Many states assess the skills of their students in various grades. One of the tests provided by a national association assesses the reading skills of 12th-grade students. In a recent year, the national mean score was 286 and the standard deviation was 38. Assuming that these scores are approximately Normally distributed, N(286, 38), use the 68-95-99.7 rule to give a range of scores that includes 95% of these students.

Answers

Answer:

95% of these scores are between 210 and 362.

Step-by-step explanation:

The Empirical Rule states that, for a normally distributed random variable:

68% of the measures are within 1 standard deviation of the mean.

95% of the measures are within 2 standard deviation of the mean.

99.7% of the measures are within 3 standard deviations of the mean.

In this problem, we have that:

Mean = 286, Standard deviation = 38

Use the 68-95-99.7 rule to give a range of scores that includes 95% of these students.

This is within 2 standard deviations of the mean. So

286 - 2*38 = 286 - 76 = 210

286 + 2*38 = 286 + 76 = 362

95% of these scores are between 210 and 362.

Doug earns $10.50 per hour working at a restaurant. On friday he spent 1 3/24 hours cleaning, 2 1/3 hours doing paperwork, and 1 5/12 hours serving customers. What were doug's earnings?

Answers

Answer:

57.75

Step-by-step explanation:

Doug did clean 1 3/4 hour.

Doug did paperwork for 2 1/3 hour

Doug did serving for 1 5/12

Add 1 3/4+ 2 1/3+1 5/12=16/12 or 5.5 hrs

In one hour Doug earns  $ 10.50 .

Therefore in 5.5 hour Doug earns  5.5  $  10.50  = $ 57.75  

Hence the total which Doug earned is  $ 57.75

Answer:

B = 31°

a = 18.9

b = 11.3

Step-by-step explanation:

✔️B = 180° - (90° + 59°) (sum of triangle)

B = 31°

✔️Use trigonometric ratio to find a:

Reference angle = 59°

Side opposite to reference angle = a

Hypotenuse = 22

Thus,

Sin 59 = a/22

Multiply both sides by 22

22*sin 59 = a

18.9 = a

a = 18.9 (nearest tenth)

✔️Use trigonometric ratio to find a:

Reference angle = B = 31°

Side opposite to reference angle = b

Hypotenuse = 22

Thus,

Sin 31 = b/22

Multiply both sides by 22

22*sin 31 = b

11.3 = b

b = 11.3 (nearest tenth)

Which of the following is NOT a level of​ measurement? nominal ratio qualitative ordinal

Answers

Answer:

Nominal.

Step-by-step explanation:

The option that is NOT a level of measurement is qualitative.

With qualitative, numbers are not assigned to the measurement.

A level of measurement classifies and relates values to variables.  Four levels of measurement have been identified as nominal, ordinal, interval, and ratio.

Ordinal can be quantitative or qualitative, while interval and ratio are always quantitative, and nominal has non-quantitative values assigned as measurements.

Thus, qualitative is not a recognized level of measurement.

Step-by-step explanation:

The Interquartile range determines how consistence Annie and Ellen are. The greater the IQR, the less the consistency, while the lesser the IQR, the more consistency.

The IQR for Annie is lesser than that of Ellen because the rectangular box is smaller for Annie's than that of Ellen.

Therefore, Annie is more consistent.

Write the equation of the function of a parabola with vertex at (–1,–2) and a point (1,–6) that lies on the curve.

Question 9 options:

f(x) = −(x − 1)2 − 2


f(x) = −(x + 1)2 − 2


f(x) = (x + 1)2 – 2


f(x) = (x − 1)2 − 2

Answers

Answer:

The second answer is the correct one, f(x) = -(x + 1)² - 2

Step-by-step explanation:

We know that the answer must either be the second or third, because those two have (x + 1) squared, which means that the vertex must have an x co-ordinate of -1.

We also know that the third one can't be correct, as the y-coordinate of -6 requires a negative coefficient of the x^2.  Without that the parabola would be moving upward from its vertex of (-1, -2).

With those we can eliminate all answers but the second one
