First, find the height of the pyramid using the volume formula.
Then use the Pythagorean theorem to find the slant height.

V = (1/3)Ah

48 = (1/3)(6^2)h

144 = 36h

h = 4

Since the side of the base is 6 in., half the side is 3 in.
The height of the pyramid is 4 in.
Call the slant height S.

3^2 + 4^2 = S^2

9 + 16 = S^2

25 = S^2

S = 5

Answer: The slant height is 5 in.

Put the following equation of a line into slope-intercept form, simplifying all fractions

Varvara68 [4.7K]

Answer:

y = 2x - 5

Step-by-step explanation:

Slope intercept form: y = mx + c

3y - 6x = -15

3y = 6x - 15

$\frac{3y}{3}=\frac{6x}{3} -\frac{15}{3}\\\\y =2x - 5$

Serga [27]

Answer:

0.0159

Step-by-step explanation:

Given that a common practice of airline companies is to sell more tickets for a particular flight than there are seats on the plane, because customers who buy tickets do not always show up for the flight.

Here if X is the no of persons that do not show up, then X is binomial as each trial is independent with p = 0.04 and n =150 (no of tickets sold)

The plane is overbooked if more than 150 show up

i.e. less than 2 do not show up

Hence the probability that the airline overbooked this flight

= $P(X$
