I had $3.00.
My Mom gave me $10.00.
My Dad Gave me $30.00.
My Aunt & Uncle gave me $100.00.
I had another $7.00.
How much did I have?
Right answer will get deleted.
I won against: I stole this post or sure the answer...
Answer:
We need to add to the $3.00 we have at the start, what they gave him:
He started with $3.00 and received $10.00:
3.00 + 10.00 = $13.00
Then (when having $13.00) received $30.00:
13.00 + 30.00 = $43.00
Then (when having $43.00) received $100.00:
43.00 + 100.00 = $143.00
Then (when having $143.00) he had another $7.00:
143.00 + 7.00 = $150.00
The answer is $150
I initially had $3
My mom gave me $10
= $10+$3
= $13
My dad gave me $30, my aunt and uncle also gave me $100
= $100+$13+$30
= $143
I had another $7
= $7 + $143
= $150
This makes it a total of $150
Hence the amount i have is $150

The ______ can be used to determine whether the graph a relation is a function.
Answer:
The vertical line test can be used to determine whether a graph represents a function. If we can draw any vertical line that intersects a graph more than once, then the graph does not define a function because a function has only one output value for each input value.

Rosalia passed out fliers that say, “Vote for Rosalia!” She gave out 85 fliers on Monday, 66 fliers on Tuesday, and 99 fliers on Wednesday. What fraction of the fliers did she give out on Wednesday? Use a diagonal fraction bar in your answer. Explain how you found the answer
Answer:
0.66
Step-by-step explanation:
Rosalia passed out fliers that say, “Vote for Rosalia!” She gave out 85 fliers on Monday, 66 fliers on Tuesday, and 99 fliers on Wednesday.
Total fliers shared= 85+66+99
Total fliers shared= 250 fliers
Fraction of the fliers she gave out on Wednesday= fliers on Wednesday/total fliers
=99/150
= 33/50
= 3.3/5
= 0.66

A child walks due east on the deck of a ship at 3 miles perhour.
The ship is moving north at a speed of 16 miles per hour.
Find the speed and direction of the child relative to thesurface of the water.
Speed = mph
The angle of the direction from the north = (radians)
Answer:
16.28 mph ; 79.38°
Step-by-step explanation:
Given the following :
Speed of child due east = 3mph
Speed of ship due North = 16mph
Relative speed of th child is obtained by using Pythagoras rule to find the hypotenus
Relative Speed = Sqrt(3² + 16²)
Relative Speed = sqrt(9 + 256)
= sqrt(265)
= 16.2788 mph
= 16.28 mph
From trigonometry ;
Tanθ = opposite / Adjacent
Tanθ = (16 / 3)
Tanθ = 5.333
θ = tan^-1(5.333)
θ = 79.379°
θ = 79.38°

Xbar= summation x/n= 40/4= 10
The sample standard deviation is:
S= √summation(x-xbar)²/ n-1
=√6/3= 1.4142
The degrees of freedom
df= N-1= 4-1= 3
For 95% confidence level, critical value of t
t= 3.182
The 95% confidence interval is:
=Xbar plus or minus t' *8/√n
= 10 plus or minus 3.182(1.4142/√4)
= 10plus or minus 2.25
So 7.75 or 12.25

In a poll of 555 randomly selected students, 40% stated that they enjoyed statisticsa. Identify the number of students who say that they enjoy statistics? Round to the nearest whole student if necessary.b. Construct a 95% confidence interval estimate of the percentage of all students who say that they enjoy statistics.c. Can we safely conclude that majority of students enjoy statistics? Explain.
Answer:
a
[tex]N = 222[/tex]
b
[tex]0.36< p <0.44[/tex]
c
No we can not safely conclude that majority of students enjoy statistics because the upper limit of the confidence level is less than 50%
Step-by-step explanation:
From the question we are told that
The sample size is [tex]n = 555[/tex]
The percentage that enjoyed statistics is [tex]\r p = 40% = 0.40[/tex]
Generally the number of student who say they enjoyed statistics is mathematically represented as
[tex]N = 0.40 * 55[/tex]
=> [tex]N = 222[/tex]
Given that the confidence level is 95% then the level of significance is mathematically represented as
[tex]\alpha = ( 100-95)\%[/tex]
=> [tex]\alpha = 0.05[/tex]
The critical value of [tex]\frac{\alpha }{2}[/tex] obtained from the normal distribution table is [tex]Z_{\frac{\alpha }{2} } = 1.96[/tex]
The margin of error is mathematically represented as
[tex]E = Z_{\frac{\alpha }{2} } * \sqrt{\frac{ \r p (1 - \r p )}{n} }[/tex]
=> [tex]E = 1.96 * \sqrt{ \frac{0.40 (1- 0.40 )}{ 555} }[/tex]
=>. [tex]E = 0.04[/tex]
The 95% confidence interval is mathematically represented as
[tex]\r p - E < p < \r p + E[/tex]
=> [tex]0.40 - 0.04 < p <0.40 + 0.04[/tex]
=> [tex]0.36< p <0.44[/tex]
No we can not safely conclude that majority of students enjoy statistics because the upper limit of the confidence level is less than 50%

