Given data:

The probability of A is P(A)=0.45.

The probability of B is P(B)=0.30.

The expression for the mutually exclusive events is,

The expression for the probability of A union B is,

Thus, the probability of (AUB) is 0.75.

We are told that a 7% tax is applied to the original sales price, in order to determine the tax amount we just have to multiply the original price ($46.85) by the tax percentage (0.07 as 7% in decimal form), then we get:

Tax amount = 0.07×46.85 ≈ 3.28

By adding the tax amount to the original price we should get the final price, like this:

Total purchase price = 46.85 + 3.28 = 50.13

Then, the total purchase price after tax is $50.13

-1 3/4, 14/8, 1.125 and -0.875 correspond to points 1, 8, 6 and 4 respectively on the number line.

Looking at the number line, there are 8 divisions between two points e.g 0 to 1.  

To know the value of  1 division, we divide the value of the distance between two points by the number of divisions:

= 1/8 = 0.125

To find the locations, we just divide the value of the locations with the value of 1 division:

-1 3/4 / 0.125 = -14  (Count 14 divisions to the left of 0) = point 1

14/8  / 0.125 = 14  (Count 14 divisions to the right of 0) = point 8

1.125/ 0.125 = 9 (Count 9 divisions to the right of 0) = point 6

-0.875 / 0.125 = -7  (Count 7 divisions to the left of 0) = point 4

Therefore, the positions of -1 3/4, 14/8, 1.125 and -0.875 on the number line are points 1, 8, 6 and 4 respectively.

The result of the function f(p) = [tex]p^2[/tex] + 3p + 1  for p = -2 is -1

The function is

f(p) = [tex]p^2[/tex] + 3p + 1  

The function is the expression that represents the relationship between the one variable and another variable. If one variable is dependent variable then the another variable will be independent variable.

The values of p = -2

Substitute the value of p in the function and find the solution

f(p) = [tex]p^2[/tex] + 3p + 1  

f(-2) = [tex](-2)^2[/tex] + 3×-2 + 1

f(-2) = 4 - 6 + 1

f(-2) = -1

Hence, the result of the function f(p) = [tex]p^2[/tex] + 3p + 1  for p = -2 is -1

From the image, we are asked the number of sides a polygon can have to form a regular tesselation.

The first step is to understand what a regular tessellation is;

A regular tessellation is a highly symmetric, edge-to-edge tiling made up of regular polygons, all of the same shape. There are only three regular tessellations: those made up of equilateral triangles, squares, or regular hexagons.

This implies that it could either have 3 sides(triangle), four sides(square), six sides(hexagon).

From the given options we can clearly see that 3 sides is the only available option.

Answer:

400 miles each day

Step-by-step explanation:

You have 1600 miles divided into four days.

1600 / 4

We can use the basic fact that multiplying a number by ten simply means shifting everything to the left, for example 2 x 10 = 20, we just shifted 2 to the left and inserted a 0.

So for this problem, we can do the same. Divide 1600 by 100, or 10 x 10, then divide by 4.

1600/16 = 100

16/4 = 4.

Now, since we divided by ten twice before, we can get the right answer by multiplying by ten twice.

4 x 10 = 40

40 x 10 = 400

Two plants

Spider plant 4 days

Cactus plant 6 days

Then find when

4X = 6Y

find m.c.m (minimum common multiple) of 4 and 6

m.c.m (4,6) = 12

SO therefore, if both plants were watered November 30, then

add 12 days to Nov 30

12 days after Nov 30 = December 12

• Chord: ,a line segment connecting ,any two points, in a curve (circle).

• Diameter: ,a chord passing ,through the center ,of the figure.

• Radius: ,a line segment going ,from the center, to any point in the circumference.

The difference between them is that the chord is any two points touching the circumference, the diameter has to go through the center to any two points, and the radius goes from the center to just one point in the circumference.

Then, the line segment that meets the requirements of being the diameter in circle F is segment CD as it passes through the center.

The radius could be CF, DF, and EF. While a chord could be AB.

Answer: CD

Step-by-step explanation:

Hello!

Area is measured in units². Here, the units are feet, so the area would be written as feet² (ft²).

Simplifying the expression:

You can't simplify this because the units are not the same, and this can't measure area because all units of the area have to be squared. The term 6ft has non-squared units.

Observe that the triangles have one pair of congruent angles, and two pair of congruent sides. This means we can demonstrate the congruence using SAS postulate, that is, Side-Angle-Side.

Therefore, the answer is the first option.

Now the last digit is 6 which is greater than 5. So and is even so change we will simply remove this

The rigid transformations of the vertex of the curve are listed below:

(i) (2, 2).

(ii) (2, 3).

In this problem we find the value of a point of a curve f(x), this point (the vertex) must be transformed by using rigid transformations. There are two cases: (i) Vertical translation, (ii) Reflection about the x-axis. The formulas for each case are described below:

Vertical translation

P'(x, y) = P(x, y) + (0, k)

Reflection about the x-axis

P'(x, y) = P(x, y) + (0, - 2 · p)

Where p is the y-coordinate of point P.

If we know that P(x, y) = (2, - 3), then the coordinates for each case are, respectively:

Vertical translation

P'(x, y) = (2, - 3) + (0, 5)

P'(x, y) = (2, 2)

Reflection about the x-axis

P'(x, y) = (2, - 3) + (0, 6)

P'(x, y) = (2, 3)

The transformations of the vertex of the curve are (i) (2, 2) and (ii) (2, 3).
