Suppose that a regression line for some data transformed with logarithms predicts that when x equals 7, log(y) will equal 1.755. what does the regression line predict y will equal when x equals 7? round your answer to the nearest whole number. a) 30 b) 2 c) 57 d) 12 d) 12

The regression line predicts that at x = 6, the value of y = 102.80.

Step-by-step explanation:

Since we have given that

When x = 6,

We need to find the value of 'y' when x=6:

Since it is logarithmic function with base 10.

So, it becomes,

Hence, The regression line predicts that at x = 6, the value of y = 102.80.

102.8

Step-by-step explanation:

If log₁₀y = 2.012, y = 10^2.012 = 102.8

4 is actually 2 I just took the test

Step-by-step explanation:

A 20,000,000

Hope my answer helped

B: 280

Step-by-step explanation:

The regression line predicts that when x equals 5:

In order to find the value for y, one must simply apply the following logarithmic property:

if :

then:

Applying it to this particular problem:

Therefore, the regression line predicts y will equal 280 when x equals 5.

Best answer is C. hope it work

Option D

The regression line predicts that at x = 4, y equals 2143

Solution:

Given that when x equals 4, log(y) will equal 3.331

To find: Find y when x equals 4

Since we have given that,

When x = 4,

We need to find the value of 'y' when x = 4

Since it is logarithmic function with base 10, Raise to power of 10 on both sides,

On rounding to nearest whole number, we get 2143

Thus Option D is correct

The regression line predicts that at x = 4, y equals 2143

Step-by-step explanation:

Given that when x equals 4, log(y) will equal 3.331

To find: Find y when x equals 4

Since we have given that,

When x = 4,

log  y = 3.331  

We need to find the value of 'y' when x = 4

Since it is logarithmic function with base 10, Raise to power of 10 on both sides,

we get

rounding to nearest whole number, we get 2143
