Answer:
Throw this sample out and start over again with a better sampling method
Step-by-step explanation:
Biased sampling leads wrong results, since the sample doesn't represent the population which is aimed to be surveyed. Higher/lower confidence level or t distribution cannot correct it.
Confidence level gives the probability of rejecting null hypothesis while it is true. And t-interval is used when the sample size is small or population standard deviation is unknown.
Before choosing confidence level or type of the statistic to infer results, one must follow random sampling not biased.
You can find the x and y intercepts by plugging 0 in for each of the variables
(0)=-7x-1
1=-7x
x=-1/7
your x- intercept is (-1/7,0)
y=-7(0)-1
y=-1
your y-intercept is (0,-1)
Answer:
The dimensions of the scaled rectangle are
of length by 
of width
Step-by-step explanation:
we know that
The scale factor is equal to 
Remember that
The scale factor is less than 1
so
the dilation is a reduction
To find the dimensions of the scaled rectangle multiply the dimensions of the original rectangle by the scale factor
The solution of the given inequality is x<-9.
<h3>What is inequality?</h3>
Inequality is the relationship between two expressions that are not equal, employing a sign such as ≠ “not equal to,” > “greater than,” or < “less than.”.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
The given inequality is |x + 10|| <1. The inequality will be solved as below:-
|x + 10|| <1
Take 10 to the right side of the inequality and solve it further.
|x || <1 - 10
x < -9
Therefore, the solution of the given inequality is x<-9.
