Equation of a straight line

y = mx + c, m is the slope, and c the intercept

points (3,7) x = 3, y = 7, c = 1

7 = m × 3 + 1

7 = 3m + 1

3m = 7 - 1

3m = 6

m = 6/3

m = 2

Step-by-step explanation:

-3x + 3y = 27

-x + y = 9

y = x + 9

so the y-intercept is 9 (y value when x =0).

and as point (0, 9)

the x-intercept is the x value when y = 0 :

0 = x + 9

x = -9

and as point (-9, 0)

Answer:

x = 21

Upper angle has a measure of 69°

Lower angle has a measure of 21°

Step-by-step explanation:

The two angles form a right angle ( indicated by the little square )

A right angle has a measure of 90 degrees.

This means that (x + 48) + x must equal 90

Note that we've just created an equation that we can use to solve for x

We now solve for x using that equation

x + 48 + x = 90

combine like terms

2x + 48 = 90

subtract 48 from both sides

2x = 42

divide both sides by 2

x = 21

We then plug in x to find the measures of the angles

x + 48

x = 21

21 + 48

= 69

The other angle simply equals 21°

Answer:

x = 21°

(x + 48°) = 69=

Step-by-step explanation:

x + 48° + x = 90°

2x +48° = 90° Subtract 48° in both sides

2x = 42° Divide both sides by 2:

x = 21°

Hello! I hope you are having a nice day. My name is Galaxy and I will be helping you today.

We can solve this problem in a single step, we just need to know how equations like this are set up.

Equations in slope intercept form are set up in [tex]y=mx+b[/tex] form. With [tex]m[/tex] being the slope of the line, and [tex]b[/tex] being the y intercept.

In your problem, we need to find the value of [tex]b[/tex], which is the y intercept.

The y intercept is what is y when x is zero. We can find that by looking at the graph supplied.

When we look at the line, we can see that it hits the x axis when y is negative two, therefore the intercept is [tex](0,-2)[/tex].

Since we know that, we can reconstruct our equation with this information, we already know the slope so we can add in -2 to get our answer.

[tex]y=3x-2[/tex]

This would be our final answer.

Cheers!

Find the diagram attached.

Given the parameter:

m<2 = 98 degrees

From the diagram, the following are true:

m<2 = m<3 = 98 degrees (vertical angles)

The sum of m<3 and m<4 is 180 degrees.

m<3 + m<4 = 180

m<4 = 180 - m<3

m<4 = 180 = 98

Answer:

Maria, because 3/4=.75    

Step-by-step explanation:

3/4=.75

3/8=0.375

The bigger number is 3/4

Explanation:

The f(x) function is piecewise, and it has a double identity depending on what x is.

If x is between -6 and 1, excluding -6 but including 1, then f(x) = -6. This is the same as saying y = -6. This produces a horizontal flat line from x = -6 to x = 1. Note the open hole at x = -6 to indicate it's not part of the graph. In contrast, the closed hole at x = 1 is included.

The second piece says that y = -2x+5 when x is between 1 and 6, excluding both endpoints. We have open holes at each endpoint.

So to summarize, the f(x) function is a collection of two different functions depending on what the x input is. We only draw a small piece of each function based on the intervals provided by x.

Using the hypergeometric distribution, it is found that there is a 0.0002 = 0.02% probability that 4 of those containers are the same flavor.

The flavors are chosen without replacement, which means that the hypergeometric distribution is used to solve this question.

Hypergeometric distribution:

[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}C_{N-k,n-x}}{C_{N,n}}[/tex]

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

The parameters are:

In this problem:

The probability of choosing all containers of one flavors is P(X = 4).

[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}C_{N-k,n-x}}{C_{N,n}}[/tex]

[tex]P(X = 4) = h(4,52,5,4) = \frac{C_{4,4}C_{48,1}}{C_{52,5}} = 0.000018469[/tex]

13 x 0.000018469 = 0.0002

0.0002 = 0.02% probability that 4 of those containers are the same flavor.

A similar problem is given at https://brainly.com/question/25743676

The probability that 4 of those containers are the same flavor is 0.02% and this can be determined by using the Hypergeometric distribution.

Given :

The probability according to the Hypergeometric distribution is given by:

[tex]\rm P(X=x) = h(x,N,n,k)=\dfrac{C_{k,x}C_{N-k,n-x}}{C_{N,n}}[/tex]     --- (1)

where the total number of successes is 'x', population size is 'N', the sample size is 'n', and the total number of desired outcomes is 'k'.

Now, substitute the values of known terms in the expression (1).

[tex]\rm P(X=4) = h(4,52,5,4)=\dfrac{C_{4,4}C_{48,1}}{C_{52,5}}[/tex]

[tex]\rm P(X=4) =0.000018469[/tex]

Now, multiply the above result by 13.

[tex]13\times 0.000018469=0.0002[/tex]

So, the probability that 4 of those containers are the same flavor is 0.02%.
