Answer:
26 wins , 14 ties
Step-by-step explanation:
Given: Hockey teams receive points when they win and point when they tie. One season, a team won a championship with points. They won more games than they tied.
To Find: How many wins and how many ties did the team have.
Solution:
let the number of wins hockey team have
let the number of ties hockey team have
Now,
Hockey teams receive points when they win and point when they tie.
They won more games than they tied
Solving both equations we get
Hence, the hockey team have wins and ties.
Answer:
The minimum score required for a letter of recognition is 631.24.
Step-by-step explanation:
Problems of normally distributed samples are solved using the z-score formula.
In a set with mean and standard deviation , the zscore of a measure X is given by:
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this problem, we have that:
What is the minimum score required for a letter of recognition
100 - 10 = 90th percentile, which is the value of X when Z has a pvalue of 0.9. So X when Z = 1.28.
The minimum score required for a letter of recognition is 631.24.
Answer: 10.4
Step-by-step explanation:
10x-4/5 = 20
10x-4 = 100
10x = 104
x = 10.4
Simply get the product of 2 and 1/2 by 1/7.
firstly, let's convert the mixed fraction to "improper" and then multiply.
Let the smaller number be x and the larger be (x+19)
x+x+19=35
2x=16
x=8
x+19=27
the numbers are 8 and 27.
