Find the slope of the line that passes through 10, -8 1,12

In a NiCd battery, a fully charged cell is composed of Nickelic Hydroxide. Nickel is an element that has multiple oxidation stat

Westkost [7]

Answer:

P(cell has at least one of the positive nickel-charged options) = 0.83.

P(a cell is not composed of a positive nickel charge greater than +3) = 0.85.

Step-by-step explanation:

It is given that the Nickel Charge Proportions found in the battery are:

0 ==> 0.17

.

+2 ==> 0.35

.

+3 ==> 0.33

.

+4 ==> 0.15.

The numbers associated to the charge are actually the probabilities of the charges because nickel is an element that has multiple oxidation states that is usually found in the above mentioned states.

a) P(cell has at least one of the positive nickel-charged options) = P(a cell has +2 nickel-charged options) + P(a cell has +3 nickel-charged options) + P(a cell has +4 nickel-charged options) = 0.35 + 0.33 + 0.15 = 0.83.

Or:

P(a cell has at least one of the positive nickel-charged options) = 1 - P(a cell has 0 nickel-charged options) = 1 - 0.17 = 0.83.

b) P(a cell is not composed of a positive nickel charge greater than +3) = 1 - P(a cell is composed of a positive nickel charge greater than +3)

= 1 - P(a cell has +4 nickel-charged options) '.' because +4 is only positive nickel charge greater than +3

= 1 - 0.15

= 0.85

To summarize:

P(cell has at least one of the positive nickel-charged options) = 0.83!!!

P(a cell is not composed of a positive nickel charge greater than +3) = 0.85!!!

Click an item in the list or group of pictures at the bottom of the problem and, holding the button down, drag it into the corre

Irina18 [472]

Well if the perimeter is 36in, then divide by 6 sides (the prefix hex- means six) to get 6. Don't forget your unit of measurement to be 6in of each side. It would be nice to have the picture though so if you could suply me with that it would help out.

The following probability distributions of job satisfaction scores for a sample of information

kodGreya [7K]

Answer:

a. 4.05 b. 3.84 c. 1.2475 and 1.1344 d. 1.1169 and 1.0651 e. We can say that the overall job satistaction of senior executives and middle managers is about 4; however, there is more variability in the job satisfaction for senior executives than in the job satisfaction for middle managers.

Step-by-step explanation:

a. (1)(0.05)+(2)(0.09)+(3)(0.03)+(4)(0.42)+(5)(0.41) = 4.05

b. (1)(0.04)+(2)(0.1)+(3)(0.12)+(4)(0.46)+(5)(0.28) = 3.84

c. We compute the variances as follow: $[(1)^2(0.05)+(2)^2(0.09)+(3)^2(0.03)+(4)^2(0.42)+(5)^2(0.41)] - 4.05^2$ = 1.2475 and $[(1)^2(0.04)+(2)^2(0.1)+(3)^2(0.12)+(4)^2(0.46)+(5)^2(0.28)]-3.84^2$ = 1.1344

d. The standard deviation is the squared root of the variance, therefore, we have $\sqrt{1.2475} = 1.1169$ and $\sqrt{1.1344} = 1.0651$

e. The expected value of the job satisfaction score for senior executives is very similar to the job satisfaction score for middle managers. We can say that the overall job satistaction of senior executives and middle managers is about 4; however, there is more variability in the job satisfaction for senior executives than in the job satisfaction for middle managers.

WILL MARK BRAINLIEST PLEASE HELP ME

Answer:

4 blue marbles

Skills needed: Number Theory, Fractions

Step-by-step explanation:

1) The problem tells us that the jar contains marbles that are either red, green, or blue (No Other Color).

It also mentions that $\frac{2}{5} (\frac{4}{10})$ of the marbles are red

and that $\frac{1}{10}$ of the marbles are blue

- The given statement is that 20 marbles are green, and we need to find out the number of blue marbles.

2) We need to first find out the total number of marbles, and then multiply that by $\frac{1}{10}$ to get the # of blue marbles.

---> Given $\frac{4}{10}$ are red and $\frac{1}{10}$ are blue, $1-\frac{1}{10}-\frac{4}{10}$ of the marbles are green (since fractions add up to 1 whole)
