Answer: 2ft 8in
Step-by-step explanation:
Convert to inches - 6ft 8in ----> 6 x 12 + 8 = 80
Divide - 80/2 = 40
Subtract - 40 - 6 = 32
<span>She jogged a total of 6 miles in 55 minutes.So, her average rate was 6 miles/55 minutes. </span>6 miles / 55 min * 60 min/hr = 360/55 = 72/11 miles/hr = about 6.54 mph<span>.

The correct answer is option (b)
Given:
f(x) = 2x + 1
g(x) = 4x^2
h(x) = x^2
Now, g(h(x)) = 4 (x^2)^2 = 4x^4
Now, f(g(h(x))) = 2(4x^4) +1 = 8x^4 + 1
Thus, option b is correct answer
suppose the people have weights that are normally distributed with a mean of 177 lb and a standard deviation of 26 lb.
Find the probability that if a person is randomly selected, his weight will be greater than 174 pounds?
Assume that weights of people are normally distributed with a mean of 177 lb and a standard deviation of 26 lb.
Mean = 177
standard deviation = 26
We find z-score using given mean and standard deviation
z =
=
=-0.11538
Probability (z>-0.11538) = 1 - 0.4562 (use normal distribution table)
= 0.5438
P(weight will be greater than 174 lb) = 0.5438
Answer:
0.08 g
Step-by-step explanation:
20% = 0.2
0.2*0.4=0.08 g
