This is an example of Cluster sampling.
Cluster sampling is a sampling method, where population is divided into clusters and then each sample from a selected cluster is sampled.
Yes this is also a random sample.
<span>y= 1.5x - 4
y= -x
replace </span>y= -x into y= 1.5x - 4
y= 1.5x - 4
-x = 1.5x - 4
1.5x +x = 4
2.5x = 4
x = 1.6
y= -x
y = -1.6
answer: (1.6, -1.6) is the solution
Answer:
Step-by-step explanation:
The x intercepts occur when the quadratic is equal to zero.
1.
x^2-7x-18=0 factoring we get
(x-9)(x+2)=0 since multiplying anything by zero is zero the x intercepts occur when
x=-2 and 9
2.
2b^2+17b+21=0
2b^2+14b+3b+21=0
2b(b+7)+3(b+7)=0
(2b+3)(b+7)=0
b=-7 and -1.5
Answer:
A. The digit 8 is in the place one million position
B. The digit 3 is in the place tens position
Step-by-step explanation:
Given:
98,045,132.706
9 is in the ten million position
8 is in the one million position
0 is in the hundred-thousand position
4 is in the ten-thousand position
5 is in the one-thousand position
1 is in the hundred position
3 is in the tens position
2 is in the one position
. Decimal
7 is in the tenth position
0 is in the hundredth position
6 is in the thousandth position
Therefore,
A. The digit 8 is in the place one million position
B. The digit 3 is in the place tens position
