4x-11=3.2x+13. Write the lesser solution first. Round to the nearest tenth if needed

notsponge [240]

Answer:

The answer is (30, 109)

Step-by-step explanation:

In this problem we need to find the intersection point between the lines

y = 4x-11

and

y = 3.2x+13

We can easily solve this problem by plotting both lines in a graphing calculator and finding the intersection point.

Please see attached picture.

The answer is (30, 109)

A research team conducted a study showing that approximately 30% of all businessmen who wear ties wear them so tightly that they

photoshop1234 [79]

Answer:

a) 0.9998

b) 0.9979

c) 0.7

d) 0.9155

Step-by-step explanation:

P( people who wear their ties tightly ) = 0.3

P( people who do not wear their ties tightly ) = 1 - 0.3 = 0.7

sample size ( n ) = 30

<em>Given that the events are independent and there are only two outcomes we will apply Binomial distribution </em>

<u>a) P( at least one tie is too tight ) </u>

P ( x ≥ 1 ) = 1 - P ( x < 1 ) = 1 - P ( x = 0 )

= 1 - 0.00002 = 0.9998 ( excel function: 1 - BINOMDIST(0,30,0.3,0) )

<u>b) P( more than two ties are too tight )</u>

P ( x > 2 ) = 1 - P ( x ≤ 2 ) = 1 - BINOMDIST(2, 30, 0.3, 1 )

= 1 - 0.002113178

= 0.9979

<u>c) P ( no tie is tight )</u>

P ( x = 0 ) = 0.7

<u>d) P( at least 18 ties are not too tight ) i.e. ( P = 0.7 )</u>

P ( x ≥ 18 ) = 1 - P( x ≤ 17 )

= 1 - BINOMDIST ( 17, 30, 0.7, 1 )

= 1 - 0.08447006

= 0.9155

What is the system of equations represented by the tables?

lina2011 [118]

Answer:

C.

y = -3x - 1

y = 3x + 2

Step-by-step explanation:

Find the slope (m) and y-intercept (b) of each table to write an equation for each.

✔️First table:

Find the slope (m) = change in y/change in x

Using any two pair of values, say (0, -1) and (1, -4),

Slope (m) = (-4 - (-1))/(1 - 0) = -3/1

m = -3

Find the y-intercept:

y-intercept is the value of y when x = 0

From the table, y = -1 when x = 0. Therefore,

y-intercept (b) = -1

To write an equation for table 1, substitute m = -3 and b = -1 into y = mx + b

Equation for table 1:

y = -3x - 1

✔️ Second table:

Find the slope (m) = change in y/change in x

Using any two pair of values, say (0, 2) and (1, 5),

Slope (m) = (5 - 2)/(1 - 0) = 3/1

m = 3

Find the y-intercept:

y-intercept is the value of y when x = 0

From the table, y = 2 when x = 0. Therefore,

y-intercept (b) = 2

To write an equation for table 1, substitute m = 3 and b = 2 into y = mx + b

Equation for table 1:

y = 3x + 2
