Well 2.5 + 2.5 is 5 so 5 - 2.5 is 2.5
Answer:
2^6
Step-by-step explanation:
2*2*2*2*2*2
There are six 2's multiplied together so the base is 2 and the exponent is 6
2^6
Answer:
{h| 0 ≤ h ≤ 60}
Step-by-step explanation:
Next time, please separate the possible answer choices with commas or semi-colons, or put them on separate lines.
The second set says it all: {h| 0 ≤ h ≤ 60}. This guy cannot work more than 60 hours per week, and h cannot be negative.
Answer:
0.68
Step-by-step explanation:
The formula for z test is given above as:
z = p' - p/√(pq/n)
p' = sample proportion
= Number of infested samples(trees)/ Number of samples
p' = 127/1000 = 0.127
p = 12% = 0.12
q= 1 - 0.12 = 0.88
n = number of samples = 1000
z = 0.127 - 0.12/√(0.88 × 0.12/1000)
z = 0.007/√0.0001056
z = 0.007 /0.0102761861
z = 0.6811865737
Therefore, the z test statistic is approximately ≈ 0.68
