One week, Madelyn earned $265.60 at her job when she worked for 16 hours. If she is paid the same hourly wage, how many hours would she have to work the next week to earn $199.20?

Answer:

(1)-5x    (2)-3x and 0x

Step-by-step explanation:

(1)  -7x-2y=5

    -7x-12=5

(2)  y=-8x+5=-3x

     y=-5x+5=0x

9514 1404 393

Answer:

  24

Step-by-step explanation:

The product of lengths from the point where the secants meet to the near and far circle intersection points is the same for both secants.

  RQ·RC = RS·RT

  8(27) = (3x)(8x)

  9 = x^2 . . . . . . . . . divide by 24

  3 = x

Then the length of interest is ...

  TR = 8x = 8·3

  TR = 24

Step-by-step explanation:

A line graph, or a number line, has the numbers on different points along the graph. It's a little hard to explain since I can't draw one, but for x>=6, jut plot 6 on the number line as normal. Then since it could be equal to six, put a closed  circle (if it wasn't equal to then it would be an open circle).

Now since x is greater than, draw an arrow to the right (since the numbers increase the farther right you go). The follow the same idea for the other one.

Look at the Picture.

Step-by-step explanation:

Since the greater than sign is used, the circle will be filled in.

Since x is greater than the number, the line arrow will go in the direction of the number that is greater than it.

Step-by-step explanation:

Given

Dogs : Cats = 2 : 3

Required

Determine the possible number of dogs and cats at the store

The question requires options; since there are none, I'll answer on a general terms.

We have the dog to cat ratio to be:

Dogs : Cats = 2 : 3

Multiply ratio by any number (say 7)

Dogs : Cats = 2 * 7 : 3 * 7

Dogs : Cats = 14 : 21

This means that if there are 14 dogs, then there are 21 cats.

Multiply the ratio by another number (say 4)

Dogs : Cats = 2 * 4 : 3 * 4

Dogs : Cats = 8 : 12

This implies:

8 dogs and 12 cats

In conclusion, the number of dogs, when divided by the number of cats must equal ⅔.

Answer:

The temperature in 4 hours = -2 °F

Thus, option (D) is true.

Step-by-step explanation:

We know that the slope-intercept form of the line equation is

[tex]y = mx+b[/tex]

where m is the rate of change or slope and b is the y-intercept

Given that the current temperature outside = 10°F.

Thus, the y-intercept = b = 10°F

Given that as the day went on, It will fall at a constant rate of 3°F per hour.

Thus, the slope or rate of change = -3°F

(The rate of change or slope is -3 because the temperature is reducing)

Thus, the rate of change = slope = m = -3

Thus, substituting m = -3 and b = 10 in the equation

[tex]y = mx+b[/tex]

[tex]y = -3x + 10[/tex]

Now, substituting x = 4 to determine the temperature after 4 hours.

y = -3(4) + 10

y = -12 + 12

y = -2 °F

Therefore, the temperature in 4 hours = -2 °F

Thus, option (D) is true.

n is equal to the square root of 204

n=[tex]\sqrt{204}[/tex]

n=2[tex]\sqrt{51}[/tex]

Answer:

Well 180 divided by 15 is 12 so that said there would be 12 floors

So

1 floor 15

2 floor  30

3 floor  45

4 floor 60

5 floor  75

6 floor 90

7 floor  105

8 floor 120

9 floor 135

10 floor  150

11 floor  165

12 floor 180

Answer:

We accept with 99 % of confidence that p₁ ( the proportion in the group aged 18 - 34 ) is bigger than p₂ (the proportion in the group aged 35-44)

Step-by-step explanation:

Group aged  18 - 34

Sample size n₁  =  655  sample size enough to apply a normal distribution aproximation for the test

p₁ = 0,45      and   q₁ =  1 - p₁      q₁ = 0,55

p₁*n₁  =  0,45*655 = 294     q₁*n₁  = 0,55*655 = 360

both bigger than 5

p₁  = 45 %     or     p₁  = 0,45          then  q₁  = 1 - 0,45    q₁ = 0,55

Group aged 35 - 44

Sample size  n₂  =  420 sample size enough to apply a normal distribution aproximation for the test

p₂  =  37%   p₂ = 0,37     and    q₂  = 0,63

p₂*n₂  =  0, 37*420 =  155     q₁*n₁  = 0,63*420 = 264

Test Hypothesis

Null Hypothesis        H₀                                             p₁  =  p₂

Alternative Hypothesis Hₐ                                        p₁  >  p₂

Significance level    α  =  1%   α  = 0,01

Confidence Interval     CI = 99 %

Then   from z table  we find   critical z   z (c )  = 3,1

Calculating   z(s)

z(s)  =  (  p₁ - p₂ )/ √[ ( p₁*q₁)/n₁ ] + [ (p₂*q₂)/n₂ ]

z(s ) = (0,45 - 0,37 ) /  √ 0,45*0,55)/655  +  0,37*0,63 /420

z(s)  = 0,08  /0,03

z(s) = 2,66

Comparing  z(s)  and z(c)

z(s) < z(c)

Then z (s) is inside the acceptance region for H₀

Answer:

$3400

Step-by-step explanation:

800+(26x100)

Answer:

Because when your finding a point on the x line going left goes towards the negative side, like a number line. So for the y line think of it like the number line but going up is positive and going down is negative.

so if we wanted to go right 6 units and down 3 units it would written as:

(x+6,y-3) Because going right on the x line is like adding 6 units and going down on the y line is like subtracting 3 units for this example
