Y=x+2 y=-3X <br><br>solve system of equations algebraically <br>

goblinko [34]

Answer:

(x,y) = -1/2 , 3/2

Step-by-step explanation:

Let y = x +2 ----- (1)

y = -3x ------ (2)

Put equal both sides x +2 = -3x

x = -3x -2

x +3x = -2

4x = -2

x = -1/2 Put it in 2nd equation

Y = -3 (-1/2)

y = 3/2

so (x,y) = -1/2 , 3/2

Hope you got it.

The lengths of human pregnancies are normally distributed with a mean of 268 days and a standard deviation of 15 days. What is t

AfilCa [17]

Answer: A. 0.0164

Step-by-step explanation:

Given : The lengths of human pregnancies are normally distributed with a mean $\mu=268\text{ days}$

Standard deviation : $\sigma=15\text{ days}$

Let X be the random variable that represents the length of pregnancy of a randomly selected human .

z-score : $z=\dfrac{X-\mu}{\sigma}$

For X = 300

$z=\dfrac{300-268}{15}\approx2.13$

Now, the probability that a pregnancy last at least 300 days will be :-

$P(X\geq300)=P(z\geq 2.1333)=1-P(z$

Hence, the probability that a pregnancy last at least 300 days =0.0164

kobusy [5.1K]

Answer:

aₙ=(-2)ⁿ*2.

Step-by-step explanation:

1) -4*(-2)=8; 8*(-2)=-16; -16*(-2)=32, ...

2) the required equation is:

aₙ=(-1)ⁿ*2ⁿ*2; ⇒ aₙ=(-2)ⁿ*2 or aₙ=(-1)ⁿ*2ⁿ⁺¹.
