at 6:00 a.m., the temperature is 58°. At 2:00 p.m., temperature is 76°. Find the rate of change in degrees per hour during this time.

Answers

Answer 1

Answer:

The rate of change is of 2.25 degrees per hour.

Step-by-step explanation:

The rate of change in degrees per hour is given by by the change in temperature divided by the change in time(by number of hours).

In this question:

From 6 am to 2 pm, there are 12 - 6 + 2 - 0 = 6 + 2 = 8 hours

The change in temperature was of 76 - 58 = 18º

Rate of change:

18º/8 = 2.25º

The rate of change is of 2.25 degrees per hour.

Equations
Show all work

Answers

Answer:

Number of ducks = 37

Number of pigs = 18

Step-by-step explanation:

Let,

x be the number of ducks

y be the number of pigs

According to given statement;

x+y=55     Eqn 1

2x+4y=146     Eqn 2 (As ducks will have 2 legs and pigs will have 4)

Multiplying Eqn 1 by 2

2(x+y=55)

2x+2y=110    Eqn 3

Subtracting Eqn 3 from Eqn 2

(2x+4y)-(2x+2y)=146-110

2x+4y-2x-2y=36

2y=36

Dividing both sides by 2

[tex]\frac{2y}{2}=\frac{36}{2}\\y=18[/tex]

Putting y=18 in Eqn 1

x+18=55

x = 55-18

x = 37

Hence,

Number of ducks = 37

Number of pigs = 18

How can you use the distributive property to rewrite 15p+10q as a product?

Answers

Answer:

Both of those terms are divisible by 5, so you could express it also as

5(3p + 2q)

The equivalent expression is [tex]5(3p+2q)[/tex].

Important information:

The given expression is [tex]15p+10q[/tex].

We need to find the equivalent expression by using the distributive property.

Distributive property:

According to the distributive property:

[tex]a(b+c)=ab+ac[/tex]

The given expression can be written as:

[tex]=5\times 3p+5\times 2q[/tex]

[tex]=5(3p+2q)[/tex]

Therefore, the equivalent expression is [tex]5(3p+2q)[/tex].

An analyst wants to determine the relationship between speed, in miles per hour, and the time, in hours, it takes to drive 5 miles. Twenty trials are completed and the correlation coefficient between speed and time is determined to be -0.276. Therefore, slower speed was related to greater time. How is the correlation affected if the units for time are changed from hours to minutes?

Answers

Answer:

Answer below:

Step-by-step explanation:

SPEED (in miles/hour),  TIME (in hours)

This analyst determined the relationship between the 2 measures above, using 20 trials.

The correlation coefficient between both factors was -0.276

Now, correlation coefficient is a figure that shows the strength and direction of two quantities. The quantities here are speed and time.

The minus sign in this correlation coefficient shows a negative movement of one quantity against the other. In other words, as one quantity moves up, the other goes down, and vice versa. An increase in magnitude of speed will result in a decrease in magnitude of time spent driving. Vice versa.

If you plot speed against time, the graph (that joins each point of intersection of speed and time together) will slope downwards showing the opposing movements of time and speed.

How is the correlation affected if the units for time (time only, not speed) are changed from hours to minutes?

If the units for each time measured are changed to minutes while that of speed is left in hours, the magnitude of each time measured will increase by 60.

For example, if three of the twenty trials have the following values for time -  1.5 hours,  2.3 hours,  3.6 hours

then they will be multiplied by 60, in order to change to minutes. The new values are shown below:

90 minutes,  138 minutes,  216 minutes

THIS CHANGE ON THE VARIABLE TIME ALONE, WILL CAUSE IT TO CARRY MORE MAGNITUDE WHILE THE TIME IN THE MEASUREMENT OF SPEED REMAINS THE SAME.

WHAT THIS WILL DO TO THE CORRELATION COEFFICIENT IS: to lower the value of the figure from 0.276 to a value like 0.043

The minus sign will still remain, as speed and time are still moving in opposite directions.

The value of the correlation coefficient will drop!

The students at view side elementary school had a read a thon the teachers kept track of how many books the students in each grade level read estimate the total number of books the students read round each number to the nearest hundred to help you find your answer
Kindergarten 247, first grade 385 , second grade 1347 and third grade 1549

Answers

Answer:

Estimate = 3400 books

Step-by-step explanation:

Given that:

Books read by students.

Kindergarten 247

First grade 385

Second grade  1347

Third grade 1549

We have to round the each number to nearest hundred.

247 rounded to the nearest hundred is 200.

385 rounded is 400

1347 rounded is 1300

1549 rounded is 1500

Total = 200 + 400 + 1300 + 1500 = 3400

Hence,

Estimate = 3400 books



Internetlivestats.com reported in December 2017 around 41% of the world population has an Internet connection today. If there are
3,062,263,517 users, what is the world population? (Round your answer to the nearest whole number.)

Answers

Answer:

World population = 7,468,935,407

Step-by-step explanation:

Given that:

Percent of people who have internet connection = 41%

Number of people who have internet connection = 3,062,263,517

Let,

x be the world population.

41% of x = 3062263517

[tex]\frac{41}{100}x=3062263517\\[/tex]

0.41x = 3062263517

Dividing both sides by 0.41

[tex]\frac{0.41x}{0.41}=\frac{3062263517}{0.41}\\x=7468935407[/tex]

Hence,

World population = 7,468,935,407

Select the correct answer. A basketball team played 15 games and won 80% of them. If the team expects to play 30 games in all, how many more games must it win to finish the season with a 90% winning percentage? O A 12 B. 14 Ос. D. US​

Answers

Answer:

12 more games

Step-by-step explanation:

15 + 12 = 27

27 is 90% of 30 , so they need to win 12 more games but 27 overall out of the 30

30 = 100%

27 = x

x = 27×100%/30

x = 2700%/30

x = 90%

Answer:

[tex] n = \frac {p - 4m}{m} [/tex]

Step-by-step explanation:

Given the algebraic expression;

[tex] m = \frac {p}{n + 4} [/tex]

To make n the subject of formula.

Cross-multiplying, we have;

[tex] m*(n+4) = p [/tex]

[tex] mn + 4m = p[/tex]

Rearranging the equation, we have;

[tex] mn = p - 4m [/tex]

[tex] n = \frac {p - 4m}{m} [/tex]

Answer:

[tex]m = \frac{p}{(n + 4)} \\ (n + 4)m = p \\ nm + 4m = p \\ nm = p - 4m \\ n = \frac{p - 4m}{m} \\ n =( \frac{p}{m} - 4)[/tex]

n=p/m-4 is the right answer.
