Basically what you have to do is multiply the two numbers that are mentioned and that will be your answer.
This is because the item will have the same amount or length and you just need to find what it will be with multiple ones.
Next time you could highlight keywords that help you understand if you are supposed to multiply, divide, subtract, or add.
(0,6)(1,3)
slope(m) = (3 - 6) / (1 - 0) = -3
y - y1 = m(x - x1)
slope(m) = -3
(1,3)...x1 = 1 and y1 = 3
now we sub
y - 3 = -3(x - 1) <===
Answer:
x = 17
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides , that is
x² = 15² + 8² = 225 + 64 = 289 ( take square root of both sides )
x = 
= 17
Answer:
Hence the best estimate is population with correct option is 74% and
the value for x=148
Step-by-step explanation:
Given:
A sample of 200
Of which 148 prefer brand new coffee
To Find:
Which statement is true?
Solution:
n=200
x=148
remaining 52 prefer old ones .
So estimate population proportion,
p=x/n
p=148/200
p=0.74
p=74 %
Now, when x=52
p=x/n,
p=52/200
p=0.26
p=26%
There is no option for 52 and 24 %
Hence x=148 and p=74%.
Answer:
5.33
Step-by-step explanation:
2/3= 0.66
0.66 x 8 = 5.33
