Answer:
20% of 10% of 1000 = 20
Step-by-step explanation:
Now we have to,
→ find the 20% of 10% of 1000.
Let's find 10% of 1000,
→ (10/100) × 1000
→ 0.1 × 1000
→ 100
Then 20% of 10% of 1000 is,
→ (20/100) × 100
→ 0.2 × 100
→ 20
Hence, the answer is 20.
Which is the initial value that shrinks an exponential growth function by 50%? One-fifth One-fourth One-third One-half
Answer:
One-half
Step-by-step explanation:
Given
Exponential function
Required
The initial value that shrinks the function by [tex]50\%[/tex]
An exponential function is represented as:
[tex]y = ab^x[/tex]
Where the growth function is:
[tex]r = b^x[/tex]
[tex]a \to[/tex] initial value
For the growth function to shrink by x%, then:
[tex]a =1 - x\%[/tex]
In this case; x = 50. So, we have:
[tex]a =1 - 50\%[/tex]
Express as fraction
[tex]a =1 - \frac{50}{100}[/tex]
Take LCM
[tex]a =\frac{100 -50}{100}[/tex]
[tex]a =\frac{50}{100}[/tex]
Reduce fraction
[tex]a =\frac{1}{2}[/tex]

One angle of a rhombus measures 108°, and the shorter diagonal is 9 inches long. Approximately how long is the side of the rhombus?
Answer:
8 inches
Step-by-step explanation:
A rhombus is a four sides quadrilateral with the four sides equal in length
A rhombus has 4 equal sides and the diagonal bisect at right angles
Adjacent sides = 9/2 = 4.5
we are to determine the value of the hypotenuse given the adjacent side and angle (108/2) = 54
Cos 54 = adjacent / hypotenuse
0.58778 = 4.5 / hypotenuse
hypotenuse = 4.5 / 0.58778
=7.6559
= 8 inches

Step-by-step explanation:
Two high school basketball players each played 5 games. Their stats are summarized below:
Player A: Stats on 5 games → mean points scored = 25, standard deviation = 4
Player B: Scored 23, 27, 28, 22, 25 points on 5 consecutive games
Suppose a university basketball scout (a person who finds new players for a university's team) is deciding which player to recruit. Who should they choose? Justify your response. [3 marks]
HINT: Compare mean and variance of each player.
Answer:
Player B.
Step-by-step explanation:
Player A has a mean score of 25.
Let's calculate Player B's mean score and compare it to Player A's.
23 + 27 + 28 + 22 + 25 / 5 = 125 / 5 = 25.
So, Player A and Player B have the same mean score.
This doesn't tell the scout which player is "better", so let's look at the variance.
The other statistic given for Player A is the standard deviation for their points. The given number is 4. Let’s calculate the standard deviation for Player B, and compare it to player A.
Recall that we add up the squares of the difference between each score and the mean, divide it by the total number of data, and square root that. So, the standard deviation for player B is sqrt(2^2 + 2^2 + 3^2 + 3^2 + 0^2 / 5) = sqrt (26/5) = sqrt (5.2) = 2.3.
Excellent. We have player A’s standard deviation, as well as player B’s standard of deviation. Since player B’s standard deviation is less than player A’s, it can be inferred that player B has more consistent results than player A, and the scout should get Player B.
Hope this helps!

1. Explain a situation where you would expect to have a partial variation.
What makes this example a partial variation?
2. Explain a situation where you would expect to have a direct variation.
What makes this example a direct variation?
You can include a diagram/graph in your explanation if you wish.
Answer:
Here's the answers
Step-by-step explanation:
1. When two variables are in relation with a formula or a variable is related by the sum of two or more variables, then it is a partial variation. X = KY + C (where K and C are constants) is a straight line equation which is an example of partial variation.
2. The formula y=kxn y = k x n is used for direct variation. The value k is a nonzero constant greater than zero and is called the constant of variation.

solve the equation 3(17x-6.5)=108
a. x=-1.5
b. x=2
c. x=2.5
d. x=5.2
Answer:
C
Step-by-step explanation:
3(17x-6.5) =108
=17x-6.5=36
=17x =36 +6.5
= 17x=42.4
=x =2.5
Answer:
x= 2.5
Step-by-step explanation:
3(17x-6.5)=108
Divide each side by 3
3/3(17x-6.5)=108/3
17x - 6.5 = 36
Add 6.5 to each side
17x-6.5+6.5=36+6.5
17x = 42.5
Divide by 17
17x/17 = 42.5/17
x= 2.5

Find the length of x. Assume the triangles are similar.
A. 25
B. 12
C. 20
D. 19
Answer:
C=20
Step-by-step explanation:
The value of x is 20. so option C is correct.
What are corresponding sides?In literal sense, corresponding means pair wise sides. Like the right corner sides of two triangles etc.
For two similar figures, the pair by pair similar sides of those two similar figures are called corresponding sides. They are of same measurement.
Find the length of x. Let Assume the triangles are similar.
x/ 12 = 10/ 6
Cross multiplication;
x/ 12 = 10/ 6
x = 12 ( 10/ 6)
x = 20
Hence, the value of x is 20. so option C is correct.

Round 71.916476787 to 1 decimal place.
Answer:
71.9
Step-by-step explanation:
Whenever you want to round a number to a particular digit, look only at the digit immediately to its right. For example, if you want to round to the nearest tenth, look to the right of the tenths place: This would be the hundredths place digit. Then, if it is 5 or higher, you get to add one to the tenths digit.
After rounding 71.916476787 to 1 decimal place we get 71.9.
What is rounding of numbers ?We round numbers to get an approximate value of the given number in more compact form and which is easy to work with.
According to the given question we have to round 71.916476787 to 1 decimal place.
So, to round 71.916476787 to 1 decimal place we'll look at the digit of 2 decimal place here in this number it is 1 hence it is less than 5 so we can make all the digits after 1 decimal places zero and rewrite this number as
71.900000000 and we know zeroes are meaning less to the right of the decimal so this can be written as 71.9.
