Answer:

The translation for the above map points is 8 units up and 5 units left.

Step-by-step explanation:

$D(7,-3)\rightarrow D'(2,5).$

The translation for the above map points is 8 units up and 5 units left.

Step 1: 8 units up

$D(7,-3)\rightarrow$ (Add 8 to y co-ordinate) $(7,-3+8)\rightarrow (7,5)$

Step 2: 5 units left

$(7,5)\rightarrow$ (subtract 5 from x-co-ordinate) $(7-5,5)\rightarrow D'(2,5)$

Answer:

$P(X = x) = C_{8,x}.(0.4)^{x}.(0.6)^{8-x}$

In which x is the number of which we want to find the probability.

Step-by-step explanation:

For each traffic fatality, there are only two possible outcomes. EIther it involved an intoxicated or alcohol-impaired driver or nonoccupant, or it didn't. Traffic fatalities are independent of other traffic fatalities, which means that the binomial probability distribution to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

In which $C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by the following formula.

$C_{n,x} = \frac{n!}{x!(n-x)!}$

And p is the probability of X happening.

The probability is .40 that a traffic fatality involves an intoxication or alcohol-impaired driver or nonoccupant.

This means that $p = 0.4$

Eight traffic fatalities

This means that $n = 8$

Find the probability that the number which involve an intoxicated or alcohol-impaired driver or nonoccupant is

This is P(X = x), in which x is the number of which we want to find the probability. So

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

$P(X = x) = C_{8,x}.(0.4)^{x}.(0.6)^{8-x}$

Draw a model and write an equation to represent 4 times as many as 3 is 12

WINSTONCH [101]

Hmmm the easiest way I can imagine to explain this is as follows:

4 times 3 is like 3 added to itself 4 times.

so 4×3= 3+3+3+3= 12. I'm not sure if that's what you meant by drawing a model though.

If f(x) = 5x + 40, what is f(x) when x = -5?<br> 0 -9<br> 0 -8<br> ОО

Kazeer [188]

When you move the 40 to the other side ur subtracting and so -40 - 5 is -45, after you divide -45 and 5 and get -9.

Write an equation of the line that passes through (−3,3) and is perpendicular to the line 2y=8x−6.

fiasKO [112]

Answer:

4y = -x + 9

Step-by-step explanation:

2y = 8x - 6

Divide through by 2:-

y = 4x -3 so the slope of this line = 4

Slope of the line perpendicular to this = -1/4

So using the point/slope form of an equation of a line and the point (-3,3) we have:-

y - 3 = -1/4(x - -3)

y = -1/4x - 3/4 + 3

y = -1/4 x + 9/4 Multiply through by 4:-

4y = -x + 9
