10. from the question; the circle theorem obeyed is "angled formed by semi-circle"
The angle formed in a semicircle is 90 degrees, hence

This gives

But

Substituting values we get

hence, x =12
Answer:
a:four and ninety one hundredths
Step-by-step explanation:
4 this the whole number the word and is used as a indication of the decimal and then 91 would be in hundredths because of the 1

Answer:
y = 2 - 1/2x
Step-by-step explanation:
So we are given the equation 3x + 6y = 12 and are ask to find y.
To find y you must isolate it first.
3x + 6y = 12
(Subtract 3x to isolate the y term)
6y = 12 - 3x
(Divide both sides by 6 to isolate the variable)
y = 2 - 3/6x
(Simplify)
y = 2 - 1/2x
And that is your answer since there is a second variable.
Answer:
The upper limit for the 95% confidence interval for the population proportion of defective gaming systems is 0.022
Step-by-step explanation:
Upper Limit for 95% Confidence Interval can be calculated using p+ME where
- p is the sample proportion of defective gaming systems (
)
- ME is the margin of error from the mean
and margin of error (ME) around the mean can be found using the formula
ME=
where
- z is the statistic of 95% confidence level (1.96)
- p is the sample proportion (

- N is the sample size (1200)
Using the numbers we get:
ME=
≈ 0.007
Then upper limit for the population proportion is 0.015+0.007 =0.022
