The average electric guitars sold each year in Wyoming is 13,057.
Multiplication of two numbers is defined as the addition of one of the number repeatedly until the times of the other number.
a × b means that a is added to itself b times or b is added to itself a times.
Given that,
on average the number of electric guitars sold in Texas each year is $91,399, which is seven times the average number of guitars sold each year in Wyoming.
Average number of guitars sold each year in Texas = 91,399
This number is seven times the average number of guitars sold each year in Wyoming.
Let x be the average number of guitars sold in Wyoming each year.
7x = 91,399
Dividing both sides of the equation by 7,
x = 91399 / 7
x = 13,057
Hence 13,057 electric guitars are sold each year in Wyoming.

Yes, because the source of the data was unbiased.
Yes, because the results are unlikely to occur by chance.
No, because the sample size was too small to reach a conclusion.
Answer:
Step-by-step explanation:
Here population parameter p= 1% = 0.01
But sample proportion = 0.03
Sample size = n=600
Std error of the sample =
Let us assume significance level as 5%
For proportion z critical for 95% is 1.96
Margin of error = 1.96(std error) = 0.024
Conf interval for proportion lower bound = 0.01-0.024 =- 0.014
Upper bound = 0.01+0.024 = 0.124
Thus conf interval (-0.014, 0.124)
Our sample proportion is 0.03 which does not lie within this interval.
Hence we conclude that
Yes, because the results are unlikely to occur by chance.
Answer:
Yes, because the results are unlikely to occur by chance.
Step-by-step explanation:
We have to remember that when dealing with statistics the larger the sample we are taking, the more the results will tend to the statistical reality, for example, if we flip a coin, the chances or statistics are 50%-50% but if we only toss it two times, theres a singnificant chance that it could be 100% tails, the more we continue to toss the coin, the closer we will get to the 50-50, here we have a really large sample of 600 computers, where 3% of them were defective, so we can assure that it wasn´t by chance, because an increase of 2% on the percetange of the defective devices from the ideal to the reality is not by chance.
A) m = undefined and point (-2,5)
B) m = 0 and point (-2,4)
C) m = undefined and point (5,-2)
D) = zero and point (5,0)
Answer: Choice A
m = undefined
point (-2,5)
==================================================
Explanation:
The equation x = -2 describes a vertical line in which every point on this line has x coordinate -2. Two points on this line are (-2,0) and (-2,1)
Another point on this line is (-2,5) since this also has x coordinate -2.
------------------
All vertical lines have undefined slope.
Let's pick two points such as (-2,0) and (-2,1) and find the slope through them
m = (y2-y1)/(x2-x1)
m = (1-0)/(-2-(-2))
m = (1-0)/(-2+2)
m = 1/0
m = undefined, since we cannot divide by zero.

A. 1/14
B. 1/27
C. 13/14
D. 13/27
E. 14/27
The probability that the person chosen is a boy is 14/27.
Number of girls = 13
Number of boys = 14
Total students = 27
Probability is a measure of the likelihood of occurrence of an event.
P(event) = Favorable outcomes / total outcomes
Favourable outcomes = 14 because there are 14 boys
Total outcomes =27
So, the probability that the person chosen is a boy will be given by:
P(boy)=14/27
So, the probability that the person chosen is a boy is 14/27.
Hence, the probability that the person chosen is a boy is 14/27.

Answer:
E
Step-by-step explanation:
It's E because you have to add 13 and 14 and as you can see there's 14 boys so it's E.
