Answer:
3. It is likely.
Step-by-step explanation:
Let's assume the dartboards circles have radius of r, 2r, 3r and 4r from inner side
<u>Then the areas covered will be as:</u>
- point 20 = πr² = S
- point 15 = π(2r)² - πr² = 3πr² = 3S
- point 1 0 = π(3r)² - π(2r)² = 5πr² = 5S
- point 5 = π(4r)² - π(3r)² = 7πr² = 7S
Total area of the dartboard is S+3S+5S+7S = 16S
The area of point 5 is 7S. And the area of non- 5 point is 16S - 7S = 9S
The probability of scoring at least 10 points is:
As it is between 1/2 and 1, the probability is in 'likely' region
<u>So the correct answer choice is:</u> 3. It is likely
Answer:$4449.6.
Step-by-step explanation:
You deposit $2700 into a bank account paying 64.8% simple interest per year. You left the money in for 1 year. Find the interest earned and the amount at the end of those 1 year?
Result:
The interest is $1749.6 and the amount is $4449.6.
Explanation:
STEP 1: Find an interest by using the formula , where I is interest, P is total principal, i is rate of interest per year, and t is total time in years.
In this examplee P = $2700, i = 64.8% and t = 1 years, so
STEP 2: Find an amount by using the formula .A =P+I
Since P = $2700 and I = $1749.6 we have
Answer:
y= 73 degrees
x=34 degrees
Step-by-step explanation:
180-107=73
y= 73 degrees
73+73= 146
180-146=34
x=34 degrees
Answer:
6.3
Step-by-step explanation:
1. 25 - 2n = n + 6
2. 25 = 3n + 6
3. 3n = 19
4. n = 6.3
