Answer:

First place scored 34 points, 2nd place scored 24 points, and 3rd place scored 12 points

Step-by-step explanation:

34 points is 10 points more than 24 points, and 12 points is half of 24 points. Also, 34+24+12=70.

x = player1

y = player 2

z = player 3

y = 2x or 1/2 y =x

y = z-10 or z = y+10

x+y+z=70

substitute x= 1/2 y and z = y+10 into the above equation

1/2y + y + y+10 = 70

2.5 y + 10 = 70

subtract 10 from each side

2.5 y = 60

divide by 2.5 on each side

y = 60/2.5

y =24

x = 1/2 y

x = 1/2 *24 = 12

z = y+10 = 24+10 = 34

The three players scored 12, 24, 34

in a certain recipe, 2 1/4 cups of flour are called for to make a cake that serves 6. of mrs. jenkins wants to use the same reci

Phoenix [80]

If in a certain recipe, a cake serving 6 persons require $2(\frac{1}{2} )$ cups of flour and Mrs. Jenkins wants to use the same recipe to make a cake for 8, then she will need to use $3(\frac{1}{3})$ cups of flour.

As per the question statement, $2(\frac{1}{2} )$ cups of flour are required to bake a cake that serves 6. Mrs. Jenkins wants to use the same recipe to bake a cake for 8.

We have to calculate the number of cups of flours she will need to bake her desired cake as per the same recipe.

To solve this question, we will simply use the unitary method, i.e.,

A cake serving 6 required $2(\frac{1}{2} )=\frac{5}{2}$ cups of flour in its preparation, then,

A cake serving 1 person will require $\frac{\frac{5}{2} }{6} =\frac{5}{12}$ cups of flour, and finally,

A cake serving 1 person will require $(\frac{5}{12} *8)=\frac{10}{3}=3(\frac{1}{3})$ cups of flour.

Hence, Mrs. Jenkins wants to use the same recipe to make a cake for 8, then she will need to use $3(\frac{1}{3})$ cups of flour.

Unitary Method: In Mathematics, the unitary method is a problem-solving technique where, we first find the value of a single unit, and then calculate the necessary value by multiplying that single unit value.

In a study of speed dating, female subjects were asked to rate the attractiveness of their male dates, and a sample of the res

Blizzard [7]

Answer:

hello the data is missing but it is included in the explanation below

missing data = 9, 6, 2, 1, 2, 5, 5, 1, 2, 6, 8, 10, 6, 6, 1, 5, 1, 3, 4, 4, 4, 5, 10, 9, 1, 6

Answer :

A) range = 9 , variance = 8.3015, standard deviation = 2.8812

B) The results cannot be a representative of the variation of attractiveness among the population of adult males

Step-by-step explanation:

A ) calculate the Range, variance and standard deviation

The given data = 9, 6, 2, 1, 2, 5, 5, 1, 2, 6, 8, 10, 6, 6, 1, 5, 1, 3, 4, 4, 4, 5, 10, 9, 1, 6

i) Range = difference between largest and smallest values

= 10 -1 = 9

ii) variance = summation of ; (xi − x)^2/n-1

= 207.5385/26−1 ≈ 8.3015

iii) standard deviation = $\sqrt{variance}$

= $\sqrt{8.3015}$ = 2.8812

B) The results cannot be a representative of the variation of attractiveness among the population of adult males
