Answer:

Step-by-step explanation:

Y-intercept of line is 14

slope of line = (0 - 14)/(10 - 0) = -14/10 = -7/5

Required equation is y = -7/5 x + 14

Answer:

y=3x-4

Step-by-step explanation:

The slope-intercept form of the equation of a line is written in y=mx+b

where m is the slope and b is the y-intercept

So in that form

y=mx+b  becomes

y=3x-4 using your slope of 3 and y-intercept of -4

Answer:

(5a²b^4)³

Step-by-step explanation:

Volume=length*breadth*height

∴Volume=5a²b^4*5a²b^4*5a²b^4

∴Volume of the cube=(5a²b^4)³

Answer:

10 metros.

Step-by-step explanation:

Para determinar la medida de la base de un triángulo que tiene un área de 65 metros cuadrados y una altura de 13 metros se debe realizar el siguiente cálculo, sabiendo que el área de un triangulo es igual a multiplicar su base por su altura, y dividir dicho resultado por 2:

(X x 13) / 2 = 65

X x 13 = 65 x 2

X = 130 / 13

X = 10

Por lo tanto, la base del triángulo es de 10 metros.

Answer:

A refund must be above $7,139 before it is audited.

Step-by-step explanation:

The Empirical Rule states that, for a normally distributed random variable:

Approximately 68% of the measures are within 1 standard deviation of the mean.

Approximately 95% of the measures are within 2 standard deviations of the mean.

Approximately 99.7% of the measures are within 3 standard deviations of the mean.

In this problem, we have that:

Mean = 7010, standard deviation = 43.

Approximately 99.7% of the measures are within 3 standard deviations of the mean.

The empirical rule is symmetric, which means that the lowest (100-99.7)/2 = 0.15% is at least 3 standard deviations below the mean, and the upper 0.15% is at least 3 standard deviations above the mean.

Use the Empirical Rule to determine approximately above what dollar value must a refund be before it is audited.

3 standard deviations above the mean, so:

7010 + 3*43 = 7139.

A refund must be above $7,139 before it is audited.

Answer:

the angle that is 110° and 30°

Step-by-step explanation:

The triangle is similar to triangle T is triangle III.

Thus, option (c) is correct.

In the given triangle,

Two angles are 110 and 40.

Using Angle sum property in given triangles as

Angle 1 + Angle 2 + Angle 3 = 180

110 + 40 + Angle 3= 180

150 + Angle 3= 180

Angle 3 = 180 - 150

Angle = 30

Thus, the angles are 110, 40 and 30.

Therefore, Triangle III is similar to triangle T.

Step-by-step explanation:

A table is a 3-D object. It makes no sense to talk about reflecting it across a point or line. If the table is reflected across a vertical plane, the top will remain "up" and the legs will remain "down".

A glide reflection across a vertical plane will result in a functioning table.

4=x  answer.

Answer:

[tex](a)\ P(x = 0) = 0.2725[/tex]

[tex](b)\ P(x \ge 1) =0.7275[/tex]

[tex](c)\ P(x \le 2) = 0.8948[/tex]

Step-by-step explanation:

Given

[tex]n = 8[/tex] --- 8 friends

[tex]p = 15\%[/tex] --- proportion that one-time fling

This question is an illustration of binomial probability, and it is represented as:

[tex]P(X = x) = ^nC_x* p^x * (1 - p)^{n-x}[/tex]

Solving (a): P(x = 0) --- None has done one time fling

[tex]P(x = 0) = ^8C_0* (15\%)^0 * (1 - 15\%)^{8-0}[/tex]

[tex]P(x = 0) = 1* 1 * (1 - 0.15)^{8}[/tex]

[tex]P(x = 0) = 0.85^8[/tex]

[tex]P(x = 0) = 0.2725[/tex]

Solving (b): [tex]P(x \ge 1)[/tex]

To do this, we make use of compliment rule:

