It takes 4 people 36 minutes to solve 18 problems. How many minutes will it take 6 people to solve 42 problems.

Step-by-step explanation:

slope in this case is 2/3

this equation is in slope intercept form

y=mx+b

m is slope

and b is y-intercept

so

m =2/3

b=-4

Answer: The slope is 2/3 (0.666...)

Step-by-step explanation: The slope is the coefficient of X in slope-intercept form. y=2/3x-4 is in slope-intercept form (y=mx+b) m = slope, b = y-intercept (the Y value when the X is equal to 0)

Answer:

a)[tex]1.3887943865 \times 10^{-11}[/tex]

b)P(X>5)=1

Step-by-step explanation:

[tex]P(X=x)=\frac{e^{-\lambda} \lambda^k}{k!}[/tex]

We are given that Messages arrive at a computer at an average rate of 25 messages per second.

[tex]\lambda = 25[/tex]

a) Find the probability that no message arrive in 1 second.

[tex]P(X=0)=\frac{e^{-25} (25)^0}{0!}\\P(X=0)=\frac{e^{-25} (25)^0}{0!}\\P(X=0)=1.3887943865 \times 10^{-11}[/tex]

b) Find the probability that more than 5 messages arrive in a 10-second period.

[tex]P(X>5)=1-P(X \leq 5)[/tex]

[tex]P(X>5)=1-\sum_{0}^{10} (P(X=0)+P(X=1)+........+P(X=5))[/tex]

P(X>5)=1

Answer: The maximum height of the ball was 2.5 seconds after it was thrown.

Step-by-step explanation:

As shown in the table, the ball started coming down after the third second and yet the height at both the second and third seconds were the same. This means that the ball hit its highest extent between the second and third seconds.

Taking an average of these digits will give;

= (2 + 3) / 2

= 2.5 seconds

The ball therefore hit its highest level at 2.5 seconds and then started its descent.

Step-by-step explanation:

When water is heated on a stove, thermal energy is transferred from the element to the water.

Energy is the quantitative property that is transferred to a body or to a physical system, recognizable in the performance of work and in the form of heat and light.

Given that When water is heated on a stove.

We need to find the type of energy is transferred from the element to the water.

Boiling water on a stove is an example of thermal energy.

Thermal energy refers to the energy contained within a system that is responsible for its temperature.

Heat is the flow of thermal energy.

Thermal energy is produced when the atoms and molecules in a substance vibrate faster due to a rise in temperature.

Hence, When water is heated on a stove, thermal energy is transferred from the element to the water.

Answer:

399/500

Step-by-step explanation:

the reason for this is because the area of the devision "1000 randomly selected flights of a major airline showed that 798 of the flights arrived on time" means that this is divided into places to make a full example

The probability of event of a flight arriving on time will be -

P(A) = 399/500.

Probability is the extent to which an event is likely to occur and is measured by the ratio of the favorable cases to the total number of cases possible.

Given is a study of 1000 randomly selected flights of a major airline which showed that 798 of the flights arrived on time.

Let event A represents the arrival of flight on time.

Total number of favorable cases = 798

Total number of possible cases = 1000

Then the probability of event A will be -

P(A) = 798/1000 = 399/500

Therefore, the probability of event of a flight arriving on time will be -

P(A) = 399/500

[tex]a=1[/tex]

[tex]b=-1[/tex]

Step-by-step explanation:

Once [tex](x-1)^2[/tex] is a factor and [tex](x-1)^2 = (x-1)(x-1)[/tex], we have that two roots of the cubic equation are equal to 1. So,

[tex]ax^3+bx^2+1 = (x-1)(x-1)(x-d)=0[/tex]

As [tex]d[/tex] the unknown root.

Expanding

[tex]ax^3+bx^2+1 = (x-1)(x-1)(x-d)=0[/tex]

[tex]ax^3+bx^2+1 = (x^2-2x+1)(x-d)=0[/tex]

[tex]ax^3+bx^2+1 = x^3-2x^2+x-dx^2+2dx-d=0[/tex]

Now, comparing the two expressions, we have

[tex]ax^3+bx^2+1 = x^3+(-2-d)x^2+(1+2d)x-d=0[/tex]

Therefore, know we know

[tex]a=1[/tex]

[tex]b=-2-d[/tex]

[tex]d=-1[/tex]

So,

[tex]b=-2-(-1)=-2+1=-1[/tex]

Step-by-step explanation:

The number of vacation days taken by employees of a company is normally distributed with a mean of 14 days and a standard deviation of 3 days. For the next employee, what is the probability that the number of days of vacation taken is less than 10 days? More than 21 days?

Answer: Z score is used in statistics to determine by how many standard deviations the raw score is above or below the mean. It is given by the equation:

[tex]z=\frac{x-\mu}{\sigma}\\ \\x=raw\ score,\mu=mean,\sigma=standard\ deviation[/tex]

Given that: μ = 14, σ = 3

a) For x < 10

[tex]z=\frac{x-\mu}{\sigma}\\ \\z=\frac{10-14}{3}=-1.33[/tex]

From the normal distribution table, P(x < 10) = P(z < -1.33) = 0.0918

b) For x > 21

[tex]z=\frac{x-\mu}{\sigma}\\ \\z=\frac{21-14}{3}=2.33[/tex]

From the normal distribution table, P(x > 21) = P(z > 2.33) = 1- P(z < 2.33) = 1 - 0.9901 = 0.0099

Answer:

Step-by-step explanation:

0.85 + 10

The function that Annie can use to calculate both price changes is f(p) = 1.85p+10. Therefore, option A is the correct answer.

Given that, a discount function on each price, d(p)=0.85p and then increase the resulting price is r(p)=p+10.

A discount is the reduction of either the monetary amount or a percentage of the normal selling price of a product or service.

Now, the function that Annie can use to calculate both price changes

f(p) = d(p)+r(p)

⇒ f(p) = 0.85p+(p+10)

⇒ f(p) = 1.85p+10

The function that Annie can use to calculate both price changes is f(p) = 1.85p+10. Therefore, option A is the correct answer.

Answer:

K = 2

Step-by-step explanation:

Simplifying

8(4k + -4) = -5k + 42

Reorder the terms:

8(-4 + 4k) = -5k + 42

(-4 * 8 + 4k * 8) = -5k + 42

(-32 + 32k) = -5k + 42

Reorder the terms:

-32 + 32k = 42 + -5k

Solving

-32 + 32k = 42 + -5k

Solving for variable 'k'.

Move all terms containing k to the left, all other terms to the right.

Add '5k' to each side of the equation.

-32 + 32k + 5k = 42 + -5k + 5k

Combine like terms: 32k + 5k = 37k

-32 + 37k = 42 + -5k + 5k

Combine like terms: -5k + 5k = 0

-32 + 37k = 42 + 0

-32 + 37k = 42

Add '32' to each side of the equation.

-32 + 32 + 37k = 42 + 32

Combine like terms: -32 + 32 = 0

0 + 37k = 42 + 32

37k = 42 + 32

Combine like terms: 42 + 32 = 74

37k = 74

Divide each side by '37'.

k = 2

Simplifying

k = 2
