A set of middle school student heights are normally distributed with a mean of 150 centimeters and a
standard deviation of 20 centimeters. Let X = the height of a randomly selected student from this set.
Find P(130 < x < 150).
You may round your answer to two decimal places.

Answers

Answer:

.34

Step-by-step explanation:

Khan

The required value of probability P(130< x < 150) is 0.34.

What is the Z -a score?

A Z-score is stated as the fractional model of data point to the mean using standard deviations.

here, z = x - μ / σ

where, μ = mean and σ = standard deviation

Here,
From the quesiton put value in z score formula,
z = 130 - 150 / 20
z = -1

P (z < - 1) = P(x<130) = 0.15866

P (x > 130) = 0.84134
Now,
P(130< x < 150) = 0.5 - P(x<130)
P(130< x < 150) = 0.5 - 0.15866 = 0.34134

Thus, the required value of P(130< x < 150) is 0.34.

Find how many years it takes for money to triple when invested at an annual interest rate of 4.3% compounded continuously. That’s the entire question and I’m not quite sure what to do?

Answers

9514 1404 393

Answer:

25.5 years

Step-by-step explanation:

The multiplier for continuous compounding at annual rate r for t years is ...

e^(rt)

You want the value of t when that is 3 and r=0.043.

3 = e^(0.043t)

ln(3) = 0.043t

t = ln(3)/0.043 ≈ 25.549 . . . . years

PLEASE HELP ASK

Answers

Answer:

8.12

Step-by-step explanation:

We obtain the distance between x and y

d = sqrt[(x2 - x1)² + (y2 - y1)²]

d = sqrt[(1 - 2)² + (2 - 6)²]

d = sqrt[1 + 16)

d = sqrt(17)

d² = 17

From Pythagoras rule;

Hypotenus = sqrt(Adjacent² + opposite²)

Hence,

Hypotenus = sqrt(17 + 7²)

Hypotenus = sqrt(17+ 49)

Hypotenus = sqrt(66)

Hypotenus = 8.124

Hypotenus = 8.12

Explanation:

The value of k determines the slope, or rate of change, of how fast the balloon is climbing per second.

For example, if k = 5, then that means the balloon is going upward at 5 feet per second (equivalent to roughly 3.41 mph)

If k = 5, then y = kt becomes y = 5t. Note how we have the following

t = 0 leads to y = 0t = 1 leads to y = 5t = 2 leads to y = 10t = 3 leads to y = 15

and so on. Each time t goes up by 1, d goes up by 5. This is one way to see how the speed is 5/1 = 5 ft per second.

Answers

Answer:

a. -21

b. -16

c. -11

d. -9

Step-by-step explanation:

if x is less than -2, then u have to use the equation 5(x)-1

if x is greater than or equal to -2, then you have to use the equation (x)-9

Answer:

Step-by-step explanation:

This is a ‘piece wise function’ meaning it has different functions depending on the value of the independent variable, x.

So for questions a and b where x<-2 you sub the x value into the top equation, 5x-1.

f(-4)=5(-4)-1=-20-1=-21

f(-3)=5(-3)-1=-15-1=-16

Since the second two x values are not less than -2, you sub the x values into the second equation x-9

f(-2)=-2-9=-11

f(0)=-0-9=-9
