Answer 1

Answer:

[tex]E(x) = 99[/tex]

Step-by-step explanation:

Given

The attached table

Required

Number of times 3 or 4 will occur

First, we complete the table as follows:

[tex]P(1) + P(2) +......+P(6) =1[/tex]

[tex]0.13 + 0.05 + P(3) + 0.21 + 0.19 + 0.3 = 1[/tex]

Collect Like Terms

[tex]P(3)= 1 -(0.13 + 0.05 + 0.21 + 0.19 + 0.3 )[/tex]

[tex]P(3)= 0.12[/tex]

The expected number of times is:

[tex]E(x)= n * P(x)[/tex]

So, we have:

[tex]E(x) = 300 * (0.12 + 0.21)[/tex]

[tex]E(x) = 300 * (0.33)[/tex]

[tex]E(x) = 99[/tex]

i need help with the volume, tsa and x please

Answers

Answer:

Volume = 42 units^2

x = 5 units

Total Surface Area = 96 units

Step-by-step explanation:

Volume

V = bh, where b = 1/2 * 3 * 4 and h = 7,

= 6 * 7 = 42 units^2

x

You can solve for this variable by using the pythagorean theorem;

a^2 + b^2 = c^2, where a = 3 and b = 4,

9 + 16 = x^2

= 25 = x^2

= x = 5 units

Total Surface Area

You can solve this by multiplying the perimeter of the base (3 + 4 + 5) by the height and adding that to two times the area of the base:

7 * (3 + 4 + 5) + 2(1/2*3*4)

= 7*12 + 12

= 96 units

A triangle has a base length of 14cm. The perpendicular height is 9cm. Find the area of the triangle

Answers

the answer is 42
14 x 9 / 3

The area of a triangle with the given base and height is 63 cm².

Given that, a triangle has a base length of 14 cm and the perpendicular height is 9 cm.

What is the area of a triangle?

The area of a triangle is defined as the total space occupied by the three sides of a triangle in a 2-dimensional plane. The basic formula for the area of a triangle is equal to half the product of its base and height, i.e., A = 1/2 × b × h.

Here, b=14 cm and h= 9 cm

So, area = 1/2 × 14 × 9

= 63 cm²

Therefore, the area of a triangle with the given base and height is 63 cm².

what is the perimeter of 6 and 2

Answers

Answer:

In order to calculate perimeter, you need to add together the lengths of all four sides of the square. You are given the length of one side. Remember, all sides of a square are equal, so really you already have the measures of each side. Then, you add them together, so 6 + 6 + 6 + 6 = 24 inches.

Step-by-step explanation:

To find the perimeter of a rectangle, add the lengths of the rectangle's four sides. If you have only the width and the height, then you can easily find all four sides (two sides are each equal to the height and the other two sides are equal to the width). Multiply both the height and width by two and add the results.

Estimate the volume of a soccer ball that has a diameter of 8 inches

Answers

Answer:

269 in³

Step-by-step explanation:

The formula for the volume of a sphere is V = (4/3)πr³.

Here the ball (sphere) diameter is 8 in, meaning that the radius is 4 in.

Thus, the volume of this ball is:

V = (4/3)π(4 in)³

If an "estimate" is good enough, use 3.14 for π:

V = (4/3)(3.14)(4 in)³  =  269 in³

Step-by-step explanation:

Answer:

b^8, with m = 8

Step-by-step explanation:

Apply the algebraic rule: (x^a)/(x^b) = x^(a-b)

Note: This rule is true because we can cancel all b factors that occur in both numerator and denominator.

From this rule, we know that (b^10)/(b^2) = b^(10-2)

b^(10-2) can be written b^8
