Hello,
we must multiply the number of pages by the number of cards that hold each page to find the total number of card that she can organize, so:
5*18=90
She can organize 90 cards, but she has 95, then SHE DOESN'T HAVE ENOUGHT PAGES TO ORGANIZE THEM.
Answer:2(p+q)
Step-by-step explanation:
P=(3a-q)
Remove bracket
P=3a-q
Add q to both sides of the equation
P+q=3a-q+q
P+q=3a
Divide both sides by 3
(p+q)/3=3a/3
(p+q)/3=a
a=(p+q)/3
6a=6 x a
6 x a=6 x (p+q)/3
6a=2(p+q)
3-5X hope this is the correct way u need it to be
Answer:
20
Step-by-step explanation:
Mean is the average of the numbers. You get the average by adding all the numbers and then dividing by the amount of numbers there are.
Example: 17+24+26+13=80 divided by 4 is 20
Answer:
At 0.10 significance level, there is significant evidence that the assembly time using the new method is faster
Step-by-step explanation:
Let mu be the true mean assembly time using the new method. Then hypotheses are:
mu = 42.3 min
mu < 42.3 min
Test statistic can be found using the equation:
t= where
- X is the sample mean assembly time (40.6 min)
- M is the mean assembly time using the present method (42.3)
- s is the sample standard deviation (2.7 min)
- N is the sample size (24)
Then t= ≈ −3,08
one tailed critical t-score of 0.10 significance level with 23 degrees of freedom is ≈ 1.319
Since −3,08<--1.319, we can reject the null hypothesis.
Thus, we can conclude that the assembly time using the new method is faster
