Answer:

The answer to your question is slope = -4, y-intercept = 6

Step-by-step explanation:

Data

Equation          y = -4x + 6

slope = ?

y-intercept = ?

Process

If we have the equation of a line in the slope y-intercept is very easy to find the values.

The slope is the coefficient of the x.

The y-intercept is the independent term ( the number after the x).

From the equation given, the slope = -4

                                           the y-intercept = 6

lara [203]

Answer:

-9\frac{1}{2}

Step-by-step explanation:

2x+1=0

2x=-1

x=-\frac{1}{2}

x+8=0

x=-8

2x-4=0

2x=4

x=2

x-1=0

x=1

1+2-8-\frac{1}{2}

=-1-8\frac{1}{2}

=-9\frac{1}{2}

Sum of fractions =-9\frac{1}{2}

In China, where many couples were allowed to have only one child, the probability of a baby being a boy was 0.545. Among six ran
wariber [46]

Answer: 0.9738

Step-by-step explanation:

This is solved by the probability distribution formula for random variables where probability of determining random variable X is given by

P(X=r) = nCr * p^r * q^n-r

Where n = number of sample = 6

p = probability of success = 0.545

q = 1-p = 0.455

r = possible outcome from number of sample.

If 6 random births are chosen, Probability that at least 1 of them is a girl = 1 -[probability that none of them is a girl] = 1 - [probability that all 6 kids are boys]

Probability that all 6 kids are boys = 6C6 * 0.545^6 * 0.455^0 = 0.0262

Probability that at least one is a girl = 1 - 0.0262 = 0.9738.

find the volume of the following figure round your answer to the nearest tenth if necessary and make sure to use pi
Vikki [24]

Answer:

524cm^2

Step-by-step explanation:

Formula for Volume of sphere= 4/3 πr^2

We have,

r=5cm

Now,

Volume(v)=4/3 πr^2 = 4/3π 5^3= 4/3π 125 = 166.666666667π = 523.598775599

Rounding to the nearest tenth,

Volume=524cm^2

Anyone know how to do area or volume? Any help will do! thanks
exis [7]

Answer:

Volume: x(x+6)(x+2) Area: x^{2} + 8x +12

Step-by-step explanation:

Volume Explanation:

To find the volume of a 3d figure, we must multiply the length, width, and the height. Therefore we multiply (x)(x+6)(x+2)= x^{3} + 8x^{2} + 12x. Simplify this equation and we will get x(x+6)(x+2) for the formula to find the volume of the 3D figure.

Area:

To find the area of a 2D figure, we must multiply length x height. Therefore, we multiply the equations (x+6)(x+2)= x^{2} + 2x + 6x +12 to get a final answer of x^{2} +8x +12.  This will be the formula when you find the area of the 2D figure in question.
