alisha [4.7K]3 years ago
5 0

Answer:

Fraction of jokes of Brandon that are funny = \frac{3}{10}

Step-by-step explanation:

We are given that, 30% of the Brandon's jokes are funny.

Now, to convert percent into fraction, we will multiply it by \frac{1}{100}

Now,

30\%=30\times\frac{1}{100}=\frac{30}{100} = \frac{3}{10}

∴ \frac{3}{10} of the Brandon's jokes were funny.

find the value of x2 values that separate the middle 90% from the rest of the distribution for 8 degrees of freedom
Anettt [7]

Answer:

With alpha 0.95 and 8 degrees of freedom χ²= 2.73

And with alpha 0.05 and 8 degrees of freedom χ²=15.51

Step-by-step explanation:

The significance level ∝ = 1- 0.9 = 0.1

But we need the area of the middle so we divide this significance level with 2

so that we get exactly the middle area .

Dividing 0.1/2= 0.05

So we will have two values for chi square

One with  0.9 + 0.05 = 0.95 alpha and one with 0.05 alpha . This is because the chi square is right tailed.

So with alpha 0.95 and 8 degrees of freedom χ²= 2.73

And with alpha 0.05 and 8 degrees of freedom χ²=15.51

This can be shown with a graph.

Find the value of k so that the graph of 13y + kx = 4 and the line containing the points (5, -8) and (2, 4) are parallel.
guajiro [1.7K]

the graph of 13y + kx = 4 and the line containing the points (5, -8) and (2, 4) are parallel.

We find the slope of parallel line using two given points

(5, -8) and (2, 4)

Slope formula is

slope = \frac{y_2-y_1}{x_2-x_1}

slope = \frac{4-(-8)}{2-5}

slope = \frac{12)}{-3}=-4

so slope = -4

Slope of any two parallel lines are always equal

Lets find the slope of the equation 13y + kx = 4

Subtract kx on both sides

13 y = -kx + 4

Divide both sides by 13

y= \frac{-kx}{13} + \frac{4}{13}

Now slope = -k/13

We know slope of parallel lines are same

So the slope of 13y + kx = 4  is also -4

Hence we equation the slope and find out k

\frac{-k}{13}=-4

Multiply by 13 on both sides and divide by -1

k = 52

the value of k = 52

Find an equation of the vertical line through (-6,6). If possible, write a formula for a linear function whose graph is the give
Anvisha [2.4K]

Answer:

x = -6

Step-by-step explanation:

That's it. That's the vertical line through (-6, 6).

Literally just the x-coordinate (because it will be parallel to the y-axis, draw it out on a paper if confusion).
