The combined average weight of an okapi and a llama is 450 kilograms.
3 llamas, on average, weigh 190 kilograms more than an average okapi.
You want to find the average weight of each type of animal.
Answer:
An average Ilama weighs 160 kilograms and an average okapi weighs 290 kilograms.
Step-by-step explanation:
Let,
x be the average weight of a Ilamas
y be the average weight of an okapi
According to given statement;
x + y = 450 Eqn 1
3x = y + 190 Eqn 2
From Eqn 2
y = 3x - 190 Eqn 3
Putting this value of y in Eqn 1
x + (3x-190) = 450
x + 3x - 190 = 450
4x = 450 + 190
4x = 640
Dividing both sides by 4
[tex]\frac{4x}{4}=\frac{640}{4}\\x=160\\[/tex]
Putting x = 160 in Eqn 3
y = 3(160) - 190
y = 480 - 190
y = 290
Hence,
An average Ilama weighs 160 kilograms and an average okapi weighs 290 kilograms.

Isabel Briggs Myers was a pioneer in the study of personality types. The personality types are broadly defined according to four main preferences. Do married couples choose similar or different personality types in their mates? The following data give an indication.
Similarities and Differences in a Random Sample of 375 Married Couples
Number of Similar Preferences Number of Married Couples
All four 30
Three 128
Two 124
One 61
None 32
Suppose that a married couple is selected at random.
(a) Use the data to estimate the probability that they will have 0, 1, 2, 3, or 4 personality preferences in common. (Enter your answers to 2 decimal places.)
0 1 2 3 4
1 2 3 4 5
(b) Do the probabilities add up to 1? Why should they?
i. Yes, because they do not cover the entire sample space.
ii. No, because they do not cover the entire sample space.
iii. Yes, because they cover the entire sample space.
iv. No, because they cover the entire sample space.
(c) What is the sample space in this problem?
i. 0, 1, 2, 3 personality preferences in common
ii. 1, 2, 3, 4 personality preferences in common
iii. 0, 1, 2, 3, 4, 5 personality preferences in common
iv. 0, 1, 2, 3, 4 personality preferences in common
Answer:
a. Probability (0) = 36/375 = 0.096
Probability (1) = 61/375 = 0.162
Probability (2) = 124/375 = 0.330
Probability (3) = 128/375 = 0.341
Probability (4) = 30/375 = 0.08
b. iii) Yes, because they cover the entire sample space.
c. Obviously, the sample space in this problem is iv.
iv = {0,1,2,3,4} personality preferences in common.
Step-by-step explanation:
In this question, we are asked to calculated the probability of preferences in common.
As we know, the general formula for probability is:
Probability = Number of favorable outcome/ Total number of favorable outcomes
Data Given:
For 0 = 36
For 1 = 61
For 2 = 124
For 3 = 128
For 4 = 128
Total = 375 Married Couples
Probability (0) = Number of favorable outcomes/ Total Number of Favorable outcomes
Probability (0) = 36/375 = 0.096
Similarly,
Probability (1) = 61/375 = 0.162
Similarly,
Probability (2) = 124/375 = 0.330
Similarly,
Probability (3) = 128/375 = 0.341
Similarly,
Probability (4) = 30/375 = 0.08
b. Total Probability can never be greater than 1 and less than 0.
So, Probabilities of the sample will add up to 1
iii) Yes, because they cover the entire sample space.
Total Probability = P(0) + P(1) + P(2) + P(3) + P(4) = 1
Total Probability = 0.09 + 0.16 + 0.33 + 0.34 + 0.08 = 1
c. Obviously, the sample space in this problem is iv.
iv = {0,1,2,3,4} personality preferences in common.

