Answer:

m∠QPR = 20°

Step-by-step explanation:

Step 1: Find x

4x + 27 + 9x - 115 = 107

13x - 88 = 107

13x = 195

x = 15

Step 2: Find m∠QPR

9(15) - 115

135 - 115

m∠QPR = 20°

To find the intersection point between the curve y = tan(x) and the line y = 7x, we can use Newton's method. Newton's method is an iterative numerical method used to approximate the root of a function.

We need to find the x-value where the curves intersect, so we can set up the equation tan(x) - 7x = 0. We want to find a solution between x = 0 and some unknown value denoted as X.

Using Newton's method, we start with an initial guess x_0 for the solution and iterate using the formula:

x_(n+1) = x_n - f(x_n) / f'(x_n),

where f(x) = tan(x) - 7x and f'(x) is the derivative of f(x).

We continue this iteration until we reach a desired level of accuracy or convergence. The resulting value of x will be the approximate intersection point between the two curves.

Please note that without specific values or range for X or an initial guess x_0, it is not possible to provide a specific numerical answer. However, you can apply Newton's method using an initial guess and the given function to find the approximate intersection point.

Answer:

25%

Step-by-step explanation:

U flipped a coin 12 times, it lands on tail 9 times. Now the probability of landing on head = 12-9

= 3

In percentage= 12\3 *100

=25%

Answer:

0.25%

Step-by-step explanation:

The definition of percent helps you write fraction and decimal equivalents by understanding that "per cent" means "per hundred".

For example, if you are asked to write the fraction and decimal equivalent of 25%, you would divide 25 by 100 to get the fractional equivalent of ¼, and divide 25 by 100 to get the decimal equivalent of 0.25.

The decimal equivalent of a fraction or percentage is the numerical value expressed in decimal form. For example, the decimal equivalent of 1/2 is 0.5 and the decimal equivalent of 25% is 0.25. Decimal equivalents are useful for calculations and can be used to convert fractions and percentages into decimal form.

Answer:

1/24

Step-by-step explanation:

We can't subtract two fractions with different denominators. So you need to get a common denominator. To do this, you'll multiply the denominators times each other... but the numerators have to change, too. They get multiplied by the other term's denominator.

So we multiply 11 by 8, and get 88.Then we multiply 7 by 12, and get 84.

Next we give both terms new denominators -- 12 × 8 = 96.

So now our fractions look like this:

88 /96 -84 /96

Step 2

Since our denominators match, we can subtract the numerators.

88 − 84 = 4

So the answer is:

4 /96

Step 3

Last of all, we need to simplify the fraction, if possible. Can it be reduced to a simpler fraction?

To find out, we try dividing it by 2...

Are both the numerator and the denominator evenly divisible by 2? Yes! So we reduce it:            

4 /96 ÷ 2 =2 /48

Let's try dividing by 2 again...

Are both the numerator and the denominator evenly divisible by 2? Yes! So we reduce it:

2 /48 ÷ 2 =1 /24

Let's try dividing by 2 again...

No good. 2 is larger than 1. So we're done reducing.                                    There you have it! The final answer is:

Deb gets paid $153 for cleaning a building half the size, which is 4550 square feet.

To find the amount Deb gets paid for a building half the size, first, we need to calculate the square footage of the smaller building and then set up a ratio.

Step 1: Calculate the square footage of the smaller building.

The smaller building has half the square footage of the 9100 square foot building. So, divide 9100 by 2:

9100 ÷ 2 = 4550 square feet.

Step 2: Set up a ratio to find the cost of cleaning the smaller building.

Let x be the cost of cleaning the 4550 square foot building. We can set up a ratio comparing the cost of cleaning the 9100 square foot building to the cost of cleaning the 4550 square foot building:

$306 / 9100 = x / 4550

Step 3: Solve for x.

To solve for x, cross-multiply:

9100 * x = 306 * 4550

Then divide by 9100:

x = (306 * 4550) / 9100

x = 153

So, Deb gets paid $153 for cleaning a building half the size, which is 4550 square feet.

The probabilities of events A ∩ B, A ∪ B, and A ∩ B^c, assuming all 36 sample points have equal probability, are 1/2, 5/6, and 1/4, respectively.

Let's analyze the events described:

Event A: The sum of the faces is odd.

Event B: At least one ace (one comes up).

To describe the events A ∩ B, A ∪ B, and A ∩ B^c, we need to understand the outcomes that satisfy each event.

Event A ∩ B: The sum of the faces is odd and at least one ace comes up. This means we want the outcomes where the sum is odd and there is at least one 1 on either die.

Event A ∪ B: The sum of the faces is odd or at least one ace comes up. This includes the outcomes where either the sum is odd, or there is at least one 1.

Event A ∩ B^c: The sum of the faces is odd, but no aces (1) come up. This means we want the outcomes where the sum is odd and neither die shows a 1.

To find the probabilities of these events, we need to count the favorable outcomes and divide by the total number of possible outcomes.

There are 36 possible outcomes when two dice are thrown (6 possible outcomes for each die)

The favorable outcomes for each event can be determined as follows:

Event A ∩ B: There are 18 favorable outcomes. There are 9 outcomes where the sum is odd (1+2, 1+4, 1+6, 2+1, 2+3, 2+5, 3+2, 4+1, 6+1) and another 9 outcomes where there is at least one ace (1+2, 1+3, 1+4, 1+5, 1+6, 2+1, 3+1, 4+1, 5+1).

Event A ∪ B: There are 30 favorable outcomes. There are 18 outcomes where the sum is odd (as mentioned above) and an additional 12 outcomes where there is at least one ace (1+2, 1+3, 1+4, 1+5, 1+6, 2+1, 3+1, 4+1, 5+1, 6+1, 1+6, 2+6).

Event A ∩ B^c: There are 9 favorable outcomes. These are the outcomes where the sum is odd and neither die shows a 1 (1+3, 1+5, 2+3, 2+5, 3+2, 3+4, 4+3, 4+5, 5+3).

Finally, we can calculate the probabilities by dividing the number of favorable outcomes by the total number of outcomes (36):

P(A ∩ B) = 18/36 = 1/2

P(A ∪ B) = 30/36 = 5/6

P(A ∩ B^c) = 9/36 = 1/4

Therefore, the probabilities of events A ∩ B, A ∪ B, and A ∩ B^c, assuming all 36 sample points have equal probability, are 1/2, 5/6, and 1/4, respectively.

The present value of a cash inflow of 1250 four years from now, given a required rate of return of 8%, is 918.79, rounded to 2 decimal places. Therefore, option (c) is the correct answer.

To find the present value of a future cash inflow, we need to discount the future value by a factor that takes into account the time value of money, or the opportunity cost of waiting for the money.

This factor is determined by the required rate of return, which is the minimum rate of return that an investor expects to earn on an investment with a similar level of risk.

In this case, we have a cash inflow of 1250 that will be received four years from now, and a required rate of return of 8%. To find the present value, we can use the formula for the present value of a single cash flow:

PV = FV / (1 + r)^n

where PV is the present value, FV is the future value, r is the required rate of return, and n is the number of years.

Plugging in the values, we get:

PV = 1250 / (1 + 0.08)^4

PV = 918.79

Therefore option (c) is the correct answer.

The value of k that will make the quadratic equation kx² - 4x + 1 = 0 to have two equal roots is; k = 4

The general form of representing a quadratic equation is;

Now, we are given the quadratic equation which is;

kx² - 4x + 1 = 0

Now, for a quadratic equation to have 2 equal roots, it means that;
