How do I solve number 12?

Answer:

the answer is {2, 3, 4, 5}

Step-by-step explanation:

3(2) + 1 > 4          3 times 2 is 6+1=7>4   anything above 2 works

3(3) + 1 > 4          

3(4) + 1 > 4          

3(5) + 1 > 4          

Answer:

D

Step-by-step explanation:

3x + 1 > 4

if x=1

3*1 + 1 > 4

3+1 > 4

4 not greater than 4

if x=2

3*2 + 1 > 4

6+1 > 4

7 > 4

if x=3

3*3 + 1 > 4

9+1 > 4

10 > 4

if x=4

3*4 + 1 > 4

12+1 > 4

13 > 4

if x=5

3*5 + 1 > 4

15+1 > 4

16 > 4

Thus, the set is [2,3,4,5], option 4 or D

Answer:

20%

Step-by-step explanation:

Answer: (1) There are 233 parking spots on the top level

(2) There are 72 parking spots reserved for drivers with disabilities

(3) There are 970 spots for hourly parking

(4) He would spend $7200 for parking in a year

Step-by-step explanation: In the first instance, there is a total of 1327 parking spots altogether allocated into various categories.

(1) There are 6 levels in all, and the first level has 162 parking spots. herefore the remaining 5 levels would have 1165 parking spots left as shown below;

Remainder = 1327 - 162

Remainder = 1165

If however the remaining 1165 parking spots are distributed equally among the other 5 levels, then each level would have 233 parking spots each as shown below;

Five levels = 1165

Each level = 1165/5

Each level = 233

Therefore the top level has 233 parking spots

(2) On each level (out of all 6 levels), there are 12 spots reserved for drivers with disability. Therefore at all parking levels you would have 72 spots as shown;

Reserved spot per level = 12

Reserved spot for 6 levels = 12 * 6

Reserved spot for 6 levels = 72

Therefore there are 72 spots reserved for driver with disability

(3) Other than the spots reserved for drivers with disability (72), there are 285 parking spots for monthly rental. The rest are for hourly parking, and this is calculated as shown;

Hourly parking + monthly rental + reserved parking = 1327

Hourly parking + 285 + 72 = 1327

Hourly parking + 357 = 1327

Hourly parking = 1327 - 357

Hourly parking = 970

Therefore there are 970 spots available for hourly parking.

(4) If the daily parking rate is $30, and Jack parks his car for 5 days in a week, then he would spend

30 * 5 = 150

If he parks for 4 weeks in a month, then he would spend

150 * 4 = 600

Therefore to pay for parking in a year (12 months) he would spend

600 * 12 = 7200

Therefore he would spend $7,200 for parking in a year

Answer:

two real roots

Step-by-step explanation:

y = -2x^2 + 9x - 7

This is in the form

ax^2 +bx+c

a = -2  b = 9  c = -7

The discriminant is

b^2 -4ac

(9)^2 - 4(-2) (-7)

81 - 56

25

Since the discriminant is greater than zero, there are two real roots

Answer:

The approximate solution to both systems is y = 17.03256 & x = - 10.074

Step-by-step explanation:

Because we have 2 equations we can simply graph each of them simultaneously and find the answer.

First we are going to graph y = - 0.44x + 12.6

Now.. We are going to graph y = - 7.21x - 55.6

Now that we have graphed both of our functions we know that the locations where the two lines meet otherwise known as the intersect is the solution to the equation.

Now that we know coordinate of x at the intersection point of the two lines is: - 10.074, we can input this number in as a substitute for our x because x = - 10.074

Therefor to verify,

y = - 0.44(-10.074) + 12.6

y = 17.03256

and now we substitute y into the other equation and find for x...

17.03256 = - 7.21x - 55.6

x = - 10.074

Answer:

x =1

Step-by-step explanation:

5x +7=12

5x=12-7

5x=5

x=1

The solution of the equation is 1.

A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.

Given equation;

5x +7=12

Subtract 7 on both side;

5x - 7 + 7 = 12-7

Divide by 5;

5x=5

or

x=1

The solution of the equation is 1.

Answer:

Δ OPQ ≅ Δ TSU

Step-by-step explanation:

Imagine if these two triangles were to line with one another, so that the lengths of sides QP, and US match knowing that they have similar lengths;

∠ O corresponds to that of ⇒ ∠T, provided they are each right angles,

∠ P corresponds to ⇒ ∠S, knowing that they share common side with length of 25 km so that they match,

Consecutively ∠Q  corresponds to ⇒ ∠U, for a similar reason,

Solution; Thus we can conclude that Δ OPQ ≅ Δ TSU

Answer:

15x + 14y + 36 = 0

Step-by-step explanation:

As we travel from the point (-8, 6) to the point (6, - 9), the increase in x (the "run") is 14 and that in y (the "rise") is -15.  Thus, the slope of the line segment connecting these two points is m = rise / run = -15 / 14.

Let's use the point (6, -9) and the slope m = -15/14 to write the equation of this line:

Adapting y = mx + b, we get:  

-9 = (-15/14)(6) + b, or

-9  = -45/7 + b, which yields b = 45/7 - 9, or  b = 45/7 - 63/7, or b = -18/7

Then the equation is y = (-15/14)x - 18/7

We must put this into "standard form."  Multiplying all three terms by 14 to clear the fractions out, we get:

14y = -15x - 36, or (in standard form):

15x + 14y + 36 = 0

Step-by-step explanation:

The point is located in the second quadrant because x is negative and y is positive. The quadrants are labeled in counter-clockwise order, starting in the upper-right

There is 0.25 is in the range of (0.18, 0.26), there is no statistical evidence that the program is not working as intended.

There is statistical evidence that the program makes the discount with a 0.25 probability.

The new margin of error is 0.02.

There is not statistical evidence that the program is working as intended.

Given that,

The program claims 22% of the receipts will get a discount in the long run.  

He selects a random sample and finds that 17% received the discount. The confidence interval is 0.17 ± 0.05 with all conditions for inference met.

According to the question,

The fact that 0.25 is in the range of (0.18, 0.26), there is no statistical evidence that the program is not working as intended.

The margin of error formula is z times the square rout of p-hat times 1 minus p hat over n.

From this formula  the me is inversely proportional to the square rout of the sample size. Because this is the case, the new me value is determined by dividing the old me value by 2 because of the fact that the proportion of p is 22%.

This means that the new me is equal to 0.04/2, which equals 0.02, which means that the new margin of error is 0.02.

This also equals(0 .22 - .02) ,(0 .22 - 0.02) or (0.2, 0.24) Because 0.25 is not within the range of (0.2, 0.24),

There is not statistical evidence that the program is working as intended.

Answer:

5

Step-by-step explanation:

For the point to be a solution to the equation, it has to lie on the line 5x -2y= 30 and therefore must satisfy the equation.

5x -2y= 30

When x=8,

5(8) -2y= 30

40 -2y= 30

40 -30= 2y (bring constant to 1 side)

2y= 10 (simplify)

y= 10 ÷2
