find the mean of 11,7,2,8
mean=7
Answer:
n=4
sum =11+7+2+8=28
MEAN=sum/n=28/4=7
Answer:
The Mean is 7.
Step-by-step explanation:
Mean, or average is when you find a number that is reperesentative of the set as a whole.
To find this we add up all the values and divide it by how many values there are.
11 + 7 + 2 + 8 = 28
28/4 = 7

A baseball team has nine players whose weight, in pounds, are
174, 177, 194, 162, 196, 169, 187, 192, 178
Find the median and range of those weights
------
(I have to find the mistake in the student sample below)
174, 177, 194, 162, 196, 169, 187, 192, 178
The median is 196
196 - 162 = 34
The range is 34
HELP ME
The student forgot to sort the values first.
The sorted data set is {162, 169, 174, 177, 178, 187, 192, 194, 196}
Cross off the first four items, and cross off the last four items. You'll find that 178 is the only thing left, so it's right in the middle. This is the median.
Another way to find the median is to notice that there are n = 9 items in the list, so n/2 = 9/2 = 4.5 which rounds to 5 represents the slot number where the median is located. The value 178 is in slot 5. This trick only works if n is odd.
The range is the difference between the min and max, so,
range = max - min = 196-162 = 34
The student got the range part correct.
---------------------
Summary:
Median = 178
Range = 34

A 3-member committee has to be formed from 2 teachers and 2 parents. How many combinations are possible?
Step-by-step explanation:
the answer is in the above image
The number of combinations possible if a 3-member committee has to be formed from 2 teachers and 2 parents is 4 combinations
Combination and permutationCombinations have to do with selection compared to permutation that has to do with the arrangement.
If a 3-member committee has to be formed from 2 teachers and 2 parents, the total committee is given as:
Total committee members = 2 + 2
Total committee members = 4 committees
If 3-member committee has to be formed from them, the number of ways this can be done is given as:
4C3 = 4!/(4-3)!3!
4C3 = 41/3!
4C3 = 4 ways
Hence the number of combinations possible if a 3-member committee has to be formed from 2 teachers and 2 parents is 4 combinations

the furniture store sells dining room tables and chairs. single chairs for particular table sell for 75.00 each. the cost for four chairs when the customer purchases the entire set is 200. what is the percent savings on the 4-chair set rounded to the nearest whole percent?
a.25%
b.33%
c.50%
d.66%
Answer:
B, 33%
Step-by-step explanation:
Let us find the original price of four chairs without the special deal, and compare it with the deal to find the percent savings.
Step 1:
A customer must buy 4 chairs costing $75 each to recieve the deal. Let us multiply 4 by 75 to find the total cost without the deal:
[tex]4*75=\\300[/tex]
Step 2:
We now know the original cost of the 4 chairs, and the price of 4 chairs with a deal. Let us subtract the difference of costs and convert it into a percentage to find percent savings:
[tex]300-200=100\\\frac{100}{300} =\frac{1}{3}[/tex]
[tex]\frac{1}{3}=33[/tex]%
Therefore, B, the percent savings is 33%.

Experts believe the rate of obesity (defined as having a BMI greater than 30) of adults in the United States is approximately 24.5%. A Gallup poll examined the rate of obesity in adults in the United States with a survey of 86,664 randomly sampled U.S. adults. Of the adults surveyed, 23,053 said that they were obese. Select the best description of the sample.
Answer:
86,664 randomly selected U. S Adults
Step-by-step explanation:
The sample is a subset of the population, that is a representative observation which is chosen from a larger population usually used in place of the population due to various reasons which may hamper the use of the entire population on a certain research project. Here, the population of interest is the entire U.S adult.
The subset of the population employed is the 86,664 randomly sampled US adults, this is called the sample as it representative of the population of interest.

