Write 6.38 times 10 to the power of -5 as a ordinary number
Answer:
0.0000638
Step-by-step explanation:
all you need to do is move the decimal point over 5 times but this will only work if your multiply by 10 and that it has a negative exponent
The number 6.38×10⁻⁵ written in ordinary form is 1/638000.
What is scientific notation?In scientific notations numbers are written in the form of a base that is
0 ≤ b < 10 and multiplied by 10ⁿ where n represents integers.
We write large standard numbers in scientific form in a compact manner.
Given, A number in scientific form as 6.38×10⁻⁵.
Now, We know an exponent must be written as a positive value.
Therefore,
6.38×10⁻⁵.
= 1/ 6.38×10⁵.
Now, The ordinary form of the number is when we write without the exponent.
So,
1/ 6.38×10⁵ is,
= 1/638000.

Teams A and B are playing a series of games. The series is over as soon as a team
wins a total of three games. Team A is two times more likely to win a game than Team
B. A draw in a game is impossible. What is the probability that Team A wins the
series?
Answer:
79% - almost 4 times out of 5.
The key to this is realizing that the number of games will not always be 5.
If A wins in a sweep - you have 2/3*(2/3)*2/3 percent chance of that happening - 8/27, or 29.63%
If A wins in 4, now we have 2/3*(2/3)*2/3*(1/3)*3 - the 1/3 is the chance that B wins a game. Note - there are only 3 ways B can win a game, not 4. B cannot win Game 4 because Game 4 would not be played in case of a sweep. That is why you cannot use a straight Pascal’s triangle to get your coefficients - the 1–4–6–4–1 is not possible if B cannot win Game 4. Anyway, the math is the same as the above, a 29.63% chance of A winning in 4.
For a 5 game set, A could lose 2 games in 6 possible ways (lose 1&2, 1&3, 1&4, 2&3, 2&4 or 3&4). Again, A cannot lose Game 5 - it would not be played once A wins 3 games. So the odds become 2/3*(2/3)*2/3*(1/3)*(1/3)*6, or 19.75%.
Add them up and you get 79.01%

It is a linear pair of angles hence supplementary
[tex]\\ \tt\hookrightarrow 123+3x=180[/tex]
[tex]\\ \tt\hookrightarrow 3x=180-123[/tex]
[tex]\\ \tt\hookrightarrow 3x=57[/tex]
[tex]\\ \tt\hookrightarrow x=19[/tex]
Explanation:
The angles shown is supplementary because the sum of 123 and 3x is 180.
Thus, the equation formed:
123 + 3x = 180°Subtract 123 both sides:
123 + 3x = 180°=> 123 - 123 + 3x = 180 - 123=> 3x = 57Divide 3 both sides:
=> x = 57/3 = 19The value of x is 19.
Which of the following represents the measures of all angles coterminal with a 418° angle? 360 58n, for any whole number n 58 360n, for any integer n 58 360n, for any whole number n 360 58n, for any integer n.
Using the concept of the angle the conditions are solved. For any whole number n, 360+58n is coterminal with 418°. option C is correct.
What is an angle?Angle is the space between the line or the surface that meets. And the angle is measured in degree. For complete 1 rotation, the angle is 360 degrees.
Given

c. 58+360n, for any whole number n.
For any whole number n, 360+58n is coterminal with 418°.
d. 360 58n, for any integer n.
For any integer number n, 360+58n is not coterminal with 418° except one.
Thus, for any whole number n, 360+58n is coterminal with 418°. option C is correct.

Can someone help me please? Thank you.
Answer:
(2,2)
Step-by-step explanation:
x + 6y = 14
-3x + 5y = 4
x + 6y = 14
subtract 6y from both sides
x = 14 - 6y
-3(14 - 6y) + 5y = 4
-42 + 18y + 5y = 4
add 42 to both sides and simplify
23y = 46
y = 2
x = 14 - 6y
x = 14 - 6(2)
x = 14 - 12
x = 2

The following graph shows the amounts customers say they are willing to pay for jeans. What is the likelihood that a customer is willing to pay at least $95?
Considering that 30 out of 120 clients are willing to pay at least $95, we use the it's concept and find that there is a 0.25 = 25% probability that a customer is willing to pay at least $95.
What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes.
In this problem, we suppose that 30 out of 120 clients are willing to pay at least $95, hence:
[tex]p = \frac{30}{120} = 0.25[/tex]
There is a 0.25 = 25% probability that a customer is willing to pay at least $95.

Graph this line using the slope and y-intercept:
y=8x+2
Answer:
Two points, (0,2) & (1,10)
Step-by-step explanation:
We already know the first point (0,2) just by looking at the +2 in the problem
Now we use the system rise/run to solve the problem
Go up vertically 8 to get to 10 (this is the rise part)
Next, go over 1 to get your x-axis point (this is the run part)
So our next point is (1,10)
Hope this helps and please award brainliest if possible :)
Answer:
Step-by-step explanation:
Using the equation given:
8 is the gradient and 2 is the y-intercept
We can draw a point at (0,2) y-intercept
And we can substitute x with 1 to give us (1,10)

X+2 is a factor of x^3- kx^2 +3x+7k. Find the value of k.
Explanation:
If x+2 is a factor of the other polynomial mentioned, then x = -2 is a root of that polynomial.
This means plugging x = -2 into the cubic expression will have it result in zero.
x^3- kx^2 +3x+7k = y
(-2)^3- k*(-2)^2 +3*(-2)+7k = 0
-8 - 4k - 6 + 7k = 0
3k - 14 = 0
3k = 14
k = 14/3
What is the explicit formula for the sequence: 32, 48, 72, 108,..

formula
[tex]\\ \tt\hookrightarrow a_n=ar^{n-1}[/tex]
[tex]\\ \tt\hookrightarrow a_n=32(3/2)^{n-1}[/tex]
Answer:
[tex]a_n=32 \cdot \left(\dfrac32 \right)^{n-1}[/tex]
Step-by-step explanation:
The difference between each term in the sequence is not the same, therefore the sequence is a geometric sequence.
Geometric sequence formula: [tex]a_n=a r^{n-1}[/tex]
where [tex]a[/tex] is the start term and [tex]r[/tex] is the common ratio
Given [tex]a = 32[/tex]
To calculate [tex]r[/tex], divide one term by its previous term:
[tex]\implies r=\dfrac{a_4}{a_3}=\dfrac{108}{72}=\dfrac32[/tex]
Therefore, [tex]a_n=32 \cdot \left(\dfrac32 \right)^{n-1}[/tex]
Write an inequality that describes all the points that are more than 3 units from 5.
x>8 and x<2 are the two possible inequalities of |x - 5| > 3
What is Inequality?a relationship between two expressions or values that are not equal to each other is called 'inequality.
Let x be the number
|x - 5| > 3
Now solve for x.
Suppose x - 5 is positive. Then
x - 5 > 3
x > 8
Suppose x - 5 is negative. Then |x - 5| = -(x - 5) = 5 - x
5-x>3
5-3>x
2>x
x<2
Hence, x>8 and x<2 are the two possible inequalities of |x - 5| > 3
