A number cube is rolled 12 times and lands on 3 four times and on 5 three times. Find the experimental probability of landing on three.

Answer:

I'm pretty sure it's 21 11/12. Don't get mad if I'm wrong

Step-by-step explanation:

-7 2/3 - 5 1/2 + 8 3/4

= -7 8/12 - 5 6/12 + 8 9/12

12 14/12 + 8 9/12

20 23/12

= 21 11/12

Answer:

[tex]9\pi[/tex], which is approximately [tex]28.26[/tex].

Step-by-step explanation:

Consider two sectors in the same circle. The area of the two sectors is proportional to their central angles. In other words, if the central angle is [tex]\theta_1[/tex] for the first sector in this circle, and [tex]\theta_2[/tex] for the second, then:

[tex]\displaystyle \frac{\text{Area of Sector 1}}{\text{Area of Sector 2}} = \frac{\theta_1}{\theta_2}[/tex].

In this question, think about the whole circle as a sector. The central angle of this "sector" would be [tex]360^\circ[/tex] (a full circle.) Compare the area of this circle to that of the [tex]60^\circ[/tex]-sector in this circle:

[tex]\displaystyle \frac{\text{Area of Circle}}{\text{Area of $60^\circ$-Sector}} = \frac{360^\circ}{60^\circ} = 6[/tex].

In other words, the area of this circle is six times that of the [tex]60^\circ[/tex]-sector in it.

The area of that [tex]60^\circ[/tex]-sector is [tex]\displaystyle \frac{3}{2}\pi[/tex]. Therefore, the area of this full circle will be [tex]\displaystyle 6 \times \frac{3}{2}\pi = 9\pi \approx 28.26[/tex].

Answer:

When finding the value of x let y be 0 and when finding value of y let x be 0 and get your answers.

Answer:

The answer is C.

Step-by-step explanation:

To start off 250g is $1.85 and we want to get to 500g so if we add $1.85 with $1.85 we will get $3.70.  This amount is more than the number if we bought just 500g once than if we bought 250g twice, because if we did, we would be paying more.  But that's not all, if we add 500g with 500g we will get $6.20.  That's more than the original price for 1 kg and if we multiply 250g 4 times than we get 7.4.  So in all we would buy 1 kg.

Answer:

B). -3

add the -1.4 to-3.5 then divide the solution

Answer:

It's B. -3 (please mark as brainliest)

Step-by-step explanation:

0.7x−1.4=−3.5

Step 1: Add 1.4 to both sides.

0.7x−1.4+1.4=−3.5+1.4

0.7x=−2.1

Step 2: Divide both sides by 0.7.

0.7x

0.7

=

−2.1

0.7

So it's x=−3

-9x + x = 17 – 1  

8x = 16

X = 16/8  

X=2

Answer:

14

Step-by-step explanation:

.3a+.8=.5a-2

Subtract. 3a from both sides:

.8=.2a -2

Add 2 to both sides:

2.8=.2a

Multiply both sides by 5:

a=14

Hope this helps!

Answer:

a = 14

Step-by-step explanation:

.3a + .8 = .5a - 2

.3a - .5a = -2 - .8

-.2a = -2.8

a = -2.8/-.2

a = 14

Answer:

C 12 inches

Step-by-step explanation:

you get the circumference formula C = 2 *pi *r

then divide 2 from 75 and then pi and then you get your radius

i hope this helped<3

Step-by-step explanation:

a 38 inches

The radius is half of the circumference.

Now lets figure out what we know.

1.Our circumference is 75 inches

We would have to divide 75 by two to get it in half.

75÷2=37.5

Now we round to the nearest inch.

And our answer is 38 inches (A)

Answer:

1.55s

Step-by-step explanation:

The height equation of the projectile is given as;

h = -16t^2 + vt + s .......1

where;

t is the time in seconds,

v is the upward velocity at the start,

s is the starting height.

