Answer:

The probability that a randomly selected student prefers dogs or is female is 1.08

Step-by-step explanation:

Number of females = 52

Number of dogs = 56

Total no. of preferences = 100

Probability of selecting a dog =\frac{56}{100}

Probability of selecting a female =\frac{52}{100}

The probability that a randomly selected student prefers dogs or is female = \frac{56}{100}+\frac{52}{100}=1.08

Hence the probability that a randomly selected student prefers dogs or is female is 1.08

stellarik [79]

Answer:

150/250

Step-by-step explanation:

24/42, 75/135, 150/250, and 75/150 I believe is what you're asking. We know 75/135 is better than 75/150 so 75/150 is out of the equation. If we multiple 75/135 by 2 we get 150/270 which is more than 150/250, so 75/135 is out of the equation. Now to compare 24/42 and 150/250 we can divide their fractions, if we divide 24/42 we get 0.57, so 57%. If we did 150/250 we get 0.6 or 60%. So 150/250 is the best score.

Carla pays $20 per month for her phone service, plus $0.08 for each long
Kisachek [45]

Answer:

Slope = 0.08 dollars per minutes.

Step-by-step explanation:

Carla pays $20 per month for her phone service, plus $0.08 for each long-distance minute used.

Therefore, if Carla talks for m minutes in the long-distance call, then the situation can be modeled by the equation  

C = 20 + 0.08m ............ (1), where C is the total cost for her phone service per month.

Here, 20 is the fixed price and 0.08m is the variable price for her phone charges.

This equation (1) represents a straight line with y-intercept as 20 and the slope as 0.08, where m plotted along x-axis and C is plotted along the y-axis. (Answer)
