Which box shows a relationship where the constant of proportionality is 64?

Sever21 [200]

Answer:

Step-by-step explanation:

Constant of proportionality = $\frac{y}{x}$

Let's find out which if the boxes will give us 64 as constant of proportionality.

A. $\frac{y}{x} = \frac{11}{2} = 5.5$ ≠ 64

B. $\frac{y}{x} = \frac{5}{15} = \frac{1}{3}$ ≠ 64

C. $\frac{y}{x} = \frac{16}{\frac{1}{4}} = 16*\frac{4}{1} = 64$ ≠ 64

D. $\frac{y}{x} = \frac{\frac{3}{7}}{3} = \frac{3}{7}*\frac{1}{3} = \frac{1}{7}$ ≠ 64

E. $\frac{y}{x} = \frac{2}{-10} = -\frac{1}{5}$ ≠ 64

F. $\frac{y}{x} = \frac{21}{6} = \frac{7}{2}$ ≠ 64

G. $\frac{y}{x} = \frac{4}{8} = \frac{1}{2}$ ≠ 64

From the boxes given, box C is the only box that shows us a relationship where the constant of proportionality is 64.

The mean is the average . the sum of number over the number of observation

x1=525

x2=487

s.d1=59.42

s.d2=51.74

n1=16

n2=12 $\alpha =0.05$

Determine the hypothesis

$H_{0}:$ u1≤u2

$H_{a} :u1>u2$

find the degree of freedom $(\frac{s1^2}{n1} +\frac{s2^2}{n2} )^2/(\frac{s1^2}{n1} )^2/n1-1+(s2^2/n2)^2/n2-1\\\\(\frac{59.42^2}{16} +\frac{51.7476^2}{12} )^2/(\frac{59.42^2}{16} )^2/16-1+(51.74^2/12)^2/12-1$

p-value is the probability of obtaining the value of the test statistics. In the column of t-value in the row df=25

0.025<P<0.05

if the P value is actually less than or the same as the significant level, then the null hypothesis is rejected

P<0.05 rejected H

Determine the solution to the given system of equations. -2 equals negative y minus x. Y equals negative 1 minus x

elena-s [515]

Answer:

The system of equations has no solutions

Step-by-step explanation:

Here, we want to solve the system of equations simultaneously;

-2 = -y - x

y = -1 - x

Substitute the second into the first

-2 = -(-1-x) - x

-2 = 1 + x - x

We can see that the system has no solutions
