Answer: the statement “measure of <4 is 105 degrees” is incorrect.

Explanation: This is because since both angles 1 and 3 are vertical, this means they are both 95. This gives us 190 (95x2). Now we subtract this from 360 which gives us 170. Since angles 2 and 4 are vertical, we divide by 2, which gives us 85, not 105.

Hope this helps! :)

The range of the function f(k) = k2 + 2k + 1 is {25, 64}. What is the function’s domain?
lorasvet [3.4K]
<span>The domain of the function can be obtained by pluging the values of the range into f(x), i.e domain = {k^2 + 2k + 1 = 25, k^2 + 2k + 1 = 64} = {k^2 + 2k - 24 = 0, k^2 + 2k - 63 = 0}. Solving the two quadratic equations, we have that the range is {-9, -6, 4, 7}.I hope that my answer is helpful! Let me know if you need something more :)</span>

the average number of chocolate chips in a particular brand of chocolate chip chewy cookie is 19. the standard deviation is 2.6.
zzz [600]

The probability illustrated shows that the

percent of cookies would have between 13.8 and 24.2 chips is 95.44%.

<h3>How to calculate the probability?</h3>

It is important to note that the requirement to solve the probability between z-values is to know that the probability between the z-values is the difference between the probability of the greatest z-value and the lowest z-value.

This will be illustrated thus:

Z value for 13.8, z =(13.8-19)/2.6 =-2

Z value for 24.2, z =(24.2-19)/2.6 = 2

P( 13.8<x<24.2) =P(-2<z<2)

=P( z <2 –P(z < -2)

=0.9772 -0.0228

=0.9544

= 95.44%

The percent is 95.44%.
