Answer:
Jason started scuba diving 5 meters below sea level and is descending at a rate of 2.5 meters per second.
Step-by-step explanation:
Jason is scuba diving at a constant rate toward the ocean floor.
Equation: [tex]y= -2.5x- 5[/tex]
x = The number of seconds Jason has been swimming.
y=The depth of Jason in meters below sea level
General equation : y=mx+c
m = Slope = rate of change per unit
On comparing m = -2.5
Negative signs represents the descending .
So, rate of descending per second = 2.5 m/sec
-5 denotes the initial position below sea level
So, Option D is true
So, Jason started scuba diving 5 meters below sea level and is descending at a rate of 2.5 meters per second.

Kelly bought a computer that was 20% off the regular price of $1,060. If a 7% sales tax was added to the cost of the computer, what was the total price Kelly paid for it?
Answer: $ 1361.04
Step-by-step explanation:
Discount will be 1060 * 20% = 212
Sales price 1060 + 212 = 1272
Tax 7% = 89.04
Kelly paid 1272 + 89.04 = 1361.04
Language is a complex system that includes the ways we express ourselves, such as speaking or writing, and ways we receive information, such as listening and reading. a. true b. false
Answer: False, language is a more specific word.
Step-by-step explanation:
Language is a complex and structured system of communication.
This word particularly refers to the "artificial codes or ciphers" that humans use to communicate.
The thing in the sentence is more general than language, this refers to communication:
"Communication is a complex system that includes the ways we express ourselves, such as speaking or writing, and ways we receive information, such as listening and reading."
So the actual sentence is false.

Answer:
10 ounces
Step-by-step explanation:
Convert the original container into ounces. (1 quart=32 ounces)
5 x 32 = 160 ounces
Then the milk is divided into two containers.
160 / 2 = 80
Each container is then divided into 8 glasses.
80 / 8 = 10
Each glass has 10 ounces of milk in it.

In the diagram below, the measure of angle 3 is 140, what is the measure of angle 5 ?
I need help with question number 2.
Help me please !
Answer:
2
Step-by-step explanation:
Angles 3 and 5 are alternate interior angles because they are inside the lines and are on opposite sides of the transversal.
This means they are equal to one another, so 2 is correct because they are alternate interior and angle 5 will be 140 degrees.
There are 130 people in a sport centre. 73 people use the gym. 62 people use the swimming pool. 58 people use the track. 22 people use the gym and the pool. 29 people use the pool and the track. 25 people use the gym and the track. 11 people use all three facilities. A person is selected at random. What is the probability that this person doesn't use any facility
To find : Probability that person doesn't use any facility
Given : Total people = 130 ; People using gym (G), Swimming Pool (S), Track (T) = 73, 62, 58 respectively. People using G & P, P & T, G & T = 22, 29, 25. People using P & G & T = 11
So : Prob (G) = 73/ 130 , Prob (S) = 62/130 , Prob (T) = 58/130
P (G ∩ P) = 22 / 130 , P (P ∩ T) = 29 / 130 , P (G ∩ T) = 25 / 130 , P (P ∩ G ∩ T) = 11 / 130
Prob [ Person uses either P or G or T ] :
P (PUGUT) = P(G) + P (S) + P (T) - P (G ∩ P) - P (P ∩ T) - P (G ∩ T) - 2 P (P∩G∩T) = ( 73 + 62 + 58 - 22 - 29 - 25 - 22) / 130 = 95 / 130
Prob [Person uses neither P or G or T] : 1 - Pr [Person uses either P or G or T] = 1 - P (PUGUT) = 1 - (95 / 130) = 35 / 130
Hence, Probability that person doesn't use any facility = 35 / 130

1. Find the simple interest you will obtain if you deposit $600 in bank for 9 months at 4 %per annum.
2. A man walks at a rate of 1.25 / . Find the time he takes to walk 3.75 km.
Answer:
(1) The formula to calculate simple interest (SI), with principal = 600$, annual rate = 4% = 0.04, and time = 9 months is:
SI = principal x rate x time
= 600 x (0.04/12) x 9
= 18$
(2) The formula to calculate the time that man walked 3.75 km, with rate of 1.25:
Time = Distance/Rate
= 3.75/1.25
= 3

En la tienda tienen estas ofertas : 1/4 kg de chorizo : 9,25 €. 1/2 kg de queso : 8,50€.¿Cuánto vale 1 kg de cada producto?¿Cuánto cuesta un queso de 2kg?
Answer: 1. €37 and €17
2. €34
Step-by-step explanation:
Given Data:
Cost of 1/4kg of chorizo = €9.25
Cost of 1/2kg of cheese = €8.50
Therefore:
1. Cost of 1kg of each product.
If 1/4 kg or chorizo cost €9.25,
1kg = 1/4 which is known as one fourth or one quarter. There are 4 one fourth in 1
1kg = 1/4 + 1/4 + 1/4 + 1/4
Or
1kg = 4 * €9.25
1kg = €37
Cost of 1kg of chorizo is €37
Cost of 1kg of cheese
If 1/2kg = €8.50
Then; 1kg = 1/2 + 1/2
1kg = €8.50 + €8.50
1kg = €17
Cost of 1kg of cheese = €17
2. Cost of 2kg of cheese.
If 1kg of cheese cost €17
2kg = 2 * €17
2kg = €34
Cost of 2kg of cheese is €34

Answer:
Since y=x, then both variables must be the same.
-2x + 4y= 16
You have to have 16 on both sides
-2(8) + 4(8)=16
-16 + 32= 16

Find the sum of each infinite geometric series, if it exists
The first series diverges because each successive term is getting multiplied by -3, so the common ratio is larger than 1 in magnitude.
Assuming the second series is
3 - 3/2 + 3/4 - 3/8 + ...
then it converges because the common ratio between terms is -1/2, which is less than 1 in magnitude.
To find the value of the sum, let S denote the n-th partial sum, i.e. the sum of the first n terms in the series:
S = 3 - 3/2 + 3/4 - 3/8 + ... + 3(-1/2)^(n - 2) + 3(-1/2)^(n - 1)
Multiply both sides by -1/2:
(-1/2) S = -3/2 + 3/4 - 3/8 + 3/16 - ... + 3(-1/2)^(n - 1) + 3(-1/2)^n
When we subtract S and (-1/2) S, we see all the middle terms canceling, and we can solve for S:
S - (-1/2) S = 3 - 3(-1/2)^n
S/2 = 3[1 - (-1/2)^n]
S = 6[1 - (-1/2)^n]
As n gets larger, the (-1/2)^n term will converge to 0, leaving us with
lim (n -> infinity) S = 6
so that the series converges to 6.
All else being equal, a study with which of the following error ranges would be
the most reliable?
A. +-6 percentage points
B. +-15 percentage points
C. +-9 percentage points
D.+- 112 percentage points
The study with an error range of +-6 percentage points would be the most reliable.
As larger error ranges, such as options B, C, and D, indicate a greater degree of uncertainty and variability in the dat This reduces the reliability and precision of the study's findings.
So, when all other factors are equal, a study with a smaller error range, like with +-6 percentage points, would be considered more reliable.
Thus, with an error range of +-6 percentage points, has the smallest range.

Note: "difference" means subtraction --> 3x - (-8) --> 3x + 8
23 < 3x + 8 < 32
15 < 3x < 24 subtracted 8 from all 3 sides
