Answer:
∠DAB = 80°
∠BAC = 105°
Step-by-step explanation:
You are given ...
∠DAC = 25° = (x -20)°
Adding 20°, we have ...
x° = 45°
Then the measures of the other angles are ...
∠DAB = (2x -10)° = 2(45°) -10°
∠DAB = 80°
and
∠BAC = ∠DAB +∠DAC = 80° +25°
∠BAC = 105°

Decimal = -0.77777...….
Step-by-step explanation:
Answer:
1) 1/3
2) 4:1
Step-by-step explanation:
Answer:
Here both probabilities are not equal.
Therefore the die is not fair and biased.
Step-by-step explanation:
Now n= 1200 times and x = 419 times.
a) Empirical Probability:

Probability = 0.349
b) Theoretical Probability:

Here both probabilities are not equal.
Therefore the die is not fair and biased.
For this case we have to take into account the following conversions:

Let's first transform the expression to miles per seconds squared:

Then, we transform the result to miles per minute squared.
We have then:
Answer:
the rate in miles/min^2 is:
