Answer:

12 girls

Step-by-step explanation:

16 divided by 4 is 4

Since the ratio is 4:3, that means that for every 4 boys, there are three girls.

3 x 4 is 12

Data

Number of employees = 192

See the table

Process

a) To solve this question, consider only the employees that prefer a jacket

Male 77

Female +35

112 employees prefer a jacket

- Calculate the probability

P = 112 / 192

P = 0.58

b) Female and prefers a jacket

P = (54 /192)(35/192)

P = (0.28)(0.18)

P = 0.05

You invested $7,000 into a money market account for 10 years at an annual interest rate of 3%. How much is the accrued interest?

steposvetlana [31]

The total interest accrued is $2,407.41 if you invested $7,000 into a money market account for 10 years at an annual interest rate of 3%.

<h3>What is invested amount?</h3>

An investment is a payment made to acquire the securities of other firms with the intention of making a profit.

We are assuming the interest will be compounded annually

$\rm A = P(1+\dfrac{r}{n})^{nt}$

Where A = Final amount

P = Principal amount

r = annual rate of interest

n = how many times interest is compounded per year

t = How long the money is deposited or borrowed (in years)

We have:

P = $7000

r = 3% = 0.03

t = 10 years

n = 1

$\rm A = 7000(1+\dfrac{0.03}{1})^{1\times10}$

After calculating:

A = $9407.41

I = A - P = 9407.41 - 7000 = $2,407.41

Thus, the total interest accrued is $2,407.41 if you invested $7,000 into a money market account for 10 years at an annual interest rate of 3%.

Find the values of x,y,z. This diagram is not a scale.

Serjik [45]

Important:
   The sum of the three angles inside
      every triangle is always 180°.

First, look at the left triangle alone.
Two of its angles are 46° and 58° . (46° + 58° ) = 104°
That leaves (180° - 104° ) = 76° degrees for the third angle.
The third angle in that triangle is 'x'.
   x = 76° .

At the point where 'x' and 'z' come together:
'x' and 'z' are a "linear pair".
Placed side-by-side, they form a straight line.
So (x + z) = 180° .
But x = 76°.
So z = (180° - 76°).    z = 104° .

Now look at the the skinny triangle on the right alone.
The angle at the top is 13°, and z = 104°.
(13° + 104°) = 117° .
That leaves (180° - 117°) = 63° for the third angle.
'y' is the third angle.
   y = 63° .
