The exterior angles of a hexagon are 56º, 730, 2xº, 3x°, 4x° and 5xº.
Find the value of x.
Answer:
x = 16.5
Step-by-step explanation:
im assuming you meant 73 degrees instead of 730.
56+73 = 129
2x+3x+4x+5x = 14x
360-129 = 231
231 = 14x
231/14 = 16.5
x = 16.5

The diagram shows the cross-section ABCD of a sculpture in the shape of
a prism
with perpendicular height 9 cm.
AB = 14 cm, CD = 8cm, AD = 12cm and BC = 10cm
The height of the prism is also 9 cm.
What is the total surface area of the sculpture in cm2?
Type each step of your working on a separate line.
Answer:
99 (cm^2)
Step-by-step explanation:
Perpendicular to the AB segment at points D and C, the graph is divided into two triangles and a rectangle.
The area of the middle rectangle is equal to 8*9=72. The hypotenuse of the right triangle is 10cm, and one of the right sides is 9cm, so the other side is SQRT (10^2-9^2) = SQRT (19).
One side of the left triangle is 9cm long and the other side is 14-8-sqRT (19) = 6-sqRT (19) cm.
Then, add the area of the three parts.
72+9*sqrt(19)/2+9*(6-sqrt(19))/2=99 (cm^2)

What is linear equation ?A linear equation only has one or two variables. In a linear equation, no variable can be multiplied by a value greater than one or used as the denominator of a fraction. When you find the values that collectively make a linear equation true and plot those values on a coordinate grid, all the points fall on the same line.
I am aware that this query's equation is,
6b + 6 = 48
subtract 6 from both side in the equation.
6b + 6 - 6 = 48- 6
6b = 42
now, divide by 6 from both side in the equation.
6b/6 = 42/6
b = 7.

Factorise 3k+12 with explanation step by step
Answer:
3(k+4)
Step-by-step explanation:
3k and 12 have a common factor of 3
factor 3 out of the two values
3(k+4)
you can check by multiplying everything in the brackets by 3
3xk =3k
3x4=12
Answer:
3(k+4)
Step-by-step explanation:
As the common factor between 3k and 12 is 3.
so 3 goes infront of the open bracket. 3×K =3K and 3×4=12
so k+4 goes inside the brackets.

If P(B)=0.3,P(A∣B)=0.5,P(B ′ )=0.7, and P(A∣B ′ )=0.8, find P(B∣A).
If P(B)=0.3, P(A|B)=0.5, P(B')=0.7and P(A|B')=0.8, then the value of the probability P(B|A)= 0.2113
To find the value of P(B|A), follow these steps:
The probability of B given A can be given by the product of the probability of A given B and the probability of B, divided by the total probability of B. So, the formula for P(B|A) = P(A|B) * P(B) / [P(A|B)*P(B)+P(A|B')*P(B')]. Substituting the values, we get P(B|A) = (0.5) (0.3) / [(0.5) (0.3) + (0.8) (0.7)] ⇒P(B|A) = 0.15 / [0.15 + 0.56] ⇒P(B|A) = 0.15 / 0.71 ⇒P(B|A) = 0.2113. Therefore, P(B|A) = 0.2113.Learn more about probability:

a coin is tossed 20 times. a person who claims to have extrasensory perception is asked to predict the outcome of each flip in advance. she predicts correctly on 14 tosses. what is the probability of being correct 14 or more times by guessing? does this probability seem to verify her claim? use the normal distribution to approximate the desired probability.
The probability that she makes correct guesses 14 times or more is 0.0582 and this probability does not seem to verify her claim
Number of tosses of coin n = 20
probability she guesses correctly p = 0.5
Probability she guesses incorrectly q = 1- p = 0.5
P(X < A) = P( z*σ + μ < A) = P(z < (A-μ)/σ) (1) ( ∵ we know z = x - μ/σ)
Mean = μ = np = 20 * 0.5 = 10
Standard deviation = σ
Standard deviation σ = √npq = √(20 *0.5*(1-0.5) = √5 = 2.236
Probability of being correct 14 times or more
P(X ≥ 14) = 1 - P(X < 13.5)
= 1 - P(Z < (13.5 - 10)/2.236) (using 1)
= 1 - P(Z < 1.57)
= 1 - 0.9418
= 0.0582
Here, the probability of getting 14 or more is 0.0582 and it is usually as the probability is more than 0.05. Thus this probability does not verify her claim

claim: at most 28% of internet users pay bills online. A recent survey of 326 internet users indicated that 25% pay their bills online
bills refer to invoices or statements issued to request payment for goods or services provided. They typically outline the amount owed, due date, and payment instructions.
Based on the claim that at most 28% of internet users pay bills online, we need to determine if the recent survey supports or contradicts this claim.
The recent survey of 326 internet users indicated that 25% pay their bills online. To determine if this supports the claim, we need to compare the survey result to the claim.
Since the claim states "at most" 28% of internet users pay bills online, it means that 28% is the maximum percentage. Therefore, if the survey result of 25% falls within this range, it supports the claim.
To calculate this, we subtract the survey result (25%) from the maximum claim (28%):
28% - 25% = 3%
Since the difference is 3%, which is a positive value, the survey result of 25% falls within the maximum claim of 28%. Therefore, the recent survey supports the claim that at most 28% of internet users pay bills online.

find the cross product v = a ×b, where a = 〈1, 2, 3〉 and b = 〈3, 5, 8〉
The cross product of vectors a and b is v = 〈1, 1, -1〉.
The cross product of two vectors is a vector that is orthogonal (perpendicular) to both of the original vectors. It is calculated using the determinant of a 3x3 matrix.
Let's consider two vectors a = 〈a1, a2, a3〉 and b = 〈b1, b2, b3. To find the cross product of two vectors, we can use the formula:
v = (a2b3 - a3b2)i + (a3b1 - a1b3)j + (a1b2 - a2b1)k
Given vectors a = 〈1, 2, 3〉 and b = 〈3, 5, 8〉, we can substitute their components into the formula:
v = ((2 * 8) - (3 * 5))i + ((3 * 3) - (1 * 8))j + ((1 * 5) - (2 * 3))k
= (16 - 15)i + (9 - 8)j + (5 - 6)k
= 1i + 1j - 1k
= 〈1, 1, -1〉

if the population of 100 bacteria doubles every 15 min., how long will it take for population to reach 12,800 ?
Assuming that the bacteria population doubles every 15 minutes, it will take around 70.6 minutes for the population to increase from 100 to 12,800.
If the population of bacteria doubles every 15 minutes, it means that the growth rate is exponential. The initial population is 100, and we want to find the time it takes for the population to reach 12,800.
To solve this problem, we can use the exponential growth formula:
N(t) = N0 * 2⁽ᵗ/ᵀ⁾
where:
N0 = initial population (100 bacteria)
N(t) = population at time t
t = time elapsed
T = time it takes for the population to double (15 minutes)
We want to find the time it takes for the population to reach 12,800 bacteria, so we can set N(t) to 12,800:
12,800 = 100 * 2⁽ᵗ/¹⁵⁾
Dividing both sides by 100:
128 = 2⁽ᵗ/¹⁵⁾
Taking the logarithm (base 2) of both sides:
log2(128) = t/15
t = 15 * log2(128)
Using a calculator, we can solve for t:
t ≈ 70.6 minutes
Therefore, it will take approximately 70.6 minutes for the population of bacteria to reach 12,800, if the population doubles every 15 minutes.
