Work out the weekly mean number of 50 kg bags of flour used in these 5 weeks

bogdanovich [222]

Answer:

Weekly Mean Number of 50-kg bags =10.8 bags

Step-by-step explanation:

In Week 1, Kim uses 7 50kg bags of flour

In Week 2, Kim uses 14 50kg bags of flour

In Week 3, Kim uses 8 X 50kg bags of flour

In Week 4, Kim uses 13 X 50kg bags of flour

In Week 5, Kim will make 2400 loaves.

Each of these loaves will need 250g of flour.

Total Mass of flour that will be used =2400 X 250=600,000 grams

$600,000$ grams=600,000 \div 1000$ kg =600kg\\Number of 50-kg bags =600 \div$ 50 =12 bags$

In Week 5, Kim will use 12 bags.

Therefore:

Weekly Mean number of 50kg bags of flour used in these 5 weeks.

$=\dfrac{7+14+8+13+12}{5}\\\\ =\dfrac{54}{5}\\\\=10.8 \\ \approx 11$ bags$

Which equations and/or functions represent the graphed line? Select three options.

Reil [10]

Answer:

$y=\frac{1}{2}x+2$

Step-by-step explanation:

Let's take points (2,3) and (-4,0)

Slope

$m=\frac{y_2-y_1}{x_2-x_1}\\\Rightarrow m=\frac{0-3}{-4-2}\\\Rightarrow m=\frac{3}{6}\\\Rightarrow m=\frac{1}{2}$

So,

$y=mx+c\\\Rightarrow y=\frac{1}{2}x+c$

To find c we put value of (2,3) in the equation

$3=\frac{1}{2}2+c\\\Rightarrow 3-1=c\\\Rightarrow 2=c$

Equation of line

$y=\frac{1}{2}x+2$

a study of nickels showed that the standard deviation of the weight of nickels is 300 milligrams. A coin counter manufacture wis

cupoosta [38]

Using the z-distribution, a sample of 609 nickels has to be weighed.

<h3>What is a z-distribution confidence interval?</h3>

The confidence interval is:

$\overline{x} \pm z\frac{\sigma}{\sqrt{n}}$

The margin of error is:

$M = z\frac{\sigma}{\sqrt{n}}$

In which:

$\overline{x}$ is the sample mean.

z is the critical value.

n is the sample size.

$\sigma$ is the standard deviation for the population.

For this problem, the parameters are:

$M = 20, \sigma = 300, z = 1.645$

We solve for n to find the sample size, then:

$M = z\frac{\sigma}{\sqrt{n}}$

$20 = 1.645\frac{300}{\sqrt{n}}$

$20\sqrt{n} = 1.645 \times 300$

$\sqrt{n} = 1.645 \times 15$

$(\sqrt{n})^2 = (1.645 \times 15)^2$

n = 608.9

Rounding up, a sample of 609 nickels has to be weighed.
