Answer:

17 is a prime number.

Step-by-step explanation:

In each case, determine whether or not there is an integer that divides evenly into the given number:

9: we can divide this by 3 and 9, so 9 is NOT prime.

17: we can divide this only by 1. 17 is PRIME.

27: We can divide 27 by 3, 9 and 27; 27 is NOT prime.

33: We can divide 33 by 3 and 11. NOT prime.

The answer is 17 because all the others can be Times by more than one and itself

The distributive property can be applied to which expression to factor 12x3 – 9x2 + 4x – 3?

Arturiano [62]

Answer:

(4x - 3)(3x² + 1)

Step-by-step explanation:

Given

12x³ - 9x² + 4x - 3 ( factor the first/second and third/fourth terms )

= 3x²(4x - 3) + 1(4x - 3) ← factor out (4x - 3) from each term

= (4x - 3)(3x² + 1) ← in factored form

Cereal. A dietician obtains the amounts of sugar (incentigrams) from 100 centigrams (or 1 gram) in each of 10 differentcereals,

nadezda [96]

Answer:

Range is 44

mean is 29.7

variance is 289.56

standard deviation is 17.016

Step-by-step explanation:

The data given as follows

3, 24, 30, 47, 43, 7, 47,13, 44, 39

Range = maximum - minimum

= 47 -3 = 44

mean = $\frac{3+24+30+47+43+7+47+13+44+39}{10}$ = 297/10 = 29.7

variance = $\frac{sum xi^2 }{N} - mean^2 }$

= 289.56

SD = $\sqrt{variance}$ = 17.016

The standard deviation of the given data is not a good measure as the range and standard deviation are far apart. The standard deviation gives how the given data is dispersed from the mean or expected value, while the range gives a rough idea of variability of the data.
