Answer:
x = 0
Step-by-step explanation:
6x – 2 + 2x = 2(4x – 3) + 4
8x - 2 = 8x - 6 + 4
8x - 2 = 8x - 2
8x = 8x + 0
0x = 0
x = 0
Answer:
7
Step-by-step explanation:
because when you divide with the coeficient it sums out to be 7
Answer:
x > -4.
Step-by-step explanation:
Solving for x by dividing -3 to both side leaving x by itself.
When dividing or multiplying a negative value that has a variable the inequality switches sides. Instead of x < -4 it is x > -4. For more information or to understand inequality search for inequality video online.
Answer: $467.21
Step-by-step explanation:
8% of 600 = 48
600 - 48 = 552
8% of 552 = 44.16
552 - 44.16 = 507.84
8% of 507.84 = 40.6272
8% of 507.84 ≈ 40.63
507.84 - 40.63 = 467.21
Answer:

Step-by-step explanation:
Given: 76,45,64,80,92
Required: Determine the standard deviation
We start by calculating the mean

Where x-> 76,45,64,80,92 and n = 5



Subtract Mean (71.4) from each of the given data

Determine the absolute value of the above result

Square Individual Result

Calculate the mean of the above result to give the variance


Hence, Variance = 255.298
Standard Deviation is calculated by
