Answer:
The hiker's elevation after 145 minutes will be 1958 meters.
Step-by-step explanation:
The equation of the trend line of the scatter plot showing a hiker's elevation is y = 8.77x + 686 .......... (1), where x is in minutes (say) and y is in meters (say).
Now, we have to predict the hiker's elevation after 145 minutes.
So, from equation (1) we get, y = 8.77 × 145 + 686 = 1957.65 ≈ 1958 meters. (Answer)
Answer:
8.090169944 or rounded 8.1
Step-by-step explanation:
Use SOH CAH TOA
Look at x and where it is and what you have.
First thing is to get an angle to use, 36, then to set up your equation.
___(36)=___
Figure out what you have.
You have the hypotonouse, 10, and need the adjacent,x, so you use the equation that involves H for hypotonouse and A for adjacent.
You set up your equation using COS, as you are using CAH.
Cos(36)=x/10
X is over ten sure to CAH C-cos A-adjacent and H-hypotonouse
Switch it around to make it equal to x
10*Cos(36)=x
You input it into your calculator. [10] [COS] [36] [ENTER] and you get the answer.
Round however is needed.
Answer:
so from looking at this we can see there is
0=5
1=5
2=3
3=2
4=4
5=1
6=2
7=2
8=1
9=1
now we have to add them up
5+6+16+5+12+14+8+9=75
and now we have to add up the total plots on the chart
5+5+3+2+4+1+2+2+1+1=26
now we divide
75 divided by 26=2.88461538462
so 2.9 is the mean
now we add up the number from least to greatest
0,0,0,0,0,1,1,1,1,1,2,2,2,4,4,4,4,5,6,6,7,7,8,9
so the medien is 4
Hope This Helps!!!
Answer:
85%
Step-by-step explanation:
We have 30, 35, and 20.
Your question is asking what the total percent is. Since these percents are all on only a single item, we can just add them together.
30 + 30 = 60
60 + 25 = 85
There we go! 85%

Your Welcome, and thanks in advance.
ANSWER
C) Triangle
EXPLANATION
Solving a triangle is the process of calculating unknown side lengths or angle measures of a triangle if certain of the side lengths and/or angle measures are known.
We use the sine rule and cosine rule to find the missing sides and angles.
If the triangle has a right angle, then this is a special case, where we can use the trigonometric ratios and the Pythagoras theorem to find the unknown angles and sides.
