Step-by-step explanation:

An exponential function has the form:

y = a · b^x

Are you sure you copied the problem correctly? Perhaps instead of minus, you meant multiplication:

f(x) = 620 · 7.8^x

If so, then a = 620 and b = 7.8.

For the final days before the election, the campaign manager has a total of $41,500 to spend on TV and radio campaign advertisem

Margaret [11]

Answer: There are 9 T.V. and 29 radio ads.

Step-by-step explanation:

Since we have given that

Total amount spend on TV and radio = $41,500

Total number of voters using the allocated funds = 148,000

Let the number of TV be 'x'.

Let the number of radio ads be 'y'.

Cost of each TV = $3000

Cost of each radio ads = $500

Number of voters see T.V. = 10,000

Number of voters use radio = 2000

So, According to question, it becomes,

$3000x+500y=\$41500\implies\ 30x+5y=415\\\\10000x+2000y=148000\implies 10x+2y=148$

Using the graphing method, we get that

These two lines are intersect at (9,29).

Hence, there are 9 T.V. and 29 radio ads.

A Pearson correlation (symbolized by the letter r) is normally used to summarize the association, or correlation, between two va

avanturin [10]

Answer:

False

Step-by-step explanation:

We are given the following in the question:

Pearson correlation = 1.30

Pearson coefficient:

The range of Pearson coefficient is from [-1,1]
A positive correlation means that an increase in one quantity leads to an increase in another quantity
A negative correlation means with increase in one quantity the other quantity decreases.
+1 tells about a a perfect positive linear relationship and −1 indicates a perfect negative linear relationship.

Since, the given coefficient of Pearson does not lies in the range, it cannot express relation between two quantities.

Thus, a value of 1.30 does not indicates a strong correlation.

Thus, the given statement is false.
