Answer:
$7.43
Step-by-step explanation:
f (fries) = 1.01
d (drinks) = 1.07
1.05f + 1.07d = ?
To solve this problem, you need to replace the variable with the amount of each item.
1.05(3) + 1.07(4) = ?
Now we can solve by multiplying and adding:
3.15 + 4.28 = ?
<u>7.43</u>
Answer:
There is a significant difference between the two proportions.
Step-by-step explanation:
The (1 - <em>α</em>)% confidence interval for difference between population proportions is:
Compute the sample proportions as follows:
The critical value of <em>z</em> for 90% confidence interval is:
Compute a 90% confidence interval for the difference between the proportions of women in these two fields of engineering as follows:
There will be no difference between the two proportions if the 90% confidence interval consists of 0.
But the 90% confidence interval does not consists of 0.
Thus, there is a significant difference between the two proportions.
12/16,
6/8,
3/4, and
45/60
are all equivalent to 24/32.
Now that I've listed those four, there are
only an infinite number of others remaining.
