Mrs. Baker selects the 10 students with the highest grade point averages to fill out a survey.

Answer:

Step-by-step explanation:

For Mr Rowley,

Ratio of Number of home works to the number of exit tickets = [tex]\frac{12}{14}[/tex]

                                                                                                      = [tex]\frac{6}{7}[/tex]

                                                                                                      = 6:7

For Ms Rivera,

Ratio of Number of home works to the number of exit tickets = [tex]\frac{36}{42}[/tex]

                                                                                                      = [tex]\frac{6}{7}[/tex]

                                                                                                      = 6:7

Since, both the ratios are same, fractions will be proportional.

[tex]\frac{12}{14}=\frac{36}{42}[/tex]

Answer:

proportional

Step-by-step explanation:

because for each game played, he pays $0.50, meaning equation is 0.50x. That is a proportional equation. The change is constant, at 0.50

please hit the heart button :)

Answer:

That would be proportional

Step-by-step explanation:

If each game is 50 cents then yes it would be proportional

If each thing is worth the same it’s proportional but if not then its not proportional

for example

1 game 50 cents

2 game 1 dollar (becuase 0.5+0.5 is 1)

3 games 1.50

ts proportional

female =male*29/71 =7282*29/71= 2974.33 =2974

Answer:

0.6395 ; 0.9657 ; 0.7333

Step-by-step explanation:

Given that:

Mean (m) = 10.1

Standard deviation (s) = 2.8

Obtain the following probabilities :

a) less than 10 minutes

P(x < 10)

Z = (x - m) / s

Z = (10 - 10.1) / 2.8

Z = 0.1 / 2.8

Z = 0.0357142

P(Z < 0.357) = 0.6395 ( Z probability calculator)

(b) longer than 5 minutes

P(x > 5)

Z = (x - m) / s

Z = (5 - 10.1) / 2.8

Z = −1.821428

P(Z < - 1.821) = 0.9657 ( Z probability calculator)

(c) between 8 and 15 minutes

P(8 < x < 15)

P(x < 8)

Z = (x - m) / s

Z = (8 - 10.1) / 2.8

Z = − 0.75

P(Z < - 0.75) = 0.22663 ( Z probability calculator)

P(x < 15)

Z = (x - m) / s

Z = (15 - 10.1) / 2.8

Z = 1.75

P(Z < 1.75) = 0.95994 ( Z probability calculator)

P(Z < 1.75) - P(Z < - 0.75)

0.95994 - 0.22663 = 0.7333

Answer:

0.25

Answer:

y = 13

Step-by-step explanation:

y = 13

Answer:

answer is 3 upon 4

Step-by-step explanation:

because if we reduce 18/24 to its lowest term so first we have to reduce 18 to and then 24 --- 18 is factor of 9x2 and 24 is factor of 12x2 then we have to cut 2 in both and there is answer 9 upon 12 still it is reducing so 3x3 is 9 and 3x4 is 12 so now we have to cut 3 in both the answer is 3 upon 4

Answer:

3w+7=31

Step-by-step explanation:

Subtract 7 on both sides

3w+7=31

     -7   -7

Divide by 3 on both sides

3w=24

/3    /3

w=8

Hopefully, this helps! :)

If 9 is 1 half of 18 that means there is a 50% chance of you picking a pencil out of the pencil case

Answer:

[tex]3)\ and\ 4)[/tex]

Step-by-step explanation:

[tex]We\ are\ given\ that,\\A\ is\ the\ set\ of\ squares.\\x\ belongs\ to\ the\ Set\ A\\y\ belongs\ to\ the\ Set\ A,\ too.\\Hence,\\Lets\ consider\ that\ \sqrt{x} =a, \sqrt{y}=b\\Hence,\\a^2=x, b^2=y\\Before\ proceeding\ we\ may\ use\ the\ following\ Laws\ Of\ Exponents:\\* For\ any\ two\ real\ numbers,\ m\ and\ n, m^a*n^a=(mn)^a\\* For\ any\ two\ real\ numbers,\ m\ and\ n, \frac{m^a}{n^a}=[\frac{m}{n}]^a\\[/tex]

[tex]Now,\\When\ we\ intend\ to\ multiply\ x\ and\ y,\\x*y=a^2*b^2\\xy=a^2*b^2\\xy=(ab)^2\\As\ the\ new\ term\ xy\ is\ the\ square\ of\ product\ of\ a\ and\ b\,\ it\\ is\ a\ square\ too.\ Hence,\ it\ belongs\ in\ the\ set\ of\ squares(A).\\Similarly,\\When\ we\ intend\ to\ divide\ x\ by\ y,\\\frac{x}{y} =\frac{a^2}{b^2}\\Hence,\\\frac{x}{y} =[\frac{a}{b}]^2\\As\ the\ new\ term\ \frac{x}{y}\ is\ the\ square\ of\ the\ quotient\ of\ a\ and\ b\ i.e\ \frac{a}{b}, the\ term\\ \frac{x}{y}\ too\ belongs\ toA[/tex]

[tex]Why\ not\ 1)\ and\ 2)?\\Because\ by\ just\ adding/subtracting\ x\ and\ y:\\x+y=a^2+b^2\\x-y=a^2-b^2\\It\ doesnt\ really\ prove\ that\ their\ sum\ say\ c\ is\ a\ perfect\ square.(except\\ in\ the\ case\ of\ Pythagorean\ Triplets [Ex. 3,4,5\ or\ 6,8,10]. Hence, As\\ not\ all\ numbers\ form\ integral\ pythagorean\ triplets,\\ (x+y)\ and\ (x-y)\ are\ not\ always\ perfect\ squares\ and\ hence,\\ dont\ belong\ to\ Set\ A.[/tex]

[tex]This\ gives\ Options\ 3)\ and\ 4)\ as\ the\ right\ answer.[/tex]
