Write an equation of the line that is perpendicular to y = 1/2

atroni [7]

Answer:

the equation of the line that is perpendicular to y = 1/2x + 3 and passes through the point (10, -5)

= -5 = -2x + 15

Step-by-step explanation:

Write an equation of the line that is perpendicular to y = 1/2x + 3 and passes through the point (10, -5).

Using the slope intercept equation,

y = mx +c

m = slope = 1/2

For two lines to be perpendicular, the product of their slopes is -1

Let the slope of the other line be m2

m1×m2 =-1

1/2×m2 = -1

m2 = -1/(1/2) = -2

Slope of line = -2

For points (10, -5), x = 10, y =-5

-5 = -2× 10 +c

-5 = -20+ c

c = -5+20= 15

the equation of the line that is perpendicular to y = 1/2x + 3 and passes through the point (10, -5)

-5 = -2x + 15

Answer:

$P(X=7)$

And using the probability mass function we got:

$P(X=7)=(15C7)(0.23)^7 (1-0.23)^{15-7}=0.0271$

Step-by-step explanation:

Let X the random variable of interest, on this case we now that:

$X \sim Binom(n=15, p=0.23)$

The probability mass function for the Binomial distribution is given as:

$P(X)=(nCx)(p)^x (1-p)^{n-x}$

Where (nCx) means combinatory and it's given by this formula:

$nCx=\frac{n!}{(n-x)! x!}$

And we want to find the following probability:

$P(X=7)$

And using the probability mass function we got:

$P(X=7)=(15C7)(0.23)^7 (1-0.23)^{15-7}=0.0271$

1. Ratio between onions and tomatoes:

There are 3 onions and 4 carrots.

Therefore, required ratio is 3:4

2. Ratio between tomatoes to cups of chicken stock:

There are 6 tomatoes and 5 cups of chicken stock.

Hence, the required ratio is 6:5.

3. Sticks of butter to bananas:

There are 1 stick of butter and 2 bananas.

So, the required ratio is 1 to 2.

4. Teaspoons of salt to teaspoons of black pepper:

There are 2 teaspoons of salt and 1 teaspoon of black pepper.

Please refer attached figure.

5. Let's calculate the ratio of cups of chocolate chips to tomatoes.

There are 3 cups of chocolate chips and 6 tomatoes.

Hence, the required ratio is 3:6 and on simplifying, 1:2.
