b. if each admission ticket costs $2.50, then marco and his friends spent $22.50 in all. TRUE OR FALSE????

Answers

Answer 1

Answer: True

Step-by-step explanation:

Cost = 15 + 3t

22.5 = 15 + 3(2.5)

22.5 = 15 + 7.5

22.5 = 22.5 <— true

Answer 2

Answer:

true

Step-by-step explanation:

2.50 x 3 = 7.50

15 + 7.50 = 22.50

22.50 = 22.50

Find the equation of a line which is parallel to y= 2/5 x + 17 and passes through (-15,12)

Answers

Answer:

y = 2/5x + 18.

Step-by-step explanation:

The line will have the same slope of 2/5.

Using the point-slope form of a line:

y - 12 = 2/5(x - -15)

y - 12 = 2/5(x + 15)

y = 2/5x + 6 + 12

y = 2/5x + 18.

Answer:

y = (2/5)*x + 18

Step-by-step explanation:

Because the line is parallel to the line y = 2/5 x + 17, the slope of the new line has to be the same as well. So far, we have y = (2/5)*x .

Now what we can do is plug in -15 for x and see what we get for y. Because we get -6, we need 18 more to make it 12. Because of that, the y-intercept is 18 to make the equation of the line y = (2/5)*x + 18.

The graph shows a volume of ice cubes versus temperature in degrees celsius. Which of the statements is false?

A. The correlation coefficient is close to zero.

B. Temperature is strongly correlated to the volume of ice cubes.

C. Temperature is the explanatory variable.

D. The data show a negative linear relationship.

Answers

The statements which is false about the volume of ice cubes versus temperature graph is the correlation coefficient is close to zero.

What is the correlation coefficient?

Correlation coefficient is used to calculate how strong the relationship is between the two variables.

When there is a statistical relationship between two or more variables, then they are said to be in correlation.

Types of correlation-

Positive correlation coefficient- When the value of correlation coefficient is positive, then the value of one variable increases with increase in other variable.Negative correlation coefficient- When the value of correlation coefficient is negative, then the value of one variable decreases with increase in other variable.

The graph shows a volume of ice cubes versus temperature in degrees Celsius.

For a perfect correlation, -1 or +1 values is ideal. Here, some relation can be seen in a negative straight line, which suggest that the correlation coefficient is not close to zero.

Both volume and temperature has strong correlation for linear line where, temperature is the explanatory variable.

Thus, the statements which is false about the volume of ice cubes versus temperature graph is the correlation coefficient is close to zero.

Carlita is flying a kite at the beach. She wants to know the altitude of the kite when she uses 25 yards of string at an angle of elevation of 56°. Find the altitude of Carlita's kite to the nearest hundredth.
13.98 yards

20.73 yards

30.16 yards

37.06 yards

Please Answer as soon as you can I am giving 50 points!

Answers

Answer:

Step-by-step explanation:

13.98

The altitude of Carlita's kite to the nearest hundredth should be considered as the 13.98 yards when she uses 25 yards of string at an angle of elevation of 56.

Calculation of the altitude of Carlita's kite:

Since she uses 25 yards of string at an angle of elevation of 56°

So we know that

cos 56 degrees = 0.5592

Now the altitude is

= (25) (0.5592)

= 13.98 yards

We basically multiplied these two so that the altitude should come.

hence, the first option is correct.

Jay makes a base salary of $2000 per month. Once he reaches $50000 in total sales, he earns an additional 5% commission (salary) on the amount of sales over $50000. Let s be the amount of his total sales for the month and j(s) be the amount of his salary for the month.

Answers

Answer:

[tex]j(s) = 0.05s -500[/tex]

Step-by-step explanation:

Given

[tex]Base\ Salary = 2000[/tex]

[tex]Commission = 5\%[/tex] on Sales over 50000

Required

Determine the function j(s) for sales over 50000

Represent the total sales in a month with s.

Sales over 50000 in that month will be: s - 50000

So, the function j(s) is:

j(s) = Base Amount + Commission * Sales over 50000

[tex]j(s) = 2000 + 5\% * (s - 50000)[/tex]

Convert % to decimal

[tex]j(s) = 2000 + 0.05 * (s - 50000)[/tex]

Open bracket

[tex]j(s) = 2000 + 0.05 * s - 0.05 * 50000[/tex]

[tex]j(s) = 2000 + 0.05s - 2500[/tex]

Collect Like Terms

[tex]j(s) = 0.05s - 2500 + 2000[/tex]

[tex]j(s) = 0.05s -500[/tex]
