Answer:

C.4.5 ft^2

Step-by-step explanation:

If the area of the whole circle is 18 ft^2, and a whole circle is 360 degrees, and you are looking for the area of 90 degrees of that circle (which is one fourth of the circle) you would divide the area by 4, to get the area for that sector.

360/90= 4: meaning that 90 degrees is 1/4 of a circle.

So, you would divide 18 by 4.

18/4=4.5

Hope this helps!

Answer:

It would be C

Step-by-step explanation:

since the whole area of the circle is 18 and the sector takes up one-fourth of the circle you would just divide 18 by 4 to get 4.5

The boundary lines for the system of inequalities is given in the graph.

diamong [38]

Answer:

region C

Step-by-step explanation:

We have to use what is called the zero-interval test [test point] in order to figure out which portion of the graph these inequalities share:

$\displaystyle y ≤ -x + 2$

0 ≤ 2 ☑ [We shade the portion of the graph that CONTAIN THE ORIGIN, which is the bottom portion.]

$\displaystyle y ≥ 2x - 3$

0 ≥ −3 ☑ [We shade the portion of the graph that CONTAINS THE ORIGIN, which is the left side.]

So, now that we got that all cleared up, we can tell that both graphs share a region where the ORIGIN IS VISIBLE. Therefore region C matches the above inequalities.

Give the null and alternative hypotheses in symbolic form that would be used in a hypothesis test of the following claim:

irakobra [83]

Answer:

Step-by-step explanation:

The null hypothesis is usually the default statement. The alternative is the opposite of the null and usually tested against the null hypothesis

In this case study,

The null hypothesis in would be that the mean time between clicks of the second hand on a particular clock is 1 second. In symbolic form it would be u = 1

The alternative hypothesis would be that the mean time between clicks of the second hand on a particular clock is 1 not second. In symbolic form, it would be: u =/ 1

Tariq left his house and drove to the store. He stopped and went inside. From there, he drove in the same direction until he got

choli [55]

Based on the graph (see attachment), Tariq is 4 minutes after he left his house, until he got back home.

<h3>What is distance?</h3>

Distance can be defined as the amount of ground covered (traveled) by a physical object or body over a specific period of time, regardless of its direction, starting point or ending point.

<h3>What is a graph?</h3>

A graph can be defined as a type of chart that's commonly used to graphically represent data on both the horizontal and vertical lines of a cartesian coordinate, which are the x-axis and y-axis.

By critically observing the graph (see attachment) which models the time that elapses over the distance covered by Tariq, we have:

Time = 10 minutes - 6 minutes

Time = 4 minutes.

In conclusion, we can infer and logically deduce that Tariq is 4 minutes after he left his house, until he got back home.
