Answer:
Therefore,
Step-by-step explanation:
Consider a Δ ABC with
m∠ B= 45°
m∠ C = 90°
AB = c = 15 cm
To Find:
BC = a = y ?
Solution:
Triangle sum property:
In a Triangle sum of the measures of all the angles of a triangle is 180°.
We know in a Triangle Sine Rule Says that,
In Δ ABC,
substituting the given values we get
∴ 
Similarly for 'x',
Therefore,
Answer: Choice A
The simulated probability probability is 0.450, which is less than the theoretical probability
=========================================
Explanation:
In the given list of numbers shown, count how many times an even number comes up. In this case, the even numbers that show up are, in this order: 2, 6, 6, 4, 4, 6, 2, 2, 6
There are 9 even numbers in the list of 20 total. So the simulated probability of getting an even number is 9/20 = 0.450 which is a 45% chance. This is based on this current data set.
If we assumed that each side of the die was equally likely to be landed on, then there are three even numbers (2,4,6) out of six total (1 through 6). So the theoretical probability of getting an even number is 3/6 = 1/2 = 0.500
Comparing 0.450 to 0.500, we see that 0.450 is smaller. You can think of it as like saying "450 is smaller than 500".
Answer:
n=0
Step-by-step explanation:
14+3(0)=14
:) :) :)
The sum of the angles of a triangle is 180 degrees.
a + b + c = 180.
a + (a+10) + 2a = 180
3a + 10 = 180
3a + 10 - 10 = 180 - 10
3a = 170
a = 42.5 degrees
b= 52.5 degrees and c = 85 degrees.
Answer:
b.) 104
Step-by-step explanation:
Percent formula:
x/y = p/100
where x is the fraction, y is the total, and p is the percent
This means:
x = number of games the team won
y = total number of games
p = percent the number of teams won
Let's plug these values into the equation:
x/y = p/100
x/160 = 65/100
Solve by cross-multiplying:
x/160 = 65/100
100(x) = 100x
160(65) = 10,400
100x = 10,400
/100 /100
x = 104
Therefore, the team won 104 games.
