Answer:

2.5x10-14

Step-by-step explanation:

0.0000254=2.54*10^-5

0.0000035=3.5*10^-5

0.000255=2.55*10^-4

multiplying them all because volume is equals to

l*b*h

which gives

2.26695×10^-14

elixir [45]

Answer:

The answer to your question is: letter a

Step-by-step explanation:

data

balls diameter = 0.75 in then radius = 0.375 in

rectangular prism =   length = 3 in width = 3 height = 7.5 in

Formula

Rectangular prism volume = l x w x h = 3 x 3 x 7.7 = 67.5 in³

ball volume = 4/3 (3.1416)(r³) = 4/3 (3.1416)(0.375)³ = 0.220in³

 but   0.220in³ ------------------- 100 %

             x          -------------------  190%

  x = 0.418 in³

Finally divide the rectangular prism volume by ball volume

# of balls = 67.5 / 0.418 = 161.4 ≈ 160

Hello from MrBillDoesMath!

Answer:

Choice C, 14



Discussion:

The question is a bit obtuse bust as I  understand it if we take x = 14 (Choice C). determined by trial and error, then


sqrt(91x) =

sqrt ( 91 * 14) =

sqrt (1274 ) =

sqrt (49 *26) =                    => as sqrt(49) = 7 we can simplify the expression

= 7 sqrt(26)


Thank you,

MrB

Answer:

For this case they want to proof if the proportion of readers own a Rolls royce is less than 0.29 and that wuld be the alternative hypothesis. The complement would represent the null hypothesis. Then the system of hypothesis for this case are:

Null hypothesis: p \geq 0.29

Alternative hypothesis: p< 0.29