Given;

v = 70 ft/s

s = 5 ft

Substituting the values equation 1 becomes;

h = -16t^2 + 70t + 5

For the ball to reach 75 ft, h = 0

75 = -16t^2 + 70t + 5

-16t^2 + 70t + 5 - 75 = 0

-16t^2 + 70t - 70 = 0

solving the quadratic equation;

Time t = 2.83 s and t = 1.55s

Therefore, the ball will first reach 75 ft after 1.55 seconds.

Kono Dio Da!!!!

Answer:

A.) Henry

B.) Thomas

Step-by-step explanation:

Given the following :

Henry's elevation = 10feets relative to sea level

Thomas elevation = -12 1/2 that is (-25/2) feet relative to sea level

Person with greater elevation:

Elevation can be described as height, in this case, the sea level used as the reference point. Therefore, a positive distance denotes an elevation above the reference point (which is the sea level). Therefore, Henry has a greater elevation of 10 feet( a distance above 0).

B) Who is farther from sea level:

This can be calculated by comparing the absolute distance between the elevation of both Henry and Thomas relative to the reference point(sea level)

Take reference point as 0

Absolute distances relative to sea level:

Henry's distance | 10 - 0 | = 10

Thomas's distance | -(25/2)- 0 | = 12 1/2

A then B

m-n = 16

Let n = 8

m-8 = 16

Add 8 to each side

m-8+8 =16+8

m = 24

Answer:

undefined

Step-by-step explanation:

We can find the slope of a line using two points by

m = (y2-y1)/(x2-x1)

   = (-9- -4)/(-4 -  -4)

    = (-9+4)/(-4+4)

   = -5/0

When we divide by zero, our solutions is undefined

The slope is undefined

Answer:

He needs to sell at least 49 mugs.

Step-by-step explanation:

Since Ronny earned $228 and needs to earn more than $372, he needs to earn more than 372-228 = 144.

Since he sells a mug for $3 and needs more than $144, his earning must be greater than 144:

→ 3x > 144, x represents the number of coffee mugs

→ x > 48

→ x must be at least 49

Answer:

8

Step-by-step explanation:

y < mx+c

here  y will be the temperature on any particular winter day, x will be the variable on whixh temperature is dependent  and m will be the gradient.

The temperature must always be less than 8 so c will be 8.

y < 8

8 should be the maximum value of the inequaltiy

Answer:

your anwser is 8

Step-by-step explanation:

The equation of a line is written as y =Mx + b, where m is the slope and b is the y intercept, which is the y value when x = 0.

You are told the slope is -1/4, so replace m with -1/4. You are also given the point (0,0) which means when x is 0, y is also 0, so replace b with 0.

The equation becomes y= -1/4x + 0

Because y is 0 you aren’t adding anything to the equation so you can remove it from the equation.

Answer is y = -1/4x

Probability helps us to know the chances of an event occurring. The probability that the two pieces of fruit are oranges is 3/28.

Probability helps us to know the chances of an event occurring.

[tex]\rm Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}[/tex]

Given that the two pieces of fruit are randomly picked out of a covered basket with 5 apples and 3 oranges. Therefore, the probability that the two pieces of fruit are oranges is,

Probability = (3/8) × (2/7) = 6/56 = 3/28

Hence, the probability that the two pieces of fruit are oranges is 3/28.

Answer:

The answer is A

Step-by-step explanation:

Answer:

The given inequality is

[tex]23m + 4 > 96[/tex]

Where [tex]m[/tex] represents minutes.

A problem that can be modeled by this inequality is:

Lucy earn $23 per minute, with an extra $4 due to punctuality, which must give more than $96 a day so she can make a living with that job. How many minutes does she need to work?

To solve the problem, we just solve the expression for [tex]m[/tex]

[tex]23m +4 > 96\\23m > 96-4\\23m > 92\\m > \frac{92}{23}\\ m > 4[/tex]

Therefore, Lucy needs to work more than 4 minutes in order to make a living with that job.

Answer:

Step-by-step explanation:

interest = Amount - principal

A = P(1+r)^t

r = 5.5% = 5.5/100 = 0.055

A = 1663(1+ 0.055)^19

A = 1663 (1.055)^19

A = 4,599.270812203411

Let’s say A = 4,599

interest = 4,599-1663 = 2,936
