Mr. Ramirez informs the students that some of the trees they plant will not survive their first year, so the class will take precautions to monitor the trees to give them the best chance of survival.

Abby does some research and finds that, on average, 3 out of every 25 trees planted will die their first year.

What percentage of the trees will survive their first year?

Answers

Answer 1

The percentage of trees that will survive are 26%

Answer 2

Answer:

88%

Step-by-step explanation:

Since 25 is 1/4 of 100, you can simply subtract 3 from 25 and then, your answer from that you want to multiply it by 4. Or you can make it into a fraction if that helps you visualize what's going on. It'll be 22 over 25, now multiply both numerator and denominator by 4.

of $36.90. Write and solve an equation to determine how
many cookies she sold.

Answers

Answer:

.70x + 14.50= 36.90 x=32

Step-by-step explanation:

0.7x=36.9-14.5

0.7x=22.4

x=32

Answer:

i believe the correct answer here is 53

Step-by-step explanation:

so if 1 cookie is 70 cents, then you determine how many cookies is $36.90

you use proportion and say(convert to cents)

70: 1

3690: more

and calculating using proportion, you get 52.714285714286 and when you round it off it's 53. to prove your answer you say 0.7 × 52.7 = 36.9

Supplementary angles add to 180

So, the angle supplementary to the angle of 112 degrees measures 68 degrees.

If these two lines are parallel, the angles are the same.

So, the triangle has angle measures: 2x, 68, and 68.

2x+68+68=180

2x=44

x=22

Given line 1, with coordinates (-7,-3) and (4,7), and line
2 with coordinates (7,-7) and (-3, 4), find the slope of line 2

Answers

Answer:

-11/10 (fraction) or -1.1 (decimal)

Step-by-step explanation:

The slope formula is m=(y2-y1)/(x2-x1)

x1 = 7

x2 = -3

y1 = -7

y2 = 4

So, it’s: (4 - (-7))/(-3-7)

= (4+7)/(-3-7)

= (11)/(-10)

= -11/10 or -1.1

A clothing company is interested in the relationship between the number of sales per month for its employees (y) and price. Based on the collected data, the least-squares regression line is ŷ = 9.74 + 4.89x, where x is the number of dollars by which price exceeds $25. Which of the following statements best describes the meaning of the slope of the least-squares regression line?

Question 3 options:

1)

For each increase in price of $1, the estimated number of sales per month increases by 4.89.

2)

For each increase in price of $1, the estimated number of sales per month increases by 9.74.

3)

For each increase of one sale per month, there is an estimated increase in price of $4.89.

4)

For each increase of one sale per month, there is an estimated increase in price of $9.74.

5)

The slope has no meaning because the units of measure for x and y are not the same.

Answers

Answer:

1) For each increase in price of $1, the estimated number of sales per month increases by 4.89

Step-by-step explanation:

Using linear function concepts, it is found that the statement that best describes the meaning of the slope of the least-squares regression line is:

1) For each increase in price of $1, the estimated number of sales per month increases by 4.89.

Linear function:

A linear function is modeled by:

[tex]y = mx + b[/tex]

In which:

m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0.

In this problem, the equation is:

[tex]y = 9.74 + 4.89x[/tex]

The slope is of 4.89, which means that when x(number of dollars by which price exceeds $25) changes by 1, y(number of sales per month) increases by 4.89, hence option 1 is correct.

Answers

Answer:

Monthly payment= $440.71

Step-by-step explanation:

Giving the following information:

Mothly interest rate (i)= 0.025/12= 0.00208

Number of periods (n)= 12*10= 120 months

Future Value (FV)= $60,000

To calculate the monthly payment, we need to use the following formula:

Monthly payment= (FV*i) / [(1+i)^(n) - 1]

Monthly payment= (60,000*0.00208) / [(1.00208^120) - 1]

Monthly payment= $440.71
