Deciles are 61.3 and 67.7
What are deciles?
Deciles are measures of position calculated on a set of data. The deciles are the values that separate a distribution into ten equal parts, where each part contains the same number of observations). The decile is a member of the wider family of quantiles.
Given:
Normal distribution =64.5 inches
Standard deviation=σ =2.5 inches
So, here the z- score for left decile= -1.28
and for right decile= +1.28
we know,
z= x-[tex]\mu[/tex]/σ
x= zσ + [tex]\mu[/tex]
x=-1.28*2.5 + 64.5
x= 61.3 and,
x= 1.28*2.5 + 64.5
x=67.7
hence, the deciles are 61.3 and 67.7

If a lawnmower has a cost price of $2500 and was sold for $2895 what is the percentage profit
The profit percentage for the lawn owner is 15.8%
Profit Percentage:
Profit means, if the selling price of a product is more than its cost price, there is a profit earned in the transaction.
So, it can be calculated as,
Profit = Selling Price - Cost Price
The formulas for profit percentage is,
Profit percentage(P%) = (Profit /Cost Price) × 100
Given,
Here we need to find the profit percentage, If a lawnmower has a cost price of $2500 and was sold for $2895.
Based on the question,
We know that,
Cost Price = $2500
Selling Price = $2895
So, the profit is,
profit = $2895 - $2500
profit = $395
Now, the profit percentage is calculated by apply the values on the formula,
profit percentage (P%) = (395/2500) x 100
Therefore,
P% = 395/25
P% = 15.8%
Therefore, the profit percentage for the lawn owner is 15.8%.

9. If h(x)=√x-3 +5, then for what value(s) of 10
x does h(x) = 3?
Answer:
There are no values of x that make this equation true.
Step-by-step explanation:
We know h(x)=[tex]\sqrt{x-3} +5[/tex]
So lets substitute h(x) for 3
3=[tex]\sqrt{x-3}+5[/tex]
We are going to then subtract 5 from each side leaving us with
-2=[tex]\sqrt{x-3}[/tex]
We then need to get rid of the square root, so we will square both sides. which gives us
4=x-3
We then need to subtract 3 from both sides which leaves us with
x=1
However, when you substitute 1 for x into the original equation, you get
h(x)=[tex]\sqrt{-2}+5[/tex]
Which is not equal to 3
Therefore, there are no values of x that make this equation true.

It is given that Claire has $300 in an account and she decides that she is going to take out half of the amount left in there in the account at the end of each month.
For such a situation, first of all let's take a look at the graph given below;
Now, let us understand what is recursive and explicit;
Recursive: A recursive formula bases its value on the preceding term whereas,
Explicit: An explicit formula offers the value of a given phrase depending on the location.
Furthermore, by looking at the graph attached herewith, it can be figured out that,
Recursive formula for the above mentioned condition will be;
=> f(0) = 300, f(n)
=> f(n-1) . 1/2
and the Explicit formula for the above mentioned situation will be;
=> f(n) = 300 . (1/2)^x

Inequality:
Inequality means relation which makes a non-equal comparison between two numbers or other mathematical expressions.
Given,
A basketball team raised $200 to purchase new jerseys.
There are 8 people on the team and jerseys cost $22 each.
With the extra money, the team would like to purchase socks at $5 per pair.
Here we need to find the inequality that describes the situation and solve it. And also we need to find the greatest number of pairs of socks the team can purchase.
Let S be the number of Socks they brought.
Based on the given details,
The following inequality must be raised:
=> (22 x 8) + (5 x S) = 200
When we solve it,
=> 176 + 5S = 200
=> 5S = 200 - 176
=> 5S = 24
=> S = 24 / 5
Here the S has the value of 4 and the remaining is 4.
Therefore,
with the money left over, the team will be able to buy 4 pairs of socks, and there will be $ 4 left over.

What is coordinates of a point?The coordinates are a pair of numbers which characterize the exact location of a point on a cartesian plane through using horizontal and vertical lines.
The x and y values of a point on a graph are usually represented by (x, y). Each point or ordered pair has two coordinates.Now, as per the question.
To find the coordinates of U, use the midpoint formula with the coordinates of points u and v (Xv, Yv) and (Xm, Ym) respectively.
Let's refer to them as (Xu, Yu)
Midpoint formula {(Xv + Xu)/2, (Yv + Yu)/2)}
Fill in the recognized coordinates as needed.
Point V at (10, 7) = (Xv, Yv)
Midpoint, point M at (10, 6) = (Xm, Ym)
For the x coordinates;
(10 + Xu)/2 = 10
Xu = 10.
Similarly for the y coordinate;
(7 + Yu)/2 = 6
7 + Yu = 12
Yu = 5
We can test this by plugging U's coordinates into the midpoint formula.
