Answer:

The probability of choosing tiles which sum is 12 is 1/21

Step-by-step explanation:

The numbers we have is 1.2,3,4,5,6 and 7

The sum we are looking at is 12. The only sum that can give us this sum is the addition of 7 and 5

There are only two ways we can make this selection if order matters.

Either we pick 5 first then 7 second or 7 first and 5 second

The probability of picking a 5 first will be 1/7, since it is without replacement , the probability of picking a 7 next will be 1/6

The joint probability here would thus be 1/7 * 1/6 = 1/42

In the other second case where we are picking a 7 first and a 5 second, the probability here will be the same as first just that we reversed the other. Hence, the probability here is also 1/42

Now, the probability of either of the two orders happening will be 1/42 + 1/42 = 2/42 = 1/21

Your friend says that 14.5% is same as the fraction 29/200. explain whether your friend is correct or incorrect by comparing the
OlgaM077 [116]

14.5% = 0.145

Step-by-step explanation:

The term 'percent' (%) actually means per 100. So when you say 14.5% it means 14.5 per 100. So when you put that into an equation it actually means:

So when you solve it, 14.5% is actually 0.145 and not 14.5.

Your friend is then incorrect because:

14.5% ≠ 14.5

map of a city uses the scale 1 cm equals 50 m. On the​ map, South Street is 25 cm long. If there is a traffic cone at the start
aivan3 [116]

Answer:

125 traffic cones

Step-by-step explanation:

In order to find the total number of meters, we can set up a proportion to find based on the ration of cm to m:

\frac{centimeters}{meters}=\frac{1}{50}=\frac{25}{x}, where 'x' is the number of meters

cross-multiply: x = 25(50) or x = 1250 m

Since there is a cone every 10 m, we can divide the total number of meters by 10:

1250/10 = 125 cones

Suppose f and g are continuous functions such that g(6) = 6 and lim x → 6 [3f(x) + f(x)g(x)] = 45. Find f(6).
aleksandr82 [10.1K]
Since g(6)=6, and both functions are continuous, we have:

\lim_{x \to 6} [3f(x)+f(x)g(x)] = 45\\\\\lim_{x \to 6} [3f(x)+6f(x)] = 45\\\\lim_{x \to 6} [9f(x)] = 45\\\\9\cdot lim_{x \to 6} f(x) = 45\\\\lim_{x \to 6} f(x)=5


if a function is continuous at a point c, then lim_{x \to c} f(x)=f(c), 

that is, in a    c ∈  a continuous interval, f(c) and the limit of f as x approaches c are the same.


Thus, since lim_{x \to 6} f(x)=5, f(6) = 5
