To find the amount of matches won:
120 – 50 = 70
So the baseball team has won 70 matches.
To convert this to a percentage:
(Matches won / Total matches ) x 100
(70/120) x 100 = 58.3% (rounded to 1 decimal place)
Answer:
x=21
Step-by-step explanation:
100+3x+x-4=180
100+4x-4=180
96+4x=180
4x=180-96
4x=84
x=21
X/y
x=1 when y= 5
x=2 when y =10
the constant of proportionality = 1/5
Answer:
0.0035289
Step-by-step explanation:
From the question;
mean annual salary = $63,500
n = sample size = 31
Standard deviation = $6,200
Firstly, we calculate the z-score of $60,500
Mathematically;
z-score = x-mean/SD/√n = (60500-63500)/6200/√(31) = -2.6941
So we want to find the probability that P(z < -2.6941)
We can get this from the standard normal table
P( z < -2.6941) = 0.0035289
