Answer:
500,000 + 7,000 + 20 + 1
Step-by-step explanation:
Answer:
The expanded form of 507,021 is 500,000 + 7,000 + 20 + 1.
Step-by-step explanation:
500,000 + 7,000 + 20 + 1
Explanation:
When writing numbers in expanded form, you are essentially breaking the number apart so that the value of every individual digit is shown.
Here are some examples of a number and its expanded form:
· 874,923 = 800,000 + 70,000 + 4,000 + 900 + 20 + 3
· 3,905 = 3,000 + 9,000 + 5
· 42,069 = 40,000 + 2,000 + 60 + 9
* note:
if the number you are going to write in expanded form includes a zero (ex: the number 42,069), you do not need to include the zero when writing each digits value. However, if you or your instructor prefers to include the value of zero, you may. To solve this problem, I will not be including the value of zero.
we understand what expanded form is, let's write 507,021 in expanded form.
Start by writing a list for the values of each individual digit:
· 500,000
· 7,000
· 20
· 1
Next, write the numbers so that they show they must be added.
500,000 + 7,000 + 20 + 1
A researcher varies the amount of caffeine given to three groups of participants (0, 100, and 200 mg) and then observes the anxiety level for each group. The most appropriate statistical test used to determine whether the groups differ is
Answer:
one way anova
Step-by-step explanation:
The answer to this question is the one way anova or the analysis of variance, the reason is because the One way anova statistical test is used to carry out comparisons between two groups or more in order to check if there is a statistically significant difference in their means. If the researcher wants to check if the groups differ, the one way anova test is the most appropriate test for him to use.
solve for x:
-x/3 = 2
Answer:
x = -6
Step-by-step explanation:
-x/3 = 2
Multiply each side by -3 to isolate x
-x/3 * -3= 2*-3
x = -6
Answer:
x= -6
Step-by-step explanation:
you want to issolate x.
Start by getting rid of that divison by inversing it. The inverse of division is multiplication, so we multiply 2 by 3 to get 6.
Now -x= 6
in order for it to be truely isolated, we must inverse the negative sign.
its x= -6

Has anyone answered this given is diameter and Tangent; find the missing exterior angle 20 points for each question?
Answer:
∠ABD = 56°
∠DEB = 56°
Step-by-step explanation:
∠ABE = 90 because of the tangent and radius are perpendicular
arc DE = 68° because ∠DBE = 34° (multiply by 2 to get arc)
Because EOB is a diameter the arc EDB is 180°
so 180-68=112°
arc DB = 112° Take half of that for angle DEB = 56°

1/2(x-6.5) = 3.16 what is x?
Answer:
x =12.82
Step-by-step explanation:
1/2(x-6.5) = 3.16
Multiply each side by 2
1/2(x-6.5) *2 = 3.16 *2
(x-6.5) = 6.32
Add 6.5 to each side
(x-6.5+6.5) = 6.32+ 6.5
x =12.82
Answer: 12.82
Step-by-step explanation:
1/2(x-6.5)= 3.16
x=12.82
Seven members of the track team run the mile. Their mile times are all faster than 7 minutes but not faster than 6 minutes. Can you conclude that there are two runners whose times are less than nine seconds apart
Answer:
There are at least two runners whose times are less than 9 seconds apart.
Step-by-step explanation:
Let's assume that Tₙ is the time of the n-th runner, we know that:
6 min < Tₙ < 7 min
knowing that:
1 min = 60 s
We can rewrite this as:
6*60 s < Tₙ < 7*60 s
360 s < Tₙ < 420 s
We know that there are 7 runners, and we want to see if we can conclude that there are two runners whose times are less than nine seconds.
So, the smallest time allowed in seconds is 361 seconds (the first value larger than 360 seg) while the largest time allowed is 419 seconds (the largest time allowed smallest than 420 seconds).
Now, let's assume that the first runner has the smallest time:
then:
T₁ = 361 s
Now let's add 9 seconds to the time of each runner (here we want to check that we can have all the runners with exactly 9 seconds apart in their times, so we will prove that the statement is false), then:
T₂ = 361s + 9s = 370s
T₃ = 370s + 9s = 379s
T₄ = 379s + 9s = 388s
T₄ = 388s + 9s = 397s
T₅ = 397s + 9s = 406s
T₆ = 406s + 9s = 415s
T₇ = 415s + 9s = 424s
But 424s > 420s
So this is not allowed (as the maximum time allowed was 419 s), so at least two of the runners must have times that are less than 9 seconds apart.
Then; Can you conclude that there are two runners whose times are less than nine seconds apart? Yes.
Yes conclude that there are two runners whose times are less than nine seconds apart.
Given that,
Number of members = 7
Their mile times are all faster than 7 minutes but not faster than 6 minutes.
We have to determine,
Can you conclude that there are two runners whose times are less than nine seconds apart.
According to the question,
Let's assume that Tₙ is the time of the nth runner,
Then,
[tex]6 min < T_n < 7 min\\\\And \ 1 min = 60 s\\\\6\times 60 s < T_n < 7\times 60 s\\\\360 \ sec < T_n < 420 \ sec[/tex]
There are 7 runners, conclude that there are two runners whose times are less than nine seconds.
So, The smallest time allowed in seconds is 361 seconds (the first value larger than 360 seconds).
While the largest time allowed is 419 seconds (the largest time allowed smallest than 420 seconds).
Therefore,
Let's assume that the first runner has the smallest time:
T₁ = 361 s
Adding 9 seconds to the time of each runner to check that all the runners with exactly 9 seconds apart in their times.
So, prove that the statement is false
Then:
[tex]T_2 = 361s + 9s = 370s\\\\T_3 = 370s + 9s = 379s\\\\T_4 = 379s + 9s = 388s\\\\T_5 = 388s + 9s = 397s\\\\T_6= 397s + 9s = 406s\\\\T_7 = 406s + 9s = 415s\\\\T_8 = 415s + 9s = 424s[/tex]
Here, [tex]424s>420s[/tex]
So, There is not allowed (as the maximum time allowed was 419 s), T least two of the runners must have times that are less than 9 seconds apart.
Therefore, Yes conclude that there are two runners whose times are less than nine seconds apart.

Answer:
Option 2
Step-by-step explanation:
Like terms are terms with the same variable and the same power.
Let's analysis and write the equation of each model to see if which of them has like terms:
Option 1:
We have x x => 2x
1 1 1 => 3
Equation of model=> 2x + 3
2x and 3 are unlike terms
Option 2:
We have x x => 2x
x x x => 3x
Equation of model=> 2x + 3x
2x and 3x are like terms
Option 3:
We have x x x => 3x
1 1 1 => 3
Equation of model=> 3x + 3 (contains unlike terms)
Option 4:
We have x => x
1 => 1
Equation of model=> x + 1 (unlike terms)

Answer:
Slope is -3
y-intercept is -3 and equation is y=-3x-3
Answer:
Slope: -3
y-intercept: -3
Equation: y = -3x - 3
Step-by-step explanation:
1. To get the slope (m):
m = rise / run = -3 / 1 --> it's negative 3 since the slope is going downwards
2. the y-intercept is the point that crosses the y-axis or when the x point is 0, so (0, -3)
3. Put is all together: y = -3x - 3
