Answer:

RS = 4.8

OT = 3.6

From the Pythagorean Theorem we know:

OR^2 = ST^2 + OT^2

OR^2 = 4.8^2 + 3.6^2

OR ^2 = 23.04 + 12.96

OR^2 = 36

OR = 6

Answer:

a. Required system of equations is:

c+p = 10

5c+4p = 46

b. 6 cakes were sold

Step-by-step explanation:

Let p be the number of pies and c be the number of cakes.

Then according to given statement " the store sold 10 baked goods"

c+p = 10\ \ \ Eqn\ 1

And

"A cake costs $5 and a pie costs $4"

5c+4p = 46\ \ \ \ Eqn\ 2

Using equation 1,

c=10-p

Putting this value of c in equation 2:

5(10-p)+4p = 46\\50-5p+4p = 46\\-p = 46-50\\-p = -4\\p = 4

Putting p = 4 in equation 1

c+4 = 10\\c = 10-4\\c =6

Hence,

a. Required system of equations is:

c+p = 10

5c+4p = 46

b. 6 cakes were sold

A Sample Of 100 Clients Of An Exercise Facility Was Selected. Let X- The Number Of Days Per Week That A Randomly Selected Client
julia-pushkina [17]

Answer: 1.013

Step-by-step explanation:

Given the following data :

X_______f___fx___fx²

1_______15__15___15

2______30__60__120

3______28__84__252

4______10__40___160

______ 83__199__547

Number that is 1.5 standard deviations below the mean :

Mean(m) :

Σfx /Σf

(15 + 30 + 28 + 10) / 83

= 199 / 83

= 2.3976

Standard deviation(s) :

Sqrt[(Σfx² - (Σfx)²/Σf) /Σf-1]

sqrt[(547 - (199)²/83) / 83 - 1]

sqrt[(547 - (39601/83) / 82]

sqrt[(547 - 477.12) / 82]

sqrt(0.8522)

Standard deviation = 0.9231

1.5 standard deviations below the mean:

Mean - 1.5(standard deviation)

2.3976 - 1.5(0.9231)

2.3976 -1.38465

= 1.01295

= 1.013
