Answer:

M1=108° M2=72°

Step-by-step explanation:

M1 and the original 108° angle are equal, and to calculate M2, which is on the same straight line as the original 108°, we must remember that all angles on a straight line add up to 180°. So, 180-108=72, making M2 72°

8(3x - 6) = 6(x + 8)

24x - 48 = 4x + 48                   Subtract 4x

24x - 4x - 48 = 4x -4x + 48      Combine

20x - 48 = 48                           Add 48 to both sides.

20x = 96                                 divide by 20

x = 96/20

x = 4.8

Answer:

0.1241.

Step-by-step explanation:

So, from the question we are given the following parameters or information or data which are going to help us in solving this particular question/problem. They are; [1]. The critical path for a project = 37 days, the variances total or variance of critical path or sum of variance on critical path]². = 27, the desired completion time/day = 43 days.

So, we will be making use of the formula given below;

The number of standard deviation = desired completion time/day - critical time or sum of critical path times ÷√[variance of critical path or sum of variance on critical path]².

The number of standard deviation = 43 - 37 ÷ √27 = 1.1547.

Thus, the probability of completing in 43 days = P(Z > 1.1547) = 0.1241.

Answer: Ball's kinetic energy became potential energy

Step-by-step explanation:

There are no options attached but this should be along the lines of what happened.

Kinetic energy refers to energy that an object has as a result of it moving whilst potential energy is the opposite and is energy that an object stores within itself due to several factors whilst it is not in motion.

The ball was initially in motion which means that it had kinetic energy but as the ball was slowing down, this energy was gradually converted to potential energy until the balls came to a standstill.

Answer:

Solution: x=5, y=4

Step-by-step explanation:

System of Equations

We need to solve:

- 5x + 9y = 11

x - 3y = - 7

There are several ways to solve a system of linear equations. We'll take advantage of the second equation since it has the x with coefficient 1 and solve it for x:

x = - 7 + 3y

Now replace it into the first equation:

- 5(- 7 + 3y) + 9y = 11

Operate:

35 - 15y + 9y = 11

Simplify:

35 - 6y = 11

Rearrange:

- 6y = 11 - 35 = -24

Solve:

y = -24 / -6

y = 4

Finally, since

x = - 7 + 3y

x = - 7 + 3*4

x = - 7 + 12

x = 5

Solution: x=5, y=4

Answer:

$80 is the 100% original price

The sale price is $56 with 30% off and $24 in savings.

Step-by-step explanation:

We can write a proportion. We know that $24 is a 30% off discount of an unknown original price. Let's call it x. We write equal ratios of  comparing percent and  comparing the 24 to the original price. We then set them equal.

We then cross multiply across the equal sign from numerator to the opposite numerator.

30(x)=24(100)

30x=2400

We divide to find x.

x=80.

Since we saved $24 as a discount, the sale price would be 80-24=56.

Answer:

Piecewise functions are functions that behave differently in different regions of the domain.

One example that you may see in your city is the case of the street illumination, such that can be modeled as:

x = time

Suppose that the lights are turned on at a given hour x0 and then turn off at the hour x1, we can define:

f(x) = 0 if x1 < x < x0

f(x) = 1 if x0 ≤ x ≤ x1

Where f(x) represents the intensity of the light at the time x.

Between x1 and x0, the lights are not working, so the illumination that they provide is zero.

Between x0 and x1 the lights are turned on, so the illumination is 1.

Another example can be the accurate description of the velocity of a car as a function of time.

For some pieces, the car will be stopped (maybe in a red light)

For some pieces, the car will be moving slow (maybe there is a lot of traffic)

For some pieces, the car will be moving fast or accelerating (in an empty street).

So we can define this motion as a piecewise function that obviously will depend on how the car moves.

