Which steps show how to use the distributive property to evaluate 6 times 49

lina2011 [118]

Answer:

294

Step-by-step explanation:

The distributive property for multiplication is as follows :

a(b+c) = ab + ac

We need to evaluate 6 times 49 i.e. 6(49).

We can write 49 as (50-1)

6(50-1) = 6(50+(-1))

Here, a = 6, b = 50 and c = -1

So,

6(50+(-1)) = 6(50) + 6(-1)

= 300-6

= 294

So, answer is 294. Option (A) is somehow correct.

Answer:

Hence the correct option is option b) Yes, the upper level of one standard deviation is 72.

A score of 74 is not within one standard deviation of the mean.

Step-by-step explanation:

Here the given details are,

Mean = 68

SD = 4

Distribution is normal.

Z-score for x = 74 is given as below:

$Z = (X - mean)/SD\\Z = (74 - 68)/4\\Z = 1.5$

So, the score of 74 is 1.5 standard deviations from the mean.

$Mean + 1\timesSD = 68 + 1\times4 = 72Mean - 1\timesSD = 68 - 1\times4 = 64$

Therefore the score is not lies between 64 and 72.

Yes, the upper level of one standard deviation is 72.
