Answer:

Step-by-step explanation:

mean=(5.9+5.7+5.5+5.4+5.7+5.5+5.6+6.2+6.1+5.5)/10=57.1/10=5.71

we assume mean=5.7

x    mean  |x-mean| (x-mean)^2

5.9   5.7      0.2         0.04

5.7   5.7         0            0

5.5   5.7      0.2         0.04

5.4   5.7      0.3         0.09

5.7   5.7         0             0

5.5   5.7      0.2         0.04

5.6   5.7      0.1          0.01

6.2   5.7      0.5         0.25

6.1    5.7      0.4         0.16

5.5   5.7      0.2         0.04

                                --------

                                0.63

standard deviation=√((0.63)/10)=√(0.063)≈0.251

A baseball player has 39 hits in 134 times at bat. how many hits must he get in the next 46 times at bat to finish the year with
faust18 [17]

Answer:

He must get 33 hits in his next 46 times at bat to finish the year with a .400 batting average

Step-by-step explanation:

The player has already batted 134 times and will still bat 46 times. So in the end of the year, he is going to have 134 + 46 = 180 at bats.

How many hits does he need to have to hit .400?

This is 40% of 180, which is 0.4*180 = 72.

He has already 39 hits, so in his next 46 at bats, he will need 72 - 39 = 33 hits.

Colt1911 [192]

Answer:

<u>$3.90</u> was the cost of salami per kilogram.

Step-by-step explanation:

<u><em>The question is incomplete, so the complete question is below:</em></u>

Hailey\ paid\ \$13\ for\ 1\ 3/7\ kg\ of\ sliced\ salami.\ \\What\ was\ the\ cost\ per\ kilogram\ of\ salami?

Now, to find the cost of salami per kilogram.

Cost of 1\frac{3}{7} kilogram of sliced salami = $13.

Now, to get the cost of salami per kilogram we use unitary method:

If, the cost of \frac{10}{3} kilogram of salami = $13.

Then, the cost of 1 kilogram of salami = \frac{13}{\frac{10}{3}}

=\frac{13}{10}\times 3

=\frac{39}{10}

=\$3.90.

Therefore, $3.90 was the cost of salami per kilogram.

Describe how you regroup when you find the sum of 64+43
damaskus [11]
Here, regrouping is basically carrying. 

64+43 shown vertically would be:

  64
+43
-------
 107
4+3 is 7, so seven is in the ones place, but that's not the point.
60+40 is 100, so you regroup by carrying the one to the hundreds place.

Hope I helped!

New size of bread =  \frac{11}{5}\times 100=220 units

Percent of original size the new bread is
