Answer:

g(n)=80×3^(n-1)

Step-by-step explanation:

First term (a)=80

The ant population tripled every week.

So, the population of ant after 1st week will be (80 × 3) = 240

After 2 weeks, the population triples again.

We have, (240 × 3) = 720

Common ratio (r)=720/240

=3

r=3

The ants population is increasing in a geometric progression

A geometric progression is given by

g(n)=a × r^(n-1)

Substitute values of a and r to get the explicit formula

g(n)=a × r^(n-1)

g(n)=80×3^(n-1)

Feliz [49]

Answer:

The researcher should use correlation analysis for his studies.

What is correlation?

Correlation is a statistical tool used to quantify the degree to which two variables are related. Through the correlation analysis, you evaluate correlation coefficient that tells you how much one variable changes when the other one does. Correlation analysis provides you with a linear relationship between two.

Types of correlation

1. Positive, Negative or Zero Correlation:

2. Linear or Curvilinear Correlation:

3. Scatter Diagram Method:

4. Pearson's Product Moment

Coefficient of Correlation:

5. Spearman's Rank Correlation

Which expression is represented by the phrase "the square of y decreased by the quotient of 28 and 7?
agasfer [191]

Answer:

y^{2}-4

Step-by-step explanation:

We are given the statement,

'The square of y decreased by the quotient of 28 and 7'.

i.e. Subtracting the quotient \frac{28}{7} = 4 from y^{2}.

i.e. y^{2}-4

Hence, the expression which represents the given statement is y^{2}-4.

X = 38°

Step-by-step explanation:

The sum of the inner angles of a triangle is 180 degrees

Then.. :

136+ x= 180

180- 136= x

X= 44

88 + 44 + x = 180

142+ x = 180

X= 180-142

X = 38°

Please help. 10 points and brainliest.
Snezhnost [94]

Answer:

\frac{a^2}{b^2}

Step-by-step explanation:

Apply the exponent rule a^b*a^c=a^b+c to a

a^4*a^-^2=a^4^-^2=a^2

b^3a^2b^-^5

Apply the exponent rule to b

b^3*b^-^5=b^3^-^5=b^-^2

Apply the exponent rule a^-^b=\frac{1}{a^b}

b^-^2=\frac{1}{b^2}=\frac{1}{b^2}a^2=\frac{a^2}{b^2}
