is the answer b ?? i could be wrong , but i thought that you'd have a 50% chance when flipping coins .
vovikov84 [41]

The experimental probability is how many times it landed on heads over the amount of times it was flipped.


The coin landed on heads 32 times out of 50 flips which is 32/50 which equals 0.64, which is 64%


The answer is D.

The maximum depth dmax that a diver can snorkel is set by the density of the water and the fact that human lungs can function ag
postnew [5]

Answer:

17 cm

Step-by-step explanation:

1. Depth in fresh water

p(water) = hρg

d(max) = h = p/(ρg)

Convert atmospheres to pascals

0.056 atm × 101 325 Pa/1 atm = 5670 Pa

h = 5670 Pa/(1000 kg·m⁻³ × 9.806 m·s⁻²) × (1 kg·m⁻¹s⁻²/1 N) = 0.579 m

2. Depth in Dead Sea

d(max) = 5670/(1400 × 9.806) = 0.413 m

3. Difference

Difference = 0.579 – 0.413 = 0.17 m  = 17 cm

The difference in d(max) is 17 cm.

Is anyone good at geometry???
zhenek [66]
Hey there Smarty!

This would be considered to be a (acute angel) which in this case, we would have to make sure that this whole triangle would equal less than 270 because each angle would be less than 90°

If we add/multiply \boxed{(90+90+90) \ or \ (90*3) = 270}.

So, we would have to know that was ever this would all add up to be, this would have to be less than 270°

\left[\begin{array}{ccc}\boxed{\boxed{(2.5+5) \\ \\ (2.5*2.5) \\ (2.5-2) \\ (2.5-1) \\}} \\ \\ this \ would \ be \ why \ I \ would \ say \\ that \ this \ would \ be \ the \ answer \end{array}\right]

I truly hope this helps, and also, it's kind of my 
 first time doing this I hope this would be helpful.

7th grade math problem
natulia [17]

Answer:

x=9

JKL = 108 degrees

KLJ = 27 degrees

LJK = 45 degrees

Step-by-step explanation:

Add all the values of the triangle angles together to get 20. Then divide 180 by  20 to get 9 (The sum of all the angles in the triangle always equals 180 degrees).

JKL = 12x = 12(9) = 108

KLJ = 3x = 3(9) = 27

LJK = 5x = 5(9) = 45
