Answer:

Surface area of the rectangular prism= $168 yards^2$

Step-by-step explanation:

Given Dimensions of the rectangular prism are:

$Length(L)= 9 yards\\\\Width(w)=2 yards \\\\Height(H)= 6 yards$

Surface Area of a rectangular prism=

$2(L*W+W*H+H*L)\\\\ =2(9*2+2*6+6*9)\\\\ =2(18+12+54)\\\\ = 2(84)\\\\$

= $168 yards^2$

The surface area of the rectangular prism is $168 yards^2$

The following data represent the flight time (in minutes) of a random sample of seven flights from one city to another city. 28

anzhelika [568]

Answer:

$Range = 281-256= 25$

In order to calculate the sample deviation we need to calculate the mean given by:

$\bar X = \frac{\sum_{i=1}^n X_i}{n}$

And replacing we got:

$\bar X= 265$

And the standard deviation can be calculated with this formula:

$s = \sqrt{\frac{\sum_{i=1}^n (X_i -\bar X)^2}{n-1}}$

And replacing we got:

$s = 8.426$

Step-by-step explanation:

For this case we have the following data given:

281, 269, 259, 265, 256, 259, 266

The range is defined as:

$Range = Max -Min$

And if we replace we got:

$Range = 281-256= 25$

In order to calculate the sample deviation we need to calculate the mean given by:

$\bar X = \frac{\sum_{i=1}^n X_i}{n}$

And replacing we got:

$\bar X= 265$

And the standard deviation can be calculated with this formula"

$s = \sqrt{\frac{\sum_{i=1}^n (X_i -\bar X)^2}{n-1}}$

And replacing we got:

$s = 8.426$

According to the general equation for conditional probability, if (image attached)

katrin2010 [14]

Answer: Option A

$P(A|B) = \frac{40}{49}$

Step-by-step explanation:

In a probabilistic experiment, when two events A and B are dependent on each other, then the probability of occurrence A since B occurs is:

$P(A|B) = \frac{P(A\ and\ B)}{P(B)}$

Then if $P(A\ and\ B) = \frac{5}{7}$ and $P(B) = \frac{7}{8}$ then:

$P(A|B) = \frac{\frac{5}{7}}{\frac{7}{8}}\\\\P(A|B) = \frac{40}{49}$
