Rounded to the nearest tenth is 585.1

Answer:

585.1

Step-by-step explanation:

To round this number; 585.055 to the nearest tenth, you need to first know the place value of each of the number and then the rules of rounding off.

Place value is just the value represented by the digit in a number because of its position in that number.

In the digit; 585.055

Moving from left to right, the first 5 stands for five hundred

8 stands for eight tens

The second 5 stands for five ones or five  units

0 stands for zero tenth

the first 5 stands for five hundredths

the second 5 stands for five thousands.

Now we move ahead to state the rules of rounding off.

In our case, we are to round to the nearest tenth, since 0 is in the tenth position, 0 is our target number, Now the immediate number after the target number is called the decider. All numbers before the target number are written back the way the are ( that is we are going to re-write 585 without altering anything)

The decider will tell if we are going to re-write our target number the way it is or if we are going to increase it by one. If the decider is from 5 and  above, we will increase our target number by 1, but if the decider is from 4 downward, we are going to re-write our target number down without altering anything.  ( In this case, 5 is our decider, so  we will increase zero by 1)

When you are rounding a decimal number, both the decider and every other number after the decider will not be written back again.

So from the above explanation ,  585.055  can be rounded up to 585.1 to the nearest tenth

I don’t know how to do it can someone help me?

Answer:f(g(0))= 1/5

              g(f(0))= 7

Step-by-step explanation:

for f(g(0))=you solve for g(x) but you plug in 0 for x so g(0)= 8(0)+3

                                                                                                    =3

 so now you plug in the answer of the function of g(x) witch is 3 and plug it in as the x for F(x) so f(3)= 1/(3)+2

                                     = 1/5

so f(g(0)) is equal to 1/5

Now for G(f(0)) you solve for f(x) by pluging 0 for x so F(0)= 1/(0)+2

                                                                                               =1/2

now you plug in 1/2 for the x of g(x) so g(1/2)= 8(1/2)+3

                                                                         = 4+3

                                                                         =7

so g(f(0)) is equal to 7

Hope this helps:)

A food company sells salmon to various customers. The mean weight of the salmon is 37 lb with a standard deviation of 2 lbs. The
brilliants [131]

Answer:

The standard deviation for the mean weigth of Salmon is 2/3 lbs for restaurants, 2/7 lbs for grocery stores and 1/4 lbs for discount order stores.

Step-by-step explanation:

The mean sample of the sum of n random variables is

\overline{X} = \frac{X_1+X_2+...+X_n}{n}

If X_1, ..., X_n are indentically distributed and independent, like in the situation of the problem, then the variance of X_1 + .... + X_n will be the sum of the variances, in other words, it will be n times the variance of X_1 .

However if we multiply this mean by 1/n (in other words, divide by n), then we have to divide the variance by 1/n², thus \overkine{X} = \frac{V(X_1)}{n} and as a result, the standard deviation of \overline{X} is the standard deviation of X_1 divided by \sqrt{n} .

Since the standard deviation of the weigth of a Salmon is 2 lbs, then the standard deviations for the mean weigth will be:

  • Restaurants: We have boxes with 9 salmon each, so it will be \frac{2}{\sqrt{9}} = \frac{2}{3}
  • Grocery stores: Each carton has 49 salmon, thus the standard deviation is \frac{2}{\sqrt{49}} = \frac{2}{7}
  • Discount outlet stores: Each pallet has 64 salmon, as a result, the standard deviation is \frac{2}{\sqrt{64}} = \frac{1}{4}

We conclude that de standard deivation of the mean weigth of salmon of the types of shipment given is: 2/3 lbs for restaurants, 2/7 lbs for grocery stores and 1/4 lbs for discount outlet stores.
