Answer:
A little less than 5.
Step-by-step explanation:
An estimate means you should be able to do it in your head.
400/80 = 5 So the answer should be about 5
Can we get it a little closer? Maybe.
Divide 375 in your head by 25. It's about 15
Divide 80 by 25 which is about 3.2
15/3.2 It's under 5. but not by much. Only now can you use a calculator. The rounded answer is 4.6
how large should my sample size be if i want to have a 95% level of confidence with a margin of error of at most 3%
Answer:
do 95 % times 3% or to 1% keep picking and subtract your answer thats how i would solve the problem but still this is middle school at most level math i mean use a calculator
give me brainiest
i told you how to solve it so at least your learning a littlie
and not direct cheating
do
.95 times .3 .229 . 228 .227 go down to i would say porbaly 1 to get your awnser
stop when u want
i would start
.95 times .015

The writing with me trying in pencil and the question is find the measure of each angle indicated
Answer:
Again every triangle is 180° and so is every straight line, so 180-105 is 75° so 75°+85° is 160 and 180-160 is 20° so your missing angle is 20°
your local park let's you swim in the community pool 8 times in one month. how many times will you be able to swim in the community pool for 3 years and 5 months
Answer:
136 times
Step-by-step explanation:
If the park lets you swim 8 times in one month, there are 12 months in one year, therefore you could swim eight times each of those twelve months. 8 x 12 = 96. Then, you have 5 more months left to swim. So, if you swam eight times each month that would be 8 x 5 = 40. So, 96 + 40 = 136.

State the domain and range then determine if the relation is a function
Answer: Number 7 is not a function. Also number 8 is not a function.
Step-by-step explanation:
Number 7s x and y values in the table do not increase or decrese at a constant rate so the table is not a function.
Number 8_ So the x input 6 has two y outputs so that makes it not a function. In other words an input or x value only has 1 and only 1 output to make it a function.
I hope this helps! I could only answer the question about the functions on numbers 7 and 8 not the Domain and range for those questions.
The equation of the line graph is y=__x+__
Answer:
Step-by-step explanation:
Formula is y= mx+b
b= slope intercept which is 3
m is the slope and it is 3/2 = 1.5
so...
y= __x+__
y= 1.5x+ 3
Hope this helped!
what is standard form of y=2/5x - 3?
Answer:
Bring 3x to the left: −3x + y = 2. Multiply all by −1: 3x − y = −2. Note: A = 3, B = −1, C = −2. This form: Ax + By + C = 0. is sometimes called "Standard Form", but is more properly called the "General Form".

The graphs of functions fand g are shown.
Function g is defined as g(x) = f(x) - C. What is the value of c?
The value of c?
Answer:
c = 3
Step-by-step explanation:
Function g is defined as,
g(x) = f(x) - c
Which states that the image function 'g' is formed by shifting function 'f' by c units down along y-axis.
Since, function 'f' has been shifted 3 units down to form the image function 'g'.
Therefore, value of c = 3 will be the answer.

A company that manufactures widgets has fixed cost of $9,186.00 each month and a cost of $2.75 for each widget it produces which of the following equations could be used to determine the total production cost for the company if it produced X what is last month let X represent the number of widgets the factory produce last month and Y represent the total production cost from the factory
Answer:
[tex]y = \$9186.00 + \$2.75x[/tex]
Step-by-step explanation:
Given
[tex]Fixed\ Cost = \$9186.00[/tex]
[tex]Cost\ per\ widget =\$2.75[/tex]
Required
Determine an expression for this scenario
x = number of widgets
y = total cost
The expression for y is calculated as follows:
[tex]y = Fixed\ Cost + Cost\ per\ widget * Number\ of\ widgets[/tex]
Substitute values for the fixed cost, the cost per widget and the number of widgets
[tex]y = \$9186.00 + \$2.75 * x[/tex]
[tex]y = \$9186.00 + \$2.75x[/tex]
A grocery store has 60% mark up on a can of soup. The can of soup cost the store $1.50 what is the selling price for the can of soup
Answer: $2.40
Work: So to find the markup price, you multiply the price by the markup, so the equation is going to be $1.50 x .60 (Remember, Markup and tax, you move the decimal two spots over) After the equation, you get $0.90. Add 90 cents to $1.50, and you get $2.40 (The Selling price with the markup) I hope this helps, and stay safe! :)
Answer:
The new selling price is $2.40
Step-by-step explanation:
1. First we need to convert 60% into a decimal, which is 0.60.
2. Now we need to multiply $1.50 and 0.60, so 1.50 × 0.60 = 0.90.
They added $0.90 to the can, now we need to add $1.50 and $0.90, which is $2.40.
Suppose the solutions of a homogeneous system of five linear equationsin six unknowns are all multiples of one nonzero solution. Will thesystem necessarily have a solution for every possible choice of constantson the right sides of the equations? Explain.
Step-by-step explanation:
The problem can be written as
Ar = where A = 5×6 matrix. dim(NullA)=1 as all the multiples of Ar=0
are the multiple of one non zero solution.
Since A is 5×6 , A n= 6
rank(A)= n-dim(Nul A)= n-1= 6-1=5
now, imagine A as 5 dimensional subspace of R^5( As A has 5 rows)
Therefore Col(A)= R^5
This means that Ar = b has a solution for every b.
