Answer:
The probability you see a dolphin or a whale on both days is 0.64
Step-by-step explanation:
Consider the provided information.
It is given that the brochure claims an 80% chance of siting a dolphin or a whale.
The provided claims can be written as: 80% or 0.80
Let say first day you see a dolphin or a whale and same happen on the next day.
Thus, the probability is:
0.80 × 0.80 = 0.64
Probability of see them on both days is 0.64
Hence, the probability you see a dolphin or a whale on both days is 0.64
The answer is 62,442,656
scientific notation its 6.2442656 * 10 to the 7th power
word form its 62 million 442 thousand 656
we know that
<u>The correlation coefficient</u> is a number between
and
that represent the linear dependence of two variables or sets of data
Using the function CORREL in a excel tool, calculate the correlation coefficient (r)
see the attached table
the correlation coefficient for the data in the table is equal to 
therefore
<u>the answer is</u>

Explanation:
Step 1) Add

2×4=8 because 2 and 4 would be the addends and their less than 5 and it equal an answer between 4 and 10
