What does the model predict for 1900?

Mathematics
1 answer:
vagabundo [1.1K]3 years ago
3 0

Answer:

64.0% is the correct answer.

Step-by-step explanation:

As per the given scatter plot of voter turnout every year:

X axis represents the year and

Y axis represents the percentage of people who voted.

The model was predicted as per the equation:

y = -0.1271x + 307.53

<u>To find:</u> Prediction for the year 1900.

Putting the value of x=1900, the value of y will be the predicted value of the model i.e. the value of percentage of voter turnout.

\Rightarrow  y = -0.1271\times (1900) + 307.53\\\Rightarrow  y = -241.49 + 307.53\\\Rightarrow  y = -64.04\%\\OR\\y \approx 64.0\%

So, the model predicts y \approx 64.0\% for the year 1900.

Christian read 1/4 book every 2/3 per week. How many books does he read per week
Elina [12.6K]

Answer:

Christian reads 3/8th of a book a week.

Step-by-step explanation:

In order to find this amount, we need to multiply both numbers by a factor that will get the weeks to equal 1. In order to get 2/3 to equal 1, we need to multiply by 3/2 (the reciprocal). Now knowing this, we can multiply the number of books by that same fraction to get the amount of books in one week.

1/4 * 3/2 = 3/8

Which is not a characteristic of an exponential parent function?
zaharov [31]

Given:

The characteristic of an exponential parent function in the options.

To find:

Which is not a characteristic of an exponential parent function?

Solution:

The exponential parent function is:

y=b^x

Where, b>0.

At x=0,

y=b^0

y=1

It means the function passes through the point (0,1) but it does not passes through the origin. So, the statement in option A is true but the statement in option C is false.

The domain of the exponential parent function is all real numbers and the range is positive real numbers (y > 0).  So, the statements in the options B and D are true.

Therefore, the correct option is C.
