Answer:
D
Step-by-step explanation:
The amount of oil and natural gas a given region produces is not always proportionate to the size of its proven reserves. For example, the Middle East contains approximately 50 percent of the world’s proven reserves but accounts for only about 30 percent of global oil production (though this figure is still higher than in any other region). The United States, by contrast, lays claim to less than 2 percent of the world’s proven reserves but produces roughly 16 percent of the world’s oil.
At the organic produce store you can buy 3 bags of sweet potatoes for $20.07.
How much would it cost if you were to buy only 2 bags.
Answer:
$13.38
Step-by-step explanation:
Use proportions to solve this problem:
$20.07 / 3 bags = X / 2 bags
multiply both sides by "2 bags" to isolate the unknown X
$20.07 * 2 / 3 = X
Therefore, X = $13.38
two balls are chosen randomly from an urn containing 5 white, 3 black, and 2 orange balls. suppose that you win $2 for each black ball selected and you lose $1 for each white ball selected. what is the expected amount you will win from this game
Answer:
2.601
Step-by-step explanation:
Given that:
White balls, W = 5
Black balls, B = 3
Orange balls, O = 2
Total = (5 + 3 + 2) = 10
Winning = $2 for each black ball chosen
Winning = - $1 for each white ball
Sample space for making 2 selections ; order does not matter :
{WW, WO, WB, OO, OB, BB}
WW __WO __WB __OO ___OB __BB
-2 ____ - 1 __ 1 ____ 0 ____ 2 ___ 4
WW = 5C2 / 10C2 = 0.2222
WO = (5C1 * 2C1) / 10C2) = 0.222
WB = (5C1 * 3C1) / 10C2) = 0.3333
OO = (2C2) / (10C2) = 0.0222
OB = ((2C1) * (3C1)) / 10C2 = 0.1333
BB = 3C2 / 10C2 = 0.0667
Expected winning = Σx * p(x)
(-2 * 0.222) + (-1 * 0.222) + (1 * 0.333) + (0 * 0.022) + (2 * 0.133) + (4 * 0.667)
= 2.601
Solve for a.
4/a+4 =-1/a+9
Answer:
a = -8
Step-by-step explanation:
you can solve this proportion by cross-multiplying:
4(a + 9) = -1(a + 4)
now distribute to eliminate parentheses
4a + 36 = -1a - 4
5a + 36 = -4
5a = -40
a = -8
100 points I need help
Answer:
D is located at (-5, 2)
Answer:
point D
Step-by-step explanation:
(-5, 2) can be represented as (x, y)
This mean when x = -5, y is = 2
We need to trace the x-axis to -5 and get the corresponding point at y equals to 2
Tracing the point on the graph, we find the point D is at x = -5 and y = 2
Hence, point D is located at (-5, 2)

Can someone tell me how to figure this out and the answer. (Brainliest I can give)
9514 1404 393
Answer:
x/50 = 40/100
x = 20
Step-by-step explanation:
It is useful to remember that the symbol % is a shorthand way to write /100. (Similarly, the symbol ‰ is a shorthand way to write /1000.) This means the number 40% represents the ratio 40/100. In decimal, that is 0.40 (forty hundredths).
When this is the fraction that represents the number of test questions that are correct, you can see that the proportion should be ...
correct / total questions = x / 50 = 40 / 100 . . . . the desired proportion
Multiplying by 50 gives the value of x:
x = 50(0.40)
x = 20 . . . . the value of x

WRITE A SHORT STORY WITH A SYMBOL THAT IS A CENTRAL PLOT A CONFLICT AND A CONCLUSION MAKE SURE THE STORY HAS CHARACTERS, DIALOGUE AND SETTING
BE CREATIVE AND EXPLORE YOUR IMAGINATION MUST BE 3 PARAGRAPHS
Answer:
I don't believe this is a mathematics related question....
Step-by-step explanation:
Don't have someone write this for you though, this sounds like a fun assignment. If you need help with the terms
Central plot = what is happening. Is a king trying to fight off a dragon? A penguin trying to learn to hunt?
Conflict = what goes wrong to make the goal harder.
Conclusion = How it ends.
Characters = People or creatures in the story.
Dialogue = What people are saying.
Setting = When and where the story takes place.

A pet store has 9 puppies, including 2 poodles, 2 terriers, and 5 retrievers. If Rebecka and Aaron, in that order, each select one puppy at random with replacement (they may both select the same one), find the probability that Rebecka selects a terrier and Aaron selects a retriever.
Answer:
5/162
Step-by-step explanation:
Probability of getting terrier = 2/18 = 1/9
Probability of getting retriever = 5/18
5/18 x 1/9 = 5/162

Robin braided g inches of a friendship bracelet. Olivia braided 12 less than 1/3 the number of inches robin braided. Select all of the expressions that represent the total number of inches braided by robin and Olivia
I NEED DONE ASAP PLEASEEE
Answer:
Step-by-step explanation:
The correct expressions that represent the total number of inches braided by robin and Olivia is,
⇒ 4 (1/3g - 3)
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
We have to given that;
Robin braided g inches of a friendship bracelet.
And, Olivia braided 12 less than 1/3 the number of inches robin braided.
Now, The total number of inches braided by Robin and Olivia = Number of inches braided by Robin + Number of inches braided by Olivia
Hence, We get;
⇒ g + 1/3g - 12
⇒ 4/3g - 12
⇒ 4 (1/3g - 3)
Thus, The correct expressions that represent the total number of inches braided by robin and Olivia is,
⇒ 4 (1/3g - 3)
