Answer:
5 letters
Step-by-step explanation:
Let x = the number of letters engraved.
For the first store, the cost can be written as (18.50 + 0.15x).
For the second store, the cost can be written as (18 + 0.25x).
For the cost and value of x to be the same, let them equal eachother and evaluate x:
18.5 + 0.15x = 18 + 0.25
0.1x = 0.5
∴x=5

Answer:
100
Step-by-step explanation:
180-160 = 20
20+60=80
180-80= 100
it's opposite so the answer is 100
Answer:
the answer is 100° because a triangle is a total of
180° and a straight line is also 180° so 180-160=20
and 60+20=80
and 180 -80 = 100 and the angle your looking for is a opposite from the angle that you just found

Can you explain the notation T(0,16)?
Answer:
The decimal place accuracy of a number is the number of digits to the right of the decimal point. The decimal point is a period written between the digits of a number. If there is no decimal point, it is understood to be after the last digit on the right and there is no place (zero place) accuracy.
The significant digits of a number are those digits that are most accurate. If a number has no place accuracy and there is no string of zeroes ending the number on the right, all the digits are significant. If a number has no place accuracy and there is a string of zeroes ending the number on the right, the significant digits are those digits to the left of the string of zeroes. If a number has a decimal point, the significant digits are the digits starting from the first non-zero number on the left to the last digit written at the right end. In either case the number of significant digits is just the count of these digits.
Decimal notation is the regular written format for a number. Scientific notation of a number just writes the significant digits followed by an appropriate power of ten.
The most common form of scientific notation inserts a decimal point after the first significant digit, follows the significant digits with times, "x", and then 10 to a power. If the original number is at least one, the power is the number of digits between the decimal point and the first number on the left. If the number is less than one, the power is the negative of the number of digits to the right of the decimal point up to and including the first non-zero number.
Calculators and computer software sometimes write scientific notation with the significant digits followed by the letter "E" and then the power of 10, without writing the base. A decimal point is usually inserted after the first significant digit.

The standard deviation of the following data set is 0.31. 68% of the data would fall in which range?
4.3, 5.1, 3.9, 4.5, 4.4, 4.9, 5.0, 4.7, 4.1, 4.6, 4.4, 4.3, 4.8, 4.4, 4.2, 4.5, 4.4
Answer:
Pr(4.19 ≤ X ≤ 4.81)
Step-by-step explanation:
First of all, let's calculate the mean;
x¯ = (4.3 + 5.1 + 3.9 + 4.5 + 4.4 + 4.9 + 5.0 + 4.7 + 4.1 + 4.6 + 4.4 + 4.3 + 4.8 + 4.4 + 4.2 + 4.5 + 4.4)/17
x¯ = 76.5/17
x¯ = 4.5
We are given standard deviation; s = 0.31
Now, z-value for a 68% Confidence interval is 1
Range in which the data falls is;
Range = x¯ ± zs
Range = 4.5 ± (1 × 0.31)
Range is;
Pr[(4.5 - 0.31) ≤ X ≤ (4.5 + 0.31)]
Pr(4.19 ≤ X ≤ 4.81)
Answer:
Pr (3.57 ≤ X ≤ 5.43)

In a sale, a blow dryer is marked down from $18.98 to $11.39.
What is the percent decrease?
The percent decrease is 61.94%.
What is a percentage?A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.
Given:
In a sale,
a blow-dryer is marked down from $18.98 to $11.39.
Let n be the percent decrease.
So,
n = 11.39 x 100/18.39
n = 61.94
Therefore, the required percentage is 61.94%.

Find the slope and the y-intercept of the graph of the linear equation.
y+7=5/4x
The slope is
and the y-intercept is
Answer:
your slope would be 5/4
Step-by-step explanation:
your x will always be your slope. when you rewrite the equation it would be
y=5/4x-7
so from -7 you would go up 5 and over 4.
Again your x value will always be your slope.
