PLS HELP IM FAILING MY MATH CLASS

Answer:

TRUE

Step-by-step explanation:

In a function, every domain value (x-value) must have exactly one corresponding range value (y-value). This means that in a function, an x-value or input value cannot have two different y-value or output value. Or else, it ceases to be a function.

So, when you substitute a certain value of x into the equation of a function, you can only have one exact value of y for that value of x.

Answer:

x = 128

x - 23 = 105°

Step-by-step explanation:

x - 23° = 105° because these angles are corresponding

x = 105 + 23

x = 128

The value of the angle marked x - 23 = 105

Answer:

  363

Step-by-step explanation:

The n-th term of an arithmetic sequence is given by ...

  an = a1 +d(n -1)

Here, the first term (a1) is -92, and the common difference is (-85 -(-92)) = 7. The 66th term is ...

  a66 = -92 +7(66 -1) = -92 +455

  a66 = 363

Answer:

ok so they had lot of money and then they went down

Step-by-step explanation:

so i think what happen was that they started off at day 1 with 500 dollars around and then they went down to 285 and then 210 around there, so that can mean they must of wasted money on something or something else on the account

Answer:

a. ST and UV are perpendicular lines.

b. BC and DE are parallel.

c. NP and QR are neither parallel nor perpendicular.

d. GH and JK are parallel.

Step-by-step explanation:

Slopes are used to calculate steepness of a line. Slopes are also used to check if two lines are parallel, perpendicular or neither.

When two lines are parallel, their slopes are equal.

When two lines are perpendicular, product of slopes of both lines is -1

Slope is given by the formula:

[tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]

a) S(-4, -1), T(-1,5) and U(1,1), V(5, -1)

[tex]Slope\ of\ ST = \frac{5+1}{-1+4} = \frac{6}{3} = 2\\Slope\ of\ UV = \frac{-1-1}{5-1} = \frac{-2}{4} = -\frac{1}{2}[/tex]

Now,

[tex](Slope\ of\ ST)(Slope\ of\ UV) \\= 2 * -\frac{1}{2}\\=-1[/tex]

ST and UV are perpendicular lines.

b) B(-6, -2), C(-3, 3) and D(2,0), E(5,5)

[tex]Slope\ of\ BC = \frac{3+2}{-3+6} = \frac{5}{3}\\Slope\ of\ DE = \frac{5-0}{5-2} = \frac{5}{3}[/tex]

As the slopes of two lines is equal, BC and DE are parallel.

c) N(-6,2), P(--3, -4) and Q(1, -3), R(3, 4)

[tex]Slope\ of\ NP = \frac{-4-2}{-3+6} = \frac{-6}{3} = -2\\Slope of\ QR = \frac{4+3}{3-2} = \frac{7}{2}[/tex]

NP and QR are neither parallel nor perpendicular.

d) G(-2,5), H(4,1) and J(1, –4), K(7,0)

[tex]Slope\ of\ GH = \frac{1-5}{4+2} = \frac{-4}{6} = -\frac{2}{3}\\Slope\ of\ JK = \frac{0-4}{7-1}= \frac{-4}{6} = -\frac{2}{3}[/tex]

GH and JK are parallel.

Hence,

a. ST and UV are perpendicular lines.

b. BC and DE are parallel.

c. NP and QR are neither parallel nor perpendicular.

d. GH and JK are parallel.

A study done by researchers at a university concluded that ​70% of all student-athletes in this country have been subjected to some form of hazing. The study is based on responses from 1800 athletes. What are the margin of error and​ 95% confidence interval for the​ study?

Answer:

Step-by-step explanation:

Given that:

The sample proportion [tex]\hat p = 0.70[/tex]

The sample size n = 1800

At 95% confidence interval level:

The level of significance = 1 - 0.95 = 0.05

Critical value: [tex]Z_{0.05/2} = Z_{0.025} = 1.96[/tex]

Thus, the Margin of Error E = [tex]Z_{\alpha/2} \times \sqrt{\dfrac{\hat p ( 1- \hat p)}{n}}[/tex]

[tex]= 1.96 \times \sqrt{\dfrac{ 0.70 ( 1-0.70)}{1800}}[/tex]

[tex]= 1.96 \times \sqrt{\dfrac{ 0.70 ( 0.30)}{1800}}[/tex]

[tex]= 1.96 \times \sqrt{\dfrac{0.21}{1800}}[/tex]

[tex]= 1.96 \times \sqrt{1.16666667\times 10^{-4}}[/tex]

the Margin of Error E = 0.021

At 95% C.I for the population proportion will be:

[tex]= \hat p \pm Z_{\alpha/2} \sqrt{\dfrac{\hat p(1- \hat p)}{n}}[/tex]

= 0.70 ± 0.021

= (0.70 - 0.021, 0.70 + 0.021)

= 0.679, 0.721)

Step-by-step explanation:

ok but what's the question

Answer:

C

Step-by-step explanation:

your y values which produce the range differ between 2 and 10 which means that will be your range. All of the values are real.

Answer:

A=85

B=58

Step-by-step explanation:

NO. OF 2 point basket⇒ A

NO. OF 3 point basket⇒B

A+B=89⇒ EQN 1

A=27+B

A-B=27⇒EQN 2

EQN 1 - EQN 2

2B=116

B=58

THEREFORE

 A=27+58

A=85
