Answer:
Lets say test tubes = t, and beakers = b
1 pack of (t) is $4 less than 1 pack of (b)
Since i have no prior information we are going to use variables for this equation:
1t (1 pack of test tubes) is $4 less than 1b (1 set of beakers)
so to quantify the equation, we have 8t and 12b.
if b is a number that IS quantifiable such as $5 we can easily figure out this answer.
Lets use and example that 1 set of beakers is $8, if we multiply $8 by 12 (the number of sets of beakers), we get: 96
Using the same example, if 1t is $4 less than 1b than 1t = $4. So, if we multiply $4 by 8 (the amount of packs of test tubes), we get: 32
If you take both of those numbers: 96, and 32 and you divide them you get 3. so that means that 1t = 3b
Answer = 1t = 3b
This may not be correct due to the little information that i got however i hope that, that works out for you :)
Answer:
The probability is 
Step-by-step explanation:
From the question we are told that
The sample size is n = 175
The population proportion is p = 0.45
Generally the mean of the sampling distribution is 
Generally the standard deviation is mathematically represented as
=> 
=> 
Generally the probability of that the sample proportion of orange candies will be between 0.35 and 0.55 is
=> 
Generally 
So
=> 
From the z-table
and
So
=>

precentage?
Step-by-step explanation:
Answer:
1). Simplifying
-4x + y = 6
Solving
-4x + y = 6
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-1y' to each side of the equation.
-4x + y + -1y = 6 + -1y
Combine like terms: y + -1y = 0
-4x + 0 = 6 + -1y
-4x = 6 + -1y
Divide each side by '-4'.
x = -1.5 + 0.25y
Simplifying
x = -1.5 + 0.25y

2). Simplifying
-5x + -1y = 21
Solving
-5x + -1y = 21
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add 'y' to each side of the equation.
-5x + -1y + y = 21 + y
Combine like terms: -1y + y = 0
-5x + 0 = 21 + y
-5x = 21 + y
Divide each side by '-5'.
x = -4.2 + -0.2y
Simplifying
x = -4.2 + -0.2y
