Henry collected data on the favorite type of food of the students of two grades. the table below shows the relative frequencies of rows for the data collected:
burger sandwich noodles total
grade 8 0.50 0.10 0.40 1.00
grade 9 0.53 0.20 0.27 1.00
total 0.36 0.32 0.32 1.00

based on the data, which statement is most likely correct?
a) in grade 9, 53 students liked burgers.
b) in grade 9, 73% of students liked noodles.
c) in grade 8, 40% of students liked noodles.
d) in grade 8, 10 students liked sandwiches.

C) In Grade 8, 40% of students liked noodles.

Step-by-step explanation:

Given is the table as follows

Grade            Burger    Sandwich        NOodles   Total

8                      0.50        0.10                       0.40     1.00

9                      0.53         0.20                     0.27     1.00

The entries are showing the relative frequencies of gradewise favourite food

We have to check which one is right from the given 4 statements

A)  In Grade 9, 53 students liked burgers.

This is incorrect because 0.53 means 53% and need not equal to 53 students always.

B) In Grade 9, 73% of students liked noodles.

This is incorrect as from table we find that 27% of grade 9 liked noodles

C) In Grade 8, 40% of students liked noodles.

This is correct from the given table.

D)  In Grade 8, 10 students liked sandwiches

This is incorrect since number of students cannot be calculated from the relative frequency unless total students are given.

C) In Grade 8, 40% of students liked noodles.

step-by-step explanation:

if the four friends split the cost, p, of the pizza evenly, then each friend pays one-fourth of the cost of the pizza.

the expression is   or  

the answer is; biodiversity resulting from few ancestors

adaptive radiation occurs when a population is subjected to a large natural environment with spatial ecological variations. the parts of the population in the different ecologies begin to adapt to their local environments. due to non-random mating across the large populations, this causes the different populations from the large population to speciate within their local environments. they, therefore, diverge to different species sharing a common ancestor.
