In the word "Mathematical"
Vowels are "a", "e", "a", "i", "a" from left to right
Consonants are "m", "t", "h", "m", "t", "c", "l"
5 vowels and 7 consonants of total 12 letters
So the probability of picking a vowel is
Hi! To find the surface area of a cylinder, you need to find the surface area of the base, and then the surface area of the rectangular prism that "wraps around" the cylinder.
The area of a circle: A=pi*r^2
A=3.14*3.7^2
A≈43.00
Multiply this by 2 because there are 2 circles
Combined Area of Circles = 86
Circumference of a circle = C=2pi*r (this is for the width of the rectangle)
C=2(3.14)(3.7)
C=23.236
C=W
W=23.236
W*L=A
23.236 * 7.1=A
A≈165
Now lets add them together!
86cm^2+165cm^2= 251 cm squared
The probability is 3/10. Reason being is that between 1 and 10, there are three numbers that are a multiple of 3. 3 6 and 9. since there are 10 options, you have a 3 in 10 chance of getting a multiple of 3
All these equations are in the form of ax^2 + bx + c = 0, where a, b, and c are some numbers. the discriminants of equations like this are equal to b^2 - 4ac. if the discriminant is negative, there are two imaginary solutions. if the discriminant is positive, there are two real solutions. if the discriminant is 0, there is one real solution.
<span>x^2 + 4x + 5 = 0
</span>b^2 - 4ac
4^2 - 4(1)(5)
16-20
-4, two imaginary solutions.
<span>x^2 - 4x - 5 = 0
</span>b^2 - 4ac
(-4)^2 - 4(1)(-5)
16 + 20
36, two real solutions.
<span>4x^2 + 20x + 25 = 0
</span>b^2 - 4ac
20^2 - 4(4)(25)
400 - 400
0, one real solution.
