6)The experimental probability is 39%.(39/100(100)).

7) The theoretical probability is theoretical. This is when something should happen without taking external forces into account. Experimental probability is taking the external forces into account which is why the probability is not as clean cut.

The theoretical probability should be 33%.
The experimental probability is actually 39%.

What must the measure of angle LMN be? m∠LMN = °

luda_lava [24]

Both 25x and 22x + 9 have the same answers. So you set those two equal to each other.
$25x = 22x + 9$
Subtract 22x from both sides.
$3x = 9$
and you're left with this.
Next, divide 3 from both sides.
$x = 3$
re-insert 3 into one of the equations.
$25(3) = 75$
add up both angles
$75 + 75 = 150$
all angles (for quadrilaterals)added up equals 360.
$150 + 2x = 360$
solve for x. Subtract 150 from both sides.
$2x = 210$
and divide 2 from both sides
$x = 105$
AngleLMN= 105

Helo me please please

drek231 [11]

i) Area = length x width

=250 x 100

= 25000 cm2

ii) it is a square so the sides are equal

Area = 10 x 10

= 100cm2

iii) 25000/100

250 tiles will be needed

Iv) one tile is 4.75 dollars

Total tiles are 250

Cost for tiling

=250 x 4.75

=1187.5

Hope this helps

After a new $28,000 car is driven off the lot, it begins to depreciate at a rate of 18.9% annually.

Rainbow [258]

Answer:

Step-by-step explanation:

We get 0.811 as our depreciating value because we take 18.9% and turn it into a decimal. Then, we subtract that from 1. If we did 0.189 instead, it would depreciate at a rate of 81.1% annually.

What is 2 3/5 + 1 3/5

Vlada [557]

Answer: 4 1/5

Step-by-step explanation:

Rewriting our equation with parts separated

=2 + 3/5 + 1 + 3/5

Solving the whole number parts

2 + 1= 3

Solving the fraction parts

3/5 + 3/5 = 6/5

Simplifying the fraction part, 6/5,

6/5 = 1 1/5

Combining the whole and fraction parts

3 + 1+ 1/5 = 4 1/5

Solution by Formulas

converting mixed numbers to fractions, our initial equation becomes,

13/5 + 8/5

Applying the fractions formula for addition,

=(13 × 5) + (8 × 5)/5 × 5

=65+40 / 25

=105/25

Simplifying 105/25, the answer is

=4 1/5
