Answer:

x+2/2(2x+1)

Step-by-step explanation:

Tamlin has x male action figures and x + 2 female action figures, so a total of x + x + 2, or 2x + 2 action figures. The probability of picking two female action figures without replacement is equal to the product of the probability of

-picking 1 female action figure from the total number and

-picking 1 female action figure after 1 has been removed.

The probability of picking 1 female action figure from the total is equal to the total number of female action figures divided by the total number of action figures.

The probability of picking 1 female action figure after 1 has been removed is equal to the total number of female action figures minus 1 divided by the total number of action figures minus 1.

Multiply these two expressions and simplify.

scoray [572]

The Solution.

Representing the problem in a diagram, we have

By formula,

P=2(L+W)

In this case,

P=15\operatorname{cm},L=?,W=\frac{22}{8}cm

Substituting these values in the formula above, we get

15=2(L+\frac{22}{8})

Clearing the bracket, we get

15=2L+(2\times\frac{22}{8})\begin{gathered} 15=2L+\frac{11}{2} \\  \\ 15=2L+5.5 \end{gathered}\begin{gathered} 15-5.5=2L \\ 9.5=2L \end{gathered}

Dividing both sides by 2, we get

L=\frac{9.5}{2}=4.75\approx4.8\operatorname{cm}

Therefore, the correct answer is option C.

Flauer [41]
The answer is 5 7/8
b/c 2 1/2 = 2 4/8
so then convert 8 3/8 as an improper fraction which is 67/8
and do the same w/ 2 4/8 which is 20/8
the do: 67/8 - 20/8 = 47/8
simplify 47/8 = 5 7/8.

OlgaM077 [116]

Answer:

(C) The probability of buying bread and cheese is 0.12

Step-by-step explanation:

P(Event A) = 0.6

P(Event B) = 0.2

If Event A and Event B are independent,

Then P(Event A and Event B) = 0.6 x 0.2 = 0.12

I need help 2t<-4 or 7t>49
grin007 [14]
2t<-4 divide both sides by 2

t<-2

...

7t>49  divide both sides by 7

t>7

So t=(-oo,-2) and t=(7,+oo)

t=(-oo,-2)U(7,+oo)

16 miles because first you have to subtract your flat rate of $2 from $10, which will leave you left with $8. If it’s $0.50 per mile then divide that by the amount of money you have remaining after the flat rate deduction (8/0.50). After dividing you will find that you have enough money to travel 16 miles.