Data was collected for 221 randomly selected 10 minute intervals. For each ten-minute interval, the number of people entering the atrium of a large mall were recorded. The data is summarized in the table below. Number of Guests Frequency 100 – 119 45 120 – 139 76 140 – 159 56 160 – 179 17 180 – 199 27 What is the class width for this GFDT?
Answer:
20
Step-by-step explanation:
From the above question, we were given the following information:
Number of Guests = Frequency
100 – 119 = 45
120 – 139 = 76
140 – 159 = 56
160 – 179 = 17
180 – 199 = 27
Class width can be defined as :
The difference between the upper limits of two consecutive classes, or the difference between the lower limits of two consecutive classes.
The class width for this GFDT : 139 - 119
= 20

Help me please thank you
Answer:
y = 120º
Step-by-step explanation:
180 - (33 + 87) = 60
x = 60
180 - 60 = 120
y = 120º
or y = 33 + 87, because the outer angle of one angle equals the other two inner angles.
Answer: 120°
Step-by-step explanation:
If you add up all the triangles angles, it always is 180. So, when you add 33+87, you get 120. This means that x=60 because 120+60 =180.
Then, you also know that x and y together, make a 180° also because it is a straight line. So, y is equal to 120° because 60+120 = 180°.
Hope this helps! :)

2. Find the solution to the following system of eguations using the addition method
4x - 5y = 13
X + 5y = -3
Answer: (2, -1)
Explanation: Since one equation has a -5y and the other equation
has a +5y, when we add the equations together, the y's will cancel out.
So we have 5x = 10 and x = 2.
To find y, plug 2 back in for x in either of the two original equations.
I have chosen to plug 2 into the second equation to get (2) + 5y = -3.
Solving from here, y = -1.
So our final answer is the ordered pair (2, -1).
Now, check your answer.

( -7v 4 - 5v ) - ( -5v 3 - 2v ) + ( -7v - 6v 4 - 4v 3 ) simplified
Answer:
-13v^4 + v^3 - 10v (if simplified)
Step-by-step explanation:
combine like terms
(-7v^4 - 5v) - (-5v^3 - 2v)+ ( - 7v - 6v^4 - 4v^3)
-7v^4 + -6v^4 = -13v^4
-5v^3 + -4v^3 = v^3 (the five becomes positive because of the negative sign infront of the parenthesis) Example: -(-5v^3) = +5v^3
-13v^4 + v^3 -5v -(-2v) -7v (now we have the -2 left alone in the parenthesis which means it becomes positive too) Example: -(-2v) = +2v
-5v +2v - 7v = -3v -7v = -10v
Answer: -13v^4 + v^3 - 10v
The grade received on a certain teacher's 100-point test varies in direct proportion to the amount of time a student spends preparing for the test. If a student receives 72 points on a test for which she spent 3 hours preparing, what score would she receive on the next test if she spent 4 hours preparing?
Answer:
The teacher woll award the student 96 points for studying for 4 hours
Step-by-step explanation:
The student receives 72 point for preparing a test as long as 3 hours.
If she prepares for another test for 4 hours.
3 hours= 72 points
4 hours=( 72*4)/3
4 hours=72/3 *4
4 hours = 24*4
4 hours= 96 points
The teacher woll award the student 96 points for studying for 4 hours
