I have it. Let me just type it in.
Answer with Step-by-step explanation:
Since we have given that
Some students in my class use e-mail.
It is a type of 'E' statements.
Its negation should be No students in my class use e-mail.
Because if we use "Some students in my class do not use e-mail”.
It also implies some students in my class still use e-mail.
But negation contains only opposite of given statement.
So, Some students in my class do not use e-mail” is not true.

Answer with explanation:</h2>
Given : A store owner claims that the proportion of shoppers who use coupons is less than 25%.
Then , the null hypothesis and the alternative hypothesis will be :-
, since the alternative hypothesis is left tailed , so the test is a left tailed test.
Also,t the test statistic for this hypothesis test is −1.17 and the critical value for this hypothesis test is −1.282 .
We know that when the test statistic value if greater than the critical value , then we reject the null hypothesis.
Here test statistic value(−1.17 ) is greater the critical value(−1.282) for this hypothesis , so we reject the null hypothesis.
So we conclude that there is enough evidence to support the claim.
Step-by-step explanation:
It is given that,
A 2-liter bottle of juice costs $2.80.
It means that 1 liter bottle of juice costs $1.4.
A box containing six 12-liter bottles sells for $3.90.
(6×12)l i.e. 72 liter bottles sells for $3.9
1 liter bottles sells for $0.05416
It is clear that "A box containing six 12-liter bottles sells for $3.90." have higher cost per liter. Its cost is $0.05416 per liter. Hence, the correct option is (D).
Answer:
x > 3
Step-by-step explanation:
<u>Move the Constant to the right</u>
2x > 16 - 10
<u>Subtract the numbers</u>
2x > 6
<u>Divide both sides of the inequality by 2</u>
x > 3
Hope this helps!
