Wittaler [7]2 years ago
4 0

Answer: 9

Step-by-step explanation:

Formula : Mean = \dfrac{\text{Sum of observations}}{\text{Number of observaions}}

Given: 5 students participated in a push-up competition.

The amount of push-ups each student completed is listed: 12, 7, 10, 11,5.

Mean = \dfrac{12+7+10+77+5}{5}

=\dfrac{45}{5}=9

Hence, the mean number of push-ups = 9

How would I determine whether AB is tangent to oc?<br> The o is a circle dot
icang [17]

Answer:

see explanation

Step-by-step explanation:

If AB is a tangent then ∠ ABC = 90° and Δ ABC is right

Using the converse of Pythagoras' identity

If the square of the longest side is equal to the sum of the squares on the other 2 sides.

15 is the longest side and 15² = 225

9² + 12² = 81 + 144 = 225

Thus Δ ABC is a right triangle at B

Thus AB is a tangent to the circle at B

Standard normal curve between z=.42 and z=1.92<br> a= .6902<br> b= .3098<br> c= .1902<br> d= .8098
soldier1979 [14.2K]
The correct answer is Choice B: 0.3098.

To find the answer, you have to use a normal distribution table. Look up the percents for each z-score and subtract them to find the region between.

z = 1.92 the percent is 0.9726

z = 0.42 the percent is 0.6628

0.9726 - 0.6628 = 0.3098
