Answer:

180 ft³

Step-by-step explanation:

To find the volume of a right rectangular prism, the equation is length x width x height. So, you would do 2 x 6 x 15, because 24 inches is 2 feet and the rest is given. And so, 2 x 6 x 15 = 180, so your answer is 180 ft³.

(hope this helps :P)

The z-score associated with 95% is 1.96. If the sample mean is 200 and the standard deviation is 30, find the upper limit of the

ziro4ka [17]

Answer:

The upper limit of the 95% confidence interval is:

C.I_u = 200 + (58.8/ $\sqrt{n}$ )

Step-by-step explanation:

The formula is given as:

C.I = μ ± Z*σ/ $\sqrt{n}$

The upper limit => C.I_u = μ + Z*σ/ $\sqrt{n}$

The lower limit => C.I_l = μ - Z*σ/ $\sqrt{n}$

The sample size (n) is not stated in the question. Hence, we calculate the upper limit with respect to n.

The upper limit => C.I_u = 200 + 1.96*(30/ $\sqrt{n}$ )

= 200 + (1.96*30)/ $\sqrt{n}$

= 200 + 58.8/ $\sqrt{n}$

In his last game of bowling, Roberto earned a score of 241, and his average score increased from 205 to 209. What score would he

FrozenT [24]

Answer:

Robert would have needed 259 point to increase his average to 211.

Step-by-step explanation:

Averages are described by the following equations:

Initial average:

$\frac{x}{n} = 205$

$x = 205\cdot n$

Real average:

$\frac{x+241}{n+1} = 209$

$x + 241 = 209\cdot n + 209$

$x = 209\cdot n - 32$

$205\cdot n = 209\cdot n - 32$

$4\cdot n = 32$

$n = 8$

$x = 205\cdot (8)$

$x = 1640$

Expected average:

$\frac{x+y}{n+1} = 211$

$x + y = 211\cdot n+211$

$y = 211\cdot n + 211 - x$

$y = 211\cdot (8) + 211 - 1640$

$y = 259$

Robert would have needed 259 point to increase his average to 211.
