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

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.

I hope this helps a bit :)

Answer:

Whole number is  16

Step-by-step explanation:

Whole number are 0,1,2,3,........

Answer:

16!

-8 is the absence of number

0.23 isn't a full number neither is 4/5 and 2.54

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

Answer:

$2,889.06

Step-by-step explanation:

First, convert R as a percent to r as a decimal

r = R/100

r = 7.5/100

r = 0.075 rate per year,

Then solve the equation for A

A = P(1 + r/n)nt

A = 2,500.00(1 + 0.075/1)(1)(2)

A = 2,500.00(1 + 0.075)(2)

A = $2,889.06

Summary:

The total amount accrued, principal plus interest, with compound interest on a principal of $2,500.00 at a rate of 7.5% per year compounded 1 times per year over 2 years is $2,889.06.

I don't think I need to explain it, the answer is $111

Answer: $111

Step-by-step explanation:

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]

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

Answer:

52

Step-by-step explanation:

Answer:

x = 6.4

Step-by-step explanation:

Set up using proportion and cross multiply to solve:

8/10 = x/8

x = 6.4

Answer:

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).
