Answer:
x = 7.3
Step-by-step explanation:
When solving for missing sides using angles, use trig functions.
We have the angle 63° to use.
We are given the hypotenuse of the triangle, as well as the side adjacent to the angle, so we can use the cos function.
Cos T = (adjacent side)/(hypotenuse)
Here we know 'T' and the hypotenuse, so plug them in and solve
Cos 63° = x/16
(16)Cos 63° = x (multiply both sides by 16 to isolate 'x')
7.263847996 = x (use your calculator to solve the left side)
7.3 = x (rounded to the nearest 10th)
Recall that for |<em>x</em>| < 1, we have
Differentiating both sides gives
and multiplying both sides by 8 gives the series for <em>f(x)</em> :
and this converges over the same interval, |<em>x</em>| < 1, so that the radius of convergence is 1.
Answer:
(0.0706, 0.1294)
Step-by-step explanation:
Confidence interval of a proportion is:
CI = p ± CV × SE
where p is the proportion,
CV is the critical value (z score or t score),
and SE is the standard error.
The sample is large enough to estimate as normal. For 95% confidence level, CV = z = 1.96.
Standard error for a proportion is:
SE = √(pq/n)
SE = √(0.1 × 0.9 / 400)
SE = 0.015
The confidence interval is:
CI = 0.1 ± (1.96)(0.015)
CI = (0.0706, 0.1294)
Round as needed.
