Ava borrowed some money from her friend in order to help buy a new video game system. Ava agreed to pay back her friend $2 per w
nydimaria [60]

We know that Ava is paying $2 dollars per week so if L is the money that she owes and t is the number of weeks, and I is the initial debt so we can write an equation like:

L=I-2t

Now we can replace the info we have to find the value of I so:

10=I-2(5)

and we solve for I

\begin{gathered} I=10+10 \\ I=20 \end{gathered}

So the final equation will be:

L=20-2t

Two owners of a cattle ranch, Jo and Val, want to find the average weight for the ranch's 200 cows. Instead of weighing all of t
Zolol [24]

Answer:

The  value  is E =19.6

Step-by-step explanation:

From the question we are told that

  The mean of Jo  cows is  \= x_1 = 1350

  The standard deviation of Jo cow is  s_1 =  50

  The mean of Val  cows is \= x_2  = 1420

   The standard deviation of Val  cows  is  s_2 =  50

    The sample size for both Val  and  Jo  is  n = 25

Let assume that the level of significance is  \alpha = 0.05

Generally from the normal distribution table the critical value  of  \frac{\alpha }{2} is  

   Z_{\frac{\alpha }{2} } =  1.96

Generally the margin of error is mathematically represented as  

      E = Z_{\frac{\alpha }{2} } *  \frac{\sigma }{\sqrt{n} }

Hence margin of error for Jo is  

=>   E = 1.96 *  \frac{50}{\sqrt{25} }

=>   E =19.6

Jim was thinking of a number. Jim doubles it, then adds 19 to get an answer of 70.1. What was the original number?
Novosadov [1.4K]

Answer:

25.55

Step-by-step explanation:

Let us take the number he thinked of be x .

<u>On </u><u>doubling</u><u> </u><u>it </u><u>:</u><u>-</u><u> </u>

→ N = 2x

<u>On </u><u>adding</u><u> </u><u>1</u><u>9</u><u> </u><u>:</u><u>-</u><u> </u>

→ N = 2x + 19

<u>According</u><u> to</u><u> Question</u><u> </u><u>:</u><u>-</u><u> </u>

→ 2x + 19 = 70.1

→ 2x = 70.1 - 19

→ 2x = 51.1

→ x = 51.1/2

→ x = 25.55

<h3>Hence the required answer is 25.55</h3>
