According to Nielsen, adult Americans spend 2.35 hours per day watching television on a weekday, with a standard deviation of 1.93 hours. If a random sample of 40 adult Americans is obtained, determine the probability that a random sample of 40 adult Americans results in a mean time watching television on a weekday of between 2 and 3 hours.

Answer:

74 reais

Step-by-step explanation:

Em uma determinada loja, o lucro obtido com a venda de fones de ouvido x, em reais, pode ser representado pela expressão algébrica 7x-17. Quanto lucro esta loja terá se vender 13 fones de ouvido?

O lucro é representado como 7x - 17

onde x = número de fones de ouvido vendidos

Se 13 fones de ouvido foram vendidos, o lucro será:

(7 * 13) - 17

= 91 - 17

= 74 reais

Answer:

Store T sells apples at the lowest rate

$1.16

Step-by-step explanation:

which of these is a true statemnt

Store R sells apples at the lowest rate

Store T sells apples at the lowest rate

Store s charges a lower rate than Store T

Store t charges the same rate as Store R

Given:

Store R= $1.20 per pound

Store S =$5.00 for 4 pounds

Store T=$3.48 for 3 pounds

Find the price of apple per pound

Store R=1.20 per pound of Apple

Store S=$5.00/4

=$1.25 per pound of Apple

Store T=$3.48/3 pounds

=$1.16 per pound of Apple

From the statements above,

Store T sells apples at the lowest rate

Answer:

Step-by-step explanation:

-5 - 2(3x - 4) = 3(x - 4) + 6

-5 - 6x + 8 = 3x - 12 + 6

-6x + 3 = 3x - 6

3 = 9x - 6

9 = 9x

1 = x

Answer: x =1

Step-by-step explanation:

-5-2(3x-4) = 3(x-4) +6   Apply the distributive property to break it down.

-5-6x+8 = 3x -12 +6   Combine like terms

-6x + 3 = 3x - 6        Add 6x to both sides

+6x         +6x

3 = 9x  -6       Add 6 to both sides

+6        +6

9=9x             Divide both sides by 9

x= 1

Answer:

40 degrees

Step-by-step explanation:

Complementary angles have a sum of 90.

y = 90 - x

The angle is 260 degrees less than six times its complement.

y = 6x - 260

90 - x = 6x - 260

350 - x = 6x

350 = 7x

50 = x

This is the measure of the complement.

y = 90 - x

y = 90 - 50

y = 40

This is the measure of the first angle.

Answer:

Step-by-step explanation:

Given the upper-left coordinates on a rectangle as (-5, 6), and the upper-right coordinates as (-2, 6), the distance between the two coordinates will be equal to the length of one side of the rectangle. Using the formula for calculating the distance between two points as shown;

D = √(x2-x1)²+(y2-y1)²

The the upper left coordinates be A (-5, 6) and  the upper right coordinates be B(-2, 6).

AB = √(-2-(-5))²+(6-6)²

AB = √(-2+5)²

AB = √3²

AB = 3 units = Breadth of the rectangle

Give the perimeter of the rectangle to be 16 units, we can get the length of the rectangle using the formula;

Perimeter of a rectangle = 2(L+B)

16 = 2(3+L)

16 = 6+2L

10 = 2L

L = 5units

The length of the triangle is 5units

Answer:

A. g(x) = -2^x.

Step-by-step explanation:

If g(x) = -2, it would be a straight line running horizontally.

If g(x) = -x, it would be a linear equation.

If g(x) = -|x|, it would be an absolute value function, which is a graph in a v-shape.

So, the remaining answer is that A. g(x) = -2^x.

Answer:

  16 cm

Step-by-step explanation:

A "right" prism is one that has the planes of the lateral faces perpendicular to the plane of the base. Here, we assume your "right triangular prism" is one that has a right triangle as a base, because you mention the "hypotenuse."

The area of the base is ...

  A = (1/2)bh = (1/2)(12 cm)(12 cm) = 72 cm²

The volume of the prism is ...

  V = Bh . . . . where B represents the area of the base

Filling in the numbers, we have ...

  1152 cm³ = 72 cm²×h

  h = (1152/72) cm = 16 cm

The height of the prism is 16 cm.

Answer:

16 cm

Answer: $70.65

Step-by-step explanation:

From the question, we are informed that Mica has $22.50 in her bank account and then she goes to the market to get groceries for the week and ends up spending more than planned. She later checks her account and found out that she now has a balance of $-48.15.

