Answer:

h=55.4 mm

Step-by-step explanation:

Area of a triangle = \frac{bh}{2} where b is base and h is height

now just plug and chug

227.14 = 8.2h/2

227.14=4.1h

h=227.14/4.1

h=55.4

check answer:

55.4 * 8.2 /2 = 227.14, as proven by my calculator

There are 15 identical pens in your drawer, nine of which have never been used. On Monday, yourandomly choose 3 pens to take wit
DaniilM [7]

Answer: p = 0.9337

Step-by-step explanation: from the question, we have that

total number of pen (n)= 15

number of pen that has never been used=9

number of pen that has been used = 15 - 9 =6

number of pen choosing on monday = 3

total number of pen choosing on tuesday=3

note that the total number of pen is constant (15) since he returned the pen back .

probability of picking a pen that has never been used on tuesday = 9/15 = 3/5

probability of not picking a pen that has never been used on tuesday = 1-3/5=2/5

probability of picking a pen that has been used on tuesday = 6/15 = 2/5

probability of not picking a pen that has not been used on tuesday= 1- 2/5= 3/5

on tuesday, 3 balls were chosen at random and we need to calculate the probability that none of them has never been used .

we know that

probability of ball that none of the 3 pen has never being used on tuesday = 1 - probability that 3 of the pens has been used on tuesday.

to calculate the probability that 3 of the pen has been used on tuesday, we use the binomial probability distribution

p(x=r) = nCr * p^{r} * q^{n-r}

n= total number of pens=15

r = number of pen chosen on tuesday = 3

p = probability of picking a pen that has never been used on tuesday = 9/15 = 3/5

q = probability of not picking a pen that has never been used on tuesday = 1-3/5=2/5

by slotting in the parameters, we have that

p(x=3) = 15C3 * (\frac{2}{5})^{3} * (\frac{3}{5})^{12}

p(x=3) = 455 * 0.4^{3} * 0.6^{12}

p(x=3) = 455 * 0.064 * 0.002176

p(x=3) = 0.0633

thus probability that 3 of the pens has been used on tuesday. = 0.0633

probability of ball that none of the 3 pen has never being used on tuesday  = 1 - 0.0633 = 0.9337

The average swimming pool has a water capacity of 375,000 liters. Use dimensional analysis to show how many milliliters of water
Agata [3.3K]

Answer:

375,000,000 milliliters of water is in the pool.

Step-by-step explanation:

We know

1 liters = 1000 milliliters

hence to convert liter in to milliliter we have to multiply the liter unit  with 1000 to get the milliliter

we have to find value of 375,000 liters in milliliters

to get that we multiply both side by 375,000

1* 375,000 liters = 1000* 375,000 milliliters

thus,

375,000 liters = 375,000,000 milliliters

thus, there is 375,000,000 milliliters of water is in the pool.
