Suppose you flip a coin and spin a spinner that is divided into 8 equal regions. Of the 8 equal regions, 3 are red, 4 are black and 1 green. What is the probability of "tails" on the coin, and the spinner landing on red?
 (Hint: How many spaces are on the spinner total?)Immersive Reader(5 Points)

Answer 1
Answer:

Answer:

18.75%

Step-by-step explanation:

The probability of the coin is 1/2, because it only has two options (tail or head).

Now, in the case of roulette, it has a total of 8 options, and the red region has 3 parts, that is, of the 8 options, roulette 3 is red, therefore the probability is 3/8

Now the final probability is the multiplication of the probability of both events:

(1/2) * (3/8) = 0.1875s 18.75%

In other words, the probability of these two events happening, that the tail comes out and is red, i

a bowling ball is dropped from a height of 24 feet. write a function that gives the height h (in feet) of the bowling ball after t seconds

Answers

Answer:

h=16t^2

Step-by-step explanation:

t = Time taken

u = Initial velocity

v = Final velocity

s = Displacement

a = Acceleration due to gravity = 32 ft/s²

s=ut+(1)/(2)at^2\n\Rightarrow h=ut+(1)/(2)32* t^2\n\Rightarrow h=ut+16t^2

Here, u = 0 so,

h=0t+16t^2\n\Rightarrow h=16t^2

The equation is h=16t^2

24=16t^2\n\Rightarrow t=\sqrt{(24)/(16)}\n\Rightarrow t=1.22\ s

Time taken by the ball to hit the ground is 1.22 seconds
gravity pulls at 32 feet per second so it would take .75sec to hit the ground now make an equation that can make this applicable so after .75 second T it would be at 0 feet H

In the figure below, segment AC is congruent to segment AB.Which statement is used to prove that angle ABD is congruent to angle ACD?
Answer

Angle CAB is congruent to angle CBA.

Angle DAC is congruent to angle DAB.

Triangle ACD is similar to triangle ABD.

Segment AD is congruent to segment AC.

Answers

Answer:

Option B is correct.

Angle DAC is congruent to angle DAB

Step-by-step explanation:

Given: Segment AC is congruent to segment AB.

In  ΔABD and ΔACD

AB \cong AC    [Given]

[Congruent sides have the same length]

AB = AC         [Side]

AD = AD        [Common side]

\angle DAC =\angle DAB      [Angle]

Side Angle Side(SAS) Postulate states that if two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then the two triangles are congruent.

Then by SAS,

\triangle ABD \cong \triangle ACD

By CPCT [Corresponding Parts of congruent Triangles are congruent]

then;

\angle ABD \cong \angle ACD

therefore, only statement which is used to prove that angle ABD is congruent to angle ACD is: Angle DAC is congruent to DAB
The right answer for the question that is being asked and shown above is that: "Angle DAC is congruent to angle DAB." The statement that is used to prove that angle ABD is congruent to angle ACD is that Angle DAC is congruent to angle DAB.

Let p ( n ) and s ( n ) denote the product and the sum, respectively, of the digits of the integer n . For example, p ( 23 ) = 6 and s ( 23 ) = 5 . Suppose N is a two-digit number such that n = p ( n ) + s ( n ) . What is the unit digit of n ?

Answers

Let's consider a two-digit number N where the sum of its digits is s(N) and the product of its digits is p(N). According to the given condition:

N = p(N) + s(N)

We know that the largest possible product of two single-digit numbers is 9, which occurs when both digits are 9. Therefore, p(N) ≤ 9.

The largest possible sum of two single-digit numbers is 18, which occurs when both digits are 9. Therefore, s(N) ≤ 18.

Now, let's find the unit digit of N. Since we are looking for the unit digit, we need to consider the possible values of p(N) and s(N) that result in a unit digit for N.

1. If p(N) = 9 (the maximum value for the product of two digits) and s(N) = 9 (the maximum value for the sum of two digits), then N = 9 + 9 = 18. In this case, the unit digit of N is 8.

2. If p(N) = 1 (the minimum value for the product of two digits) and s(N) = 1 (the minimum value for the sum of two digits), then N = 1 + 1 = 2. In this case, the unit digit of N is 2.

So, the possible unit digits for N are 2 and 8, depending on the values of p(N) and s(N).
