Does this graph represent a function?

Answer:

the total monthly cost is $742.36

Step-by-step explanation:

The computation of the total monthly cost is shown below:

= Mortgage payment + insurance + taxes + electricity + phone service + fuel + water + repairs

= $347.90 + $17 + $84 + $64.40 + $33.50 + $98.25 + $17.44 + $79.87

= $742.36

Hence, the total monthly cost is $742.36

Step-by-step explanation:

We start by stating the null hypothesis

H0: p1 = p2

No difference is existent

H1: p2 not equal to p2

There is a difference

We find the z statistic using microsoft excel or using the formula in the attachment

= -1.68

From the normal table, p value = 0.099

The p value is greater than 0.05 so we fail to reject the null hypothesis and conclude there is no difference

B. If answer in part a is incorrect then we have made a type ii error. A type 2 error occurs when we accept a false null hypothesis.

What you do is $18,000 x 5% which is 900 and then you do 900 x 10 = 9000!

Answer:

10 students in Kindergarten

Step-by-step explanation:

20% is equal to 1/5

1/5 x 50 = 10 or 50 ÷ 5 = 10

Answer:

D) -2

Step-by-step explanation:

Slope = -3

(1, -9)

y - y1 = m(x - x1)

y + 9 = -3(x - 1)

y + 9 = -3x + 3

y = -3x - 6

y = -3x - 6

0 = -3x - 6

6 = -3x

x = -2

3 + 2 + 1 = 6

270 ÷ 6 = 45

45 × 3 = 135

45 × 2 = 90

45 × 1 = 45

3 : 2 : 1

135 : 90 : 45

Answer:

60.2 grams is remaining after 7 minutes.

Step-by-step explanation:

Exponential equation for amount of substance:

The exponential equation for the amount of a substance is given by:

[tex]A(t) = A(0)(1-r)^t[/tex]

In which A(0) is the initial amount and r is the decay rate, as a decimal, and t is the time measure.

An element with mass 510 grams decays by 26.3% per minute.

This means that [tex]A(0) = 510, r = 0.263[/tex]

So

[tex]A(t) = A(0)(1-r)^t[/tex]

[tex]A(t) = 510(1-0.263)^t[/tex]

[tex]A(t) = 510(0.737)^t[/tex]

How much of the element is remaining after 7 minutes?

This is A(7). So

[tex]A(7) = 510(0.737)^7 = 60.2[/tex]

60.2 grams is remaining after 7 minutes.

C 37.5

Step-by-step explanation:

1 inch is 30 feet. so feet is 30 x [number of inches]. 30 x 1.25 = 37.5

Answer:

16.75

Step-by-step explanation:

20/60=x/360

x=120 degree angle

120/360=x/2pi8

1/3=x/16pi

16pi/3=x

x=16.75 arc length

Answer: Find the measures of an exterior angle and an interior angle given the number of sides of each regular polygon. Round to the nearest tenth, if necessary. 24 b 15, 345 24, 156 7.5, 172.5 15, 165​

Step-by-step explanation:  sum, S, of the measure of the interior angles of a polygon with n sides is: ... The sum of the interior angles of a 24 -gon is 3960. ... angles of a polygon is (n−2)⋅180 , where n is the number of sides. ... Each exterior angle measures 36024=15 . ... The sum of the 24 interior angles is then 24⋅165=3960 .

Answer:

20 visits.

Step-by-step explanation:

Fitness Universe has a 1 time payment of $50, and each visit will cost $5.50

Non-members pay $8 per visit. Let each visit be signified by the variable, v. Set the equation:

5.50v + 50 = 8v

Isolate the variable, v. Note the equal sign, what you do to one side, you do to the other. Subtract 5.50v from both sides:

5.50v (-5.50v) + 50 = 8v (-5.50v)

50 = 8v - 5.50v

50 = 2.50v

Isolate the variable, v. Divide 2.50 from both sides:

(50)/2.50 = (2.50v)/2.50

v = 50/2.50

v = 20

Stuart must visit 20 times to break even, in which it will become cheaper after the 20th visit.

Answer:

Option A is the answer buddy

Step-by-step explanation:

Answer:

a is the answer boi

Step-by-step explanation:

Answer:

a = 2

b = 1

c = 1

Step-by-step explanation:

The quadratic equation, 2x² + x + 1 = 0, is expressed in the standard form as ax² + bx + c, where a ≠ 0.

Thus,

a = 2

b = 1 (1 * x = x)

c = 1

Answer:

The condensed log equation is: [tex]\log{\frac{x^4y}{z^5}}[/tex]

Step-by-step explanation:

We use these following logarithm properties to solve this question:

[tex]a\log{x} = \log{x^a}[/tex]

[tex]\log{a} + \log{b} = \log{ab}[/tex]

[tex]\log{a} - \log{b} = \log{\frac{a}{b}}[/tex]

In this question:

[tex]4\log{x} = \log{x^4}[/tex]

[tex]5\log{5} = \log{z^5}[/tex]

So

[tex]4\log{x} + \log{y} - 5\log{z}[/tex]

Becomes:

[tex]\log{x^4} + \log{y} - \log{z^5}[/tex]

Now applying the addition and subtraction properties, we have:

[tex]\log{\frac{x^4y}{z^5}}[/tex]

The condensed log equation is: [tex]\log{\frac{x^4y}{z^5}}[/tex]

Answer:

08255555/10000000 this is the answer

Answer:

0.8255555 = [tex]\frac{33}{40}[/tex]

Step-by-step explanation:

Showing the work

Rewrite the decimal number as a fraction with 1 in the denominator

0.825 = [tex]\frac{0.825}{1}[/tex]

Multiply to remove 3 decimal places. Here, you multiply top and bottom by 103 = 1000

[tex]\frac{0.825}{1}[/tex] × [tex]\frac{1000}{1000}[/tex] = [tex]\frac{825}{1000}[/tex]

Find the Greatest Common Factor (GCF) of 825 and 1000, if it exists, and reduce the fraction by dividing both numerator and denominator by GCF = 25,

[tex]\frac{825/25}{1000/25}[/tex] = [tex]\frac{33}{40}[/tex]

Therefore

X= [tex]\frac{33}{40}[/tex]

In conclusion,

0.825555 = [tex]\frac{33}{40}[/tex]

Solving for the elapsed time

distance traveled = (speed of first train + speed of second train) * elapsed time

280 miles = (95 mph + 105 mph) * elapsed time

280 miles = 200 mph * elapsed time

elapsed time = 280 miles / 200 mph

elapsed time = 1.4 hours

elapsed time = 1 hour and 24 minutes

It will take 1 hour and 24 minutes for the two trains to be 280 miles apart.

Answer:

y - 7 = 1/2(x - 7)

Step-by-step explanation:

Point slope form is y - y1 = m (x - x1)

So find m = y2 - y1/ x2 - x1, so m = -1 - 7 / -9 - 7, m = -8 / -16 so m = 1/2

Then sub your (7,7) so y - 7 = 1/2(x - 7)
