Using subtraction, the solution of the given equation is 2.

Subtraction is the process of taking away a number from another. It is a primary arithmetic operation that is denoted by a subtraction symbol (-) and is the method of calculating the difference between two numbers.

= [3 - 8] - [4 - 5 - 6]

= [-5] - [4 - 11]

= -5 - [-7]

= -5 + 7

= 2

Answer:

The firm's fixed-charge coverage ratio is 7.89 times

Explanation:

Fixed charge coverage ratio : This ratio deals with fixed payments like: interest payments, lease payments which is before earning before income and taxes.

The formula to compute the fixed charge coverage ratio is shown below:

= (EBIT + Fixed charges) ÷ (Fixed charges + interest expense)

= ($400,000 + $50,000) ÷ ($50,000 + $7,000)

= $450,000 ÷ $57,000

= 7.89 times

The total of fixed charge include depreciation expense also. Thus it would not be taken into computation part.

Hence, the firm's fixed-charge coverage ratio is 7.89 times

The Limit of g(x) as x approaches 29 is DNE.

A mathematical phrase, rule, or law that establishes the link between an independent variable and a dependent variable (the dependent variable).

We have a function g(x).

In the given table we have different values of x corresponds to g(x).

Now, the value for x= 29 is not given in the table which is not defined.

and, if the value is not defined then it is also infinity.

So, the limit of g(x) tends to 29 is DNE.

Step-by-step explanation:

Because 2 angles in a triangle is not equal, so the 3rd angle cannot be equal.

Answer:

Two angle measures in a triangle are 47 and 43 so the remaining angle is 90 .

so it is a right angled triangle.

Answer:

[tex]P(X\cap Y\cap Z)=0.05[/tex]

Step-by-step explanation:

From the question we are told that:

Percentage of audience in first concert [tex]P(X)=0.28[/tex]

Percentage of audience in second concert [tex]P(Y)=0.42[/tex]

Percentage of audience in third concert [tex]P(Z)=0.30[/tex]

Audience Percentage at at-least one concert [tex]P(X \cup Y \cup Z)=0.80[/tex]

Percentage of audience at first & second concert [tex]P(X \cap Y)=0.10[/tex]

Percentage of audience in first & third concert [tex]P(X \cap Z)=0.08[/tex]

Percentage of audience in second & third concert [tex]P(Y\cap Z)=0.07[/tex]

Generally the equation for probability of attending all concerts [tex]P(X\cap Y\cap Z)[/tex]is mathematically given by

[tex]P(X \cup Y \cup Z)=P(X)+P(Y)+P(Z)-P(X \cap Y)-P(X \cap Z)-P(Y\cap Z)+P(X\cap Y\cap Z)[/tex]

[tex]P(X\cap Y\cap Z)=P(X \cup Y \cup Z)-P(X)-P(Y)-P(Z)+P(X \cap Y)+P(X \cap Z)+P(Y\cap Z)[/tex]

[tex]P(X\cap Y\cap Z)=0.80-0.28-0.42-0.30+0.10+0.80+0.70[/tex]

[tex]P(X\cap Y\cap Z)=0.05[/tex]

Therefore the probability that a randomly selected audient attended all the concerts

[tex]P(X\cap Y\cap Z)=0.05[/tex]

Answer:

[tex] \displaystyle A _{ \text{trapezoid}} = 70 {m}^{2} [/tex]

Step-by-step explanation:

we are given a trapezoid

we want to figure out the area

remember that,

[tex] \displaystyle A _{ \text{trapezoid}} = \frac{a + b}{2} h[/tex]

where a and b represent the parallel lines and h represents the height

we get from the pic that a and b are 5 and 15 respectively and h is 7

so substitute:

[tex] \displaystyle A _{ \text{trapezoid}} = \frac{5 + 15}{2} \times 7[/tex]

simplify addition:

[tex] \displaystyle A _{ \text{trapezoid}} = \frac{20}{2} \times 7[/tex]

simplify division:

[tex] \displaystyle A _{ \text{trapezoid}} = 10\times 7[/tex]

simplify multiplication:

[tex] \displaystyle A _{ \text{trapezoid}} = 70[/tex]

since we multiply two same units we of course have to use square unit

hence,

[tex] \displaystyle A _{ \text{trapezoid}} = 70 {m}^{2} [/tex]

Answer: 4697

Step-by-step explanation:

x + y = 11 ......... i

x² + y² = 325 ........ ii

From equation i

x + y = 11

Therefore, x = 11 - y....... iii

Put equation iii into equation ii

x² + y² = 325

(11 - y)² + y² = 325

(11 - y)(11 - y) + y² = 325

121 - 11y - 11y + y² + y² = 325

121 - 22y + 2y² = 325

121 - 325 - 22y + 2y² = 0

2y² - 22y -204 = 0

2y² - 34y + 12y - 204 = 0

2y(y - 17) + 12(y - 17) = 0

(y - 17) = 0

y = 0 + 17

y = 17

Since x + y = 11

x + 17 = 11

x = 11 - 17

x = -6

Therefore, x³ + y³

= (-6)³ + (17)³

= -216 + 4913

= 4697
