For one month, Terry recorded the time at which her school bus arrived. She organized her results in a frequency table. Find the experimental probability that the bus will arrive between 8:20 and 8:24.
Answer:
Experimental Probability is found:
P = 11/24
Step-by-step explanation:
Experimental Probability can be defined as the ration of the number of times (frequency) a desirable event has occurred, to the Total number of time (total frequency) the activity has been performed.
Probability = P = Frequency of an event / Total Frequency
To find the total frequency, we add all three of the given frequencies:
Total Frequency = 10 + 11 + 3
Total Frequency = 24
Frequency of the event (times bus arrived between 8:20 to 8:24) = 11
So, experimental probabilty is found as:
P = 11/24
c) A shopkeeper made a loss of Rs 20 when he sold a bag at 20% discount. If he had sold it at 10% discount, he would have gained 8%. Find the marked price of the bag.
help!!
Answer: Marked price Rs. 600
Step-by-step explanation:
Let M be the marked price
1) When shop keeper sold at 20% discount, ie. SP = 0.8M
CP - SP = 20
CP = 20 + SP
CP = 20 + 0.8M
2) When shopkeeper sells at 8% discount, he makes a profit of 10%
SP = 0.9M/1.08
Equating 1 and 2, we get
20 + 0.8M = 0.9M/1.08
21.6 + 0.864M = 0.9M
0.036 M = 21.6
M = 21.6 / 0 036
M = 600

A shopkeeper made a loss of Rs 20 when he sold a bag at 20% discount. If he had sold it at 10% discount, he would have gained 8%. Find the marked price of the bag.
━━━━━━━━━━━━━━━━━━━━━━━━━
[tex]\Large\fbox{\color{purple}{ SOLUTION }}[/tex]
let M, S and C be the mark price, selling price & cost price respectively.
1) when shopkeeper sells at 20% discount then he suffers a loss of rupees 20 then we have :-
[tex]s = ( 1 - \frac{20}{100} ) \times m = 0.8m \\ \\ and \: c - s = 20[/tex]
C = 20 + 0.8 m ------------- eq 1
2) when shopkeeper sells at 20% discount then he makes a profit of 8% then we have
[tex]s = ( 1 - \frac{10}{100} ) \times m = 0.9m \\ \\ and \\ \\ s = ( 1 + \frac{8}{100} ) \times c = \: \frac{0.9m}{1.08} [/tex]
since the cost price of bag doesn't change and equating 1 and 2 we get
[tex]20 + 0.8m = \frac{0.9m}{1.08} \\ \\ 21.6 + 0.864m \: = 0.9m \\ \\ 0.036m \: = 21.6 \\ \\ m \: = 600[/tex]

PLEASE ANSWER ASAP! A copy machine reduces an original document using the ratio 5:3. What was the original length of a segment if, on the copy, it is 7.5 in. long? *Please provide an explanation!
Answer:
Divide the 7.5 by 3 to see how much bigger the ratio has to be.
7.5 / 3 = 2.5 so the ratio is 2.5 times bigger
multiply 5 by 2.5 to make the ratio equal and find the answer
5 x 2.5 = 12.5
It was 12.5 long and became 7.5 long

Answer:
230 - 151 + 180 + (43 - 12) = 290
Step-by-step explanation:
Use PEMDAS.
Evaluate the expression in the parentheses:
230 - 151 + 180 + (43 - 12)
43 - 12 = 31
230 - 151 + 180 + 31

)) Devon jarred 15 liters of jam after 3 days. How much jam did Devon jar if she spent 4 days
making jam? Assume the relationship is directly proportional.
Answer:
20 liters
Explanation:
To find out how much jam Devon would jar if she spent four days making jam, we must first find out how much jam she makes in one day. In order to do that, we must divide how many liters of jam she makes in three days by the amount of days it took her to make it (three days).
15 liters ÷ 3 days = 5 liters per day
So, Devon jars 5 liters of jam per day.
Now that we found out how much jam she makes in a day, let's find out how much jam she makes in four days. To do that, we must multiply the amount of jam she makes in a day by four days.
5 liters × 4 days = 20 liters
Therefore, Devon will jar 20 liters of jam if she spends four days making jam.

