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

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.)
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

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
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

m=p/n+4 make n the subject
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]
