Answer:
Hello! answer: 96
Step-by-step explanation:
Formula for finding area in squares: base × height
Formula for finding area in triangles: base × height ÷ by 2
8 × 8 = 64 8 × 8 ÷ 2 = 32 64 + 32 = 96 therefore the area is 96 HOPE THAT HELPS!
The total cost would be $191.49
Not rounded up so round it up to .50 if you have to :)
<span>Discriminant is 28 (c)
First get the equation into the form: Ax^2 + Bx + C = 0 (the quadratic equation)..
By subtracting 10x both sides (to get it on the other side)..
9x^2 + 2 = 10x
9x^2 - 10x + 2 = 10x - 10x
9x^2 - 10x + 2 = 0
Now the discriminant is: b^2 - 4ac
The quadratic equation is Ax^2 + Bx + C = 0
Here, A = 9, B = -10 and C = 2
(-10)^2 - 4 (9)(2)
= 100 - 4 (18)
= 100 - 72
= 28</span>
Answer: No
Step-by-step explanation: If flipped 400 times and 222 times are heads, then there is a 55.5% chance it will be heads. If flipped 10,000 times, then there should be 5550 heads.
Here we have selected positive numbers from 2 to 18 so there are total 17 numbers with us.
Now the prime numbers between 2 and 17 are
2, 3, 5, 7, 11, 13, 17
So there are 7 prime numbers between 2 to 18
We have to find the probability of selecting prime numbers between 2 to 18
Probability = Outcomes of interest / All possible outcomes
Probability prime = 7/17
Probability prime = 0.4117
So probability of getting prime number is 0.4117
