Answer:

286

Step-by-step explanation:

Given :

Mean (m) = 284

Standard deviation (s) = 5.5

P(Z > x) = 0.34

According to the standardized formula :

Zscore = (x - m) / s

Uaing the Z probability calculator ; The Z value at P(Z > x) = 0.34 is 0.412

Hence, Zscore = 0.412

Zscore = (x - m) / s

0.412 = (x - 284) / 5.5

5.5 * 0.412 = x - 284

2.266 = x - 284

x = 2.266 + 284

x = 286.266

x = 286 (nearest whole number)

Answer:

The answer would be 30

Step-by-step explanation

For positive integers: 2 ⋅ 3 ⋅ 5 ⋅ 7 ⋅ 11 = 2310 For all integers: ± ( 2 ⋅ 3 ⋅ 5 ) = ± 30 For Gaussian integers: ± 1 ± 3 i and ± 3 ± i (all combinations of signs) Explanation: A prime number is a number whose only factors are itself, units and unit multiples of itself. So in the positive integers, the first few primes are: 2 , 3 , 5 , 7 , 11 , ... So the smallest composite positive integer with the five smallest prime positive integers as factors is: 2 ⋅ 3 ⋅ 5 ⋅ 7 ⋅ 11 = 2310 If we extend our interest to include negative integers, then the smallest primes are: 2 , − 2 , 3 , − 3 , 5 , − 5 , ... So the smallest composite integers with the five smallest prime integers as factors are: ± ( 2 ⋅ 3 ⋅ 5 ) = ± 30 If we consider Gaussian integers, then the smallest primes are: 1 + i , 1 − i , − 1 + i , − 1 − i , 1 + 2 i , 1 − 2 i , − 1 + 2 i , − 1 − 2 i , 2 + i , 2 − i , − 2 + i , − 2 − i , 3 , − 3 ,... So the smallest composite Gaussian integers with the five smallest prime Gaussian integers as factor are: ( 1 + i ) ( 1 + 2 i ) = − 1 + 3 i , 1 + 3 i , − 1 − 3 i , − 1 + 3 i , 3 + i , 3 − i , − 3 + i , − 3 − i

Answer:

6.3 sq ft

Step-by-step explanation:

Area of entire Δ = 1/2·(4)(1.9+3.1)

                           = 2(5)

                           = 10 sq ft

Area of unshaded Δ = 1/2 ·(4)·(1.9)

                                  = 2(1.9) =3.8 sq ft

Area of shaded Δ = 10.0 - 3.8 = 6.2 sq ft

Answer:

Pagarás 30.25 euros por la falda

Step-by-step explanation:

Porcentajes

Si necesitamos agregar un porcentaje a una cantidad conocida podemos hacerlos de dos formas: Calculamos el monto del aumento y se lo sumamos a la cantidad original, o también calculamos el porcentaje aumentado y lo aplicamos a la cantidad original. Lo haremos de las dos formas:

La falda costaba 25 euros y se le cargará un 21% de IVA.

El aumento sería:

25*21/100=5.25 euros

El precio final es

25+5.25=30.25 euros

De la segunda forma. El costo original era el 100%, con el 21% de aumento sería 121%. Aplicamos el 121% al precio original para obtener:

25*121/100=30.25 euros

Se obtiene el mismo resultado: Pagarás 30.25 euros por la falda

Answer:

1. AT&T would be best for 2 year plan

2. Verizon would be best for 7 year plan

3. Point A is where both intersects showing the the time where both are at the same price. It also shows that after that point, is where verizon would be a better pick

Step-by-step explanation:

At&T is best for 2 year plan because for 2 years, it is less then $160 which is how much the Verizon plan costs for 2 year looking at the graph.

Verizon is best for 7 year as at the 6th year, AT&T is much more higher than Verizon meaning that if both lines keeps going on, Verizon will be cheaper for the long term

Even though Verizon may be expensive at first, after the point A, it shows that Verizon would be a better choice if you are going to use it for 3+ years.

