Answer:

C

Step-by-step explanation:

the measure of an inscribed angle is half the measure of its intercepted arc, so

arc DE = 2 × ∠ DFE = 2 × 18° = 36°

DF is a diameter of the circle , then

arc DEF = 180° , then

arc EF = 180° - 36° = 144°

Answer:

-19+-25f≤-144

Step-by-step explanation:

The problem says that you descended 19 below sea level. Below makes 19 into a negative. It also says that it descends 25 feet per minute. If it says per you put a variable by that number. It also says descends which means going down so that would be a negative. The problem says Lainey does not want to go over 144 feet(144 is also negative because it is below sea level) so 144 would be greater than or equal to because she does not wan to go over that amount.

Hope this helps!

The number of square feet per house is normally distributed with a population standard deviation of 154 square feet and an unkno
11111nata11111 [884]

Answer: (1500.66,1599.34)

Step-by-step explanation:

Confidence interval for population mean:

\overline{x}\pm z^*\dfrac{\sigma}{\sqrt{n}}

,where \overline{x} = Sample mean , n= Sample size, z* = critical two tailed z-value , \sigma = population standard deviation.

As per given , we have

n= 16

\sigma = 154 square feet

\overline{x}= 1550 square feet

\alpha= 1-0.80 = 0.20

Critical z-value = z_{\alpha/2}=z_{0.2/2}=z_{0.1}=1.2815

Confidence interval for population mean:

1550\pm (1.2815)\dfrac{154}{\sqrt{16}}\\\\ = 1550\pm (1.2815)\dfrac{154}{4}\\\\= 1550\pm 49.33775\\\\ =(1550-49.33775,\ 1550+49.33775)\\\\\approx (1500.66,\ 1599.34)

Required confidence interval:  (1500.66,1599.34)
