The value of <em>a</em> and <em>b</em> for the data values of stalk of corn using the logarithmic regression is -76.2038 and 37.6735 respectively.
<h3>What is logarithmic regression?</h3>
Logarithmic regression is a type of regression which is used to model the statement in which the growth or decay initially at rapid rate, and then slow down with respect to time.
The data of the table for the day and height of the stalk of corn is listed below.
Day (<em>x</em>) 9 12 22 40
Height (<em>y</em>) in 5 17 45 60
Mean of x values,
![m_x=\dfrac{9+12+22+40}{4}\\m_x=17.5581](https://tex.z-dn.net/?f=m_x%3D%5Cdfrac%7B9%2B12%2B22%2B40%7D%7B4%7D%5C%5Cm_x%3D17.5581)
Mean of y values,
![m_y=\dfrac{5+17+45+60}{4}\\m_y=31.75](https://tex.z-dn.net/?f=m_y%3D%5Cdfrac%7B5%2B17%2B45%2B60%7D%7B4%7D%5C%5Cm_y%3D31.75)
For the above table, the value of correlation coefficient is 0.99133. For these values, the logarithmic regression can be given as,
![y = -76.2038+37.6735\ln(x)](https://tex.z-dn.net/?f=y%20%3D%20-76.2038%2B37.6735%5Cln%28x%29)
Compare it with the following logarithmic regression equation, we get
![y = a+b\ln(x)](https://tex.z-dn.net/?f=y%20%3D%20a%2Bb%5Cln%28x%29)
![a=-76.2038\\b=37.6735](https://tex.z-dn.net/?f=a%3D-76.2038%5C%5Cb%3D37.6735)
Hence, the value of <em>a</em> and <em>b</em> for the data values of stalk of corn using the logarithmic regression is -76.2038 and 37.6735 respectively.

The answer is c. My dude good luck
8y+4 = 2(y-1)
8y+4 = 2y-2
8y-2y+4 = -2
6y+4 = -2
6y = -2-4
6y = -6
y = -1

Answer:
There are 101 marbles in each bag and 10 marbles left over
Step-by-step explanation:
We can use the modulus to find out left over. The modulus is the remainder of the division from one number by another number. For example, 7 % 2 = 1. When you divide 7 by 2, division is 3 but the remainder is 1.
1525 % 15 = 10 marbles are left over
Now, we know that 1525 - 10 = 1515 marbles are equally put into each bag. That means each bag contains
1515 / 15 = 101 marbles
