Use the given values of n an p to find the minimum usual value mean - 2standard deviations and the maximum usual value. N= 1056,

SCORPION-xisa [38]

Answer:

The minimum usual value: 818.803

The maximum usual value: 870.797

The population mean: 844.8

The standard deviation: 12.9985

Step-by-step explanation:

The parameters provided for the Binomial Distribution are:

n=1056, p=0.80

The population mean can be computed as:

μ = n ⋅ p

= 1056 × 0.80 = 844.8

The population variance is obtained by:

σ² = n ⋅ p ⋅ (1 − p)

= 1056 × 0.80 × 0.2 = 168.96

The standard deviation can be computed by taking the squared root of the variance:

σ = $\sqrt{n.p.(1-p)}$

= $\sqrt{168.96}$

= 12.9985

The minimum usual value: μ - 2σ = 844.8 - 2(12.9985)

= 844.8 - 25.997

= 818.803

The maximum usual value: μ + 2σ = 844.8 + 2(12.9985)

= 844.8 + 25.997

= 870.797

Solve each equations for x. How are these equations similar?

Artyom0805 [142]

If you multiply a. by x it is equivalent to b.
So both are x= z/(w+x)

Give the formula for a function with domain (5, ∞) that has the following properties:

KATRIN_1 [288]

Answer:

The area under the curve y = f(x) at x-axis, on the interval x E (5, ∞) is equal to 7.

Step-by-step explanation:

Solution

Given that:

f(x) = 7√x-5

The function of domain is:

D = x-5 > 0

x>5

so,

x← (5, ∞)

Now,

(1) The sequence root function is always known as positive, i.p defined from x E (5, ∞)

i.p =√x-5

Thus,

7/√x-5 >0

Therefore f(x) = 7/√√x-5 which is a positive integer, which is defined in domain x E (5, ∞).

Each value exist a real and unique values of f(x)

Now,

The function f(x) is continuous and over the interval(5, ∞)

What are two decimals equivalent to 0.20?

Rzqust [24]

Answer:

2/10 and 1/5

Step-by-step explanation:

1/5 because i simplified 2/10 factor of 2

2/10 is the decimal form of 0.2 or 0.20

Elliot borrows $900 to buy an appliance at a yearly simple interest rate. He takes 3 years to pay off the loan and interest. He

V125BC [204]

He pays $135 for 3 years. So that’s $45/year. Considering 900 is your 100%, how many percents are represented by $45 in 900?

1)
You can see that 900 = 9x100.
So you can divide 900 by 9 to get 100.
That means you can also divide 45 by 9 (it’s proportional)
You have 45 for 900, you divide by 9 so you get 5 for 100 -> 5%

Or 2)
(Photo)
It’s a cross-multiplication :
(45 x 100)/900 = 5%
So the interest rate is 5%.

(Sorry if it’s confusing, English isn’t my first language..)
