To solve this, first solve the part of the equation in parentheses: (-4+3) = -1. Then multiply using the exponent 2 squared is 2×2 which is 4. Now the equation is -4(-1)+4. Next you multiply, -4(-1)=4. You are then left with 4+4 which equals 8.
-4(-4+3)+2 squared
-4(-1)+2 squared
-4(-1)+4
4+4
8
Answer: 40°
Step-by-step explanation:
You add 90° for the right angle and 50° for the other and subtract from 180°
Step 1
Given; If Body temperatures of healthy adults have a bell-shaped distribution with a mean of 98.20°F and a standard deviation of 0.93°F.
Using the empirical rule, what is the approximate percentage of healthy adults with body temperatures between 96.34°F and 100.06°F?
Step 2
![P(96.34The empirical rule states that 95% of the data fall within two standard deviations of the mean. Thus, 95% of healthy individuals have body temperatures between 96.34F and 100.06F.Answer;[tex]95\text{\%}](https://tex.z-dn.net/?f=P%2896.34The%20empirical%20rule%20states%20that%2095%25%20of%20the%20data%20fall%20within%20two%20standard%20deviations%20of%20the%20mean.%20Thus%2C%2095%25%20of%20healthy%20individuals%20have%20body%20temperatures%20between%2096.34F%20and%20100.06F.%3Cp%3E%3C%2Fp%3E%3Cp%3E%3Cstrong%3EAnswer%3B%3C%2Fstrong%3E%3C%2Fp%3E%5Btex%5D95%5Ctext%7B%5C%25%7D)
4 divide 4/9
4 times 9/4
= 9
I’m pretty sure the answer is 30!
