Find the area of the shaded portion below.

Answer:

2.345×0.023

2.345..........3 decimal point

0.023........3 decimal point

    2345

×       23               1.    first we change it whole number for multiply.

····················          2.count the decimal point.here  6 decimal points are there.

+ 7 0 3  5          3.we got the answer 53935.here only 5 digits are there.

4 6 9 0 0         4.now we add one zero backside  053935

····························5 . final answer is   0.053935

 5  3  9  3   5

Answer:

The Salesperson age after performing each of the correlation and regression analyses in the prior questions shows that:

Even if a correlation is substantial, you don't know for sure until you measure it in a regression model with several other relevant variables.

Step-by-step explanation:

The simple difference between correlation and causation is that a correlation measures the linear relationship between two variables, while causation is a statistical measure that establishes that one event or variable is the cause of another event or variable.  With correlation established, one needs to study the strength of the relationship through a regression analysis before concluding on how one variable affects another variable.

Answer:

2x + 21

Step-by-step explanation:

Given :

Plant 1 : production level) 5x + 17

Plant 2 : production level = 3x - 4

To how much more plant 1 produces than plant 2 ; subtract production of plant 2 from plant 1

(5x + 17) - (3x - 4)

Open the bracket

5x + 17 - 3x + 4

5x - 3x + 17 + 4

2x + 21

Answer:

£9.80

Step-by-step explanation:

The computation of the total value is shown below:

Given that

The value of 20p coins is £2.80

So the value of 50p would be

= £2.80 × 50 ÷ 20

= £7

Now the total value is

= £2.80 +  £7

= £9.80

Answer:

Proved

Step-by-step explanation:

The options are not given. So, I will solve from scratch

Given

[tex]\frac{secx-1}{tan x}= \frac{tanx}{secx+1}[/tex]

Required

Prove

Multiply the right-hand side by [tex]\frac{secx + 1}{secx + 1}[/tex]

[tex]\frac{secx-1}{tan x} * \frac{secx + 1}{secx + 1}= \frac{tanx}{secx+1}[/tex]

Apply difference of two squares on the numerator

[tex]\frac{sec^2 x - 1}{(tanx)(secx + 1)} =\frac{tanx}{secx+1}[/tex]

In trigonometry:

[tex]tan^2x = sec^2x - 1[/tex]

So, we have:

[tex]\frac{tan^2 x}{(tanx)(secx + 1)} =\frac{tanx}{secx+1}[/tex]

[tex]\frac{tan x * tan x}{(tanx)(secx + 1)} =\frac{tanx}{secx+1}[/tex]

tan x cancels out

[tex]\frac{tan x}{secx + 1} =\frac{tanx}{secx+1}[/tex]

Answer:

80in²

Step-by-step explanation:

Hey There!

So the first step of this problem is to find the width of the scale drawing

To do so we need to find the scale factor

To find the scale factor we divide the length of the room by the length of the scale factor

32/8=4

so the scale factor is 4

now to find the width

40/4=10

so the width of the scale drawing is 10 in

now we can find the area given the length and the width

10x8=80in²

so we can conclude that the area of the scale drawing is 80in²

Answer:

Approximately [tex]5.7[/tex] inches

Step-by-step explanation:

The crossbar and two given lengths form a right triangle. We know this because we see a right angle marked on the diagram in between the two given sides.

In this case, we have a right triangle with legs of [tex]4[/tex] and [tex]4[/tex], and we need to find the hypotenuse. By the Pythagorean Theorem ([tex]a^{2} +b^{2} =c^{2}[/tex], where [tex]a[/tex] and [tex]b[/tex] are the legs and [tex]c[/tex] is the hypotenuse), we get:

[tex]4^{2} +4^{2} =c^{2}[/tex]

[tex]16+16=c^{2}[/tex] (Evaluate exponents)

[tex]32=c^{2}[/tex] (Combine like terms)

[tex]\sqrt{32}=\sqrt{c^{2}}[/tex] (Take the square root of both sides of the equation to get rid of [tex]c[/tex]'s exponent)

[tex]c=4\sqrt{2} ,c=-4\sqrt{2}[/tex]

The latter solution is an extraneous solution because the side lengths of a triangle cannot be negative. Therefore, the answer is [tex]4\sqrt{2} \approx 5.7[/tex] inches. Hope this helps!

Answer: Charity is 36 years old today.

Step-by-step explanation:

Let x = Present age of daughter.

Age of Charity = 4x

Age of her husband = 4x+6

After 10 years,

Age of daughter = x+10

Age of Charity = 4x+10

Age of her husband = 4x+6+10=4x+16

As per given,

[tex]x+10+4x+10+4x+16=117[/tex]

[tex]9x+36=117\\\\ 9x=117-36\\\\ 9x=81\\\\ x=9[/tex]

Present age of Charity = 4(9)=36 years

Hence, Charity is 36 years old today.

3/5(30) = 90/5 = 18

Answer:

Step-by-step explanation:

The chart tells you Zack has 30 stamps in total.

3/5 are animal stamps.

So you do

30 x 3/5 = 90 / 5 = 18

OR

30 / 5 x 3 = 6 x 3 = 18
