So u have 9/2 Multiply those 2 numbers and you get 18 no (b+35) B would be whatever number that would go with 18 to make 35 Ex: 18+_=35↪18+17=35 So your answer is 17 (Hope I helped but If I didn't may God be with you for more help)
3.141562.... And it goes on and on and on
–3x + 5.9 ≥ –15.4
subtract 5.9 from each side
-3x >= -21.3
divide by -3 which causes the inequality to flip
x <= 7.1
Answer: -10,-5,0,5
Answer: 0.0228
Step-by-step explanation:
Given : The mean and the standard deviation of finish times (in minutes) for this event are respectively as :-

If the distribution of finish times is approximately bell-shaped and symmetric, then it must be normally distributed.
Let X be the random variable that represents the finish times for this event.
z score : 

Now, the probability of runners who finish in under 19 minutes by using standard normal distribution table :-

Hence, the approximate proportion of runners who finish in under 19 minutes = 0.0228
Answer:
He needs to sell 100 souvenirs
Step-by-step explanation:
We want to know the number of souveniers John has to sell
Let the number of souveniers he sold at the game be s
At a rate of $0.25 per souvenier, the amount earned on souveniers for s souveniers will be:

Now, if we added this to the amount he earns per game, we will have the total $35 earned for working at one game.
Thus, mathematically:
