Answer:
∠ABC= 40° ∠CBD=60° ∠EBD=80°
Step-by-step explanation:
Step 1: 2x+3x+4x=180
A straight line is 180 degree's, and to get the value of the different angles, you have to add the three angle measures.
Step 2: 9x=180
Combine like terms
Step 3: x=20
Divide/ Isolate the variable
Step 4: 2(20)=40 3(20)=60 4(20)=80
Plug the answer back in
Answer:
12.1 meters. Hope this helped, would love brainliest!
Step-by-step explanation:
For this question we will have to try each option.
12.675+2.3=14.975 14.975+14.975+12.675+12.675=55.3 This ones not it.
25.35+2.3=28.65 28.65+28.65+25.35+25.35=108 This ones not it either.
12.1+2.3=14.4 14.4+14.4+12.1+12.1=53 THIS ONES IT!
we do not have to do the last one
The mean of the dataset is the average, while the median is the middle element.
- <em>The mean and the median of the given dataset is 98.2</em>
- <em>The results support the common belief that the mean body temperature is 98.6F</em>
<em />
The mean of the dataset is calculated using:
So, we have:
The median position is:
This means that the median is the average of the 24th and 25th element
Using the sorted dataset, we have:
<em>Because the calculated mean and the common belief (98.6) are close, then we can conclude that the results support the common belief that the mean body temperature is 98.6F</em>
<em />

<span>You can solve this problem using this equation: 34x + 14 = 30x + 22.
The x stands for how many points each multiple choice question is worth. 34x is the number of multiple choice questions Francine got correct multiplied by the currently unknown number each point is worth, while 14 represents the 14 points that Francine was given for her essay. 30x is the number of multiple choice questions Cheryl got correct multiplied by the currently unknown number each point is worth, while 22 represents the 22 points that Cheryl was given for her essay.
To solve, we can subtract 30x from 34x on the left side of the equation, and subtract 14 from 22 on the right side of the equation. That leaves, 4x = 8. Next step would be dividing 4 from each side which gives us x = 2. In order for Francine and Cheryl to receive the same test score, each multiple choice questions would have to be worth 2 points.</span>
