Answer:

Step-by-step explanation:

2 is 40% of 5, so if we stay within this data, then she will win 40% of the next 20 games she plays. 40% of 20 is 8, so she will win 8 games out of 20

06. Kristen can run at 15km/hr and walk at 5 km/hr. She completed a 42 km marathon in 4 hours. What distance did Kristen run dur

Mrac [35]

Let x be the time she ran and y be the time she walked

then distance ran = 25x and distance walked = 5y

so 15x + 5y = 42

and x + y = 4

* second equn. by -5:-

-5x - 5y = -20

add this to the first equn:0

10x = 22
x = 2.2

distance she ran = 2.2 * 15 = 33 km

The graph of f(x) = (0.5) is replaced by the graph of g(x) = (0.5)* - k. If g(x) is obtained by shifting f(x) down by 3 units, t

Ghella [55]

Answer:

$k = 3$

Step-by-step explanation:

Given

$f(x) = 0.5x$

$g(x) = 0.5x - k$

Required

$Find\ k$

Initial expression of f(x) is $f(x) = 0.5x$

From the question; we understand that f(x) was shifted down by 3 units;

This implies that

$New\ f(x) = 0.5x - 3$

Also from the question; we understand that this new f(x) is equivalent to g(x);

In other words;

$New\ f(x) = g(x)$

Substitute $New\ f(x) = 0.5x - 3$ and $g(x) = 0.5x - k$

This gives

$0.5x - 3 = 0.5x - k$

<em />

Subtract 0.5x to both sides

$0.5x - 3 - 0.5x = 0.5x - k - 0.5x$

Rearrange

$0.5x - 0.5x - 3 = 0.5x - 0.5x- k$

$-3 = -k$

Multiply both sides by -1

$-3 * -1 = -k *-1$

$3 = k$

$k = 3$

elena-s [515]

Answer:

7.92% probability that a particular death is due to a traffic accident

Step-by-step explanation:

The relative frequency approach to find the probability that a particular death is due to a traffic accident is the number of deaths due to traffic accidents divided by the total number of deaths.

We have that:

624 deaths from traffic accidents

7883 total deaths.

$p = \frac{624}{7883} = 0.0792$

7.92% probability that a particular death is due to a traffic accident
