Answer:
Step-by-step explanation:
Given mean = 84,
Standard deviation = 2,
Sample 64,
95% confidence interval: z = 1.96
Applying empirical rule , means that 95% of data fall within two standard deviations.
ME = = 0.49
Rounding this to 0.5
CI = 83.5< mean < 84.5
Outside of this range= x ≤ 83.5 and ≥ 84.5
Answer:
15% off
Step-by-step explanation:
Answer:
153 degrees is the measure of the supplementary angle
These are exponents. To solve an exponent you need to multiply the base it self how many times its says in the power.
a²
a = base
<span>2 = power
</span>
7^5 = 7 × 7 × 7 × 7 × 7 = <span>16807
7^5 = </span><span>16807</span>
