Answer:

32

Step-by-step explanation:

p=sample proportion

p=number of defective parts/size of sample = 4/25

Estimate:

(sample proportion)x(size of population) = (4/25)x(200)=32

fish tested = 5x5=25

fish population = 40x5=200

Answer:

Answer:

[tex]V=3367.57\ cm^3[/tex]

Step-by-step explanation:

The diameter of a sphere, d = 18.6 cm

Radius, r = 9.3 cm

We need to find the volume of the sphere. The formula for the volume of a sphere is given by :

[tex]V=\dfrac{4}{3}\pi r^3\\\\=\dfrac{4}{3}\times 3.14\times (9.3)^3\\\\=3367.57\ cm^3[/tex]

So, the volume of the sphere is equal to [tex]3367.57\ cm^3[/tex].

Answer:

x = [tex]\frac{8\sqrt{3} }{3}[/tex]

Step-by-step explanation:

Using the sine ratio in the right triangle and the exact value

sin60° = [tex]\frac{\sqrt{3} }{2}[/tex]

sin60° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{4}{x}[/tex] = [tex]\frac{\sqrt{3} }{2}[/tex] ( cross- multiply )

x × [tex]\sqrt{3}[/tex] = 8 ( divide both sides by [tex]\sqrt{3}[/tex] )

x = [tex]\frac{8}{\sqrt{3} }[/tex] × [tex]\frac{\sqrt{3} }{\sqrt{3} }[/tex] ( rationalising the denominator )

x = [tex]\frac{8\sqrt{3} }{3}[/tex]

Answer:

120.105m^2

Step-by-step explanation:

Given data

Diameter of circular bed=  24+3m = 27m

radius= 27/2= 13.5 m

Diameter of side walk = 12

radius= 24= 12 m

Hence the area of the sidewalk is

Area= area of circular bed- area of side walk

Area=πR^2-πr^2

Area=π(R^2-r^2)

Area=π(13.5^2-12^2)

Area= 3.14(182.25-144)

Area= 3.14(38.25)

Area=120.105m^2

Hence the area of the side walk is 120.105m^2

Answer:

10x+14b+11

Step-by-step explanation:

3x+8b+7x+11+6b

3x+7x+8b+6b+11 = Regroup them

10x+14b+11 = Combine like terms

The requried, 3x+8b+7x+11+6b simplifies to 10x + 14b + 11.

Simplification involves applying rules of arithmetic and algebra to remove unnecessary terms, factors, or operations from an expression. The goal is to obtain an expression that is easier to work with, manipulate, or solve. For example, simplifying an algebraic expression might involve combining like terms, factoring, or using the distributive property

To combine like terms 3x+8b+7x+11+6b, we can add the coefficients of x, add the coefficients of b, and add the constant terms. So we have:

3x + 8b + 7x + 11 + 6b = (3x + 7x) + (8b + 6b) + 11

Combining the like terms:

= 10x + 14b + 11

Therefore, 3x+8b+7x+11+6b simplifies to 10x + 14b + 11.

Step-by-step explanation:

Answer:

8 and 5

Step-by-step explanation:

Answer:

Step-by-step explanation:

What are the factors of 40? 8 * 5

8 + 5 = 13

To do it algebraically gives you a quadratic:

A + B = 13

AB = 40

A(13 - A) = 40

A2 - 13A + 40 = 0

(A - 8)(A - 5) = 0

A = 8 and B = 5

Answer:

5333

Step-by-step explanation:

5000 x 0.10 = 500 a year

500 x 2/3= 333.33...

(as 8/12  =  2/3)

5000+ 333.33 = 5333 simplified

You cna also work out months this way

Explanation:

Add up the arc measures and divide by 2 to get the angle formed by the two chords.

angle AOB = (arc AB + arc CD)/2

angle AOB = (34 + 25)/2

Answer:

X < 7/2

Step-by-step explanation:

Move the variable to the left, separate into possible cases , solve, find the intersections, find the union, and then you get your solution.

Step-by-step explanation:

Given that:

|2x-7| = 7-2x

⇛2x-7 = 7-2x or -(7-2x)

since |x| = a ⇛ x = a or x = -a

⇛2x-7 = 7-2x or 2x-7 = 2x-7

Shift all variables on LHS and constant on RHS, changing it's sign.

⇛2x+2x = 7+7

Add the values on LHS and RHS.

⇛4x = 14

Shift the number 4 from LHS to RHS.

⇛x = 14/4

Write the fraction in lowest form by cancelling method.

⇛ x = {(14÷2)/(4÷2)}

⇛x = 7/2

There is no solution for negative value

x = 7/2
