HELP!! Which of the following is not a possible value for a probability?
A. 0.001
B. 1/16
C. 0.82
D. 5/4

Answers

Answer: Option 'D' is correct.

Step-by-step explanation:

Since we know that

Probability is the giving the possibility of given outcome or any certain events.

Probability is the number of ways of achieving the success.

Probability of event that certain to happen is 1.

Probability of event that is impossible is 0.

Sum of probabilities of all likelihood occurring events is 1.

So, Probability of any event can exceed 1.

But,

[tex]\frac{5}{4}=1.25\text{ which is greater than 1}\\[/tex]

Hence, it is not possible value for a probability .

Therefore, Option 'D' is correct.

Final answer:

The value 5/4 is not a valid probability, as probabilities must be between 0 and 1 inclusive. The correct answer is D.

Explanation:

The question that needs assistance asks about which value is not a possible value for a probability. By definition, probabilities can range from 0 (the event will not occur) to 1 (the event is certain to occur). So, looking at the options given, A (0.001), B (1/16), and C (0.82) are all between 0 and 1, which means they are valid probabilities. However, option D (5/4) is greater than 1, which makes it an invalid probability. The correct answer is D: 5/4 is not a possible value for a probability.

How many times does the graph of the function below intersect or touch the x-axis? y=-3x^2+x+4 ...?

Answers

when the graph touches x axis at that point y = 0

 So, putting y =0
  0 = -3x^2 + x +4
so, if you factoriazte it

−3x^2++4x−3x+4=0

−3x(x+1)+4(x+1)=0

(x+1)+(−3x+4)=0

x=−1,4/3

Find the zeros of g(x)=x2+5x−24g

Answers

I'll assume the 'g' at the end is a typo and shouldn't be there. Set the right side equal to zero and solve for x

x^2+5x-24 = 0

(x+8)(x-3) = 0

x+8 = 0 or x-3 = 0

x = -8 or x = 3

The zeros or roots are x = -8 or x = 3
❀Hm, I'm pretty sure you should solve for g. If so, then the first step we would need to do is add 24g to both sides:
gx+24g=x^2−24g+5x+24g
gx+24g=x^2+5x
❀Now you are going to factor out variable g:
g(x+24)=x^2+5x
❀Finally divide both sides by x+24:
[tex] \frac{g(x+24)}{x+24 } = \frac{x^2+5x }{x+24 } [/tex]

❀Your answer is:
[tex]g= \frac{x^2+5x }{x+24 } [/tex]

Lynn and dawn tossed a coin 60 times and got heads 33 times what is the experimental probability of tossing heads using Lynn and dawns results

Answers

Answer: Experimental probability of tossing head is [tex]\frac{11}{20}[/tex]

Step-by-step explanation:

Since we have given that

Number of times Lynn tossed a coin = 60 times

Number of times head comes = 33

Experimental probability of tossing heads using Lynn and drawn results is given by

[tex]\frac{\text{Number of favourable outcomes}}{\text{Total number of outcomes}}\\\\=\frac{33}{60}\\\\=\frac{11}{20}[/tex]

Hence, Experimental probability of tossing head is [tex]\frac{11}{20}[/tex].

Answer:

experimental probability of tossing heads using Lynn and dawns results is [tex]\frac{11}{20}[/tex].

Step-by-step explanation:

Given :Lynn and dawn tossed a coin 60 times and got heads 33 times

To find : what is the experimental probability of tossing heads using Lynn and dawns results.

Solution : We have given that  

Number of times Lynn tossed a coin = 60 times.

Number of times head comes = 33.

 Probability of tossing heads using Lynn and drawn results is given by:

  = N[tex]\frac{number of favouable outcome }{total possible outcome}[/tex]

= [tex]\frac{33}{60}[/tex].

On simplification

=[tex]\frac{11}{20}[/tex].

Therefore, experimental probability of tossing heads using Lynn and dawns results is [tex]\frac{11}{20}[/tex].

59 pounds to 35 pounds increase or decrease

Answers

If you went from 59 pounds to 35 pounds, that's a 24 pound decrease
Final answer:

Comparing 59 pounds to 35 pounds shows a decrease of 24 pounds, which can be calculated by subtracting the smaller number from the larger number.

Explanation:

If we are considering the transition from 59 pounds to 35 pounds, we need to determine whether this change represents an increase or a decrease. Comparing the two numbers, we can observe that 35 pounds is less than 59 pounds. Therefore, moving from a higher number to a lower number indicates a decrease. To calculate the decrease, we subtract the smaller number (35 pounds) from the larger number (59 pounds) which equals 24 pounds. So, there is a decrease of 24 pounds.

Using the example parameters given in the hypothetical experiment on weight perception, we've applied similar reasoning. If someone in the experiment stepped down from lifting 20 pounds to lifting weights less than this, it would also be considered a decrease in weight. If they stepped up from lifting a weight of 20 pounds to a heavier weight, it would be termed an increase. This example underscores the importance of difference detection, which is often studied in sensory experiments within psychology.

Find the dimensions of a right-circular cylinder that is open on the top and closed on the bottom, so that the can holds 1 liter and uses the least amount of material? ...?

