Answers
So, first you would need to multiply 6 by $35.50, then take that number and add it to the $420 to get $633.00. Then you need to multiply $310.75 by 4. After take that $1243.00 and subtract $633.00 from it to get $610.00.
the answer is: Diego would need to add at least $610 to his account to cover his checks.

Answers
Answer:
825
Step-by-step explanation:
Calculation for what The frequency in this interval is equal to:
Using this formula
Frequency=Population size*Relative frequency interval
Let plug in the formula
Frequency=5,500 observations*0.15
Frequency=825
ThereforeThe frequency in this interval is equal to:825
The frequency in this interval is equal to 825.
Given
A population is of size 5,500 observations.
When the data are represented in a relative frequency distribution, the relative frequency of a given interval is 0.15.
Frequency;The frequency is defined as the product of population size and relative frequency interval.
The following formula is used to calculate frequency in this interval is;
[tex]\rm Frequency= Population\ size\times Relative\ frequency \ interval\\\\[/tex]
Substitute all the values in the formula;
[tex]\rm Frequency= Population\ size\times Relative\ frequency \ interval\\\\Frequency= 5500\times 0.15\\\\Frequency= 55\times 15\\\\Frequency= 825[/tex]
Hence, the frequency in this interval is equal to 825.

Answers
Answer:
1. Expanded form of [tex]a^{2} . b^{3}[/tex] = (a.a).(b.b.b)
2.Exact solution x = -0.376
Step-by-step explanation:
Solution:
First we have to write the Expanded Form of [tex]a^{2} . b^{3}[/tex], Let's do it.
1) [tex]a^{2} . b^{3}[/tex] = (a.a).(b.b.b)
Hence,
Expanded form of [tex]a^{2} . b^{3}[/tex] = (a.a).(b.b.b)
2) [tex]4^{5x} = 3^{x-2}[/tex]
Now, we have to find out the exact solution of the above equation:
In order to equate the exponents, we need to make sure the bases are same. Or we simply can use logarithm to solve the above equation.
So,
We are using logarithm to solve this equation.
Let's break this down:
[tex]4^{5x} = 3^{x-2}[/tex]
Taking log on both sides.
log[tex]4^{5x}[/tex] = log[tex]3^{x-2}[/tex]
[tex]5xlog(4)[/tex] = [tex](x-2)log(3)[/tex]
Dividing both sides by log(4)
[tex]5x[/tex] = (x-2) [tex]\frac{log(3)}{log(4)}[/tex]
value of log(3) = 0.4771
value of log(4) = 0.6020
[tex]5x[/tex] = (x-2) [tex]\frac{log(0.4771)}{log(0.6020)}[/tex] =
5x = (x-2)0.792
5x = 0.792x - 1.584
by rearranging the equation, we get:
0.792x - 5x = 1.584
x(0.792 - 5) = 1.584
x(-4.208) = 1.584
x = -1.584/4.208
x = -0.376
Exact solution x = -0.376

Step-by-step explanation:
trust me i got it right on khan
Explanation:
it says $12 for each album
when you see the key word each then next beside it is the variable
also you add 200 because the key word is additional which means to add
it equals 644 because the key word is he earned a total
Tip: when you have equations underline the key words that would really help
also i just had the same problem
So therefore our equation would be: 12a + 200 = 644
and the number of albums sold is: 37
