Answer:

B, C, and F.

Step-by-step explanation:

since there is a negative x-coordinate, it has to be on the left side of the coordinate plane. There are only 2 Quadrants on that side, Quadrant II, and quadrant III. It also said that the y-coordinate is not 0, so It cannot be on the x-axis becuase that would mean that the y-coordinate is 0, but it said nothing about the x-coordinate not being 0.

Researchers measured the data speeds for a particular smartphone carrier at 50 airports. The highest speed measured was 76.676.6
faltersainse [42]

Answer:

Step-by-step explanation:

Researchers measured the data speeds for a particular smartphone carrier at 50 airports.

The highest speed measured was 76.6 Mbps.

n= 50

X[bar]= 17.95

S= 23.39

a. What is the difference between​ the carrier's highest data speed and the mean of all 50 data​ speeds?

If the highest speed is 76.6 and the sample mean is 17.95, the difference is 76.6-17.95= 58.65 Mbps

b. How many standard deviations is that​ [the difference found in part​ (a)]?

To know how many standard deviations is the max value apart from the sample mean, you have to divide the difference between those two values by the standard deviation

Dif/S= 58.65/23.39= 2.507 ≅ 2.51 Standard deviations

c. Convert the​ carrier's highest data speed to a z score.

The value is X= 76.6

Using the formula Z= (X - μ)/ δ= (76.6 - 17.95)/ 23.39= 2.51

d. If we consider data speeds that convert to z scores between minus−2 and 2 to be neither significantly low nor significantly​ high, is the​ carrier's highest data speed​ significant?

The Z value corresponding to the highest data speed is 2.51, considerin that is greater than 2 you can assume that it is significant.

I hope it helps!

A catapult is malfunctioning and not throwing objects in the intended manner. The builders have modeled the path of the objects
Elenna [48]

Answer:

The equation is y ^ 2 = \frac{x + 1}{2}

Step-by-step explanation:

The parameter that we have is t. We want to eliminate this parameter in both equations, therefore in the first equation we solve for t and in the second equation we solve for the variable t.

We have:

x = 2t-1\\\\x + 1 = 2t\\\\t = \frac{x + 1}{2}

Now we solve the other equation for t.

y= \sqrt{t}

y ^ 2 = t    <em> because</em>   t> 0

As t = y ^ 2 and also t = \frac{x + 1}{2}

Then:

y ^ 2 = \frac{x + 1}{2}
