Each day for the next 4 days, there is a 20% chance of a thunderstorm. Use the simulation shown, where the digits 1 and 2 represent days with a thunderstorm, to estimate the probability of a thunderstorm on at least 2 of the next 4 days. Round your answer to the nearest tenth of a percent if necessary.

Answers

Answer:

It’s 6/1

Step-by-step explanation:

The estimated probability of a thunderstorm on at least 2 of the next 4 days is 6/16, or 0.375, or 37.5% (rounded to the nearest tenth of a percent).

What is probability?

Probability is the measure of the likelihood of an event occurring. It is expressed as a number between 0 and 1, with 0 indicating that the event is impossible, and 1 indicating that the event is certain to occur.

To estimate the probability of a thunderstorm on at least 2 of the next 4 days, we can use the simulation as follows:

The outcomes with at least 2 thunderstorms are: 112, 121, 122, 211, 212, and 221.Out of the 16 possible outcomes (each day can either have a thunderstorm or not), the number of outcomes with at least 2 thunderstorms is 6.Therefore, the estimated probability of a thunderstorm on at least 2 of the next 4 days is 6/16, or 0.375, or 37.5% (rounded to the nearest tenth of a percent).

Thus, this is only an estimate based on the given probability of a thunderstorm each day, and the actual probability may be different.

Find the area of the smaller sector round to the nearest tenth. Need help fast!!

Answers

The area of the sector is  76. 95 m

How to determine the area of a sector

Using the formula;

Area of  sector of a circle  = /360° (r2)

where r is the radius of the circle

is the angle of the sector

From the diagram,

= 77°

r = 10. 7m

= 3. 142

Substitute into the formula

Area of the sector = 77/ 360° * (3. 142* 10. 7 * 10. 7)

Area of the sector = 0. 2139 * 359. 72

Area of the sector = 76. 95 m

Thus, the area of the sector is  76. 95 m

What is the surface area of the square pyramid, in square inches (Please Help)

Answers

Answer:

220.8 in.²

Step-by-step explanation:

Area of the pyramid = area of the square + 4(area of the triangle)

Area of square = s²

s = 9.2 in.

Area of the square = 9.2² = 84.64 cm²

✔️Area of the 4 triangles = 4(½*bh)

b = 9.2 in.

h = 7.4 in.

Area = 4(½*9.2*7.4) = 136.16 in²

✅Surface area = 84.64 + 136.16 = 220.8 in.²
