Text- Many egg producers keep chickens in small cages that do not allow the chickens to move. Some people believe that this is unhealthy, so they buy eggs from chickens that are not caged 24-hours a day. These are sometimes called "free-range" chickens. The United States Department of Agriculture (USDA) allows chickens to be called free-range as long as the chickens spend some of their time outside. The European Union (EU), however, has several additional restrictions. One of these is that the farmers must provide enough outside area so that if all the chickens were outside, the density of chickens would be no more than 0.25 chickens/sq meter.

2 pointsFind the x-and y-intercepts of the following equation: 5x – 3y = 15
O (15,0) and (0, -15)
0 (-5,0) and (3,0)
0 (0.-5) and (3,0)
0 (0.3) and (-5,0)

Answers

The x - intercept of 5x - 3y = 15 is (3, 0)

The y -intercept of 5x - 3y = 15 is (0, -5)

Solution:

Given equation is 5x - 3y = 15

To find: x - intercept and y -intercept

The x intercept is the point where the line crosses the x axis. At this point y = 0

The y intercept is the point where the line crosses the y axis. At this point x = 0.

Finding x - intercept:

To find the x intercept using the equation of the line, plug in 0 for the y variable and solve for x

So put y = 0 in given equation

5x - 3(0) = 15

5x = 15

x = 3

So the x - intercept is (3, 0)

Finding y - intercept:

To find the y intercept using the equation of the line, plug in 0 for the x variable and solve for y

So put x = 0 in given equation

5(0) - 3y = 15

-3y = 15

y = -5

So the y - intercept is (0, -5)

Amanda selected 18 pea pods at random from a bag containing about 500 pea pods. She opened each pod and counted the number of peas in the pod.What is the estimated mode of the number of peas to be found in all the pea pods?

A.
8

B.
8.5

C.
9

D.
10

Answers

Answer: Option 'C' is correct.

Step-by-step explanation:

Since we have given that

Total number of pea pods = 500

Number of pea pods selected = 18

She opened each and counted the number of peas in the pod.

So, we can see from the graph, that

And we know that Mode is the most occurring outcome among the total.

6 peas in 1 bag.

7 peas in 3 bags

8 peas in 5 bags

9 peas in 6 bags

10 peas in 3 bags

There are 9 peas in the 6 bags is the most occurring part.

So, Estimated mode of the number of peas to be found in all the pea pods is 9.

Hence, Option 'C' is correct.

Answer: The answer is C. 9

Step-by-step explanation: The mode is the number that shows up the most

What is the largest positive integer value of m such that the equation 3x^2 - mx + 7 = 0 has no real solutions?

Answers

use determinant
in form ax²+bx+c=0
when b²-4ac>0, it has 2 real roots
when b²-4ac=0, it has 1 real root
when b²-4ac<0, it has no real roots
so

we solve for no real roots
b²-4ac<0
a=3
c=7
b=-m

(-m)²-(4)(3)(7)<0
m²-84<0
add 84 both sides
m²<84
sqrt both sides
m<9.1 about
nearest integer
round down
m=9

answer is m=9

Mack designed a water fountain with a square pyramid flowing into a cube. The edges of the bases of the pyramid and the cube have the same length and the heights of the pyramid and the cube are the same. Describe the relationship between the volume of the cube and the volume of the pyramid.

Please help me on this question. There are six questions in total and I did the rest (finding the volume/surface area) but this one I just don't understand. I'm willing to give up 60 of the 70 points I have for help (help that tells me the answer and explains it). Maybe even all 70. Please help if you understand. Thank you, minna.

Answers

volume of pyramid = 1/3 b2h
volume of cube = b3

now , provided pyramid and cube have same edges and same heights.

thus, volume of pyramid = 1/3 b3
volume of cube = b3.

thus, ratio = 1/3b3/ b3 = 1/3.

Thus, volume of pyramid = 1/3volume of cube

$V_(cube)=a^3\ \ \ and\ \ \ V_(pyramid)= (1)/(3) \cdot a^2\cdot h=(1)/(3)a^3\n \n (V_(pyramid))/(V_(cube)) = ((1)/(3)a^3)/(a^3)= (1)/(3)\n \n \nA_(cube)=6a^2\n \nh^2=a^2+( (1)/(2) a)^2\ \ \ \Rightarrow\ \ \ h^2= (5a^2)/(4)\ \ \ \Rightarrow\ \ \ h= (a √(5) )/(2)\n\nA_(pyramid)=a^2+4\cdot (1)/(2)ah=a^2+2a\cdot (a √(5) )/(2) =a^2(1+ √(5)) \n \n (A_(pyramid))/(A_(cube))= (a^2(1+ √(5)) )/(6a^2) = (1+ √(5))/(6)$
