Which situation represents causation rather than correlation?
A. as the number of injured players on the sports team increases the number of fans attending the teams game increases
B. as more swimsuits are sold by department stores more sailboats are rented at the marina
C. as more people carry their umbrellas to work more people dress and heavier clothing
D. as a total number of family member increases the amount of money that the family spends on food increases
Answer: D. as a total number of family member increases the amount of money that the family spends on food increases
Step-by-step explanation:
Correlation is used to describe the 5kinf of relation between two variables whereas causation is relationship between the cause and effect.'i.e. independent variable acts like a cause to effect the dependent variable.
This can be seen only in Option D. as it is very obvious that increase in family member will increase the cost of food.
Hence, there is direct effect of number of people on food's cost.
Rest of options represents correlation but not causation .
Hence, the correction option is D.

Step-by-step explanation:
After all markdowns and discounts, Charlene's prom dress cost her $22 before tax. The dress was on a rack labeled "50% off lowest marked price," and the lowest marked price was already a 75% reduction from the original price. What was the original price of the dress?
Answer: $88.
Step-by-step explanation:
given data:
The cost of the dress for the prom = $22
label of the rack the dresss was on = 50%.
lowest marked price for the dress = 75%.
Solution:
if the lowest marked price of the cloth was already 75%.
and the current cost of the clothe is $22
the original cost of the cloth would be
100% – 75% = 0.25%
= $22 * 100 / 0.25%
= $88.
The original cost of the dress was $88
Answer:
$88

sry i dont know which are the consecutive exterior angles
but i hope you understood
<2 and <13 are alternate interior angles
Reason: At the opposite sides of the transversal and fall between
<4 and < 11 are co-interior angles
Reason: Same side of the transversal and fall between the two parallel lines
<1 and <16 do not have any direct relationship
<3 and <12 are co-exterior angles
Reason: Same side of the transversal but each of them are outside the parallel lines
<3 and <5 are co-interior angles
Reason: Same side of the transversal and fall between the two parallel lines
<14 and 16 are corresponding angles
Reason: They are at corresponding sides of the parallel lines to the transversal
<1 and <3 are corresponding angles
Reason: They are at corresponding sides of the parallel lines to the transversal
<5 and <10 are alternating exterior angles
Reason: Alternate side of the transversal but each of them are outside the parallel lines

9 is 10 times the value of the 9 in 329,513
2 is 110 the value of the 2 in 7,562
6 is 110 the value of the 6 in 4.68
Answer:
498,173.26.
Step-by-step explanation:
The place value of 9 in the number 3, 29,513 = 9000
In the required number,
Place value of 9 is 10 times of the value of 9 in 329, 513 = 9000 * 10 = 90,000
The value of 2 is one-tenth of 2 in 7562 = 2/10 = 0.2
The value of 6 is one-tenth value of 6 in 4.68 = 0.60/10 = 0.06
Thus, the required number would be 498,173.26 as the other numbers do not justify the above conditions of having 9 at ten thousand place, 2 at tenth, and 6 in hundredth place.

A newborn baby has about 26,000,000,000 cells. An adult has about 1.9 X 10^3 times as many cells as a newborn. About how many cells does an adult have? Write your answer in scientific notation.
Answer:
1900
Step-by-step explanation:
26,000,000,000 cells = 2.6 x 10^10 (baby cells)
An adult has about 4.94 times 10 to the thirteenth power
(4.94 x 10^13)/(2.6 x 10^10) = 1.9 x 10^3 = 1900
