Answer:
Mean of M = 0.794
Standard Error = 0.013875
Step-by-step explanation:
Given that :
Sample size, n = 64
Mean percentage accuracy, μ = 0.794
Standard deviation, σ = 0.1110
Since the distribution of scores is normal ;
Sample mean, m ~ μ
Hence, m ~ 0.794
The sample sta dard deviation of standard error ~ σ/sqrt(n)
Standard Error = 0.1110 / sqrt(64)
Standard Error = 0.1110 / 8
Standard Error = 0.013875
Actually it would be 4 hours $60 because the question says he earned the same amount of money at both jobs. The only place on the graph where both jobs earned the same amount for the same amount of time is where they intersect at 4 hours and 60$
<span>I believe that this would be an equation for this...y = 925 / z
Hope this helps!!

Answer: 87.5%
Step-by-step explanation:
From the question, we are informed that a rancher uses 1400 acres of his property for cattle grazing amd that the area of the property is 1600 acres. To get the percentage used for cattle grazing, we divide 1400 by 1600 and then multiply the result by 100%. Mathematically, this will be expressed as:
= 1400/1600 × 100
= 0.875 × 100%
= 87.5%
The percent that is used for cattle grazing is 87.5%.
