The measure of angle fge is 53.13°.

The equation used to find the measure of angle fge is the Law of Cosines. The Law of Cosines states that for any triangle, the square of the length of any side is equal to the sum of the squares of the other two sides, minus twice the product of those sides and the cosine of the angle opposite the side.

Using the Law of Cosines, we can solve for the measure of angle fge as follows:

[tex]fge = cos-1((a^2 + b^2 - c^2) / 2ab)[/tex]

For example, if the length of side a is 3, the length of side b is 4, and the length of side c is 5, then the measure of angle fge can be calculated as follows:

fge =[tex]cos-1((3^2 + 4^2 - 5^2) / 2(3)(4))[/tex]

fge = [tex]cos-1(1/6)[/tex]

fge = 53.13°

[tex]A = P(1 + 0.037t)[/tex]

t = 5 years

[tex]0.037[/tex] is the interest rate per year

[tex]A = P(1 + 0.037t)[/tex]

$[tex]1,422 = P(1 + 0.037\Ttimes 5)[/tex]

If one could fund the entire federal budget by working a single 8-hour work day, approximately 3,085.35 seconds of that working day would be devoted to paying the amount earmarked for public broadcasting.

Scientific notation is a method of writing extremely large or extremely small numbers. When a number between 1 and 10 is multiplied by a power of 10, it is written in scientific notation.

Here,
To put the amount earmarked for public broadcasting into perspective, we can compare it to the total annual federal budget and calculate how much time would be spent working to pay for it.

First, let's convert both amounts to the same unit of measurement, such as dollars per second. If we assume an 8-hour work day,
8 * 60 * 60 = 28,800 seconds,

Then the federal budget can be funded at a rate of,
= 4.75 × 10¹²/ 28,800 seconds
= 165,278.47 dollars per second.

Next, we can divide the amount earmarked for public broadcasting by the rate of funding to find the number of seconds devoted to paying for it,

= 510 × 10⁶ / 165,278.47 dollars per second
= 3,085.35 seconds

Step-by-step explanation:

2.8 is greater than 2.58 - because 2.8 is closer to 3 on the number line.

(a)The probability that the selected individual owns shares in the balanced fund is 8%, that is 0.08.

(b)The probability that the selected individual owns shares in a bond fund is 26%.

(c)The probability that the selected individual does not own shares in a stock fund is 57%.

(a) A probability is a number that indicates how likely an event is to occur. In this case, the event is the selected individual owning shares in the balanced fund. The percentage of customers who own shares in the balanced fund is given as 8%. This means that if 100 customers own shares in just one fund, 8 of them would own shares in the balanced fund.

(b) To find the probability that the individual owns shares in a bond fund, we need to add up the percentages of customers who own shares in each of the bond funds:

Short bond: 14%

Intermediate bond: 7%

Long bond: 5%

Total bond funds: 14% + 7% + 5% = 26%

So, the probability that the selected individual owns shares in a bond fund is 26%.

(c) To find the probability that the selected individual does not own shares in a stock fund, we need to find the complement of the probability that the individual owns shares in a stock fund. The probability that the individual owns shares in a stock fund is the sum of the percentages of customers who own shares in each of the stock funds:

Moderate-risk stock: 25%

High-risk stock: 18%

Total stock funds: 25% + 18% = 43%

So, the probability that the selected individual does not own shares in a stock fund is 1 - 43% = 57%.

The requried expressions that when added together have a sum of -4 n + 6 are -3n - 2 + 7n + 8 and -5n - 1 + 9n + 7.

The equation model is defined as the model of the given situation in the form of an equation using variables and constants.

Here,
We can write two expressions that when added together have a sum of -4n + 6 as follows,

-3n - 2 + 7n + 8

Here, the first expression is -3n - 2, and the second expression is 7n + 8.

When we add these two expressions together, we get:

(-3n) + (7n) + (-2) + 8 = 4n + 6

So the sum of the two expressions is -4n + 6.

Again,
-5n - 1 + 9n + 7

Here, the first expression is -5n - 1, and the second expression is 9n + 7.

When we add these two expressions together, we get:

(-5n) + (9n) + (-1) + 7 = 4n + 6

So the sum of the two expressions is -4n + 6.

Thus, the requried expression that when added together have a sum of -4 n + 6 are -3n - 2 + 7n + 8 and -5n - 1 + 9n + 7.

Exterior angles of a right-angled triangle are calculated by the sum of the opposite interior angles. It can also be calculated by using the sum of angles in a triangle, followed by using the sum of angles on a straight line to determine the exterior angles.

Here, m < 1 = 42°, and the other angle is 90°

Thus, if the sum of the two opposite interior angles equals the exterior angles, then:

m< 2 = 42° + 90°
