What is the distance between the points 4,10 and -3,-14 on the coordinate plane

Kryger [21]

Answer:

Step-by-step explanation:

Here we are supposed to find the distance between two coordinates ( 4,10) and (-3,-14).

Let us do this step by step with detailed explanation.

We will use distance formula in order to find the distance between them. The distance formula is given as

$D=\sqrt{(x_{2}-x_{1})^{2} +(y_{2}-y_{1})^{2} }$

Here we have

$x_{2}=-3\\x_{1}=4\\y_{2}=-14\\y_{1}=10\\$

Replacing them in the formula we get

$D=\sqrt{(-3-4)^{2} +(-14-10)^{2} }\\D=\sqrt{(-7)^{2} +(-24)^{2} }\\D=\sqrt{49+ 576 }\\D=\sqrt{625 }\\D=25\\$

Hence our distance is 25 units

What is the surface area of a coke bottle? how do you figure it out?

svetlana [45]

Can or bottle? A can will be the calculation for the surface area of a cylinder which is A= $2 \pi rh+2 \pi r^{2}$ if r is the radius of the circle on the top and bottom of the can and h is the height of the can. A can is basically two circles and a big rectangle. For a bottle I don't know there are too many components and no numbers to solve for that

In order to solve the equation −3x + 6 = 5, the first step is to (1 point)

aliya0001 [1]

−3x + 6 = 5 | -6 (first step is: "subtract 6 from both sides" )

-3x = 5-6
-3x = -1 | /(-3) (second step is: "divide by (-3) on both sides" )

 $\displaystyle \\ 
x = \frac{-1}{-3} = \boxed{\frac{1}{3} }$

A researcher is interested in determining the mean energy consumption of a new

Nana76 [90]

Answer:

The most appropriate value of the critical value is 2.289.

Step-by-step explanation:

We are given that a researcher takes a random sample of 41 bulbs and determines that the mean consumption is 1.3 watts per hour with a standard deviation of 0.7.

We have to find that when constructing a 97% confidence interval, which would be the most appropriate value of the critical value.

Firstly, as we know that the test statistics that would be used here is t-test statistics because we don't know about the population standard deviation.

So, for finding the critical value we will look for t table at (41 - 1 = 40) degrees of freedom at the level of significance will be $\frac{1 - 0.97}{2} = 0.015$ .

Now, as we can see that in the t table the critical values for P = 1.5% are not given, so we will interpolate between P = 2.5% and P = 1%, i.e;

$\frac{0.015 - 0.025}{0.025-0.01}= \frac{\text{Critcal value}-2.021}{2.021-2.423}$

So, the critical value at a 1.5% significance level is 2.289.
