Answer:
Step-by-step explanation:
From the information given:
For Adult Men
Mean 
= 69.5
Standard deviation 
= 2.4
observed value X = 74
For Adult Women
Mean = 63.8
Standard deviation = 2.6
observed value X = 70
Therefore ; the values for their z scores can be obtained in order to determine who is more unusually tall within his or her respective sex
For Adult Men :
z = 1.875
For Adult Women :
z = 2.3846
Thus; we can conclude that , the women is more unusually tall within his or her respective sex
Answer:
The equation for this is: 
Step-by-step explanation:
We have that the number though is n.
Adds 10:
This means that now we have: 
Multiplies by 3:
This means that now we have: 
Gets 42:
This means that:
Answer:
speed is given by:
speed=distance/time
given that:
1 mile=1,760 yards
1 hour=60 min
then the speed in yards/sec will be:
distance Ashley covered is 15 miles
time=2 hours
thus;
speed=(15x1760)/(2x60)
=220 yards/ min
Step-by-step explanation:
Hi hope helps you :)
4x² - 9x² + 5 = 0
4x² - 4x - 5x + 5 = 0
4x(x - 1) - 5(x - 1) = 0
(4x - 5)(x - 1) = 0
Set each binomial equal to zero.
4x - 5 = 0
4x = 0 + 5
4x = 5
x = 5/4
x - 1 = 0
x = 0 + 1
x = 1
Your solutions are x = 1, 5/4
