On a coordinate grid, point N is at (−2, 4) and point S is at (6, 4). The distance (in units) between points N and S is _______

KatRina [158]

You could use the distance formula or just reason this one out.
Both points are at y = 4 so they are on a horizontal line.
The distance from -2 to 6 is 8 units.
So the distance between N ans S is 8.

Bess and Gina earn $45 per week for delivering flowers. Bess worked for x weeks and earned an additional total bonus of $20. Gin

Inessa05 [86]

Answer:

First option: $45x + 20 + 45y$

Step-by-step explanation:

The missing options are:

$45x + 20 + 45y\\65x + 45y\\45x - 20 + 45y\\\\45x + 65y$

We know that "x" represents the number of weeks Bess worked and "y" the number of weeks Gina worked.

According to the data given in the exercise, Gina and Bess earn $45 per week for delivering flowers, this is:

$45x+45y$

Since earned an additional total bonus of $20, then the total money in in dollars that Bess and Gina earned for delivering flowers can be shown with the following expression:

$(45x+20)+45y=45x+20+45y$

Notice that this expression matches with the one shown in the first option.

The claim is that for the population of adult males, the mean platelet count is μ>217. The sample size is n=50 and the test

Deffense [45]

Step-by-step explanation:

First, find the degrees of freedom:

df = n − 1

df = 49

To find the p-value manually, use a t-score table. Find the row corresponding to 49 degrees of freedom. Then find the α column that corresponds to a t-score of 1.421. You'll find it's between α = 0.10 (t = 1.299) and α = 0.05 (t = 1.677). Interpolating, we get an approximate p-value of 0.084. For a more accurate answer, you'll need to use a calculator.
