I belive,

The experimental probability could be more, the same or less than the theoretical probability of rolling a 1 (which is 1/6).  

The larger your sample (i. e., as you go beyond 60 tosses), the closer the two different probabilities are likely to be.  (Think:  Law of Large Numbers).

Jenny and her children went to the SeaWorld.She purchased adult ticket for herself and children tickets for her 2 boys. Tickets
dangina [55]

Given:

She purchased adult ticket for herself and children tickets for her 2 boys.

Cost of one adult ticket = $39.99

Cost of one child ticket = $19.99

To find:

The expression to represent the total cost of the tickets Jenny purchased.

Solution:

Let x represent the number of adult ticket purchase

and y represent the number of child tickets purchase.

Cost of one adult ticket = $39.99

Cost of one child ticket = $19.99

Total cost = 39.99x + 19.99y

Therefore, the expression for total cost is 39.99x + 19.99y.

She purchased one adult ticket and 2 child tickets.

Substitute x=1 and y=2 in the above expression.

Total cost = 39.99(1) + 19.99(2)

               = 39.99 + 39.98

               = 79.97

Therefore, the required expression to represent the total cost of the tickets Jenny purchased is 39.99(1) + 19.99(2) and total cost is $79.97.

Which property of operations can be used to rewrite the expression without the​ parentheses?
Rus_ich [418]

Answer:

The Commutative Properties of Addition and Multiplication ... in an addition expression can be grouped in different ways without changing the sum. ... Mathematicians often use parentheses to indicate which operation should be done ... Rewrite 7 + 2 + 8.5 – 3.5 in two different ways using the associative property of addition.

Two whole numbers a and b satisfy the following conditions find a and b a b = 30 a:b is equivalent to 2:3
Daniel [21]

Answer:

a=2\sqrt5, b= 3\sqrt5

Step-by-step explanation:

We are given that tow whole number a and b

ab=30

a:b=2:3

We have to find a and b.

ab=30

\frac{a}{b}=\frac{2}{3}

a=\frac{2}{3}b

Substitute the value of a

\frac{2}{3}b\times b=30

\frac{2}{3}b^2=30

b^2=\frac{30\times 3}{2}=45

b=\sqrt{45}=\sqrt{3\times 3\times 5}=\pm3\sqrt5

We take the value of positive because b is a whole number

Substitute the value of b=3\sqrt 5

a=\frac{2}{3}\times 3\sqrt5=2\sqrt5

Hence, a=2\sqrt5, b= 3\sqrt5

A tin has asquare base whose sides measures 32 cm .the vertical sides are 50cm high.cake mixture is poured into the tin and leve
zepelin [54]

Answer:

(a) V = 51200 cubic cm

(b) V' = 38912 cubic cm

(c) V'' = V - V' = 12288 cubic cm

Step-by-step explanation:

side of the square base, s = 32 cm

height, h = 50 cm

height of cake mixture, h' = 38 cm

(a) The capacity of the tin is the volume.  

Capacity of tin, V =  s x s x h = 32 x 32 x 50 = 51200 cubic cm

(b) The volume of the cake mixture is

V' =  s x s x h'

V' = 32 x 32 x 38 = 38912 cubic cm

(c) Volume of unoccupied space is

V'' = V - V' = 51200 - 38912 = 12288 cubic cm
