4. 1 less than twice the square of a number
givi [52]

Answer:

2(x^2)-1

Step-by-step explanation:

The square of a number is just the number squared. We don't know what the number is so I will just say it is x. So we have 2 times x^2. Then we have to minus 1 from that. So 2(x^2)-1.

Hope this helps! :D

Select the correct answer from the drop-down menu. a coin is biased to display heads 75% of the time. it is tossed 20 times, and
ella [17]

The most improbable simulation for this coin is the heading when a coin is tossed 20 times will be 15.

<h3>What is probability?</h3>

Probability means possibility. It deals with the occurrence of a random event. The value of probability can only be from 0 to 1. Its basic meaning is something is likely to happen. It is the ratio of the favorable event to the total number of events.

A coin is biased to display heads 75% of the time.

It is tossed 20 times, and the outcomes are recorded.

Then the probability of getting heads when a coin is tossed 20 times. Then we have

\rm P = 0.75 \times 20 = 15

More about the probability link is given below.

Degrees Celsius can be converted to degrees Fahrenheit by multiplying 1 and 4/5 and adding 32 degrees C what is 15 degrees C in
Alexxx [7]

Answer:

15C is 59F

Step-by-step explanation:

As an equation, F = (1 4/5)C + 32. 1 and 4/5 is the same as 9/5.

Substitute 15 for C.

F = (9/5)C + 32

F = (9/5)(15) + 32   Multiply 15 by the top number in 9/5

F = 135/5 + 32       Convert 32 to a fraction over 5

F = 135/5 + 160/5     Add the numerators under the same denominator

F = 295/5        Divide

F = 59              Degrees in Farenheit

Therefore 15°C is 59°F.
