Using it's concept, it is found that the percent error for the amount of snowfall was of 51.85%.
The percent error of an amount is the absolute value of the difference between the actual amount and the expected amount, multiplied by 100% and divided by the expected amount.
In this problem:
Expected amount: 6.75 inches.Actual amount: 10.25 inches.Then, the percent error is:
[tex]P = \frac{|10.25 - 6.75|}{6.75} \times 100\% = 51.85\%[/tex]
The percent error was of 51.85%.

A line passes through (–7, –5) and (–5, 4).
a. Write an equation for the line in point-slope form.
b. Rewrite the equation in standard form using integers.
Answer:
b. y + 5 = 9/2 ( x + 7 ) ; - 9 x + 2 y = 53
Step-by-step explanation:
The equation:
y - y 1 = ( y2 - y1 ) / ( x2- x1) * ( x - x1 )
y - ( - 5 ) = ( 4 + 5 ) / ( - 5 + 7 ) * ( x - ( - 7 ) )
y + 5 = 9/2 ( x + 7 )
y + 5 = 9/2 x + 63 /2 / * 2
2 y + 10 = 9 x + 63
- 9 x + 2 x = 53
Answer:
C ) y + 5 = 9/2 ( x + 7 ) ; - 9 x + 2 y = 53
Answer:
Option C is correct
Step-by-step explanation:
Point slope form:
The equation of line is given by:
....[1] where m is the slope and a point lies on the line.
Given that:
A line passes through (-7,-5) and (-5,4).
Calculate slope:
Slope is given by:
Substitute the given values we have;
Simplify:
Substitute thee value of m and (-7, -5) in [1] we have;
Simplify:
⇒
Using distributive property :
Subtract 9x from both sides we have;
Subtract 10 from both sides we have;
Therefore, an equation for the line in point-slope form is and the equation in standard form using integers is

130/26 = 5Vera's piggy bank contained $10.90 in quarters, dimes, and nickels. There were six more than two times as
many nickels as quarters and four less than two times as many dimes as quarters.
Create an equation to represent the situation.
Answer:
[tex]6+2n+4-2d\cdot n = 1090[/tex]
Step-by-step explanation:
We have to convert everything to the same value. For example, 8$ would be 8 cents. And 1 Nickle would be 5 cents.
n = number of nickles
d = the number of dimes
q = number of quarters
1 nickle = 5 cents
1 dime = 10 cents
1 quarter = 25 cents
Step 1: Convert the total amount from dollars to cents.
There were $10.90 in total. Since there are 100 Cents in 1 Dollar, there would be 1090 cents in 10.90 dollars. (Tip you can easily find how many cents there are in dollars if you simply remove the decimal ".")
We are converting this because we need to have every value in the same term.
Step 2: Convert all of the amounts to cents.

take the -21 to the other side of the equation, when you do this it goes from a negative to a positive so we now have 63+21=12x
if we add 63 and 12 we get 84 decide by 12 because we have 12x and we get 7

please answer it correctly
Step-by-step explanation:
4.
GCF : greatest common factor, the biggest number all these numbers can be divided by without remainder.
so, 15, 30 and 45
let's find the basic factors of each
15/2 no
15/3 = 5
5/3 no
5/4 no
5/5 = 1
therefore, 3¹×5¹
30/2 = 15
15/3 = 5
5/3 no
5/4 no
5/5 = 1
therefore, 2¹×3¹×5¹
45/2 no
45/3 = 15
15/3 = 5
5/3 no
5/4 no
5/5 = 1
therefore, 3²×5¹
the largest combination of factors they all have is 3¹×5¹ = 15
so, the GCF = 15.
5.
since I don't know how many pupils there are this is a strange question.
or does this text mean there are 5 pupils ?
overall, there is something wrong with this question.
so, let's answer based on some assumptions :
the GCF (as in 4.) is 12
12×3 = 36
12×4 = 48
12×5 = 60
so, if there are 12 students, each one gets 5 notebooks, 4 ball pens and 3 correction tapes.
if there are 5 students, then each one gets 60/5 = 12 notebooks, 48/5 = 9 (3 remainder) ball pens and 36/5 = 7 (1 remainder) correction tapes.
6.
multiples of 4, that means 4*x with x = 1, 2, 3, 4, ...
so
4×1 = 4
4×2 = 8
4×3 = 12
4×4 = 16
therefore, B is the right answer.

question is in image, and answer choices are here:

Answer: x is equal to 4
Step-by-step explanation:
A triangle's angles sums up to 180°. So we already know that the three angles in this triangle add up to 180°. The equation would be as following.
(18x - 12) + 15x + (10x + 20) = 180
We first add like terms together.
43x + 8 = 180
We then substract 8 on both sides.
43x = 172
We finally divide 43 on both sides.
x = 4

a variable x has a normal distribution with mean 54 and standard deviation 5. approximately what percentage of the observations will fall between 44 and 64?
For a normal distribution with mean 54 and standard deviation 5 95.4% of them fall between 44 and 64
The z score is used to determine by how many standard deviations the raw score is above or below the mean. The z score is given by:
[tex]z=\frac{x-\mu}{\sigma} \\\\where\ \mu=mean.\sigma=standard\ deviation, x=raw\ score\\\\Given\ that\ mean(\mu)=54,standard \ deviation (\sigma)=5\\\\For\ x=44:\\\\z=\frac{44-54}{5}=-2\\\\For\ x=64:\\\\z=\frac{64-54}{5}=2[/tex]
Therefore., from the normal distribution table:
P(44<x<64) = P(-2< z < 2) = P(z < 2) - P(z < -2) = 0.9772 - 0.0228 = 0.9544
Hence, About 95.4% of them fall between 44 and 64.

Linear pair means a pair of adjacent angles formed when two lines intersect, and their sum is 180°
In the question it want one of the angles to be 16° more then the other, so the measures of the angles will be
180 - 16 = 164
164/2 = 82
Angle 1 = 82° Angle 2 = 82°+16 = 98°
Draw a straight angle (straight line), intersect it with another line such that the two angles that will be formed one of them will be of measure 98° and the other 82°

Most of the properties you listed are properties a function has, rather than what you would use to compare two functions.
