Answer:
Step-by-step explanation:
The equation for the least-squares regression is,
where b is the slope and a is the intercept.
They can be found out by,
where,
r = correlation coefficient = 0.84
= standard deviation of y = 44,910
= standard deviation of x = 28,803
= mean of y = 774,140
= mean of x = 354,718
Putting the values,
Therefore the equation is,
Answer:
m∠WXY + m∠YXZ = 180°
Replacing with the real values:
75° + m∠YXZ = 180°
m∠YXZ = 180° - 75°
<u>m∠YXZ = 105°</u>
Step-by-step explanation:
1. Let's review all the information provided to us to answer the question correctly:
∠WXY and ∠YXZ are supplementary angles
m∠WXY=75°
2. Prove : m∠YXZ=105°
Let's recall that supplementary angles are those angles whose sum is 180 degrees. Therefore,
m∠WXY + m∠YXZ = 180°
Replacing with the real values:
75° + m∠YXZ = 180°
m∠YXZ = 180° - 75°
<u>m∠YXZ = 105°</u>
Answer:
Probability to pick yellow or orange sweet = 3 / 8
Step-by-step explanation:
Given:
Number of yellow sweet = 5
Number of red sweet = 4
Number of green sweet = 8
Number of orange sweet = 4
Number of white sweet = 3
Find:
Probability to pick yellow or orange sweet
Computation:
Total number of sweets = 24 sweets
Probability to pick yellow = 5 / 24
Probability to pick orange = 4 / 24
Probability to pick yellow or orange sweet = 5/24 + 4 / 24
Probability to pick yellow or orange sweet = 9 / 24
Probability to pick yellow or orange sweet = 3 / 8
Answer:
4b - a = 15
Step-by-step explanation:
if you replace the variables with their equivalent counterparts you get the equation 4(7) - 12 = __ when you do the math make sure to do the parentheses first then subtract, just like in elementary school remember pemdas parentheses, exponents, multiplication, division, addition, subtraction. I hope this helps.
good luck:)
Brainliestttt Plssssssss:)
Hey there!