Answer:

7 inches

Step-by-step explanation:

Given

Shape: Cone

[tex]Volume = 84\pi in^3[/tex]

[tex]Radius = 6in[/tex]

Required

Determine the height

Volume of a cone is:

[tex]V = \frac{1}{3}\pi r^2h[/tex]

Substitute values for volume and radius

[tex]84\pi = \frac{1}{3}\pi * 6^2 * h[/tex]

[tex]84\pi = \frac{1}{3}\pi * 36 * h[/tex]

[tex]84\pi = \frac{36}{3}\pi* h[/tex]

[tex]84\pi = 12\pi* h[/tex]

Solve for h

[tex]h = \frac{84\pi}{12\pi}[/tex]

[tex]h = 7[/tex]

Hence:

The height is 7 inches

Answer:

(a) 3.55

(b) 3.45 and 1.86

(c) 0.25

(d) 0.016

Step-by-step explanation:

The random variable X denotes the number of people in a group (party) at a restaurant.

(a)

The formula to compute the mean is:

[tex]\mu=\sum {x\cdot P(X=x)}[/tex]

Consider the Excel sheet attached.

The mean is, 3.55.

(b)

The formula to compute the variance is:

[tex]\sigma^{2}=[\sum {x^{2}\cdot P(X=x)}]-(\mu)^{2}[/tex]

Consider the Excel sheet attached.

Compute the variance as follows:

[tex]\sigma^{2}=[\sum {x^{2}\cdot P(X=x)}]-(\mu)^{2}\\\\=16.05-(3.55)^{2}\\\\=3.4475\\\\\approx 3.45[/tex]

The variance is, 3.45.

Compute the standard deviation as follows:

[tex]\sigma=\sqrt{\sigma^{2}}\\\\=\sqrt{3.45}\\\\=1.85742\\\\\approx 1.86[/tex]

The standard deviation is, 1.86.

(c)

Compute the probability that the next party will be over 4 people as follows:

[tex]P(X>4)=P(X=5)+P(X=6)+P(X=7)+P(X=8)\\\\=0.10+0.05+0.05+0.05\\\\=0.25[/tex]

Thus, the probability that the next party will be over 4 people is 0.25.

(d)

Compute the probability that the next three parties will each be over 4 people as follows:

It is provided that the three parties are independent.

P (Next 3 parties will be each over 4) = [P (X > 4)]³

                                                           [tex]=(0.25)^{3}\\=0.015625\\\approx 0.016[/tex]

Thus, the probability that the next three parties will each be over 4 people is 0.016.

Answer:

y=3x+1

Step-by-step explanation:

Use the slope formula and slope-intercept form  y = m x + b  to find the equation.

Answer:

(-4,3),(2,-12)

slope = (-12 - 3) / (2 - (-4) = -15/6

Step-by-step explanation:

y = mx + b

slope(m) = -15/6

use either of ur points...(-4,3)...x = -4 and y = 3

now we sub into the formula and find b, the y int

3 = -15/6(-4) + b

3 = 10 + b

3 - 10 = b

-7 = b

so ur equation is : y = -15/6x - 7....but we need it in standard form

y = -15/6x - 7...add 15/6 to both sides

15/6x + y = -7...multiply both sides by 6

15x + 6y = -42....which reduces to 5x + 2y = - 14 <===

Answer:

The amount of money invested at 15% = 30,000

The amount of money invested at 5% = 30,000

Step-by-step explanation:

Calculation for How much money should be invested

Let x dollars = 15%,

Let y dollars= 5%,

x + y = 60,000

0.15x + 0.05y = 6,000

Multiply the 1st Equation by -0.15:

-0.15x - 0.15y = -9,000

0.15x + 0.05y = 6,000

Add the 2 Equations :

-0.1y = -3,000

y=3,000/0.1

y = 30,000

Substitute 30,000 for y in the 1st Equation

x + 30,000 = 60,000

x = 60,000 - 30,000

x= 30,000

PROOF:

.15*30,000+.05*30,000=6,000

4,500+1,500=6,000

6,000=6,000

Hence,

The amount of money invested at 15% = 30,000

The amount of money invested at 5% = 30,000
