Answer:
P is 250% of Q
Step-by-step explanation:
50/100 Q = 20/100P Multiply both sides by 100
50Q = 20 P Divide by 20
50/20 Q = P
2.5 Q = P
So P is 2.5 times the size of Q.
2.5 as a percent is 250 %
sfiso is not attending school on Saturday 1/3 of the day on sleep, 1/8 of his time on homework, 2/6 of the day playing and 5 hours doing other things. what fraction of the day does sfiso spend doing other things
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
How to determine the fraction of time?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

There are 13 boys and 10 girls in the classroom. What is the ratio of boys to girls?
A 10 to 13
B 13 to 10
C 23 to 13
D 23 to 10
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

Amanda has a piece of ribbon that is 1/4 had long. She wants to share the ribbon with 2 friends so that they can each wear a ribbon for breast cancer awareness month. If each of the 3 friends gets the same amount, how much ribbon will each person get?
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.

A delivery truck is transporting boxes of two sizes: large and small. The combined weight of a large box and a small box is 60 pounds. The truck is transporting 70 large boxes and 60 small boxes. If the truck is carrying a total of 4000 pounds in boxes, how much does each type of box weigh?
Answer:
large: 40 lbssmall: 20 lbsStep-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.

Suppose a potter has 15 choices of glazes to apply on her pottery. She knows that if she applies glaze A OVER glaze B, it may not look the same as applying glaze B OVER glaze A. She wants to test the effect of combining these glazes by dipping a small vessel into 3 of these glazes. She will dip deeply into the first glaze (to see how it looks alone), then less deep into the next glaze (to see how it looks when applied OVER the first glaze) and then barely dip into the third glaze (to see how it looks when applied OVER the previous two glazes).
Required:
How many possible test vessels can be glazed?
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.

If n = 440 and ^p(p-hat) = 0.1, construct a 99% confidence interval. Give your answers to three decimals. Please list formulas in excel used if possible
___ < p < ___
====================================================
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
L = phat - EU = phat + Ewhich 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
