Answer:

The x coordinate would be 4.

Step-by-step explanation:

In order to find this, we'll make the y terms cancel. To do this, we need to multiply the whole second term by -1 and then add them together.

3x + 5y = 10

-x - 5y = -2

-----------------

2x = 8

Now that we have this, we can divide to get the answer.

2x = 8

x = 4

Step-by-step explanation:

Is is a one-tailed test

P(z < 2.45) = 0.9929

1 - 0.9929 = 0.0071

Significant at both 0.05 and 0.01 because both are greater than 0.0071

Answer:

Step-by-step explanation:

It is true that for any given odd integer, square of that integer will also be odd.

i.e if $m$ is and odd integer then $m^{2}$ is also odd.

In the given proof the expansion for $(2k + 1)^{2}$ is incorrect.

By definition we know,

$(a+b)^{2} = a^{2} + b^{2} + 2ab$

∴ $(2k + 1)^{2} = (2k)^{2} + 1^{2} + 2(2k)(1)\\(2k + 1)^{2} = 4k^{2} + 1 + 4k$

Now, we know $4k^{2}$ and $4k$ will be even values

∴ $4k^{2} + 1 + 4k$ will be odd

hence $(2k + 1)^{2}$ will be odd, which means $m^{2}$ will be odd.

Answer:

736 Newtons

Step-by-step explanation:

Given

Pressure = $\frac{Force}{Area}$

Multiply both sides by Area

Area × Pressure = Force

Area = 2.3 × 1.6 = 3.68 m², hence

Force = 3.68 × 200 = 736 Newtons
