1. A heterozygous white-fruited squash plant is crossed with a yellow-fruited plant, yielding 200 seeds. of these seeds, 110 pro

garri49 [273]

Answer:

Part 1 , not significant

Part II, significant

Step-by-step explanation:

Given that a heterozygous white-fruited squash plant is crossed with a yellow-fruited plant, yielding 200 seeds. of these seeds, 110 produce white-fruited plants while only 90 produce yellow-fruited plants

$H_0: Both colours are equally likely\\H_a: Both colours are not equally likely$

(Two tailed chi square test)

We assume H0 to be true and find out expected

If H0 is true expected would be 100 white and 100 yellow

Chi square = $\Sigma \frac{(O-E)^2}{E} \\=\frac{(110-100)^2}{100} +frac{(90-100)^2}{100} \\=2$

df = 1

p value = 0.152799

Since p value > 0.05 at 5% level we accept that the colours are equally likely

2)

Here observed are 1100 and 900

Expected 1000 & 1000

df = 1

Chi square = $\frac{20000}{100} =200$

p value <0.0001

These results are here statistically significant.

Maths Questions box 51.The function f: R→ R is twice differentiable and for any x ER we have g(x) = f(4-x²), if f'(1) = -5 and f

mrs_skeptik [129]

By the chain rule,

$g(x) = f(4 - x^2) \\\\ \implies g'(x) = -2x f'(4 - x^2) \\\\ \implies g''(x) = -2 f'(4 - x^2) + 4x^2 f''(4 - x^2)$

Observe that

$4 - x^2 = 1 \implies x^2 = 3 \implies x = \pm\sqrt3$

Then

$g''(\sqrt3) = -2 f'(1) + 4\left(\sqrt3\right)^2 f''(1) = -2(-5) + 4(3)(-1) = \boxed{-2}$

50 POINTS. PLZ ANSWER RIGHT

LenKa [72]

Answer:

5 : 6 or $\frac{5}{6}$

Step-by-step explanation:

Given that, I make 5 quarts of tomato sauce from 6 baskets of tomatoes.

Therefore, the ratio of the number of quarts of tomato sauce to the number of the basket of tomatoes will be given by 5 : 6 in the simplest form.

If we want to express the ratio of the number of quarts of tomato sauce to the number of the basket of tomatoes in fraction form then it will be $\frac{5}{6}$ in the simplest form. (Answer)
