The mean proportion is p = 4/35 = 0.1143, q = 1 - p = 0.8857, and sample of n = 35.
For a 95% CI, z = +/-1.96
The Agresti-Coull method is as follows:
Limits = [p + (z^2 / 2n) + z*sqrt(pq/n + z^2 / 4n^2)] / (1 + z^2 / n)
Using this formula, the lower limit is 0.0454, while the upper limit is 0.2595.

Look at this set of ordered pairs: (14, 19) (14, 5) (4, 18) Is this relation a function? yes no​
Vitek1552 [10]

Answer:

This is a relationship, and NOT a function

Step-by-step explanation:

Notice that from the pairs listed, we find that the number 14 in the Domain is connected via the relationship with TWO different numerical values in the Range (with 19 and with 5).Therefore, this cannot be a function, since in such case, each element of the Domain must connect with no more than one element of the Range.

d=√(-4+2)^2 + (2+5)^2

d=√(4+49)

d=√53

Let me know if this helps!

•given ABCD is a kite, check every box that must be true
natali 33 [55]

Answer:

Step-by-step explanation:

A kite is a quadrilateral made up of two isosceles triangles. A kite does not have any parallel side, but has two pairs of equal adjacent sides. All four sides are not congruent, only two pairs of consecutive sides are congruent.

The vertices of a kite are right angles. The diagonals bisect each other at right angles ( that is they are perpendicular). Therefore the following are true:

1) two pairs of consecutive sides are congruent

2) The diagonals are perpendicular

3) The diagonals bisect each other.

Point A= (3,6), B = (5,0), C= (-2,-4) D = (-3,4)

AB=\sqrt{(0-6)^2+(5-3)^2}=\sqrt{40}  \\AD=\sqrt{(4-2)^2+(-3-3)^2}=\sqrt{40}\\ BC=\sqrt{(-4-0)^2+(-2-5)^2}=\sqrt{65}\\  DC=\sqrt{(4-(-4)^2)+(-3-(-2))^2}=\sqrt{65}

AB=AD, BC = BC.

This is a kite since two pairs of consecutive sides are congruent

Multiply: (-5qr) × (-2pqr) × pq​
ahrayia [7]

Answer:

The product of (-5·q·r) × (-2·p·q·r) × p·q is 10·q³·r²·p²

Step-by-step explanation:

The question relates to the rules of multiplication of variables and indices rules, and simplifification of an expression ;

The given expression is (-5·q·r) × (-2·p·q·r) × p·q

Therefore, we have;

(-5·q·r) × (-2·p·q·r) × p·q = (-5) × (-2) × q×q×q × r×r ×p×p = 10 × q³ × r² × p²

10 × q³ × r² × p² = 10·q³·r²·p²

∴ (-5·q·r) × (-2·p·q·r) × p·q = 10 × q³ × r² × p² = 10·q³·r²·p²

(-5·q·r) × (-2·p·q·r) × p·q = 10·q³·r²·p².
