Jobisdone [24]3 years ago
4 0

Answer:

You'll need to post the polynomial itself. The degree will be the highest exponent, the leading coefficient will be the number in front of the variable of the term with the highest exponent, then count the number of terms separated by + and - signs.

Step-by-step explanation:

igomit [66]

Answer:

Probability that the proportion in our sample of red candies will be less than 20% is 0.5 .

Step-by-step explanation:

We are given that 20% of the candy produced are red. A random sample of 100 bags of Skittles is taken.

The distribution we can use here is;

               \frac{\hat p - p}{\sqrt{\frac{\hat p (1- \hat p)}{n} } } ~ N(0,1)

where, p = 0.20 and n = 100

Let \hat p = proportion of red candies in our sample

So, P(\hat p < 0.20) = P(\frac{\hat p - p}{\sqrt{\frac{\hat p (1- \hat p)}{n} } } < \frac{0.20 - 0.20}{\sqrt{\frac{0.2 (1- 0.2)}{100} } } ) = P(Z < 0) = 0.5

Therefore, probability that the proportion in our sample of red candies will be less than 20% is 0.5 .

Factor this trinomial completely. -12x^2+45x+12
Amanda [17]

Step-by-step Answer:

Step 1:

Extract factor(s) common to all terms.

In this case, the HCF is 3, so the expression is written

-12x^2+45x+12 = -3(4x^2-15x-4)

The negative sign was also exrracted to give a positive leading coefficient, which is easier to work with.

Step 2, group the coefficient in such a way that there is a common factor.

Leaving the factor -4 for the moment, and concentrate on the coefficients in parentheses, write the original expression as

4x^2 - 15x -4  

= 4x^2 -16x

          +   x -4

= 4x*(x-4) + 1*(x-4)

extract (x-4) as a common factor

= (x-4)(4x+1)

Step 3:

Combine all the factors to get

-3(x-4)(4x+1)

=3(4-x)(4x+1)

as the complete factoring of the given expression.
