Answer:

34x-5 = 2x/27+10

or, 34x-5=(2x+270)/27

or, 918x - 135=2x+270

or, 918x-2x=270+135

or, 916x= 405

or, x = 0.44

A genetic experiment involving peas yielded one sample of offspring consisting of 430 green peas and 155 yellow peas. Use a 0.05
Dimas [21]

Answer:

the null and alternative hypothesis are

H_{0}: p=0.24

H_{a}: p≠0.24

Test statistic is 1.416.

P-Value is 0.1568

We fail to reject the null hypothesis under 0.05 significance level

<em>At 0.05 significance</em> we cannot say that the proportion of offspring peas will be yellow is not 0.24 (24%)

Step-by-step explanation:

Let p be the proportion of offspring peas will be yellow. Then,

H_{0}: p=0.24

H_{a}: p≠0.24

test statistic can be calculated as

z=\frac{p(s)-p}{\sqrt{\frac{p*(1-p)}{N} } } where

  • p(s) is the sample proportion of yellow offspring peas (\frac{155}{155+430} =0.265
  • p is the proportion of yellow offspring peas assumed under null hypothesis. (0.24)
  • N is the sample size (585)

Test statistic is z=\frac{0.265-0.24}{\sqrt{\frac{0.24*0.76}{585} } } ≈ 1.416.

Using z-table, we can find that P-Value is 0.1568

We fail to reject the null hypothesis under 0.05 significance level since 0.157>0.05

We can conclude that <em>at 0.05 significance</em> we cannot say that the proportion of offspring peas will be yellow is not 0.24 (24%)

Solve the system of equations
Nadya [2.5K]

So we have the equations:

    y - 4x = 2 --- equation 1

   5y - 2x = 1 --- equation 2

(equation 2) * 2

  10y - 4x = 2 --- equation 3

 

(equation 2) - (equation 3)

 -9y = 0   so y= 0 and thus x = -1/2

Hope that helps!
