The sum of the polynomials x^2 + 9 and -3x^2 - 11x^4 - 4 is - 11x^4  -2x^2 + 5

<h3>How to determine the sum?</h3>

The polynomials are given as:

x^2 + 9

-3x^2 - 11x^4 - 4

The sum is represented as:

x^2 + 9 -3x^2 - 11x^4 - 4

Collect like terms

- 11x^4  -3x^2 + x^2 + 9 - 4

Evaluate the sum

- 11x^4  -2x^2 + 5

Hence, the sum of the polynomials is - 11x^4  -2x^2 + 5

Fifteen years from now Ravi's age will be four times his present age.What is Ravi's present age ? Frame the equation and solve.
Archy [21]

Answer:

Ravi's age after 15 years = x+15

Ravi's age = 4 times his present age = 4x

According to question -

15 + x = 4x

=> 15 = 4x-x = 3x

=> 15 = 3x

=> x = 15/3

=> x = 5

Thus , Ravi's present age is 5 years.

Based on data collected 5 years ago, a hotel expects that 24% of all guests will request smoking rooms. The hotel suspects that
9966 [12]

Answer:

The calculated value Z = 2.3084 > 1.96 at 5% level of significance

Null hypothesis is rejected

Alternative hypothesis is accepted

The hotel does not expects that 24% of all guests will request smoking rooms

Step-by-step explanation:

<u><em>Step(i):</em></u>-

Given the hotel takes a random sample of 223 guests. Out of this sample, 39 guests requested smoking rooms.

Sample proportion

                          p = x/n = 39/223 = 0.174

Given Population proportion 'P' = 0.24

Given random sample size 'n' = 223

Level of significance ∝ =0.05

The critical value Z₀.₀₅ = 1.96

<u><em>Null Hypothesis</em></u> (H₀) : P=0.24

<u><em>Alternative Hypothesis</em></u> (H₁) : P≠ 0.24

<u><em>Step(ii)</em></u>:-

<em>Test statistic </em>

            Z = \frac{p-P}{\sqrt{\frac{PQ}{n} } }

           Z = \frac{0.174-0.24}{\sqrt{\frac{0.24 X 0.76}{223} } }

           |Z| = | -2.3084|= 2.3084

The calculated value Z = 2.3084 > 1.96 at 5% level of significance

Null hypothesis is rejected

Alternative hypothesis is accepted

The hotel does not expects that 24% of all guests will request smoking rooms
