Answer:

y = -\frac{7}{10}(x + 8)

Step-by-step explanation:

To write the equation of a line, substitute m = -7/10 and the point (-8,0) into the point slope formula.

y - y_1=m(x-x_1)\\y - 0 = -\frac{7}{10}(x --8)\\y = -\frac{7}{10}(x + 8)

Answer:

6(x-3)

Step-by-step explanation:

the common number for 6 and 18 is 6 so if you extract that from the expression then it turns to 6(x-3) which cannot be factored further

Solve 2x2 − 8x = −7.
leva [86]
\sf 2x^2 - 8x = - 7  \\  \\ Subtract \ -7 \ from \ both \ sides \ of \ the \ equation. \\  \\ 2x^2 - 8x - (-7 ) = - 7 - (-7)  \\  \\ 2x^2 - 8x + 7 = 0  \\  \\ Use \ quadratic \ formula \ a = 2, b = -8, c = 7 \\  \\ x =  \dfrac{- b \pm \sqrt{b^2- 4ac} }{2a}  \\  \\  \\ x =  \dfrac{-(-8) \pm \sqrt{(-8)^2 - 4 (2) (7) } }{2(2)}  \\  \\ x =  \dfrac{8 \pm  \sqrt{8} }{4}  \\  \\ x = 2 +  \frac{1}{2}\sqrt{2} \ or \ x = 2 +  \frac{-1}{2}  \sqrt{2}

genetic experiment with peas resulted in one sample of offspring that consisted of green peas and yellow peas. a. Construct a ​%
Andreas93 [3]

Complete Question

A genetic experiment with peas resulted in one sample of offspring that consisted of 432 green peas and 164 yellow peas. a. Construct a 95% confidence interval to estimate of the percentage of yellow peas. b. It was expected that 25% of the offspring peas would be yellow. Given that the percentage of offspring yellow peas is not 25%, do the results contradict expectations?

Answer:

The  95%  confidence interval is  0.2392  <  p < 0.3108

No, the confidence interval includes​ 0.25, so the true percentage could easily equal​ 25%

Step-by-step explanation:

From the question we are told that

  The total sample size is  n  =  432 + 164 =596

   The  number of  offspring that is yellow peas is y =  432

   The  number of  offspring that is green peas   is g =  164

   

The sample proportion for offspring that are yellow peas is mathematically evaluated as

        \r p  =  \frac{ 164 }{596}

        \r p  =  0.275

Given the the  confidence level is  95% then the level of significance is mathematically represented as

       \alpha  =  (100 - 95)\%

      \alpha =  5\%  =  0.0 5

The  critical value of  \frac{\alpha }{2} from the normal distribution table is  

      Z_{\frac{\alpha }{2} } = 1.96

Generally the margin of error is mathematically evaluated as

        E =  Z_{\frac{\alpha }{2} } * \sqrt{\frac{\r p (1- \r p )}{n} }

=>      E = 1.96 * \sqrt{\frac{0.275 (1- 0.275 )}{596} }

=>      E =  0.0358

The  95%  confidence interval is mathematically represented as

      \r p - E  <  p < \r p + E

=>   0.275 -  0.0358  <  p < 0.275 +  0.0358

=>   0.2392  <  p < 0.3108
