Assume the random variable x is normally distributed with mean μ = 80 and standard deviation σ = 4. Find the indicated probability.
P(x < 72) = _____ (round to four decimal places as needed).
Answer:
0.2278
Step-by-step explanation:
z = (x-μ)/σ,
where x is the raw score
μ is the population mean
σ is the population standard deviation
z => 72 - 80/4
= -2
Probability value from Z-Table:
P(x ≤ 72) = P(x = 72) => P(x < 72)
0.02275
Approximately =>0.2278
The probability of the calculated value is " 0.0227501", its calculation can be defined as follows:
Normal distribution calculation:Mean [tex](\mu)= 80\\\\[/tex]
Standard Deviation [tex](\sigma)= 4[/tex]
Since we know that
[tex]\to Z_{\text{score}} =\frac{x-\mu}{\sigma} \\\\[/tex]
a)[tex]x = 72[/tex]
[tex]\to \frac{72-80}{4}=\frac{-8}{4}= -2[/tex]
so,
[tex]P(x < 72) = P(z < -2) =0.0227501[/tex]
PS: you have to refer z score table to find the final probabilities.

What is a linear system of equations?A system of linear equations consists of two or more equations made up of two or more variables such that all equations in the system are considered simultaneously. The solution to a system of linear equations in two variables is any ordered pair that satisfies each equation independently.
We know that, a nickel is worth 5 cents and a quarter is worth 25 cents.
Let the number nickels be x and the number of quarters be y.
Now, 0.05x+0.25y=8.80 ----------(I)
x+y=68 ----------(II)
Substitute x=68-y in equation (I), we get
0.05(68-y)+0.25y=8.80
⇒ 3.4-0.05y+0.25y=8.80
⇒ 0.20y=8.80-3.4
⇒ 0.20y=5.4
⇒ y=5.4/0.20
⇒ y=27
Substitute y=27 in equation (II), we get
x=41
Therefore, the number of nickels are 41 and the number of quarters are 27.

Peyton invested $690 in an account paying an interest rate of 5.6% compounded monthly. Assuming no deposits or withdrawals are made, how much money, to the nearest ten dollars, would be in the account after 8 years?
Answer:
$1,080.
Step-by-step explanation:
Given that Peyton invested $ 690 in an account with an annual interest of 5.6% compounded monthly, and that he kept said money in his account for 8 years without withdrawing or adding any amount, to obtain the final amount of money that said account would have after 8 years. years of investment, the following calculation must be made:
8 x 12 = 96
X = 690 x (1 + 0.56) 96
X = 1,078.85
Thus, after 8 years of investment, the amount that Peyton's account will have will be $ 1,078.85, that is, $1,080 rounded to the nearest ten dollars.

The lifetime of a computer can be modeled by an exponential random variable with an expected lifetime of 900 days. 1. Find the probability that the computer will function for more than 2000 days.2. Find the probability that the computer will function for more than 2000 days, given that it’s still working after 500 days.
Answer:
1. 0.108368
2. 0.188876
Step-by-step explanation:
Let X be the exponential random variable that represents the lifetime of a computer.
i.e. [tex]X\sim Exp(0.001)[/tex]
The probability that the computer will function more than 2000 days can be computed as follows:
P(X > 2000)
: [tex]f_X(x) = \lambda e^{-\lambda x[/tex]
P(X > 2000) = 1 - P(X< 2000)
P(X > 2000) = exp(-2000/β) = e⁻²²
P(X > 2000) = 0.108368
2.
By applying conditional probability;
[tex]P(X>2000 \bigg | X>500) =\dfrac{P(X>2000 \ \cap \ X>500)}{P(X> 500)}[/tex]
[tex]P(X>2000 \bigg | X>500) =\dfrac{P(X>2000 )}{P(X> 500)}[/tex]
[tex]P(X>2000 \bigg | X>500) =\dfrac{0.108368 }{0.57375}[/tex]
[tex]\mathbf{P(X>2000 \bigg | X>500) =0.188876}[/tex]

What is a number line?A number line is a visual representation of the set of real numbers. A number line is a straight line on which each point corresponds to a number. The points on the line are evenly spaced, with the distance between two points representing the difference between the numbers.
The question asks how many groups of 1/3 are in 4, which is equivalent to dividing 4 by 1/3, which can be expressed as 4 ÷ 1/3
To divide a number by a fraction, we can multiply the number by the reciprocal of the fraction.
The reciprocal of a fraction is obtained by flipping the numerator and denominator. The reciprocal of 1/3 is 3/1 which is 3. The expression can therefore, be expressed as follows;
4 ÷ (1/3) = 4 × 3 = 12
The quotient of 4 ÷ (1/3) is 12, which indicates that the number of groups of 1/3 in 4 are 12

What is the missing length in the right triangle?
Answer:
I would assume that s is also 5 because its an isosceles triangle. This leaves the hypotenuse side, which would be 7.07. To find a missing side when you have two sides, you can use the Pythagorean theorem, which is [tex]a^{2} +b^{2} = c^{2}[/tex]. The longest side will always represent c, so when you plug in a and b squared, you will get 50 in total. To get c by itself, you just need to square root it. I hope that made sense!
