Answer: 24

Step-by-step explanation:

Given

2x^4+2y^4+2z^4=144

dividing whole equation by 2, we get

\Rightarrow x^4+y^4+z^4=72

Mean is given by the sum of the value of entities divided by the total no of entities

\Rightarrow \text{Mean}=\dfrac{x^4+y^4+z^4}{3}\\\\\Rightarrow \text{Mean}=\dfrac{72}{3}\\\\\Rightarrow \text{Mean}=24

You draw 4 cards from a deck of 52 cards with replacement. What are the probabilities of drawing a black card on each of your fo
lawyer [7]

Solution:

As, in a pack of cards, there are 26 black cards and 26 red cards.

Probability of an event = \frac{\text{total favorable outcome}}{\text{total possible outcome}}

Probability of drawing a black card from a pack of 52 cards = \frac{26}{52}=\frac{1}{2}

As each card drawn is replaced,Each black card draw is an independent with another black card draw.

Probabilities of drawing a black card on each of  four trial=

  \frac{1}{2}\times \frac{1}{2}\times \frac{1}{2}\times \frac{1}{2}=[\frac{1}{2}]^4

katen-ka-za [31]

Answer:

min = 64.2m ; max = 86.2m

Step-by-step explanation:

38.25m \leq AC < 38.35m&#10;\\ 11.5deg \leq B < 12.5deg&#10;\\ 19.5deg \leq D < 20.5deg

d_{min} = BC_{LB} - CD_{UB}&#10;\\ \\ d_{min} = \frac{AC_{LB}}{tan(B)_{UB}} - \frac{AC_{UB}}{tan(D)_{LB}}&#10;\\ \\ d_{min} = \frac{38.25}{tan(12.5)} - \frac{38.35}{tan(19.5)}&#10;\\ \\ d_{min} = 64.2m (3sf)


d_{max} = BC_{UB} - CD_{LB}&#10;\\ \\ d_{max} = \frac{AC_{UB}}{tan(B)_{LB}} - \frac{AC_{LB}}{tan(D)_{UB}}&#10;\\ \\ d_{max} = \frac{38.35}{tan(11.5)} - \frac{38.25}{tan(20.5)}&#10;\\ \\ d_{max} = 86.2m (3sf)
