Answer:
The number is -5
Step-by-step explanation:
Let x be the number
Write it out as an algebraic expression: 7x + 4 = -31Subtract 4 from each side, so it now looks like this: 7x = -35Divide each side by 7 to cancel out the 7 next to x. It should now look like this: x = -5I hope this helps!

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.

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.

Step-by-step explanation:
2(9n - 6) + 52 = 2(7n + 8)
Step-by-step explanation:
2×9n=18n
2×-6=-12
52-12+18n= 38 +18n
2×7n=14n
8×2=16
14n+16
38+18n=14n+16
subtract 14n from 14n and 18n
38+4n=16
subtract 38 from 38 and 16

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 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!
