Answer:

y=0.5x+4

Step-by-step explanation:

0.5x= y-4

add 4 on both sides

and then you get:

y=0.5x+4

Answer:

y = 0.5x + 4, or y = 1/2x + 4 (if you prefer fractions)

Step-by-step explanation:

y = mx + b (slope intercept form / standard form) ; m = 0.5 or 1/2, b = 4.

m = linear coefficient/slope(denoted by a in a 1 degree binomial)

b = constant coefficient / y-intercept (denoted by b in a 1 degree binomial)

to convert this equation into a standard form equation. You need to isolate y and leave the coefficients on the other side.

0.5x = y - 4

0.5x (+4) = y - 4 (+4)

0.5x + 4 = y

y = 0.5x + 4

A particular employee arrives at work sometime between 8:00 a.m. and 8:30 a.m. Based on past experience the company has determin

Gala2k [10]

Answer:

0.3333 = 33.33% probability that the employee will arrive between 8:15 a.m. and 8:25 a.m.

Step-by-step explanation:

A distribution is called uniform if each outcome has the same probability of happening.

The uniform distributon has two bounds, a and b, and the probability of finding a value between c and d is given by:

$P(c \leq X \leq d) = \frac{d - c}{b - a}$

A particular employee arrives at work sometime between 8:00 a.m. and 8:30 a.m.

We can consider 8 am = 0, and 8:30 am = 30, so $a = 0, b = 30$

Find the probability that the employee will arrive between 8:15 a.m. and 8:25 a.m.

Between 15 and 25, so:

$P(15 \leq X \leq 25) = \frac{25 - 15}{30 - 0} = 0.3333$

0.3333 = 33.33% probability that the employee will arrive between 8:15 a.m. and 8:25 a.m.

tatyana61 [14]

Answer:

Step-by-step explanation:

If the presale price is $x$ ,

then $x*(1-0.30)=8.40\\0.70x=8.40\\x=8.40/0.70=12.0\\$

Thus the presale price is $12.0

We will use the elimination method to solve the following system of

quester [9]

Answer:

x = 3

y = -5

Step-by-step explanation:

It would be very easy to eliminate y by adding the two equations,

4x - 7y = 47

6x + 7y = -17

10x = 30

x = 3 4(3) - 7y = 47

12 - 7y = 47

-7y = 35

y = -5

Check: See if the values work in the second equation

6(3) + 7(-5)

= 18 - 35

= -17 It looks like they work, so we know we have the correct values
