The probability of spinning an odd number, flipping heads and then spinning a 3 is?
Olenka [21]
<h3>Answer:  5/162</h3>

===================================================

Work Shown:

A = probability of landing on an odd number

A = 5/9 because there are 5 odd numbers out of 9 total

B = probability of getting heads

B = 1/2

C = landing on 3 on the spinner

C = 1/9

Multiply the values of A,B,C

A*B*C = (5/9)*(1/2)*(1/9) = (5*1*1)/(9*2*9) = 5/162

Note: The fraction 5/162 converts to the approximate decimal 0.03086 which then converts to 3.086%, when rounding to the nearest tenth of a percent we get 3.1%

Need help with a and b parts
Masja [62]

Answer:

a)  10/27 or 0.37037

b) -8/7

Step-by-step explanation:

a)  Enter x=-5 into both equations and divide h(-5)/g(-5).  That yields 10/27 or 0.37037037037 . . .

b) g(x) cannot be 0 (can't divide by 0.  That would occur if x = -8/7, so it (-8/7) is not in the domain.

The quotient of b and 2 minus 4 is at least 26. I need this ASAP
Pavlova-9 [17]

For this case we must express the following expression algebraically:

<em>"The quotient of b and 2 minus 4 is at least 26"</em>

So we have to:

The quotient of b and 2 minus 4, is represented as:\frac {b} {2-4}

We have different signs subtracted and the sign of the major is placed:

\frac {b} {- 2}

Thus, the expression is written as:

\frac {b} {2-4} \geq26\\\frac {b} {- 2} \geq26\\- \frac {b} {2} \geq26

ANswer:

\frac {b} {2-4} \geq26
