Answer:

I beliive it is 16, but haven't done this in a bit haha

Step-by-step explanation:

So bisect means to "split in half" aka segment BD is directly in the middle of triangle ABC. This means we can look at the half of the triangle we know (ABD). We see a 16, so therefore x should be 16.

(again, hopefully I am correct)

If the annual proportion of erroneous income tax returns filed with the IRS can be looked upon as a random variable having a bet

Volgvan

Answer:

The probability that in any given year there will be fewer than 10 percent erroneous returns is P(x≤0.1)=0.264.

Step-by-step explanation:

For a beta distribution with α = 2 and β = 9, we need to use a calculator to compute the probabilities.

The probability that in any given year there will be fewer than 10 percent erroneous returns is P(x≤0.1)=0.264.

HELP ASAP PLEASE!!!!!!!!!!

14 + 2x = 62 14 - 14 + 2x = 62 - 14. subtract 14 from both sides 2x = 48 48 ÷ 2 = 24. x = 24

20 - 3(3x - 4) <br> Solve the equation

Pavlova-9 [17]

Answer:

32 - 9 x (don't know what you want simplify or solve for x) x = 32/9

Step-by-step explanation:

Simplify the following:

20 - 3 (3 x - 4)

-3 (3 x - 4) = 12 - 9 x:

12 - 9 x + 20

Grouping like terms, -9 x + 12 + 20 = (20 + 12) - 9 x:

(20 + 12) - 9 x

20 + 12 = 32:

Answer: 32 - 9 x

_________________________________

Solve for x:

20 - 3 (3 x - 4) = 0

-3 (3 x - 4) = 12 - 9 x:

12 - 9 x + 20 = 0

Grouping like terms, -9 x + 12 + 20 = (20 + 12) - 9 x:

(20 + 12) - 9 x = 0

20 + 12 = 32:

32 - 9 x = 0

Subtract 32 from both sides:

(32 - 32) - 9 x = -32

32 - 32 = 0:

-9 x = -32

Divide both sides of -9 x = -32 by -9:

(-9 x)/(-9) = (-32)/(-9)

(-9)/(-9) = 1:

x = (-32)/(-9)

Multiply numerator and denominator of (-32)/(-9) by -1:

Answer: x = 32/9

Mr. and Mrs. Romero are expecting triplets. Suppose the chance of each child being a boy is 50% and of being a girl is 50%. Find

Papessa [141]

Answer:

1) $\text{P(at least one boy and one girl)}=\frac{3}{4}$

2) $\text{P(at least one boy and one girl)}=\frac{3}{8}$

3) $\text{P(at least two girls)}=\frac{1}{2}$

Step-by-step explanation:

Given : Mr. and Mrs. Romero are expecting triplets. Suppose the chance of each child being a boy is 50% and of being a girl is 50%.

To Find : The probability of each event.

1) P(at least one boy and one girl)

2) P(two boys and one girl)

3) P(at least two girls)

Solution :

Let's represent a boy with B and a girl with G

Mr. and Mrs. Romero are expecting triplets.

The possibility of having triplet is

BBB, BBG, BGB, BGG, GBB, GBG, GGB, GGG

Total outcome = 8

$\text{Probability}=\frac{\text{Favorable outcome}}{\text{Total number of outcome}}$

1) P(at least one boy and one girl)

Favorable outcome = BBG, BGB, BGG, GBB, GBG, GGB=6

$\text{P(at least one boy and one girl)}=\frac{6}{8}$

$\text{P(at least one boy and one girl)}=\frac{3}{4}$

2) P(at least one boy and one girl)

Favorable outcome = BBG, BGB, GBB=3

$\text{P(at least one boy and one girl)}=\frac{3}{8}$

3) P(at least two girls)

Favorable outcome = BGG, GBG, GGB, GGG=4

$\text{P(at least two girls)}=\frac{4}{8}$

$\text{P(at least two girls)}=\frac{1}{2}$