If g(x) = √x and h(x) = x^3 - 1, what is g(h(4))
Answer:
Here, given
g(x) = √x
h(x) = x³-1
For gh(4) , we have to find gh(x), so,
gh(x) = g(x³-1)
=√x³-1 [Note⇒root is both for x³ and 1]
Now,
gh(4) = √4³-1

What is the angle measure of the third angle of a triangle given the two angles below? 59 degrees and 58 degrees
Answer:
firstly a triangle has angle sum of 180°
Step-by-step explanation:
let all the three angles be x,y and z such that x+y+z =180°
let x= 58° and y =59°
the to calculate for the unknown z angle ;
make z subject of the formula
thus z= 180° -x-y
> z= (180-58-59)°
z= 180-117
z= 63°
Answer:
63
Step-by-step explanation:
59 + 58 = 117
180 - 117 = 63
To find a third angle you will subtract the sum of the two given angles from 180 because all you have to know is that all of the angles in a triangle always add up to 180°.

Answer:
D. x ≈ 3.3, y = 15.7
Step-by-step explanation:
x = Opposite
y = Adjacent
16 = Hypotenuse
θ = 12°
To find x, we solve using the Trigonometric function of Sine
sin θ = Opposite/ Hypotenuse
x = Opposite
sin 12 = x/16
Cross Multiply
x = sin 12 × 16
x = 3.3265870531
Approximately, x ≈ 3.3
To find y, we solve using the Trigonometric function of cosine
cos θ = Adjacent/ Hypotenuse
y = Adjacent
cos 12 = y/16
Cross Multiply
y = cos 12 × 16
y = 15.650361612
Approximately, y ≈ 15.7
Therefore, x ≈ 3.3, y = 15.7

If H is the center of the circle, find mGJI A 117.33 B 222.57 C 242.67 D 256.56
40 POINTS! PLEASE HELP
Answer:
GJI = 242.67
Step-by-step explanation:
A circle is 360 degrees
GI + GJI = 360
The arc length is the same as the angle when it is at the center
117.33 + GJI = 360
GJI = 360 - 117.33
GJI = 242.67
Answer:
GJI = 242.67
Step-by-step explanation:
GI + GJI = 360
117.33 + GJI = 360
GJI = 360 - 117.33
GJI = 242.67

Un deposito de agua tiene forma de prisma rectangular con los lados de la base de 25 y 20 metros. Calcula la altura que pueda contener 1000 metros cúbicos de agua
Answer:
La altura del depósito para que pueda contener 1000 metros cúbicos de agua es 2 m.
Step-by-step explanation:
Para calcular el volumen de un prisma rectangular, es necesario multiplicar sus 3 dimensiones: longitud*ancho*altura. El volumen se expresa en unidades cúbicas.
En este caso, se conoce la longitud y el ancho, cuyos valores son 25 y 20 metros. A su vez, se sabe que el depósito de agua debe contener 1000 m³. Entonces, siendo:
Volumen= longitud*ancho*altura
Y reemplazando los valores se obtiene:
1000 m³= 25 m* 20 m* altura
Resolviendo:
1000 m³= 500 m²* altura
[tex]altura=\frac{1000 m^{3} }{500 m^{2} }[/tex]
altura= 2 m
La altura del depósito para que pueda contener 1000 metros cúbicos de agua es 2 m.
Samantha is creating concrete spheres for a weight-lifting competition. One of the spheres needs to have a weight of 350 pounds. Samantha knows that concrete weighs 150 pounds per cubic foot, in feet, of the sphere that Samantha will create?
The volume occupied by a 350 pound sphere is 2.33 ft³.
EquationEquation is an expression used to show the relationship between one or more numbers and variables.
Let y represent the weight of the sphere in pounds and x represent the volume in feet³, hence:
y = 150x
For a 350 pounds sphere:
350 = 150x
x = 2.33 ft³
The volume occupied by a 350 pound sphere is 2.33 ft³.

Both angles are congruent because they are opposite exterior angles.
6x+2=x+17
5x=15
x=3
Answer:
x = 23 °
Step-by-step explanation:
6 x + 2 ° + x + 17 ° = 180 °
combine like terms
6x + x + 2 ° + 17 ° = 180 °
7 x + 19 ° = 180 °
7 x = 180 ° - 19 °
7 x = 161 °
x = 161 ° / 7
x = 23 °

Step-by-step explanation:
To find who saves the greatest. Find who spent the least.
That is find the smallest of these fractions.
To find the smallest among the fraction:
Step 1 : make the denominators the same.
Step 2 : to make denominators same find LCM of 8, 4, 3, 6
Step 3: LCM = 24
