Answer:
"34,814" is the correct solution.
Step-by-step explanation:
The given values are:
Intercept coefficient,
![\beta_0 = 23,859](https://tex.z-dn.net/?f=%5Cbeta_0%20%3D%2023%2C859)
Production coefficient,
Units sold,
x = 3,500
Now,
The total cost will be:
⇒ ![\bar{y}=\beta_0+\beta_1 x](https://tex.z-dn.net/?f=%5Cbar%7By%7D%3D%5Cbeta_0%2B%5Cbeta_1%20x)
On substituting the estimated values, we get
⇒ ![=23,859+3.13\times 3,500](https://tex.z-dn.net/?f=%3D23%2C859%2B3.13%5Ctimes%203%2C500)
⇒ ![=23,859+10,955](https://tex.z-dn.net/?f=%3D23%2C859%2B10%2C955)
⇒ ![=34,814](https://tex.z-dn.net/?f=%3D34%2C814)
Answer:
The total length of rebar used is 21.66 meters.
Step-by-step explanation:
Given:
Ivan had cut a reinforcing bar in 19 pieces and length of each bar is 1.14 meters.
Number of pieces = 19
Length of each piece = 1.14
We need to find the total length of reinforcing bar.
To calculate the total length we will multiply number of pieces with length of each piece.
Hence,
Total length of rebar = Number of pieces × Length of each piece = ![19\times1.14 = 21..66 m](https://tex.z-dn.net/?f=19%5Ctimes1.14%20%3D%2021..66%20m)
Rounding to nearest hundred = 21.66 m
Hence the total length of reinforcing bar is 21.66 meters.
Answer:
Step-by-step explanation:
Problem:
The possible values of x in the equation (60)x = 1;
Solution:
Such a problem like this in which the highest power of the unknown is 1 will have just one solution.
60x = 1
To solve this, we take the multiplicative inverse of 60;
the multiplicative inverse of 60 =
Use this inverse to multiply both sides of the expression;
60x = 1 x
x =
