Answer 1
Answer:

Answer:

108

Step-by-step explanation:

Mike's current age, be M

Then Brandon's is: M - 27

Also, M = 4(M - 27)

M = 4M - 108

M - 4M = - 108

- 3M = - 108

from 1970 to 1980 the consumer price index increased from 38.8 to 82.4. If a container of onion dip cost $0.48 in 1970 and the price of onion dip increased at the same rate as the CPI from 1970 to 1980, by approximately how much did the price of a container of onion dip increase from 1970 to 1980

Answers

We need to find the percent increase from 38.8 to 82.4, so

x * 38.8 = 82.4
x = 82.4/38.8
x = 2.1237

Multiply by 100 to convert to percentage (move decimal 2 places to the right)

2.1237 = 212.37%

Now we can apply this percentage increase to the onion dip...

0.48 x 212.37% =
0.48 x 2.1237 = 1.019 
 
Round to the nearest cent $1.02 is the amount of increase.  Now add it to the original price to get today's price...

$1.02 + .48 = $1.50

Which equation represents this number sentence?Fourteen more than the quotient of a number and 5 is 23.

Answers

Answer:

The answer to your question is: the second option

Step-by-step explanation:

a) This is not the right answer, the sentence to this option could be: fourteen more than the quotient of five and a number is 23.

b) This is the right option, the sentence is given in the description.

c)  This is not the right answer, the sentence to thi option could be: the quotient of fourteen plus a number and five is 23.

d) This is not the right answer, the sentence of this option could be: the quotient of five and the addition of a number and fourteen is 23.

Final answer:

The equation representing the given number sentence is x/5 + 14 = 23.

Explanation:

The number sentence is "Fourteen more than the quotient of a number and 5 is 23." To represent this as an equation, we need to translate the words into mathematical symbols. Let's say the number is represented by x. The quotient of a number and 5 is x/5. Fourteen more than x/5 is x/5 + 14. So, the equation representing the number sentence is x/5 + 14 = 23.

The scatter plot shows the number of minutes each of 28 people played a video game and the number of levels each person completed in the video game. Which statement is best supported by the scatter plot? Please help me!!!

Answers

Answer:

28 people played a video game

Step-by-step explanation:

Final answer:

The statement supported by the scatter plot depends on the pattern of the data points. A positive correlation means as playing time increases, so do levels completed, while a negative correlation would mean the opposite. A linear regression model can also be used for a precise interpretation if the data align along a straight line.

Explanation:

The scatter plot, in the context of this question, is a graphical representation showing the relationship between the number of minutes each person played a video game (independent variable, x-axis) and the number of levels each person completed in the video game (dependent variable, y-axis). The best statement that can be made from the scatter plot would depend on the pattern that the data points form.

If the scatter plot shows a positive correlation, this means that as the number of minutes played increases, the number of levels completed also increases. If the plot shows a negative correlation, this means the more minutes played, the lesser the number of levels completed. If there is no discernible pattern in the data, we would say there is no correlation between the time played and levels completed. Furthermore, the strength of these correlations can be assessed based on how close the data points cluster to a theoretical line of best fit.

For a more precise interpretation, we could also look into employing a linear regression model if the data seems to align along a straight line, divining a mathematical relationship between x and y.
