Solution :
Let 
and 
represents the proportions of the seeds which germinate among the seeds planted in the soil containing 
and 
mushroom compost by weight respectively.
To test the null hypothesis 
against the alternate hypothesis 
.
Let 
denotes the respective sample proportions and the 
represents the sample size respectively.
The test statistic can be written as :
which under 
follows the standard normal distribution.
We reject at 
level of significance, if the P-value 
or if 
Now, the value of the test statistics = -1.368928
The critical value = 
P-value = 
= 0.171335
Since the p-value > 0.05 and 
, so we fail to reject at level of significance.
Hence we conclude that the two population proportion are not significantly different.
Conclusion :
There is not sufficient evidence to conclude that the 
of the seeds that 
with the percent of the 
in the soil.
Answer:
g=y-m/x
Step-by-step explanation:
You subtract m on both sides then you divide by x
It would look like
g=y-m/x
Answer:
36 = (x+7)^2 + (y-6)^2
Step-by-step explanation:
6^2=(x-(-7))^2 + (y-6)^2
Answer:
The correct option is (c).
Step-by-step explanation:
The given number is -0.904.
We need to represent the number in scientific notation.
Any number can be written in scientific notation as follows :
Where
a is a real number and b is an integer
We can write it as follows :
Hence, the correct option is (c).
Answer:
D
Step-by-step explanation:
a "function" gives every x value exactly one y value.
A, B and C all have 2 or more y values for an x value.
use e.g. a pen and place it vertically (straight top-down, parallel to the y-axis) on the graphs.
how often does the pen intersect the function curve ?
that is what I am talking about.
if it is more than once, than the x value (the point on the x-axis), where you put your pen, has more than 1 y values.
and that is then not a function.
only D is a function. the pen intersects with the function curve only once, no matter where you put the vertical pen.
