\huge\text{Hey there!}

\mathsf{23n =2.4}

\large\text{DIVIDE 23 to BOTH SIDES}

\mathsf{\dfrac{23n}{23}=\dfrac{2.4}{23}}

\large\text{Cancel out: }\mathsf{\dfrac{23}{23}}\large\text{ because it gives you 1}

\large\text{Keep: }\mathsf{\dfrac{2.4}{23}}\large\text{ because it helps us solve for n}

\mathsf{n = \dfrac{2.4}{23}}

\mathsd{\dfrac{2.4}{23}= 2.4\div 23\rightarrow \bf 0.104348}

\boxed{\boxed{\large\textsf{Answer: \huge n = \bf 0.104348}}}\huge\checkmark

\boxed{\textsf{NONE OF THE ABOVE is your ANSWER}}

\text{Good luck on your assignment and enjoy your day!}

The loads carried by an elevator are found to follow a normal distribution with a mean weight of 1812 lbs, and a standard deviat
marta [7]

Answer:

No one of the mentioned

The interval is:

[ 1706.7 : 1917.3]  to find 95.5 % of all values

Step-by-step explanation:

We deal with a Normal Distribution, : μ = 1812 and σ = 105.3

We know  centered at mean value and at both sides at values σ/2 we will find 68.3 % of all values . In fact σ/2 to the left and σ/2 to the right means an interval μ + σ .

[μ + σ/2    :      μ  -  σ/2 ]      will lie 68.3 % of values

Following the same reasoning but now for a wider interval

[μ + σ   :    μ  -  σ ]  We will find 95.5 % of all values in our case that interval is:

1812 + 105,3  = 1917.3

1812 - 105,3   = 1706.7

[ 1706.7 : 1917.3] will be the interval to find 95.5 % of all values

Genie is making cookies and brownies. Each cookie uses 8 grams of flour and each brownie uses 12 grams of flour. She wants to ma
Nikolay [14]

The system of inequalities models correctly the number of cookies is c + b ≥ 125 and 8c + 12b ≤ 2000

Let c represent the number of cookies and let b represent the number of brownies.

Since Genie want to make more than 125 cookies and brownies altogether, hence this is given by:

c + b ≥ 125   (1)

Also, Genie has a total of 2,000 grams of flour, hence:

8c + 12b ≤ 2000  (2)

Therefore the system of inequalities models correctly the number of cookies is c + b ≥ 125 and 8c + 12b ≤ 2000
