PLEASE HELP I'LL GIVE BRAINLIEST!!!!!!!!! According to the Census Bureau, in 2014 California had an estimated population of 3.88 × 107 and Wyoming had a population of 5.84 × 105. Complete the following sentences.
3.8216 × 107 0.38216 × 107 3.8216 × 106 38.216 × 107 0.66 × 101
66.4 × 101 6.64 × 101
The population of California is __________ more than the population of Wyoming
Alternatively, the population of California is _________ times the population of Wyoming.
Answer:
The population of California is [tex]3.3216 * 10^{7}[/tex] more than the population of Wyoming.
Alternatively, the population of California is [tex]6.64 * 10^{1}[/tex] times the population of Wyoming.
Step-by-step explanation:
The first part is to take the numbers out of the scientific notation. The estimated population of California is 38,800,000, and the population of Wyoming is 584,000.
Not that we've done that, let's start with the first part of the problem.
"The population of California is __________ more than the population of Wyoming."
This is a statement of subtraction, because it's not asking how many TIMES more. So, we subtract Wyoming's population from California's population.
[tex]38,800,000 - 584,000 = 38,216,000.[/tex]
Putting that number into scientific notation is easy: move the decimal to the place in the number where there will only be one number in front of the decimal: 3.3216. How many number slots until you have only one number in front of the decimal? 7. So, we know that the power of 10 is going to be 7. So, the first part of the question answers to:
[tex]3.8216 * 10^{7} .[/tex]
Now for the second part.
"Alternatively, the population of California is _________ times the population of Wyoming."
This is a problem of division. The question is asking us to divide California's population by Wyoming's population.
[tex]\frac{38,800,000}{584,000} = 0.664383562 * 10^{2} .[/tex]
We need to have one number in front of the decimal point, so we move it behind the first 6, giving us 6.64. Because we did this, we need to bump the exponent from 2 to 1, leaving us with:
[tex]6.64 * 10^{1}.[/tex]
So, the answer to the question is:
1. [tex]3.8216 * 10^{7}.[/tex]
2. [tex]6.64 * 10^{1}.[/tex]
Hope this helped you, and I hope you get a perfect score!! :)
Answer:
The population of California is ( 3.8216 x 10⁶ ) more than the population of Wyoming.
Alternatively, the population of California is ( 6.64 x 10¹ ) times the population of Wyoming.

Which of the following situations represent linear growth? Check all of the boxes that apply.
Martin’s savings account increases because he deposits $25 each week.
Cali’s pay increases by 3% per year.
Each week, an athlete getting into shape loses 2 pounds.
Mei-Lin earns $9 an hour at her job.
Answer:
A, C, and D.
Step-by-step explanation:
The situations that represent linear growth are:
a) Martin's savings account increases because he deposits $25 each week.
d) Mei-Lin earns $9 an hour at her job.
Given are conditions, we need to check which of them shows a linear growth,
Linear growth refers to a constant increase in a variable over time or with respect to another factor.
In both situations (a) and (d), the variables involved change at a constant rate.
In situation (a), Martin's savings account increases by $25 each week. This represents linear growth because the savings account balance is increasing by a fixed amount ($25) on a regular basis (each week).
In situation (d), Mei-Lin earns $9 an hour at her job. This also represents linear growth as the amount Mei-Lin earns increases at a fixed rate ($9) per unit of time (hour).
On the other hand, situations (b) and (c) do not represent linear growth:
In situation (b), Cali's pay increases by 3% per year. This represents exponential growth, not linear growth, because the percentage increase is applied to the current value each year, resulting in a compounding effect.
In situation (c), an athlete getting into shape loses 2 pounds each week. This represents a constant rate of change, but it is not linear growth because the weight loss is decreasing over time.
As the athlete loses weight, the rate of loss may decrease due to factors like metabolism or diminishing returns.
Hence the correct options are a) and d).

The value of 4/15 ÷ 2/3 is 2/5
In order to solve this, the first thing is to change the division sign to multiplication sign and this will be:
= 4/15 ÷ 2/3
= 4/15 × 3/2
= 12/30
Reduce to lowest term
12/30 = 2/5
In conclusion, the value of 4/15 ÷ 2/3 is 2/5.

find the polynomial function of degree 3 whose y intercepts is 2 and x is 2 and 3
Answer:
y = x³ - 3x² + 4x - 12
Step-by-step explanation:
We are told that the polynomial intercept is 3 degree and has it's intercepts at 2, 2 and 3.
Now, at y - intercept, y = 0m
Thus, the polynomial is;. (x - 2)(x - 2)(x - 3) = 0.
This gives;
(x² - 4x + 4)(x - 3) = 0
This gives;
x³ - 12x + 4x - 3x² + 12x - 12 = 0
x³ - 3x² + 4x - 12 = 0

Which brand should the store eliminate?
Answer:
Brand A
Step-by-step explanation:
Just took the quiz
The brand that should be Eliminated is Brand C.
The correct option is C.
Brand A :
Total Sold = 686
Returns = 33
so, % of returns = (33 * 100) / 686 = 4.8%
Brand B :
Total Sold = 492
Returns = 15
so, % of returns = (15 * 100) / 492 = 3.04%
Brand C :
Total Sold = 362
Returns = 29
so, % of returns = (29 * 100) / 362 = 8.01%
Brand D :-
Total Sold = 767
Returns = 32
so, % of returns = (32 * 100) / 767 = 4.17%
As we can see that, Brand C returns % is most.
Therefore, the store should eliminate Brand C.

Gary has 30 blueberry muffins which is 30%Of all blueberry muffins in her basket how many muffins are in her basket
Answer:
100
Step-by-step explanation:
If 30% of all of her muffins are blueberry muffins, that means that 30% of 100% are blueberry. We want to find how many total muffins there are in her basket. Using a ratio:
30 muffins 30%
----------------- = --------
x muffins 100%
Cross multiply:
30 (100) = 30 (x)
3000 = 30x
3000/30 = 30x/30
100 = x
x muffins = 100 muffins
So there are a total of 100 muffins in Gary's basket.

Assume you are planning a picnic for lunch, but when you woke up there were rain clouds in the sky. If 50% of rainy days start with rain clouds in the air, 20% of all days start with clouds in the air, and rain only typically occurs on 1 out of every 10 days, what is the probability that it will rain today and ruin your picnic
Answer:
0.25 = 25% probability that it will rain today and ruin your picnic
Step-by-step explanation:
Conditional Probability
We use the conditional probability formula to solve this question. It is
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]
In which
P(B|A) is the probability of event B happening, given that A happened.
[tex]P(A \cap B)[/tex] is the probability of both A and B happening.
P(A) is the probability of A happening.
In this question:
Event A: Cloudy skies
Event B: Rain
20% of all days start with clouds in the air
This means that [tex]P(A) = 0.2[/tex]
50% of rainy days start with rain clouds in the air
50% of 10%. So
[tex]P(A \cap B) = 0.5*0.1 = 0.05[/tex]
What is the probability that it will rain today and ruin your picnic
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.05}{0.2} = 0.25[/tex]
0.25 = 25% probability that it will rain today and ruin your picnic
How is the derivative of a function related to the slop of the function?
Hi there!
The derivative of the function is the slope of the function at a specific x-value, or its instantaneous rate of change.
For example, take the equation y = x².
Using the power rule, we get:
y' = 2x
If we plug in any x-value into this equation, we can find the slope of the function at any point.
Ex:
x = 0; 2(0) = slope of 0
x = 2; 2(2) = slope of 4
