Answer:

196ft^2

Step-by-step explanation:

direct the diagram as shown in my image attachment

A = 1/2 x (18-(9-7)) x (6+8) = 112ft^2

B = 2 x (6+8) = 28ft^2

C = 7 x 8 = 56ft^2

total area = 112 + 28 + 56 = 196ft^2

Answer:

196 ft²

Explanation:

Consider the given image.

Area of ΔABC

= ½bh

= ½ × (18 ft + 7 ft - 9 ft) × (8 ft + 6 ft)

= ½ × 16 ft × 14 ft

= 8 ft × 14 ft

= 112 ft²

Area of rectangle BEDC

= lw

= (8 ft + 6 ft) × (9 ft - 7ft)

= 14 ft × 2 ft

= 28 ft²

Area of rectangle EFGH

= lw

= 8 ft × 7 ft

= 56 ft²

Total area of the figure

= Area of ΔABC + Area of rectangle BEDC + Area of rectangle EFGH

= 112 ft² + 28 ft² + 56 ft²

= 196 ft²

sergij07 [2.7K]

Answer:

Maximum number of people is 35

Step-by-step explanation:

With a total of $160 you have to pay for the bus and all the people. The bus cost $90 so you subtract that from the 160 because you bought (or rented) the bus. Then you have $70 left to pay for everyone's tickets. If each ticket is $2 then you can buy 35 tickets in total because 70 divided by 2 = 35.

Recently, TWA reported an on-time arrival rate of 78.4%. Assume that a later random sample of 750 flights results in 630 that ar
WINSTONCH [101]

Answer:

Step-by-step explanation:

1. Null hypothesis: u <= 0.784

Alternative hypothesis: u > 0.784

2. Find the test statistics: z using the one sample proportion test. First we have to find the standard deviation

Using the formula

sd = √[{P (1-P)}/n]

Where P = 0.84 and n = 750

sd =√[{0.84( 1- 0.84)/750]}

sd=√(0.84 (0.16) /750)

SD =√(0.1344/750)

sd = √0.0001792

sd = 0.013

Then using this we can find z

z = (p - P) / sd

z = (0.84-0.784) / 0.013

z =(0.056/0.013)

z = 4.3077

3. Find the p value and use it to make conclusions...

The p value at 0.02 level of significance for a one tailed test with 4.3077 as z score and using a p value calculator is 0.000008254.

4. Conclusions: the results is significant at 0.02 level of significance suck that we can conclude that its on-time arrival rate is now higher than 78.4%.
