The line extends to the right, so the answer must be C or D. The dot is not filled in, which means -2 is not included in the solution. Therefore the correct answer is C: x is greater than -2.

Hope this helps.

I would go with C because if you do A then its all new students and thats one view D is the same. C seems like the best choice.

Jacob does the long jump for his track team. On his first jump, he jumped 7

USPshnik [31]

Answer: Jacob's second jump was 6 1/3 feet

Step-by-step explanation:

On his first jump, he jumped 7 2/3

feet. We would convert each mixed fraction to improper fraction

to enable easy addition and subtraction. Converting 7 2/3 feet to improper fraction, it becomes 23/3 feet.

His second jump was 1 1/3 feet shorter. Converting 1 1/3 feet to improper fraction, it becomes 4/3 feet.

Therefore, the distance that Jacob covered on his second jump would be

23/3 - 4/3 = 19/3 feet

Converting 19/3 feet back to mixed fraction, it becomes

6 1/3 feet

A simple random sample of 85 students is taken from a large university on the West Coast to estimate the proportion of students

ahrayia [7]

Answer:

95% confidence interval for p, the population proportion of students whose parents bought a car for them when they left for college

(0.4958 , 0.7041)

Step-by-step explanation:

Step(i):-

Given that the sample size 'n' = 85

The sample proportion

$p = \frac{x}{n} = \frac{51}{85} = 0.6$

95% confidence interval for p, the population proportion of students whose parents bought a car for them when they left for college

$(p^{-} -Z_{0.05} \sqrt{\frac{p(1-p)}{n} } , p^{-} +Z_{0.05} \sqrt{\frac{p(1-p)}{n} })$

Step(ii):-

Given that the level of significance

α = 0.05

Z₀.₀₅ = 1.96

$(0.6 -1.96 \sqrt{\frac{06(1-06)}{85} } , 0.6 +1.96 \sqrt{\frac{0.6(1-0.6)}{85} })$

(0.6 - 0.104138 , 0.6 +0.104138)

(0.4958 , 0.7041)

Final answer:-

95% confidence interval for p, the population proportion of students whose parents bought a car for them when they left for college

(0.4958 , 0.7041)
