Answer:

$905.06 dollars

Step-by-step explanation:

Given the following question:

7.25% of 843.88

In order to find the answer, we use the formula to calculate percentages, then we add that answer to the initial cost of the laptop.

[tex]\frac{p\times c}{100}[/tex]
[tex]\frac{7.25\times843.88}{100}=7.25\times843.88=6118.13\div100=61.1813[/tex]
[tex]61.1813[/tex]
[tex]1 < 5[/tex]
[tex]61.18[/tex]

Now add:
[tex]843.88+61.18=905.06[/tex]
[tex]=905.06[/tex]

Which means the laptop after a 7.25% sales tax costs "$905.06 dollars."

Hope this helps.

The gradient of each of the sides of the triangle​ are:

mAB = -2/5

mBC =-14/9

mCA = -3

The gradient of a line passing through two points (x1, y1) and (x2, y2) is given by:

m = (y2 - y1) / (x2 - x1)

Using this formula, we can find the gradients of each side of triangle ABC:

Gradient of side AB:

mAB = (yB - yA) / (xB - xA)

       = (-5 - (-3)) / (7 - 2)

        = -2 / 5

Gradient of side BC:

mBC = (yC - yB) / (xC - xB)

       = (9 - (-5)) / (-2 - 7)

       = 14 / (-9)

       = -14 / 9

Gradient of side CA:

mCA = (yA - yC) / (xA - xC)

       = (-3 - 9) / (2 - (-2))

       = -12 / 4

       = -3

Therefore, the gradients of the sides AB, BC, and CA are -2/5, -14/9, and -3 respectively.

Additional comment

cL is the SI unit "centiliters." The prefix "centi-" mean 1/100 or 0.01 units. Then 18 cL = 18 × 0.01 L = 0.18 L.

mL is the SI unit "milliliters." The prefix "milli-" means 1/1000 or 0.001 units. Then 9 mL = 9 × 0.001 L = 0.009 L.

Answer:

B is answer

Step-by-step explanation:

Answer:

D

Step-by-step explanation:

A and B are linear because both the x-and-y variables are to the power of one

C is linear because, for each increase in 'x' the 'y' value increases by a constant 2

D is not linear because the y-values increase by 4 then 3; not constant

Statistical significance is also known as the risk of  Type I error

Probability is the likelihood or chance that an event will occur. Statistical significance can be used to measure the level of confidence of measured data.

The probability of the type I error is commonly called the significance level of the hypothesis test and is denoted by the symbol α.

Hence we can conclude that statistical significance is also known as the risk of  Type I error

Answer:

geometric sequence

Step-by-step explanation:

In an arithmetic sequence the terms increase or decrease by the same amount each time. In a geometric sequence the terms are multiplied by a common ration.

The given sequence, 2,4,8,16,32 the terms do not increase by a constant number each time and they are instead multiplied by a common ratio.

Eg. to get to 4 from 2 you multiply by 2, to get to 8 from 4 you multiply by 2. this same process happens throughout the sequence therefore this is a geometric sequence

Answer:

The sequence is geometric

Step-by-step explanation:

The sequence is geometric.

Definition of geometric sequence: A sequence where the next number is made by multiplying the common ratio with the previous number.

In this sequence, there is 2, 4, 8, 16, and 32

4 is made by multiplying 2 with the common ratio, which is true

8, is made by multiplying 4 with the common ratio, 2

As you can see, the numbers have a common ratio of 2, which means this sequence is geometric

Answer:160 tiles

Step-by-step explanation:

The room measures 5 m by 8 m, so we need to multiply them to find the total area of the floor to be covered

5 x 8 = 40 m squared

Now the square tile has a side of 0.5 m. All sides on a square are equal. We need to find the area of the square so:

0.5 x 0.5 = 0.25 m squared

Now to find the no. of tiles requires we just divide the floor's area by the tile's area

40 divided by 0.25 = 160

Therefore we need 160 tiles to cover the floor.
