Answer:

-2.50

Step-by-step explanation:

Using the formula for the expected value, it is found that the expected pay off is of -$1.

In this problem, the outcomes and probabilities are, considering the cost of the game of $5 and that there are 6 sides:

Hence:

[tex]E(X) = \frac{3}{6}(-5) + \frac{2}{6}(2) + \frac{1}{6}(5) = \frac{3(-5) + 2(2) + 1(5)}{6} = -\frac{6}{6} = -1[/tex]

The expected pay off is of -$1.

Answer:

[tex]\frac{5}{12}[/tex]

Step-by-step explanation:

To find a rational number by the mean method.

Add the 2 fractions and divide the result by 2

[tex]\frac{1}{2}[/tex] + [tex]\frac{1}{3}[/tex]

To add the fractions we require them to have a common denominator.

The LCM of 2 and 3 is 6 ← required common denominator

Multiply numerator/denominator of first fraction by 3

Multiply numerator/denominator of second fraction by 2

= [tex]\frac{1(3)}{2(3)}[/tex] + [tex]\frac{1(2)}{3(2)}[/tex]

= [tex]\frac{3}{6}[/tex] + [tex]\frac{2}{6}[/tex] ( add numerators, leaving denominator )

= [tex]\frac{5}{6}[/tex]

Now divide by 2

[tex]\frac{5}{6}[/tex] ÷ 2 leave first, change division to multiplication, turn second upside down )

= [tex]\frac{5}{6}[/tex] × [tex]\frac{1}{2}[/tex]

= [tex]\frac{5}{12}[/tex]

This is the fraction midway between the 2 given fractions

Answer:

2.149 × 10-5

Step-by-step explanation:

Note: Consider the base of all is 3 instead of comma.

Given:

Consider the given value is [tex]\log_37=1.77[/tex].

To find:

The value of [tex]\log_363[/tex].

Solution:

Using properties of logarithm, we get

[tex]\log_363=\log_3(9\times 7)[/tex]

[tex]\log_363=\log_3(3^2\times 7)[/tex]

[tex]\log_363=\log_3(3^2)+\log_3(7)[/tex]       [tex][\because \log ab=\log a+\log b][/tex]

[tex]\log_363=2+ \log_3(7)[/tex]    [tex][\because \log_aa^x=x][/tex]

[tex]\log_363=2+1.77[/tex]        [tex][\because \log_37=1.77][/tex]

[tex]\log_363=3.77[/tex]

Therefore, the value of [tex]\log_363[/tex] is 3.77.

Applying logarithm properties, it is found that:

[tex]\log_3{63} = 3.77[/tex]

We want to find [tex]\log_3{63}[/tex], considering that [tex]63 = 7 \times 9 = 7 \times 3^2[/tex], we have that:

[tex]\log_3{63} = \log_3{(7 \times 3^2)}[/tex]

The first property applied is:

[tex]\log{a \times b} = \log{a} + \log{b}[/tex]

Hence:

[tex]\log_3{63} = \log_3{(7 \times 3^2)} = \log_3{7} + \log_3{3^2}[/tex]

The next property is:

[tex]\log_a{a^b} = b[/tex]

Hence:

[tex]\log_3{7} + \log_3{3^2} = 1.77 + 2 = 3.77[/tex]

4m^2+ 5m +2mn

Step-by-step explanation:

The simplified value of 4m + 2mn + m² + m + 3m² is equal to 4m²+ 5m + 2mn.

The expression given is 4m + 2mn + m² + m + 3m².

We have to simplify the above expression.

What are the variables ?

A variable is a term which represents an unknown number or unknown value or unknown quantity.

As per the question ;

The expression given is 4m + 2mn + m² + m + 3m²

Let's simplify this by adding similar variables ;

4m , m are same variables

i.e., 4m + m = 5m

Similarly ,

m² and 3m² are same variables

i.e., m² + 3m² = 4m²

So ,

The value after simplification will be ;

4m + 2mn + m² + m + 3m²

= 4m²+ 5m + 2mn

Thus , simplified value of 4m + 2mn + m² + m + 3m² is equal to 4m²+ 5m + 2mn.

Answer:

28.76 °F

Step-by-step explanation:

The temperture of sea ice frozen ocean water is about -1.8 °C .

We are to convert to a temperture in fahrenheit using the formula F=(c) (9/5)+32

°C = -1.8°C

°F=(c) (9/5)+32

= [(-1.8°C × 9/5) + 32]°F

= [-16.2/5 + 32]°F

= [-3.24 + 32]°F

Answer:

  45 meters

Step-by-step explanation:

The equation is given in vertex form:

  h(t) = a(t -b)^2 +c

where (b, c) is the vertex (maximum).

The values of the parameters are ...

  a = -5, b = 3, c = 45

Then the maximum height is (time, height) = (3, 45).

The maximum height of the ball is 45 meters.
