If you want to find out how Addision paid each month, you have to have 36, then divide 36 by 12, and the answer will give you 3. So Addison paid $3 every month.

Hope this Helped

9. How many times did the temperature rise one degree per hour?

Zinaida [17]

A - none

This is because the closest it gets to one degree per hour is not rising, rather, it lowers one degree from three to four.

In "The Rainy Day," Longfellow uses additional unique strategies to create structure in his poem. Which one does NOT contribute

victus00 [196]

Answer:

Longfellow utilizes sentence length to create effect in the poem. He also uses repetition of phrase such as, " day is dark and dreary". The theme is also set by the ominous tone of the lyric. However, the utilization of Punctuation as a literary device is missing in the poem.

Therefore, it can be stated that Punctuation is not used in this creation by Longfellow. It is in simple and straightforward language with multiple perspective on the rainy day.

A sample of 75 information systems managers had an average hourly income of $40.75 with a standard deviation of $7.00. The 95% c

IrinaVladis [17]

Answer: c. 39.14 to 42.36

Step-by-step explanation:

We want to determine a 95% confidence interval for the average hourly wage (in $) of all information system managers

Number of sample, n = 75

Mean, u = $40.75

Standard deviation, s = $7.00

For a confidence level of 95%, the corresponding z value is 1.96. This is determined from the normal distribution table.

We will apply the formula

Confidence interval

= mean +/- z ×standard deviation/√n

It becomes

40.75 +/- 1.96 × 7/√75

= 40.75 ± 1.96 × 0.82

= 40.75 + 1.6072

The lower end of the confidence interval is 40.75 - 1.6072 =39.14

The upper end of the confidence interval is 40.75 + 1.6072 =42.36

An airplane with a speed of 120 knots is headed west while a 30-knot wind is blowing from 120°. Find the ground speed to the nea

SVEN [57.7K]

Answer:

Velocity of the plane relative to the ground

= [(-145.98î) + (15j)] knots

Magnitude = groundspeed = 146.75 knots

Direction = -5.9°

Step-by-step explanation:

This is a relative velocity question.

Let the velocity of the airplane relative to the wind be V(aw)

Velocity of the airplane relative to the ground = Va

The velocity of the wind relative to the ground = Vw

The relative velocity theory enables us o relate these as thus,

V(aw) = Va - Vw

Va = V(aw) + Vw

V(aw) = (-120î) knots (120 west)

For Vw, the wind is said to be blowing from 120°, reading this on a three figure bearing as angle from the north,

This gives the real direction of the wind to be 150° from the positive x-axis as shown in the attached image.

Vw = (30cos 150°)î + (30sin 150°)j

Vw = (-25.98î + 15j) knots

Va = V(aw) + Vw = (-120î) + (-25.98î + 15j)

Va = (-145.98î) + (15j)

Magnitude of Va = √[(-145.98)² + (15)²] = 146.75 knots

Direction = tan⁻¹ (-15/145.98) = -5.9°

Hope this Helps!!!
