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)

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

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

Answer: Hello, There! your Answer is Below

A (x - 4)(x - 9)

Step-by-step explanation:

Find p, and q, knowing sum = b = 13 and product c = 36. Compose factor pairs of 36-> (2, 18)(2, 12)(4, 9). this last sum is 9 = b. Then p = 4 and q = 9

Hope this Helps you!!

Have a great day!!

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

Step-by-step explanation:

6*10=60+40=100

100[tex]\geq[/tex]100

Answer:

C

Step-by-step explanation:

In order to graph we must first simplify the inequality

40 + 10x ≥ 100

step 1 subtract 40 from each side

40 - 40 cancels out

100 - 40 = 60

we now have 10x ≥ 60

step 2 divide each side by 10

10x/10 = x

60 / 10  = 6

we're left with x ≥ 6

Now to graph

We will start with a closed circled on 6 and because the inequality sign is facing the varibale (x) the line will go in the direction of the right

Thus, the answer is C

Answer:

r = 11 makes 2r - 7 = 15 true.

Step-by-step explanation:

2r - 7 = 15

Add 7 to both sides.

2r = 22

Divide by 2.

r = 11

Proof:

2r - 7 = 15

2(11) - 7 = 15

22 - 7 = 15

15 = 15

Answer:

There is no greatest power of 3 that is divisible of 100.

Step-by-step explanation:

Since any number can always be divisible of 100, there would be no greatest power of 3 that is divisible of 100 since the powers can go on and on forever without stopping, and all powers of 3 is able to be divided by 100.

For 11 :

Now , We'll find the Base :

Area of Triangle = 1/2 × b × h :

30.2 = 1/2 × b × 7.2

30.2 = 3.6 × b

30.2 / 3.6 = b

8.3 in = b

Now , we can say that the base is 8.3 in .

For 12 :

Area of Triangle = 1/2 × b × h :

25.5 = 1/2 × 11.1 × h

25.5 = 5.5 × h

25.5 / 5.5 = h

4.6 cm = h

Now , we can say that the height is 4.6 cm .

Answer:

$5,956.2

Step-by-step explanation:

First we need to find the amount after 5years using the formula

A =P(1+r)^n

A = 9000(1+0.06)^5

A = 9000(1.06)^5

A = 9000(1.3382)

A = 12,043.8

Interest after 5 years = 12,043.8 - 9000

Interest after 5 years = 3,043.8

Since it will be worth 6% less each year, the amount after 5years will be 9000 - 3,043.8 = $5,956.2
