The shortest adult skeleton at Mütter stands 3 1/2 feet. The tallest skeleton in the museum stands 2 1/7 times taller. How tall
Romashka [77]
You add 3 1/2 to 2 1/7 to get the tallest skeleton.

3 1/2 = 7/2 and 2 1/7= 15/7

First you find common denominators for both fractions. 2 and 7 go into 14.

2 times 7 equals 14
7/2 * 7 = 49/14

7 times 2 equals 14
15/7 * 2 = 30/14

49/14 + 30/14= 79/14

then you simplify 79/14.... 14*5= 70 and 9 are left over. 5 9/14

Matt can walk 500 m from his home on King Street, and then 900m along Queen Street to go to his school. He can also walk across
brilliants [131]

Answer:

He walks 1030 meters if he walks across the park.

Step-by-step explanation:

In order to solve this question we will need to know that c^{2} = a^{2} + b^{2} (were c is the length of the hypotenuse (the diagonal line) of a right angle triangle, and a and b are the legs (the sides that form a right angle). So them means that.....

Let "c" be the distance he will need to walk if he was going to go through the park

Let "a" be the distance he walks on King Street

Let "b " be the distance he walks on Queen Street, then.....

c^{2} = a^{2} + b^{2}

c = \sqrt{a^{2} + b^{2} }

(Now plug in the values of a and b and get.....)

c = \sqrt{500^{2} + 900^{2}  }

c = \sqrt{1060000 }

c = 1029.563014............

So I would assume that you have to round to the nearest meter. And as a result we get 1030 meter.

You and a friend play a game where you each toss a balanced coin. If the upper faces on the coins are both tails, you win $1; if
oksian1 [2.3K]

Answer:  The mean and variance of Y is $0.25 and $6.19 respectively.

Step-by-step explanation:

Given : You and a friend play a game where you each toss a balanced coin.

sample space for tossing two coins : {TT, HT, TH, HH}

Let Y denotes the  winnings on a single play of the game.

You win $1; if the faces are both heads

then P(Y=1)=P(TT)=\dfrac{1}{4}=0.25

You win $6; if the faces are both heads

then P(Y=6)=P(HH)=\dfrac{1}{4}=0.25

You loose $3; if the faces do not match.

then P(Y=1)=P(TH, HT)=\dfrac{2}{4}=0.50

The expected value to win : E(Y)=\sum_{i=1}^{i=3} y_ip(y_1)

=1\times0.25+6\times0.25+(-3)\times0.50=0.25

Hence, the mean of Y : E(Y)= $0.25

E(Y^2)=\sum_{i=1}^{i=3} y_i^2p(y_i)\\\\=1^2\times0.25+6^1\times0.25+(-3)^2\times0.5\\\\=0.25+1.5+4.5=6.25

Variance = E[Y^2]-E(Y)^2

=6.25-(0.25)^2=6.25-0.0625=6.1875\approx6.19

Hence, variance of Y = $ 6.19
