Mathematics

Mazyrski [523]3 years ago
4 0

Answer:

Step-by-step explanation:

The function is f(x) = -4x²+10x-8

Let Δ be our the dicriminant

  • Δ= b²-4ac
  • b = 10
  • a = -4
  • c = -8
  • Δ = 10²-4*(-4)(-8)
  • Δ = 100-128
  • Δ = -28

The value of the discriminant is -28 and since it is negative this function has no real zeroes

A quadrilateral has exactly one right angle and two nonadjacent angles that each measure 105 degrees
LiRa [457]

Answer:

C) Kite

Step-by-step explanation:

The problem states that the polygon is a quadrilateral, meaning it has 4 sides. This rules out D, as pentagons have 5 sides. Our next clue is that this shape has <em>only one </em>right angle, ruling out A and B, because, by definition, rectangles and squares must have four 90 degree angles. We can already see that we are left with only one choice, but to confirm: a kite has 2 opposite angles of 105 degrees, like the problem states.

Therefore, the answer is C) Kite

Hope this helps!

cricket20 [7]

The standard deviation is a better measure of spread for movies than it is for basketball games.

<h3>What is box- plot?</h3>

A box plot is a graphical rendition of statistical data based on the minimum, first quartile, median, third quartile, and maximum.

As, Movies is more centric to mean and not skewed on a particular side whereas basketball games is not centric to mean but is skewed right then left.

Now, Standard deviation just measures the deviation or spread with respect to mean of collected data.

So, In the movies the data is more collected. Thus standard deviation is best suited for movie data.

Now, interquartile range. IQR relies on if the data is skewed.

So, in the basketball data the standard deviation will not give the information.

Hence, the  standard deviation is a better measure of spread for movies than it is for basketball games.
