Answer:

f(x)=x3

Step-by-step explanation:

If you meant f(x)=x3 by f(x)=x^3 then that would be a cubic equation and not linear?

Which line is parallel to the line that passes through the points (1,7) and (-3, 4)? A.y=-3/4x-5 B.y=3/4x+1 C.y=4/3x-8 D. y=11/4

mixer [17]

Answer:

The Line p

y= 3/4x+ 6.25

Step-by-step explanation:

The points given changed 4 right and 3 up, giving a slope of .75

plug this slope into (1,7) to get the y-intercept. This shows the intercept at 6.25.

A hypothesis will be used to test that a population mean equals 10 against the alternative that the population mean is more than

PilotLPTM [1.2K]

Answer:

A) 2.58

B) 1.96

C) 1.65

Step-by-step explanation:

A hypothesis used to test that

$H_o : \mu = 10$

against the alternatives $H1 : \mu$ not equal to 10

if null hypothesis is true, then distribution of test statics follow

$Zo = \frac{\bar x - \mu}{\frac{\sigma}{\sqrt{n}}}$

for two sided alternatives hypothesis $( H1: \mu \neq 7)$ , then P value is

$P = 2[1- \phi(\left | Zc \right |)]$ (1)

a)significance level $\alpha = 0.01$

from 1 eq we get

$\pi (\left | Zc \right |) = P(Zo$

Therefore $\left | Zc \right | = 2.58$ FROM Z TABLE

B) significance level $\alpha = 0.05$

from 1st equation we get

$\pi (\left | Zc \right |) = P(Zo < \left | Zc \right |) = 1 - \frac{0.05}{2} = 0.975$

Therefore $\left | Zc \right | = 1.96$ FROM Z TABLE

C) significance level $\alpha = 0.10$

from 1 eq we get

$\pi (\left | Zc \right |) = P(Zo$

Therefore $\left | Zc \right | = 1.65$ FROM Z TABLE

BlackZzzverrR [31]

Answer:

111

Step-by-step explanation:

150 + 20 = 170

170 - 52 = 118

118 + 23 = 141

141 - 16 = 125

125 + 14 = 139

139 - 28 = 111
