When you get home to plant the flowers, you have 3 different flowerbeds in which you plan on planting flowers. You have two flowerbeds where you want the same ratio for tulips to daffodils. In one of these flowerbeds you have 6 tulips and 8 daffodils. The other flowerbed you have 4 daffodils.

How many tulips should there be in the second flowerbed to have the same ratio of tulips and daffodils as the first flower bed?


How many total daffodils are used in these two flowerbeds?

Answer:

w<50

c≤30

6w+2c≥320

Step-by-step explanation:

W stands for the car wash, and C stands for the cakes. Naturally, it would be 7w+4c≥320 but each cake costs $2 to make and each car wash costs $1 per car. This makes the system 6w+2c≥320. They will wash less than(<) 50 cars and bake no more than(≤) 30 cakes. I hope this helped :).

To solve the problem we must know about Expressions.

In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.

Given to us

Earning per car wash = $7

Earning per cake  = $4

Cost of supplies per car wash = $1

Cost of cake = $2

They will wash less than 50 cars and

Bake no more than 30 cakes

They want to raise at least $320

Assumption

Let the number of cakes they sold be represented by x, and the number of car washes they did be represented by y.

Profit from Car wash

= Earning per car wash - Cost of supplies per car wash

= $7 - $1

= $6

Profit from Cake

= Earning per Cake - Cost of a cake

= $4 - $2

= $2

The system that represents profit

$320 = ($6)y + ($2)x

320 = 6y + 2x

As it is given that they will not make more than 30 cakes, therefore,

x ≤ 30

As it is given that they will wash less than 50 cars.

y < 50

Hence, the following equations can represent the system,

Answer:

2, (x+13)/6, -7

Step-by-step explanation:

The -1 bit means do it backwards, so look the for the output of the function with the value given.

In g, when we put in 2 we get 9 out, so g^-1(9) is 2.

For the second one we need to rearrange it to get x = something.

h(x) + 13 = 6x

x = (h(x) + 13)/6

Then replace the h(x) with x and the x with h^-1(x) to get

h^-1(x) = (x + 13)/6

The last one is a trick. Note that h and h^-1 are opposites. If we do something then do the opposite of it, we haven't done anything at all! So the number stays the same.

Answer:

The answer is below

Step-by-step explanation:

For a normal distributed population with a mean (μ), and a standard deviation (σ), if a sample size of n is selected from the population, the mean of the sample ([tex]\mu_x[/tex]) =  μ and the standard deviation of the sample ([tex]\sigma_x[/tex]) = [tex]\frac{\sigma }{\sqrt{n} }[/tex]

Let the normal distribution population have a standard deviation of σ. If the standard deviation is to be decreased by half, the sample size (n) needed is:

[tex]Using:\\\\\sigma_x=\frac{\sigma}{\sqrt{n} } \\\\but\ \sigma_x=\frac{\sigma}{2}\\\\Hence:\\\\ \frac{\sigma}{2}=\frac{\sigma}{\sqrt{n} }\\\\Divide\ through\ by \ \sigma\ to\ get:\\\\ \frac{1}{2}=\frac{1}{\sqrt{n} }\\\\\sqrt{n}=2\\\\square\ both\ sides:\\\\(\sqrt{n} )^2=2^2\\\\n=4\\\\[/tex]

To decrease the standard deviation of the sampling distribution by half we need a sample size of 4

Answer:

The angle of elevation from the base to the top of the mountain is 30°.

Step-by-step explanation:

Given: Vertical height of mountain is 650 feet and the distance from the top of the mountain to the base is 1300 feet.

To find: The angle of elevation from the base to the top of the mountain.

Let AB be the height of mountain and BC be the base.

Then, according to question, AB=650 feet and AC=1300 feet.

Let ∠ACB=[tex]\Theta[/tex].

