1980mg(g/1000mg)=1.98g

2g-1.98g=0.02g or 20mg is the difference between the two weights.

PLEASE HELP PLEASE SOLVE ALL!!!

VARVARA [1.3K]

Answer:

x= -6 | I only have an answer for #7 but you should use a website called Symbolab :)

Step-by-step explanation:

x+16+x+12+2x+15=19

group like terms:

4x+43=19

subtract 43 from both sides:

4x+43=19

-43 -43

simplify:

4x=-24

divided both sides by 4:

x=-6

A simple random sample of 15 pistons is selected from a large population whose diameters are known to be normally distributed. T

pav-90 [236]

Answer:

95% confidence interval for the population variance is (2.89, 5.11)

Step-by-step explanation:

Confidence Interval (CI) = variance + or - (t×s)/√n

Standard deviation (s) = 2, variance (s^2) = 2^2 = 4, n = 15, degree of freedom = n - 1 = 15 - 1 = 14

t-value corresponding to 14 degrees of freedom and 95% confidence interval is 2.145

Lower bound = variance - (t×s)/√n = 4 - (2.145×2)/√15 = 4 - 1.11 = 2.89

Upper bound = variance + (t×s)/√n = 4 + (2.145×2)/√15 = 4 + 1.11 = 5.11

95% confidence interval is (2.89, 5.11)
