The exact solution to the equation 22x = 5x − 1 is X = - ln(5) / (2ln(2) - ln(5)).
What are mathematic equations?An algebraic equation, sometimes known as a polynomial equation, in mathematics, is a formula of the form P=0 where P is a polynomial with coefficients in some field, typically the area of the rational numbers.
The given equation is 22x=5x−1
[tex]2^2x=5^{x-1}[/tex]
Take the log pf both sides:
[tex]ln(2^2x) = ln(5^{x-1})[/tex]
Expand the logs by pulling the exponents out:
[tex]2xln(2) = (x-1)ln(5)[/tex]
Now solve for x:
Subtract ln(5)x from both sides:
2xln(2) - ln(5)x = -ln(5)
Factor x out of 2xln(2)-ln(5)x
x(2ln(2) - ln(5)) = -ln(5)
Divide both sides by (2ln(2) - ln(5))
X = - ln(5) / (2ln(2) - ln(5))
Therefore, the solution is X = - ln(5) / (2ln(2) - ln(5)).

The final scores of students in mathematics are distributed normally with a mean of 72 and a standard deviation of 10. What is the probability that a student’s score will be between 65 and 78?.
Answer:
0.8041
Explanation:
0.8041
We know that
μ=72 and σ=5
and P(65<X<78)
We can determine the Z value as (X-μ)/σ
P( 65<X<78 )=P( 65-72< X-μ<78-72)
P((65-72)/5 < Z < (78-72)/5)P((65−72)/5<Z<(78−72)/5)
P(65 < X < 78 )=P(-1.4 < Z < 1.2)P(65<X<78)=P(−1.4<Z<1.2)
To fine the Z values:
P (-1.4 < Z < 1.2 )=P ( Z < 1.2 )-P (Z < -1.4 )P(−1.4<Z<1.2)=P(Z<1.2)−P(Z<−1.4)
From the standard normal tables:
P (Z < 1.2 )=0.8849P(Z<1.2)=0.8849
to find P ( Z<-1.4)
P ( Z < -a)=1-P ( Z < a )P(Z<−a)=1−P(Z<a)
From the standard normal tables:
P ( Z < -1.4)=1-P ( Z < 1.4 )=1-0.9192=0.0808P(Z<−1.4)=1−P(Z<1.4)=1−0.9192=0.0808
Therefore
P(-1.4 < Z < 1.2 )=0.8041P(−1.4<Z<1.2)=0.8041
P (65 < X < 78)=0.8041P(65<X<78)=0.8041

A car travels the distance between logan airport and the town of framingham in 20 min. The logan express bus travels this distance in 30 min. After how long do the car and bus meet if they leave at the same time, and one travels from framingham to the airport while the other travels from the airport to framingham?.
The time the car and bus will meet if they leave at the same time, and one travels from Framingham to the airport while the other travels from the airport to Framingham is 12 minutes.
let
the distance between Logan airport and the town of Framingham = a
Car speed:
speed = distance / time
speed = a / 20
Logan express bus speed
speed = distance / time
speed = a / 30
let
the distance travelled by the car by the time they met = b
Then
the distance travelled by the bus the time they met = a - b
Therefore,
The time they met will be as follows:
speed = distance / time
time = distance / speed
b / a / 20 = a - b / a / 30
20b / a = 30(a - b) / a
cross multiply
20ab = 30(a - b)a
20ab = 30a²- 30ab
50ab = 30a²
5b = 3a
b = 3 / 5 a
Therefore,
b / a / 20 = 3 / 5 a / a / 20 = 3 / 5 a × 20 / a = 60a / 5a = 12 minutes