In the accompanying diagram, transversal EF intersects parallel lines AB and CD at G and H, respectively. If m∠EGB = 2x + 40 and m∠FHC = 3x - 10, what is the value of x
No diagram is provided but we can still work it out (it may vary).
So the from the description, we can tell that m∠EGB = m∠FHC through alternate exterior angles.
So,
m∠EGB = 2x + 40
m∠FHC = 3x - 10
m∠EGB = m∠FHC
2x + 40 = 3x - 10
40 = 3x - 2x - 10
40 = x - 10
40 + 10 = x
50 = x
x = 50
The value of x is 50

What is area?An area is total space occupied by two-dimensional or flat surfaces. In other words we can say that it is a number of unit squares present in a closed figure. We use various units for measurement of area like, cm², m², ft², mm².
Area of square = a²
Area of rectangle = a × b
Area of circle = πr²
Given that,
The dimensions of the room are 200 feet by 180 feet
Each bottle of carpet shampoo can be used to shampoo 320 square feet of carpet
bottles of shampoo = ?
Total area we need to clean = 200 × 180
= 36000
one bottle can clean area = 320 square feet
number of bottles = Total area /one bottle can clean
number of bottles = 36000/320
= 112.5
≈ 113 bottles
So, The number of bottles required is 113

Abigail wants to ride her bicycle 30.4 miles this week. She has already ridden 7 miles.
If she rides for 3 more days, write and solve an equation which can be used to
determine m, the average number of miles she would have to ride each day to meet
her goal.
Answer:
3m + 7 = 30.4
m = 7.8
Step-by-step explanation:
3m, where m is the average number of miles per day, will represent how many miles she rides in the next 3 days.
She has already ridden 7 miles, so 7 has to be added to 3m in the equation.
Then, the equation has to be set equal to 30.4, because that is her goal for the week
Put this all together:
3m + 7 = 30.4
Solve for m:
3m + 7 = 30.4
3m = 23.4
m = 7.8
So, Abigail has to ride an average of 7.8 miles per day to meet her goal.

2. 57.14, 5.714, .5714
Step-by-step explanation:
Answer:
Step-by-step explanation:
1.
1.365 x 10^1 = 13.65
1.365 x 10^2 = 136.5
1.365 x 10^3 = 1365
2.
571.4 / 10^1 = 57.14
571.4 / 10^2 = 5.714
571.4 / 10^3 = 0.5714
3.
479 x 10^(-1) = 4.79 * 10^1 = 47.9
479 x 10^(-2) = 4.79 * 10^0 = 4.79
479 x 10^(-3) = 4.79 * 10^(-1) = 0.479
4.
89.15 x 10^3 = 8.95 * 10^4 = 89500
5.
217.5 / 10^2 = 2.175
6.
I can't see if that is a comma or period, so I will do both
4,000 x 10^(-3) = 4 * 10^(0) = 4
4.000 x 10^(-3) = 4 * 10^(-3) = 0.004
7.
89.25 / 10^1 = 8.925
8.
3.107 x 10^1 = 31.07
9.
45.2 / 10^3 = 0.0452
10.
2,100 x 10^(-2) = 2.1 * 10^1 = 21
11.
5.7 / 10^3 = 0.0057
12.
I can't see if that is a 2 or 3, so I will do both. Standard form refers to the usual way that numbers are written. Power to the 3 means move the decimal right 3 places, while power to the 2 means move the decimal right 2 places.

Part A: A graph passes through the points (0, 2), (1, 3), and (2, 4). Does this graph represent a linear function or a non-linear function? Explain your answer in words
Part B: Write one example of a linear function and one example of a non-linear function.. (Use x and y as the variables) (10 points)
Answer:
Part A:
The graph passes through (0,2) (1,3) (2,4).
If the graph that passes through these points represents a linear function, then the slope must be the same for any two given points. Using (0,2) and (1,3). Write in slope-intercept form, y=mx+b. y=x+2
Using (0,2) and (2,4). Write in slope-intercept form, y=mx+b. y=x+2. They are the same and in graph form, it gives us a straight line.
Since the slope is constant (the same) everywhere, the function is linear.
Part B:
A linear function is of the form y=mx+b where m is the slope and b is the y-intercept.
An example is y=2x-3
A linear function can also be of the form ax+by=c where a, b and c are constants. An example is 2x + 4y= 3
A non-linear function contains at least one of the following,
*Product of x and y
*Trigonometric function
*Exponential functions
*Logarithmic functions
*A degree which is not equal to 1 or 0.
An example is...xy= 1 or y= sqrt. x
An example of a linear function is 1/3x = y - 3
An example of a non-linear function is y= 2/3x
