Answer:
x=5, y=4. (5, 4).
Step-by-step explanation:
2x-3y=-2
4x+y=24
------------------
-2(2x-3y)=-2(-2)
4x+y=24
----------------------
-4x+6y=4
4x+y=24
--------------
7y=28
y=28/7
y=4
4x+4=24
4x=24-4
4x=20
x=20/4
x=5
Solution :
The normal body temperature of any human body is considered to be 98.6
. But there is a constant debate about the body temperature of a long held standard to the body temperature.
It is given that :
Null hypothesis and alternate hypothesis :
And 
n is given as = 180
Test statistics = 3.64
Prove = 0.018 < α = 0.05 (let reject null hypothesis for α = 0.05 )
Therefore, their results are statistically significant and the result is unlikely due to chance alone.
Answer: 6.2
Step-by-step explanation: 3.1 = x/2
x/2=3.1
x/2(2)=3.1(2)
x=6.2
First you must change 3/8 into a decimal, so the number would be 45.375. To find scientific notation you have to move the decimal between a factor of 1-10. 4.5375 . You moved over the decimal once toward the left. so scientific notation would be 4.5375 X 10^1
