The answer is 58 I think 166-8= 158
48/4= 12 pens per box
12*9 = 108 pens in 9 boxes
Answer: 0.96875
Step-by-step explanation:
Probability of obtaining at least one tail on a toss of coin 5 times ;
P(success) in a coin toss = 1/2 = 0.5
Using the binomial distribution formula :
P(x) = nCx * p^x * (1 - p)^(n-x)
P(at least one tail) = 1 - p(0 tails)
P( 0 tails) = 5C0 * 0.5^0 * 0.5^(5-0)
= 1 * 1 * 0.03125
= 0.03125
P(at leat 1 tail) = 1 - 0.03125
P(atleast 1 tail) = 0.96875
we conclude that the solution for the given algebraic expressions are:
- J = -5
- s = -106
- t = 38
- r = -60
- a = 57

How to solve these algebraic expressions?</h3>
Here we have some simple algebraic expressions:
The first one is:
-25/J = 5
We want to solve this for J.
Remember that we can perform the same operation in both sides of the equation, then we cans tart by multiplying both sides by J.
(-25/J)*J = 5*J
-25 = 5*J
Now we can divide both sides by 5, so we isolate J:
(-25)/5 = (5*J)/5
-5 = J
We conclude that the solution is J = -5.
Now, similarly for the other equations we have that:
16 + s = -90
Here we subtract 16 in both sides:
s = -90 - 16 = -106
13 + t = 51
Here we subtract 13 in both sides:
t = 51 - 13 = 38
r/10 = (-6)
Here we multiply both sides by 10:
r = (-6)*10 = -60
a + (-12) = 45
Here we add 12 in both sides:
a = 45 + 12 = 57
Then we conclude that the solution for the given algebraic expressions are:
- J = -5
- s = -106
- t = 38
- r = -60
- a = 57
