Answer:

B) 3/4

Step-by-step explanation:

The conditional probability of B given A (B|A) is P(A ∩ B) / P(A), when P(A) > 0 (Probability of the intersection of A and B over the Probability of A).

in our case, P(A ∩ B is the amount of people who can snowboard and surf, which according to the picture is 36

P(A) is the amount of people who can snowboard, which from the picture is 48

This means our conditional probability is 36/48, which when simplified is 3/4.

Answer:

Volume = 72 cm³

Step-by-step explanation:

Volume = a^2\frac{h}{3}

<u><em>Where a = 6, h = 6</em></u>

Volume = (6)^2\frac{6}{3}

If neil, weighing 150 pounds, jumps with an initial velocity of 8ft/sec, calculate his hang time on the earth as well as his han
sashaice [31]

we use the following formula to calculate height, 'h', under the effect of gravity: 


h = vt - (1/2)gt^2, where g = 9.8m/s^2 and 't' represents time in seconds


8 ft/s * 0.3048 = 2.4384 m/s


we treat mass as inconsequential to the problem, considering only the effect of initial velocity and gravitational pull


to find his 'hang time' we solve for h=0, knowing that t=0 will be the first value (before the jump): 

0 = 8(0.3048)t - (9.8/2)t^2

solving for 't' we have t=0.497


the 'hang time' will be approximately 0.5 seconds, or 1/2 of a second


the maximum height will be 0.2488m, or 0.816 feet, or 9.8 inches


on the moon, the hang time and height will increase by a factor of 6

hang time: approximately 3 seconds on the moon

maximum height: approximately 2.4 feet

Question 1 Hannan wants to estimate the number
Mama L [17]

Answer:

2000 eels

Step-by-step explanation:

Let us represent the total estimate of the eels = x

She returns the 50 eels to the lake.

The next day Hannah catches 400 eels, of these 400 eels, 10 are ringed.

To solve the above question, we have the following:

50/x = 10/400

Cross Multiply

10x = 50 × 400

x = 50 × 400/10

x = 2000 eels

Therefore, the total estimate of the eels in the lake = 2000 eels
