A line is decreasing from left to right and crosses the y-axis at-5. Which of the following equations matches the
description of the line?
A. y=5x=5
B. y=-5x-5
C. y=5x -5
D. y=-5x + 5
Answers
Answer:
B
Step-by-step explanation:
y=mx+b is the slope-intercept form. Y will remain the same. Since the slope is decreasing, use a negative. The y-intercept is -5, so substitute that for b.
A large cable company reports the following.
80% of its customers subscribe to its cable TV service.
41% of its customers subscribe to its Internet service.
31% of its customers subscribe to its telephone service.
25% of its customers subscribe to both its cable TV and Internet service.
20% of its customers subscribe to both its cable TV and phone service.
22% of its customers subscribe to both its Internet and phone service.
15% of its customers subscribe to all three services.
Consider the chance experiment that consists of selecting one of the cable company customers at random. Use the probability formulas of this section to find the following probabilities.
a. P(cable TV only)
b. P(Internet I cable TV)
c. P(exactly two services)
d. P(lnternet and cable TV only)
Answers
Answer:
Step-by-step explanation:
Let n(U) be total amount or customers = 100%
n(C) = 80% of its customers subscribe to its cable TV service.
n(I) = 41% of its customers subscribe to its Internet service.
n(T) = 31% of its customers subscribe to its telephone service.
n(CnI) = 25% of its customers subscribe to both its cable TV and Internet service.
n(CnT) = 20% of its customers subscribe to both its cable TV and phone service.
n(InT) = 22% of its customers subscribe to both its Internet and phone service.
n(CnInT) = 15% of its customers subscribe to all three services
number of those that subscribed to TV only = n(C) - (n(CnInT')+(n(CnI'nT)+(n(CnInT))
= 80-[(25-15)+(20-15)+15]
= 80-{10+5+15)
= 80-30
= 50
Hence 50% read cable TV only
Pr(cable TV only) = 50/100 = 1/2
2) number of people that read internet and cable TV = 25%
Pr(internet and cable) = 25/100 = 1/4
3) number of people that had exactly two services are;
n(cable and internet only)+n(internet and phone only)+(cable and phone only)
= (25-15)+(22-15)+(20-15)
= 10+7+4
= 21%
Hence 21℅ read exactly two services
pr(exactly 2 services) = 21/100
4) number of people that read internet and cable only = n(CnI) - n(CnInP)
= 25-15 = 10%
Pr(Internet and cable only) = 10/100 = 1/10

Use cross products to demonstrate whether or not the two ratios are equivalent:
4/6 and 14/21.
Answers
so, essentially you’re just drawing two diagonal lines from one side to the other, multiplying those numbers together, and setting them equal
so: 4/6 and 14/21 = (4*21 = 6*14) = (84 = 84)
84 is equal to 84 so these two ratios are equivalent.

What line is perpendicular to y=2/7x+11/7 travel through (-3,8)
Answers
Answer:
2y- 16 = 7x + 21
Step-by-step explanation:
Y= mX+ c
y = (2/7)x + 11/7
m= gradient= 2/7
The perpendicular gradient should be the negative reciprocal of the gradient we have now.
which is : -1÷(2/7) = -7/2
Now for the perpendicular line equation, we have:
y = 8x= -3m= 7/2y - y1 = m ( x - x1 )
y - 8 = 7/2 ( x + 3 )
2y - 16 = 7x + 21
A table is on sale for 25% off. The original price of the table is $132.00.
What is the discounted price of the table?
$128.00
$33.00
$107.00
$99.00
Answers
Answer:
99%
Step-by-step explanation:
25% of 132 is 33 so 132-33 is $99
Answer: 99
Step-by-step explanation:
turn 25% into a decimal which is .25 and multiply it by 132 to get 33. Thats how much 25% of 132 is so you subtract it to get how much it costs with the sale price.
A club had some money to purchase new chairs. After buying 355 chairs at $199 each, there was $1,068 remaining. How much money did the club have at first? *
Answers
Answer:
$71713
Step-by-step explanation:
If each chair cost $199 then multiple 199 by 355
[tex]199*355= 70645[/tex]
If they still have 1068 then add that into the sum
[tex]70645+1068=71713[/tex]
So your answer is $71713
Answer: $71,713
Step-by-step explanation:
First you would multiply 355 by 199 to get 70,645. Next you would add the remainder of what they had, $1,068, and get the answer. hope this helps.

How much was the initial website fee? (from this equation)
Answers
Answer:
y= .75x + 3.75
Step-by-step explanation:
1. Distribute x:
Original Equation= y-2.25=.75(x-8)
So you just do .75 times x and .75 times -8= .75x - 6
2. Isolate the y Variable:
Add 2.25 to both sides. So -6 + 2.25= 3.75
Now you have left y= .75x + 3.75

Answer:
A triangle with side lengths 4 cm, 5 cm, and 6 cm
A triangle with side lengths 4 cm, 5 cm, and 15 cm
A triangle with side lengths 4 cm and 5 cm and a 50∘ angle
A triangle with angle measures 30 ∘ and 60 ∘ , and a 3 cm side length
Step-by-step explanation:
A triangle measuring 60 ∘, 80∘ and 80∘ is more than sum of angles of a triangle (180∘). This cannot be constructed as triangle because it is more than 180∘.
A triangle can be constructed, If the sum of any two sides is greater than third side,
Thus, a triangle with side lengths 4 cm, 5 cm, and 6 cm can be constructed because;
4 cm + 5cm > 6 cm
A triangle with side lengths 4 cm, 5 cm, and 15 cm can be constructed as well, because;
5 cm + 15 cm > 4 cm
A triangle with side lengths 4 cm and 5 cm and a 50 ∘ angle can be constructed ( two sides and an angle between them)
A triangle with angle measures 30 ∘ and 60 ∘ , and a 3 cm side length can be constructed ( two angles and a side between them)

The population of China is approximately 1.381x10^9, and the population of the US is approximately 3.23x10^8. About how many people live in both countries combined? Answer in scientific notation
Answers
Answer:
1.704 x 10⁹ people
Step-by-step explanation:
Population of China = 1.381 x 10⁹
Population of US = 3.23 x 10⁸
Problem:
Number of people in both countries combined = ?
Solution
To solve this problem, simply add them together;
Let us make the exponents the same for easy addition;
Population of China = 1.381 x 10⁹ = 13.81 x 10⁸
Poplation of US = 3.23 x 10⁸
Adding both:
(13.81 x 10⁸) + (3.23 x 10⁸)
⇒ (13.81 + 3.23) x 10⁸
⇒ 17.04 x 10⁸
⇒ 1.704 x 10⁹
