Given () = 2, = 1, and ∆ = 0.6:
Scorpion4ik [409]

Answer:

a)

\triangle y = 1.56

b) Dy=1.2

c) See attachment

Step-by-step explanation:

a)Let

\triangle x

be a small change in x, then the corresponding change in y is

\triangle y= f(x  +  \triangle x) - f(x)

We have

f(x) =  {x}^{2}

This implies that:

\triangle y= (x  +  \triangle x)^{2}  -  {x}^{2}

We substitute

x = 1 \: and \:  \:  \triangle x = 0.6

This gives

\triangle y= (1 + 0.6)^{2}  -  {1}^{2}  \\ \triangle y =  {1.6}^{2}  - 1 = 1.56

b) Let

y = f(x)

\frac{dy}{dx}  = f'(x)

This implies that:

dy = f'(x)dx

with dx=0.6 , and x=1,

dy = 2x dx

dy = 2(1)(0.6) = 1.2

What symbol is used for the arithmetic mean when it is a sample statistic? What symbol is used when the arithmetic mean is a pop
Andru [333]

Answer:

for sample = xbar

population = μ

Step-by-step explanation:

The arithmetic mean for sample can be represented by xbar and it can be calculated as

xbar=∑xi/n

Where xi represents data values and n represents number of data values in a sample.

The arithmetic mean for population can be represented by μ and it can be calculated as

μ=∑xi/N

Where xi represents data values and N represents number of data values in a population.

To make a specific shade of green paint, Timia mixes 2 cups of blue paint with 10 cups of yellow point. How many cups of yellow
7nadin3 [17]

Answer:

1 cup of blue paint required 5 cups of yellow paints

<em />

Step-by-step explanation:

Given

2 cups of blue = 10 cups of yellow

Required

Determine the number of cups of yellow for 1 cup of blue paint

The given parameter shows a linear relationship between paints of blue and paints of yellow

We have:

2 cups of blue = 10 cups of yellow

Multiply both sides by 0.5

0.5* 2 cups of blue = 0.5* 10 cups of yellow

1 cup of blue = 5 cups of yellow

Hence;

<em>1 cup of blue paint required 5 cups of yellow paints</em>
