9
Step-by-step explanation:
75 percent of 12 is 9 I don't know what else to type here sorry
To answer the problem above, we first need to know the difference in hours.
from month 1 to 2 the difference in hour is 1.5.
Month 2 to 3 = 3.5 to 5 = 1.5
Month 3 to 4 = 5 to 6.5 = 1.5
Month 4 to 5 = 6.5 to 8 = 1.5
The answer is C. Linearly, because the table shows that hours increase by an equal factor for an equal increase in months. which is 1.5 hours per month.
Let "x" represent the number of units
5x = the number of tomato plants in Inessa's garden
6x = the number of tomato plants in Ralph's garden
the question says that half (1/2 x (5x)) of Inessa's tomato plants are taken from her garden and put into Ralph's garden
this means that Ralph has a total of 850 tomato plants in his garden
using all of this information, we get the following (which we have to solve):
(1/2)(5x) + 6x = 850
when we solve for "x", we find that:
"x" = 100
so, going back to the original statement, if Ralph started out with (6x) tomato plants, and "x" = 100, we have to multiply 6 by 100
doing so gives us our final answer:
Ralph had 600 tomato plants in the beginning
Answer:
Option d
Step-by-step explanation:
Given that television networks frequently run public opinion polls on issues of concern. One network conducted a scientific poll asking a question concerning the approval rating of the way President Obama was handling the Iraq War. At about the same time a second network ran an online poll using a very similar question.
Observed data is
Poll Scien Online total
approve 339 385 724
disapprove 780 573 1363
1119 958 2087
(Two tailed chi square test)
Let us find out expected and chi square
Expected = row total x column total/grand total
The cell count expected in the online poll for those who approve
=
chi square = 7.81
Hence option d is right.
