Tell whether (1,0) is a solution of y=3x-3

Answer: x = 3.25, y = -1.5

Step-by-step explanation:

y = -2x + 5

4x - 2(-2x + 5) = 16

4x + 4x - 10 = 16

8x = 26

x = 3.25

2(3.25) + y = 5

y = -1.5

Answer:

In the equation y=mx+b, 'm' is the slope of the line and 'b' is the y-intercept.  

First, you should find the slope of the line.  To do this, use the equation M=y2-y1/x2-x1.  Using the two given points (3,6) and (8,4), you can solve for M.  

M=4-6/8-3

M=-2/5 (-0.4 in decimal form)

Now, your equation is y=-0.4x+b

Next you must solve for b to find the y-intercept.  You can do this by subbing one of the given points in for x and y.  

Using the point (3,6):

y=-0.4x+b

6=-0.4(3)+b

6=-1.2+b

Isolate b:

6+1.2=b

b=7.2

And now you have the equation of the line!

y=-0.4x+7.2 (IN FRACTION FORM: y=-2/5x+36/5)

Step-by-step explanation:

Answer:

a) Yes

Step-by-step explanation:

Because, 3+7=10

Answer: yes

Explanation: In this problem, to determine whether c = 3

is a solution to the equation, we substitute 3 in for c.

So we have (3) + 7 = 10.

Simplifying the left side of the equation, (3) + 7 is 10.

So we have 10 = 10 which is a true statement so our answer is yes.

Answer:

[tex]H_{0} = 0.5[/tex]

[tex]H_{a} > 0.5[/tex]

Option b

Step-by-step explanation:

Researchers conducted a study to determine whether the majority of community college students plan to vote in the next presidential election.

The null hypothesis is always an equalityu related to the expected, or tested value. In this question, the tested value is half of the students, a proportion of 0.5, that is: [tex]H_{0} = 0.5[/tex]

The alternate hypothesis is related to the test we are taking. In this question, we are testing if the majority of the students plan to vote, that is, if the proportion of the students that plan to vote is higher than 0.5. So [tex]H_{a} > 0.5[/tex]

So the correct answer is given by option B.

Answer: The slope = 5.

Step-by-step explanation:

The equation of a line in the slope -intercept form is given by :-

[tex]y=mx+c[/tex]

,where  m= slope , c= y-intercept.

The slope of a line represents the rate of change of y with respect to x.

Given: Equation of line : Y= 5x+12

Here Slope (m)=5

Hence, the slope = 5.

Answer:

274

Step-by-step explanation:

Hey There!

So if you didnt know the median is the middle number ( in value) of the set

So first we would like to arrange the numbers in order from least to greatest

187 , 199 , 211 , 250 , 298 , 331 , 347 , 362

Then we take the middle number(s)

if there is just one then that is the answer but if there is two than we add them together and divide that by 2

In this case there are two which would be 250 and 298

So we add them together

250+298=548

Then we just divide that by 2

[tex]\frac{548}{2} =274[/tex]

Therefore the median is 274

hope this helps :)

Answer:

Sorry I don’t know

Step-by-step explanation:

a3=25

a8=-10

first, a3=25 will be 25= a + (3-1)×d that is the formula of the Arithimetic function genrally→ an=a (which is the first term..that we wanted in this case) + n-1 (n is the order of wanted term..we already has the term which is 3) × d (the common ration).

So, 25=a+(3-1)×d

25=a+2d

25-2d=a   rearrange

a= 25-2d

We will take this equation and subsitute it in the other equation which is -10=a+ (8-1)×d

so it will be -10=25-2d+(8-1)×d

-10= 25-2d+7d   sum the d

-10= 25+5d

-10-25= 5d

-35=5d

-35/5=d

-7= d

Now that we have the d we can go back to the equation of a= 25-2d and know the value of a

a= 25-2×-7

a1=39

d=-7

The piece of glass's area is is 64 square cm.

Diagonals of a Square A square has two diagonals, they are equal in length and intersect in the middle.

The length of square is given by;

Each side of a square piece of glass is 8 centimeters long.

The piece of glass's area is;

[tex]\rm Glass \ area=a^2\\\\ Glass \ area=8^2\\\\ Glass \ area=64[/tex]

Answer:

Factor.

Step-by-step explanation:

In Mathematics, the quadratic formula is used for determining the two factors (roots) of any quadratic equation.

The standard form of a quadratic equation is ax² + bx + c = 0

Mathematically, the quadratic equation is given by the formula;

[tex] x = \frac {-b \; \pm \sqrt {b^{2} - 4ac}}{2a} [/tex]

Answer:

kelly would of hit the ball 90 times in 150 seconds

Step-by-step explanation:

you take 30 and divide it by 50 and you get 0.6.

then you take 0.6 and times it be 150

Answer:

90 times

Step-by-step explanation:

The equation set-up for if she bounces a basketball 30 times in 50 seconds is 30x=50. This means that she bounced the ball every 1 2/3 second. According to this, our next equation set-up would be 1 2/3x=150. If we divide 150 by 1 2/3, we get 90. This means that Kelly bounced the basketball 90 times in 150 seconds.

Complete question :

The expected value of a random variable X is 140 and the standard deviation is 14. The standard deviation of the random variable Y=3X-10 is:

Answer:

42

Step-by-step explanation:

Standard deviation of Y = 3X - 10

The variance of Y

Var(Y) = Var(3X - 10)

Var(Y) = Var(3X) - Var(10)

10 is a constant :

Var(10) = 0

Hence,

Var(Y) = Var(3x)

SD(Y) = Var(Y) = Var(3X)

SD(Y) = SD(3X)

SD(Y) = 3SD(X)

SD(X) = 14

SD(Y) = 3 * 14

SD(Y) = 42

The length of the ladder is [tex]x = \sqrt{100} =10 feet[/tex].

To find out the length of the ladder leaning against the building given the following conditions; bottom of the ladder is 6 feet from the building, and the top of the ladder reaches the wall at a height of 8 feet, the Pythagorean theorem can be utilized.

Therefore the length of the ladder is approximately 10 feet.

The Pythagorean theorem states that for a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.

This can be expressed as:

[tex]c^2=a^2+b^2[/tex]

where c is the hypotenuse (the longest side of the triangle)

a and b are the other two sides

Given, the distance from the bottom of the ladder to the wall is 6 feet and the height from the ground to the top of the ladder is 8 feet.

Let the length of the ladder be x

According to the Pythagorean theorem:

[tex]x^2 = 6^2 + 8^2 x^2[/tex]

[tex]x^2 = 36 + 64x^2[/tex]

[tex]x^2 = 100[/tex]

Therefore the length of the ladder is [tex]x = \sqrt{100}= 10 feet[/tex].

Answer:

a very weak relationship between cost and volume

Step-by-step explanation:

The R factor is used to access the strength of the relationship between a dependent and independent variable. The R factor ranges between - 1 and 1. With negative values depicting a negative linear relationship and positive values meaning a positive relationship. The closer the R factor is to - 1 or + 1, the greater the strength, a value of 0 means, no correlation exists.

Hence, a R factor of 0.15 depicts a positive but very weak relationship between cost and volume as the R value is close to 0.
