As a fraction, it is 6/25. As percentages are out of 100, you need to divide 100 by 25, and this will give you the answer as to what you need to multiply the fraction by. 100/25=4. Therefore, you need to multiply the fraction by 4 to get a percentage. 6x4= 24, 25x4=100. 24/100 is equal to 24%
Therefore, 6/25 as a percentage is 24%
Hope this helps :)
T(x,y) is given by
<span>x = (1/2) (6 – 2) + 2 and y = (1/2) (4 – 6) + 6
so
</span><span>
x = (1/2) (4) + 2 and y = (1/2) (-2) + 6
</span><span>x = 2 + 2 and y = -1 + 6
x = 4 and y =5
so T(4,5)
ans is C</span>
Answer:
90% confidence interval for the true mean weight of orders is between a lower limit of 103.8645 grams and an upper limit of 116.1355 grams.
Step-by-step explanation:
Confidence interval for true mean weight is given as sample mean +/- margin of error (E)
sample mean = 110 g
sample sd = 14 g
n = 16
degree of freedom = n - 1 = 16 - 1 = 15
confidence level = 90% = 0.9
significance level = 1 - C = 1 - 0.9 = 0.1 = 10%
critical value (t) corresponding to 15 degrees of freedom and 10% significance level is 1.753
E = t × sample sd/√n = 1.753×14/√16 = 6.1355 g
Lower limit of sample mean = sample mean - E = 110 - 6.1355 = 103.8645 g
Upper limit of sample mean = sample mean + E = 110 + 6.1355 = 116.1355 g
90% confidence interval is (103.8645, 116.1355)
