Answer: Choice C) 6x+5y = -20

You have the correct answer. Nice work.

=================================================

Work Shown:

y = (-6/5)x - 4

5y = 5*( (-6/5)x - 4 )

5y = 5*(-6/5)x - 5*4

5y = -6x - 20

6x+5y = -20

-----------

Explanation:

In the second step, I multiplied both sides by 5 to clear out the denominator. Two steps later (step 4), we have 5*(-6/5)x turn into -6x, so the fraction goes away.

In the last step, I added 6x to both sides to get the equation into standard form Ax+By = C. In this case, A = 6, B = 5, and C = -20.

Write an equation in slope - intercept to represent the relationship in the table
Nataly_w [17]
Pick 2 random ascending x values and calculate the difference delta to get the slope
\delta \: x =  - 2 - ( - 1) = 1
so your slope is "1"

and as you can see, that x=0 at y=3, so your y-intercept is 3
thats it, your function is
f(x) = x + 3

Summary information on the heights of 64 bass and 42 tenor singers, all men, in the New York Choral Society is given. The vocal
aleksley [76]

Answer:

Hello your question has some missing information below is the missing information

Sample mean  and Sample standard deviation

Bass 70.99  and   2.52

Tenor 69.41   and  2.79

answer : <em>We will reject H0 </em>

Step-by-step explanation:

<u>Determine whether the population mean height of bass singers > population mean height of tenor singers </u>

n1 = 64 ,   n2 = 42

x1 ( mean ) = 70.99

x2( mean ) = 69.41

S1 ( std 1 ) = 2.52

S2 ( std 2 ) = 2.79

We will perform a two tailed test hence we will state the null and alternate hypothesis

H0 : μ1 > μ2

H1 : μ1 < μ2

significance level = 0.01

next calculate the test statistic

t = 2.96

attached below is the remaining part of the detailed solution

Which statements represent the rules of significant figures? Check all that apply.
maksim [4K]

Answer:

The integers 1, 2, 3, 4, 5, 6, 7, 8, and 9 are always significant.

Zeros in between numbers are always significant.

Step-by-step explanation:

There are three rules by which the number of significant figures can be determined:

  • The digits which are other than the zero are said to be significant figures.
  • Any zero which is present between two significant figure is said to be significant.
  • The zero which appears in the right of the decimal portion in the end is significant. The zero which comes after the decimal is not significant.
