1
because
1^2=1
1^2×15=15
1×15=15
So 1^2*15=1×15
Equation looks like this
15x^2=15x
subtract 15x
15x^2+15x=0
factor
15x(x-1)=0
solutions are 0 or 1 but seeing it said non zero number it must be 1
Answer:
The weather studies fall under atmospheric science.The Christopher and Emma should learn about the local weather and then identify affects on the locality.
Step-by-step explanation:
The weather studies are dynamic. Sometimes weather follows trend but in some cases weather does not follows trend and there is heavy rainfall or snowfall than expected. The forecast of weather is very difficult to be accurate. However near guess can be made about the weather conditions by observing the trends of previous years.
Answer:
Diana's score is better.
Step-by-step explanation:
In Diana case :
Score = 92
Mean score , μ = 71
Standard deviation σ = 15
So,
P( x ≥ 92 ) = 1 - P( x ≤ 92 )
= 1 - P(z ≤ )
= 1 - P( z ≤ )
= 1 - P( z ≤ 1.4 )
= 1 - 0.9192
= 0.0808 = 8.08 %
⇒P( x ≥ 92 ) = 8.08%
∴ we get
Diana score is > 91.92% other students in the class.
In Micheal case :
Score = 688
Mean score , μ = 493
Standard deviation σ = 150
So,
P( x ≥ 688 ) = 1 - P( x ≤ 688 )
= 1 - P(z ≤ )
= 1 - P( z ≤ )
= 1 - P( z ≤ 1.3 )
= 1 - 0.9032
= 0.0968 = 9.68 %
⇒P( x ≥ 688 ) = 9.68%
∴ we get
Micheal score is > 90.32% other students in the class.
From both scores , we can conclude that
Diana's score is better.
Each side of a box is s = 2.5 units
volume of one box is length * breadth * height
since its a cube all sides are equal
volume of one box = s³ = 2.5³
since there are 4 boxes,
total volume V = 4s³
V = 4 * 2.5³ = 4 * 15.625
= 62.50 cubic units
third response is correct
