5x - y + z = -6
2x + 7y + 3z = 8
x + 2z = 6

Answers

Answer:

Step-by-step explanation:

The system of equations given are:

 

 5x - y + z = -6   ------------- i

 2x + 7y + 3z = 8  ---------- ii

  x + 2z = 6 ----------------- iii

Let us deal with equation i and ii first since they have 3 variables x, y and z;

      5x - y + z = -6                 x 7

       2x + 7y + 3z = 8            x 1

    35x  - 7y + 7z  = -42   ----  iv

      2x  + 7y + 3z  = 8       ---- v

Add equation iv and v;

    37x + 10z  = -34 ------vi

So, let us solve equation vi and iii:

               x + 2z = 6 - ---------- iii   x 10

               37x + 10z  = -34  --- iv  x 2

    10x + 20z   = 60         vi

     74x + 20z  = -68        vii

Subtract vi  - vii;

      -64x  = 128

          x  = -2

So;    put x  = -2 into iii;

           x + 2z  = 6

           -2 + 2z  = 6

            2z  = 6 + 2  = 8

           z  = 4

Put x  = -2 and z = 4 into equation i;

  5(-2) - y + 4  =  - 6

   -10 -y  +4  = -6

       -6  - y  = -6

             -y  = 0

              y  = 0

x + y = 30

y = 9x

Answers

Answer:

(3, 27)

Step-by-step explanation:

I will use substitution method.

y = 30-x

y = 9x

30 -x = 9x

30 = 10x

x = 3

So far we have (3, ?).

Now that we know x, we can plug in x to one of the equation to find y. I will plug it in at the bottom equation.

y = 9(3)

y = 27

Now we know that the solution is (3, 27).

x=3 y=27...I hope that helps!

An ice cream shop has a sign in their window that says, "We sell 12,000 scoops per month." The number of scoops has been rounded.
Which could be the number of scoops sold if they rounded to the nearest thousand

Answers

Answer:

around 11,000?

Step-by-step explanation:

The number of ice cream scoops sold from the shop if it is rounded to the nearest a thousand are 12,111 and 11,589.

What is the nearest thousand of a number?

To write the large number at the nearest round, we use the nearest thousand of the number. The rounded to the nearest thousand of a number makes the calculation easy, and the result to understand batter.

To round a number to nearest thousand, follow the steps below-

Step 1) Write down the number, which you have round to the nearest thousand.Step 2) Select the number which is at the thousand or at the 3rd place from right side of the number.Step 3) Look at the number which immediate right to this number. If this number is less than 5, then make all the digits right of it  1as zero.Step 4) Look at the number which immediate right to this number. If this number is more than 5, then replace all the digits right of it with zero by adding 1 into the thousand place digit.

An ice cream shop has a sign in their window that says, "We sell 12,000 scoops per month." The number of scoops has been rounded.

The options of this problem are-

A) 10,999B) 12,111C) 11,589

The number of scoops sold if they rounded to the nearest thousand. As the nearest number is 11,589 which is less than the 1200 which shows some of the ice cream has been sold.

Also the number 12,111 can be rounded to 12000.

Hence, the number of ice cream scoops sold from the shop if it is rounded to the nearest a thousand are 12,111 and 11,589.

Usually Holly leaves home to school at 9:00, however today she left home 20 minutes later. In order to be at school on time she increased her usual speed by 20% and still was at school 15 minutes later than usual. What is her usual time from home to school

Answers

Answer:

Her usual time from home to school is 30 minutes

Step-by-step explanation:

At any point in time;

distance = speed * time

Here, we want to calculate the normal time she spent going from home to school

Let the normal time be x minutes

And the normal speed be t m/min

Today, she increased her speed by 20%

Her speed today will be t + 20/100 * t =

1.2t m/min

Her distance from how to school normally is

xt meters

Now what this means is that, at the increased speed, she was able to get to school 5 minutes earlier

What we are saying is although, she lost 20 minutes initially, she was able to beat down the lateness by 5 minutes

So, the time spent on her increased speed journey is;

(x-5) minutes

At any point in time, the distance will be equal;

Thus, mathematically;

xt = 1.2t(x-5)

xt = 1.2xt - 6t

6t = 1.2xt-xt

6t = 0.2xt

t cancels out

0.2x = 6

x = 6/0.2

x = 30 minutes

Members at a popular fitness club currently pay a $40 per month membership fee. The owner of the club wants to raise the fee to $50 but is concerned that some members will leave the gym if the fee increases. To investigate, the owner plans to survey a random sample of the club members and construct a 95% confidence interval for the proportion of all members who would quit if the fee was raised to $50.

Answers

Answer:

(a) It implies that if many samples of the members of the fitness club were selected and many 95% confidence intervals were constructed, the true proportion of all members of the fitness club who would quit would be captured by about 95% of the intervals.

(b) It implies that there is a 95% confidence that the true proportion of all members of the fitness club who would quit if there is an increase in the fee will be captures by the interval 0.105 – 0.225 (i.e. calculated as 0.18 – 0.075 = 0.105 and 0.18 + 0.075 = 0.225).

(c.) No, as there are plausible values above 20 as it is not all the intervals that are below 20. The implication of this is that there is a possibility that more than 20% would quit.

(d) The implication of the condition is that the distribution of the sample is approximately normal. This gives the opportunity to do estimations. However, the it will not be possible to estimate the 2 critical values if the distribution is not approximately normal. .

Step-by-step explanation:

Note: This question is not complete. The complete question is therefore provided before answering the question as follows:

The owner of the club wants to raise the fee to $50 but is concerned that some members will leave the gym if the fee increases. To investigate, the owner plans to survey a random sample of the club members and construct a 95% confidence interval for the proportion of all members who would quit if the fee was raised to $50.

(a) Explain the meaning of "95% confidence" in the context of this study.

(b) After the owner conducted the survey, he calculated the confidence interval to be 0.18 +/- 0.075. Interpret this interval in the context of the study.

(c.) According to the club’s accountant, the fee increase will be worthwhile if fewer than 20% of the members quit. According to the interval from part (b) can the owner be confident that the fee increase will be worthwhile? Explain.

(d) One of the conditions for calculating the confidence interval in part (b) is that np ≥ 10 and n(1 – p) ≥ 10. Explain why it is necessary to check this condition.
