Answer:
1) 10
Basic facts:
<em>we can tell a right angle if there is a small square drawn where the angle measuring should be done</em>
Step-by-step explanation:
<u>Main step</u>
<u>90-60=30</u>
<u>30=3x</u>
<u>divide by 3</u>
<u>10 =x</u>
the value of x is 10
so option 1

The linear regression equation obtained by fitting the data using a regression model is :
ŷ = -0.017X + 6.03
From the regression plot, the relationship between the two variables, speed and lifetime is negative, that is an increase in one variable will lead to a corresponding decrease in the other.
Distribute -3 to the rest of the numbers by multiplying them together. That’s all you need to do you don’t have to solve
Answer:
2/3
Step-by-step explanation:
0/0 is 0
1/2 is 1 of 2
2/3 is 2 of 3
3/4 is 3 of 4
hopefully it helps!
