Answer:

exactly one half the area of the rectangle

Step-by-step explanation:

if you take a cross section then that means that you have put a diagnal line bisecting the rectangle in to two congruent triangles. meaning to find the area of the triangle you take 1/2b*h

meaning you would take the two sides of the triangle you know the length of. take 1/2 times one of them and multiply that answer by the other side length.

Answer:

<h2>The area of the cross-section that is parallel to side BFGC is 216 square centimeters.</h2>

Step-by-step explanation:

The graph wasn't provided. However, the image attached model the same problem but with different values. So, observe the process, it's gonna be the same.

The complete question is: <em>What is the area of a cross section that is parallel to face BFGC?</em>

<em />

<em> </em>In the image, you can observe that the side or face BFGC is at one side, and its dimensions are 36x6 in centimeters, because the base is 36 cm and its height is 6cm.

Now, we know that the defintion of the area of a rectangle is

$A=bh$ , where $b$ is the base and $h$ is the height. So,

$A=36cm(6cm)=216cm^{2}$

Therefore, the area of the cross-section that is parallel to side BFGC is 216 square centimeters.

Jack drove to work in the morning at an average speed of 45 miles per hour. He returned home in the evening along the same route

Dmitry [639]

Answer:

Step-by-step explanation:

Let's say that the time it took him to get to work in the morning is t hours. Then the time it took him to get home in the afternoon must be 1 - t hours. We know that for any trip, distance equals rate times time or d = rt . That means that the distance he drove to work is given by , but we also know that the distance he drove to get home must be the same distance, because he took the same route (and, presumably, no one picked up him house and moved it while he was at work) so for the trip home we can say d = 30 × (1 - t) and since the distances are equal, we can say:

45t = 30 × (1 - t)

45t = 30 - 30t

45t + 30t = 30

75t = 30

t = 30/75

t = 2 /5 hour to drive to work at 45mph

Since , d = rt

d = 45 ×(2/5) = 18miles

A researcher is interested in knowing whether responses to lowering the legal age for drinking alcohol varies by gender. Which s

likoan [24]

The statistical test that would be most appropriate determine the answer the researcher is interest in knowing is a chi-square test.

<h3>What is a chi-square test?</h3>

A chi-square test is a statistical test used to test the relationship between categorical variables. It is used to determine the difference between the expected data and the observed data is due to chance.

Chi squared = $\frac{(O_{i} - E_{i} )^{2} }{E_{i} }$

Where:

$O_{i}$ = observed value
$E_{i}$ = expected value.

The researcher is interested in knowing if the response to lowering the legal age for drinking alochol (observed value)) varies by gender (expected value). Thus, a chi-square test would be used.
