You are hiking in Marin, and stop to stand on the edge of a cliff overlooking the Pacific ocean. You see a sailboat down in the water below you. The angle of depression to the sailboat is 28◦ . A quick tells you that the cliff you’re standing on is 150ft. How far away from the boat are you, in feet, rounded to one decimal place?(30pts)

The ages of two groups of karate students are shown in the following dot plots:
A dot plot shows Age in years on the horizontal axis. For Group A, there are 2 dots on 4, 5 dots on 5, 3 dots on 7, 4 dots on 8, 2 dots on 9, 2 dots on 11, and 1 dot on 14. For Group B, there is 1 dot on 7, 2 dots on 8, 1 dot on 9, 1 dot on 11, 1 dot on 16, 2 dots on 19, 2 dots on 20, 2 dots on 21, and 1 dot on 26.
The mean absolute deviation (MAD) for group A is 2.07 and the MAD for group B is 5.51. Which of the following observations can be made using these data?
Group A has greater variability in the data.
Group A has less variability in the data.
Group B has a lower range.
Group B has a lower mean.
Answer:
Group A has greater variability in the data.
Step-by-step explanation:
We use elimination. Clearly, from the MAD, Group A has greater variability in the data.
So, choice 1.
The function f(x)=-\x-4/+6 is increasing
through the interval -
A. 6
C. 4
B. -00< x < 4
D. 4
:)
Answer:
Option B
Step-by-step explanation:
Given function is,
f(x) = -|x - 4| + 6
By using a graphing tool we can get the graph of the given function.
From the graph attached slope of the line drawn from [tex]x=-\infty[/tex] to [tex]x=4[/tex] is positive while slope of the line from [tex]x=4[/tex] to [tex]x=\infty[/tex] is negative.
Therefore, segment showing a positive slope will be increasing in the given interval [tex]-\infty<x<4[/tex].
Function 'f' is increasing in the interval [tex]-\infty<x<4[/tex].
Option B will be the correct option.

John brother Ricky also works part time in the summer. Ricky started working at the same time as John with a. Account balance of $227and deposit $24 each week. Writ an expression for the amount Ricky has in the bank after w week
Answer:
$227 + $24w
Step-by-step explanation:
Initial balance = $227
Amount deposited per week = $24
Amount in account after w weeks
Total amount = initial balance + total weekly deposit
Total Weekly deposit = $24 * number of weeks
Number of weeks = w
Hence,.
Total deposit = $227 + $24w

Step-by-step explanation:
to solve the equation 4+3x^2-7x=0 using the quadratic formula, what are the values of a, b, and c
a = 3
b = -7
c = 4
Explanation
what you need to know:
[tex]a {x}^{2} + bx + c = 0[/tex]
what you have:
[tex]4 + 3 {x}^{2} - 7x = 0[/tex]
so you just rearrange them from highest exponent being on the left to lowest exponent being on the right:
[tex]3 {x}^{2} - 7x + 4 = 0[/tex]
1. Find the probability of rolling a sum less than 4 or a
sum greater than 8 when a pair of dice is rolled.
=============================================================
Explanation:
Refer to the chart below. The values in red up top add to the values in blue along the left column to get the 6 by 6 grid of values inside. This represents all of the possible ways to add up values on a pair of dice. There are 6*6 = 36 outcomes.
Of those 36 outcomes, we have 13 outcomes where we roll less than a 4, or greater than 8
outcome = 1+1 = 2outcome = 1+2 = 3outcome = 2+1 = 3outcome = 3+6 = 9outcome = 4+5 = 9outcome = 5+4 = 9outcome = 6+3 = 9outcome = 4+6 = 10outcome = 5+5 = 10outcome = 6+4 = 10outcome = 5+6 = 11outcome = 6+5 = 11outcome = 6+6 = 12These 13 results are shown in green boxes in the diagram.
Since we have 13 ways to get what we want, out of 36 total, the final answer as a fraction is therefore 13/36
13/36 = 0.3611 = 36.11% approximately

Answer:
36 ft
Step-by-step explanation:
Given :
12 yards.We need to convert it into feets. We know that ,
[tex] \implies[/tex] 1 yard = 3 feet
[tex] \implies[/tex] 12 yards = 12 * 3 ft
[tex] \implies[/tex] 12 yards = 36 ft .
Hence the required answer is 36 feets .
Answer:
the formula for converting yards into feet: 1 yard is equal to 3 feet. Write out the necessary math problem or use a calculator. If you want to convert 21 yards, for example, the problem would be 21 multiplied by 3 (21 x 3). Finish the conversion.
SO,
12 yd 36.00 ft

Step-by-step explanation:
The equations with solution x = 1 and y = (-1) will intersect each other at (1,-1) .
Equation 1 :-
Say slope is 1 .→ y - (-1) = 1 ( x -1)
→ y +1 = x -1
→ x - y -2 = 0
Equation 2 :
Slope = -1→ y - (-1) = -1( x -1)
→ y +1 = -x +1
→ x + y = 0

Rewrite the expression in the form zn.
Answer:
zⁿ = z³
Step-by-step explanation:
We have the expression:
√(z/ z^⅓)
Hence
= z^½/ (z^⅓)^½
= z^½/ (z^⅙)
= z^(½ ÷⅙)
= z ^(1/2 × 6/1)
= z³
Therefore: zⁿ = z³

Answer:
x=-2
Step-by-step explanation:
1.1x +1.2x -5.4 = -10
Combine like terms
2.3x -5.4 = -10
Add 5.4 to each side
2.3x -5.4+5.4 = -10+5.4
2.3x = -4.6
Divide each side by 2.3
2.3x/2.3 = -4.6/2.3

what is the value of x
Answer:
20
Step-by-step explanation:
Those angles are the same so you can put them in an equation like this:
x + 60 = 4x
Then you subtract x from both sides to get variables on one side and constants on the other:
60 = 3x
Now divide by three to find what just x is:
20 = x

Which diagram is NOT a good model of 1/5÷6?
Answer:
The circle one
Step-by-step explanation:
What you need to do is count the number of squares or slices it has and then count how Buchanan the chunk is divided into, should be 6
==============================================================
Explanation:
Ignore the dashed smaller lines for now. The solid black vertical lines form 4 smaller equal pieces, and not 5. Each tickmark represents 1/4 and not 1/5
So if you wanted to represent a model for [tex]\frac{1}{4}\div 6[/tex], then you would use the lower left corner. However, we want that 1/4 to be 1/5 instead. So this is why the answer is the lower left corner.
Everything else is a correct model. We started dividing everything into 5 equal parts. Then we focused on one of those slices, and subdivided that slice into 6 equal parts. Imagine doing that for each slice and we should have 5*6 = 30 smaller pieces total. Hence [tex]\frac{1}{5} \div 6 = \frac{1}{5} \times \frac{1}{6} = \frac{1}{30}[/tex]
