X=3y+10 x=-8y-12<br><br> can u guys help me find the steps to solve this equations

Natalija [7]

Answer:

x=4, y=-2

Step-by-step explanation:

$x = 3y + 10 \\ x = - 8y -12\\ now \\ 3y + 10 = - 8y - 12 \\ 3y + 8y = - 12 - 10 \\ 11y = - 22 \\ y = \frac{ - 22}{11} \\ y = - 2 \\ again \: putting \: the \: value \:of \: y \\ x = 3y + 10 \\ x = 3( - 2) + 10 \\ x = - 6 + 10 \\ x = 4$

Suppose a normal distribution has a mean of 62 and a standard deviation of4. What is the probability that a data value is betwee

saw5 [17]

SOLUTION

From the given data the mean is 62 and standard deviation is 4

It is required to find the probability that a data value is between 57 and 62

That is:

$P(57\lt x\lt65)$

The z scores is calculated using:

$z=\frac{x-\mu}{\sigma}$

Using the x values it follows:

$z=\frac{57-62}{4}=-1.25$

Also,

$z=\frac{65-62}{4}=0.75$

Thus the required probability is:

$P(-1.25The proability is:[tex]P(-1.25This can be expressed as percentage as:[tex]P(-1.25\lt z\lt0.75)=66.8\%$

Therefore the correct option is C

Answer:

Average velocity is 32 miles/hr.

Step-by-step explanation:

Given that a particle moves on a line away from its initial position so that after t hours it is $s=6t^2+2t$ miles from its initial position.

We have to find the average velocity of the particle over the interval [1, 4].

As, average velocity is the change is position over the change in time.

$s(4)=6(4)^2+2(4)=104$

$s(1)=6(1)^2+2(1)=8$

∴ $\text{Average Velocity=}\frac{s(4)-s(1)}{4-1}$

= $\frac{104-8}{3}=\frac{96}{3}=32miles/hr$

Hence, average velocity is 32 miles/hr.
