(3+√3) x (2+√2) gr 9 maths sum from number system ans fast pls

The model that you could use to find the probability is a binomial model with parameters n = 3, X = 3 and p = 0.45.

For each TV bought, there are only two possible outcomes, either it is wide screen, or it is not. The probability of a TV bought being wide screen is independent of any other TV, hence the binomial distribution is used to solve this question.

It is the probability of exactly x successes on n repeated trials, with p probability of a success on each trial.

Answer with step by step explanation

First, let us find the circumference of the small circle.

The radius of the small circle is 5 cm.

So, now let us see the formula which is needed to find the circumference.

C = 2 π r

Let us find it now.

Circumference of the small circle.

C = 2 π r

C = 2 × 3.14 × 5

C = 31.4 cm

  ≈ 30 cm → nearest 10th

Now let us find the circumference of the big circle.

The radius of the big circle is 10 cm.

C = 2 π r

C =  2 × 3.14 × 10

C = 62.8 cm

   ≈  60 cm → nearest 10th

Answer:

9 cm

Step-by-step explanation:

A= lw

54=6w

9=w

Answer:

9 cm

Step-by-step explanation:

⇒ Area of rectangle = (L)(B)

Substitute the length, breadth, and the area in the formula:

⇒ Area of rectangle = (L)(B) = 54 cm²

⇒ (6)(B) = 54 cm²

Divide 6 both sides:

⇒ (6)(B)/6 = 54/6 cm²

⇒ B = 9 cm

Thus, the measure of the width is 9 cm.

Using trigonometric ratio, the height of the ground above the ground to the nearest hundredth is 44.85 ft

The situation forms a right angle triangle.

Right angle triangle has one of its angles as 90 degrees. The sides and angles can be found using trigonometric ratios.

Therefore, the length of the string is the hypotenuse side of the triangle formed . The opposite side of the triangle is the height of the kite form the ground.

Therefore, the height of the kite form the ground can be found as follows;

sin 33° = opposite / hypotenuse

sin 33° = h / 75

cross multiply

h = 75 × sin 33

h = 40.8479276261

h = 40.84

The height of kite from ground = 40.847 + 3.5  = 44.3479276261 = 44.85 ft

Answer:

7.50 is the answer to the question

Answer:

$7.50 for 3 bottles of water.

Step-by-step explanation:

It is given that 4 bottles of water costs $10. Find the unit price per bottle of water, by simply dividing 4 from both the bottle of water as well as the cost:

(4 bottles of water/$10)/(4/4) = (1 bottles of water/(10/4)) = 1 bottles of water/2.5

Each bottle costs $2.50

Check. Multiply the unit price per amount of units bought:

2.50 x 4 = 10

Next, find the unit price for 3 bottles. Multiply the unit price with the amount of bottles bought:

$2.50 x 3 = $7.50

$7.50 is your answer.

Equation::

If words be x

Equation in slope intercept form

So

#1

More words=25-15=10

Cost:-

#2

Extra words=50-15=35

Cost:-

Answer:

a. $17.50

b. $31.25

Step-by-step explanation:

a.

For $12 you get 15 words.

For a 25-word ad, you need 10 more words than the 15 you get for $12, so you must add 10 words at $0.55 per word.

cost = $12 + 10 × $0.55

cost = $12 + $5.5

cost = $17.50

b.

50 words is 25 words more than 25 words, so you must pay for 25 words more than the cost of the 25-word ad in part a.

cost = $17.50 + 25 × $0.55

cost = $17.50 + $13.75

cost = $31.25

Answer:

100.5309649149

Step-by-step explanation:

circumference = 2π(r)

Since you already have the radius of the circle, you would have to multiply the radius by 2 to get the diameter which is the full width of the circle . Then, multiply the result by π, or 3.14 and then round how you are asked to.

Answer:

x = - [tex]\frac{3}{2}[/tex] , x = [tex]\frac{1}{2}[/tex]

Step-by-step explanation:

4x² + 4x = 3 ← factor out 4 from each term on the left side

4(x² + x) = 3

to complete the square

add/subtract ( half the coefficient of the x- term )² to x² + x

4(x² + 2([tex]\frac{1}{2}[/tex] )x + [tex]\frac{1}{4}[/tex] - [tex]\frac{1}{4}[/tex] ) = 3

4(x + [tex]\frac{1}{2}[/tex] )² - 1 = 3 ( add 1 to both sides )

4(x + [tex]\frac{1}{2}[/tex] )² = 4 ( divide both sides by 4 )

(x + [tex]\frac{1}{2}[/tex] )² = 1 ( take square root of both sides )

x + [tex]\frac{1}{2}[/tex] = ± 1 ( subtract [tex]\frac{1}{2}[/tex] from both sides )

x = - [tex]\frac{1}{2}[/tex] ± 1

then

x = - [tex]\frac{1}{2}[/tex] - 1 = - [tex]\frac{3}{2}[/tex]

x = - [tex]\frac{1}{2}[/tex] + 1 = [tex]\frac{1}{2}[/tex]

Ryan will have to make a monthly payment of $195.41

Answer:

3.

Step-by-step explanation:

remember, when we multiply the same basic term, we add the exponents.

so,

x⁴×x² = x⁶

now, when there are other factors, we need to multiply them in too.

so,

(6x⁴)(3x²) = 6×3×x⁴×x² = 18x⁶ or simply (6×3)x^(4+2)
