Answer:
She Can Buy 9 tiles before it goes over the price of the other store
Step-by-step explanation:
I multiplied 1.89 times 9 and I got the answer
This is how you would graph y=5x+1
82
*41
2*1=2
8*1=8
4*2=8
8*4=32
328+82=410
Answer:
A 90% confidence interval for the mean number of letter sounds identified in one minute is: (30.84, 37.34).
Step-by-step explanation:
We have that to find our
level, that is the subtraction of 1 by the confidence interval divided by 2. So:

Now, we have to find z in the Ztable as such z has a pvalue of
.
That is z with a pvalue of
, so Z = 1.645.
Now, find the margin of error M as such

In which
is the standard deviation of the population and n is the size of the sample.


The lower end of the interval is the sample mean subtracted by M. So it is 34.09 - 3.25 = 30.84.
The upper end of the interval is the sample mean added to M. So it is 34.09 + 3.25 = 37.34.
A 90% confidence interval for the mean number of letter sounds identified in one minute is: (30.84, 37.34).
Answer:
Sally is not right
Step-by-step explanation:
Given the two sequences which have their respective
terms as following:
Sequence A. 
Sequence B. 
As per Sally, there exists only one number which is in both the sequences.
To find:
Whether Sally is correct or not.
Solution:
For Sally to be correct, we need to put the
terms of the respective sequences as equal and let us verify that.

When we talk about
terms,
here is a whole number not a fractional number.
But as per the statement as stated by Sally
is a fractional number, only then the two sequences can have a number which is in the both sequences.
Therefore, no number can be in both the sequences A and B.
Hence, Sally is not right.
