Amount of flour Helena accidentally poured =5\frac{1}{6} =\frac{31}{6} cups of flour.

Amount of flour the cake requires =3\frac{1}{2} =\frac{7}{2} cups of flour.

Amount of flour that Helena should take out =\frac{31}{6} - \frac{7}{2}

                                                                          =\frac{31}{6} - \frac{7 \times 3}{2\times 3}

                                                                          =\frac{31}{6} - \frac{21}{6}

                                                                          =\frac{31-21}{6}

                                                                          =\frac{10}{6}

                                                                          =\frac{5}{3}

                                                                          =1\frac{2}{3} cups of flour.

What is the remainder when (2x3 + x2 – 3x + 4) is divided by x – 2?
sergeinik [125]

Answer:

The remainder is  

−

7

Step-by-step explanation:

When  

P ( x ) = 2 x 3 – x 2 – 3 x + 7  is divided by  x + 2 ,we are dividing by  x −( − 2), so the remainder will be: P ( − 2 ) = 2 − 2 ) 3 –

Suppose you work in the quality assurance department of a chemical processing plant and it is your responsibility to ascertain w
aleksandrvk [35]

Answer:

48.668 ≤ μ ≤ 63.332

Step-by-step explanation:

Given the data:

Sample (X) : 71, 45, 54, 75, 50, 49, 63, 55, 48, 50

Number of samples (n) = 10

α = 95% = 0.05

Determine the range within which the true mean of the fluid samples from the day shift will be with a 95% confidence

True mean = μ

Confidence interval :

m ± t(α/2 ; df) * s/√n

m - t(α/2 ; df) * s/√n ≤ μ ≤ m + t(α/2 ; df) * s/√n

m = sample mean ; s = sample standard deviation ; df = degree of freedom =(n - 1) = (10 - 1) = 9

Calculating the sample mean and standard deviation using calculator to save computation time :

71, 45, 54, 75, 50, 49, 63, 55, 48, 50

m = 56 ; s = 10.25

m - t(0.05/2 ; 9) * s/√n ≤ μ ≤ m + t(0.05/2 ; df) * s/√n

From t table : t(0.05/2 ; 9) = t(0.025, 9) = 2.262

56-2.262 * (10.25/√10) ≤ μ ≤ 56+2.262 * (10.25/√10)

48.668 ≤ μ ≤ 63.332
