Answer:
<QRS= (10.x - 1) = (10.6 - 1) = 59°
Step-by-step explanation:
the triangle is not accurate but drawing one is truly useful in calculating. Besides, I don't know how it is called in English but it is something about the exterior angles (maybe)
5y-10=-25
5y=-25+10 addition property of equa
5y=-15 simplifying
Y=-15/5 dividing property
Y=-3

Answer:
3.8 miles
Step-by-step explanation:
Lillian wants her mileage total to be ...
12 +3x = 23.4 . . . . an equation that can be used to find x
4 + x = 7.8 . . . divide by 3
x = 3.8 . . . . . . subtract 4
Lillian would have to ride an average of 3.8 miles each day to reach her goal.

Answer:
The outcomes appear to be equally likely, so a uniform probability model is a good model to represent the probabilities in Tyra's experiment.
Step-by-step explanation:
Probability model, also known as Probability distribution, is a mathematical function that shows the probability of any outcome to occur in an experiment. When those probabilities of occurence are the same for all possible outcomes, it is a uniform probability distribution.
For example, if you roll a fair dice, the probability of having the number 1 is 1/6; for 2 is also 1/6 and etc,
In Tyra's experiment, when the calculates the frequency of each number card, the values are closer together. This means that the probability of taking a card with number 1 written on it is almost the same as taking a card with number 2 and so. In conclusion, Tyra's experiment is au uniform probability model.
