Jeremy is on the planning committee for the rock climbing club. He is putting together a trip where members
can go outdoor rock climbing. He is trying to determine how high the group should climb and how long the
trip should last. He calls multiple parks in the area that offer rock climbing and collects data on the height of
the rock formations and the average time it takes people to reach the top and come back down. The data he
found is shown.
Time to Climb (min)
Height (ft)

It gives me a list of numbers in a chart

Time to climb : 30 ,45 , 115 , 87, ,160,60,135,117,55,145,95,150,67,120,100,88,138,75,167,120

Height: 85,120,289,194,434,241,351,339,180,400,248,370,155,296,271,255,315,215,405,317

Explanation:

Draw a rectangle. Then draw three vertical lines inside to split the rectangle into 4 equal pieces. Shade one of the pieces to represent 1/4.

Now draw 2 horizontal lines to split that 1/4 piece into three equal smaller pieces. You should end up with a 3 by 4 grid of small squares.  There are 3*4 = 12 small squares total.

Each person gets 1/12 of a unit of ribbon, when we started off with 1/4 of a unit of ribbon. Notice how 3*(1/12) = 3/12 = 1/4.

Refer to the diagram below.

Answer:

[tex]\displaystyle \frac{1}{12}[/tex]

Step-by-step explanation:

Multiply both denominatour and numeratour by 3 to determine this:

[tex]\displaystyle \frac{3}{12} = \frac{1}{4}[1\:(or\:\frac{3}{3})] \\ \\ \boxed{\frac{1}{4}} = \frac{3}{12}[/tex]

Therefore, each person will obtain ¹⁄₁₂ of the ribbon.

Explanation:

The spreadsheet is shown below.

In cell B6, the formula used is the NORMINV function to get the z critical value. The name is the result of putting the words "NORM" and "INV" together, which refers to the inverse normal.

It's used to find the value of k in P(-k < Z < k) = 0.99, which in this case is roughly k = 2.576 so the z critical value is roughly z = 2.576

What you type in specifically is [tex]=\text{NORMINV}( (1-0.99)/2, 0, 1)[/tex]

The (1-0.99)/2 portion ensures that we get the alpha/2 value which in this case is 0.005

The 0,1 at the end refers to the mean and standard deviation respectively of the standard normal Z distribution.

The output of that NORMINV function is then made positive and then you'd round to 3 decimal places.

So that's how we can get excel to display z = 2.576

----------

The margin of error E formula is

E = z*sqrt(phat*(1-phat)/n)

which doesn't need an excel function to get the job done, though of course excel can handle it just fine. You'd type in the formula as shown, but be sure to reference the correct cells.

Once E is calculated, we compute the following

which are the lower (L) and upper (U) bounds of the confidence interval.

The results are L = 0.063 and U = 0.137

That confidence interval can be written in the form (0.063, 0.137) which is equivalent to saying 0.063 < p < 0.137

Answer:

Step-by-step explanation:

A system of equations can be written for the weights of the boxes based on the relationships given in the problem statement. One equation will be for the total weight of 1 large and 1 small box; the other will be for the total weight of 70 large and 60 small boxes.

Let L and S represent the weights of Large and Small boxes, respectively. The system of equations is ...

  L + S = 60 . . . . . . combined weight is 60 lbs

  70L +60S = 4000 . . . . weight of boxes in the truck

__

We can solve this by substituting for s in the second equation.

  70L +60(60 -L) = 4000

  10L = 400 . . . . . . . . . subtract 3600, simplify

  L = 40

  S = 60 -L = 20

A large box weighs 40 pounds; a small box weighs 20 pounds.

Answer:

407,102 meters

Step-by-step explanation:

Convert the kilometers to meters.

394 km x 1000 = 394000 meters

13 km x 1000 = 13000 meters

Add the results together.

407,000

Now add the remaining values to 407,000

407,000 + 34 = 407,034

407,034 + 68 = 407,102

The answer is 407,102 meters.

Answer:

1/3+1/8+2/6=19/24-5=1/24

From the given parameters, the fraction of time spent doing other things is 5/24

The given parameters are:

Sleep = 1/3

Homework = 1/8

Playing = 2/6

Doing other things = 5 hours

There are 24 hours in a day.

So, the fraction of time spent doing other things is the amount of time doing other things divided by the number of hours in a day

So, we have:

Time = 5/24

Hence, the fraction of time spent doing other things is 5/24

The potter probably doesn't want to apply the same glaze multiple times, in which case she has 15 choices for the first layer, 14 for the second, and 13 for the third, giving

15 * 14 * 13 = 2730

possible test vessels.

On the other hand, it's possible that the potter is fine with re-using the first glaze in the third layer. In that case, whichever glaze is used first is not counted among the options for the second layer, but it comes back for the third layer, so that there would be

15 * 14 * 14 = 2940

test vessels.

Answer:

13 to 10

Step-by-step explanation:

13 boys, 10 girls

13:10

The ratio of boys to girls in the classroom is  13:10

hence option B is correct

According too the given situation

The number of boys in the classroom = 13

The number of girls in the classroom = 10

Ratio is a quantitative relationship between two numbers showing a comparable form of magnitudes of both the numbers/quantities.

Let "a" and "b" be two numbers then the Ratio of "a" and "b" is shown as formulated in equation (1)

[tex]\rm r = a:b ........(1)[/tex]

The ratio of two numbers can be found out in simplest form by dividing these two numbers such that the division results in positive natural numbers for both the quantities.

So we can conclude that   the ratio of boys to girls in the classroom are

[tex]\rm \dfrac{Boys }{Girls } =\dfrac{13}{10} \\\\Boys : Girls = 13:10 \\[/tex]

So we can conclude that the ratio of boys to girls in the classroom is  13:10

hence option B is correct
