Answer:

8

Step-by-step explanation:

You have to set up a proportion for this!

Because ABC and PAQ are similar triangles (same angles and PQ || BC), you can assume that all the equivalent sides are proportional!

If you solve the proportion for x:

\frac{x}{40} =\frac{7}{35}

x = 8

What does archieved mean if a question is archieved
VLD [36.1K]
It is the verb of storing information in a different place. For example, once I read an email, I will archive it, putting it in a folder to be deleted, but I can still view it if necessary. To archive a question would most likely mean to get rid of it.
I hope this helps.

Georgia [21]

Answer:

Option E

Step-by-step explanation:

Single-blinding refers to a kind of clinical trial in which only the researcher conducting the study knows which treatment or the participant is receiving until the trial is over.

Control Group refers to the group in an experiment that does not receive treatment by the researchers, it is used as a benchmark to measure how the other tested subjects do.

Under the random assignment, the study participants are randomly allocated to different groups, such as the experimental group, or treatment group.

Confounding can be controlled by adjusting for it after completion of a study using stratification or multivariate analysis.

The treatment group refers to the experimental groups that receive treatment in an experiment. The “group” is made up of test subjects (people, animals, plants, cells, etc.) and the “treatment” is the variable under study.

Since here we are making groups to perform the experiment away from the main workforce, the feature used here is the treatment group.

Answer:

The answer is in the explanation

Step-by-step explanation:

Mean value = \bar x = 438

(a) The data appeared to be centered towards 438.

There are little or no skew.

There is no outliers.

(b) yes

(c) standard deviation = s = 14.8955

95% confidence interval = +- t_{df}  * s\sqrt{n}

    438 +- 2.12 * 14.8955 /\sqrt{17}=

= (430.3415, 445.6585)

(d) Test statistic

t = (438 - 450)/{14.8955\sqrt17} }

t = -3.3216

p -value is correctly given in option b.

No, 450 is not a plausible valaue.
