zysi [14]

Answer:

the answer is  

Step-by-step explanation:

The proportion of coconut milk in the cocktail is  ml for every 15 ml of orange juice.

Proportion shows the fractional composition of a given quantity or substance.

So that:

orange juice = 15 ml

contents of the orange juice;

apple juice = 25 ml

coconut milk = 10 ml

total              = 35 ml

So that;

the fraction of apple juice in the orange juice =  x 15

                                          =

the fraction of apple juice in the orange juice =  ml

Also,

the fraction of coconut juice in the orange juice =  x 15

                                        =

the fraction of coconut juice in the orange juice =  ml

Therefore, the proportion of the cocktail that is coconut milk is: for every 15 ml of orange juice, then  ml of coconut juice is required.

12.4. Measure of Dispersion<br>2076 Q.No. 15 Find the standard deviation of: 4, 6, 8, 10, 12.​
Alenkinab [10]

Answer:

Standard deviation of given data = 3.16227

Step-by-step explanation:

<u><em>Step(i)</em></u>:-

Given sample size 'n' = 5

Given data  4, 6,8,10,12

Mean = \frac{4+6+8+10+12}{5} = 8

Mean of the sample x⁻ = 8

Standard deviation of the sample

                  S.D = \sqrt{\frac{Sum(x-x^{-} )^{2} }{n-1}}

<u><em>Step(ii)</em></u>:-

Given data

x          :         4      6       8       10      12

x-x⁻      :      4 - 8   6-8   8-8    10-8    12-8

(x-x⁻)   :        -4      -2     0          2        4

(x-x⁻)²  :        16     4       0         4        16  

 

  S.D = \sqrt{\frac{Sum(x-x^{-} )^{2} }{n-1}}

  S.D = \sqrt{\frac{16+4+0+4+16}{4}}

 S.D = √10 = 3.16227

<u><em> Final answer</em></u>:-

The standard deviation = 3.16227

An experiment will be conducted in which 20 pepper plants are randomly assigned to two groups. The plants in Group 1 will receiv
Studentka2010 [4]

The experimental units in this experiment are the 10 plants in group 2.

The experimental unit is a term used in science to refer to an individual or group of objects that are initially equivalent and then undergo experimental processes.

According to the above, the experimental unit of this experiment is the group 2 of plants because these are the plants that are going to be put into experimentation with a new fertilizer.

Then, the answer is D, because it refers to the experimental unit corresponding to this experiment.
