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:

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 input is the number you feed into the expression

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!

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

4n=-22

Answer: the Ferris Wheel

Step-by-step explanation:

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.

Answer:

$1,080.

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]

The number of nickels are 41 and the number of quarters are 27.

Given that, Angela has a collection of nickels and quarters worth $8.80.

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.
