Based on the given equation y = 195(1.10)^x, where x represents the number of years since 2005 and y represents the number of Salad Supreme restaurants, we can draw the following conclusions:

A. Salad Supreme had 110 restaurants in 2005: This conclusion is not supported by the given equation.

B. Salad Supreme is increasing the number of restaurants by 10% each year: This conclusion is supported by the equation.

C. Salad Supreme is increasing the number of restaurants by 195 each year: This conclusion is not supported by the equation.

D. Salad Supreme is increasing the number of restaurants by 110% each year: This conclusion is not supported by the equation. The growth factor of 1.10 (or 10%) indicates a 10% increase each year, not 110%.

Therefore, the most reasonable conclusion based on the given information is: Salad Supreme is increasing the number of restaurants by 10% each year.

Answer:

Number of 2 digit number: 10 to 99, 90 numbers. Hence,P(selecting a 2 digit number) = 1/90 = .

Step-by-step explanation:

The minimum cost is $1500.

The vertex form of a quadratic function is f(x) = a(x – h)² + k, where a, h, and k are constants of the parabola is at (h, k).

Given:

y =1/30 x²-2x+1530

y= 1/30 x² - 2x + 1530

comparing the above equation with y ax²+ bx +c we get

a = 1/30

b = -2

c = 1530

Now, the the x coordinate of the vertex

h = -b/(2a)

h = -(-2)/(2x(1/30))

h = 2/(2/30)

h = (2/1) x (30/2)

h = (2 x 30)/(1 x 2)

h = 60/2

h = 30

So, The x coordinate of the vertex is 30.

Now, we plug in x = 30 to find the y coordinate of the vertex.

y =1/30 x²-2x+1530

y =1/30 (30)²-2(30)+1530

y =1/30 (900)-60+1530

y= 1500

Thus, the minimum cost is $1500

Answer:

it is 12 cm squared

Step-by-step explanation:

you do 4 times 3 to get the area

answer: the range is 41.

to find the range of this data set, we first need to find the minimum and maximum values - which are 59 and 100.

then we subtract the minimum from the maximum.

59 - 100 = 41.

The value of the two numbers in b is 15 and 18

To get the values we would have to set up an equation system

Such that we would have:

the smaller number is given as c

Then the bigger number is given as c + 3

The equation would be

c + c + 3 = 33

then

2c = 33 - 3

2c = 30

From here we would have to divide both sides of the equation by 2

2c / 2 = 30 / 2

c = 15

33 - 15 = 18

Hence the numbers are given as 15 and 18

Step-by-step explanation:

The weight of the granite pyramid in tons is 1350 tons.

A pyramid is a three-dimensional shape.

The granite pyramid is 50 feet high and has a square base of 30 feet on a side.

Granit weighs 180 pounds per cubic foot.

Therefore, the weight in tons of the pyramid can be calculated as follows;

Hence,

volume of the granite pyramid = 1 / 3 b² h

Therefore,

volume of the granite pyramid = 1 / 3 × 30² × 50

volume of the granite pyramid = 45000 / 3

volume of the granite pyramid = 15000 ft³

Hence,

1 ft³ = 180 pounds

15000 ft³ = ?

weight = 2700000 pounds

1 pounds = 0.0005 tons

2700000 pounds = ?

Therefore,

weight of the pyramid granite in tons = 1350 tons

To find the area, split the floor shape into two shape.  

One is trapezoid and the other is parallelogram.  

Let's count the grid given.  

The parallels sides of trapezoid are 7 ft and 4 ft, height is 7 ft.  

The base and height of the parallelogram are 4 ft and 4 ft respectively.  

