Find the mean of the data set {4.5,5, 3.5, 2, 2.5}.
So what is the answer ;, I nordeste im
Answer:
Mean = 3.5
Step-by-step explanation:
The given data is :
4.5,5, 3.5, 2, 2.5
We need to find the mean of the given data.
We know that,
Mean = sum of observations/total no. of observations
Here,
Total no. of observations = 5
Sum of observations = 4.5 + 5+ 3.5+ 2+ 2.5 = 17.5
Mean,
[tex]m=\dfrac{17.5}{5}\\\\m=3.5[/tex]
Hence, the mean of the data set is equal to 3.5.
Find the value of x
a) 57
b) 60
c) 69
d) 63
Answer:
b
Step-by-step explanation:
The tangent- secant angle 55° is equal to half the difference of its intercepted arcs, that is
[tex]\frac{1}{2}[/tex] (170 - x) = 55 ( multiply both sides by 2 to clear the fraction )
170 - x = 110 ( subtract 170 from both sides )
- x = - 60 ( multiply both sides by - 1 )
x = 60 → b
The measurement of angle C is _____ degrees
Answer:
23°
Step-by-step explanation:
157° = D
D + C = 180°
157 + C = 180
(group like terms)
C = 180 - 157
C= 23°

Step-by-step explanation:
on a highway, Nick's car uses 12.5 gallons of gas to travel 240 miles. The gas tank in Nick's car holds 20 gallons of gas.
How far can Nick's car travel on a highway using a full tank of gas?
Answer:
Nick's can travel 384 miles on a highway using a full tank of gas of his car
Step-by-step explanation:
Given
Fuel used by Nick's car = 12.5 gallon
In 12.5 gallon Nick can travel up to 240 miles
The gas tank of Nick's car can hold upto 20 gallons of fuel
With a full tank Nick can travel
[tex]\frac{240}{12.5} * 20 \\384[/tex]miles
Tell whether the function table represents a linear or exponential relationship.
Answer: Linear
Step-by-step explanation: When determining whether the function table represents a linear or exponential relationship, we are checking to see if the rate of change is constant or increasing. If we look at the table, when x increases by 1, y increases by 3. This means that on that interval, the average rate of change is 3/1 = 3. When we increase x by 1 again, we see that y increases by 3 again. This means that the rate of change is constant for the function, so it must be linear.

please help with this. I only need help with the first question I have the second one figured out,
Answer:
m∠WZX = 41°
Step-by-step explanation:
diagonals bisect angles and opposite angles are congruent
therefore, ∠WXY ≅ ∠WZY
∠WZY must equal [360 - 2(68)] ÷ 2 which equals 112°
If ∠WXZ = 71° then so does ∠XZY
Which means that ∠WZX must equal 112-71 which is 41°
===================================================
Explanation:
Refer to the diagram below. I've marked up the figure with various angles to point out the angles we'll be working with.
angle XYZ = 68 in greenangle WXZ = 71 in redangle WZX = unknown, in blueTo make things a bit simpler in terms of notation, and to match up colors with variable letters, I'm going to use the following
R = red angleG = green angleB = blue angleNotice how the two red angles I've marked up are alternate interior angles. This works because WX is parallel to ZY. Also notice that the red and blue angles combine to form the angle WZY, which is adjacent to angle XYZ in green.
For any parallelogram, the adjacent angles always add to 180.
(angle WZY) + (angle XYZ) = 180
(blueAngle+redAngle) + (greenAngle) = 180
(B+R) + (G) = 180
(B+71) + (68) = 180
B+139 = 180
B = 180-139
B = 41
The blue angle is 41 degrees, which means angle WZX is 41 degrees

Answer:
Step-by-step explanation:
What is the probability that a customer ordered
a hot drink given that he or she ordered a large?
So we are looking for the percentage of a hot drink and a Large.
Our list:
Small
Medium Large
Hot
5
48
22
8
12
5
Cold
He can tell there is 10% atleast for hot and 0% for a large
The probability that a customer ordered a hot drink given that he or she ordered a large is 22%
What is probability?Probability denotes the possibility of the outcome of any random event.
Given that a table of the first 100 customers' orders at a coffee shop.
We need to find the probability that a customer ordered a hot drink given that he or she ordered a large,
= 22 / 100
= 22%
Hence, the probability that a customer ordered a hot drink given that he or she ordered a large is 22%

A classroom has a length of 20ft. And a width of 30ft. The flooring is to be replaced by tiles. If each tile has a length of 24 in and a width of 36 in, how many tiles are needed to cover the classroom?
Answer:
100
Step-by-step explanation:
first we need to turn the feet into inches
20x12=240
30x12=360
now to get the area of the floor we need to do 360x240=
86,400
now the area of each tile is 24x36=864
now to find out how many tiles fit on the floor we need to do 86,400 divided by 864 which = 100

Aldo needs 46 cookies for a party.
The cookies he wants come in packs of 8.
How many packs should he buy?
Answer:
6 Packs
Step-by-step explanation:
Since he needs 46 cookies, he will have to buy 46/8 which is 5.75 packs. But since the packs are sold in whole, not fractions, he buys a ceil approximation of the packs which is 6, because if he buys 5, it will not be enough.

A school has 100 students doing extra lessons 36 students were enrolled in mathematics and English, 4 students were enrolled in both subjects. How many students in an extra lesson that does not do either subject. Explain how you got your answer.
Answer:
60
Step-by-step explanation:
If a school has 100 students doing extra lessons, then;
n(U) = 100
If 36 students were enrolled in mathematics and English. then;
n(MuE) = 36
If 4 students were enrolled in both subjects, then;
n(MnE) = 4
Let n(MuE)' be those that does not do either subject
hence;
n(U ) = n(MuE) + n(MuE)'
100 = 36 + n(MuE)'
n(MuE)' = 100 - 36
n(MuE)' = 64
Since 4 students were enrolled in both, hence (64-4) i.e 60 does not do either subject.

C.P. = Rs400, Loss = 12% , Find S.P
Answer:
Step-by-step explanation:
CP= Rs 400
loss%=12%
let sp be x
SP=CP-loss%*CP
x=400-12/100*400
x=40000-4800/100
x=35200/100
x=352
therefore sp =Rs 352
Answer:
S.P. = ₹352
Step-by-step explanation:
UNITARY METHOD:
If C.P. = ₹100
Then SP = ₹(100-12) = ₹88
If C.P. = ₹1
S.P. = ₹(88/100)
Then, as given: C.P. = Rs 400
S.P. = ₹( 88/100)*400
= ₹352
Therefore, S.P. = ₹352

A biologist studying the relationship between tilapia and catfish in a pond finds that the ratio of tilapia to catfish is 6:20. If the pond has 30 catfish, how many tilapia are in the pond?
Answer: 9 tilapia
Step-by-step explanation:
The ratio of 6:20 for tilapia to catfish means that for every six tilapia, there are 20 catfish in the pond.
If there are 30 catfish, use direct proportion to find out the number of tilapia:
6 : 20
x : 30
Cross multiply:
20x = 180
x = 180 / 20
x = 9 tilapia
