Answer:

Step-by-step explanation:

Red Graph: y = x^3 + 16x^2 + 81x + 126

Blue Graph: y = x^3 + 2x^2 - x - 2

Green Graph: y = -x^3 + 15x^2 - 74x + 120

Choose the right graph by factoring out the equations and finding the zeros

Red graph:

(x + 3)(x + 6)(x + 7) x ≠ -3, -6, -7

Blue graph:

(x + 2)(x + 1)(x - 1) x ≠ -2, -1, 1

Green graph:

(-x + 4) (x - 5) (x - 6) x ≠ 4, 5, 6

Add or subtract the polynomials

Mashcka [7]

Answer:

7xy + 6y + 6xy is a polynomial who’s like terms are 7xy and 6xy. Therefore, this polynomial can be simplified by combining like terms as 7xy +6xy +6y = 13xy + y. When combining like terms, we only add or subtract the coefficients of the identical variables.

On the other hand, unlike terms are terms which are not identical in terms of either variables or exponents.

For example, an expression 4x + 9y2, contain unlike terms because variable x and y are different and are not raised to the same power.

Delta makes 12-volt car batteries. These batteries are known to be normally

blondinia [14]

Answer:

The probability that Delta car batteries last between three and four years

P(36≤X≤48) = 0.5188

The percentage of that Delta car batteries last between three and four years

P(3≤X≤4) = 52%

Step-by-step explanation:

Step(i):-

Given that the sample size n =12 -volt car batteries

Let 'X' be a Random variable in a normal distribution

Given that mean of the normal distribution = 45 months

Given that the Standard deviation of the normal distribution = 8months

Step(ii):-

Let X₁ = 3 years = 12 × 3 = 36 months

$Z_{1} = \frac{x_{1} -mean}{S.D} = \frac{36-45}{8} = -1.125$

Let X₂ = 4 years = 12 × 4 = 48 months

$Z_{2} = \frac{x_{2} -mean}{S.D} = \frac{48-45}{8} = 0.375$

Step(iii):-

The probability that Delta car batteries last between three and four years

P(36≤X≤48) = P(-1.125≤Z≤0.375)

= P(Z≤0.375) - P(Z≤-1.125)

= 0.5 +A(0.375) - (0.5-A(1.125)

= 0.5 + 0.1480 - (0.5 -0.3708)

= 0.1480 + 0.3708

= 0.5188

Final answer:-

The probability that Delta car batteries last between three and four years

P(36≤X≤48) = 0.5188

The percentage of that Delta car batteries last between three and four years

P(3≤X≤4) = 52%
