Answer:

In the first one you are missing (x - 3) so it will be 4(x - 3) and if you factor it out it will be 4x - 12

In the second one you are missing a (x -5)which means 9x(x -5) or when you factor it out it will be 9x^2 - 45x

Step-by-step explanation:

3x^2 -23x + 40 = (3x - 8) (x - 5)

3x^2 -17x + 24 = (3x -8) ( x - 3)

Find the probability of obtaining exactly one tail when flipping nine coins. Express your as fraction terms on a rounded the nea

Sveta_85 [38]

Answer:0.017578

Step-by-step explanation:

Given

Nine coins are flipped

So the probability of getting a tail is $\frac{1}{2}$

Because on flipping a coin could either yield Head or tail

so getting a tail on nine trails is $\frac{1}{2^9}$

but this tail can come on first coin or second or third ....

So there are 9 possible ways

So probability of getting a tail on flipping nine coin is $9\times \frac{1}{2^9}$

$=\frac{9}{2^9}=0.017578$

Damien is buying tickets to a movie. The movie he and his friends want to watch cost $4.85 per ticket. Damien has $32.00 total.

skad [1K]

Answer:

Step-by-step explanation:

Setup a equation.

32=4.85x (x equals amount of people)

Then divide both sides.

x=6.60

Obviously you can't split a person into .6, so the greatest amount of tickets is 6

Lily's basketball team won 4/5 of their games. Lily scored points 2/3 of the games her team won. In waht fraction of her team's winning games did Lily score points?

Answer: =D. $\frac{5}{6}$

Solution:

$\frac{ 2 }{ 3 } \div \frac{ 4 }{ 5 } =$

$\frac{2}{3}\times \left(\frac{5}{4}\right)$

$\frac{2\times 5}{3\times 4}$

$\frac{10}{12}$

= $\frac{5}{6}$

I reduced the fraction $\frac{10}{12}$ into the Lowest terms by doing extracting and cancelling out the $2$

= $\frac{5}{6}$

So the answer is letter D. $\frac{5}{6}$

Mariana averaged 80 on her first three math exams. The first score was 86. The second score was 74. What was the third exam scor

Anna71 [15]

The three scores are 86, 74, and an unknown score x. The average (i.e. the sum divided by how many there are) is 80, so we have

$\dfrac{86+74+x}{3}=80$

Multiply both sides by 3 and you get

$160+x=240$

Subtract 160 from both sides to get

$x=240-160=80$

Note: you could solve this exercise very quickly if you notice that the two numbers, 86 and 74, are symmetrical with respect to 80, which is the average. So, the third number must be the average.
