1. I can't see the first one very well.
2. Find the area of each triangle by doing 1/2 * base * height. This should give you [tex]40m^{2}[/tex]
3. The area of a trapezium is [tex]\frac{1}{2} (a+b)h[/tex] where a is the top edge, b is the bottom edge and h is the height.
We can work out the bottom edge using pythagoras - split the trapezium into 2 triangles on each side and a rectangle in the middle. This gives you the length of the bottom edge which is 2 + 2 + 2 = 6'
Work out the area by doing 1/2(2+6)4 = 16' squared.
4.Split this shape into a triangle and rectangle. We know the right hand edge of the triangle= 9-4 = 5'.
To find the bottom edge of the triangle, use tanθ=opposite/adjacent line. Therefore tan45=bottom edge of triangle/5'. tan 45=1 therefore bottom edge = 5'.
The bottom edge of triangle gives us the height; use 1/2(a+b)h to work out the area of the trapezium. 1/2(4+9)5 = 32.5' squared

A sports equipment researcher investigated how different types of wood used to make baseball bats might affect batting. The researcher selected a sample of 80 batters from summer baseball leagues and randomly assigned the batters to one of two groups: the ash bat group or the maple bat group. The mean number of hits for each group was recorded at the end of the season, and the difference in the sample means was calculated. Which of the following is the appropriate inference procedure for analyzing the results of the investigation?
A. A one-sample t-interval for a population mean
B. A one-sample t-interval for a sample mean
C. A matched pairs t-interval for a mean difference
D. A two-sample t-interval for a difference between sample means
E. A two-sample t-interval for a difference between population means
Answers
Answer:
E
A two-sample t -interval for a difference between population means
Step-by-step explanation:
i just took the test
The appropriate inference procedure for analyzing the results of the investigation is option E. A two-sample t-interval for a difference between population means
Analysis the results of the investigation:Since the researcher selected a sample of 80 batters from summer baseball leagues and batters assigned to one of the two groups. So this means that the researcher is interested to know whether the mean no of hits should be different for two groups and both groups are independent to each other.
Therefore, The appropriate inference procedure for analyzing the results of the investigation is option E. A two-sample t-interval for a difference between population means

1. The more seats an airline can put in an airplane, the more money it will make. However, if seats are too narrow, passengers will be angry and uncomfortable. An airline might first consider the average woman's hip breadth when designing seats. Why would the airline use women instead of men when determining the maximum width of an airline seat?
Answers
Answer:
Airlines would use women instead of men because women usually have wider hips compared to the average men. So if they give enough room for the average women, then there will be enough room for the average man.

Given the equation y = 12x − 25, describe a real-life context that could be modeled by the equation and describe the meaning of the coefficient, variable, and constant term expressed in the equation.
Answers
Answer:
Kindly check explanation
Step-by-step explanation:
Given the equation :
y = 12x − 25
The initial depth of groundwater being held by a storage tank which extends downward below the ground surface is - 25. The rate of change in depth the groundwater per unit of Rainfall is 12. Hence, a linear model which could model the depth of water in the tank in the described scenario is ;
y = 12x − 25
The rate of change in depth of ground water, y per unit change in number of Rainfall, x gives the slope Coefficient, which equals 12
The intercept value, which is the initial depth of groundwater before, it started raining is - 25

Rebecca has been planting young trees in her garden. The maple tree that is 10 centimeters tall
is growing 2 centimeters per month, whereas the oak tree that is 15 centimeters tall is
growing 1 centimeter per month. In a few months, the two trees will be the same height. How
many months will this take and what will that height be?
Answers
Answer:
It will take 5 months and that height will be 20cm.
Step-by-step explanation:
Let the height of the tree be h cm and the number of months be m.
Maple tree
Initial height= 10cm
Total height= 10cm +2(number of months)
h= 2m +10 -----(1)
Oak tree
Initial height= 15cm
Total height= 15cm +1(number of months)
h= m +15 -----(2)
When the height of the two trees are the same,
2m +10= m +15
Solve for m:
2m -m= 15 -10
m= 5
Substitute m=5 into either equation 1 or 2 to obtain the height.
When m=5,
h= 5 +15
h= 20
