2 answers:
Answer:
AC = 4.5 units
Step-by-step explanation:
Given question is incomplete without the figure; find the figure attached.
By applying angle bisector theorem in the given triangle ABC,
(Since, AD is the angle bisector of ∠BAC)
AC =
AC = 4.47
AC ≈ 4.5 units
Length of side AC in the given triangle = 4.5 units.

A 2-column table that has 3 rows. The first column is labeled x with entries 0, 1, 2. The second column is labeled P x (x) with entries 0. 25, 0. 5, 0. 25.
<h3>What is Probability?</h3>The probability helps us to know the chances of an event occurring.
We know about the probability, therefore, let's find the probability of each of the cases.
When the number of success of the spinner landing on blue is none, therefore, the spinner does not land on the blue color at all.
Now, as it is given that there is only one case when the spinner does not land on the blue side(RR) in the set, S = {RR, RB, BR, BB}. therefore,
When the number of success of the spinner landing on blue is just once, therefore, the spinner does land on the blue color only once out of the two spin.
Now, as it is given that there are two cases when the spinner does land on the blue side(RB, BR) in the set, S = {RR, RB, BR, BB}. therefore,
When the number of success of the spinner landing on blue is twice, therefore, the spinner does land on the blue color both the times the spinner is spun.
Now, as it is given that there is only one case when the spinner does land on the blue side twice(BB) in the set, S = {RR, RB, BR, BB}. therefore,
Now, if we draw the table of the data and the probability we will get the following table,
x P(X)
0 0.25
1 0.50
2 0.25
Hence, the table that is correct is table A, which is A 2-column table that has 3 rows. The first column is labeled x with entries 0, 1, 2. The second column is labeled P x (x) with entries 0. 25, 0. 5, 0. 25.

Answer:
"She invested $2500 in 5% account and $5500 in 8% account"
Step-by-step explanation:
Let the amount invested in 5% account be "x"
So, the amount invested in 8% account would be "8000 - x"
Interest amount is the percentage multiplied by amount invested. So
Interest of 5% account = 5% of x = 0.05x
Interest of 8% account = 8 % of 8000 - x = 0.08(8000 - x)
Total interest is the sum of these 2 expressions that EQUATES to 565 (given). Let's solve for x:
and thus,
"8000 - x" = 8000 - 2500 = 5500
Hence,
She invested $2500 in 5% account and $5500 in 8% account
