Answer:
181.46 cm
Step-by-step explanation:
28.47 * 637.47 / 100 = 181.46
The correct answer is 7,500.
Answer:
135,296 ÷ 16 = 8,456
Step-by-step explanation:
i think this is the answer
In the right triangle PQR:
Hypotenuse: QR = QN + NR = 12 + 6 = 18 cm
PN² = QN · NR
PN² = 12 · 6 = 72
PN = √72 = √(36 · 2 ) = 6√2 cm
PQ² = (6√2)² + 12² = 72 + 144 = 216
PQ = √216 = √(36 · 6 ) = 6√6 cm
PR² = 18² - (6√6)² = 324 - 216 = 108
PR = √108 = √(36 · 3) = 6√3 cm
Answer:
PN = 6√2 cm,
PQ = 6√6 cm,
PR = 6√3 cm.
Answer:
t = [ (x1' - x2' ) - d ] / SE . p < 0.05 suggests means are equal, p > 0.05 suggests means are unequal.
Step-by-step explanation:
Null Hypothesis [H0] : There is no difference between average estimates of two garages, M1 = M2
Alternate Hypothesis [H1] : There is difference between average estimates of two garages, M1 ≠ M2
Hypothesis can be tested by t test
t = [ (x1' - x2' ) - d ] / SE , where :-
x1' & x2' are sample means, SE = sqrt[ (s1^2/n1) + (s2^2 /n2) ] , d is the hypothesized difference between population means, and SE is the standard error ie 0 here
If the p value corresponding to calculated t value is < p value as per significance level (0.05) : We reject null hypothesis & state that M1 ≠ M2
If the p value corresponding to calculated t value > p value as per significance level (0.05) : We accept null hypothesis & state that M1 = M2
