Simplify 2/4 please and thank you

klio [65]

Answer:

1/2

Step-by-step explanation:

2/4 is equal to 1/2, because if you divide 4 by 2 you get 2, and if you divide 2 by 2 you get one.

Basically, the simplification process would look something like this...

2/4 ÷ 2/2 = 1/2

Which equation represents a line that has a slope of Negative one-half and passes through point (4, –5)? y = negative one-half x

Anni [7]

Answer:

y = (-1/2)x - 3

Step-by-step explanation:

Please present the equation symbolically instead of in words:

m = -1/2, passing through (4, -5):

Using the slope-intercept formula y = mx + b, and using m = -1/2, x = 4 and y = -5, we get:

-5 = (-1/2)(4) + b, or -5 = -2 + b. Then b = -3 and the desired equation is:

y = (-1/2)x - 3

The probability that a newborn baby at the hospital is female is 50%. What is the probability that at least 2 babies of 3 childr

Readme [11.4K]

Answer:

0.25 is the probability

Step-by-step explanation:

In this question, we are tasked with calculating the probability that in a hospital on a certain day, at least 2 out of three babies born that day are female.

To calculate the probability , let’s list out some needed facts;

Let the probability of having a baby girl be g = 50% = 50/100 = 1/2 = 0.5

The probability of having a boy b will be 1-g = 1-0.5 = 0.5

Now, we have 3 babies and we want to find the probability of at lest two being girl.

Mathematically that would be ; ggb or ggg

since we are having at lest 2 girls

For the ggb, we have ; 0.5 * 0.5 * 0.5 = 0.125

For the ggg we have 0.5 * 0.5 * 0.5 = 0.125

In probability, once we have or, we add.

Thus 0.125 + 0.125 = 0.25

Is it ever possible that cos (A−B)=cos ⁡A−cos ⁡B? Why or why not?

Nookie1986 [14]

Answer:

The given equation is never possible i.e cos ( A - B ) ≠ cos A - cos B

Step-by-step explanation:

Given as :

Is cos ( A - B ) = cos A - cos B

To check this possibility , Let us put the value of angle A and B on both side of equation

Now, Let A = 60° and B = 30°

From Left hand side equation

cos ( A - B ) = cos ( 60° - 30° )

Or, cos ( A - B ) = cos 30°

∴ cos ( A - B ) = $\frac{\sqrt{3} }{2}$

or, cos ( A - B ) = 0.866

From Right hand side equation

cos A - cos B = cos 60° - cos 30°

Or, cos A - cos B = $\frac{1}{2}$ - $\frac{\sqrt{3} }{2}$

∴, cos A - cos B = 0.5 - 0.866

I.e cos A - cos B = - 0.366

So, Left hand side ≠ Right hand side

Since while equating the values of angle A and b in the given equation on both sides, we get that the value of both sides are not equal , Thus we can say that the given equation is not equal to each other .

Hence given equation is never possible i.e cos ( A - B ) ≠ cos A - cos B Answer

How many intersections are there of the graphs of the equations below? 1/2x + 5y = 6 3x + 30y = 36 none one two infinitely many

juin [17]

Solve both equations 1/2x + 5y = 6 becomes y = -1/10x + 5/6 and 3x +30y = 36 becomes y = -1/10x + 36/30. Since both equations have the same slope..1/10 the lines are going to be parallel since the constant is different 5/6 vice 36/30. They will never cross.
