PLEASE ANSWER THIS
FOR POINTS

Answer:

Step-by-step explanation:

there is a formula for finding distance,

distance = sqrt [ ( x2-x1)^2 + (y2-y1)^2 ]

where point P1 = (-9.-6)  

    in the form of (x1,y1)

and point P2 = (-2,-2)  

 in the form of (x2,y2)

then

distance = sqrt [ (-2-(-9))^2 + (-2-(-6))^2 ]

distance = sqrt [ (-2+9)^2 + (-2+6)^2 ]

distance = sqrt [  [tex]7^{2}[/tex] + [tex]4^{2}[/tex] ]

distance = [tex]\sqrt{65}[/tex]

you can leave it in the form of  [tex]\sqrt{65}[/tex] because that's the most accurate , but also can make a close approximation with  8.062257748

That's all the places my calculators goes out to, the numbers continue thou.

Answer:

Step-by-step explanation:

Find the area of the garden:

Number of plants:

Answer:

Solution given:

perpendicular [P]=15m

base[B]=8m

hypotenuse [H]=17m

rate :4 plants per square metre

no of plants=?

we have

Area of triangular garden: ½(P*B)=½(15*8)=60m²

Now

Total no of plants =rate ×Area =4×60=240

Michael needs 240 plants in the garden.

ATQ,

= [tex] \dfrac{ - 13}{25} + \dfrac{21}{5} + \frac{ - 21}{18} + x = 5[/tex]

= [tex] \dfrac{ 377}{150} + x = 5[/tex]

= [tex] x = 5 - \dfrac{ 377}{150}[/tex]

= [tex] x = \dfrac{ 373}{150}[/tex]

Answer

=727/150

Step-by-step explanation:

-13/25 + 21/18 + 21/18

= -13 + 105/25 + 21/18

= 92/25 + 21/18

= 1656 + 525/450

= 2181/450   =   727/150

Answer:

x=1/4

Step-by-step explanation:

1/4+3/4=1 whole

Answer:

[tex]x = \frac{1}{4}[/tex]

Step-by-step explanation:

Step 1: Subtract [tex]\frac{3}{4}[/tex] from 1

[tex]1 - \frac{3}{4}\\\\= \frac{1}{4}[/tex]

Therefore, the point could be [tex]\frac{1}{4}[/tex]

Answer:

2+4+5 = 11. since there are 5 green marbles the answer is 5/11

Answer:

-11

Step-by-step explanation:

let f(c) = 4c - 3

f(-2) = 4(-2) - 3 = -8 -3 = -11

Answer:

-11

Step-by-step explanation:

4c - 3

c = -2

4(-2) - 3

-8 - 3

-11

4c - 3 = -11 when c = -2

8+z/3=12

8+4=12

12/3=4

z=12

Answer:

6.3

Step-by-step explanation:

Answer:

The 95% confidence interval for the mass of a microchip produced at this factory is between 1971.608 milligrams and 1972.392 milligrams.

Step-by-step explanation:

We have that to find our [tex]\alpha[/tex] level, that is the subtraction of 1 by the confidence interval divided by 2. So:

[tex]\alpha = \frac{1 - 0.95}{2} = 0.025[/tex]

Now, we have to find z in the Z-table as such z has a p-value of [tex]1 - \alpha[/tex].

That is z with a pvalue of [tex]1 - 0.025 = 0.975[/tex], so Z = 1.96.

Now, find the margin of error M as such

[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]

In which [tex]\sigma[/tex] is the standard deviation of the population and n is the size of the sample.

[tex]M = 1.96\frac{2}{\sqrt{100}} = 0.392[/tex]

The lower end of the interval is the sample mean subtracted by M. So it is 1972 - 0.392 = 1971.608 milligrams

The upper end of the interval is the sample mean added to M. So it is 1972 + 0.392 = 1972.392 milligrams

The 95% confidence interval for the mass of a microchip produced at this factory is between 1971.608 milligrams and 1972.392 milligrams.

Answer:

-6

Step-by-step explanation:

Substitute the value of the variable into the equation and simplify.

Answer:

-6 (not 100% sure)

Step-by-step explanation:

4x = 28

4 × 7 = 28

so

29 - 5x

if x is 7, 5 × 7 = 35

29 - 35 = -6

Answer:

  the correct choice is marked

Step-by-step explanation:

The line has a rise of 2 for a run of 1, so a slope of 2. The line crosses the y-axis at y=-2, so the y-intercept is -2. The slope-intercept equation for the line is ...

  y = mx + b . . . . . . for slope m and y-intercept b

  y = 2x -2

Answer:

Option A, Measure of data centrality

Step-by-step explanation:

Normal distribution curve determines the skewness of the data as to what extent is is disoriented from the normal distribution curve. Also, it is the probability distribution curve that determines whether the data set is two legged, one legged or it lies under which probability curve.

Hence option A is correct

Step-by-step explanation:

you would do 25 / 25 and 176 / 25 and you would get 1 petrol and 7.04 miles

then 1 times 44 and 7.04 times 44 and that would be 44 petrol and 309.76 miles

Uh oh, looks like you need the graph to answer this question! If you post the graph then I can answer in numbers but for now, I'll try to explain:

1) I assume the graph looks like a dome shape, so based on that, where the line comes back down and hits the bottom line on which x value is larger will be whose stone hit the water second and what time will be what x value represents the time it hit the water.

2) look at the highest value on the purple graph and that is the maximum height (the y value of that point) and the x value of that highest point will be the time it took for the stone to reach its maximum height.

3) based on this question, the graph should start not on the 0 but at a point on the y axis, so whoever's starting y value is higher will be this answer and what that is will be the number answer to the what was it part.

Hope this helps and if you post the graph then I can do more! :)
