Answer:

the probability of getting two heads is 1/4

Step-by-step explanation:

H = (HH) => n(H) = 1

n(S) = 4

P(E) = number of favourable outcomes/total number of outcomes = n(E) / n (S)

PH = n(H)/n(S)

= 1/4

Answer: $\frac{1}{4}$

Step-by-step explanation:

use probability

the chances of you getting heads on a coin is 50% therefore, flipping two coins is just

$\frac{1}{2} * \frac{1}{2}= \frac{1}{4}$

When you are solving an algebraic one-step equation, the goal is to isolate the variable on one side of the equal sign, two-step equations are the same, but with one more step (hence the name)

Write an equation in slope-intercept form for the line that is parallel to y=−4x−3 and that passes through the point (−2,4).

kirill115 [55]

Answer:

The Correct option is Last one $y=-4x-4$

Therefore, equation of the line in slope-intercept that passes through (-2,4) and is parallel to the line $y=-4x-3$ is $y=-4x-4$

Step-by-step explanation:

Given:

$y=-4x-3$

To Find:

Equation of line passing through ( -2, 4) and is parallel to the line y=-4x-3

Solution:

$y=-4x-3$ ..........Given

Comparing with Slope-Intercept form,

$y=mx+c$

Where m =slope

We get

$Slope = m = -4$

We know that parallel lines have Equal slopes.

Therefore the slope of the required line passing through (-2 , 4) will also have the slope = m = -4.

Now the equation of line in slope point form given by

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

Substituting the points and so we will get the required equation of the line,

$(y-4))=-4(x-(-2))=-4x-8\\\\y=-4x-8+4=-4x-4\\\\y=-4x-4......Equation\ of\ line$

Therefore, equation of the line in slope-intercept that passes through (-2,4) and is parallel to the line $y=-4x-3$ is $y=-4x-4$

Joe is 3 times as old as Pepe In how many years will Joe be only twice as old as Pepe ? How old are they now? How old will they

antoniya [11.8K]

Let x = Wally's age now

Then, 3x = Jose's age now

Wally's age 5 years from now = x+5

Jose's age 5 years from now = 3x+5

(x+5) + (3x+5) = 42

4x + 10 = 42

4x = 32 x = 8

Wally is 8 years old and Jose is 24.
