I’m not sure if this is right but I tried...

The Equation you are going to use: P(event)=number of favorable outcomes/total number of possible outcomes

1. Equal to
The probability of rolling a 4 is 1/6. There is 1 favorable outcome and 6 possible outcomes. The frequency of rolling a 4 after 90 times is 15/90 which is equal to 1/6. Therefore equal to.

2. Greater than
The probability of rolling a number less than 4 is 3/6 or 1/2. After 90 times, the outcome was 46/90 which simplified is 23/45. Half of 45 is 22.5 and 23 > 22.5.

3. Less than
The probability of rolling a multiple of 3 is 2/6 or 1/3. After rolling the cube 90 times, the outcome was 24/90 which simplified is 4/15. 1/3 of 15 is 5. 4 < 5. Therefore, less than.

Hope this helps!!!!

Biologists have found that the number of chirps some crickets make per minute is related to temperature. the relationship is ver
aalyn [17]

Answer:

It is 74.24 degrees Fahrenheit when the crickets are chirping 150 times a minute.

Variables x = Chirps and  y = Degrees

y-intercept = 38.24

slope = 0.24

Step-by-step explanation:

As the chirps are 124 times per minute for 68 degrees Fahrenheit we will consider it in (x_1,y_1) = (124,68).

Now when the chirps are 172 times and temperature is 80 degrees we consider it (x_2,y_2) = (172,80).

To find the slope we can use point-slope formula.

Where m is the slope and m=\frac{y_2-y_1}{x_2-x_1} =\frac{80-68}{172-124}= 0.24

To find y-intercept we will plug out the value of slope in y=m(x)+b choosing point (x_1,y_1) = (124,68).

So b=y-m(x) =68-124(0.24) =68-29.76=38.24

And the equation is y=0.24(x)+b

To calculate temperature for 150 chirpings we have to plug x=150 and b=38.24 in our above equation which is in form of y=m(x)+b

y=0.24(x)+b

y=0.24(150)+38.24=74.24\approx 75 degrees Fahrenheit.

Finally we have :

Temperature 74.24 degrees Fahrenheit.

With variables x = Chirps and  y = Degrees

y-intercept = 38.24 and

slope = 0.24
