A is correct
All the other ones are false and if you plug in 3 in the equation, 3(3+9) = 15
Step-by-step explanation:
sin^(2)x + sin x = 0
sin x(sin x +1)= 0
sin x = 0 or sin x = -1
so, x = 0°, 180°, 270°
{0°, 180°, 270°}
Answer:
x = 2 (For First question)
Step-by-step explanation:
8^ 1/6 * 2^x = 32^1/2
8^1/6 * 2^x 8^1/6 = 32^1/2/8^1/6
2^x = 32^1/2 / 8^1/6
2^x = 4
2^x = 2^2
x =2
Question 2:
Answer: 50
Step-by-step explanation:
8^1/3/5^-2
= 2/5^-2
= 2/1/5^2
= 2* 5^2/1
= 2 * 5^2
= 2 * 25
= 50
Answer:
Option A.
Step-by-step explanation:
We need to find the residual for a student with an observed BMI of 25 and an observed hrs/month under the influence of 18.8.
Actual value = 25
Predicted value = 18.8
Residual = Actual value - Predicted value
Residual = 25 - 18.8
Residual = 6.2
Round the answer to two decimal places.
Residual = 6.20
The residual value is 6.20.
Therefore, the correct option is A.