Answers

Volume of cylinder:
V = πr²h
The desired volume is 1 Liter = 1000 cm³
1000 = πr²h
h = 1000/πr²

Surface area of cylinder:
S.A = 2πr² + 2πr²h
We substitute the value of h from the first equation:
S.A = 2πr² + 2πr(1/πr²)
S.A = 2πr² + 2/r
Now, to minimize surface area, we differentiate the expression with respect to r and equate to 0.
0 = 4πr - 1000/r²
4πr³ - 1000 = 0
r = 4.3 cm
h = 17.2 cm
Final answer:

The dimensions of the right-circular cylinder, which has a volume of 1 liter and uses the least amount of material, are such that the radius and twice the height are equal to the cube root of the volume divided by π, i.e., (0.001/π)^(1/3).

Explanation:

In Mathematics, given the volume of a right-circular cylinder (an open top can), we can find its optimal dimensions that would use the least amount of material. These dimensions correspond to the minimum surface area of the cylinder, which includes its closed bottom but not the open top.

Since the volume V of a right-circular cylinder is given by V=πr²h, where r is the radius and h is the height. We know that the volume equals 1 liter or 0.001 m³. Rearranging the volume equation for h gives us h=V/(πr²).

Next, the surface area A of the cylinder with closed bottom is A=2πrh+πr². Substituting h=V/(πr²) into the surface area gives A=2r(V/r)+(πr²) which simplifies to A=2V/r+πr². For the surface area to be minimum, the derivative of A with respect to r must be equal to zero. The first derivative of A is A'=-2V/r²+2πr. Set A'=0 we solve for r we find r=(V/(π))^(1/3). Substituting this value back into the equation for h gives us h=2*(V/(π))^(1/3).

Hence, for a right-circular cylinder of 1 liter volume (0.001 m³) to use the least amount of material, it should have a radius and twice the height equal to the cube root of the volume divided by π, i.e., (0.001/π)^(1/3).

To convert from radical form to rational exponent form, use [tex]\( \sqrt[n]{a} = a^{1/n} \),[/tex] and vice versa for conversion.

An expression written in radical form can be rewritten in rational exponent form and vice versa using the following conversions:

1. From Radical Form to Rational Exponent Form:

  - For a radical expression [tex]\( \sqrt[n]{a} \), where \( n \)[/tex] is the index and [tex]\( a \)[/tex] is the radicand:

  - The equivalent expression in rational exponent form is [tex]\( a^{1/n} \)[/tex].

2. From Rational Exponent Form to Radical Form:

  - For an expression [tex]\( a^{m/n} \)[/tex], where [tex]\( a \)[/tex] is the base, [tex]\( m \)[/tex] is the numerator, and [tex]\( n \)[/tex] is the denominator:

  - The equivalent expression in radical form is [tex]\( \sqrt[n]{a^m} \).[/tex]

These conversions allow us to switch between radical form and rational exponent form easily. It's important to remember that the index of the radical corresponds to the denominator of the rational exponent, and the exponent of the base corresponds to the numerator of the rational exponent.

Final answer:

One million days from now would be roughly the year 3759 AD. The exact day and month would fall sometime in March or April due to the complexities of our modern calendar system.

Explanation:

To answer your question of what is the day 1,000,000 days from now, we'll need to do some calculations. There are approximately 365.25 days in a year (this includes the extra day every four years for leap years).  

1,000,000 divided by 365.25 equals approximately 2737.85 years. This means that 1,000,000 days from now it would be the year 3759 AD (assuming the current year is 2022).

As for the exact day, we'll consider that a year is made up of 365 days, and the .25 accounts for leap years. However, the calculation of the exact date and month is quite complex due to the irregularities in our Gregorian calendar. It would fall sometime in March or April of 3759 AD.

Note that this calculation does not consider minute changes in Earth's rotation over time or potential changes in our calendar system.

= approximately 17.0 feet

Hope this helps

Answer:

C. 17.0 feet

Step-by-step explanation:

We have been given that Jacob kicks a soccer ball off the ground and in the air with an initial velocity of 33 feet per second. We are asked to find the maximum height the soccer ball using formula [tex]H(t)=-16t^2+vt+s[/tex].

First of all, we will substitute [tex]v=33[/tex] in our given formula.

[tex]H(t)=-16t^2+33t+0[/tex]

Since our given parabola has a negative leading coefficient, so it will be downward opening parabola. The maximum height of the ball will be y-coordinate of the vertex of parabola.

Let us find x-coordinate of parabola as:

[tex]\frac{-b}{2a}=\frac{-33}{2\times -16}=\frac{-33}{-32}=\frac{33}{32}[/tex]

Now, we will substitute [tex]x=\frac{33}{32}[/tex] in our formula to find y-coordinate of vertex.

[tex]H(\frac{33}{32})=-16(\frac{33}{32})^2+33(\frac{33}{32})+0[/tex]

[tex]H(\frac{33}{32})=-16*\frac{1089}{1024}+\frac{1089}{32}[/tex]

[tex]H(\frac{33}{32})=-16*1.0634765625+34.03125[/tex]

[tex]H(\frac{33}{32})=-17.015625+34.03125[/tex]

[tex]H(\frac{33}{32})=17.015625[/tex]

[tex]H(\frac{33}{32})\approx 17.0[/tex]

Therefore, the ball reached the maximum height of 17.0 feet and option C is the correct choice.
