Step-by-step explanation:

Answer:

12 inches

Step-by-step explanation:

1. The diagonal is the hypotenuse of the right triangle.  so since we know one side length, we can figure out the other side length

Step-by-step explanation:

area of rec= length×width

=10×4

= 40

radius= diameter/2

=4/2 = 2

area of semicircle= πr²/2

=22/7×2×2×1/2

=6.28

=6.3

adding both

we get,

=40+6.3

= 46.3

Answer:

2/20

Step-by-step explanation:

x/2 = 1/10

multiply both sides by 2

x = 2/20

Answer:

[tex]\frac{x^2+2x}{x-3}[/tex]

Step-by-step explanation:

We need to factor out numerator and denominator in order to simplify the rational expression by cancelling  common factors.

Numerator :  x^3 - 4 x = x (x^2 - 4) = x (x - 2) (x + 2)

Denominator (factoring by grouping):

x^2 - 5 x + 6 = x^2 - 3 x - 2 x + 6 = x (x - 3) - 2 (x - 3) = (x - 3) (x - 2)

Then we can cancel out the common factor (x - 2) in both numerator and denominator, leading to:

x (x + 2) / (x - 3) = (x^2 + 2)/ (x-3)

Answer:

3, 2, 0

Step-by-step explanation:

trust me

The resultant value of vectors are:

1. z + w = -1 + 3i.

2. w - u= -4 - 4i

3. u + w = -4.

Given:

z = 2 + 5i

w = -3 - 2i

u = -1 + 2i

1. z + w:

Adding the real and imaginary parts separately gives

(2 + 5i) + (-3 - 2i) = (2 - 3) + (5 - 2)i

                          = -1 + 3i

Therefore, z + w is equal to -1 + 3i.

2. w - u:

Subtracting the real and imaginary parts separately gives

(-3 - 2i) - (-1 + 2i) = (-3 + 1) + (-2 - 2)i

                          = -4 - 4i

Therefore, w - u is equal to -4 - 4i.

3. u + w:

Adding the real and imaginary parts separately gives

(-1 + 2i) + (-3 - 2i) = (-1 - 3) + (2 - 2)i

                           = -4

Therefore, u + w is equal to -4.

Step-by-step explanation:

Answer:

Surface area = 207 cm²

Step-by-step explanation:

Surface are of triangular prism = 2×BA + P × H

Base Area (BA) = ½*bh

b = 8 cm

h = 9 cm

BA = ½*8*9 = 36 cm²

Perimeter of triangular base (P) = 8 + 9 + 10 = 27 cm

Height for prism (H) = 5 cm

Surface area = 2 × 36 + 27 × 5 = 72 + 135

Surface area = 207 cm²

Answer:

X=14

Step-by-step explanation:

Answer:

47.5

Step-by-step explanation:

you would do 5 x 9.5 to find the answer for x

Answer:

a)

The possible values are 0, 1, 2 and 3.

The probability mass function of X is:

P(X = 0) = 0.125

P(X = 1) = 0.375

P(X = 2) = 0.375

P(X = 3) = 0.125

b)

[tex]P(X \geq 1) = 0.875[/tex], [tex]P(X > 1) = 0.5[/tex]

c) E(X) = 1.5, Var(X) = 0.75

Step-by-step explanation:

For it time the coin is flipped, there are only two possible outcomes. Either it comes up heads, or it comes up tails. Each toss is independent of other tosses. So we use the binomial probability distribution to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

And p is the probability of X happening.

The expected value of the binomial distribution is:

[tex]E(X) = np[/tex]

The variance of the binomial distribution is:

[tex]V(X) = np(1-p)[/tex]

A fair coin is flipped three times.

This means that [tex]n = 3[/tex]

Fair coin means that it is equally as likely to be heads or tails, so [tex]p = \frac{1}{2} = 0.5[/tex]

a) Give both the possible values and probability mass function of X.

The possible values are from 0 to n, so 0, 1, 2 and 3.

The probability mass function is the probability of each outcome. So

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 0) = C_{3,0}.(0.5)^{0}.(0.5)^{3} = 0.125[/tex]

[tex]P(X = 1) = C_{3,1}.(0.5)^{1}.(0.5)^{2} = 0.375[/tex]

[tex]P(X = 2) = C_{3,2}.(0.5)^{2}.(0.5)^{1} = 0.375[/tex]

[tex]P(X = 3) = C_{3,0}.(0.5)^{3}.(0.5)^{0} = 0.125[/tex]

(b) Find P(X ≥ 1) and P(X > 1).

[tex]P(X \geq 1) = P(X = 1) + P(X = 2) + P(X = 3) = 0.375 + 0.375 + 0.125 = 0.875[/tex]

[tex]P(X > 1) = P(X = 2) + P(X = 3) = 0.375 + 0.125 = 0.5[/tex]

(c) Compute E[X] and Var(X).

[tex]E(X) = np = 3*0.5 = 1.5[/tex]

[tex]Var(X) = np(1-p) = 3*0.5*0.5 = 0.75[/tex]

The expressions are equivalent to the perimeter of the shape is c. 4x + 4

The perimeter of a form is the space surrounding its edge. Find the perimeter of various forms by summing the lengths of their sides.

Perimeter of the rectangle = 2(length+width)

Given the paramters are;

length  = x + 1

W = x + 1

Perimeter of the shape= x+1+1+x+x+1+x+1

Perimeter = x+1+1+x+x+1+x+1

= 4x + 4

This is the expression equivalent to the perimeter of the shape

The answer is c.
