Mathematics

Answer:

The correct answers are A, D, and E.

Step-by-step explanation:

The expected probability of the spinner landing on an even number is 50%, or 125 times. However, it lands on an even number 135 times, which is equal to 54%. This is more than expected. The actual probability is the probability after an experiment has been conducted, therefore the actual probability of landing on an odd number is 46%. The expected probability is the probability before an experiment is conducted, so it is 50%. It is equally likely for the spinner to land on an even or odd number, because each spin is an independent event.

I hope this helps!

If a diameter intersects a chord of a circle at a perpendicular, what conclusion can be made? The diameter and the chord are con

yarga [219]

Answer:

The chord is bisected ⇒ 3rd answer

Step-by-step explanation:

* Lets revise some facts in the circle to solve the problem

- A chord in a circle is the segments whose endpoints lie on the

circumference of the circle

- A diameter of a circle is a chord passes through the center of the

circle

- The diameter is the longest chord in the circle

- Any line passes through the center of the circle and perpendicular

to a chord on the circle bisects it

* Lets solve the problem

∵ The diameter of the circle passes through the center of the circle

∵ The diameter intersects a chord of a circle at a perpendicular

∴ The diameter is perpendicular to the chord

∵ Any line passes through the center of the circle and perpendicular

to a chord on the circle bisects it

∴ The diameter bisects the chord

* The chord is bisected

The perimeter of the

beks73 [17]

Step-by-step explanation:

Longest side is between 36 and 18 feet

18 < L < 36

IF longest side were 36 feet, width =0

IF longest side were 18, then width = 18

to be longest L>W L>18. and L can't be as much as 36 to keep width >0

What is the mass of an object that has a density of 1.3 g/cm3 and a volume

tangare [24]

Answer:

The mass of the object is 2.6 grams

Step-by-step explanation:

The density of an object is the ratio between its mass and its volume

The equation of the is d = $\frac{m}{V}$ , where

m is the mass

V is the volume

Let us use this equation to solve the question

∵ An object has a density of 1.3 g/cm³

∴ d = 1.3 g/cm³

∵ Its volume is 2 cm³

∴ V = 2 cm³

→ Substitute them in the equation of the denisty above

∵ 1.3 = $\frac{m}{2}$

→ Multiply both sides by 2

∴ 2 × 1.3 = 2 × $\frac{m}{2}$

∴ 2.6 = m

∴ The mass of the object is 2.6 grams
