20m -(40a +20m)= 70.75 -48
Expand:
75a +20m -40a -20m= 22.75
Simplify:
35a= 22.75
Let's continue with step 3, where we solve for a.
a= 22.75 ÷35
a= 0.65
The cost of an apple is $0.65.
Now, moving on to step 4!
Substitute a= 0.65 into (1):
10(0.65) +5m= 12
6.5 +5m= 12
5m= 12 -6.5
5m= 5.50
5 mangoes costs $5.50.
Cost of 1 apple and 5 mangoes
= $0.65 +$5.50
= $6.15
Thus, the cost of 1 apple and 5 mangoes is $6.15.

A team of researchers is monitoring the population of crickets in a particular town. They do not know exactly how many crickets are remaining, but the model they use represents the minimum number of crickets remaining in the town.
According to their model, the minimum number of the species remaining, in thousands, multiplies by 10 every month. The researchers determine that right now, the population of crickets is at least 5 thousand. Once the minimum population reaches 1 million, measures are taken to stop the increase in population.
