Assuming that you have the lengths of both legs of the right triangle, use the formula
A = bh/2, where b is thought of as the base and h is thought of as the height.
Answer:
x=47
59+59=118
x+24+x=118
2x+24=118
94=2x
x=47
Step-by-step explanation:
Please give me brainliest if right
To find the slope given two points, just solve the equation (y1-y2)/(x1-x2)=m. So (2-r)/(r-5)=0. To get the slope to be 0, you need only the numerator to be 0 (if the denominator is 0, the slope is undefined).
So 2-r=0, and r=2.
<h3>Answer: 2.25</h3>
==================================
Explanation:
Multiply the values in the second and third columns. Do this row by row.
Row1: 3*20 = 60
Row2: 2*12 = 24
Row3: 1*6 = 6
Row4: 0*2 = 0
Add up the products to get 60+24+6+0 = 90
Then divide this by the total frequency 20+12+6+2 = 40 to get 90/40 = 2.25
Answer:
The answer is "0.0547".
Step-by-step explanation:
![P(Correct) = 0.50\\\\n = 10\\\\x = 8](https://tex.z-dn.net/?f=P%28Correct%29%20%3D%200.50%5C%5C%5C%5Cn%20%3D%2010%5C%5C%5C%5Cx%20%3D%208)
Using the binomial distribution:
![\to P(x,n) = n_{C}_x \times p^x \times (1-p)^{(n-1)}\\\\\to P(x \geq 8) = 1 - P( \leq 7)](https://tex.z-dn.net/?f=%5Cto%20P%28x%2Cn%29%20%3D%20n_%7BC%7D_x%20%5Ctimes%20p%5Ex%20%5Ctimes%20%281-p%29%5E%7B%28n-1%29%7D%5C%5C%5C%5C%5Cto%20P%28x%20%5Cgeq%208%29%20%3D%201%20-%20P%28%20%5Cleq%207%29)
Calculating the excel formula:
![=BINOM.DIST(7,10,0.50,TRUE)](https://tex.z-dn.net/?f=%3DBINOM.DIST%287%2C10%2C0.50%2CTRUE%29)
![\to P(x \geq 8) = 1 - 0.9453\\\\ \to P(x \geq 8) = 0.0547](https://tex.z-dn.net/?f=%5Cto%20P%28x%20%5Cgeq%208%29%20%3D%201%20-%200.9453%5C%5C%5C%5C%20%5Cto%20P%28x%20%5Cgeq%208%29%20%3D%200.0547)
