Answer:

Option A

Step-by-step explanation:

Given data

We are told that the weight of the rabbit is 2.8 kilograms

We also want to convert from kilograms to grams

We  know that 1kg= 1000 grams

            Hence 2.8 kg= x gram

Cross multiply

x= 2.8*1000

x= 2800 grams

Hence the weight in grams is 2800grams

Option A is correct

You are working in a small, student-run company that sends out merchandise with university branding to alumni around the world.
topjm [15]

Answer:

The answer is "0.142466".

Step-by-step explanation:

Using the p formula for the proportion of nonconforming units through the subgrouping which can vary in sizes:

p =\frac{np}{n}\\\\

\bar{p}=\frac{\Sigma np}{\Sigma n}\\\\

Defects = \frac{5}{100} \times 50 \\\\

p = \frac{5}{100} \times \frac{50}{50}=0.05\\\\

It calculates the controls limits through the p-chart that is:

UCL_{p},LCL_{p}=\bar{p} \pm \sqrt{\frac{\bar{p}(1-\bar{p})}{\bar{n}}}\\\\

So, the upper control limits:

= 0.05 + 3 \times \sqrt{(\frac{0.05\times(1-0.05)}{50})} \\\\= 0.142466

Determine the constant of proportionality,k,of Kevin’s wage.
ankoles [38]

Answer:

Kevin's constant of proportionality,k = $8.25 per hour

Greg's constant of proportionality,k = $9 per hour

Savannah's constant of proportionality,k = $9.5 per hour

Step-by-step explanation:

1. What is the constant of proportionality, k, of Kevin's wage? Greg's? Savannah's?

Solution

y = kx is a proportional variation

Where,

y and x are represent two different variables

k represent constant of proportionality

From the attached table,

Let

y = wages earned (in dollars)

x = hours worked

To find the constant of proportionality k of Kevin's wage, divide the variable y (total earned) by the variable x (number of hours)

Using any points on the table

Take (8,66.00) for example

constant of proportionality k of Kevin's wage = variable y (total earned) / variable x (number of hours)

= 66.00/8

= 8.25

k = $8.25 per hour

B. Constant of proportionality of Greg's wage = variable y (total earned) / variable x (number of hours)

Using (9, 81.00)

k = 81.00/9

= 9

Greg's k = $9 per hour

C. Constant if proportionality of Savannah's wage = variable y (total earned) / variable x (number of hours)

Using (6, 57.00)

k = 57.00/6

= 9.5

Savannah's k = $9.5 per hour

Therefore,

Kevin's constant of proportionality,k = $8.25 per hour

Greg's constant of proportionality,k = $9 per hour

Savannah's constant of proportionality,k = $9.5 per hour

What is the length of HG?
Leviafan [203]

Answer:

HG = 5

Step-by-step explanation:

Given

HE = 8mm

EF = 12mm

Area = 68mm^2

Find the length of HG

First, it should be noted that the displayed figure is a trapezium

<em>The area of a trapezium is calculated by multiplying the sum of parallel sides by half its height;</em>

In this case;

Area = \frac{HG + EF}{2} * HE

Substitute the values of Area, HE and EF

68 = \frac{HG + 12}{2} * 8

68 = (HG + 12) * 4

Divide both sides by 4

\frac{68}{4} = \frac{(HG + 12) * 4}{4}

17 = HG + 12

Subtract 12 from both sides

17 - 12 = HG + 12 - 12

5 = HG

HG = 5

<em>Hence, the length of HG is 5mm</em>
