Teresa stated that the heights of the students in her class were not a function of their ages. Which reasoning could justify Teresa’s statement?A.Two students are the same age but have different heights.
B.Two students have the same height but different ages.
C.No two students are the same age or height.

Answers

Answer:

Option: A is the correct answer.

A. Two students are the same age but have different heights.

Step-by-step explanation:

The height of a student could not be a function of the ages of a student because two or more students with the same age may have the different heights .

This means that a value on a x-axis (i.e. age) is mapped to two or more values i.e. corresponding y-value ( i.e. different heights) which violates the definition of function.

Hence, option: A is the correct answer.

Given f(x)=x+5 all over 3, solve for f^-1(3) (A. -1; B. 14; C. 18; D. 21)

Answers

f^-1 means finverse
find finverse then subsitute 3 for x
to solve

replace f(x) with y
solve for x
switch x with y
replace y with finverse or f^-1

f(x)=(x+5)/3
y=(x+5)/3
3y=x+5
3y-5=x
3x-5=y
finvers=3x-5

fiinverse(3)=3(3)-5
finverse(3)=9-5
finverse(3)=4
why is it not listed again

Mr. and Mrs. Romero are expecting triplets. Suppose the chance of each child being a boy is 50% and of being a girl is 50%. Find the probability of each event. P(at least one boy anf one girl)

P(two boys and one girl)

P(at least two girls)

I don't care if you cab only answer one, I would very much appreciate it if you still answered that one instead of nothing.

Answers

Answer:

1) $\text{P(at least one boy and one girl)}=(3)/(4)$

2) $\text{P(at least one boy and one girl)}=(3)/(8)$

3) $\text{P(at least two girls)}=(1)/(2)$

Step-by-step explanation:

Given : Mr. and Mrs. Romero are expecting triplets. Suppose the chance of each child being a boy is 50% and of being a girl is 50%.

To Find : The probability of each event.

1) P(at least one boy and one girl)

2) P(two boys and one girl)

3) P(at least two girls)

Solution :

Let's represent a boy with B and a girl with G

Mr. and Mrs. Romero are expecting triplets.

The possibility of having triplet is

BBB, BBG, BGB, BGG, GBB, GBG, GGB, GGG

Total outcome = 8

$\text{Probability}=\frac{\text{Favorable outcome}}{\text{Total number of outcome}}$

1) P(at least one boy and one girl)

Favorable outcome = BBG, BGB, BGG, GBB, GBG, GGB=6

$\text{P(at least one boy and one girl)}=(6)/(8)$

$\text{P(at least one boy and one girl)}=(3)/(4)$

2) P(at least one boy and one girl)

Favorable outcome = BBG, BGB, GBB=3

$\text{P(at least one boy and one girl)}=(3)/(8)$

3) P(at least two girls)

Favorable outcome = BGG, GBG, GGB, GGG=4

$\text{P(at least two girls)}=(4)/(8)$

$\text{P(at least two girls)}=(1)/(2)$

Let's represent a boy with B and a girl with G

For example BBB is three boys and BGB is two boys and one girl.

These are all the possibilities

1) BBB

2) BBG

3) BGB

4) BGG

5) GBB

6) GBG

7) GGB

8) GGG

There is in total 8 different possibilities.

Now let's analyze the conditions

p (at least one boy and one girl)

That excludes only BBB and GGG so they are 6 possibilities out of 8

p = 6/8 = 3/4

p (two boys and one girl).

Those are 3 out of 8

p = 3/8

p (at least two girls)

Those are 3 (two girls) + 1(three girls) = 4

P = 4/8 = 1/2

Please, let me know if this was satisfactory for you.

8 buttons are to 1 package as ? buttons are to 5 packages.20

Answers

8b = 1p (or p) (original statement)
To figure out how to get 5 packages, you multiply each side by 5
8b x 5 = 40b
1p (or p) x 5 = 5p
40b = 5p
So in conclusion, 40b (40 buttons) = 5p (5 packages)
Hope this helped!

40 buttons are to 5 packages

8/1 = x/5
multiply by 5 on both sides
x=40