[tex]P(x = 0) + P(x \ge 1) =1[/tex]

Rewrite as:

[tex]P(x \ge 1) =1 - P(x = 0)[/tex]

[tex]P(x \ge 1) =1 - 0.2725[/tex]

[tex]P(x \ge 1) =0.7275[/tex]

Solving (c): [tex]P(x\le 2)[/tex]--- Not more than 2 has one time fling

This is calculated as:

[tex]P(x\le 2) = P(x = 0) + P(x =1) + P(x = 2)[/tex]

We have:

[tex]P(x = 0) = 0.2725[/tex]

[tex]P(x = 1) = ^8C_1* (15\%)^1 * (1 - 15\%)^{8-1}[/tex]

[tex]P(x = 1) = 8* (0.15) * (1 - 0.15)^7[/tex]

[tex]P(x = 1) = 0.3847[/tex]

[tex]P(x = 2) = ^8C_2* (15\%)^2 * (1 - 15\%)^{8-2}[/tex]

[tex]P(x = 2) = 28* (0.15)^2 * (1-0.15)^6[/tex]

[tex]P(x = 2) = 0.2376[/tex]

So:

[tex]P(x\le 2) = P(x = 0) + P(x =1) + P(x = 2)[/tex]

[tex]P(x \le 2) = 0.2725 + 0.3847 + 0.2376[/tex]

[tex]P(x \le 2) = 0.8948[/tex]

========================================================

Explanation:

Angles EGD and BGF are vertical angles. Both are unknown and equal to x.

Notice how angle AGD is adjacent to angle CGD. These two angles form a straight angle (180 degrees) and angle CGD is a right angle. That must mean AGD is also a right angle.

Angles AGE and EGD must add to 90 degrees since AGD is 90

----------

(angleAGE)+(angleEGD) = (angle AGD)

(30) + (x) = 90

x = 90-30

x = 60

Answer:

x=-1 or x=4

Step-by-step explanation:

First divide by 4 to get rid of the factor 4 at x², then you have:

x² - 3x - 4 = 0

to factor that, look for two numbers that when added, give -3, and when multiplied, give -4. This is guesswork but usually doable:

-4 + 1 = -3

-4 * 1 = -4

so -4 and +1 are our numbers.

The factorization is therefore: (x - 4)(x + 1) = 0, and the solutions are

x-4 = 0 or x+1 = 0, so x=4 or x=-1

Answer:

For a height of 66 inches, Z = 0.65.

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

The average height was about 64.3 inches; the SD was about 2.6 inches.

This means that [tex]\mu = 64.3, \sigma = 2.6[/tex]

66 inches:

The z-score for a height of 66 inches is:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{66 - 64.3}{2.6}[/tex]

[tex]Z = 0.65[/tex]

For a height of 66 inches, Z = 0.65.

Answer:

{0} ∈ Z ∧ {0} ∉ N

Step-by-step explanation:

The notations we can use here are:

∈ = belongs

∉ = does not belong.

∧ = and

So, if we want to say that 0 is an integer, we use:

{0} ∈ Z

if we want to say that 0 is not a natural number, we use:

{0} ∉ N

And, if we want to say both in the same statement, we can use the "and" symbol:

{0} ∈ Z ∧ {0} ∉ N

Answer:

140 child tickets, 70 student tickets and 70 adult tickets were sold.

Step-by-step explanation:

Since a theater has tickets at six dollars for adults, three for students and two for children under 12 years old, ya total of 280 tickets were sold for one showing with a total revenue $ 910, if the number of adult tickets plus the number of student tickets was equal to the number of child tickets, to determine how many of each type of ticket were sold for the showing, the following calculation must be performed:

A + S = C

1/2 = 1/2

280/2 = C

140 = C

910 - (140 x 2) = A + S

910 - 280 = A + S

630 = A + S

70 x 6 + 70 x 3 = 630

Therefore, 140 child tickets, 70 student tickets and 70 adult tickets were sold.
