In this exercise we need to make a division and evaluate the new function at . so we have two functions, namely:
Therefore:
So:
9514 1404 393
Answer:
∠K = ∠M = 55°
Step-by-step explanation:
The two marked angles are opposite the sides marked as congruent. That means the angles are congruent, so we have ...
4x -1 = 2x +27
2x = 28 . . . . . . . . add 1-2x to both sides
x = 14
4x -1 = 4(14) -1 = 55
The measures of the angles are ...
∠K = ∠M = 55°
Answer:
B
Step-by-step explanation:
Answer:
-6
Step-by-step explanation:
We can use the slope formula
m = ( y2-y1)/(x2-x1)
= ( 8-2)/(3-4)
= 6/-1
= -6
Answer:
0.6826
Step-by-step explanation:
The high temperatures for days in January are Normally distributed with a mean of 38 degrees Fahrenheit and a standard deviation of 5 degrees . How many days in January will have temperatures between 33 degrees Fahrenheit and 43 degrees Fahrenheit ? Round your answer to two decimal places.
Solution:
The z score is a score used in statistics to determine by how many standard deviations the raw score is above or below the mean. The z score is given by the formula:
From the normal distribution table, P(33 < x < 43) = P(-1 < z < 1) = P(z < 1) - P(z < -1) = 0.8413 - 0.1587 = 0.6826
