A 3x with an exponet of 3
Answer:
(351.04, 368.96)
Step-by-step explanation:
Given that population mean= 360
Std devitaion = 4
margin of error = 2.5%= 0.025
Since population std deviation is known we can use Z critical value
For two tailed critical value for 2.5% would be
2.24
Margin of error = ±Critical value*std deviation
= ±2.24(4)
= ±8.96
Confidence interval =(Mean - margin of error, mean + margin of error)
=
////// The answer is: 4x+2
Answer: (a) 2³ ˣ 3 ˣ 5², 2 ˣ 3 ˣ 5² = 150
Step-by-step explanation:
This is problems on common factors.
(a) 600 = 2 × 2 × 2 × 3 × 5 × 5
= 2³ˣ 3 ˣ 5²
(b) The highest common factors could be calculated using factors methods and the divisional methods.
Here we go.
(i) 600 = 2³ ˣ 3 ˣ 5²
1050 = 2 ˣ 3 ˣ 5² ˣ 7, the highest common factor HCF will be
HCT = 2 ˣ 3 ˣ 5²
= 150.
The divisional methods.
600) 1050 ( 1
- 600
------
450 ) 600 ( 1
- 450
------
150 ) 450 ( 3
- 450
------
000
So the answer is 150, the principle is that you continue to divide and subtract until you arrive at zero.
Answer = 150
