Archaeologists want to represent a rectangular dig site on the coordinate grid. Each unit represents 1 m. Three vertices of the

rectangle are A(‚àí6,7) , B(4,7) , and C(4,‚àí4) . Use the point tool to plot these three points, and then plot the fourth vertex of the rectangle. Label the points A, B, C, and D. Then use the segment tool to draw all 4 sides of the rectangle. The archaeologists found artifacts at two locations within the dig site. The point for location 1 is shown on the grid and labeled 1.The coordinates for location 2 are (‚àí2,4) . Plot a point to represent location 2, and then label that point 2.

What is the equation of a line that passes through (4, 3) and has a slope of 2?
KiRa [710]
So right of the bat the equation we know from what's given is y = 2x (+b)
we gotta find out what b is
so we plug the coordinate in
3=8+b.
b=-5
so we put all the pieces back together to get
y = 2x - 5

You apply for a job and have to take a drug test. You are curious about the error rate for the test so you do some research. You
Ber [7]

Answer:

Test statistic  Z = -1.0

 |Z| = |-1.0| < 1.96 at 0.05 level of significance.

The null hypothesis is accepted

The company that produces the drug test claims that less than 14% of the test results are wrong

Step-by-step explanation:

<u><em>Step(i):-</em></u>

Given that the population proportion P = 14% =0.14

Given that the sample size 'n' = 382 tests

Given that find a study where 47 out of 382 test results using this test were wrong (either a false positive or a false negative).

Sample proportion

                        p = \frac{x}{n} = \frac{47}{382} = 0.1230

Null hypothesis: H₀ : P = 0.14

Alternative Hypothesis:H₁ : P≠ 0.14

<u><em>Step(ii):-</em></u>

Test statistic

              Z = \frac{p-P}{\sqrt{\frac{PQ}{n} } }

         Z = \frac{0.1230-0.14}{\sqrt{\frac{0.14 X0.86}{382} } }

       Z = - 1.0

     |Z| = |-1.0| < 1.96 at 0.05 level of significance.

<u><em>Final answer:-</em></u>

The null hypothesis is accepted

The company that produces the drug test claims that less than 14% of the test results are wrong

A number y is rounded to 2 decimal places
Yakvenalex [24]
Y can be rounded up to 1.51 from a minimum value of 1.505
This is the lower bound.

y can be rounded down to 1.51 from a maximum value of 1.515
this is the upper bound.

y is between the lower bound and the upper bound so y is between 1.505 and 1.515

This is shown as 1.595<=y<1.515

<= is the typed out version of (greater than/equal to) which is < with a line under it.

Which side of angle measures could be the interior angles of a triangle?
jok3333 [9.3K]

The sum of all the angles of a triangle is 180 degrees.

If you add 90 + 90 + 90 together you get 270. These can not be the angle measures of interior angles of a triangle because the sum is more then 180.

If you add 80 + 80 + 200 together you get 360. These can not be the angle measures of interior angles of a triangle because the sum is more then 180.

If you add 40 + 50 + 60 together you get 150. These can not be the angle measures of interior angles of a triangle because the sum is less then 180.

If you add 15 +30 + 135 together you get 180! This set of angle measures can the be interior angles of a triangle!

Hope this helped!
