Yours: mean: 17; median: 17; mode: none
Friends: mean: 16.4; median: 17; mode: 20
You have the higher mean.
Step-by-step explanation:
a.
Your mean:
(18 + 16 + 19 + 15 + 17) / 5
= 17
Your median:
15 , 16, 17, 18, 19
= 17
Your mode:
15 , 16, 17, 18, 19
= No mode (no number comes up repeatly)
Your friend's mean:
(20 + 20 + 13 + 12 + 17) / 5
= 16.4
Your friend's median:
12, 13, 17, 20, 20
= 17
Your friend's mode:
12, 13, 17, 20, 20
= 20

Transcribed Image Text:to the Tledrest tentn. A landscaper wants to place a stone walkway from one corner of the rectangular lawn to the opposite corner. The lawn is 23ft by 18ft. a.) What is the length of the walkway to the nearest foot? b.) If the stones cover one foot each how many stone will he have to buy to make sure the path is covered?
Answers
The length of the walkway is 24 ft, and you will need 24 stones to cover it.
What is the length of the walkway?
The length of the walkway will be equivalent to the hypotenuse of a right triangle with cathetus of 23ft and 18ft, so we can use the Pythagorean theorem to get it:
L^2 =(23fy)^2 + (18ft)^2
L = √( (23fy)^2 + (18ft)^2 ) = 23.77ft
The walkway is 23.77 ft long.
Rounding to the nearest foot, the length is 24 ft.
b) If each stone covers 1 ft, then you will need 24 stones.

Anuar has a collection of 80 toy vehicles. 3/5 of his toy vehicles are cars. The rest are motorcycles and buses. The number of motorcycles is 3 times the number of buses. How many toy motorcycles does Anuar have?
Answers
Answer:
He has 24 motorcycles
Step-by-step explanation:
I hope I could help!
Answer:
36 motorcycles
Step-by-step explanation:
calculate [tex]\frac{3}{5}[/tex] of 80
= [tex]\frac{3}{5}[/tex] × 80 ( cancel 5 and 80 by 5 )
= 3 × 16 = 48
there are 48 motorcycles and buses
let x be the number of buses then 3x is the number of motorcycles , then
x + 3x = 48
4x = 48 ( divide both sides by 4 )
x = 12
number of motorcycles = 3x = 3 × 12 = 36

A car travels at a speed of 65 miles per hour. How far will it travel in 5 hours?
Answers
Answer: Distance = 325 miles
Step-by-step explanation:
Distance = speed*time
We can plug in the values given for time and speed:
Distance = 65 miles/h * 5 hours
Distance = 325 miles
Answer:
325 miles
Step-by-step explanation:
To find out how far the car will travel in 5 hours, we first need to know how far it will travel in one hour.
Well, we are given that information.
Since we know that the car travels 65 miles in 1 hour, we just have to multiply 65 by the number of hours it will drive, which is 5 in this case.
5 x 65 = 325
The car will drive 325 miles in 5 hours.
Which of the following numbers can be expressed as repeating decimals? 4/7, 2/5, 7/8, 4/9
Answers
Answer:
4/7 & 4/9
Step-by-step explanation:
4/7 <-------- repeating decimal/rational4/9 <-------- repeating decimal/rationalNumbers with a repeating pattern of decimals are rational because when you put them into fractional form, both the numerator a and denominator b become non-fractional whole numbers. ------------------------------- 4/9A repeating decimal is a decimal number that goes on forever. We want to know if the decimal number you get when you divide the fraction 4/9 (4 ÷ 9) is repeating or non-repeating.Here are the steps to determine if 4/9 is a repeating decimal number:1) Find the denominator of 4/9 in its lowest form.The greatest common factor (GCF) of 4 and 9 is 1. Convert 4/9 to its simplest form by dividing the numerator and denominator by its GCF:4 ÷ 1/ 9 ÷ 1 = 4/9Thus, the denominator of 4/9 in its lowest form is 9.2) Find the prime factors of the answer in Step 1.The prime factors of 9 are all the prime numbers that you multiply together to get 9. The prime factors of 9 are:3 x 33) Determine if 4/9 is repeatingA fraction is a repeating decimal if the prime factors of the denominator of the fraction in its lowest form do not only contain 2s and/or 5s or do not have any prime factors at all. This is the case here, which means that our answer is as follows:4/9= repeating------------------------------------------ 4/7A repeating decimal is a decimal number that goes on forever. We want to know if the decimal number you get when you divide the fraction 4/7 (4 ÷ 7) is repeating or non-repeating.Here are the steps to determine if 4/7 is a repeating decimal number:1) Find the denominator of 4/7 in its lowest form.The greatest common factor (GCF) of 4 and 7 is 1. Convert 4/7 to its simplest form by dividing the numerator and denominator by its GCF:4÷1/7÷1=4/7Thus, the denominator of 4/7 in its lowest form is 7.2) Find the prime factors of the answer in Step 1.The prime factors of 7 are all the prime numbers that you multiply together to get 7. The prime factors of 7 are:73) Determine if 4/7 is repeatingA fraction is a repeating decimal if the prime factors of the denominator of the fraction in its lowest form do not only contain 2s and/or 5s or do not have any prime factors at all. This is the case here, which means that our answer is as follows:4/7= repeatingTherefore, the fraction 4/7 and 4/9 can be represented as repeating decimals.Last week, Kip went to the fair.
