Answer:
j=7
Step-by-step explanation:
11j-20=6j+15
-6j -6j
5j-20=15 Isolate the variable:
+20 +20
5j=35 Divide to get variable by itself
j=7
Hope this helps :)
Answer:
A
Step-by-step explanation:
find the area of the inner triangle and then multiply it by 4
If the length is two times its width and its perimeter is 36cm. we can write the following equation
let the width be X.
so the equation will be:
(X + 2X)2=36cm or
2X + 4X=36cm
Distance biked before lunch = 1
km (the number is written in mixed fraction)
⇒ Distance biked before lunch = ![\frac{13}{8}](https://tex.z-dn.net/?f=%5Cfrac%7B13%7D%7B8%7D)
Distance biked after lunch = 6
km (the number is written in mixed fraction)
⇒ Distance biked after lunch = ![\frac{25}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B25%7D%7B4%7D)
We need to determine how much farther does Hallie bike after lunch than before lunch
Extra distance biked after lunch vs. before lunch =
- ![\frac{13}{8}](https://tex.z-dn.net/?f=%5Cfrac%7B13%7D%7B8%7D)
⇒ Extra distance biked after lunch vs. before lunch = ![\frac{50-13}{8}](https://tex.z-dn.net/?f=%5Cfrac%7B50-13%7D%7B8%7D)
⇒ Extra distance biked after lunch vs. before lunch = ![\frac{37}{8}](https://tex.z-dn.net/?f=%5Cfrac%7B37%7D%7B8%7D)
⇒ Extra distance biked after lunch vs. before lunch = 4
(in mixed fraction)
Hence, Hallie biked 4
km extra after lunch vs. before lunch.
Answer:
- Is not met ( A )
- Is not met ( A )
- Does not need to be checked for multiple linear regression ( B )
- Does not need to be checked for multiple linear regression ( B )
Step-by-step explanation:
Linearity condition is : <em>NOT MET </em>
The equal variance condition is : <em>NOT MET</em>
The 10% condition :<em> Does not need to be checked for multiple linear regression </em>
The success failure condition : <em>Does not need to be checked for multiple linear regression</em>
