help please ! if false can you explain or show why
Answer:
False
Step-by-step explanation:
The sum of angles of a parallelogram is equal to 180°. So,
8x+3y+2x+(7x+18)=180
or
17x+3y = 180-18
17x+3y = 162
Put x = 44 and y = 18 in the above expression.
So,
17(44)+3(18) = 748+54
= 802
≠ 162
Hence, the given statement is false.
Select the correct answer. A farmers' group conducted an experiment to determine which fertilizer is better for plant growth. One fertilizer contains a urea supplement, while the other does not contain the urea supplement. For the experiment, they randomly selected 20 plants of the same species growing in their area. The farmers tested the urea-enhanced fertilizer on 10 plants and the non-urea fertilizer on the other 10 plants. After three months, they reported their findings as shown.
Answer:
Step-by-step explanation:
at the bottom it has a key and the key shows blue that had the urea supplement and green with out. the graph has a higher amount of growth for the plants with the urea supplement and green with about half the growth.
so you could say something like this: over the course of three months the plants with the urea supplement had almost double the amount of growth the plants without the urea supplement did, over all the the urea increased the amount of growth the plants had over the 3 month time span. :)
The conclusion from the farmer's data can be made is the fertilizer with urea supplement is more effective than the fertilizer without it.
What is histogram?A histogram is the way of representation of data which is used to show the frequency distribution using the rectangle similar to bar graph.

For the experiment, they randomly selected 20 plants of the same species growing in their area. The farmers tested the urea-enhanced fertilizer on 10 plants and the non-urea fertilizer on the other 10 plants.
After three months, they reported their findings as shown. Let's understand what happen in each month,
In first month, 4 number of plants with above average growth with urea supplement, while only 2 plant shown this growth when urea is not supplied.In second month, 7 number of plants with above average growth with urea supplement, while only 4 plant shown this growth when urea is not supplied.In third month, 5 number of plants with above average growth with urea supplement, while only 3 plant shown this growth when urea is not supplied.Thus, the conclusion from the farmer's data can be made is the fertilizer with urea supplement is more effective than the fertilizer without it.

A hockey player earns 2 million in 2015 during the next 10 years to earnings increase 5% each year write an explanation growth model giving the earnings Y in millions of dollars T years after 2015 write the base of the model as a decimal
Answer:
[tex]Y(T) = 2(1.05)^T[/tex]
Step-by-step explanation:
The player's salary, in millions of dollars, t years after 2015, is given by an equation in the following format:
[tex]Y(T) = Y(0)(1+r)^T[/tex]
In which Y(0) is his initial salary and r is the growth rate, as a decimal.
A hockey player earns 2 million in 2015 during the next 10 years to earnings increase 5%
This means, respectively, that:
[tex]Y(0) = 2, r = 0.05[/tex]
So
[tex]Y(T) = Y(0)(1+r)^T[/tex]
[tex]Y(T) = 2(1+0.05)^T[/tex]
[tex]Y(T) = 2(1.05)^T[/tex]

Write the coordinates as decimals or integers.
Answer:
In decimal 0.428571428
Step-by-step explanation:
The slope = (y2 - y1)/(x2 - x1) y2 = 16, y1 = 19x2=2 and x1=9
The slope = (16 - 19)/(2 -9)
The slope = (-3)/(-7)
The slope = 0.428571428
So in decimal form the coordinates are going to be written as 0.428571428
Slope is the steepness of a line, it is the difference between the y coordinates divided by the difference in x coordinates.

Quadrant II and III
Step-by-step explanation:
Given
Point E
[tex]x < 0[/tex] i.e. negative x
and
[tex]y \ne 0[/tex]
Required: Determine the possible quadrant(s) of E
[tex]y \ne 0[/tex]. means that point E belongs to at least 1 quadrant. So, x-axis and y-axis are ruled out
Solving further:
[tex]x < 0[/tex]
The two quadrants where the x coordinates is negative are II and III.
Hence, point E belongs to quadrants II or quadrants III

Answer:
The total surface area of the shape is 376 square inches.
Bonus: the volume is 240 cubic inches.
Step-by-step explanation:
I'm not going to draw this for you, but to get the area, you just need to add up the area of the 6 rectangles.
First though, you need to know what they are. This is easier than it may seem though. You just need to remember that this will be folded into a rectangular box. You are given three side lengths, which is all that is needed for a box.
That is to say, you're given the width, height and length of this box. It's 10x8x6 inches.
so if you take every possible pairing of those numbers:
10x8
10x6
8x6
you have the area of all of the shapes. The only catch is that there are two of each size. Front and back are the same size, left and right are, and so are top and bottom.
So the total area of the shape is:
(front and back) + (left and right) + (top and bottom)
= (2 × 10 × 8) + (2 × 10 × 6) + (2 × 8 × 6)
= 160 + 120 + 96
= 376
Or rather, 376 square inches.
Bonus: the volume is much easier, being just 10 × 8 × 6, or 240 cubic inches.
