The mathematical statement of the expression t - 3 is the difference between t and 3
What are expressions?Expressions are mathematical statements that are represented by variables, coefficients and operators
How to determine the expression?The algebraic expression is given as
t - 3
The above mathematical representation is an algebraic expression that is already in its most simplified form
This means that the algebraic expression cannot be further simplified
However, the algebraic expression can be rewritten as a mathematical statement
Recall that, we have
t - 3
The pronunciation of the above expression is:
t minus 3
In expressions, minus represents difference
So, we have
t minus 3 can be represented as the difference between t and 3
Hence, the representation of the algebraic expression given as t - 3 is the difference between t and 3

What is a stem-and-leaf plot?A stem-and-leaf plot is a table that is used to display numerical data. A stem-and-leaf plot has two column, one for the stem and the other for the leaf. The stem is the first number in the digit while the leaf is the last number. For example in the number 59, 5 would be the stem and 9 would be the leaf.
Mode is the number that occurs most frequently in a dataset. The mode is 59 because it appears 6 times in the dataset.
Range is the difference between the highest number and the lowest number
Range = 59 - 9 = 50
Median is the number at the center of the dataset.
Median = (n + 1) / 2
37 / 2 = 18.5th term = (45 + 46) / 2 = 45.5
The interquartile range is the difference between the third quartile and the first quartile.
Third quartile = 3/4(n + 1)
3 / 4 x 37 = 27.75 term = 58
First quartile = 1/4 x (n + 1)
1/4 x 37 = 9.25term = (50 + 53) / 2 = 51.5

The side x of the rectangle is 36.0 cm
How to find side of a rectangle?A rectangle is a quadrilateral with opposite sides equal to each other and opposite sides parallel to each other.
All four angles of a rectangle are right angles.
The diagonal of a rectangle are equal in length to each other and they bisect each other at there point of intersection.
Therefore,
∠ COD = 48°
∠OCD = ∠ODC = 132 / 2 = 66°
Using sin law
OD / sin 66 = 16 / sin 48
OD sin 48 = 16 sin 66
OD = 16 sin 66 / sin 48
OD = 14.6167273223 / 0.74314482547
OD = 19.6687105931
OD = 19.7 cm
∠AOD = 180 - 48
∠AOD = 132°
∠OAD = ∠ODA = 48 / 2 = 24°
Hence, using sine law let's find x
19.7 / sin 24 = x / sin 132
x sin 24 = 19.7 sin 132
x = 19.7 sin 132 / sin 24
x = 14.6399530619 / 0.40673664307
x = 35.9935605802
Therefore,
x = 36.0 cm

3x + 4y = 25 is an example of a line that is parallel to the supplied line.
What is equation ?Equations are mathematical expressions that have two algebraic expression on either side of an equals (=) sign. The expressions on the left and right are shown to be equal to one another, demonstrating this relationship. L.H.S. = R.H.S. (left hand side = right hand side) is a fundamental mathematical formula. For an unknown quantity represented by an unknown variable, equations can be solved to determine its value. It is clear that a statement is not an equation if there is no "equal to" sign in it. The phrase will be regarded as an expression.
Given that : line that is parallel to the line 3x + 4y = 32 and contains
the point (7,1).
3x + 4y = 32 is the equation for given line
This type of line is called a slope intercept. The line has a slope of m=[tex]\frac{-3}{4}[/tex].
The slope of parallel lines is equal. As a result, all lines with slope m=[tex]\frac{-3}{4}[/tex].will be perpendicular to one another.

Large hospitals have more observations, therefore their results are less likely to deviate from 50% or have a wide range of results.

the population of a community is known to increase at a rate proportional to the number of people present at time t. if an initial population p0 has doubled in 9 years, how long will it take to triple?
Since the population increases at a rate proportional to the current number of people, the population will be three times of its initial population after 14.27 years.
The population of a community increases at a rate proportional to the number of people present at time t, means:
dP/dt = kP
where k is a constant.
Rearrange it:
(1/P) dP = k dt
Take the integral:
∫ (1/P) dP = ∫ k dt
ln P = kt + C, where C is a constant
Substitute t = 0, from the problem, it is known that P(t = 0) = P₀
Hence,
P(t) = P₀. e^(kt)
The population doubles after 9 years, means if we substitute t = 9
P(9) = P₀. e^(9k)
2P₀ = P₀. e^(9k)
2 = e^(9k)
Take the natural logarithmic:
ln 2 = 9k
k = (ln 2)/9 = 0.077
When the population grows to triple, it means P(t) = 3P₀
3P₀ = P₀. e^(kt)
ln 3 = kt
ln 3 = 0.077 t
t = (ln 3)/0.077 = 14.27 years.
Hence, the population will be three times of its initial population after 14.27 years.

A bottle of maple syrup in Wayne’s freezer needs to be warmed for breakfast. Sitting on the kitchen counter, the bottle temperature will go up a steady 9.6° C every hour. If the bottle temperature begins at the freezer temperature of –16° C, how many hours will it take to reach 20° C?
Change in temperature: (20 – (–16)) = 20 + 16 = 36
It will take the bottle of maple syrup 3 hours 45 minutes to reach 20° C from –16° C.
How to get the temperature changegiven data
the bottle temperature will go up a steady 9.6° C every hour
freezer temperature = –16° C
final temperature = 20° C
The temperature rise from –16° C to 20° C
from –16° C to 0° C = 16° C
from 0° C to 20° C = 20° C
adding both increments gives = 20 + 16 = 36° C
if every hour we have 9.6° C then how many hours will give 36° C
1 hour = 9.6° C
? hour = 36° C
we cross multiply to have
= 36 * 1 / 9.6
= 3.75
This is 3 hours then a fraction of some minutes, the fraction is gotten by
0.75 * 60 = 45
Therefore the time to reach 20° C is 3 hours 45 minutes

29,791 smaller squares
The number of smaller squares that can fit inside a larger square with a side length of 31 units is A. 961 smaller squares if the larger square is a plane.
What is a side length?A side length is one part of the length of an object.
Determining the number of smaller squares in a larger square depends on if the square is an enclosure or a plane.
If the square object is an enclosure, then it has three dimensions, length, width, and height, which are squared. In that case, the number of smaller squares will be 29,791.
But if the square object is a plane with two dimensions, the number of smaller squares is 961.
Side length = 31 units
Area of a square plane = 961 unit² (31 x 31)
Volume of a square enclosure = 29,791 unit³ (31 x 31 x 31)
Thus, the number of smaller squares depends on the dimensions of the larger square.
