Answer:
A, 10 degrees
Step-by-step explanation:
A 10 degrees because 4×10+5=45
Answer:
1. 40%
2. The theoretical probability is 3% greater than the experimental probability.
Step-by-step explanation:
We are informed that a number cube is rolled 20 times and the number 4 is rolled 8 times. The experimental probability of rolling a 4 is;
(the number of times a 4 was rolled)/(total number of rolls)
8/20 = 0.4
0.4*100 = 40%
The experimental probability of obtaining at least one tails, one or more tails, is represented in mathematical notation as;
P(HT or TH or TT)
The above events are mutually exclusive, thus;
P(HT or TH or TT) = P(HT) + P(TH) + P( TT)
= (22+34+16)/(28+22+34+16)
= 0.72 = 72%
On the other hand, the theoretical probability of obtaining at least one tails,
P(HT or TH or TT) = 3/4
= 75%
This is because there is at least one tail in 3 out of 4 possible outcomes.
Therefore, it is true to say that the theoretical probability is 3% greater than the experimental probability.
Answer:
30°
Step-by-step explanation:
A dilatation does not change the size of the angles in the triangles only the length of the sides.
ΔABC and ΔXYZ are therefore similar and corresponding angles are congruent, hence
∠X = ∠A = 50°
∠Y = ∠B = 100°
The sum of the 3 angles in the triangle = 180°, thus
∠Z = 180° - (50 + 100)° = 180° - 150° = 30°

The equation that can be used to determine the time for each leg is D. 600t = 480(18 – t)
<h3>How to calculate the equation?</h3>
Speed on going ,= 600 miles per hour.
Speed on return = 480 miles per hour
Time on returning = 18 - t
Distance = Speed × Time
Distance = 480(18 - t)
The equation that can be used to determine the time for each leg will be:
600t = 480(18 – t)
