Answer:

(4,5)

Step-by-step explanation:

The x coordinate moves from 3 to 5 which is +2

The y coordinate moves from 2 to 3 which is +1

We move the point (2,4)

(2+2, 4+1) becomes (4,5)

Answer:

P (X≤1) = 0.000

Step-by-step explanation:

Data given:

p = 79% = 0.79

q = 1 - 0.79 = 0.21

n = 16

P (no more than 1 in 16 adults) = P (X≤1)

P (X≤1) = P (X=0) + P (X=1)

We can find the probability by using binomial functions:

[tex]P=\frac{n!}{x!(n-x)!}p^x(1-p)^{n-x}[/tex]

P(X=0) = (16! / 0!(16-0)!) · 0.79⁰ · 0.21¹⁶

Use calculator to solve:

P(X=0) = 0.000000000798

P(X=1) = (16! / 1!(16-1)!) · 0.79¹ · 0.21¹⁵

Use calculator to solve:

P(X=1) = 0.000000034506

P (X≤1) = P (X=0) + P (X=1)

P (X≤1) = 0.000000000798 + 0.000000034506

P (X≤1) = 0.00000003530

P (X≤1) = 0.000

As 1 is a very low number, its probability is very small

Answer:

(3,2)

Step-by-step explanation:

The solution that satisfies both equations is where the two lines intersects.

The two graphs intersect at x=3 and y =2

Answer:

Divide the 7.5 by 3 to see how much bigger the ratio has to be.

7.5 / 3 = 2.5 so the ratio is 2.5 times bigger

multiply 5 by 2.5 to make the ratio equal and find the answer

5 x 2.5 = 12.5

It was 12.5 long and became 7.5 long

Answer:

48 degrees

Step-by-step explanation:

Angle 2 is a right angle.

Right angles are 90 degrees.

A line is 180 degrees.

Angle 1, 5, and 2 form a line.

180-90=90

That means that Angles 1 and 5 add up to 90 degrees.

We know that Angle 3 is 42 degrees.

Angle 3 and 5 are Vertical angles.

Vertical angles are always congruent.

This means that Angle 5 is also 42 degrees.

As we discussed earlier, Angles 1 and 5 are complementary. (Add up to 90 degrees)

42+x=90

Subtract 42 from both sides.

x=48

m<1=48

Answer:

It is 48 degrees because I took the test

Answer:

Experimental Probability is found:

P = 11/24

Step-by-step explanation:

Experimental Probability can be defined as the ration of the number of times (frequency) a desirable event has occurred, to the Total number of time (total frequency) the activity has been performed.

Probability = P = Frequency of an event / Total Frequency

To find the total frequency, we add all three of the given frequencies:

Total Frequency = 10 + 11 + 3

Total Frequency = 24

Frequency of the event (times bus arrived between 8:20 to 8:24) = 11

So, experimental probabilty is found as:

P = 11/24

Answer:

x = 3

y = 1

Step-by-step explanation:

9x - y = 26  ---------------(I)

9x + y = 28 ---------------(II)

9x - y = 26

9x = 26 + y

Substitute 9x = 26 + y in equation (II)

26 + y + y = 28               {add like terms}

26 + 2y = 28             {subtract 26 from both sides}

         2y = 28 - 26

        2y = 2    {divide both sides by 2}

           y = 2/2

y = 1

Substitute y =1 in equation (I)

9x - 1 = 26

9x = 26 + 1

9x = 27

x = 27/9

x = 3

x = 3

y = 1

The equation given is f(x) = x^2 - 12x + 27

Based on its form, it is a parabola. First, factor the quadratic equation:

f(x) = (x-9) (x-3)

Plot in the x-y plane, assign values of x and solve for the values of y.

Answer:

if he spent %10 more 400.110/100 he spent 440

he spent 40 more and his savings dropped %20 this means 40 is %20 of his total saving 40.5=200

Answer:

$200.

Step-by-step explanation:

Let his fixed monthly salary be x dollars.

Then he saved x-400 dollars in January.

He spent 10% more in February which is $440 so his savings were x-440 dollars, which is 0.20 less than in January. So we have the equation:

(x - 400)  - (x - 440) = 0.20(x - 400)

0.80(x - 400) =  x - 440

0.8x -  320 - x = -440

-0.20x = - 120

x = $600

So his saving in January were  600 - 400 = $200.

Answer:

[tex]9x+5y=-20[/tex]

Step-by-step explanation:

[tex]y = \frac{5}{9} x - 4[/tex]

compare with that y=mx+c

where m=slope .

So after comparing we get m=[tex]\frac{5}{9}[/tex]

As the lines are perpendicular

[tex]m1*m2=\ -1[/tex]

[tex]m2 \ =\ \frac{-1}{m1}[/tex]

therefore m2=[tex]\frac{-9}{5}[/tex]

Now from the equation

[tex]y - b = m(x - a )[/tex] this equation passing to the point (-5,5) with m=[tex]\frac{-9}{5}[/tex]

[tex]y-5=\frac{-9}{5} (x+5)\\5y-25=-9x\ -45\\9x+5y=-20[/tex]

Therefore equation is

[tex]9x+5y=-20[/tex]

Answer:

A. [tex] y= - \frac{1}{3} x[/tex]

Step-by-step explanation:

Line is passing through the point [tex] (3,\:-1)=(x_1, \:y_1) [/tex] and origin [tex] (0,\: 0)=(x_2, \: y_2) [/tex]

Equation of line in two point form is given as :

[tex] \frac {y-y_1}{y_1 - y_2} = \frac{x-x_1}{x_1 - x_2} \\\\

\therefore \frac{y-(-1)}{-1-0}= \frac{x-3}{3-0}\\\\

\therefore \frac{y+1}{-1}= \frac{x-3}{3} \\\\

\therefore 3(y+1) = - 1(x-3)\\\\

\therefore 3y + 3 = - x +3\\\\

\therefore 3y = - x +3-3\\\\

\therefore 3y = - x\\\\

Answer: 72

Step-by-step explanation:

Total Score of 90 nos

90 x 60 = 5400

Total score of 60 nos

60 x 90 = 5400

Average of (90 + 60) = 10800 / 150 = 72

Answer:

72

Step-by-step explanation:

You need to find the average of all the number.  However, you are given two averages that have unequal numbers.  To solve, you need to multiply each average by the amount of number it has in it.

90 × 60 = 5400

60 × 90 = 5400

You need to find the total amount of number as well as the total value of the numbers.

90 + 60 = 150

5400 + 5400 = 10800

Divide the total value by the total amount of number to find the average.

10800/150 = 72

The total average is 72.

Answer:

-11

Step-by-step explanation:

There is enough information to put the equation in point slope form.

[tex]y-y_1=m(x-x_1)[/tex]

We are given the point of (-5,4) and the slope of -3.

[tex]y-y_1=m(x-x_1)\rightarrow \boxed{y-4=-3(x+5)}[/tex]

Now, we can take the point slope equation and convert it into slope intercept form.

[tex]y-4=-3(x+5)\\\\\left \{ {{-3*x=-3x} \atop {-3*5=-15}} \right.\\\\ y-4=-3x-15\\\\y-4+4=-3x-15+4\\\\\boxed{y=-3x-11}[/tex]

The y-intercept should be -11.
