(x-5)(x-5)
x*x-5*x-5*x-5*-5
x^2-5x-5x+25
x^2-10x+25
Answer:
D
Step-by-step explanation:
First multiply by t
at = vf -vi
Then subtract vf
at - vf = -vi
Then multiply by -1
Vi = vf - at
Answer:
1.041
Step-by-step explanation:
In order to increase by 4.1%, you must multiply whatever number you have by the decimal: 1.041.
Say the number we want to increase by 4.1% is x. Then:
x + (4.1%) * x = x(1 + 4.1%) = x(1 + 0.041) = 1.041x
So, you would multiply by 1.041.
Hope this helps!
Answer:
50
Step-by-step explanation:
because the total number of traingle =180 so we have 15 and 35 which equal 50 and the inside angle = 130 and x = 50
The histogram is especially useful in comparing mean and median values of a variable. We have that 5.5+6+7+10+7.5+8+9.5+9+8.5+8+7+7.5+6+6.5+5.5=111.5 Since there are 15 values, their mean is 111.5/15=7.43 which is very close to the mean. We also have that 7 onservations are lower than 7.4 while 8 are bigger than 7.4; hence, the diagram is rather balanced and not left-skewed. We cannot tell immediately which one is larger since the values are too close. Any such random process can usually be approximated to a greater or smaller degree by a normal curve; the more points, the better. The histogram shows this (it is kind of a discrete normal curve); all points except 4 will be in this interval of bars.
