Answer:
show the a pic
Step-by-step explanation:
B. 248,680.
C. 249,000.
D. 250,000.
A.) There is likely an association between the categorical variables because the relative frequencies are similar in value.
B.) An association cannot be determined between the categorical variables because the relative frequencies are similar in value.
C.) An association cannot be determined between the categorical variables because the relative frequencies are not similar in value.
D.) There is likely an association between the categorical variables because the relative frequencies are both close to 0.50.
If the relative frequencies are 0.48 and 0.52, we conclude that: A. There is an association between the categorical variables because they are similar in value.
A two-way frequency table can be defined as a type of table that is used for the graphical representation of frequencies (relative frequencies) that are associated with two (2) categorical variables.
This ultimately implies that, a two-way frequency table can be used to show, analyze, and examine the relationships that exists between two (2) categorical variables.
In conclusion, we can conclude that there is an association between the categorical variables because the relative frequencies have the same (similar) value, especially if theyare 0.48 and 0.52.

Answer: A
Step-by-step explanation:
Did it on edge
B New foods
C Gold
D New technology for navigation
x = 3; the diver hits the water 3 feet away horizontally from the board
x = 10; the diver jumps in the pool at 10 feet per second
x = 3; the diver jumps in the pool at 3 feet per second
The diver hits the water 3 feet away horizontally from the board.
The correct option is (b)
A quadratic equation is a second-order polynomial equation in a single variable x, ax²+bx+c=0 with a ≠ 0 .
Given function: f(x)= -x² -7x +30
Factorising f(x), we get
-x² -7x +30 =0
x² +7x -30 =0
x² +10x - 3x -30 =0
x(x+10)-3(x+10)=
(x+10)(x-3)=0
The roots of this quadratic equation are x = 3 and -10.
As, the diver is on a diving board we will not use -10.
Hence, the diver hits the water 3 feet away horizontally from the board.
