−4x+14y=−16 x−72y=4

Mathematics
1 answer:
Goryan [66]3 years ago
4 0

Answer:

y = 0

x = 4

Step-by-step explanation:

Given that:

- 4x+14y=−16   ------------ eq1

   x−72y=4   -------------- eq2

Multiplying eq2 with 4 we get:

4x - 288y = 16 ---------- eq3

Now add eq1 and eq3 we get:

-58y = 0

By simplifying:

y = 0

Now put y=0 in eq2:

x - 72(0) = 4

x - 0 = 4

x = 4

So:

y = 0

x = 4

i hope it will help you!

Answer:

Randomized block design

Step-by-step explanation:

From the question, we can see the following:

- There are 30 plants of each variety. This means that they are divided into variety subgroups which we will call blocks.

- Now, we are told each plant in each block all are potted in the same amount and type of soil, given the same amount of water, and exposed to the same amount of light. This means that each plant in each block is assigned a treatment condition.

- The procedure is repeated by subjecting each plant one after the other in teach Block to different treatments and this will reduce variability.

Looking at all the statements above, it is clear that this is a randomized block design because a randomized block design is when the experimenter/researcher divides members/participants into subgroups called blocks in a manner that the variability within the blocks is less than the variability between the blocks. Thereafter, the participants within each block will now be randomly assigned to treatment conditions.

saveliy_v [14]

Answer:

Yes

Step-by-step explanation:

Given that in the June 2007 issue, Consumer Reports also examined the relative merits of top-loading and front-loading washing machines, testing samples of several different brands of each type.

The difference in mean values test gave a p value of 0.32

Confidence level = 95%

Alpha = 1-0.95 = 0.05

Compare p with alpha, here p >alpha

Hence we accept null hypothesis that there is no difference in the means.

Confidence interval method also will yield the same result.  i.e. confidence interval for difference of means would definitely contain 0 at 95% conf level.

So answer is yes
