Answers

Answer 1

Answer:

Answer:

a total of 8 outfits

Step-by-step explanation:

shoes: L1, L2

shirts: S1, S2

pants: P1, P2

1: S1, P1, L1

2: S1, P1, L2

3: S1, P2, L1

4: S1, P2, L2

5: S2, P1, L1

6: S2, P1, L2

7: S2, P2, L1

8: S2, P2, L2

I hope that makes sense, since I couldnt figure out how to show the diagram.

HELP PLEASE I WILL GIVE BEST ANSWERAngela is studying two types of birds. She measures the wingspan, in inches, of five Type 1 birds and five Type 2 birds.

What can she infer about the wingspans of the two types of birds?

Type 1: {18, 24, 20, 22, 26}
Type 2: {24, 21, 19, 26, 30}

A.
Type 1 and Type 2 birds have similar wingspan distributions.

B.
Type 1 and Type 2 birds have somewhat similar wingspan distributions.

C.
Type 1 birds and Type 2 birds do not have similar wingspan distributions.

D.
Type 1 birds and Type 2 birds have identical wingspan distributions.

Answers

Answer:

Step-by-step explanation:

The given data set for type 1 of birds is:

Type 1: {18, 24, 20, 22, 26}

Type 2: {24, 21, 19, 26, 30}

Mean of the type 1 data is:

$Mean=(18+24+20+22+26)/(5)=(110)/(5)=22$

Data $(x-{\overline{x})^2$

18 16

24 4

20 4

22 0

26 16

Now, mean average of squares is:

$m=(40)/(5)=8$

Standard deviation= $SD=√(8)=2.828$

Now, the difference of mean and its standard deviation of type 1 data set is:

=22-2.828

Difference =19.172

The given data set for type 2 of birds is:

Type 2: {24, 21, 19, 26, 30}

Mean of the type 2 data is:

$Mean=(24+21+19+26+30)/(5)=(120)/(5)=24$

Data $(x-{\overline{x})^2$

24 0

21 9

19 25

26 4

30 36

Now, mean average of squares is:

$m=(74)/(5)$

$m=14.8$

Standard deviation= $SD=√(14.8)=3.84$

Now, the difference of mean and its standard deviation of type 2 data set is:

=24-3.84

Difference=20.16

Since, the difference of mean and standard deviation of both type 1 and type 2 data set is different, therefore, Type 1 birds and Type 2 birds do not have similar wingspan distributions.

Hence, option C is correct.

Answer:

Type 1 and Type 2 birds have similar wingspan distributions.

List 2/3 , 7/12 , and 3/4 from greatest to least thanks .

Answers

for this question you should know that:
2/3 = 8/12
and
3/4 = 9/12
so now you can say:
7/12 < 8/12 < 9/12
so:
7/12 < 2/3 < 3/4 :)))
i hope this is helpful
have a nice day

Forget the numerators, focus on the denominators for now. 3 an 4 are both multiples of 12, so we can multiply $(2)/(3)$ by 4 and $(3)/(4)$ by 3 to make all the fractions out of 12. This should make it easier to understand which one is the smallest / biggest.

$(2)/(3)$ × 4 = $(8)/(12)$

$(3)/(4)$ × 3 = $(9)/(12)$

You leave $(7)/(12)$ as it is because it's already out of 12.

Now you can see that obviously, $(3)/(4)$ is the largest fraction, as 9 is the biggest when it's out of 12. $(2)/(3)$ is the second largest as it's 8 out of 12, which is smaller than 9 but bigger than 7. Obviously, the last is one is $(7)/(12)$ .

So the order is:

$(3)/(4)$ , $(2)/(3)$ , $(7)/(12)$ .

The answer show work please
