Step-by-step explanation:
what do you mean "what's the answer for this ?"
you only need to put 3 in place of x (that's what is meant by "x is 3" or x = 3) and then simply calculate.
you know what "squaring" ("something to the power of 2" or x²) means ? it means that you have to multiply that "something" by itself.
y = 3² + 11 = 3×3 + 11 = 9 + 11 = 20
that's all there is to this.
Answer:
The percentage of men meeting the height requierements is 11.47%.
As women have a less mean height, closer to the height requierments than men's mean height, it is expected that more percentage of women will fall within the height requirements.
Step-by-step explanation:
We have men's height normally distributed with mean 67.4 in and standard deviation 3.7 in.
The amusement park requires heights between 57 in and 63 in.
We can calculate the proportion using the z-scores and the standard normal probability distribution.
The percentage of men meeting the height requierements is 11.47%.
The answer is 9, here are all the possible combinations...
road, road
road, bridge
road, ferry
bridge, bridge
bridge, ferry
bridge, road
ferry, ferry
ferry, bridge
ferry, boat
(or you can do 3 input combinations by 3 output combinations "3 x 3" = 9)
Cheers!
(make them equal to each other)
10x-1 = 14x-37
(combine like terms)
-4x = -36
(divide by -4)
x=9
Hope this helps! Have a good day/night!
Answer:
x=1
Step-by-step explanation:
7x+35=4x+32+6
7x-4x=32+6-35
3x=3
x=3/3
