Step-by-step explanation:
Exponential equation :


Logarithmic equation :

So we have to find out what x is before we can solve for either angle
because vertical angles are always congruent we can set the two equations to equal each other and solve for x
so
-3x + 58 = x - 2
we need to get all the x terms on one side before we can solve for x so let's add 2 to both sides to get x alone on the right side
now we have
-3x + 60 = x
now we add 3x to both sides
60 = 4x
we isolated the terms and now we can solve for x by dividing both sides by 4
15 = x
so if x = 15 we need to plug that in to both equations to check our work
C = -3(15) + 58
C = 13
D = 15 - 2
D = 13
x does in fact equal 15 because both equations got the same answer and we found out that angle D = 13
Well if you divide the two fractions the answer would be 2
Answer:
im pretty sure its 2 answers
both a and c
hope this helps!!
Answer:
<u>The standard error of distribution for n = 4 is 5 and for n = 25 is 2.</u>
Step-by-step explanation:
1. Let's review the information given to us for solving the question:
Population mean = 72
Standard deviation = 10
Sample₁ = 4
Sample₂ = 25
2. For finding the standard error of the mean, we use the following formula:
Standard error = Standard deviation / √Size of the sample
Standard error for Sample₁ = 10/√4
<u>Standard error for Sample₁ = 10/2 = 5</u>
Now, let's find the standard error for Sample₂
Standard error for Sample₂ = 10/√25
<u>Standard error for Sample₂ = 10/5 = 2</u>
