Determine the slope of the line that passes through the points
(-2, 3) and (2, -4).
Answer:
-7/4
Step-by-step explanation:Slope (m) =
ΔY
ΔX
=
-7
4
= -1.75
θ =
arctan( ΔY ) + 360°
ΔX
= 299.74488129694°
ΔX = 2 – -2 = 4
ΔY = -4 – 3 = -7
Distance (d) = √ΔX2 + ΔY2 = √65 = 8.0622577482985
Equation of the line:
y = -1.75x – 0.5
or
y =
- 7 x

When x=0, y = -0.5
When y=0, x = -0.28571428571429

You are creating identical treat bags using 18 chocolate bars and 30 peanut butter cups. What is the GREATEST number of bags you can fill equally using all the treats? *You will upload a photo of your work for questions 12 and 13 at the end of the test. *
Answer:
The answer is 6.
Step-by-step explanation:
To find the greatest number of bags we can fill equally while using all the treats, we need to find the common denominators of 18 and 30.
After calculating it, we can see that if we fill six bags with both treats distributed equally, we will have used all the treats. 3 chocolate bars and 5 peanut butter cups for each bag.

pls help
im ready to got bed
lol
Answer:
x=-5 Hope this helped! Goodnight!
Step-by-step explanation:
Let's solve your equation step-by-step.
−3(2x+6)=12
Step 1: Simplify both sides of the equation.
−3(2x+6)=12
(−3)(2x)+(−3)(6)=12(Distribute)
−6x+−18=12
−6x−18=12
Step 2: Add 18 to both sides.
−6x−18+18=12+18
−6x=30
Step 3: Divide both sides by -6.
−6x /−6 = 30 /−6
x=-5
Answer:
x= -5

State whether the data described below are discrete or continuous, and explain why.
The exact heights of different elephants. Choose the correct answer below.
A. The data are continuous because the data can take on any value in an interval.
B. The data are discrete because the data can only take on specific values.
C. The data are continuous because the data can only take on specific values.
D. The data are discrete because the data can take on any value in an interval.
Answer:
A. The data are continuous because the data can take on any value in an interval.
Step-by-step explanation:
A continuous data is any data set having infinitely many possible values and those values cannot be counted, meaning they are uncountable. Any quantity such as height, volume, weight, density, length, pressure, temperature, speed, distance, time are generally a continuous data.
Hence, the exact heights of different elephants represents a continuous data because the data can take on any value in an interval.
On the other hand, a discrete data is any data set in which the number of possible values are either finite or countable. Thus, a discrete data can only take on specific values. For example, the value of a fair die, number of sweets in a jar, number of eggs in a crate etc.

Answer:
x = [tex]\frac{-12}{37}[/tex]
or
x = [tex]-\frac{12}{37}[/tex]
Step-by-step explanation:
If you are trying to find x:
1) Go by order of operations (PEMDAS)
217 + 37(3x - 5) = - 4
217 + 111x - 185 = - 4
111x + 217 - 185 = - 4
2) We Want to get 'x' by itself:
111x + 32 = - 4
- 32 = -32
---------------------
111x = - 36
[tex]\frac{111x}{111}[/tex] = [tex]\frac{-36}{111}[/tex]
(Simplify the expression)
x = [tex]\frac{-36}{111}[/tex]
(Both the numerator and denominator can be divided by 3)
x = [tex]\frac{-12}{37}[/tex]
or
x = [tex]-\frac{12}{37}[/tex]
(Both are the same)

What is the slope of the line whose equation is 3x - y = 4?
A -3 B 3 C 3/4 D -3/4
Answer:
Slope =3
Step-by-step explanation:
3x-y=4 Subtract 3x from both sides
-y=-3x+4 Divide both sides by -1
y=3x-4 your slope is the number before the x.

Given the tunction g(x) = 4x - 5, compare and contrast g(2) and g(-4). Choose the statement that is true concerning these two values.
The value of g(2) is larger than the value of g(-4).
The value of g(2) is smaller than the value of g(-4).
The value of g(2) is the same as the value of g(-4).
The values of g(2) and g(-4) cannot be compared.
It takes Deanna seven hours to paint a fence. What fraction of the fence does she paint in one hour?
Answer: 1/7
Step-by-step explanation:
From the question, we are informed that it takes Deanna seven hours to paint a fence. The fraction of the fence does she paint in one hour will be one divided by seven hours which can mathematically be written as:
= 1/7
This means that she'll paint 1/7 of the fence in 1 hour.

Determine whether the given value is a statistic or a parameter. A sample of seniors is selected and it is found that 65% own a television. A. Statistic because the value is a numerical measurement describing a characteristic of a sample. B. Parameter because the value is a numerical measurement describing a characteristic of a sample. C. Statistic because the value is a numerical measurement describing a characteristic of a population. D. Parameter because the value is a numerical measurement describing a characteristic of a population.
Answer: A. Statistic because the value is a numerical measurement describing a characteristic of a sample.
Step-by-step explanation: Statistic are used to describe values obtained from a data sample which are regarded as a subset of the data belonging to an entire population. Therefore, in statistical parlance, numerical measurement obtained from such dataset are called statistic. On the other hand, if data from which a numerical derivation was made is a population which consists of the entire set of observations belonging to a particular group of interest, then the numerical values obtained are referred to as a parameter.
Given: The value [tex]65[/tex]% is a statistic.
The correct option is C (Statistic because the value is a numerical measurement describing a characteristic of a population).
Explanation: We have to determine whether the underlined number is statistics or a parameter.
A sample of employees is selected and it is found that [tex]65[/tex]% own a television.

You have only 1,000$. The price of a TV-set is 1,150$. Can you buy the TV if you get 10% discount?
Answer:
No,I think?
Step-by-step explanation:
Money we have = $1000
Cost of TV set = $1150
10% discount on TV set = $1150 × 10 / 100 (or you can use 10% instead of 10/100)
=$115
Original cost of TV set - 10% of discount on TV set
= $1150 - $115
= $ 1035
since the cost of TV set is greater than the money you have which is (1036 is greater than 1000).You still can't buy the TV set.
