Answer:
x=40°
Step-by-step explanation:
(x-5)+(x+15)=90°
2x+10=90
2x=80
x=40°
Answer:
The power of horse is: P = 72000 W
Step-by-step explanation:
Given
To determine
P = ?
Using the formula
The ⋅ in the formula represents a scalar product, defined by:
The angle Ф is zero because F and v are are parallel.
Thus the cosine is 1.
Therefore,
P = (1800) (40.0)
P = 72000 W
Hence, the power of horse is: P = 72000 W

Number of bacteria in 1 oz
Multiply both sides by 28
Recall that
This means:
Answer:
d) This is a completely randomized design with two explanatory variables (factors).
Step-by-step explanation:
Explanatory variables are independent variables.
In this case, I prepared two explanatory variables, which are : (i)30-second ad
(ii) 60-second ad,
Then, the explanatory variables were assigned to 4 treatment groups, and each variable is done once or thrice.
All subjects are assigned randomly to all treatment groups, with each treatment group seeing one. We can conclude that this is a completely randomized design with two explanatory variables.
