Answer:
x=4
Step-by-step explanation:
Hey there!
I am going to use this image as an example so you can understand the formula
The formula for problems like these is
B(BA)=D(DC)
So all we have to do is plug in the numeric values
so now we have 5(5+x+3)=6(6+x)
now we just solve for x
5(5+x+3)=6(6+x)
step 1 distribute the 5 to what is in the parenthesis (5, x and 3)
5x5=25
5*x=5x
5x3=15
so now we have
25+5x+15=6(6+x)
step 2 distribute the 6 to what is in the parenthesis (6 and x)
6x6=36
6*x=6x
now we have
25+5x+15=6x=36
step 3 combine like terms, the only like terms are 25 and 15
15+25=40
now we have
40+5x=6x+36
step 4 subtract 5x from each side
5x-5x cancels out
6x-5x=x
now we have
40=x+36
step 5 subtract 36 from each side
40-36=4
36-36 cancels out
now we have
x=4 so we can conclude that x=4
hope this helps :)

answer is c
Step-by-step explanation:
I'm not going to give you the answer but I'll help you.
Step-by-step explanation:
Start by writing down your thoughts down and then form them into a paragraph.
- Write down your opinion of what classic is
- Give 3 traits/characteristics that makes that thing classic (high-quality, timeless, aged, eternal, original etc.)
- Then write down whether or not you think your definition of classic is different from the googled definition

your answer should be (-5,5) sorry if im wrong tho and if im wrong plz correct me
The probablity that the sample's mean length is greate than 6.3 inches is0.8446.
Given mean of 6.5 inches,standard deviation of 0.5 inches and sample size of 46.
We have to calculate the probability that the sample's mean length is greater than 6.3 inches is 0.8446.
Probability is the likeliness of happening an event. It lies between 0 and 1.
Probability is the number of items divided by the total number of items.
We have to use z statistic in this question because the sample size is greater than 30.
μ=6.5
σ=0.5
n=46
z=X-μ/σ
where μ is mean and
σ is standard deviation.
First we have to find the p value from 6.3 to 6.5 and then we have to add 0.5 to it to find the required probability.
z=6.3-6.5/0.5
=-0.2/0.5
=-0.4
p value from z table is 0.3446
Probability that the mean length is greater than 6.3inches is 0.3446+0.5=0.8446.
Hence the probability that the mean length is greater than 6.3 inches is 0.8446.
