Answer:
an obtuse angle is greater than 90 and if you think about it 90 plus 90 equals. 180 so if you had two obtuse angles both greater than 90 you would have more than 180 degrees. so the answer for how many angles. of two are in an obtuse triangle is one right here.

Answer:</h2>
The statement that best describes the experimental probability of getting heads is:
It is 10% higher than the theoretical probability.
<h2>
Step-by-step explanation:</h2>
We know that the theoretical probability of getting head is: 0.5
and the theoretical probability of getting tail is: 0.5
Also, the results of experiments are:
Heads Tails
90 60
This means that the experimental probability of getting head is: 90/150=3/5=0.6
and the experimental probability of getting tail is: 60/150=2/5=0.4
Hence, the experimental and theoretical probability of getting head is not same or equal.
Also, the experimental probability of getting head is more than the theoretical probability of getting head and the percent increase is calculated as:
Answer:
234.93 minutes. Divide by 60 and you get 3 hours almost 4.

Answer:
Step-by-step explanation:
by inspection.. ( looking at the graph) we can see that the slope is down hill. so it's going to be negative and also slope = rise / run [rise is negative in this question] soo ... i'm looking carefully to see where the line is crossing the grid marks exactly .. it looks like to me (-3,1) and (2,-3) you tell me if that looks right... if it does .. then the rise / run is 4/5 and this is a negative slope sooo
- 4/5

Answer:
2.275%
Step-by-step explanation:
We start by calculating the z-score
Mathematically;
z-score = (x-mean)SD
here, x = 70.5
mean = 65.5
SD = 2.5
Substituting these values;
z = (70.5-65.5)/2.5
= 5/2.5 = 2
So we want to calculate the probability that;
P( z> 2)
We check the standard normal distribution table for this
That will be
0.02275
In percentage, this is 2.275 %
