Area of the circle is 78.5 sq. units.
<u>Step-by-step explanation:</u>
Circumference of the circle = 31.4 units
2 π r = 31.4 units
2 × 3.14 ×r = 31. 4 units
r = 31.4 / (2×3.14)
= 5 units.
Area of the circle = π r² = 3.14 × 5 × 5 = 78.5 sq. units.

I do suppose that you refer to adding these quantities:
6/1 + 21 = 6 + 21 = 27
<span>and
6/10 + 21
</span>= 3/5 + 21
= 3/5 + 105/5
<span>= 108/5</span>
Answer:
Following are the solution to the given question:
Step-by-step explanation:
The population std. dev of the dog weight=8
Calculating the payout w s.t:
![E[netpay]=0=(-5) \times 0.9544+w\times (1-0.9544)\\\\ w =(5 \times \frac{0.9544}{1-0.9544}) =\$ 104.65](https://tex.z-dn.net/?f=E%5Bnetpay%5D%3D0%3D%28-5%29%20%5Ctimes%200.9544%2Bw%5Ctimes%20%281-0.9544%29%5C%5C%5C%5C%20w%20%3D%285%20%5Ctimes%20%5Cfrac%7B0.9544%7D%7B1-0.9544%7D%29%20%3D%5C%24%20104.65)
therefore, we assume that the weight of the dog is a normal distribution with std. deviation that is 8.
Answer:
Yeah im sure you wont get 3 heads for all coins it would usually be like 1 tails, 2 tails or 3 tails :/?

Answer:
140 coins
Step-by-step explanation:
To calculate the total number of coins Kate have in her collection, we can use the rule of three:
The problem says that 7 of her coins are equivalent of 5% of her entire collection, and we want to know the total number of coins (100%) of her collection. So, if 7 coins are 5%, how much coins are 100%:
7 -> 5%
X -> 100%
7/X = 5/100
X = 100*7/5 = 140 coins
