Answer:
2 miles
Step-by-step explanation:
Given that :
Distance from home to store and back = 1/2 mile
In a week :
Number of times he walked from home to store and back = 1 time
Number of times she rode to store and back = 3 time
Note distance does not change whether she rode or walked:
Hence,
miles walked = 1/2 miles * 1 = 1/2 miles
Miles biked = 1/2 miles * 3 = 3/2 miles
Total Number of miles :
(1/2 + 3/2) = (1 + 3) /2 = 4/2 = 2 miles
POSSIBLE POINTS: 0.71 An MP3 player has 60 songs stored on it. Of the songs, 21 are rock, 9 are rap, 18 are dance, and 12 are country. If songs are played randomly, find the probability of each event. A rap song is played
Answer:
outcome for rock = 21/60 = 7/20
outcome for rap = 3/20
outcome for dance = 3/10 or 6/20
outcome for country 1/5, 2/10 or 4/20
Step-by-step explanation:
possible outcomes = 21+9+18+12 = 60
outcome for rock = 21/60 = 7/20
outcome for rap = 3/20
outcome for dance = 3/10 or 6/20
outcome for country 1/5, 2/10 or 4/20
The probability of playing a rap song is 3/20.
What is probability?Probability deals with the occurrence of a random event. The chance that a given event will occur. It is the measure of the likelihood of an event to occur.The value is expressed from zero to one.
For the given situation,
0.71 An MP3 player has 60 songs.
The sample space is the number of songs stored in MP3 player.
⇒ [tex]n(s)=60[/tex]
Number of rock songs, [tex]n(rock)=21[/tex]
Number of rap songs, [tex]n(rap)=9[/tex]
Number of dance songs, [tex]n(dance)=18[/tex]
Number of country songs, [tex]n(country)=12[/tex]
Formula for the probability of an event is [tex]P(e)=\frac{n(e)}{n(s)}[/tex]
Probability of playing a rock song, [tex]P(rock)=\frac{21}{60}[/tex]
⇒ [tex]\frac{7}{20}[/tex]
Probability of playing a rap song, [tex]P(rap)=\frac{9}{60}[/tex]
⇒ [tex]\frac{3}{20}[/tex]
Probability of playing a dance song, [tex]P(dance)=\frac{18}{60}[/tex]
⇒ [tex]\frac{9}{20}[/tex]
Probability of playing a country song, [tex]P(country)=\frac{12}{60}[/tex]
⇒ [tex]\frac{1}{5}[/tex]
Hence we can conclude that the probability of playing a rap song is 3/20.

what is .175 as a fraction
Answer:
175/1000
Step-by-step explanation:
The last number of .175 is in the thousandth place, therefore, the denominator must be 1000, and .175, is 175/1000 of 1000.
If you want to simplify it all the way it would be 7/40.

what is the all time low temperature in pennsylvania is this a statistical question
Answer:
The lowest temperature ever recorded in Pennsylvania, −42 °F (−41 °C), was at Smethport on January 5, 1904. Yes this is a statistical question.
Step-by-step explanation:
A statistical question is a question that can be answered by collecting data that vary. For example, “How old am I?” is not a statistical question, but “How old are the students in my school?” is a statistical question. So if you collect data from Pennsylvania's weather over the years you will find that the lowest temperature EVER RECORDED in Pennsylvania was −42 °F (−41 °C), at Smethport on January 5, 1904.

Your ship sinks and you swim to a nearby island. On this island, the inhabitants do not use money. The island residents use island fruit as money.
If 60 bananas = 20 coconuts
35 figs = 15 oranges
10 coconuts = 25 figs
200 figs = 1 boat
How many bananas would you need to purchase a boat to get off the island?
Answer:
240 bananas
Step-by-step explanation:
You would need 8 sets of figs. 10 coconuts is equal to 25 figs so you need 80 coconuts. You would need enough bananas to get 4 sets of coconuts. 60*4 = 240
Answer:
To buy the boat you would need 240 bananas.
Explanation:
3 bananas = 1 coconut
1 coconut = 2.5 figs
200 figs (price of boat) = 80 coconuts
80 coconuts (price of boat) = 240 bananas

Avery has two horses: Salt and Pepper. Every month, Salt eats 450 pounds of hay. Pepper is bigger, so he eats 550 pounds of hay each month. How many tons of hay do Salt and Pepper eat in a year?
Please help
Answer:
3.3 for pepper and 2.7 for salt which is 6 tons in total
Step-by-step explanation:
The number of tons of hay both Salt and Pepper eat in a year is 5.5 tons.
Given that, every month, Salt eats 450 pounds of hay. Pepper is bigger, so he eats 550 pounds of hay each month.
What is the unitary method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Number of pounds of hay eaten by Salt in a year
= 450 × 12
= 5400 pounds
Number of pounds of hay eaten by Pepper in a year
= 550 × 12
= 6600 pounds
Total pounds of hay eaten by both the horses = 5400+6600
= 11000 pounds
In tons = 11000/2000
= 5.5 tons
Therefore, the number of tons of hay both Salt and Pepper eat in a year is 5.5 tons.

school, she is late one third of the time. For
the next 15 days, what is the probability
that she will be late at most three days?
Answer:
20.92 %.
Step-by-step explanation:
Add the individual probability of 0, 1, 2, and 3 late days out of 15
P(0 days) = (2/3)15 Notice that I have made P the probability of NOT being late.
P(1 day) = 15(2/3)14(1/3)

Brook makes this conjecture: Because the angles are equal, the proportion of area of each sector relative to the area of the given circle is also equal.
Answer:
The Brooks conjecture is true as the proportion of the area of a sector to the area of a circle is only dependent on the angle.
Step-by-step explanation:
The area of a sector for a radius r and an angle θ is given as
[tex]\Delta Sector=\dfrac{1}{2}r^2\theta[/tex]
Whereas the area of a circle for a radius r is given as
[tex]\Delta Circle=\pi r^2[/tex]
Now the ratio is given as
[tex]\dfrac{\Delta Sector}{\Delta Circle}=\dfrac{\dfrac{1}{2}r^2\theta}{\pi r^2}[/tex]
Here as r is the radius of the circle and it is the same therefore the above ratio is simplified to
[tex]\dfrac{\Delta Sector}{\Delta Circle}=\dfrac{\theta}{2\pi }[/tex]
Here as π is constant the only variable here is θ. Thus according to Brooks conjecture when the angles are equal, the proportion of area of each sector relative to the area of the given circle is also equal is true.

A 20-foot ladder leans against a wall, making a 70° angle with the ground. To the nearest tenth of a foot, how far up the wall will the ladder reach? 6.8 6.9 I 3) 18.7 18.8
Answer:
4) 18.8
Step-by-step explanation:
What we are trying to find is the opposite of the triangle with the angle and the hypotenuse. The equation for that is sin(degrees) = opp/hyp
the degrees is 70, the opposite is x, and the hypotenuse is 20
sin(70) = x/20
0.93969262078 = x/20
18.7938524 = x
18.7938524 rounds to 18.8 so the answer is 4

Answer:
4
Step-by-step explanation:
The slope of L1 is given by the slope formula:
m = (y2 -y1)/(x2 -x1)
m = (5 -1)/(-2 -(-3)) = 4/1 = 4
The slope of L2 is the same as the slope of L1. The slope is 4.