Answer:
Complementary angles are angles that add up to 90°. Supplementary angles add up to 180°.
Therefore, it's really easy to simply subtract the values that are less than 90 from 90 to receive the complement for those angles, but if it is above 90, subtract the number from 180. Therefore, your answers are as follows:
1. 54° and 144°
Complement: 90 - 36 = 54
Supplement: 180 - 36 = 144
2. 85° and 175°
Complement: 90 - 5 = 85
Supplement: 180 - 5 = 175
3. 20° and 110°
Complement: 90 - 70 = 20
Supplement: 180 - 70 = 110
4. 61° and 151°
Complement: 90 - 29 = 61
Supplement: 180 - 29 = 151
5. 40.8° and 130.8°
Complement: 90 - 49.2 = 40.8
Supplement: 180 - 49.2 = 130.8
6. 12°
Complement: 90 - 168 = -78 (negative angles do not work)
Supplement: 180 - 168 = 12
7. 79° and 169°
Complement: 90 - 11 = 79
Supplement: 180 - 11 = 169
8. 90 - 2x and 180 - 2x
Complement: 2x + (something) = 90 → 90 - 2x
Supplement: 180 - 2x

A survey showed that 79% of adults need correction (eyeglasses, contacts, surgery, etc.) for their eyesight. If 16 adults are randomly selected,
find the probability that no more than 1 of them need correction for their eyesight. Is 1 a significantly low number of adults requiring eyesight
correction?
The probability that no more than 1 of the 16 adults require eyesight correction is
(Round to three decimal places as needed.)
Answer:
P (X≤1) = 0.000
Step-by-step explanation:
Data given:
p = 79% = 0.79
q = 1 - 0.79 = 0.21
n = 16
P (no more than 1 in 16 adults) = P (X≤1)
P (X≤1) = P (X=0) + P (X=1)
We can find the probability by using binomial functions:
[tex]P=\frac{n!}{x!(n-x)!}p^x(1-p)^{n-x}[/tex]
P(X=0):P(X=0) = (16! / 0!(16-0)!) · 0.79⁰ · 0.21¹⁶
Use calculator to solve:
P(X=0) = 0.000000000798
P(X=1):P(X=1) = (16! / 1!(16-1)!) · 0.79¹ · 0.21¹⁵
Use calculator to solve:
P(X=1) = 0.000000034506
P(X≤1)P (X≤1) = P (X=0) + P (X=1)
P (X≤1) = 0.000000000798 + 0.000000034506
P (X≤1) = 0.00000003530
P (X≤1) = 0.000

A vial holds 2 milliliters of pixie dust. How many vials can we fill with 1 milliliters of pixie dust?
Answer:
1/2 a vial, or 0.5 a vial, or half a vial.
Step-by-step explanation:
A vial holds 2 millilitres. 1 millilitre is half of 2 millilitres.
You can fill 0.5 (or half) of a vial with 1 milliliter of pixie dust.
We have,
Dividing the amount of pixie dust (1 milliliter) by the capacity of each vial (2 milliliters) to determine how many vials can be filled.
Number of vials = Amount of pixie dust / Capacity of each vial
Number of vials = 1 milliliter / 2 milliliters
Number of vials = 0.5
Therefore,
You can fill 0.5 (or half) of a vial with 1 milliliter of pixie dust.

Answer:
Based on the given information in the problem, 18 is found to be 75% of 24.
Step-by-step explanation:
In order to solve this problem, we must first know what we are being asked to do. In the problem, we are asked to find what percent of 24 is 18. We can find this percentage by dividing. We will divide 24 by 18.
18 ÷ 24 = 0.75
Now, we multiply this number by 100 to get the percent.
0.75 × 100 = 75
So, 18 is 75% of 24.

the correct answer would be 75%
The measure of angle 3 is 42°
What is the measure of angle 1 in degrees
Answer:
48 degrees
Step-by-step explanation:
Angle 2 is a right angle.
Right angles are 90 degrees.
A line is 180 degrees.
Angle 1, 5, and 2 form a line.
180-90=90
That means that Angles 1 and 5 add up to 90 degrees.
We know that Angle 3 is 42 degrees.
Angle 3 and 5 are Vertical angles.
Vertical angles are always congruent.
This means that Angle 5 is also 42 degrees.
As we discussed earlier, Angles 1 and 5 are complementary. (Add up to 90 degrees)
42+x=90
Subtract 42 from both sides.
x=48
m<1=48

It is 48 degrees because I took the test

Step-by-step explanation:

9x + y = 28 ---------------(II)
9x - y = 26
9x = 26 + y
Substitute 9x = 26 + y in equation (II)
26 + y + y = 28 {add like terms}
26 + 2y = 28 {subtract 26 from both sides}
2y = 28 - 26
2y = 2 {divide both sides by 2}
y = 2/2
y = 1
