Answer:

-7 is negative so it cannot be a natural number, but it is an integer. An integer is a whole number, this means that it does not have any decimal places or fractions. However, a natural number must be a whole non-zero number and positive. This is because natural numbers are numbers found naturally in measurements or in counting. Additionally, all natural numbers are integers but not all integers are natural numbers. For example, -3 would be an integer, 9 would be an integer and a natural number, and 7.6 would be neither.

Answer:

Natural Numbers are basically "counting numbers". If I ask you to start counting, you'll start at 1, then 2, then 3, and so on. It doesn't include 0 or any negative numbers because you wouldn't start from -10 when asked to count.

Vem created a website for his school's sports teams. He has a hit counter on his site that lets him know

AlladinOne [14]

Using technology, the linear regression equation by fitting the data in the table is ŷ = 2.4x + 11. The predicted number of hits they will be recorded on day 15 is 47.

Using technology such as a regression calculator or excel ;

The regression equation which models the data is ;

ŷ = 2.4x + 11

Slope = 2.4 ; intercept = 11

The number of hits recorded on day 15 :

Substitute x = 15 into the equation :

ŷ = 2.4(15) + 11

ŷ = 47

Therefore, the predicted number of hits on day 15 is 47 hits.

A finite arithmetic sequence has 12 termsThe last term is 100 and the common difference is 3. What is the first term?

ololo11 [35]

Answer:

Step-by-step explanation:

From the question given above, the following data were obtained:

Number of terms (n) = 12

Last term (L) = 100

Common difference (d) = 3

First term (a) =?

We can obtain the first term of the arithmetic sequence as follow:

L = a + (n – 1)d

100 = a + (12 – 1)3

100 = a + (11)3

100 = a + 33

Collect like terms

100 – 33 = a

a = 67

Therefore, the first term of the arithmetic sequence is 67
