Prove that Quadrilateral ABCD is a Rhombus <br> show all the work
Bezzdna [24]

Answer:

Say that the shape is a parallelogram with equal length sides;

AB = CD

ABD = CDB as the bisecting lines (you have drawn) prove ABD : CDB are both isosceles triangles.

Therefore ABD = ADB

Draw the shape's diagonals as each others' perpendicular bisectors;  

Draw the shape's diagonals bisect both pairs of opposite angles.

If two non congruent angles were given in example 70 degree and 110 degree then say M ∴ = (1/2 )(M∴BAD) = 35  =  (1/2 )(M∴BEF) = 35

and do the same for  1/2(M∴ABC) = 55 = 1/2 (M∴CDA) = 55

In a study of parents' perceptions of their children's size, researchers asked parents to estimate their youngest child's height
maks197457 [2]

Answer:

B) TS = -6.51, p-value = 0.0000

Step-by-step explanation:

Sample size, n = 39

μ = 7.5 cm

Null hypothesis, H₀ = 7.5 cm

(I.e. Average height of youngest child is 7.5 cm)

Alternative hypothesis, H_{a}\neq  7.5 (The youngest child's age is underestimated by 7.5 cm)

Standard deviation, \sigma = 7.2 cm

In order to be able to reject the null hypothesis,

the formula for the test statistic:

t = \frac{- \mu}{s/\sqrt{n} }

t = \frac{- 7.5}{7.2/\sqrt{39} }

t = -6.51

P - value

P(x < 7.5) = P(z < -6.51)

Checking the p-value for z < -6.51 in the normal distribution table

P(z < -6.51) = 0.0000

p - value = 0.0000

If you have a square that has sides measuring 5 inches what is the measure of its diagonal​
Oxana [17]

Answer:

5√2 Inches

Step-by-step explanation:

By definition of a square, all it's sides are the same measurement (typically signified by the variable <em>s</em> on all sides).

In a triangle (as with a intersection from one corner to the other (diagonal), It would create a right triangle. Remember, the two leg sides are the same measurement (typically placed as 1). There is one triangle side measurement rule:

1 , 1 , √2

Plug in the corresponding numbers to the corresponding units. the 5 inches is a side (not the hypotenuse), so it belongs in the 1:

1 x 5 = 5

1 x 5 = 5

√2 x 5 = 5√2

The measurement of it's diagonal (hypotenuse) is 5√2.
