Step-by-step explanation:

a fair number cube has six sides so if you roll that 30 times that's 180 sides and the probability of rolling a 2 out of a single dice is 1/6 and since 180 * 1/6 is equal to 30 that is 30 out of 180 which is 1/6

Answer:

40 times

Step-by-step explanation:

To figure this out, divide 6 by 30, then multiply by 200

(6/30)200 = 40

This also works: (200/30)6 = 40

We divide 6 by 30 because we landed on the 1 side 6 times out of 30. We then multiply 6/30 by 200 because it is out of 200 this time, so we will multiply 6 by 200 then divide by 30. 200(6) = 1200. 1200/30 = 40.

Answer:

Step-by-step explanation:

Two events are independent if the result of the second event is not affected by the result of the first event. If A and B are independent events, the probability of both events occurring is the product of the probabilities of the individual events.

Answer:

scale factor = 2.5 and b` is now (0,10) and c` is (-15, 25)

Step-by-step explanation:

You first want to divide -15 and -6, the x values of a and a`. this will give you the scale factor. then multiply every other number by the scale factor to get the points for b` and c`.

Answer:

The square root of 18 with one digit decimal accuracy is 4.2.

Step-by-step explanation:

Answer:

4.24 (nearest hundredth)

Step-by-step explanation:

Step 1

Square numbers: 1, 4, 9, 16, 25, 36, ...

Find the perfect squares either side of 18:

As [tex]\sf \sqrt{16}=4[/tex] and [tex]\sf \sqrt{25}=5[/tex] then [tex]\sf 4 < \sqrt{18} < 5[/tex]

Step 2

Divide 18 by one of the two square roots in step 1 (4 or 5):

⇒ 18 ÷ 4 = 4.5

Step 3

Find the average of the root (4) and the result (4.5):

[tex]\sf \implies \dfrac{4+4.5}{2}=4.25[/tex]

Repeat steps 2 and 3:

Divide 18 by the solution of step 3.  Then find the average of this and the solution of step 3:

⇒ 18 ÷ 4.25 = 72/17

[tex]\sf \implies \dfrac{4.25+\frac{72}{17}}{2}=\dfrac{577}{136}=4.242647059[/tex]

Repeat:

⇒ 18 ÷ 577/136 = 2448/577

[tex]\sf \implies \dfrac{\frac{577}{136}+\frac{2448}{577}}{2}=4.242640687[/tex]

As the approximate square root needs to be to the nearest hundredth, we do not need to keep repeating the steps.

Therefore, √18 ≈ 4.24 (nearest hundredth)

Answer:

p = (4 × 2401) × 121 = ( 9604 × 121) = 1162084

q = (9 × 125) × 14641 = (1125 × 14641) = 16471125

LCM of 1162084 = 2324168 , 3486252 , 4648336 , 5810420 , 6972504

LCM of 16471125 = 32942250 , 49413375 , 65884500

Blank 1: variability

Blank 2: median

Blank 3: mean

Step-by-step explanation:

p=7500*100=750000

t=6yrs

r=6%

I=p*t*r/100

=750000*6*6/100

=270000

=270000/100

=$2700

Answer:

haiii i can only solve for the vertex...

Step-by-step explanation:

so to find the vertex you have to make it to

y - h = a(x - k)^2

i think

(you could also just make it y = a(x - k)^2 + h but i like the second one better)

soo

y + 5 = 3(x + 7)^2

the vertex is

(-7, -5)

and ummm i think the axis for the axis of symmetry .ss

x = 2a/b but im not sure

Answer:

She should get $12.17 in change.

Step-by-step explanation:

20- 2.25 = 17.75

17.75 - 4.39 = 13.46

13.46 - 1.19 = 12.17

Answer:

40.5 cm²

Step-by-step explanation:

To find the triangles area on the tip of the crayon you do base x height ÷ 2 so 3 x 2 ÷ 2 = 3.

After, multiply 12.5 by 3 then add them both together to get 40.5 cm²

Answer:

0.15

Step-by-step explanation:

Area = [tex]\pi[/tex][tex]r^{2}[/tex]

Area of the shaded region = [tex]\pi 5^{2}[/tex]

Area = 78.5 [tex]in^{2}[/tex]

Area of the whole dart board = [tex]\pi r^{2}[/tex]

Area = [tex]\pi 13^{2}[/tex]

Area = 530.66[tex]in^{2}[/tex]

Probability = [tex]\frac{78.5}{530.66}[/tex]

= 0.1479 ≈ 0.15

Answer:

363

Step-by-step explanation:

[tex]A = \pi r^2[/tex]

it says π is 3

so,

[tex]A = 3r^2[/tex]

r is the radius of the circle which is shown as 11

so,

[tex]A = 3*(11)^2[/tex]

Solve for A

[tex]A= 3* 121\\A= 363[/tex]

Answer:

Step-by-step explanation:

The correct solving of the decimal shows that 3.675 × 10 = 36.750, 3.675 × 100 = 367.5 and 3.675 × 1,000 = 3675.

How to solve the decimals?

From the information given, it should be noted the students calculations are incorrect. Therefore, 3.675 ×10 = 3.6750, 3.675 × 100 = 3.67500 and 3.675 × 1,000 = 3.675000 are incorrect.

In this case, when multiply by raise to power 10, it's important to shift the decimal based on the number being raised to power.

Therefore, 3.675 × 10 = 36.750, 3.675 × 100 = 367.5 and 3.675 × 1,000 = 3675.

Answer:

No, the car didn't catch the bus, as their time and distance traveled doesn't intersect when portrayed on a graph.

Step-by-step explanation:

It would take the car approximately 2.14 hours to catch up to the bus. Since the car left at 12:15 pm, it should have caught up to the bus at 2:29 pm.

Average speed is calculated by dividing a quantity by the time required to obtain that quantity. Meters per second is the SI unit of speed. The formula S = d/t, where S is the average speed, d is the total distance, and t is the total time, is used to determine average speed.

Yes, the car was able to catch up to the bus before it reached the game. With the car travelling at 54 mph and the bus travelling at 48 mph, the car is travelling 6 mph faster than the bus. In order to calculate how long it would take for the car to catch the bus, we use the formula for average speed:

Average speed = (speed of car + speed of bus) / 2

Average speed = (54 mph + 48 mph) / 2

Average speed = 51 mph

Now, we can use the formula for distance travelled over time to calculate how long it would take the car to travel the 110 miles to the game:

Distance = Rate x Time

110 miles = 51 mph x Time

Time = 110 miles / 51 mph

Time = 2.14 hours

Therefore, it would take the car approximately 2.14 hours to catch up to the bus. Since the car left at 12:15 pm, it should have caught up to the bus at 2:29 pm.

Answer:

The first stpe in solving this system of equations is finding either X or Y in terms of the other variable. Ex: x = 8 - y or y = 8 - x

Step-by-step explanation:

When faced with a system of equations problem, you need to find one variable at a time. To do this, you need to eliminate one of the variables from one of the equations. I used x + y = 8 because that was simplier to find one of the variables from. From there, you can substitute that in for the variabel in the secone equation.

3x - 2y = -6

3x - 2(8 - x) = -6

3x - 16 + 2x = -6

5x - 16 = -6

5x = 10

x = 2

Than you can use that and plug it back into one of the original equations to find the other variable.

x + y = 8

2 + y = 8

y = 6
