Answer:

$688,75

Step-by-step explanation:

Mr Ed has for the week 40 hours in regular time because thats the agreement for him and the company, it means any other working hour is over time.

If Mr Ed has 45 hours for this week, 40 hours are regular time and 5 hours are over time for wich he receives 1,5 times his pay per hour

=(40x14,50)+(5x1,5x14,50)

=$688,75

Alenkinab [10]

Answer:

The 5-number summary is maximum= 175, minimum=126, median=150, Q₁=138 and Q₃=160.5.

Step-by-step explanation:

The given data set is

126, 128, 131, 135, 136, 140, 143, 145, 147, 148, 152, 154, 155, 156, 159, 162, 164, 166, 169, 175

The minimum value of the data is 126 and the maximum value of the data is 175.

Divide the data in two equal parts.

(126, 128, 131, 135, 136, 140, 143, 145, 147, 148), (152, 154, 155, 156, 159, 162, 164, 166, 169, 175)

The median of the data is

$Median=\frac{148+152}{2}=150$

Now divide each parenthesis in two equal parts.

(126, 128, 131, 135, 136), (140, 143, 145, 147, 148), (152, 154, 155, 156, 159), (162, 164, 166, 169, 175)

$Q_1=\frac{136+140}{2}=138$

$Q_3=\frac{159+162}{2}=160.5$

Therefore the 5-number summary is maximum= 175, minimum=126, median=150, Q₁=138 and Q₃=160.5.

Whats the measure of the angles (SHOW YOUR WORK so I can understand)

evablogger [386]

Answer:

Angle DEB: 52

Angle ADB: 30

Angle CBE: 52

Angle BEC: 38

Step-by-step explanation:

Angle DEB = 52 because triangles' angles must add up to 180. Angle ADB is 30 because it is complementary to angle BDE. Angle CBE is 52 because angle BEC is complementary to BED which is 52 degrees to BEC is 38 degrees. since the angles add up to 180, and C is 90, CBE is 52. Finally, BEC is 38 because it is complementary to BED.
