Answer:

Step-by-step explanation:

Solve for the mean (average) of the five test scores.

Subtract that mean from each of the five original test scores. Square each of the differences.

Find the mean (average) of each of these differences you found in Step 2.

Take the square root of this final mean from #3. This is the standard deviation.

Maria bought a bag of flour so that she can make muffins it has a mass of 2.26 kg Shanice 450 g of flour to make one batch of mu
xenn [34]

Answer:

10 grams or 0.010kg

Step-by-step explanation:

The mass of the bag used to make flour is 2.26 kg = 2260 grams

Now, in order to find out how many badges she made, we would need to divide the weight of the bag by the amount needed to make a badge.

Therefore: \frac{2260}{450}  = 5.02

We know now that the bag will make 5 batches and will have some left over. In order to find how much we used, we can multiply 5 * 450 = 2250.

Therefore, in order to make 5 batches, Maria used exactly 2250 grams of flour which in result left us with 10 grams of the bag.

Note: 2260 -2250 = 10 grams.

Subtract, in order to find how many you have left.

Hope this helps.

Answer:

\frac{1}{2}  \: or \: 0.5

Step-by-step explanation:

\frac{5}{7}  \times  \frac{14}{20}  =  \frac{5 \times 14}{7 \times 20}

It can be also written as -

=  >  \frac{5 \times 14}{20 \times 7}  =  \frac{5}{20}  \times  \frac{14}{7}  =  \frac{1}{4}  \times 2 =  \frac{1}{2}
