8 0

Answer:

2(x + 1)² = 0

x = -1

Step-by-step explanation:

Factorise the 2 out

2(x² + 2x + 1) = 0

2(x + 1)(x + 1) = 0

2(x + 1)² = 0

Hence x = -1

Compare the mean of the population with the mean of a sample
Artyom0805 [142]
This means that the sample mean is not systematically smaller or larger than the population mean. Or put another way, if we were to repeatedly take lots and lots (actually an infinite number) of samples, the mean of the sample means would equal the population mean.

Airplane at 19,200 feet descending at a rate of 40 feet per second. Another airplane takes off and ascends at a rate of 60 feet
AleksandrR [38]

Answer:

Step-by-step explanation:

Let t = flying time in seconds for each plane

Descending rate = 40 ft/s

Ascending rate = 60 ft/s

Descending height, hd= 19200 - 40t

Ascending height, ha = 60t

Equating hd = ha, therefore:

60t = 19200-40t

60t + 40t = 19200

100t = 19200

t = 19200/100

t = 192 seconds

h = 19200 - 192(40)

h = 19200 - 7680

= 11,520 ft.
