Answer:

60 = a

Step-by-step explanation:

⅔ of 30 is 20; ½ of 60 is 30. So together, you have 30 + 20 = 50.

I am joyous to assist you anytime.

1/2a + 2/3(30)= 50
1/2a + 20 = 50
1/2a= 50-20
1/2a= 30
A= 30(2)
A= 60

The solution is 60.

Hope this helps!

Answer:

More than 50% would germinate

Step-by-step explanation:

Given that in the production of a plant, a treatment is being evaluated to germinate seed. From a total of 60 seed it was observed that 37 of them germinated

Let us check whether more than 50% will germinate using hypothesis test

$H_0: p = 0.50\\H_a: p>0.50\\$

(right tailed test)

Sample proportion p = $\frac{37}{60} =0.617\\q = 0.383\\Std error = \sqrt{\frac{pq}{n} } =0.0628$

p difference = 0.117

Test statistic Z = p difference/std error = 1.864

p value =0.0312

Since p value <0.05 our significance level of 5% we reject null hypothesis

It is possible to claim that most of the seed will germinate (i.e. more than 50%)

$\frac{y-y}{x-x}$ =gradient
$\frac{7+3}{-2+4} = 5$
Perpendicular gradient therefore is $\frac{-1}{5}$

With this info, y-y1=m(x-x1)
5(y-8)=-1(x-6)
5y-40=-x+6
5y=-x+46
$y= \frac{-x}{5} + 9.2$
