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:

(-3,-9)

Step-by-step explanation:

X goes first then Y, since they are both negative they go backwards on the graph

1.) Crown pls ;)

A.) The domain is (-∞,∞) or (-infinity, infinity)

B.) The range is (0,∞) or (0, infinity)

C.) The y-intercept is (0,6)

D.) x-axis

E.) Base

2.)

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:

A sample of 1077 is required.

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which

z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].

The margin of error is of:

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

42% of freshmen do not visit their counselors regularly.

This means that [tex]\pi = 0.42[/tex]

98% confidence level

So [tex]\alpha = 0.02[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.02}{2} = 0.99[/tex], so [tex]Z = 2.327[/tex].

How large of a sample size is required?

A sample size of n is required, and n is found when M = 0.035. So

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

[tex]0.035 = 2.327\sqrt{\frac{0.42*0.58}{n}}[/tex]

[tex]0.035\sqrt{n} = 2.327\sqrt{0.42*0.58}[/tex]

[tex]\sqrt{n} = \frac{2.327\sqrt{0.42*0.58}}{0.035}[/tex]

[tex](\sqrt{n})^2 = (\frac{2.327\sqrt{0.42*0.58}}{0.035})^2[/tex]

[tex]n = 1076.8[/tex]

Rounding up:

A sample of 1077 is required.

The equation of f(x) is f(x)= −43​x−3, the correct option is C.

Function is a type of relation, or rule, that maps one input to specific single output.

In mathematics, a function is an expression, rule, or law that describes the relationship between one variable (the independent variable) and another variable (the dependent variable) (the dependent variable). In mathematics and the physical sciences, functions are indispensable for formulating physical relationships.

Linear function is a function whose graph is a straight line

We are given that;

f(x) = -3/X-1

Now,

To find the equation of f(x), we need to identify the slope and the y-intercept of the line. The slope is the ratio of the vertical change to the horizontal change between any two points on the line. The y-intercept is the value of f(x) when x = 0.

Looking at the graph, we can see that f(x) passes through the points (-8, 3) and (0, -3). The slope can be calculated as:

slope=run rise​= 0−(−8) f(0)−f(−8)​=0+8−3−3​=8−6​=−43​

The y-intercept can be found by plugging in x = 0 into the equation f(x) = slope  x + y-intercept and solving for y-intercept:

f(0)=−43​x0 + y-intercept

−3=y-intercept

Therefore, by the given function the answer will be f(x)=−43​x−3.

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:

x= 34

Step-by-step explanation:

(4x + 1 )° + 43° = 180° (due to linear pair)

4x+1+43 = 180

4x + 44 = 180

4x = 180 - 44

4x = 136

x = 136 ÷ 4

therefore, x = 34

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

The similar triangles

Required

Solve for x

TUV to TLM implies that, the corresponding sides are:

[tex]TU \to TL[/tex]

[tex]TV \to TM[/tex]

[tex]UV \to LM[/tex]

To solve for x, we use the following equivalent ratios

[tex]TV : TM =TU:TL[/tex]

This gives:

[tex]24 : x + 8=36 : 24[/tex]

Express as fraction

[tex]\frac{24 }{ x + 8} =\frac{36 }{ 24}[/tex]

Cross Multiply

[tex]36(x + 8) =576[/tex]

Divide both sides by 36

[tex]x + 8 =16[/tex]

Subtract 8 from both sides

[tex]x = 8[/tex]

FGH to WVU implies that, the corresponding sides are:

[tex]FG \to WV[/tex]

[tex]FH \to WU[/tex]

[tex]GH \to VU[/tex]

To solve for x, we use the following equivalent ratios

[tex]FH : WU =FG:WV[/tex]

This gives:

[tex]x + 3 : 5 = 27 : 9[/tex]

Express as fraction

[tex]\frac{x + 3 }{ 5 }= \frac{27 }{ 9}[/tex]

[tex]\frac{x + 3 }{ 5 }= 3[/tex]

Cross Multiply

[tex]x + 3 = 3 * 5[/tex]

[tex]x + 3 = 15[/tex]

Subtract 3 from both sides

[tex]x = 12[/tex]

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

Answer:

Simple interest is the cost of using or borrowing money without compound interest or interest on interest. Simple interest works in your favor when you're a borrower because it keeps the overall amount that you pay lower than it would be with compound interest

Step-by-step explanation:

Answer:

Simple Interest is considered "Simple" due to it's straight-forward method; where you add your annual interest rate (%) to your initial principal value, instead of compound which you add your annual interest rate (%) onto your new principal value.

Simple interest is usually used to calculate their first year interest ($).
