What is the equation of the line?

Answers

Answer:

A) y=(4)/(7)x

Step-by-step explanation:

The line passes through the origin, so its y-intercept is (0,0). Therefore, we can eliminate choices B and C since they have a y-intercept ≠ 0.

Also recall that the rate of change in a linear function is defined by the change in y divided by the change in x, or the rise/run. We see there's a rise of 4 and a run of 7. Therefore, the slope of the line is 4/7, making choice A correct.

Geophysicists determine the age of a zircon by counting the number ofuranium fission tracks on a polished surface. A particular zircon is of such anage that the average number of tracks per square centimeter is five. What is the probability that a 2cm^2 sample of this zircon will reveal at most three tracks,thus leading to an underestimation of the age of the material?

Answers

Answer:

0.0108

Step-by-step explanation:

Let X denote the number of uranium fission tracks occurring on the average 5 per square centimetre.We need to find the probability that a 2cm² sample of this zircon will reveal at most three tracks. X follows Poisson distribution, λ = 5 and s = 2.

k = λs = 5×2 = 10

Since we need to reveal at most three tracks the required probability is:

P (X≤3) = P (X =0) + P (X =1) + P (X =2) + P (X =3)

P (X≤3)  = (((e^​-10) × (10)⁰)/0!) +  (((e^​-10) × (10)¹)/1! +  (((e^​-10) × (10)²)/2! + (((e^​-10) × (10)3)/3!

P (X≤3)  = 0.0004 + 0.0005 +0.0023 +0.0076

P (X≤3)  = 0.0108

Therefore, the probability that a 2cm² sample of this zircon will reveal at most three tracks is 0.0108

Answer:

p(x = 3, λ = 5) = 0.14044

Step-by-step explanation:

Given

λ = 5 (the average number of tracks per square centimeter)

ε = 2.718 (constant value)

x = 3 (the variable that denotes the number of successes that we want to occur)

p(x,λ) = probability of x successes, when the average number of occurrences of them is λ

We can use the equation

p(x,λ) = λˣ*ε∧(-λ)/x!

⇒ p(x = 3, λ = 5) = (5)³*(2.718)⁻⁵/3!

p(x = 3, λ = 5) = 0.14044

a jeepney ride in the sinakos 9 pesos for the first 4 kilometers and each additional km at 0.75 pesos to the fair use a piecewise function to represent the jeepney fare in terms of the distance in kilometers​

Answers

Answer: f(x) = 9 pesos if  0km ≤ x ≤ 4km

f(x) = 9 pesos + (x - 4km)*0.75 pesos if  4km ≤ x

Step-by-step explanation:

Ok, we know that:

For the first 4km, we have a fixed price of 9 pesos.

For any km after the 4km mark, we have an extra of 0.75 pesos.

Then if x is the number of kilometers, we can write this as:

f(x) = 9 pesos if  0km ≤ x ≤ 4km

f(x) = 9 pesos + (x - 4km)*0.75 pesos if  4km ≤ x

Where we use (x  - 4km) because we start counting after the 4km mark.

−1, 0

Answers

Answer:

-2, 2

Step-by-step explanation:

The pair of numbers that sum = 0 is:

-2,2

-2 + 2 = 0

Final answer:

In this Mathematics question, the given pairs of numbers were added individually to find the pair that sums up to 0. The pair that sums to 0 is -2 and 2.

Explanation:

In the field of Mathematics, the sum of two numbers is the result when those numbers are added together. In this particular question, you are given four options and need to find out which pair of numbers would add to give the sum of 0. The pairs and their sums are:

  • -1 + 2 = 1
  • -2 + 0 = -2
  • -2 + 2 = 0
  • -1 + 0 = -1

Therefore, the pair of numbers that has a sum of 0 is -2 and 2.

How does logical operator work- explain the differences between A AND B and A OR B? (6 pts)

Answers

Answer with Step-by-step explanation:

We are given two input A and B

A AND B=A\cdot B

If A=0 and B=0 then A\cdot B=0

If A=0 and B=1 then A\cdot B=0

If A =1 and B=0 then A\cdot B=0

If A=1 and B=1 then A\cdot B=1

A OR B=A+B

If A=0 and B=0 then A+B=0+0=0

If A=0 and B=1 then A+B=0+1=1

If A =1 and B=0 then A+B=1+0=1

If A=1 and B=1 then A+B=1+1=1

If A=0 and B=1 or A=1 and B=0 then A AND B=0 but A OR B=1

This is the main difference A AND B and A OR B.
