What is the missing length in the right triangle?

Answers

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!

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?

Answers

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).

Answers

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.

Which functions are linear?
y=4/x
y=-4x + 1
y= 5(x – 0.6)

Answers

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.

Step-by-step explanation:

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.

Answers

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]

Imagine a swarm of jellyfish came at you. What would you do? Jellyfish are becoming a concern; they are swarming fishing nets and affecting power plant pipes. These fish have reduced the number of fish and are clogging power plant pipes. These fish pose a threat to our economy, what will we do about it? The jellyfish has ruined fish harvesting and drastically decreased fish numbers. The jellyfish have affected the fish population and ruined the power plants. The jellyfish sting and harm the fish, so they are swarming the fish away. The jellyfish continue to clog the pipes in the power plants, so they are forced to shut down the plant. The fish have caused many problems for fishers and for power plant workers. The fish are dangerous and are becoming the pests of the ocean. The solution to some of these problems are to use some extra precaution and smaller nets. These fish are a harmful and pesty problem for today's Economy. The workers should not be the people to worry about the jellyfish. The major solution to this problem is to cut down on pollution. The reason for this is so the jellyfish have nothing to feed on. The reason for these swarms and clogging is because the jellyfish feed on the trash and pollution. These fish are a threat to our economy and are a danger to humans and animals. The jellyfish solution should be started immediately. The jellyfish problem should be solved soon because if it doesnt the jellyfish will take over. The jellyfish could continue to harm the fish and clog the power plant pipes. The problem will continue if we dont do anything about it. Jellyfish are an example of the economy's many large problems, will this problem end the same? As Montag is reading to Mildred, he keeps thinking about Clarisse. Why does he do this?
