The absolute value of 4 by 3 would be 3.33

What is the absolute value?

The absolute value or modulus of a real number x denoted |x| in mathematics, is the non-negative value of x regardless of its sign.

We have to find the absolute value of 4/3.

So |4/3| = |3.33|

             = 3.33

Hence, the absolute value of 4 by 3 would be 3.33

Typing errors in a text are either nonword errors (as when "the" is typed as "teh") or word errors that result in a real but inc
nordsb [41]

Answer:

a) X is binomial with n = 10 and p = 0.3

Y is binomial with n = 10 and p = 0.7

b) The mean number of errors caught is 7.

The mean number of errors missed is 3.

c) The standard deviation of the number of errors caught is 1.4491.

The standard deviation of the number of errors missed is 1.4491.

Step-by-step explanation:

For each typing error, there are only two possible outcomes. Either it is caught, or it is not. The probability of a typing error being caught is independent of other errors. So we use the binomial probability distribution to solve this question.

Binomial probability distribution

Probability of exactly x sucesses on n repeated trials, with p probability.

The expected value of the binomial distribution is:

E(X) = np

The standard deviation of the binomial distribution is:

\sqrt{V(X)} = \sqrt{np(1-p)}

10 word errors.

This means that n = 10

(a) If X is the number of word errors missed, what is the distribution of X ?

Human proofreaders catch 70 % of word errors. This means that they miss 30% of errors.

So for X, p = 0.3.

The answer is:

X is binomial with n = 10 and p = 0.3.

If Y is the number of word errors caught, what is the distribution of Y ?

Human proofreaders catch 70 % of word errors.

So for Y, p = 0.7.

The answer is:

Y is binomial with n = 10 and p = 0.7

(b) What is the mean number of errors caught?

E(Y) = np = 10*0.7 = 7

The mean number of errors caught is 7.

What is the mean number of errors missed?

E(X) = np = 10*0.3 = 3

The mean number of errors missed is 3.

(c) What is the standard deviation of the number of errors caught?

\sqrt{V(Y)} = \sqrt{np(1-p)} = \sqrt{10*0.7*0.3} = 1.4491

The standard deviation of the number of errors caught is 1.4491.

What is the standard deviation of the number of errors missed?

\sqrt{V(X)} = \sqrt{np(1-p)} = \sqrt{10*0.3*0.7} = 1.4491

The standard deviation of the number of errors missed is 1.4491.

Jeremy wants to buy a new parka that cost $ 14.80 plus play tax of 5% he has saved $8.41. how much more does he need to save
kramer
14.80+5%=15.54 and to get to that answer we have to add 8.41 and 7.13 and you will get 15.54.

Find the surface area
Sergio [31]

Answer:

174.7

Step-by-step explanation:

Let's find the area of the two triangles

(2)(1/2)(11*7.7) = 84.7

Back rectangle

3 x 11 = 33

Front facing rectangle

3 x 9 = 27

Bottom rectangle

3 x 10 = 30

Total = 84.7 + 33 + 27 + 30 = 330 + 60 + 30 = 420

If my answer is incorrect, pls correct me!

If you like my answer and explanation, mark me as brainliest!
