Mathematics
1 answer:
vagabundo [1.1K]3 years ago
5 0

Answer:

-7.

Step-by-step explanation:

(x²+t²x+t³+8)`=(x²)`+(t²x)`+(t³)`+(8)`=2x*x'+2t*x+t²*x'+3t²;

x'=\frac{2tx+3t^2}{t^2+2x};

x'(-2;-4)=\frac{2*2*4+3*4}{4-8}=-7.

P=3y/q solve for y make sure to add steps pls
Likurg_2 [28]

Answer:

Solving for y gives:

y = \frac{pq}{3}

Step-by-step explanation:

Linear equations are the equations that are degree one equations. When it is asked to solve an equation for a specific variable that means that the specified variable has to be isolated on one side of the equation i.e. in the given question solving for y means isolating y on one side of the equation.

Given equation is:

p = \frac{3y}{q}

Multiplication property of equality(Multiplying both sides by q)

p*q = \frac{3y}{q} * q\\pq = 3y

Division property of equality(Dividing both sides by 3)

\frac{pq}{3} = \frac{3y}{3}\\\frac{pq}{3} = y

Hence,

Solving for y gives:

y = \frac{pq}{3}

The mean incubation time of fertilized eggs is 23 days. Suppose the incubation times are approximately normally distributed with
Anna007 [38]

Answer: the incubation time that separates the bottom 2.5​% from the rest of the incubation times is 24.96 days.

Step-by-step explanation:

Suppose the incubation times are approximately normally distributed, we would apply the formula for normal distribution which is expressed as

z = (x - µ)/σ

Where

x = incubation times.

µ = mean time

σ = standard deviation

From the information given,

µ = 23 days

σ = 1 day

The probability value for the incubation time that separates the bottom 2.5​% from the rest of the incubation times would be (1 - 2.5/100) = (1 - 0.025) = 0.975

Looking at the normal distribution table, the z score corresponding to the probability value is 1.96

Therefore,

1.96 = (x - 23)/1

x = 1.96 + 23

x = 24.96
