Determine the remainder when (5x3 + 49x2 + 74x + 6) is divided by (x + 8).
blondinia [14]
The polynomial remainder theorem says that the remainder when dividing a polynomial P(x) by a linear divisor x-k is simply P(k).

If P(x)=5x^3+49x^2+74x+6, then the remainder upon dividing by x+8 is

P(-8)=-10

You could also verify this by actually computing the quotient and remainder.

The calibration of a scale is to be checked by weighing a 13 kg test specimen 25 times. Suppose that the results of different we
Natali5045456 [20]

Solution :

a).

Given : Number of times, n = 25

            Sigma, σ = 0.200 kg

            Weight, μ = 13 kg

Therefore the hypothesis should be tested are :

$H_0 : \mu = 13 $

$H_a : \mu \neq 13$

b). When the value of $\overline x = 12.84$

 Test statics :

   $Z=\frac{(\overline x - \mu)}{\frac{\sigma}{\sqrt n}} $

  $Z=\frac{(14.82-13)}{\frac{0.2}{\sqrt {25}}} $

          $=\frac{1.82}{0.04}$

          = 45.5  

P-value = 2 x P(Z > 45.5)

            = 2 x 1 -P (Z < 45.5) = 0

Reject the null hypothesis if P value  < α = 0.01 level of significance.

So reject the null hypothesis.

Therefore, we conclude that the true mean measured weight differs from 13 kg.

Does 32.60 round up or round down
adelina 88 [10]

That all depends what place you want it rounded to.

Rounding to the nearest tenth, it becomes  32.6 .
Rounding to the nearest whole number, it becomes,  33 .
Rounding to the nearest ten or higher order of magnitude, it becomes zero.
