The probability of getting a prime number ( 2, 3, 5, 7) between 1 to 8 is 1/2. The total outcomes possible for spinning the spinner and tossing the coin is 16.

<h3>What is probability?</h3>

Branch of mathematics concerning numerical descriptions of how likely an event is to occur is called probability.

Total number of outcomes = 8.

Let, the probability of getting a prime number ( 2, 3, 5, 7) between 1 to 8

P(E) = (no. of outcomes) /( total no. of outcomes)

=4/8

=1/2

When a coin is tossed,  there are two possible outcomes that are H(head), and T(tail).

If you spin the spinner , there are 8 possibilities.

Total outcomes = 8 * 2

=16

There are 16 outcomes, when spinning a spinner numbered from 1 to 8 and tossing a coin.

Explain how the global sea surface temperature is affected by solar activity.
Dahasolnce [82]
The higher the solar activity, and the hotter it is, the more the oceans heat up and water evaporates into the atmosphere. High amounts of water vapor causes things like hurricanes. However, oceans have a high absorption rate of heat so they can absorb a lot of it without heating up the atmosphere, which is pretty good or else the Earth would overheat.

An alien from the newly discovers planet nine weighs himself on his planet and finds his weight to be 3200 N. When he stoves on
White raven [17]

Answer:

2.45 m/s²

Explanation:

From the question,

On the Earth

W = mg.................. Equation 1

Where W = weight of the alien on the earth, m = mass of the alien on the earth, g = acceleration due to gravity of the earth.

Make m the subject of equation 1

m = W/g................... Equation 2

Given: W = 3200 N

Constant: 9.8 m/s²

Substitute these value into equation 2

m = 3200/9.8

m = 326.5 kg.

Similarly,

On planet 9,

W' = mg'............... Equation 3

Where W' = weight of the alien on planet 9, g' = acceleration due to gravity on planet 9.

make g' the subject of the equation

g' = W'/m............ Equation 4

Given: W' = 800 N

Substitute into equation 4

g' = 800/326.5

g' = 2.45 m/s²

What are the directions of movement for the Sagittarius, frontal, transverse planes ?
Dima020 [189]

Answer:

Squats involve flexion (forward motion) and extension (backward on the way up), so would fit into the sagittal plane. Frontal plane motion would include leaning from left to right as in sidebends and lateral raises, or perhaps you might picture jumping jacks for a good image of movement along the frontal plane.

Agata [3.3K]

Answer:

The environmental conditions prevent the reaction to be accurate.

Explanation:

If the temperature is very hot then the oxygen production will be low even near to zero then the accurate light intensity can not be determined. The oxygen production level goes down when the temperature is too hot. The oxygen production is maximized when the temperature is around 25 degree Celsius. When the intensity of light is increased to 40% then the oxygen production will increase.

allochka39001 [22]

Answer:

325 m/s

Explanation:

The velocity of waves is given as the product of wavelength and frequency of the waves. This is expressed as s=fw where s is the speed, f is frequency and w is wavelength.

Sometimes, when provided with period, you get frequency as the reciprocal of period.

In this case, since the wavelength is given as 0.013 m and frequency as 25000 then we substitute them into the equation of speed as

S=25000*0.013=325 m/s

Therefore, the speed is 325 m/s
