Answer:
Graph C with values below
Step-by-step explanation:
To do this you substitute x with the values of x given to solve for y:
-3:
- y= (-3)³-2(-3)+1
- y= (×-27)+6+1
- y= -13.5+7
- y= -6.5
-2:
- y= (-2)³-2(-2)+1
- y= (×-8)+4+1
- y= -4+5
- y= 1
0:
- y= (0)³-2(0)+1
- y = 0+0+1
- y= 1
2:
- y= (2)³-2(2)+1
- y= (×8)-4+1
- y= 4-4+1
- y=1
Using these values we can fill out the table and see the It must be graph C that is the correct curve.
or, 2+10=5x-2x
or, 12=3x
or, 12÷3=x
or, 4=x
therefore, x=4
Step-by-step explanation:
first, you need to arrange the term in proper way. while doing that you need to change the signs and then you need to add or subtract them and to find the value of x you need to divide 12 by 3 and the answer will come out.
Answer:
Mean of 0 and a standard deviation of 1.
Step-by-step explanation:
To transform the entire population into z-scores, one would need to normalize/standardize the scores.
The standardized score for any value is the value minus the mean then divided by the standard deviation.
Given mathematically as
z = (x - μ)/σ
The normal distribution shows how much a set of data points spread out around the mean.
A z-score is basically expressing how many standard deviations away from the mean is a particular data point.
z-score for the mean = (μ - μ)/σ = (60 - 60)/8 = 0
And any variable that is one standard deviation away from the mean will have a z-score of 1.
For example, 68 is one standard deviation away from the mean.
z-score for 68
z = (x - μ)/σ = (68 - 60)/8 = 1.
It is evident that normal distribution, when converted to z-scores has a mean of 0 and a standard deviation of 1.
Answer:
463u
Step-by-step explanation:
to find surface area you multiply things like a*b a*c b*c, but you only need two in this case,you dont need 4.3*14, so it just 4.3*5 and 5*14, multiply those and add em
