Answer:
The answer is B
Step-by-step explanation: After solving this equation using y=mx+b
I got y=-4x+7
So they give us the slope which is negative 4
so you would throw in the x coordinate with the slope and multiply to get y=-12+7
then you would use the y coordinate to substitute the Y
-5=-12+7
i add twelve on both sides and end up with the y intercept being 7]
so I add them into the equation and got y=-4x+7
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.
Step-by-step explanation:

For this parallelogram to exist least value of x should be 4.
Because if x = 3
(x - 3)= 3 - 3 =0
Thus width of parallelogram would become zero as a result area of parallelogram would become zero i. e. Parallelogram won't exist.
Answer:
The answer is the first one - 8 square roots of 3
Step-by-step explanation:
Using formula is sufficient here.
In hexagon there are 6 same triangles.
You calculate the area of one of them by formula (1/2)*(2)*(4square root of 3/3)
You multiply that by 6 and simplify.
The answer is the first one - 8 square roots of 3
