Answer:
400
Step-by-step explanation:
6/8 = 0.75 or 75% expected to respond favorably.
Margin of error 2.5%:
Lower bound: 0.75 - .025 = 0.725
Upper bound: 0.75 + .025 = 0.775
Range:
Lower bound: 8000 * 0.725 = 5800
Upper bound: 8000 * 0.775 = 6200
6200 - 5800 = 400
Answer: 5
The Distance between the coordinates of two points is measured by distance formula.
Step-by-step explanation:
The Distance between the coordinates of two points P(x1,y1) and Q(x2,y2) is measured by
Distance PQ=
(x2-x1)²+(y2-y1)²
So, the distance between (-1,4 ) and (2,0) can be calculated by
Distance=
(2-(-1))²+(0-4)²
=
(3)²+(-4)²
=
9+16 =
25 as
25 = 5
Distance = 5
So the distance between the two coordinates is 5.
Answer:
28.3 units (3 s.f.)
Step-by-step explanation:

Using the formula above,
distance
![= \sqrt{[6 - ( - 22)]^{2} + (16 - 12) {}^{2} }](https://tex.z-dn.net/?f=%20%3D%20%20%5Csqrt%7B%5B6%20-%20%28%20-%2022%29%5D%5E%7B2%7D%20%20%2B%20%2816%20-%2012%29%20%7B%7D%5E%7B2%7D%20%7D%20)




= 28.3 units (3s.f.)
There are ten tens in 100. 10x10=100. The answer is 10.
