When you're given a parallel line, that means you know that both lines should have the same slope m.
And you're given a point (x,y) so you plug in the x for $x_{1}$ in the equation and y for $y_{1}$ in the equation.
Also plug in m because that was given.

y - $y_{1}$ = m(x - $x_{1}$ )

Then you can simplify the equation to get y = mx + b

We need to get the parallel line<span> into slope-intercept form</span> is y=mx+n
and the POINT(A,B)
and we write the new equation y-B=m(x-A)+n

Dr. Bayer measured the masses of newborn twins. Baby A weighs 2.8 kilograms. Baby B weighs 2,950 grams. What is the difference b

nikklg [1K]

Convert 2.8 kilograms into 2800 grams.

Baby A weighs 2800 grams, baby B weighs 2950 grams -> The difference between the masses = 2950 - 2800 = 150 grams.

Just before a referendum on a school budget, a local newspaper polls 402 voters to predict whether the budget will pass. Suppos

Sliva [168]

Answer:

21.21%

Step-by-step explanation:

Assume that proportion of support follows normal distribution.For resulting in defeat the proportion of support should less than 0.5.Given that the proportion of support is p= 0.52.

Sample size(n)= 402

We know that standard deviation is given as

$\sigma = \sqrt {\dfrac {p(1-p)}{n}}$

Now by putting the values

$\sigma = \sqrt {\dfrac{0.52\times 0.48}{402}}$

σ=0.0249

Proportion of support follows normal distribution with mean is 0.52 and standard deviation is 0.0249

We know that $Z=\dfrac{\bar{X}-\mu }{\sigma }$

$Z=\dfrac{0.5-0.52 }{0.0249}$

Z= -0.80

So P(Z<-.80) =0.2118 from standard table.

So the probability of news paper to predict defeat is 21.21%

Given the figure below, find the values of x and z.

aleksandrvk [35]

Answer: x = 2 and z=78

Step-by-step explanation:

Opposite angles are non-adjacent angles formed by two intersecting lines. Opposite angles are congruent (equal in measure). Z is Opposite to 78 angle, so z=78.

Adjacent angles add up to 180 degrees, and 78 and (5x + 92) are adyacents so:

5x + 92 + 78 = 180

5x + 170 = 180

5x = 180 - 170

5x = 10

x = 10/5

x = 2
