Step-by-step explanation:
Let the width of the rectangular plot be x then the length will be 4x.
Perimeter of the rectangular plot = 360m
We know that,
Perimeter = 2*(l + b) where l=length and b = breadth
360 = 2*(4x+x)
or, 360= 2* 5x
or, 360 =10x
or, x = 36
Hence the width = x = 36m
And the length = 4x
= 4*36
=144m

Step-by-step explanation:
The complete question is attached
Solution
All f(x) values are not negative hence, option A is incorrect
All g(x) values are the greatest among the three f(x), g(x) and h (x), hence option B is correct
The range of all three functions is different. Hence, option C is incorrect
All h (x) values are negative. Hence, Option D is correct

Answer:
Step-by-step explanation:
a. Y intercept is where the line crosses the y axis, so for l1 it’s (0,4). Answer is 4.
b. Y intercept for l2 is point (0,2). Answer is 2.
c. l1 gradient is -1/2. Rise/run
So l1 equation is y = -1/2x + 4
l2 gradient is 1.
Equation is y = x + 2
e. x+2= -1/2x + 4
1.5x = 2
x = 1.333...
y = plug into one of the equations value of x. So y = 3.333...
f. 1.33+ 2 = 3.33
-1/2 times 1.33 + 4 = 3.33 (rounded)
graph a line with slope 1/3 and y-intercept -2
Find the slope (m) and y-intercept (b) of each line.
Answer:
y-int:(0,-2)
slope: 5/2
Step-by-step explanation:
slope is rise over run, so you just need to find 2 points (0,-2) and (2,3) and calculate (3-(-2))/(2-0) and get 5/2. y intercept is just the point located at X=0
Answer:
The y-intercept is (0, -2) and the slope is 5/2

The American Water Works Association reports that the per capita water use in a single-family home is 69 gallons per day. Legacy Ranch is a relatively new housing development. The builders installed more efficient water fixtures, such as low-flush toilets, and subsequently conducted a survey of the residences. Thirty-six owners responded, and the sample mean water use per day was 64 gallons with a standard deviation of 8.8 gallons per day.
Required:
At the 0.10 level of significance, is that enough evidence to conclude that residents of Legacy Ranch use less water on average?
Answer:
The pvalue of the test is 0.0083 < 0.1, which means that there is enough evidence to conclude that residents of Legacy Ranch use less water on average
Step-by-step explanation:
The American Water Works Association reports that the per capita water use in a single-family home is 69 gallons per day. Test that the residents use less water.
At the null hypothesis, we test that the mean is 69, that is:
[tex]H_0: \mu = 69[/tex]
At the alternate hypothesis, we test that the mean is less than 69, that is:
[tex]H_a: \mu < 69[/tex]
The test statistic is:
As we have the standard deviation for the sample, we use the t-statistic.
[tex]t = \frac{X - \mu}{\frac{s}{\sqrt{n}}}[/tex]
In which X is the sample mean, [tex]\mu[/tex] is the value tested at the null hypothesis, s is the standard deviation and n is the size of the sample.
69 is tested at the null hypothesis:
This means that [tex]\mu = 69[/tex]
Thirty-six owners responded, and the sample mean water use per day was 64 gallons with a standard deviation of 8.8 gallons per day.
This means that [tex]n = 36, X = 64, s = 8.8[/tex]
Value of the test statistic:
[tex]t = \frac{X - \mu}{\frac{s}{\sqrt{n}}}[/tex]
[tex]t = \frac{64 - 69}{\frac{8.8}{\sqrt{36}}}[/tex]
[tex]t = -3.41[/tex]
Pvalue of the test and decision:
The pvalue of the test is the probability of finding a mean less than 64, which is the pvalue of t = -3.41, found on the t-table with 36 - 1 = 35 degrees of freedom on a one-tailed test.
With calculator help, the pvalue is 0.0083.
The pvalue of the test is 0.0083 < 0.1, which means that there is enough evidence to conclude that residents of Legacy Ranch use less water on average

Jane loves animals. She has an equal number of beetles, birds and spiders as pets. Apart from human legs, there is a total of 270 legs in the house. How many spiders dies jane have if a spiders has 8 legs and a beetle has 6 legs?
b = number of beetles
r = number of birds
s = number of spiders
"She has an equal number of beetles, birds and spiders". That means b = r = s. They all stand in for the same number, and that number being some positive whole number.
One spider has 8 legs, so s of them have 8s legs. One beetle has 6 legs, so b of them have 6b legs. One bird has 2 legs, so r birds have 2r legs.
In total, all of the animals have 6b+2r+8s legs. We'll replace r and s with b, since earlier we were given that b = r = s.
So we end up with:
6b+2r+8s
6b+2b+8b
(6+2+8)b
16b
The number of legs of all the animals is equal to 16 times the number of beetles. Set this equal to 270 and isolate b
16b = 270
b = 270/16
b = 16.875
We run into a problem. It's not possible to have the variable b equal to a non-whole decimal number like this. It's possible your teacher made a typo somewhere. I would ask them for clarification.

Barak asked 50 students which type of flower they liked best. The results are displayed in the pie chart. If Barak asked 200 students which flower they liked best, how many students would you predict would choose tulips?
A. 15
B. 30
C. 60
D. 67
Answer:
C. 60 among 200 students would like Tulip (Assuming pie chart - 15 among 50 students like Tulip)
Step-by-step explanation:
Percent students liking tulip = (Tulip liking students / Total students) x 100
= (15 / 50) x 100 = 30%
Expected students to like Tulip among 200 students = 30% of 200
( 30 / 100 ) x 200
= 60 students
Answer this for 10 points

A commuter crosses one of three bridges, A, B, or C, to go home from work. The commuter crosses bridge A with probability 1/3, crosses bridge B with probability 1/6, and crosses bridge C with probability 1/2. The commuter arrives home by 6pm with probability 75%, 60%, and 80% by crossing bridge A, B, or C, respectively. If the commuter arrives home by 6pm, find the probability that bridge B was used.
Answer:
0.1333 = 13.33% probability that bridge B was used.
Step-by-step explanation:
Conditional Probability
We use the conditional probability formula to solve this question. It is
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]
In which
P(B|A) is the probability of event B happening, given that A happened.
[tex]P(A \cap B)[/tex] is the probability of both A and B happening.
P(A) is the probability of A happening.
In this question:
Event A: Arrives home by 6 pm
Event B: Bridge B used.
Probability of arriving home by 6 pm:
75% of 1/3(Bridge A)
60% of 1/6(Bridge B)
80% of 1/2(Bridge C)
So
[tex]P(A) = 0.75*\frac{1}{3} + 0.6*\frac{1}{6} + 0.8*\frac{1}{2} = 0.75[/tex]
Probability of arriving home by 6 pm using Bridge B:
60% of 1/6. So
[tex]P(A \cap B) = 0.6*\frac{1}{6} = 0.1[/tex]
Find the probability that bridge B was used.
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.1}{0.75} = 0.1333[/tex]
0.1333 = 13.33% probability that bridge B was used.

Find the value of c that makes each trinomial a perfect square. Then write the trinomial as a perfect square.
6. x2 – 20x + c
a. c = 64; (x – 8)2 b. c = 20; (x – 10)2 c. c = 100; (x + 10)2 d. c = 100; (x – 10)2
Answer:
d. c = 100; (x – 10)²
Step-by-step explanation:
Note that (x+a)²=x²+2ax+a².
In our case, 2a=-20, so 'a' must be -10.
Since c=a², and a=-10, c=(-10²)=100.
Since a=-10, the perfect square is (x – 10)²
