Answer:

no correlation

Step-by-step explanation:

The price of the smartphone is fixed beforehand, therefore price does not depend upon the number of units sold.

Hence, there is no correlation between the two given variables.

Hence, no correlation would be the answer.

Answer:

Pi/4

Step-by-step explanation:

first we have to figure out what cos of 7pi/4 is. Using the unit circle, we know that it is equal to root2/2. Cos to the negative 1 is basically just finding the radian value that matches the value in the parenthesis. This means we have to find the corresponding radian to root2/2. Using the unit circle, we find this to be pi/4

1/2(13-5)+(4+8)^2

A. 148

B. 144

C. 20

D. 16

We must follow "PEMDAS" order of operations rules.  Anything inside parentheses must be done first, followed by exponentiation, multiplication and division, and finally additionl and subtraction.

1/2(13-5)+(4+8)^2 has three sets of parentheses enclosing mathematical expressions:  (1/2), (13 - 5) and (4 + 8).  These evaluate to:

                        1/2,       8,               12

and so we now have (1/2)(8) + (12)^2

Exponentiation is next.  We get:  (1/2)(8) + 144

Next is multiplication:                         4      + 144

Last is addition:                                       148

Answer A is correct:  148

8 x 9+4^2-(63/7)

is evaluated in the same way:

8 x 9+4^2-(9), followed by exponentiation:

8*9 + 16 - 9, followed by multiplication:

72 + 16 - 9 = 79 (Answer C)

Volts per bowling alley = 13

The ratio of the number of votes for skating to the number of votes for bowling is:

Total area to paint: (15 + 10) - 1.5 = 23.5 sq ft

Calculate the area of each wall, subtract the door area, and sum the areas.

Front and back walls: (3 * 2.5) * 2 = 15 sq ft

Next, we calculate the area of the side walls:

Side walls: (2 * 2.5) * 2 = 10 sq ft

Door area: 1.5 * 1 = 1.5 sq ft

Total area to paint: (15 + 10) - 1.5 = 23.5 sq ft

Answer:

The tank's capacity is 500 liters

Step-by-step explanation:

Proportions

The tank initially contains 50 liters of water. The tank's capacity is more than that, as we'll show later.

We know after 20 minutes of leaking from the tank, 40 liters still remain. This means 10 liters have leaked in 20 minutes. The loss of water occurs at a constant rate or 10/20=0.5 liters per minute.

After 30 more minutes, the tank has lost 0.5*30 = 15 more liters of water and now has 40 - 15 = 25 liters remaining.

We are told those 25 liters correspond to 5% of the tank's full capacity. Thus, the full capacity of the tank is:

\(\displaystyle \frac{25 }{ (5 / 100)} = 500~liters\)

The tank's capacity is 500 liters

Answer:

$432.9

Step-by-step explanation:

The z score is used to determine by how many standard deviations the raw score is above or below the mean. The z score is given as:

\(z=\frac{x-\mu}{\sigma}\\\\where\ x=raw\ score, \mu=mean,\sigma=standard\ deviation\)

Given that μ = $400, σ = $20

P(z > z*) = 0.05

P(z < z*) = 1 - 0.05 = 0.95

z* = 1.645

\(z=\frac{x-\mu}{\sigma} \\\\1.645=\frac{x-400}{20}\\\\x-400=32.9\\\\x=432.9\)

Therefore $432.9 should be budgeted for weekly repairs and maintenance so that the probability the budgeted amount will be exceeded in a given week is only 0.05.

The total area of the three triangles is square units is 36 and the area of the figure is square units is 60.

The triangle can be defined as a three-sided polygon in geometry, and it consists of three vertices and three edges. The sum of all the angles inside the triangle is 180°.

From the figure, the area of triangles can be calculated using the:

Area = (1/2)height×base length

Area of three triangle = 1/2(4×6) + 1/2(6×4) + 1/2(4×6)

Area of three triangle = 1/2(24×3) = 36 square units

Area of the figure = area of three triangle + area of the rectangle

= 36 + 6×4

= 60 square units

Thus, the total area of the three triangles is square units is 36 and the area of the figure is square units is 60.

The y-intercept of the function is (0, c)

The coefficients b determine the horizontal shift of the parabola compared to the parent function

If a is negative, the parabola opens downward

The y-intercept of the function is (0, c).

This means that when x = 0, the y-value is equal to c.

The constant term c represents the y-coordinate of the point where the parabola intersects the y-axis.

The coefficient b determines the horizontal shift of the parabola compared to the parent function.

The value of b affects the position of the vertex and determines if the parabola is shifted to the left or right.

A positive value of b shifts the parabola to the left, while a negative value of b shifts it to the right.

If a is negative, the parabola opens downward.

The coefficient a determines the shape of the parabola.

If a is positive, the parabola opens upward, and if a is negative, the parabola opens downward. The sign of a determines the direction in which the parabola faces.

Answer:

To find the amount of the sales tax, we need to multiply the bill amount by the tax rate of 3% or 0.03:

Sales tax = 0.03 x $16.05 = $0.48

To find the total amount of the bill after the sales tax was added, we need to add the bill amount to the sales tax:

Total bill = $16.05 + $0.48 = $16.53

To find the amount of the tip, we need to calculate 18% of the total bill after the sales tax was added:

Tip = 0.18 x $16.53 = $2.98

In this case, we are to determine the probability of selecting two even numbers. This can be solved as follows:There are six even numbers: {2, 4, 6, 8, 10, 12}.We can use the concept of conditional probability since the first event affects the probability of the second event. This can be expressed as follows:

In this case, P(A) represents the probability of selecting an even number, and P(B|A) represents the probability of selecting an even number given that the first card selected was even. P(A) = 6/12 = 1/2 (there are six even numbers and twelve cards in total)P(B|A) = 5/11 (there are five even numbers left in the box after the first even number is selected, and eleven cards are left in total).

The probability of selecting two even numbers can be found by multiplying these probabilities: P(A) x P(B|A) = (1/2) x (5/11) = 5/22Therefore, the probability of selecting two even numbers is 5/22.Answer: 5/22

Answer:

The answer is A.

Step-by-step explanation:

a+b=c+d

Given the expression,

11 + 7 = 5 + 13, where a= 11

b= 7

c= 5

d= 13

From the options, taking option A:

(5 + 6) + 7 = 5 + (6 + 7)

5 + 6= 11= a

6 + 7 = 13= d

Therefore from the comparison above, we can see that option A is the best form of expression that correctly interpretes the given expression

To find the average rate of change of the function f(x) = x² - 4x + 1 from x=3 to x = 5, we need to find the difference in f(x) between these two values and divide by the difference in x:

f(5) - f(3) / (5 - 3)

= (5² - 4(5) + 1) - (3² - 4(3) + 1) / 2

= (25 - 20 + 1) - (9 - 12 + 1) / 2

= (6) / 2

= 3

Therefore, the average rate of change of f(x) from x=3 to x=5 is 3.

Step-by-step explanation:

Given a interval x=a to x=b, the average rate of change is equal to

\( \frac{f(b) - f(a)}{b - a} \)

where [a,b] is the interval.

Here

a is 3

b is 5 so

\( \frac{f(5) - f(3)}{5 - 3} \)

Using the function

\(f(5) = 25 - 20 + 1 = 6\)

\(f(3) = 9 - 12 + 1 = - 2\)

So

\( \frac{6 - ( - 2)}{5 - 3} = 4\)

The average rate of change of f from x=3 to x=5 is 4
