A police officer claims that the proportion of drivers wearing a seat belt in a certain area is less than 40%. To test this claim, the officer collects a random sample of 80 drivers and monitors if the driver was wearing a seat belt. From this sample of 80 drivers, the police offers observes that 34 were wearing seat belts. Assume the conditions needed to conduct a one sample proportion test are satisfied. The setup for the null and alternative hypothesis is as follows: H0:p=0.40; Ha:p<0.40, which is a left-tailed test. The test statistic and p-value for this Hypothesis test are given as follows: z=0.456, p-value=0.676. Which of the following are appropriate conclusions for this hypothesis test? Select all that apply.

Answer:

∠a = 29° (alt. int. angles)

∠b = 46° (alt. int. angles)

∠1 = ∠a + ∠b

= 29° + 46°

= 75°

Answer:

Step-by-step explanation:

The general term of an arithmetic sequence is given by ...

  an = a1 +d(n -1) . . . . where a1 is the first term and d is the common difference

__

This formula can be used to find the value of d. The first term is given as 1, and the 5th term (a5) is given as 41. The value of n for the 5th term is 5.

  an = a1 +d(n -1)

  41 = 1 +d(5 -1) . . . . . substitute known values

  40 = 4d . . . . . . . subtract 1, simplify

  10 = d . . . . . . divide by 4

The common difference of this sequence is 10.

Answer:

G

Step-by-step explanation:

In the equation, 8.5 will represent how much money Oscar earns per hour, and the x represents how many hours he works. The inequality sign shows that the sum of 8.5x and 100 has to be at least 397.50 (397.50 and up), so H and J are automatically wrong. If Oscar had given his brother 100 dollars, there would be a subtraction sign, but there is an addition sign instead, meaning he gained 100 dollars that did not come from his job. It would be the most logical to say that his brother had given it to him, so G is the correct answer.

The total number of milk drank in a day since the significant figure is not specified is 0.325 L.

Significant figures are a way of approximation of large numbers to the required approximation such as two significant figures, three significant figures, or more, as the case may be.

From the given information:

The total number of milk drank in Liters in a day is:

= (0.125 + 0.20) L

= 0.325 L
