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.

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

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:

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:

The amount of tax is $14.37 and the tax rate percentage is 12.18%

Step-by-step explanation:

Find the amount of tax by finding the difference between the cost and selling price:

132.37 - 118

= 14.37

Find the tax rate percentage by dividing the tax by the original cost, and multiplying it by 100:

(14.37/118) x 100

= 12.18

The amount of tax is $14.37 and the tax rate percentage is 12.18%

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)

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:

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:

4/8

Step-by-step explanation:

There are an infinite number of fractions equal to 1/2, but the number line in the question has 8 spaces, and shows 1 divided into 8 pieces. Therefore, the answer to this question is likely 4/8.

(may I ask why exactly this is put as a college level problem?)

Answer:

It should still be the same point.

Step-by-step explanation:

It should still be the same point, since the line did not increase in length, but the numbers of units has, and that does not affect the position of the half of the line.

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
