Answer:
50
Step-by-step explanation:
you need to put first the 32 on top of 100 since it always goes over 100 then you put 16 over a blank and you divide 32 by 16 which equals 2 so since you divided at the top you need to divide at the bottom so you divide 100 by 2 and you get 50 so 50 is your answer

Answer:
a)18.8
Step-by-step explanation:
Basically, you have to add all the numbers from the data set (188) then divide them by 10 and that equals 18.8
The second part you have to add 32 to 188 ( which equals 210) and that by 11 which equals 20

In a sample of 31 kids, their mean time on the internet on the phone was 36.5 hours with a sample standard deviation of 8.3 hours. Which distribution would be most appropriate to use, when we assume these times are normally distributed
Answer:
Normal distribution
Step-by-step explanation:
Central Limit Theorem
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
In this question:
Sample of 31 kids, of a normally distributed variable. So, by the Central Limit Theorem, the most appropriated distribution to use is the normal distribution.
how do you solve the system:
y+1=2x
5y+5=10x
Answer:
choose "infinitely more solutions"
Step-by-step explanation:
Let's solve this system by substitution method
y+1=2x
- 1 = - 1
y = 2x -1 <-- sbstitute this in the next equation
---------------------------------------------------------------------------------
5y+5 = 10x
5(2x -1) + 5 = 10x
10x -5 + 5 = 10x
10x + 0= 10x
- 10x = -10x
0 = 0 <-- infinitely more solutions
Answer:
5+5=10x
y=1×5+5=10x45×+=1+32=

Find x in the follow triangle.
Answer:
Fixed
x=5.66
Step-by-step explanation:
This is an around about way since it's not a right triangle.
lets call the segment line that bisects the lower right angle= M.
The two triangles created would be similar. So:
4/6=M/(x+3)
4x+12=6M
M=(4x+12)/6
and
(x+3)/(x+4)=M/6
(6x+18)=Mx+4M
M=(6x+18)/(x+4)
since M=M
(4x+12/6=(6x+18)/(x+4)
(x+4)(4x+12)=6(6x+18)
4x^2+12x+16x+48=36x+108
4x^2+28x+48=36x+108
4x^-12x-60=0
x^2-3x-15=0
Factor
(x+2.65)(x-5.66)=0
x=5.66

you walk 1/5 miles to a music store. Then you walk another 2/3 miles to shoe store. How many miles have you walked
Answer:
1 whole mile
Step-by-step explanation:
the LCD is 15. 5x3=15. what we do to the denominator we do to the top so 1x3=3 now we have 3/15.
now do that with the other fraction
3x5=15
2x5=12
12/15+3/15= 15/15= 1 whole

Step-by-step explanation:
First find the value of Y=> 5y-8=3y+1
=> 5y-3y=1+8
=> 2y=9
=> y=4.5
Second find the value of X=> x+6=4x
=> 6=4x-x
=> 6=3x
=> x=(6/3)
=> x=2
Thus, x=2 and y=4.5 [Option C]

at school there are 8 students who only play violin, 10 students who only play guitar, 3 students who play both, and 12 students who don't play any instrument at all. if a student is randomly selected from this school, what is the probability that they play violin or guitar
Answer:
[tex]\frac{7}{11}[/tex]Step-by-step explanation:
[tex]\frac{21}{33}[/tex] simplified would be [tex]\frac{7}{11}[/tex]
The probability that they play violin or guitar is 7/11 .
What is Probability ?Probability is the likeliness of an event to occur.
It is given that
The number of students who only play violin is 8
The number of students who only play guitar is 10
The number of Students who play both is 3
The number of students who don't play either is 12
Total Students = 8+10+3+12 = 33
Total favorable outcomes (violin or guitar) = 8 + 10 +3
Probability = Total favorable outcomes / Total outcomes
Probability = 21 / 33
Probability = 7/11
Therefore the probability that they play violin or guitar is 7/11 .

Which graph is the solution to the following inequality
Step-by-step explanation:
-8x+5 > 21
Minus 5 from both sides
-8x > 16
Then divide 8 from both sides (also I am pretty sure the sign would change because you are dividing by a negative number)
x < -2
So the answer is x is less than or equal to -2

An employee at a shoe store has observed that taller customers have larger shoe sizes than customers who are shorter. She knows that shoe sizes are based on foot length, so she hypothesizes: Compared with shorter people, taller people have longer feet. Look for patterns in the data. Describe any patterns you find.
Answer:
hello some information related to your question is missing
answer : The pattern discovered supports the hypothesis that taller customers have larger shoe sizes but with some exceptions and this exceptions are ; at Height 5ft 10 inches two people are seen to have different shoe sizes i.e. Eduardo with shoe size : 10.25 inches and Susan with shoe size : 10inches. another exception from the pattern is Lily having a height of 5 ft and shoe length of 9 inches .
