\frac{4^3\times4^{-1}\times5^{-2}}{4^4\times5^{-3}\times5^0}=\frac{4^{3-1}\times5^{-2}}{4^4\times5^{-3+0}}\\=\frac{4^{2}\times5^{-2}}{4^4\times5^{-3}}=4^{2-4}\times5^{-2-(-3)}\\=4^{-2}\times5^{1}=\frac{5}{4^2}\\=\frac{5}{16}

nata0808 [166]

Answer:

y = -¼│x − 5│+ 3

Step-by-step explanation:

y = a│x − h│+ k

(h, k) is the vertex of the absolute value graph.  In this case, it's (5, 3).

y = a│x − 5│+ 3

One point on the graph is (1, 2).  Plug in to find the value of a.

2 = a│1 − 5│+ 3

2 = 4a + 3

a = -¼

Therefore, the graph is:

y = -¼│x − 5│+ 3

The mean hours of sleep that students get per night is 5 hours, the standard deviation of hours of sleep is 1 hour, and the dist
shepuryov [24]

Answer:

.For about 68% of students, nightly amount of sleep is between __4____and ___6__ hours.For about 95% of students, nightly amount of sleep is between __3____and __7___ hours.For about 99.7% of students, nightly amount of sleep is between ___2___and __8___ hours.                    

Step-by-step explanation:

The empirical rule tells us that for normal distributions,

68% of data lie within one standard deviation of the mean.

Thus, 68% of data lie within \bar{x} \pm s

⇒ 5 ± 1 = (4, 6) hours

Similarly, 95% of data lie within two standard deviation of the mean.

Thus, 95% of data lie within \bar{x} \pm 2s

⇒ 5 ± 2 = (3, 7) hours

99.7% of data lie within one standard deviation of the mean.

Thus, 99.7% of data lie within \bar{x} \pm s

⇒ 5 ± 3 = (2, 8) hours
