A box of 20 jelly beans contains 6 red jelly beans. find the probability of randomly selecting a jelly bean from the box that is

Westkost [7]

If there are 6 red jelly beans in a box of 20 jelly beans, then you know that 14 are not red. So the probability of drawing a non-red jelly bean is 14/20, or 7/10.

Two sides of a triangle measure 6 cm and 8 cm. What is the possible measurement of the 3rd side of the triangle

Novosadov [1.4K]

Step-by-step explanation:

If the triangle is right, we can use Pitagora

We can have 2 results

$\sqrt{ {6}^{2} + {8}^{2} } = \\ = \sqrt{36 + 64} = \\ = \sqrt{100} \\ = 10$

$\sqrt{ {8}^{2} - {6}^{2} } = \\ = \sqrt{64 - 36} = \\ = \sqrt{28 } \\ = 2 \sqrt{7}$

Write an equation of a line that passes through the point (8,4) and is parallel to the y=4x+2

fomenos

Answer: $y=4x-28$

Step-by-step explanation:

The Slope-intercept form of the equation of the line is:

$y=mx+b$

m: is the slope.

b: the intersection of the line with the y-axis.

The equation of the line $y=4x+2$ has:

$m=4\\b=2$

If both lines are parallel, then their slopes are equal. So the slope of the other line is:

$m=4$

To find "b", substitute the given point and the slope into $]y=mx+b$ and solve for "b":

$4=4(8)+b\\4-32=b\\b=-28$

Then the equation of this line is:

$y=4x-28$
