The object of a general chemistry experiment is to determine the amount (in milliliters) of sodium hydroxide (NaOH) solution nee

ded to neutralize 1 gram of a specified acid. This will be an exact amount, but when the experiment is run in the laboratory, variation will occur as the result of experimental error. Three titrations are made using phenolphthalein as an indicator of the neutrality of the solution (pH equals 7 for a neutral solution). The three volumes of NaOH required to attain a pH of 7 in each of the three titrations are as follows: 82.00, 75.65, and 75.43 milliliters.
Required:
Use a 99% confidence interval to estimate the mean number of milliliters required to neutralize 1 gram of the acid

I need help with this one <img src="https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B3%7D%20" id="TexFormula1" title=" \frac{1}{3} "
Vanyuwa [196]
To solve this questions, we can turn 2 into a fractions.

2 as a fraction is 2/1 (because 2 divide by 1 is still 2)
We can now use this to get our answer. 

1/3  ÷ 2/1 
=  1/3 × 1/2    (flip the fraction and then multiply)
= 1/6          (1 x 1 / 3 x 6)

Or 0.16666.. as a decimal

Y=x(x−2)^3 identify the zeros and their multiplicities.
lawyer [7]
  • The zeros of the function are 0 and 2
  • The multiplicity is the power to which the factors are raised. The multiplicities of the function are 1 and 3.

<h3>Zeros and multiplicities of functions</h3>

Given the function y=x(x-2)^3

The zeros of the function is at the point where y = 0

x(x-2)^3 =0\\x = 0\\(x-2)^3=0\\x-2=0\\x=2

Hence the zeros of the function are 0 and 2

The multiplicity is the power to which the factors are raised. The multiplicities of the function are 1 and 3.

Write the verbal sentence as an algebraic equation.
Dmitry_Shevchenko [17]

Step-by-step explanation:

product=× three=3 a number is unknown =x plus=+ five=5 is=equals to 20

3×x +5=20

3x+5=20

Subtract 5 from both sides

3x+5-5=20-5

3x=15

3x/3=15/3

x=5

Meg found one treasure at − 3 4 foot. Which of these location are higher than − 3 4 foot? Check all that apply. Negative StartFr
Neporo4naja [7]

Answer:

\frac{-1}{4}and \frac{-5}{8} are the locations higher than \frac{-3}{4} foot

Step-by-step explanation:

We are given that Meg found one treasure at \frac{-3}{4}foot

We are supposed to find Which of these location are higher than \frac{-3}{4}foot?

i) -\frac{7}{8}

So, this location is not  higher than \frac{-3}{4}foot

ii)-\frac{1}{4}

So, -\frac{1}{4}>\frac{-3}{4}

So, this location is higher than\frac{-3}{4} foot

iii) - 1 foot

-1 < \frac{-3}{4}

So,this location is not  higher than\frac{-3}{4}foot

iv)-2 feet

So,this location is not  higher than\frac{-3}{4}foot

v)\frac{-5}{8}

So, this location is higher than \frac{-3}{4}foot
