C.
2512 cm

D.
1256 cm

Answers

Answer:

-4

Step-by-step explanation:

Parallel lines are lines that run across from each other but never intersect. For this to work, they must change at the same rate and have the same slant. This means parallel lines must have equal slopes; therefore, the slope of the parallel line is -4. It is also important to note that parallel lines must have different y-intercepts, or they would just be the same line.

Would someone please help me? Ravi decides to eliminate just 100 calories per day from his diet. He knows that each pound of body fat equals 3500 calories. How long will it take for Ravi to lose 10 pounds?

Answers

Answer:

350 days

Step-by-step explanation:

If Ravi is eliminating 100 calories per day, and one pound of body fat is 3500 calories, then it will take him 35 days to lose one pound of body fat.

Multiply 35 by 10 to find how long it will take for him to lose 10 pounds:

35(10)

= 350

So, it will take him 350 days to lose 10 pounds.

A student would like to estimate the proportion of students at his school who have lunch during period 4. To do so,
he selects a random sample of 40 students and finds that 30% of them have period 4 lunch. Later, he goes to the
guidance office and finds that of the 380 students at this school, 25% of them have period 4 lunch. Which of the
following properly describes the number, 25%?
sample
statistic
population
parameter
Yeah

Answers

Answer:

D

As we are getting the 25% from the whole population of 380 students, therefore this is a population proportion which is a parameter. Note that we get parameter from population and statistic from the sample.

Step-by-step explanation:

The property parameter describes the number, 25% because  25% from a population of 380 students, this is a population proportion that may be used as a metric option (D) parameter is correct.

What are population and sample?

It is described as a collection of data with the same entity that is linked to a problem. The sample is a subset of the population, yet it is still a part of it.

We have:

Number of samples = 40

30% of them have period 4 lunch.

Total population = 380

25% of them have period 4 lunch.

Because we're collecting 25% from a population of 380 students, this is a population proportion that may be used as a metric.

We collect parameters from the population and statistics from the sample.

Thus, the property parameter describes the number, 25% because  25% from a population of 380 students, this is a population proportion that may be used as a metric option (D) parameter is correct.

Answers

Answer: I just did the test so the answer is A. 5.8 units

What is length of line segment?

The distance between any two points is the length of the line segment joining the points.

The formula for the distance, D, between two points whose coordinates are (x₁, y₁) and (x₂, y₂)

D = √((x2 – x1)² + (y2 – y1)²)

This is called the Distance Formula.

Given,

Coordinates of points Q (8, 2) and R (5, 7)

Length of QR = Distance between point Q and point R.

D = √((x2 – x1)² + (y2 – y1)²)

D = √((5 - 8)² + (7 - 2)²)

D = √(-3² + 5²)

D = √9 + 25

D = √34

D = 5.83 units

Length of QR rounded to one decimal = 5.8 unit

Hence, 5.8 unit is closest to the length of QR = 5.83units

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

- 4x + 3y = 12 ( add 4x to both sides )

3y = 4x + 12 ( divide the terms by 3 )

y = [tex]\frac{4}{3}[/tex] x + 4 ← in slope- intercept form

with slope m = [tex]\frac{4}{3}[/tex] and y- intercept c = 4

---------------------------------------------------

Given

- 5x + 3y = - 9 ( add 5x to both sides )

3y = 5x - 9 ( divide the terms by 3 )

y = [tex]\frac{5}{3}[/tex] x - 3 ← in slope- intercept form

with slope m = [tex]\frac{5}{3}[/tex] and y- intercept c = - 3

Write the equation in standard form for the circle with radius 4 centered at the origin

Answers

Answer:

common form to write the equation of a circle in is the center-radius form. The center-radius form is: (x−h)2+(y−k)2=r2 Here, the center point is denoted by (h,k) and r is the radius of the circle. The first example he does is: Find the center and radius of the circle given by the equation (x−2)2+(y+4)2=25.

Answer:

x² + y² = 16

Step-by-step explanation:

We need to write the standard equation of circle with , centre (0,0) and radius 4 unit . The Standard equation of the circle ⭕ is ,

=> ( x - h)² + (y -k)² = r²

=> ( x -0)² + (y-0)² = 4²

=> x² + y² = 16 .

• Hence the equation of the circle is x² + y² = 16.

According to the line plot, what is the total amount of time spent studying by the students who studied for an hour each?

Answers

Answer:

2.5 hours

Step-by-step explanation:

The total amount of time studying by students who spent 1/2 an hour studying is the product of the number of students who spent 1/2 an hour studying by 1/2 an hour.

Hence, counting the number of dots on the point marked 1/2 gives the count of students who spent 1/2 an hour studying and multiply this number by 1/2.

Total amount of hours spent = 1/2 * 5 = 2.5 hours

Step-by-step explanation:

When we round to the nearest thousand, we have to look which thousand is closer to the value. So in our case 67795 is 205 away from 68 000 and is 795 away from 67000. From this we know that 68 000 is closer, therefore if we round 67 795 to the nearest thousand we will get 68 000.
