Find the equation of the line which passes through the point (1,2), and is perpendicular to the line with the equation y=−12x+5.

malfutka [58]

12y = x + 23

Step-by-step explanation:

y = −12x + 5
Perpendicular slopes are opposite reciprocals.
The original slope is −12
So the new perpendicular slope is 1/12.
We plug the point (1, 2) and the slope m = 1/12 into the slope intercept form of the equation y = mx + b

y = mx + b

2 = 1/12 * 1 + b

2 = 1/12 + b

b = 23/12

When we simplify this, we arrive at 12y = x + 23

:( A=? B=? please help me

Helen [10]

a= 16x+16

b= 40x + 15

Step-by-step explanation:

We know that perimeter of a rectangle is

$2(l + b)$

So therefore

$2(8x + 3 + 5) = a$

$= > 16x+ 6 + 10 = a$

$= > 16x + 16 = a$

Answer= A) that is perimeter is 16x+16

We know that area of a rectangle is l×b

So therefore

$(8x + 3) \times 5$

$= 40x + 15$

Answer = b) that is area is 40x + 15

The probability is 51% that the sample mean will be between what two values, symmetrically distributed around the population

Alisiya [41]

Answer:

The lower bound is, $-z=-0.69$ and the upper bound is $z=0.69$ .

Step-by-step explanation:

Let the random variable X follows a normal distribution with mean μ and standard deviation σ.

The the random variable Z, defined as $Z=\frac{X-\mu}{\sigma}$ is standardized random variable also known as a standard normal random variable. The random variable $Z\sim N(0, 1)$ .

The standard normal random variable has a symmetric distribution.

It is provided that $P(-z\leq Z\leq z)=0.51$ .

Determine the upper and lower bound as follows:

$P(-z\leq Z\leq z)=0.51\\P(Z\leq z)-P(Z\leq -z)=0.51\\P(Z\leq z)-[1-P(Z\leq z)]=0.51\\2P(Z\leq z)-1=0.51\\2P(Z\leq z)=1.51\\P(Z\leq z)=0.755$

Use a standard normal table to determine the value of z.

The value of z such that P (Z ≤ z) = 0.755 is 0.69.

The lower bound is, $-z=-0.69$ and the upper bound is $z=0.69$ .
