Answer:

Step-by-step explanation:

slope intercept form is y = mx + b

b is the y intercept ( crossing y axis value).... by inspection b = -4

m is the slope of the line, Slope = m = 1/4 note: the slope is positive

the slope equals the 'rise' over 'run'

if the line moves up the slope is positive, if the line moves down the slope is negative

the rise is how many y units does the line go 'up' or 'down'

the run is how many x units does the line go 'left' or 'right'

the rise = 1 Y unit

the run = 4 X units

y = mx + b m =1/4 b = -4

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

y = (1/4)x - 4

graph a line stating at y = -4 and going up (rising) to the right ONE Y Unit for every FOUR X units (the run)

liberstina [14]

Hi there, we are going to set up a porportion. 640 miles/25 hours ÷ 25/25. That would equal 25.6 miles/1 hour. Therefore, the answer is 25.6 miles per hour.

In an election, the population consists of the people who voted. Although there is overall data on how the population voted, the

Answer:

Answer:

P(A) = 0.39

Step-by-step explanation:

We are given;

P(W|A) = 0.7

P(W|A^c ) = 0.3

We are told that 60% of the respondents said they voted for A. Thus;

P(A|W) = 60% = 0.6

Now, using the principle of drawing lots, we can be able to find the probability of the event that they are willing to participate in the exit poll which is P(W).

Thus;

P(W) = [P(W|A) × P(A)] +[P(W∣A^c) × P(A^c)]

Now, P(A^c) can be expressed as 1 - P(A)

Thus, we now have;

P(W) = [P(W|A) × P(A)] + [P(W∣A^c) × (1 - P(A)]

Plugging in the relevant values gives;

P(W) = 0.7P(A) + 0.3(1 - P(A))

P(W) = 0.7P(A) + 0.3 - 0.3P(A)

P(W) = 0.3 + 0.4P(A)

Now,using Baye's theorem, we can find an expression for P(A|W)

Thus;

P(A|W) = [P(A ∩ W)]/P(W)

This can be further expressed as;

P(A|W) = [P(A) × P(W|A)]/P(W)

Plugging in relevant values, we have;

0.6 = 0.7P(A)/(0.3 + 0.4P(A))

Cross multiply to get;

0.6(0.3 + 0.4P(A)) = 0.7P(A)

0.18 + 0.24P(A) = 0.7P(A)

0.18 = 0.7P(A) - 0.24P(A)

0.46P(A) = 0.18

P(A) = 0.18/0.46

P(A) = 0.39

What is the value of the expression 2 + 3^2 * (5 -1)

alexgriva [62]

Answer:

Step-by-step explanation:

We are to solve for the expression;

2 + 3² × (5 - 1)

We should aply BODMAS here!

So starting with the brackets;

2 + 3² × 4

Then solving the multiplication part;

3² × 4 = 9 × 4 = 36

Finally adding the integers;

2 + 36 = 38
