Answer:

The line segments cross at right angles
AD = AE = CD = CE
The figure ADCE is a rhombus
∠DAE = ∠DCE
∠ADC +∠DAE = ∠ADC + ∠DCE = 180°
∠AEC + ∠DAE = ∠AEC + ∠DCE = 180°
∠ADC = ∠AEC
AD║CE
AE║CD
AC bisects angles A and C
DE bisects angles D and E

Step-by-step explanation:

A rhombus is a quadrilateral that has diagonals that bisect each other. Anything you can say about the angles and segments of a rhombus can be said about the angles and segments of the figure created by these mutual perpendicular bisectors.

A rhombus has 4 equal-length sides. Opposite sides are parallel, and opposite angles are congruent. Adjacent angles are supplementary. Each diagonal bisects the angles at either end.

A house that you are interested in has the following facts listed online: Price = $214,000 APR = 1.15% Down Payment must be 9.5%

gizmo_the_mogwai [7]

9514 1404 393

Answer:

$20,330 down
$193,670 loan
$560.35 monthly
$255,677 total price

Step-by-step explanation:

a) The down payment is 9.5% of the price, so is ...

down = 0.095×$214,000 = $20,330

b) The amount of the loan is the remaining value after the down payment is made:

$214,000 -20,330 = $193,670

c) The monthly payment is given by the amortization formula:

A = P(r/12)/(1 -(1 +r/12)^(-12t))

payment on Principal P at interest rate r for t years

A = $193,670(0.0115/12)/(1 -(1 +0.0115/12)^(-12·35)) ≈ $560.35

d) The total cost of the house is ...

down + (monthly payment)×(number of months)

= $20,330 + $560.35×420

= $255,677

A survey of 1,000 men and women asked, "Do you earn over $50,000 per year?" The table below shows the responses for males and fe

Effectus [21]

Based on the data, it is found that "being female" and "earning over $50,000" are not independent events. the correct answer is option D.

<h3>What is probability?</h3>

Probability is defined as the ratio of the number of favorable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.

Two events, A and B are independent, if:

P(A $\cap$ B) = P(A) P(B)

In this problem, the events are:

Event A: Being female.
Event B: Earning over $50,000.

Out of the 1000 people, 450 are female, hence:

P(A) = $\dfrac{450}{1000}$ = 0.45

850 earn over $50,000, hence:

P(B) = $\dfrac{850}{1000}$ = 0.85

375 are women who earn over $50,000, hence:

P(A $\cap$ B) = $\dfrac{375}{1000}$ = 0.375

The multiplication of the probabilities is:

P(A $\cap$ B) = 0.45(0.85} = 0.3825

Therefore based on the data, it is found that "being female" and "earning over $50,000" are not independent events. the correct answer is option D.

On each task card, there are four statements. Three are correct and one is INCORRECT. Find the incorrect statement and give the

Mrac [35]

Answer:

Statement 4 is incorrect.

Step-by-step explanation:

#4 is incorrect. This statement is assuming that both 3x+5 and 4x are equal, but the correct way to use them and achieve 180 (definition of supplementary) degrees is by writing it as: 3x+5 + 4x = 180. (I spaced the 3x+5 and 4x to make it clear that these are two angles added together.) With this equation, you will be able to find the x and the substitute it back in to complete the equation.
