Blizzard [7]

Answer:

1.703

Step-by-step explanation:

The reason we try to find t score is because the sample size is below 30, meaning the sample size is small

Hence:

Step 1

We find the degree of freedom

The Degrees of freedom = Number of samples - 1

The random number of samples = 28

= 28 - 1

= 27

Step 2

Using a t score table or t score calculator, we can obtain the t score value for a 90% confidence interval and degree of freedom of 27

90% confidence interval =

10% significance level = 0.10 for two tails or 0.1/2 = 0.05 for one tail

Hence: t90 = 1.703

A certain kite has exactly one acute angle, and it measures 16 degrees. What is the maximum whole-number measure of the angle op
kvv77 [185]

Answer:

In order to do so, we need to use basic algebra. The angles in a kite add up to 360 degrees. so we form the following equation.

x + y + y + 16 = 360

x + y + y = 344 <----(360 -16)

Each letter or variable represents an angle measure. the measures of the three angles left. The 16 degrees is on the bottom of the kite and the angle opposite is the top angle. the two side angles will be the same measure that's why they are both y.

x + 2y = 344

The two side angles will be 90 or greater because there is only 1 acute angle. 90 is the smallest number that can be chosen. so we do the following.

Step-by-step explanation:

x + 2(90) = 344

x + 180 = 344

x = 344-180

x = 164

THE MAXIMUM WHOLE NUMBER MEASURE OF THE ANGLE OPPOSITE OF THE 16 DEGREE ACUTE ANGLE IS 164 DEGREES*
