Answer:
5/9
Step-by-step explanation:
Find the GCD (or HCF) of numerator and denominator. GCD of 10 and 18 is 2.
10 ÷ 218 ÷ 2.
Reduced fraction: 59. Therefore, 10/18 simplified to lowest terms is 5/9.
W=2j, m=5w, (m+4)=6(j+4)
using w from first in second you get:
m=5(2j)=10j, m+4=6j+24
m=10j, m=6j+20, since m=m we can say
10j=6j+20
4j=20
j=5, and since m=10j
m=50
So the man is 50 years old
Answer:
A. -1.6; not significant
Step-by-step explanation:
The z-score of a data set that is normally distributed with a mean of 
and a standard deviation of 
, is given by:
.
From the question, the test score is: 
, the mean is 
, and the standard deviation is 
.
We just have to plug these values into the above formula to obtain:
.
This simplifies to: 
.
.
We can see that the z-score falls within two standard deviations of the mean.
Since 
the value is not significant.
The correct answer is A. -1.6; not significant
