Answer: ± 1.96
Step-by-step explanation:
Given the following :
Mean (m) time spent = 11.85
Standard deviation = 4 minutes
Since the population of site visits is Normally distributed, Hence, the test statistic will follow a normal distribution :
The test the hypothesis that mean time has changed at 0.05 confidence interval
Normal distributions have a mean value of 0 and standard deviation of 1
Using a two tailed test At 0.05 confidence interval ;
Using the critical value calculator, which in general under normal distributions :
0.05% confidence interval for a two tailed test is
± 1.96
I'm going to assume that is your shape.
If that is your shape, this is simple:
First, you need to solve for the angle TZU. The formula for it is:
mTZU= 0.5(arcTU+arcSR)
mTZu= 0.5(72°+100°) = 86°
Vertical angles, as you should know, are congruent. Always. mTZU is a vertical angle to mSZR. This means mSZR is also 86°
Now, the sum of all angles should be 360°. Now you need to know the remaining angles, you can do this by:
360° - 86° - 86° = 188°
Now, last step. Since mSZR is also equal to RZU because they are vertical angles, this means you need to divide 188° by 2.
188°/2 = 94°
Your answer: m∠SZT = 94°

Answer:
Area of a rectangle = A = 295704 
Step-by-step explanation:
Given Data:
At a certain instant,
height of a rectangle = h = 333 centimeters
width of a rectangle = w = 888 centimeters
To Find Out:
Area of a rectangle = A = ?
Formula:
Area of a rectangle = A = h × w
Solution:
Area of a rectangle = A = h × w
Area of a rectangle = A = 333 × 888
Area of a rectangle = A = 295704

he cut the blue string in half.
he cut the red string in thirds
he cut the green string in sixths.
2(half) goes into 6
3(thirds) go into 6
the sixths stay the same
The answer to this problem would be 17.
