Answer:
D) -3
Step-by-step explanation:
Slope of a linear function:
The slope of a linear function is the amount by which y changes when x increases by 1.
In this question:
When x = 1, y = 12
When x = 2, y = 9
When x = 3, y = 6
When x = 4, y = 3
So each time x increases by 1, y decreases by 3, which means that the slope is -3, and the answer is given by option D.

A cycle wheel has a diameter of 56 cm.
17 Calculate the circumference of the
wheel.
278 Find the distance covered in 100 revo-
lutions.
Formula for circumference is C= πd, meaning pi multiplied by diameter. I will complete the question using both 3.14 for pi, and the pi key on the calculator, as I am not sure what the rules are for your mathematics class.
Formula C=πd, where diameter (given: 56) is 56 and pi is 3.14.
C=πd
= 3.14 x 56
=175.84
∴ The circumference of the wheel is about 175.8cm.
To find how much distance covered in 100 revolutions, we must multiply the distance covered in one revolution by 100.
175.84 x 100= 17584
The question does not ask to convert to meters or kilometers so I may leave it like this.
If you are told otherwise, follow the rules for converting.
∴ The distance covered in 100 revolutions is 17,584cm.
Formula C=πd where d equals 56 and pi is the full value of pi (3.1415926....)
C=πd
= π x 56
=175.929
As you can see, we get a more accurate answer, but again, it is all up to your class rules.
∴ About 175.93 cm circumference
Revolutions:
175.93 x 100 = 17593
∴ About 17, 593cm.

the slope of line p is ___ and the slope of line q is ___
line p
a. -3
b. 1.5
c. 3
line q
a. -3
b. 1.5
c. 3
Answer:
Slope of line p = 3
Slope of line q = -3
Step-by-step explanation:
An easy way to find slope is to pick one point and move up the line to find the next point with exact coordinates.
For line p, we can use point (1,-1). Moving farther up the line, the next point that lands exactly on a coordinate, is (2,2) The slope of a line is the rise of a line over its run. Or, [tex]\frac{rise}{run}[/tex]. From the first point, we move up exactly 3 units, and over 1 unit to reach the next point. We rise 3 units and run 1 unit. In fraction form, [tex]\frac{3}{1}[/tex]. This simplifies to 3. The slope of line p is 3.
----------------------------------------------------------------------------------------------------------------
For line q, we can use the same method. Notice first that the line slopes down, which means the slope will be negative.
Now, we can pick a point on the line. Let's use the same one we used for line p, point (1,-1). The next point up the line is point (0,2). From point (1,-1), we rise 3 units, and run -1 unit. The run, we can tell, is negative, because it goes to the left. The slope is [tex]\frac{3}{-1}[/tex]. Simplify this to -3. The slope of line q is -3.

In a television series there is exactly one crime committed in every episode. It has been observed that the probability that the criminal is male in an episode is 0.35. What is the probability, rounded to three significant figures, that in five consecutive episodes the criminal is a male at least 3 times?
Answer:
[tex]P(x \le 3) = 0.2352[/tex]
Step-by-step explanation:
Given
[tex]p = 0.35[/tex] --- male committing a crime in an episode
[tex]n = 5[/tex] -- Number of episodes
Required
Determine the probability of male committing a crime at least 3 times
This question illustrates binomial distribution and will be solved using;
[tex]P(x) = ^nC_x * p^x * (1 - p)^{n-x[/tex]
So, the required probability is represented as:
[tex]P(x \ge 3)[/tex]
And will be calculated using:
[tex]P(x \ge 3) = P(x = 3) + P(x = 4) + P(x = 5)[/tex]
[tex]P(x = 3) = ^5C_3 * (0.35)^3 * (1 - 0.35)^{5-3}[/tex]
[tex]P(x = 3) = ^5C_3 * (0.35)^3 * (1 - 0.35)^2[/tex]
[tex]P(x = 3) = 10 * (0.35)^3 * (0.65)^2[/tex]
[tex]P(x = 3) = 0.1811[/tex]
[tex]P(x = 4) = ^5C_4 * (0.35)^4 * (1 - 0.35)^{5-4}[/tex]
[tex]P(x = 4) = 5 * (0.35)^4 * (1 - 0.35)^1[/tex]
[tex]P(x = 4) = 5 * (0.35)^4 * (0.65)[/tex]
[tex]P(x = 4) = 0.0488[/tex]
[tex]P(x = 5) = ^5C_5 * (0.35)^5 * (1 - 0.35)^{5-5}[/tex]
[tex]P(x = 5) = 1 * (0.35)^5 * (1 - 0.35)^0[/tex]
[tex]P(x = 5) = 1 * (0.35)^5 * (0.65)^0[/tex]
[tex]P(x = 5) = 1 * (0.35)^5 * 1[/tex]
[tex]P(x = 5) = 0.0053[/tex]
So:
[tex]P(x \ge 3) = P(x = 3) + P(x = 4) + P(x = 5)[/tex]
[tex]P(x \le 3) = 0.1811 + 0.0488 + 0.0053[/tex]
[tex]P(x \le 3) = 0.2352[/tex]

Answer:
She should add 10x to both sides
Step-by-step explanation:
Answer:
Step-by-step explanation:
x² - 10x - 2 = 0 {Add 2 to both sides}
+2 = +2
x² - 10x = 2
Now to find what to add both sides, divide the co-efficient of x by 2
10/2 = 5
Add 5² to both sides
x² - 10x + 25 = 5²
(x - 5)² = 5²
Take square root both sides,
x - 5 = ± 5
x- 5 = 5 ; x - 5 = -5
x = 5+5 ; x = -5 + 5
x = 10 ; x = 0

special right triangle desmo
9514 1404 393
Answer:
x = 15√3
y = 30
Step-by-step explanation:
In a 30°-60°-90° "special" triangle, the ratios of side lengths are ...
1 : √3 : 2
Your diagram shows the short side is 15, so the other sides can be found by multiplying the above ratio numbers by 15.
1 : √3 : 2 = 15 : x : y = 15 : 15√3 : 30
x = 15√3
y = 30

The lowest point in a business cycle, which follows a period of economic
decline, is called a(n)
A. trough
B. contraction
C. peak
D. expansion
The lowest point in a business cycle, which follows a period of economic
decline, is called a trough. Therefore, option A is the correct answer.
What is a period of economic decline?A prolonged period of weak or negative real GDP (output) growth that is accompanied by a noticeably higher unemployment rate is known as a recession. During a recession, a lot of other economic activity indices are similarly weak.
Trough: This refers to the stage of the business cycle when economic activity is at its lowest point.
Expansion: It denotes the period following a dip when overall demand rises. It leads to a rise in output and a decrease in unemployment.
In the business cycle, expansions and contractions alternate (also called recessions).
Recessions frequently begin at the business cycle's high, when an expansion comes to an end, and finish at its trough, when the following expansion starts.
Therefore, option A is the correct answer.
