Given that x is a nonnegative number, a student conjectured that x + 3 < x2.
nadya68 [22]

Answer:

C (x = 2)

Step-by-step explanation:

Since x is a non-negative number, A and B are eliminated.

This leaves C and D.

C: x = 2,

2 + 3 < 2^2

5 < 4 is false.

So C would be a counterexample.

Hope this helps!

The probability of Elizabeth winning the soccer game is 0.72. What is the probability of not winning the game?
Rom4ik [11]

Answer:

.28 = P( not winning)

Step-by-step explanation:

The probability of winning is .72

The 2 possibilitites are winning and not winning.  They must total 1

1 = P(winning) +P( not winning)

1 = .72 + P( not winning)

Subtract .72 from each side

1-.72 = P( not winning)

.28 = P( not winning)

Determine the coordinates of the corners of the rectangle to compute the area using
inysia [295]

Answer:

77.93

Step-by-step explanation:

#We can simply read off the x,y coordinates directly from the graph.

i. [1,8]\\\\ii. [4,5]\\\\iii. \ [14,21]\\\\iv.\ \ \ [17,18]

#we know that a rectangle has pair of two equal sides. To calculate the area, we determine the dimension of any un-equal  two sides:

#Using Pythagorean Theorem:

\#Use \ ii \ and \ iv \ to \ calculate \ length.\\\\a^2+b^2=c^2\\\\(17-4)^2+(18-5)^2=l^2\\\\l=18.38\\\\\#Use \ i \ and \ ii \ to \ calculate \ width.\\\\a^2+b^2=c^2\\\\(4-1)^2+(8-5)^2=w^2\\\\w=4.24

We can therefore calculate area as:

A=lw\\\\=18.38\times 4.24\\\\=77.93

Hence, the area of the rectangle is 77.93
