Answer:
10
Step-by-step explanation:
if if 70% of it is = 7
then multiply 100 by 7 then divide it by 70
100×7 = 70x
x = 10
Answer:
(6,8)
Step-by-step explanation:
You can just substitute the options into the inequalities
e.g. For option 1, you can put x=6, and you will find the RHS is smaller than LHS in both inequalities.
Answer:
54.07 inches
Step-by-step explanation:
Given the regression equation :
y = 18.5 + 0.890x
y = pulse rate in beats per minute
x = height
The best predicted pulse rate of a woman who is 65 inches
Put y = 65 in the regression equation :
65 = 18.5 + 0.890x
65 - 18.5 = 0.890x
46.5 = 0.890x
Divide both sides by 0.890
46.5 / 0.890 = 0.890x / 0.890
54.0697 = x
The best predicted pulse rate for a woman wo is 65 inches tall is 54.07 inches
The answer to your question is 8,000.00
More than the twice of the mean is 28.8 and I don't understand the meaning of typical. Seeing this porblem statement said that 3 brands had been contaminated more than twice the average, We would assume it's typical, then again it depends on what you define typical as. I think the mean is like "find the probability that a tested bar has at least twice as many insect fragments as the mean, and see if that number is really really small".
The probability is 0.000463 and this is really small, but I really don't understand what is the meaning of typical in this problem.
