Compare -1.96312… and - square root of -15
Negation of square root is never considered a number while rest any number comes under the category of the Real number
The Numbers here are divided into two categories: Real and Imaginary. In addition to being divided into Rational and Irrational numbers. In the category of rational numbers, fractions and integers fall under the category. The decimal numbers which are unconvertable to the fraction form are known as irrational numbers. This means that here in the question √-15 = 15i(where i = √-1, the imaginary number)
Hence √-15 is not considered a number while -1.96312... comes under the category of a Real Number.

By examining past tournaments, it's possible to calculate the probability that a school wins their
first game in the national college basketball toumament,
Rank 2 5 7 8 9 10
Probability (%) 93 70 63 53 45 42
Each school's rank going into the tournament is a strong indicator of their likelihood of winning
their first game. This can be expressed as y= -6.42x + 105 where x is their rank (out of 16) and
y is the percent chance they have of winning their first game.
Using this model, a school ranked #12 has what probability of winning their first game? Round

The measure of the angle m∠J is 35°.
An angle is a figure in Euclidean geometry made up of two rays that share a common terminal and are referred to as the angle's sides and vertices, respectively. Angles created by two rays are in the plane where the rays are located.
Consider the triangle KJL,
The line KM is perpendicular to the line JL and M is the midpoint of the line JL.
Therefore, the angle KMJ will be equal to 90°.
Now, we have the angle KJM is equal to 55°.
We know the sum of all interior angles of a triangle is 180°.
So,
In triangle JKM,
∠JKM + ∠KJM + ∠KMJ = 180°
∠JKM + 55° + 90° = 180°
Subtracting 90° from each side of the equation.
∠JKM + 55° + 90° - 90° = 180° - 90°
∠JKM + 55° = 90°
Subtracting 55° from each side of the equation.
∠JKM + 55° - 55° = 90° - 55°
∠JKM = 35°

quest
O 1 x 10^4
O 16 x 10^3
O 1.6 x 10^4
O 10 x 103
O 16 x 10^-10
Answer:
1.6 x 10^4
Step-by-step explanation:
First, 8*2 = 16
Since we are using scientific notation, this is expressed as 1.6 * 10^1
When we multiply using scientific notation, we add the exponents, therefore, 10^-2 x 10^5 = 10^3
1.6 x 10^1 x 10^3
We get 1.6 x10^4

Answer: second and fourth choices have infinitely many solutions
Step-by-step explanation:
When you combine the like terms in those two equations you end up with an "identity." Both sides of the equation are the same.
x - 1/3(3x) = 0 . 1/3 of 3x is 1x
x - x = 0 any number minus itself is 0
or add x to both sides x-x+x = 0 + x
x = x is an identity. An identity has infinite solutions.
3x + 2 - 1/3(3x) = 2 + 2x
3x + 2 -x = 2 + 2x
2x +2 = 2 + 2x . same thing! Infinite solutions.

The circumference of a circle is 17π ft. What is the area, in square feet? Express your answer in terms of \piπ.
The answer for this question is 72.25pi
The area of the circle is 72.25π ft².
What is Surface Area?For each three-dimensional geometrical shape, surface area and volume are determined. The area or region that an object's surface occupies is known as its surface area. Volume, on the other hand, refers to how much room an object has.
As per the given data:
circumference of a circle = 17π ft
To find the area of the square:
Area = πR²
For radius (R):
2πR = 17π
R = (17/2) ft
Area = π(17/2)²
= 72.25π ft²
Hence, the area of the circle is 72.25π ft².

Jackie went to the store and bought 2 1/4 pounds of apples at $5 per pound and 9 pounds of pears at $2.35 per pound. If she paid with a $50 bill, how much change did she receive? Hint* USE THE $ SIGN IN YOUR ANSWER. YOUR ANSWER SHOULD HAVE 2 DECIMAL PLACES.
Answer:
$17.60
Step-by-step explanation:
Jackie went to the store and bought 2 1/4 pounds of apples at $5 per pound
1 pounds = $5
2 1/4 pounds = x
x = 2 1/4 × $5
x = 9/4 × $5
x = $45/4
x = $11.25
9 pounds of pears at $2.35 per pound.
1 pound = $2.35
9 pounds = x
x = 9 × $2.35
x = $21.15
Total amount that she spent =
$11.25 + $21.15
= $32.40
If she paid with a $50 bill, how much change did she receive?
The change she received =
$50 - $32.40
= $17.60
