let x be a normally distributed random variable with mean 5 and standard deviation 15. please express your answer as a number between 0 and 100. if you want to write 52%, please enter 52. what is the probability that x is less than or equal to 38?

Answer:

y=1/2x+2

Step-by-step explanation:

y=mx+b

m = slope = rise/run

b = y-intercept

Look at the graph, and find the slope.

m= slope = rise/run = 1/2

b = y-intercept = 2

Therefore, the correct answer is option y=1/2x+2

The exit mass flow rate times the exit velocity less the free stream mass flow rate times the free stream velocity equals the force (thrust).

If we take into account the factors mentioned above, we will see that if the aircraft can fly at full thrust in cruise, this fits nicely with a static sea level thrust force equivalent to one third of its weight force. The thrust required to sustain flight is approximately 1/18 of the aircraft weight. It takes classroom teaching, ground training, and flying training from a certified instructor to obtain a high-altitude endorsement. we will learn about the warning signs and symptoms of altitude sickness, when to use supplemental oxygen, how long you can use that oxygen safely, and more during ground school.

he wants to give each of his 6 children the same number of bills.

how many bills can he give each child?

how many bills will Hong have remaining?

since Hong has 16 one dollar bills and he wants 6 children the same number of bills

then he give 6 children two bills to each  

then the total number of bills he give to 6 children is 12

and he has 16 bills and 12 bills give to his children

the remaining bills left = 16 bills - 12 bills = 4 bills

You would expect 4.5 diodes to fail. The standard deviation of the number that are expected to fail is 2.089.

The number of diodes failing, E(X), can be calculated by multiplying the population, n, with the probability, p.

n = 150

p = 0.03

E(X) = n × p

E(X) = 150(0.03)

E(X) = 4.5

Standard deviation, denoted by σ, is defined as the measure that indicates the average distance of observations from the mean of the data set.

σ = √(n x p x (1 - p))

σ = √(150 x 0.03 x (1 - 0.03))

σ = √150 x 0.03 x 0.97

σ = √4.365

Answer:

d. It is the same distance from zero as the number she tells you.

Step-by-step explanation:

Case 1: Let Shanika thought a positive rational

number

Let the number that Shanika thought be c.

Then, the distance of it from zero = lc - Ol = c.

But, the number she told = -c

The distance of -c from zero = 10--(-c)| = c

Case 2: Let Shanika thought a negative rational number

Let the number that Shanika thought be -c (c>0).

Then, the distance of it from zero = 10--(-c)| = c.

But, the number she told = c

The distance of -c from zero = Ic-01 = c

In both cases, the number she thought is the same distance from zero as the number she tells us.

Answer: M + 7

The total profit made by the company over the course of its first 24 years of operation is $10,016,640

Given,

The annual profit made by a company in first year = $111,000

The increase in profit per year = 24% = $26640

We have to find the total profit made by the company over the course of its first 24 years of operation

Lets take this as an arithmetic progression.

First term, a = 111,000

Common difference, d = 26640

nth term = 24

Sum of nth term,

Sₙ = n/2 [2a + (n - 1) d]

S₂₄ = 24/2 [2 × 111,000 + (24 -1) 26640]

S₂₄ = 12 [222,000 + 23 × 26640]

The length of the arc intercepted by a central angle of

6 radians is 60.34 cm.

An arc is any smooth curve joining two points.

Given is an circle of radius 10 cm intercepted by a central angle of

6 radians.

We can calculate the length of the arc using the formula -

L[arc] = (Ф/360°) x 2πr

Ф = 6 radians = 343.78 degrees

L[arc] = (343.78/360) x 2π x 10

L[arc] = 0.96 x 2π x 10

L[arc] = 60.34 cm

Step-by-step explanation:

the easy straight forward method is to simply sum up the 5 terms.

you know that this symbol just means "sum", right ?

and that the index variable is "running" from 1 to 5.

so, you have to sum up

3×1 + 3×2 + 3×3 + 3×4 + 3×5 = 3 + 6 + 9 + 12 + 15 = 45

now, if you want it done via a summary formula to add the first n terms of an arithmetic sequence, like in this case

a1 = 3

an = an-1 + 3 = a1×n = 3n

then

the sum of the first n terms in an arithmetic sequence is (n/2)⋅(a₁+aₙ).

it simply means : first plus last term added up n/2 times.

why ?

because a1 + an = a2 + an-1 = a3 + an-2 = ...

we get n/2 times such part sums.

so, in our case, n = 5, and we get

(3 + 3×5)×5/2 = (3 + 15)×5/2 = 18×5/2 = 9×5 = 45

Answer:

∑ (i = 1 to 5) (3·i)

Therefore, the table follows a linear pattern.

Hence, using (0, -2)(1, 5) we can find the slope and the y-intercept of the linear function.

Therefore,

m = 5 - (-2) / 1 - 0

m = 5 + 2 / 1

m = 7

Two decimals are 0.34, 0.83, and 0.83 and Holland could have used it to make a sum of 2.

A number system is defined as a way to represent numbers on the number line using a set of symbols and approaches. These symbols, which are known as digits, are numbered 0 through 9. Based on the basic value of its digits, different types of number systems exist.

We get x + x = 2x by using x to signify our missing values and the assumption that there are two missing values. We obtain the equation 2x + 0.34 since it is the product of these integers and 0.34; after setting it equal to 2, 2x + 0.34 equals 2.

First, take 0.34 off both sides to get 2x = 1.66. To get x = 0.83, divide both sides by 2 now.
