Answer:

vol. of triangular prism = lbh/2

vol. of rectangular prism = 18 of vol. of triangular prism

18x = 18 + 14x

4x = 18

x=4.5 ft

so vol. of rectangular prism = 6 × 4 . 5 × 3 = 81 ftcube

Calculating conditional probability

laila [671]

Complete Question

Calculating conditional probability

The usher at a wedding asked each of the 80 guests whether they were a friend of the bride or of the groom.

Here are the results:

Bride :29

Groom :30

BOTH : 20

Given that a randomly selected guest is a friend of the groom, find the probability they are a friend of the bride.

P (bride | groom)

Answer:

The probability is $P(B|G) = \frac{2}{3}$

Step-by-step explanation:

The sample size is $n = 80$

The friend of the groom are $G = 30$

The friend of the groom are $B = 29$

The friend of both bride and groom are $Z = 20$

The probability that a guest is a friend of the bride is mathematically represented as

$P(B) = \frac{29}{80}$

The probability that a guest is a friend of the groom is mathematically represented as

$P(G) = \frac{30}{80}$

The probability that a guest is both a friend of the bride and a friend of the groom is mathematically represented as

$P(B \ n \ G) = \frac{20}{80}$

Now

$P(B|G)$ is mathematically represented as

$P(B|G) = \frac{P(B \ n \ G)}{P(G)}$

Substituting values

$P(B|G) = \frac{\frac{20}{80} }{\frac{30}{80} }$

$P(B|G) = \frac{2}{3}$

PLEASE HELP ILL GIVE BRAINLIEST!!

Answer:

73.12 cm

Step-by-step explanation:

The perimeter of the square is 3 sides of the square (the 4th side is not included because of the semicircle)

P square = 3 s

=3 (16)

=48 cm

The perimeter of the semicircle is 1/2 of the circumference of a circle

P semicircle = 1/2 (pi *d)

=1/2 (pi* 16)

= 8 pi

= 8 (3.14)

=25.12 cm

The total perimeter is the sum of the square and the circle

P total = P square + P semicircle

=48+25.12

=73.12 cm

Does anyone understand how to do this? If you do can you explain how I solve it and receive the answer?

UNO [17]

Answer:

slope-intercept form equation: y = x + 5

Step-by-step explanation:

you take the 2 y's, 18 and -13, then you subtract them: 18 - (-13) = 31

then you take the 2 x's, 13 and -18, subtract them too: 13 - (-18) = 31

divide those 2 sums: 31/31 = 1

so the slope is 1

then when you graph it you get an y-intercept of 5

so the equation is y = x + 5

hope this helps :)
