Step-by-step explanation:

27 X 4/3y=36y

Answer:

When you find the y value and multiply it by 4/3, it equals 36.

Step-by-step explanation:

[tex] \frac{ \frac{4}{3}y }{ \frac{4}{3} } = \frac{ 36 }{ \frac{4}{3} } \\ y = 27[/tex]

[tex] \frac{4}{3} (27) = 36 \\ 36 = 36[/tex]

Step-by-step explanation:

First, expand out the brackets

2 x 1.6a = 3.2a

2 x 0.7 = 1.4

Therefore 3.2a - 1.4 = 8.2

Now solve to find a

3.2a - 1.4 = 8.2

3.2a = 9.6

a = 3

In sample of 200 economists, 147 choose the FRED database as the most popular economic database. Calculate the margin of error for a 97% confidence interval.

Answers

Answer: 0.9577

Step-by-step explanation:

Formula for margin of error (E):

[tex]E= z^*\sqrt{\dfrac{p(1-p)}{n}}[/tex] , where p = sample proportion, n =sample space, z* critical z-value.

Given: n= 200

[tex]p=\dfrac{147}{200}[/tex]

Critical value for 97% confidence level = 2.17

Margin of error (E) = [tex]2.17\sqrt{\dfrac{147}{200}(1-\dfrac{147}{200})}[/tex]

[tex]=2.17\sqrt{\dfrac{147}{200}(\dfrac{53}{200})}\\\\=2.17\times \sqrt{0.194775}\\\\=2.17\times0.441333207452\approx0.9577[/tex]

Hence, the margin of error for a 97% confidence interval = 0.9577

Find an equation of the line with the given y-intercept and slope m.
3.2, m = -2.4
The equation of the line is
(Type your answer in slope-intercept form.)

Answers

Answer:

y = -2.4x + 32

or y = -12/5x + 16/5

or 12x + 5y = 16

Step-by-step explanation:

slope intercept form is y = mx + b

replace the m with the slope and b with y intercept

y = -2.4x + 3.2

with fractions instead of decimals its

y = -12/5x + 16/5

you could also write it like this I think

12x + 5y = 16

whatever way you were taught, do it