[tex]x \geqslant - 4[/tex]

Step-by-step explanation:

Domain is the set of x-values. We look at the graph and look for the start of x-value.

The start of domain begins at x = -4 and has no ending (positive infinity.)

Thus, our answer is x >= -4

Answer:

See attached image for the requested graph

Step-by-step explanation:

The values completed in the table and text boxes as shown, are all correct.

For the plotting of the points and drawing of the line, please see the attached image.

a. By putting the value of x one by one table can be completed

The complete table is attached below.

b. The graph is attached below.

c. solution of the given equation is x = 1.5.

Use the concept of fucntion which is defined as:

A relation between a collection of inputs and outputs is known as a function.

A function is, to put it simply, a relationship between inputs in which each input is connected to precisely one output.

The given fucntion is:

y = 6 - 2x

Since we know that this equation has degree one,

Therefore, it represents the equation of a line

Now to complete the table put the value of x in the fucntion one by one:

Put x = 0:

y = 6 - 2(0)

y = 6

Put x = 1:

y = 6 - 2(1)

y = 4

Put x = 2:

y = 6 - 2(2)

y = 2

Put x = 3:

y = 6 - 2(3)

y = 0

Put x = 4:

y = 6 - 2(4)

y = -2

Put x = 5:

y = 6 - 2(5)

y = -4

b. Now with the help of this table draw the graph of this fucntion.

The graph of it is attached below.

c. To solve the equation:

6-2x  = 3

Subtract 6 on both sides,

-2x = -3

Divide both sides by -2 we get.

x = 1.5

Hence,

The solution of the given equation is 1.5.

Step-by-step explanation:

are you asking a question or not?

Answer:

r = 4 units

Step-by-step explanation:

From the question it is not clear that what you want to ask. But as per me you are interested in finding the radius of the circle.

Since, circle is touching y-axis at has a center (-4, 8) so it's radius will be equal to the x-coordinate.

Here, x - coordinate is - 4

Since radius is a non negative number.

So, r = 4 units

Answer:

The expected net gain to the player for one play is -$0.0526.

Step-by-step explanation:

To find the expected net gain, we multiply each outcome by its probability:

Player wins:

Earns $35.

1 out of 38 numbers, so probability 1/38.

Player loses:

Loses $1.

37 out of 38 numbers, so probability 37/38.

Expected value:

[tex]\frac{1}{38} \times 35 - \frac{37}{38} \times 1 = -\frac{2}{38} = -0.0526[/tex]

The expected net gain to the player for one play is -$0.0526.

Answer:

y = ½x

_____

k = ½

Step-by-step explanation:

[# of donuts] 2 → [total price] $1

[# of donuts] 12 → [total price] $6

[# of donuts] 3 → [total price] $1.50

[# of donuts] 7 → [total price] $3.50

Because price is the dependent variable, it is the y value. And since the price is the y variable, the donuts must be the x value.

Because the price is ½ the # of donuts, y is ½ x which means y = ½x and k = ½.

Answer:

Step-by-step explanation:

x = 1

Step 1: Simplify both sides of the equation.

20x−−2x−16=6

20x+2x+−16=6

(20x+2x)+(−16)=6(Combine Like Terms)

22x+−16=6

22x−16=6

22x−16+16=6+16

22x=22

Step 3: Divide both sides by 22.

Step-by-step explanation:

We are given that an expression

[tex]3\frac{2}{5}+(-7\frac{1}{5})[/tex]

We have to find the expression which shows the sum of integer and fractional parts.

The given expression can be written as

[tex]3+\frac{2}{5}+(-7-\frac{1}{5})[/tex]

Now, adding integers

[tex](3+(-7)+\frac{2}{5}+(-\frac{1}{5})[/tex]

Now, adding fraction parts we get

[tex]3+(-7)+(\frac{2}{5}+(-\frac{1}{5}))[/tex]

Hence, the expression which shows the given expression as a sum of integers and fractional parts is given by
