1) first step
in first place you must to Know how many feets are in a mile, it is given at the exercise ( 5280 feet = 1 mile)
now Winston's wi-fi has a range of 1 1/2 miles, it is necessary to transform to mile, then 1 + 1/2 = 3/2
establish the following relation 1 mile ____ 5280 feet
3/2 mile _____ x feet
x = 3/2mile ×5280 feet/ 1 mile = 7920 miles this is the range of the Winston 's wi-fi
2 ) second step
in order to know the relation of proportion you must divide the largest amount between the lowest
7960/ 3920 = 2
3960/ 7960 = 1 / 2⇒ 2×3960 = 1×7960, it means that the signals have the relation of 1 : 2, then the value of the range of Winston's signal <em>is twice ( 2) </em>the value of the range of isaac's signal, therefore the value of ratio is 2
Answer:
x = 5
Step-by-step explanation:
Since the triangles have to be congruent (through SSS), we know that:
2x + 3 = 4x - 7
We simplify this to: 2x = 10
And then: x = 5
Answer:
-16
Step-by-step explanation:
-k² -(3k-5n)+4n k=-1 , n= -2
= -(-1)² - ( 3(-1) -5(-2) )+4(-2)
= -1-(-3+10)-8
= -1-(7)-8
= -1-7-8
= -16
Answer:
18
Step-by-step explanation:
(5/6)x – 4 = 11
(5/6)x = 11 + 4
(5/6)x = 15
5x = 15×6 = 90
x = 90/5 = 18
Which data set has a wider spread? Why? Set A: {9, 11, 24, 11, 4, 20, 16, 7, 18, 15, 28, 6} Set B: {9, 12, 15, 3, 21, 24, 5, 9,
olchik [2.2K]
Data Set A:
Lowest Value is 4
Highest Value is 28
Range = 28 - 4 = 24
Data Set B:
Lowest Value is 3
Highest Value is 24
Range = 24 - 3 = 21
Data Set A has bigger range than Data Set B, hence it has a wider range
Answer: Set A has a wider spread because its range is greater.
