Answer:

m∠D = 49°
m∠E = 41°
m∠F = 90°

Step-by-step explanation:

        We know a triangle's angles add up to 180, so we can create an equation and solve for x. We also know the little box represents 90 degrees.

Given:

        90° + 5x° + 14° + 3x° + 20° = 180°

Combine like terms:

        8x° + 124° = 180°

Subtract 124 from both sides of the equation:

        8x° = 56°

Divide both sides of the equation by 8:

        x = 7

        Now, we will plug this value of x back into the angles to solve. Again, the little box represents that Angle F is equal to 90 degrees.

m∠D = 5x° + 14° = 5(7)° + 14° = 49°
m∠E = 3x° + 20° = 3(7)° + 20° = 41°
m∠F = 90°

The value of α = 0.26 finding by using normal distribution.

A normal distribution is an arrangement of a data set in which most values cluster in the middle of the range and the rest taper off symmetrically toward either extreme.

Given that,

confidence level = 74%

alpha = ?

The significance level α is the probability of making the wrong decision when the null hypothesis is true. Alpha levels which is also called as significance levels are used in hypothesis tests.

Mathematically, the value of α is determined by subtracting the level of confidence from 1, and then writing the result as a decimal.

As the confidence level is given as 74%, so the significance level would be,

α  = 1 - confidence level

 =  1 - 0.74

α = 0.26

Hence, The value of α = 0.26.

Answer:

Okay bestie ‼️

Step-by-step explanation:

Answer:

y = -x + 2

Step-by-step explanation:

[slope-intercept form] y = mx + b

m [slope] = ∆y/∆x = y₂–y₁ / x₂–x₁

b [y-intercept] = (0,b) → x = 0.

If y = 2 when x = 0, b = 2.

Since y decreases by 1 unit everytime x increases by 1 unit

a decrease by 1 unit is represented by -1, and an increase of 1 is represented by 1.

So a decrease of -1 over an increase of 1

is -1/1 = -1 = m.

The measure of angle A is 21.75°. Therefore, option 3 is the correct answer.

Law of Sines In trigonometry, the law of sines, sine law, sine formula, or sine rule is an equation relating the lengths of the sides of any triangle to the sines of its angles.

The formula for sine rule is sinA/a=sinB/b=sinC/c

From the given triangle ABC, BC=19 units, AC=43 units and ∠B=123°.

Using sine rule,

sinA/19 =sin123°/43

sinA/19 = 0.8386/43

sinA/19 = 0.8386/43

sinA/19 = 0.0195

sinA=0.0195×19

sinA=0.3705

A=21.75°

Answer:

m∠Q = 121°

m∠R = 58°

m∠S = 123°

m∠T = 58°

Step-by-step explanation:

The sum of the interior angles of a quadrilateral = 360°

Create an expression for the sum of all the angles and equate it to 360, then solve for x:

      ∠Q + ∠T + ∠S + ∠R = 360

⇒ 2x + 5 + x + 2x + 7 + x = 360

⇒ 6x + 12 = 360

⇒ 6x = 360 - 12 = 348

⇒ x = 348 ÷ 6 = 58

So now we know that x = 58, we can calculate all the angles:

m∠Q = 2x + 5 = (2 x 58) + 5 = 121°

m∠R = x = 58°

m∠S = 2x + 7 = (2 x 58) + 7 = 123°

m∠T = x = 58°

Weak negative association

Step-by-step explanation:

A scatter plot shows the relationship between two variables. The relationship between variables could be;

i) Strong positive association

ii) Strong negative association

iii) Weak positive association

iv) Weak negative association

If the line descends from left to right as stated in the question, it denotes a negative relationship.

The fact that data points are gathered loosely around this line means that the relationship is weak.

Hence the plot shows a weak negative association

The length of the garden is 99 m.

The formula for the area of a rectangle is:

Area = Length x Width

We are given that the area of the rectangle is 8811 \(m^{2}\) and the width is 89 m. Substituting these values into the formula, we get:

8811 \(m^{2}\) = Length x 89 m

To solve for the length, we can divide both sides of the equation by 89 m:

Length = 8811 \(m^{2}\) / 89 m

Simplifying, we get:

Length = 99 m

Therefore, the length of the garden is 99 m.

13. The nth term of the given sequence is ∂n = (2n-1)/n².

14. The nth term of the given sequence is ∂n = (n + 7)/(n + 8).

13. The given sequence is defined by ∂n = (2n-1)/n². This is a fractional sequence where the numerator increases by 2 for each term and the denominator is the square of the term number n.

The nth term is represented by ∂n = (2n-1)/n². For example, when n = 1, the first term is ∂1 = (2(1)-1)/(1²) = 1/1 = 1.

Similarly, for n = 2, the second term is ∂2 = (2(2)-1)/(2²) = 3/4.

Therefore, the nth term of the sequence is given by ∂n = (2n-1)/n².

14. The given sequence has a pattern where the numerator starts at 7 and increases by 1 for each term, while the denominator starts at 8 and increases by 1 for each term.

The nth term can be represented as ∂n = (n + 7)/(n + 8).

For instance, when n = 1, the first term is ∂1 = (1 + 7)/(1 + 8) = 8/9.

Similarly, for n = 2, the second term is ∂2 = (2 + 7)/(2 + 8) = 9/10.

Hence, the nth term of the sequence is given by ∂n = (n + 7)/(n + 8).

3x4 = 12

1x4 = 4

now the equation is \(9+12 - 4\)

9+12 = 21

that makes the equation 21-4

21-4 = 17

a) 17

now for b

b)

the equation would then be \(9+3 x (2^{2} - 1) x 4\)

so youd use pemdas as always

the equation is now \(9+3 x 3 x 4\)

Step-by-step explanation:

press the picture to see the answer I swear it has a solution too

The required rate of return (or minimum acceptable rate of return) is 20 percent. If the net cash flows are $15,000 per year for ten years, the total cash flow is $150,000. The project's cost is $47,500. We can now apply the net present value formula to determine whether or not the project is feasible.

Net Present Value (NPV) = Cash flow / (1 + r)^n - Cost Where, r is the discount rate, n is the number of years, and Cost is the initial outlay.

Net Present Value = 150000 / (1 + 0.20)^10 - 47500

Net Present Value = $67,482.22

Since the NPV is positive, the project is feasible. When calculating net present value, it's important to remember that a positive NPV implies that the project is expected to generate a return that exceeds the cost of capital, whereas a negative NPV indicates that the project is expected to generate a return that is less than the cost of capital, and as a result, it should be avoided.