Then, in ΔABC,

[tex]sin\Theta=\frac{AB}{AC}[/tex]

⇒[tex]sin\Theta=\frac{650}{1300}[/tex]

⇒[tex]sin\Theta=\frac{1}{2}[/tex]

⇒[tex]\Theta=30[/tex]°

Hence, the angle of elevation from the base to the top of the mountain is 30°.

Step-by-step explanation:

Given that:

Percentage of those having health insurance = 71%

p = 71 / 100 = 0.71

Number of adults selected at random, n = 4

Probability that 4 selected have health insurance :

p^n = 0.71^4 = 0.25411681

The required estimate of the area in square inches of the stove top that does not include the area of the burners is 415 square inches.

Surface area is defined as the measure of a region or surface is called as surface area.

The best estimate of the area of the stovetop that does not include the area of the burners can be obtained by subtracting the total area of the four burners from the total area of the stovetop.

The total area of the stove top is given by the product of its length and width:

Length = 24 inches

Width = 22 inches

Area = Length × Width = 24 × 22 = 528 square inches

The area of each burner is given by the formula for the area of a circle:

= π × (diameter/2)²,
where π is approximately equal to 3.14

Since the diameter of each burner is 6 inches, the radius of each burner is 6/2 = 3 inches.

Area of one burner = Pi × (3)² = 3.14 × 9 = 28.26 square inches

The total area of the four burners is 4 × 28.26 = 113 square

The area of the stove top = 528 - 113
                                       = 415 square inches.

Thus, the required estimate of the area in square inches of the stove top that does not include the area of the burners is 415 square inches.

Step-by-step explanation:

Answer:

The dimension of box=[tex]2ft\times 2ft\times 1ft[/tex]

Step-by-step explanation:

We are given that

Volume of box=4 cubic feet

Let x be the side of square base and h be the height of box

Volume of box=[tex]lbh=x^2h[/tex]

[tex]4=x^2h[/tex]

[tex]h=\frac{4}{x^2}[/tex]

Now, surface area of box,A=[tex]x^2+4xh[/tex]

[tex]A=x^2+4x(\frac{4}{x^2})=x^2+\frac{16}{x}[/tex]

[tex]\frac{dA}{dx}=2x-\frac{16}{x^2}[/tex]

[tex]\frac{dA}{dx}=0[/tex]

[tex]2x-\frac{16}{x^2}=0[/tex]

[tex]2x=\frac{16}{x^2}[/tex]

[tex]x^3=8[/tex]

[tex]x=2[/tex]

[tex]\frac{d^2A}{dx^2}=2+\frac{32}{x^3}[/tex]

Substitute x=2

[tex]\frac{d^2A}{dx^2}=2+\frac{32}{2^3}=2+4=6>0[/tex]

Hence, the area of box is minimum at x=2

Therefore, side of square base,x=2 ft

Height of box,h=[tex]\frac{4}{2^2}=1 ft[/tex]

Hence, the dimension of box=[tex]2ft\times 2ft\times 1ft[/tex]

Answer:

Step-by-step explanation:

Given the data table :

x : __ $2_ $14_ _$20 __ $100

P(x) : 0.40_ 0.20 _0.20 _0.20

The mean :

E(x) = Σ(x*p(x))

E(x) = (2*0.4) + (14*0.2) + (20*0.2) + (100*0.2)

E(x) = 27.6

The standard deviation :

SD(x) = sqrt(Σ(x² * p(x)) - E(x)²)

Σ(x² * p(x)) - E(x)² :

((2^2*0.4) + (14^2*0.2) + (20^2*0.2) + (100^2*0.2)) - 27.6^2

2120.8 - 761.76

= 1359.04

Sqrt(1359.04)

SD(x) = 36.865159

SD(x) = 36.87

Answer: $65; $35+r•2

Step-by-step explanation:

So if every ride Brayden goes on costs $2 and he rides 15 rides, 2•15= $30 from rides alone. Then you add the $35 from admission to that number to get $65. This works for any amount of rides, just change the number to how many rides he goes on and use the same formula, 35+r•2 where r equals the number of rides ridden.
