Answer:

The coordinates of P'Q'R' are: P' (2,8), Q' (1,4) ,R'(4,1)

Step-by-step explanation:

We are given:

The vertices of a triangle are P(2, –8), Q(1, –4), and R(4, –1).

We need to:

Name the vertices of P'Q'R' after a reflection over the x-axis.

Reflection over the x-axis

The rule used for reflection over x-axis

P(x,y)= P'(x,-y)

The coordinates of x-axis remains same, while coordinates of y-axis become negative.

Now, finding coordinates of P'Q'R'

P (2,-8) -> P' (2,8)

Q(1,-4) -> Q' (1,4)

R(4,-1) -> R'(4,1)

So, the coordinates of P'Q'R' are: P' (2,8), Q' (1,4) ,R'(4,1)

Answer: The slope of the line is [tex]\frac{3}{4}.[/tex]

Step-by-step explanation: I use the slope formula to find the slope of the line given the graph image below that looks like this:[tex]\frac{Rise}{Run}=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}.[/tex]  

The rise of the points is 3 points and the run of the points is 4 points.

Now I can put it in another slope formula that looks like this: [tex]\frac{3-0}{2-(-2)}=\frac{3}{4}.[/tex]

I hoped my answer was found very helpful to your own question and have more understanding and happy Halloween! :D

Answer:

Step-by-step explanation:

you have a pentagon , and the sum of the angles is 540

3x-10+3x-8+5x-2+3x+1+2x+15=16x-4=540

16x-4=540

16x=544

x=544/16=34

the angle= (3x-8)=(3*34)-8=94

Answer:

15 cups

Step-by-step explanation:

The formula to find cups from quarts C = Q * 4, where c is how many cups, and Q how many quarts. To find how many cups are in a quart, simply multiply the number of quarts by 5. In this case, there are 3 3/4 quarts of coffee, multiply that by 5, and you would get 15 cups of coffee!

Answer:

The answer tot he question provided is 5.

Step-by-step explanation:

→ Angle D and Angle B are congruent to each other, which means that they are equal.

→ The equation would look like:

[tex]2x + 4 = 4x - 6[/tex]

→ Solve the equation.

[tex]2x + 4 = 4x - 6 \\ \frac{ - 4x \: \: \: \: = - 4x \: \: \: \: \: \: \: \: \: }{ - 2x + 4 = - 6} \\ \frac{ \: \: \: \: \: \: \: \: \: \: \: - 4 = - 4}{ \frac{ - 2x}{ - 2} = \frac{ - 10}{ - 2} } \\ x = 5[/tex]

→ The value of x results in being 5.

Answer:

35 degrees

Step-by-step explanation:

Answer:

a)  p*n =  46     and  q*n  =  454 data is enough for inference

b) CI =  (   0,099 ;  0,141)

c) CI we will find with 90% of confidence the value of p in that interval

d) No, we accept H₀  we don´t have evidence to claim that the percentage in the State University is smaller than that of the Department of Education

Step-by-step explanation:

Information from A state´s Department of Education is:

p₀  =  12 %    p₀ = 0,12

The State University sample:

Sample size   n  = 500

Sample proportion   46   out of 500      

p  =  46/500     p =  0,092     then    q =  1- p   q  =  1 - 0,092    q = 0,908

Both    p*n =  46     and  q*n  =  454

a) Are big enough to approximate the binomial distribution to normal distribution

b) CI = 90%   CI = 0,9     significance level  α = 0,10  for an CI we need

α/2   =  0,10/2      α/2 = 0,05

z(c)  =  - 1,64     ( from  z-table)

MOE  =  z(c)*√(p*q)/n

MOE  =   1,64 * √ ( 0,092*0,908)/500

MOE  =  1,64 *√0,08353/500

MOE  =  1,64 * 0,0129

MOE  = 0,021

Then  CI = 90 % is:

CI  =  (  0,12 -  0,021   <  P  <  0,12 + 0,021 )

CI =  (   0,099 ;  0,141)

We have with 90 % of confidence for finding the value of p in the interval

Test Hypothesis

Null Hypothesis                        H₀             p  =  p₀

Alternative Hypothesis            Hₐ             p < p₀

we have  for  α = 0,1     z(c)  =  - 2,32  from z table

And  z(s)  = ( p  -  p₀  ) /  √ (p*q)/n

z(s)  = ( 0,092 - 0,12 ) / √(0,092*0,908)/500

z(s)  =  - 0,028 / 0,0129

z(s)  =  - 2,17

Comparing  z(s)  and  z(c)  we see that

|z(s)| < |z(c)|

So  z(s) is in the acceptance region. We can support the claim that the percentage in the State University is the same than that of the Departament of Education

She deposited $16,000 at 4% and $32,000 at 4.5%

She deposited $16,000 at 4% and $32,000 at 4.5%.

Let's assume Liza deposited an amount x at 4% interest. According to the given information, she deposited twice as much, which is 2x, at 4.5% interest.

To calculate the interest income from the deposits, we'll use the formula: Interest = Principal × Rate × Time.

At 4% interest, the interest earned is 0.04x (4% expressed as a decimal multiplied by x).

At 4.5% interest, the interest earned is 0.045(2x) (4.5% expressed as a decimal multiplied by 2x).

We know that the total annual interest income is $2080. Therefore, we can write the equation:

0.04x + 0.045(2x) = 2080

Simplifying the equation:

0.04x + 0.09x = 2080

0.13x = 2080

x = 2080 / 0.13

x ≈ 16,000

Liza deposited approximately $16,000 at 4% interest, and since she deposited twice as much at 4.5% interest, she deposited approximately $32,000 at 4.5% interest.

Therefore, she deposited $16,000 at 4% and $32,000 at 4.5%.

Answer:

n = 20

Step-by-step explanation:

Since the triangles are similar, we can create a common proportion.

[tex]\frac{15}{12} =\frac{n}{16}[/tex]

Now you have to solve this proportion

Start by cross multiplying, and you get 12n = 240

Divide both sides by 12, and you get n = 20.

Hope this helped

Hey there!

The answer to your question is n = 20

Since they are similar, we can use proportions:

12/15 = 16/n

Then we can use cross products:

15 x 16 = 12n

140 = 12n

20 = n

Answer:

d is greater than c, since at [tex]x = 0, g(x) > f(x)[/tex]

Step-by-step explanation:

We are given two exponential functions, f(x) and g(x).

Since f has the higher base(3 instead of 2 in g), it increases faster, so initially, g is greater than f, and after point (p,q), f is greater than g.

The values of c and d are found when [tex]x = 0[/tex]. At this point, we have that  function g is greater than function f, which means that d is greater than c.
