Jim drove 168 miles in 4hr. If he can keep the same pace, how long will it take him to drive 504 miles

Jobisdone [24]

Since he went 168 miles in 4 hours, then his speed is 42 mph. Then, 504 divided by 42 is 12. It will take 12 hours at a steady pace of 42 mph to reach 504 miles.

Answer:

a) (0.576, 0.624)

Step-by-step explanation:

Given that the sample proportion (p) = 60% = 0.6, sample size (n) = 900, confidence (C) = 85%

α = 1 - C = 1 - 0.85 = 0.15

α/2 = 0.075

The z score of α/2 (0.075) corresponds with the z score of 0.425 (0.5 - 0.075) which is equals to 1.44, hence $z_\frac{\alpha }{2} =1.44$

The margin of error (E) is:

$E=z_\frac{\alpha }{2} *\sqrt{\frac{p(1-p)}{n} } =1.44*\sqrt{\frac{0.6(1-0.6)}{900} } = 0.024$

The confidence interval = p ± E = 0.6 ± 0.024 = (0.576, 0.624)

Miguel made 80 on his Math test. He made 95 in last week's Math test.

We need to find the percent change on his scores. It can be calculated as follows :

$\%=\dfrac{\text{original score-initial score}}{\text{original socre}}}\times 100\\\\\%=\dfrac{95-80}{95}\times 100\\\\\%=15.78\%$

So, there is a percent change of 15.78%.
