Answer:
25%
Step-by-step explanation:
We are given that
Initial height of sunflower=160 cm
After increasing
Final height of sunflower=2m
We have to find the percentage increase in height.
1 m=100 cm
[tex]2m=2\times 100=200cm[/tex]
Increase in height of sunflower=Final height of sunflower-initial height of sunflower
Increase in height of sunflower=200-160=40cm
Percentage increase=[tex]\frac{Increase\;value}{Initial\;value}\times 100[/tex]
Using the formula
Percentage increase in height=[tex]\frac{40}{160}\times 100[/tex]
Percentage increase in height=25%

Please help me wit this
Answer:
1. Equation: y = -1.17491x + 81.791 (you may need to round!)
2. Correlation coefficient: -0.8566
3. Strong negative correlation because the correlation coefficient is close to -1
4. Sketch the scatterplot using north latitude as the x value and Jan mean temp as the y value on the graph
Step-by-step explanation:
Step 1: Go to desmos graphing calculator
Step 2: Insert a table
Step 3: Insert values into the table (shown in image) using the north latitude as the x value and jan mean temp as y value
Step 4: Go to line 2, and type "[tex]y_1 = mx_1 + b[/tex]" except replace "=" with ~ as shown in the image. Put the 1s as subscripts
Step 5: Scroll out. Desmos would've graphed the line of best fit and plotted the points. Under statistics, you can see that r is the correlation coefficient
Step 6: The correlation coefficient r will be between -1 and 1. If it is closer to -1 or 1, it is a strong correlation. If it is closer to 0, it is a weak correlation. For example. -0.6 is closer to -1 than it is to 0, so it is a strong negative correlation. You can see that r here is -0.8566, which is strong negative.
Step 7: Lastly, you need to make the equation. It will be in the form y = mx + b. If you look under "parameters", there will be a value for m and b. Plug that in to the equation. Check to see if you need to round.
Step 8: To graph the scatterplots, you can use the graph and the points that desmos plotted as a reference. Good luck!
I hope I did it right, we just finished this at school and I got 100% on the test. Comment with any questions. Best of luck! - brainpop72

Two trains, Train A and Train B, weigh a total of 379 tons. Train A is heavier than Train B. The difference of their weights is 255 tons. What is the weight of each train?
Answer: A = 317
B = 61
Step-by-step explanation:
The following equation can be gotten from the question given. This will be:
A + B = 379 ........ i
A - B = 255 ........ ii
From equation i, make A the subject of the formula
A = 379 - B ...... iii
Put the value of A in iii into equation ii
A - B = 255
(379 - B) - B = 255
379 - B - B = 255
379 - 2B = 255
2B = 379-255
2B = 124
B = 124/2
B = 62 tons
Since A + B = 379
A + 62 = 379
A = 379 - 62
A = 317 tons

How long does it need to keep $600 in an account that pays 2.75% annual simple interest to earn $264?
Answer:
16 years
Step-by-step explanation:
Principal amount (P) = $600
Rate of interest (R) = 2.75%
Simple interest (S.I.) = $264
Let t denotes time period.
[tex]S.I.=\frac{PRT}{100}[/tex]
[tex]264=\frac{600(2.75)t}{100} \\\\t=\frac{264(100)}{600(2.75)}[/tex]
[tex]t=16[/tex] years.
Therefore,
interest of $264 will be earned in 16 years.

Which of the following is a solution to the equation:
-4x + 8y = 4
x = -3, y = -2
O x = 2, y = 3
O x = 2, y = 2
O x = 3, y = 2 soemone tell me which one-
Answer:
It's the last one where x=3 and y=2
Explanation:
Replace x and y with 3 and 2. It then becomes
-4(3) + 8(2) = 4
Solve. -4 × 3 is -12 since a positive times a negative equals a negative. 8 × 2 is 16. Bring down the 4.
-12 + 16 = 4
When solving something like this and you don't know what to do or how to solve it, you can subtract the smaller number from the larger number and then whether the sum is a negative or positive depends on the largest number. So here, 16 is the largest, so the sum will be positive. And 16-12 is 4, so the final answer is positive 4. You can also look at a number line and start from -12 and then add 16 and see which number you end at after adding 16.
In 2011, a professional climber scaled the outside of the Burj Khalifa, making it all the way to 828 meters (the highest point on which a person can stand) in 6 hours.
Answer:
276 meters in the first 2 hours
Step-by-step explanation:
Given that,
Professional climbers climb 828 meters in 6 hours.
Let us assume we need to find how far did they climb in the first 2 hours.
6 hours = 828 m
⇒ 1 hour = 138 m
So, in 2 hours,
2 hours = 138 × 2 m
= 276 m
So, the climber climb 276 meters in the first 2 hours

Tell whether the equation has one, zero, or infinitely many solutions.9(x − 3) + 15 = 9x − 11.
Answer:
Zero solutions; there are no variables and thus there are no solutions
Step-by-step explanation:
We start out with the equation 9 (x - 3) + 15 = 9x - 11
Which simplifies to 9x - 27 + 15 = 9x - 11
The 9x terms cancel each other out, and we're left with 15 - 27 = -11
And we end up with -12 = -11, which is not true.
This tells us that the equation has zero solutions, because no matter what value we substitute for x, the equation will not be true.
Answer:
No solution
Step-by-step explanation:
9(x-3)+15= 9x-11
9x-27+15=9x-11
-15 on both sides
9x-27=9x-26
add 26 on both sides
9x -1=9x
add 1 on both sides
9x=9x+1
divide 9 on both sides
x=x+1/9
No solution
A boat traveled 150 miles downstream (with the current) and back (against the current). The trip downstream took 10 hours. The trip back took 30 hours. What is the speed of the boat (b) in still water? What is the speed of the current (c)?
Answer:
b= 10 miles/hr and c= 5 miles/hr
Step-by-step explanation:
Let it's downstream and upstream speed be d and u respectively
also speed of the boat be b and speed of stream be c.
as per question d = 150/10= 15 miles/hr
and, u= 150/30= 5 miles/hr
also we know d= b+c = 15.....i and u = b-c= 5....ii
solving i and ii we get b= 10 miles/hr and c= 5 miles/hr
