Answer 1

Supplementary angles have a sum of 180°

Therefore, we can add the expressions for Angles A and B and set their sum equal to 180.

( 7x - 15 ) + ( 2x - 3 ) = 180

Now we can combine like terms and use inverse operations to find the value of x:

( 7x - 15 ) + ( 2x - 3 ) = 180

9x - 18 = 180

9x - 18 + 18 = 180 + 18

9x  = 198

9x/9 = 198/9

x = 22

Then Angle A will have a measure of 7x - 15 or 7• 22 -15 = 154 - 15 = 139°

m∠A = 139°

The measure of Angle b will be 2x - 3 = 2 • 22 - 3 = 44 - 3 = 41°

m∠ B = 41°

NOTE:  139 + 41 = 180

For instance, on the off chance that somebody possesses a vehicle worth $24,000 and owes $10,000 on the credit used to purchase the vehicle, the distinction of $14,000 is value. Value can apply to a solitary resource, like a vehicle or house, or to a whole business.

The solution region for the given pair of inequalities is found to be the common shaded region in the graph attached.

For drawing the graph of any inequality, we first have to assume the inequality as an equation and draw the graph of the resulting equation. Hence, finding the points for the inequality , we let the inequality as:

Putting y=0, we get:

The point will be: (-2,0)

Now, putting x=0, we get:

The point will be: (0,4)

Now as the sign of inequality is >, the line of graph will be dotted.

Taking a test point (0,0) to find the shaded region, substituting this in the inequality,

So, the shaded region will be away from the test point.

Similarly, finding the points for the inequality , we let the inequality as:

Putting y=0, we get:

The point will be: (6,0)

Now, putting x=0, we get:

The point will be: (0,6)

Now, as the sign of inequality is of , the line of graph will be solid.

Taking a test point (0,0) to find the shaded region, substituting this in the inequality,

So, the shaded region will be towards the test point.

The resulting graph is attached after the solution.

The solution to the pair of given inequalities will be the shaded region that is common between both the individual inequality's shaded regions.

The table shows the results of an experiment in which three coins were tossed.
What is the experimental probability that at least two of the coins will be heads? The theoretical probability?

Answers

The experimental probability that at least two heads would be gotten is 11 / 25.

The theoretical probability that at least two heads would be gotten is 1/2.

What are the probabilities?

Probability calculates the odds that a random event would happen. The probability the event occurs is 1 and the probability that the event does not occur is 0.

Experimental probability is based on the result of an experiment that has been carried out multiples times.

Experimental probability = number of times at least two heads would be gotten / total number of tosses

( 5 + 6 + 6 + 5)/50 = 22/50 = 11 / 25

The values of θ, i.e. the general solution of the given trigonometric equation that satisfy the given equation are: 5π/12, π/12.

What is the general solution of a trigonometric equation?

The general solution of a trigonometric equation is a formula employing the integer n that provides all solutions.

Given:

EQuation: 2 cos( 4θ) - 1 = 0.Interval: 0 ≤ θ ≤ π/2

TO find: Values of θ.

Finding:

In the given equation: 2 cos( 4θ) - 1 = 0,

=> cos (4θ) = 1/2

=> cos (4θ) = cos (π/3)

=> 4θ = 2nπ ± π/3

=> θ = nπ/2 ± π/12

For n = 0, θ = ± π/12

For n = 1, θ = π/2 ± π/12

Since θ ∈ [0, π/2],  the possible values of θ = π/12, π/2 - π/12 = 5π/12.

Hence, The values of θ that satisfy the given equation are: 5π/12, π/12.

If the sum of two numbers is 88, then;

x + y = 88

If one number is 4 more than half the other number, then

x = 1/2y + 4

Substitute equation 2 into 1

x + y = 88

(1/2y+4) + y = 88
