In a genetics experiment on peas, one sample of offspring contained 376 green peas and 117 yellow peas. Based on those results

scZoUnD [109]

Answer:

Step-by-step explanation:

Given that in a genetics experiment on peas, one sample of offspring contained 376 green peas and 117 yellow peas.

Total no of peas = 376+117=493

No of green peas = 376

Probability of selecting a green pea = $\frac{376}{493} =0.7627$

Yes it is reasonably close to 3/4 = 0.75 since difference is only 0.0127 negligible.

Calculate an estimate of a square root of 119 + 120i

uysha [10]

Answer:

Step-by-step explanation:

Given

z=119+120 i

Let $\sqrt{119+120 i}=p+iq$

Squaring both sides

$119+120 i=p^2-q^2+2ipq$

Comparing real and imaginary part

Re(LHS)=Re(RHS)

$119=p^2-q^2$ -----------1

comparing Im(LHS)=Im(RHS)

120=2pq

$q=\frac{60}{p}$

Substitute q in 1

$119=p^2-(\frac{60}{p})^2$

$p^4-119p^2-(68)^2=0$

Let $x=p^2$

$x^2-119x-4624=0$

$x=frac{119\pm \sqrt{119^2+4\times 4624}}{2}$

$x=\frac{119\pm 180.71}{2}$

we take only Positive value because $p^2=x$

x=149.85

$p^2=149.85$

thus $p=\pm 12.24$

$q=\mp 4.90$

thus $\sqrt{119+120 i}=\pm (12.24+i 4.90)$

Answer:

20.8

Step-by-step explanation:

The chord with length x is bisected by the perpendicular segment.

Use the Pythagorean theorem to find the length of half of x.

Let's call half of x, y.

y^2 + 6^2 = 12^2

y^2 = 144 - 36

y^2 = 108

y = sqrt(108)

x = 2y = 2sqrt(108)

x = 20.8
