Answer:

B. Ordinal

Step-by-step explanation:

The level of measurement used for a variable in statistical analysis determines what summary statistics and analysis are possible. In statistical analysis, we have three types of level of measurement.

Nominal , Ordinal  , Interval/ Ratio

The nominal is the most basic level of measurement. It is the  qualitative level of measurement such as color or number.  Data in Nominal scale of measurement are  stored as a word or  as numerical code.

Ordinal level of measurement  are variables based on ranks or hierarchy. Ordinal level of measurement posses a sequential step-wise order but the intervals between the variables are not  equal. They are usually expressed in frequencies.

Therefore, the level of measurement of variable that determines the livability rankings for cities based on their ranks or hierarchy is Ordinal.

The interval/ratio level of measurement  is the highest  level of measurement where  data are  being measured and ordered in a sequential process.

Answer: The square root of 225 is 15.

Explanation:  the square root of a number is the value that, when multiplied by itself, gives the original number. In this case, the original number is 225. To find the square root of 225, we need to find a number that, when multiplied by itself, equals 225. That number is 15, because 15 x 15 = 225. Therefore, the square root of 225 is 15.

Answer: 25%.

Step-by-step explanation:

According to the problem it states that the original price is 48 dollars which is 100% cost. We know that 12 is 1/4 of 48 so 1/4 of 100% gives 25%.

Answer:

y+4

Step-by-step explanation:

Alexandre, this is the solution:

Let's recall that the interior angles of a rhombus add up to 360 degrees.

Upon saying that, we have:

4x + 3x + 31 + 6x - 90 + 7x + 19 = 360

20x - 40 = 360

Adding 40 at both sides:

20x - 40 + 40 = 360 + 40

20x = 400

Dividing by 20 at both sides:

20x/20 = 400/20

x = 20

Now, we can calculate each of the angles and prove they add up to 360 degrees, as follows:

• 4x = 4 * 20 =, 80

• 3x + 31 = 3 * 20 + 31 = 60 + 31 =, 91

• 7x + 19 = 7 * 20 + 19 = 140 + 19 = ,159

• 6x - 90 = 6 * 20 - 90 = 120 - 90 = ,30

80 + 91 + 159 + 30 = 360

Answer:

27

Step-by-step explanation:

Let T be the capacity of the tank.

Since the tank was 1/3 full and ends up 7/9 full.

         \(\frac{7}{9}\)T - \(\frac{1}{3}\)T = 12  

Simplifying the left side of the equation, tells us how much 12 gallons fills.

         \(\frac{4}{9}\)T = 12

Now we solve for T:

         T = 12*9/4

         T = 27

Answer:

your answer is gonna be 579 miles that would be your answer

The ground speed will be 454.2 mph in north east.

The quantity which has magnitude, direction and follows the law of vector addition is called a vector.

Given that airplane is flying with a constant altitude at a speed of 450 mph in a direction 10° north of west directly towards its final destination.

The airplane then encounters wind blowing at a steady 34 mph in a direction 85° north of east.

The component of an airplane will be

x =450  sin 10

x = -244.8

y = 450  cos 10

x = -377.5

The component of wind will be

x =34sin 85

x = -5.98

y = 34 cos 85

x = -33.4

Then the ground speed will be 454.2 mph in north east.

The unit rate of discovery of the new species of marine animals are; 2000 per year.

There is independent quantity, and a quantity which depends on it (dependent quantity). When independent quantity moves by a unit measurement (single unit increment), the increment in dependent quantity is called rate of increment of dependent quantity per unit increment in independent quantity.

We have been given about 4000 new species of marine animals were discovered in the last 2 years.

We need to find the unit rate of discovery.

Total = 4000 new species

Time = 2 year.

Unit rate = new species of marine animals/ time period

Unit rate = 4000/ 2

Unit rate = 2000/1

Therefore, the unit rate of discovery of the new species of marine animals are; 2000 per year.

a) The percentage of the new income allocated to housing is approximately 19%. Option C

b) Following the same approach as before, we can determine that the percentage of the new income allocated to insurance is also 23%. Option B

To determine the percentage of the new income allocated to housing, we need to compare the amount allocated to housing with the total new income.

a) Based on the given information, the family's monthly budget is $5,400, and housing expenses account for 19% of the budget.

If we assume that their previous monthly income was X dollars, and their raise increased their monthly income by 10%, the new monthly income would be 1.10X dollars.

Since the family decides to keep their monthly expenses the same, their housing expenses remain at 19% of the new income, which is 0.19 * 1.10X = 0.209X dollars.

To find the percentage of the new income allocated to housing, we divide the housing expenses (0.209X dollars) by the total new income (1.10X dollars) and multiply by 100:

(0.209X / 1.10X) * 100 = 0.19 * 100 ≈ 19%

Rounding to the nearest percent, the percentage of the new income allocated to housing is approximately 19%.

Therefore, the correct answer is C) 19%.

b) For the second question, we need to find the percentage of the new income allocated to insurance. Based on the given information, insurance expenses account for 23% of the monthly budget.

Following the same approach as before, we can determine that the percentage of the new income allocated to insurance is also 23%.

Therefore, the correct answer is B) 23%.

The value of x in degrees will be 6° and 11° using properties of parallel lines.

They are typically equal-distance, parallel straight lines. The lines here are parallel. They never come together no matter how far you extend them in any one way.

Pairs of equal-sized angles that are both obtuse or acute and are generated on the same side of the transversal are known as corresponding angles. Each pair of comparable angles on the same side of the crossing transversal is equal to the other.

The alternative angle theorem states that alternate interior angles or alternate exterior angles that come from cutting two parallel lines are congruent.

In the above figure,

8x + 7 = 55

8x  = 55 - 7

x = 6

Measure of the angle will be 8 × 6 + 7 = 49

In 11)

10x + 10 = 9x + 21 (by using first corresponding angles and then alternate angles)

⇒x = 11

4 out of 10 = 40%

Answer: The two numbers that multiply to -65 and add to -8 are -13 and 5.

Steps: Here are the steps to find two numbers that multiply to -65 and add to -8:

Write down the equation x * y = -65 where x and y are the two numbers you’re looking for.

Write down the equation x + y = -8.

Solve for one of the variables in one of the equations. For example, solving for x in the second equation gives us x = -8 - y.

Substitute this expression for x into the first equation: (-8 - y) * y = -65.

Solve this quadratic equation for y: -y^2 - 8y + 65 = 0.

Use the quadratic formula to find the values of y: y = (-(-8) +/- sqrt((-8)^2 - 4 * (-1) * 65)) / (2 * (-1)).

This gives us two possible values for y: -13 and 5.

Substitute these values back into one of the original equations to find the corresponding values of x. For example, when y = -13, we have x = -8 - (-13) = 5. When y = 5, we have x = -8 - 5 = -13.

So, the two numbers that multiply to -65 and add to -8 are -13 and 5.
