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.

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]
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.

Which functions are linear?
y=4/x
y=-4x + 1
y= 5(x – 0.6)
Answer:
y=-4x + 1
y= 5(x – 0.6)
Step-by-step explanation:
y = -4x + 1 follows the linear equation of y = mx + b.
y = 5(x - 0.6) can be simplified into y = mx + b by distribution,
y = 5x - 3 which follows the linear equation of y = mx + b.
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!

What is the sum of the measures of the exterior angles of a polygon that has fifteen sides?
Answer:
The sum of the measures of the exterior angles of a polygon with 15 sides will be 360°.
Step-by-step explanation:
The Exterior Angle Sum Theorem defines that the sum of the exterior angles of any convex polygon is 360°.Given that a polygon has 15 sides.
If the polygon is regular with 15 sides, it indicates that each exterior angle is
360°/15 = 24°
so the measure of each exterior angle of a 15 sided polygon is 24°.As the polygon has 15 sides, the sum of the measures of the exterior angles of a polygon will be:
15 × 24 = 360°Therefore, the sum of the measures of the exterior angles of a polygon with 15 sides will be 360°.

Convert any mixed numbers to fractions.
Then your initial equation becomes:
15/4÷11/8
Applying the fractions formula for division,
=15×84×11
=12044
Simplifying 120/44, the answer is
= 2 8/11
When [tex]3\frac{3}{4}[/tex] is divided by [tex]1\frac{1}{8}[/tex] we get the fraction 10/3.
To divide mixed fractions, we first convert them to improper fractions, and then perform the division.
Let's convert the mixed fractions into improper fractions:
[tex]3\frac{3}{4}[/tex]= (4× 3 + 3) / 4 = 15/4
[tex]1\frac{1}{8}[/tex] = (8 × 1 + 1) / 8 = 9/8
Now, we can divide the fractions:
(15/4) / (9/8)
To divide fractions, we multiply the first fraction by the reciprocal of the second fraction:
(15/4) × (8/9)
30/9
The GCD of 30 and 9 is 3, so divide numerator and denominator by 3:
