Venn diagrams are pictorial representations of set notations

Represent the event that a student plays tennis with A, and the event that a student is right-handed with B

So, we have the following notations

n(A) = 40%

n(B) = 85%

n(A n B) = 30%

Next, we draw the Venn diagram where the intersection of A and B is represented with 30%

See attachment for the Venn diagram

Answer:

The slim-off diet claims the largest loss.

Step-by-step explanation:

The slim off claims to lose 3.5kg(7.7 pounds) in a week,

whereas super slim claims to lose 6 pounds in 2 weeks.

Answer:

3.5 kg

Step-by-step explanation:

if you convert 6 Ib and 3.5 kg to grams you get

6 Ib = 2721.6 grams

3.5 kg = 3500 grams

Since 3.5 kg has more grams lost from the diet.

The horizontal distance between the base of the skyscraper to the ship is 1145 feet.

Data;

Using trigonometric ratios, we have the value of adjacent and angle, we can easily use tangent of the angle to find the horizontal distance

[tex]tan\theta = \frac{opposite}{adjacent}[/tex]

Substitute the values into the equation and solve

[tex]tan45 = \frac{x}{1145}\\ x = 1145tan45\\x = 1145ft[/tex]

x < 1

Step-by-step explanation:

x - 4 < - 3

+ 4    +4                        Do inverse operations by adding 4 on both sides

   x < 1

Therefore, the answer is x < 1.

The circle is open because based on the concept that in inequalities, less/greater than and/or equal to (such as these ≥ ≤ ) signs are graphed with closed circles, while less/greater than (like these > <) signs are graphed with open circles. The direction of the arrow is moving to the left on the number line because all possible values for x would be less than 1. When graphing the inequality you would use a solid line rather than a dashed line (I had to improvise since I could not attach an image).

Hey hey!

To figure out the congruence you have to look at the lines and ticks on both triangles.

So when it gives you one letter you know it's asking for an angle.

And when it gives you two letters you know it's a segment.

When it gives you three letters you're looking for an angle.

A)

<A = <X

<B = <Z

<C = <Y

B)

AB = XZ

AC = XY

BC = ZY

C)

This one is a little tricky, so when it gives you a three-letter angle you have to look at the 'samwitched' letter, which in this case would be A.

To answer this first you have to figure out what angle corresponds to A which would be X.

And then to answer you could say either YXZ or ZXY as long as the X is in the middle it's okay.

Answer:

94.05 units is the perimeter of this pentagon.

Length of each side in pentagon: 2r × Sin(180/n)

                                 where r is radius and n is number of sides

Using the formula: 2r × Sin(180/n)

                              : 2*16 * sin(180/5)

                              : 18.8 units

Perimeter = 5(18.8) units........5 as we know pentagon has 5 sides

                 = 94.05 units

Answer:

1.67 each bottle Because if u do 36.39-2.99= 33.40divided by 20 =1.67 each bottle

Step-by-step explanation:

Answer:

Step-by-step explanation:

999.99 × x% = 299.99

999.99÷100 × x = 299.99

9.9999 × x = 299.99

9.9999x = 299.99

D.B.S by 9.9999 to make x the subject

9.9999x÷9.9999 = 299.99÷9.9999

x=29.999299993

To the nearest tenth of a percent, x=30

Therefore, x = 30%

Step-by-step explanation:

the slope of a line is its inclination and is expressed as ratio of "y coordinate change / x coordinate change" when going from one point to another on the line.

now, I see 2 "good" points on the chart (I mean by that points with integer coordinates) :

(0, 10)

(20, 100)

so, between these 2 points

x changes by +20 (from 0 to 20).

y changes by +90 (from 10 to 100).

so, the slope is +90/+20 = 9/2