To get the amount of money that Mica spent at the market, we subtract her balance from the opening balance she had in her bank account. This will be:

= $22.50 - (-$48.15)

= $22.50 + $48.15

= $70.65

Mics spent $70.65 at the market.

Answer:

7.5

Step-by-step explanation:

The area of a triangle is found by the formula A=1/2bh, where b is the base length, and h is the height. If we count the squares, we can find that the base length of the triangle is 3 units, and the height is 5 units. If we plug those numbers into the equation to get A=1/2*3*5, we can solve to get A=7.5

Answer:

The number of copies can be any number greater than or equal to 1.

Explanation:

Remove the descriptions involving costs because that explains the range of the graph and not the domain.

The number of copies can be either 1, 2, 3, 4, 5, 6, or 7.

This description is false. There are an unlimited amount of copies you can make and not only up to 7 copies. Other wise the graph would end at x = 7.

Speaking of unlimited, the last choice is correct because you can get 1 copy or more than 1.

Answer:

equation: x^2+12x-220 = 0

factored form: (x-10)(x+22) = 0

solution: x=10 or x=-22

dimensions: 4 cm, 11 cm, and 21 cm.

Step-by-step explanation:

Given:

Volume = 924

dimensions of cuboid = 4, (x+1), (x+11)

Solution

Calculate volume

4(x+1)(x+11) = 924

simplify

(x+1)(x+11) = 231

Expand

x^2+12x+11 = 231

Simplify

x^2+12x-220 = 0

Factor  

x^2-10x + 22x -220 = 0

x(x-10) + 22(x-10) = 0

(x-10)(x+22) = 0

x=10 or x=-22

Since x=-22 will give rise to negative dimensions, root will be rejected.

For x=10, the dimensions can be obtained by substituting x=10

x+1 = 11

x+11 = 21

So dimensions are

4 cm, 11 cm, and 21 cm.

Check: 4*11*21 = 924 checks.

Answer:

1 hour   : 15 dollars

2 hours: 20 dollars

3 hours: 25 dollars

4 hours: 30 dollars

5 hours: 35 dollars

Step-by-step explanation:

Substitute the hour number in for h and solve. for example, if you were trying to find 5 hours, you would produce the equation c = 5(5) + 10. once you solve that you get c = 25 + 10 which is also c = 35.

The quotient of the equation 4x³ + 2x² + 50 ÷ 2x + 5 using long division method is 2x² - 4x

4x³ + 2x² + 50 ÷ 2x + 5

Answer: 90 degrees

Step-by-step explanation: Each of these angles are at 90 degrees since there is a square box at each of their second points.

Answer:

First by 3, second by -2.

Step-by-step explanation:

You need to get the x-factor to the smallest common multiple of 4 and 6, which is 12.

But also, if you add both, they should cancel out the x term, i.e.,:

-12x + 12x = 0

You get that by multiplying by 3 and -2, respectively.

Answer:

35 (the sequence is 1,2,18,19,35)

Step-by-step explanation:

So you have 5 numbers a, b, 18, c, d ordered from low to high.

18 is given because it is the median.

If the mean is 15, the sum must be 75 (because 75/5=15).

d must be as high as possible, so the others must be as low as possible, but positive and different.

So let's say a=1 and b=2, we can't get any lower than that.

c can be no lower than 19, otherwise we'd lose the median.

That leaves for d = 75 - 19-18-2-1 = 35.

nice one

The largest possible integer for the given case is 51.

In order to find the mean, first sum all the values of the data and count the number of data then divide them.

In order to find the median, first check whether the number of data is even or odd. For even number, the median is n/2 th element of the sample and for odd number the median is (n + 1)/2 th element.

Given that,

The mean of five integers is 15.

And, the median is 18.

Since the median of n number of data in a sample when n is odd is given as,

Median = ((n+1)/2) th element.

For n = 5, the median is 3rd element.

Which implies the 3rd element is 18.

Now, sum of the five integers is given by 5 × Mean which is,

5 × 15

= 75.

Suppose the five integers are x₁, x₂, x₃, x₄ and x₅ respectively.

Then as per the question,

x ₁+ x₂ + x₃+ x₄+ x₅ = 75

And, x₃ = 18

Then,  x ₁+ x₂ + 18 + x₄+ x₅ = 75

=>  x ₁+ x₂ + x₄+ x₅ = 75 - 18

=>   x ₁+ x₂ + x₄+ x₅ = 57    

In order two find the largest possible integer, suppose the remaining three of them are 1, 2 and 3.

The equation can now be written as,

1 + 2 + 3 + x₄ = 57

=> x₄ = 51

Hence, the maximum possible value of the largest integer is 51.