Area of the trapezoid \(=\frac{1}{2}*(\)\(sum\) \(of\) \(parallel\) \(sides)*height\)

                                \(=\frac{1}{2}*(7+4)*5\)

                                \(=\frac{1}{2} *11*5\)                              

Area of the trapezoid = 27.5 sq.ft  

Area of the parallelogram = base × height  

                                       = 4 ft × 4 ft  

Area of the parallelogram = 16 sq. ft  

Total area = 27.5 sq. ft + 16 sq. ft  

              = 43.5 sq. ft  

Cost of area per sq. ft = $1.95  

Cost of area 43.5 sq. ft = 43.5 × 1.95

                                   = $84.825

                                   = $84.83  

Hence Sal will pay $84.83 to tile his entryway.

Initially, 1/4 of the tank was filled.

After adding 12 gallons, it was 3/4 full.

Increase in fuel filled portion =

\(\dfrac{3}{4} -\dfrac{1}{4} =\dfrac{3-1}{4} =\dfrac{2}{4}\)

So 2/4 of the tank = 12 gallons

1/4 of tank \(= 12 \div 2 = 6\) gallons

4/4 of tank \(= 6\times4 = 24\) gallons

____________________

Portion remaining to be filled =

\(1-\dfrac{3}{4} =\dfrac{4-3}{4} =\dfrac{1}{4}\)

Fuel needed \(= \dfrac{1}{4} \times 24 = 6\) gallons

So you need 6 more gallons to fill the tank

We know that there are 16 girls. That is the first part of the ratio. Now, it says girls to students, which mean you have to add up the total of girls and boys together. 12+16=28. There are 28 students in total. Now, you have the ratio of 16:28. But, it says simplified...so we need to divide both sides of the ratio by a number. Let's choose 4 because 4 can go both into 16 and 28. 16/4=4. 28/4=7. So, the simplified ratio of girls to students in the classroom is 4:7.

The line of best fit is simply the trending line of a graph

Student A creates a better line of best fit

The linear equations are given as:

\(\mathbf{y = -2x + 24}\)

\(\mathbf{y =1.5x + 23}\)

The given graph shows a negative linear association.

This is so because, as the x-values increases, the y-values decreases.

This in other words means that:

The slope of the graph is negative

A linear graph is represented as:

\(\mathbf{y = mx + c}\)

Where: m represents slope

By comparison

m = -2 and m = 1.5 for the equations of the two students.

Because the slope of the graph is negative, then

m =-2 is correct

Hence, student A creates a better line of best fit

Answer:

SU=6

TU=6

ST=12

Step-by-step explanation:

SU and TU are equal because their hypotenuses are equal (10).

With this knowledge, you know that 2x+2=3x.

Subtracting 2x from both sides shows that x=2, so you can substitute that into the original line segment values in order to get 6 for both SU and TU. Double this to find the value of ST (12).

(a) To compute the experimental probability of rolling a 1 or 6 from Latoya's results, we need to determine the number of times a 1 or 6 was rolled and divide it by the total number of rolls Latoya made.

Let's assume that Latoya rolled the dice 100 times and obtained 20 1's and 10 6's. The total number of successful outcomes (rolling a 1 or 6) is 20 + 10 = 30.

Therefore, the experimental probability of rolling a 1 or 6 is 30/100 = 0.3 or 30%.

(b) Assuming the cube is fair, the theoretical probability of rolling a 1 or 6 can be determined by considering the favorable outcomes (rolling a 1 or 6) divided by the total possible outcomes (rolling any number from 1 to 6).

Since there are two favorable outcomes (1 and 6) out of six possible outcomes (1, 2, 3, 4, 5, 6), the theoretical probability is 2/6 = 1/3 or approximately 0.3333.

(c) The correct statement is B. As the number of rolls increases, we expect the experimental and theoretical probabilities to become closer, though they might not be equal. This is due to the law of large numbers, which states that as more trials are conducted, the experimental probability tends to converge towards the theoretical probability. However, it is not necessary for them to be exactly equal. Random variations can cause some discrepancy, but with a larger number of rolls, the experimental probability should approach the theoretical probability more closely.
