log(2t+4)=log(14-3t)
[Divide both sides with log, since both sides have log, division removes the log]
2t+4=14-3t
2t+3t=14-4
5t=10
t=2

The ratio of three numbers are 2:3:4.
Let the rational between the three numbers be x, hence the three numbers be 2x, 3x,and 4x.
If their average is 36, what are the numbers
We know the average = sum of the numbers / no. Of numbers.
(2x+3x+4x) /3=36
9x/ 3= 36
3x =36
X= 36/ 3
X= 12
The rational is 12
Answer the three number are 24, 36, and 48.

Answer:
E 0.923
Step-by-step explanation:
The Z score is a measurement used in statistics to determine the relationship between a value and a mean of a group of values measured as standard deviation from the mean. The z score (z) is given as:
, Where μ is the mean, σ is the standard deviation and x is the value.
Given that:
σ = 7, μ = 80 and x = 90
From the normal distribution table, P(X < 90) = P(z < 1.43) = 0.923
Answer:
a ) If r ⇒ p
If q ⇒ p
r ∪ q
If r∪p ⇒ ¬ r
∴ s
b) The argument is invalid
Step-by-step explanation:
The argument is invalid because we do not with precision if b), because we do not have enough information about it, and this is because the previous sentences does not mention information about the donkey. We cannot infer something when we do not have enough information.
