Answer:
c. Yes because the cut-off is more than the sample mean
Step-by-step explanation:
The null and alternate hypotheses are
H0 : u= 3.5 ounces vs Ha: u > 3.5 ounces
The mean and standard deviation of the sample are calculated to be 3.76 and 0.24
The test statistics is
t= x`- u/s√n
= 3.76-3.5/0.24/√10
= 0.26/0.07589
=3.426
The critical region for z test is z > ± 2.33
The critical region for t test is t > ± 2.82 for 9 d.f
For both the tests( z and t) the test statistic =3.426 lies in the critical region.
Hence we reject H0 and accept the hypothesis that the new design is better than the old one at a level of significance of 1%.
cut-off = mean + 3 times the standard deviation
= 3.76 + 3* 0.24
cut-off =4.48
Yes, the cut off is more than the sample mean.
So choice c is the best option.

Answer:
C. C,D,A,B,E
Step-by-step explanation:
The first set of coordinates, (-3, 4) and (3, 4) are on the horizontal line y=4. The distance between them is the difference of their x-values: 3 -(-3) = 6. This is the third distance on the list, so 'A' will be 3rd in the sequence of matching.
Choices A and C have 'A' listed 3rd.
__
The second set of coordinates (-5, 3) and (-5, 11) are on the vertical line x=-5. The distance between them is the difference of their y-values: 11 -3 = 8. This is the 4th distance on the list, so 'B' will be 4th in the sequence of matching.
Choice C has 'B' listed 4th.
The appropriate sequence of matching is ...
C, D, A, B, E

Additional comment
In this problem, as in most multiple-choice problems, it isn't necessary to find the complete answer. It is only necessary to find enough of the answer to determine the correct choice among those offered. You do need to know enough about how to work the problem to be able to tell a correct choice from an incorrect one. Knowing the required relationships is useful; slogging through the arithmetic is often not necessary.

Which images are tessellations?
Image 1 and 4
Image 3 and 2
Image 1 only
Image 3 and 4
Option - D - Image 3and 4 is correct
We have the following images.
We have to classify which image is a tessellations.
What are tessellations?tessellations is also called tiling which involves the covering up of rigid plane surface using the geometric shapes (tiles) ensuring that these shapes don't overlap and leave no gap.
In the image 3, we have a geometric shape called triangle which is used as a tile to cover the surface. These shapes don't overlap and leave no gap as they perfectly fit with one another. Similar is the case with image 4, where hexagonal tiles are used. Therefore, image 3 and 4 are tessellations. The images 1 and 2 does not have any predefined geometric shape and nothing can be said about their perfect fit. Hence these are not tessellations.
Hence, Option - D is correct.

Select the graph of y= sin x.
Because it contains the points (0, 0) and (pi/2, 1), the first graph is the graph of sin(x).
Which graph is the graph of sin(x)?To identify the graph of sin(x), we need to remember some points of the sine function.
We know that sin(0) = 0, this means that this passes through the point (0, 0).
And we also know that sin(pi/2) = 1, then it also passes through the point (pi/2, 1).
With that in mind, the graph that passes through those two points is the first one, so that is the correct option.

Step-by-step explanation:
So, the small red circles are the baskets.
Each 1 represents 1 basket.
We know that the two baskets on 4 wont be counted, as well as the two baskets on 4 1/2, since thats smaller than or equal to 4 1/2
We also know that the two baskets on 6 wont be counted either, since thats equal to 6.
So now lets count the baskets in between these values, which would be:
5 - 4 baskets
5 1/2 - 4 baskets
Lets add those up:

Dr. Gavin is conducting a 2 x 4 independent-groups factorial design. Assuming he wants 25 people in each cell, how many participants does Dr. Gavin need to recruit
Answer:
Dr. Gavin needs to recruit 200 participants.
Step-by-step explanation:
Dr. Gavin is conducting a 2 x 4 independent-groups factorial design.
This means that there will be 2*4 = 8 cells.
Assuming he wants 25 people in each cell, how many participants does Dr. Gavin need to recruit?
25 people in each cell, 8 cells. So
25*8 = 200
Dr. Gavin needs to recruit 200 participants.

Make r the subject of x= e + r/d
Step-by-step explanation:
X=e+r/d
swap both sides
e+r/d=x
subtract e from both sides
e-e+r/d=x-e
r/d=x-e
multiply d to both sides
d×r/d=x-e×d
r=x-e×d

1.5 m
2500 mm
850
4.8m
whats the total length
Answer:
Step-by-step explanation:
1.5m
(2500mm)/(1000 mm/m) = 2.5m
(850mm)/(1000 mm/m) = 0.85m
4.8m
Add the number of meters:
1.5 + 2.5 + 0.85 + 4.8 = 9.65m
We have the given measurements 1.5 m, 2500 mm, 850, 4.8m. Therefore, the total length would be 9.65m.
How to convert a millimeter into a meter?One meter is equal to 1000 millimeters. So, to convert one millimeter into a meter we have to divide by 1000.
We have the given measurements 1.5 m, 2500 mm, 850, 4.8m
To convert a millimeter into a meter
2500 mm
= (2500mm)/(1000 mm/m)
= 2.5m
850mm
(850mm)/(1000 mm/m)
= 0.85m
Add the number of meters:
= 1.5 + 2.5 + 0.85 + 4.8
= 9.65m
Therefore, the total length would be 9.65m.
