Step-by-step explanation:
cards = 2
dollars = 9
to check that the number of cards with the correct amount d;
use the ratio and proportion.

Answer:
in standard form: 641000000
in scientific form: 6.41 * 10^8
Step-by-step explanation:
hi again :)
first, make each term into standard form: (6.7 * 10^8) = 670000000 and (2.9 * 10^7) = 29000000
670000000 - 29000000 = 641000000
in scientific notation: 641000000 = 6.41 * 10^8
hope this helps! <3

Answer:
Paired test
Step-by-step explanation:
The above research is carried out using a set of participants who were used to gather data under two different conditions. When this type of research is performed there is a match between the two conditions based on the subjects used, hence, we can pair the condition with the subject to obtain a matched pair. This sort of test also called the dependent sample t test. Thses type of test is ideal when the data is quantitative and the data obtained from two groups are dependent.
