Answer:

8,280 watt hours

Step-by-step explanation:

1440/24 = 60 watt hours per hour

Answer:

d = 14

Step-by-step explanation:

$\sin \: 45 \degree = \frac{a}{7 \sqrt{2} } \\ \\a = 7 \sqrt{2} \sin \: 45 \degree \\ \\ a = 7\sqrt{2} \times \frac{1}{ \sqrt{2} } \\ \\ a = 7 \\ \\ \sin \: 30 \degree = \frac{a}{d} \\ \\ \frac{1}{2} = \frac{7}{d} \\ \\ d = 2 \times 7 \\ \\ d = 14$

Suppose a research firm conducted a survey to determine the average amount of money steady smokers spend on cigarettes during a

olchik [2.2K]

Answer:

option (b) 0.0228

Step-by-step explanation:

Data provided in the question:

Sample size, n = 100

Sample mean, μ = $20

Standard deviation, s = $5

Confidence interval = between $19 and $21

Now,

Confidence interval = μ ± $z\frac{s}{\sqrt n}$

thus,

Upper limit of the Confidence interval = μ + $z\frac{s}{\sqrt n}$

$21 = $20 + $z\frac{5}{\sqrt{100}}$

z = 2

Now,

P(z = 2) = 0.02275 [From standard z vs p value table]

P(z = 2) ≈ 0.0228

Hence,

the correct answer is option (b) 0.0228
