what is the standard deviation and variance of 10, 10, 10, 10, 13, 20, 23, 32, 32, 32, 32, 47, 50, 53, 60, 60, 63, 72, 72, 72, 7

Answer:
bro/sis through this solution u can solve ur values
Step-by-step explanation:
To calculate the variance, you first subtract the mean from each number and then square the results to find the squared differences. You then find the average of those squared differences. The result is the variance. The standard deviation is a measure of how spread out the numbers in a distribution are.
I hope this will help you

Answer:
the vertex angle = 80°
Step-by-step explanation:
V: vertex angle B: base angle
V / B = 8 / 5
5V = 8B
V + 2B = 180
4V + 8B = 720
4V + 5V = 720
9V = 720
V = 80°
check: B = (180 - 80) / 2 = 50°
V / B = 80 / 50 = 8 /5 (8 : 5)
Answer:
1). Because whole number doesn’t allow decimal numbers.
2). Because whole number doesn’t allow negative numbers. It starts with 0, 1, 2, 3....
If you evaluate your polynomial at x= - 3, the polynomial = 0. So, that means ( x + 3 ) is a factor. Either using long division, or synthetic division, you'll find out that 2x^3 - 9x^2 + 3x + 4 remains. Then if you try x = 4 on that remaining polynomial, it will = 0. Use long division or synthetic division to find out that 2x^2 - x - 1 is left over. That trinomial factors into ( 2x + 1 ) ( x - 1 ).
factored form is ( x+3 )( x - 4 )( 2x + 1 )( x - 1 )
