Answer:
a) 6.1 feet
b) 12.6 feet
Step-by-step explanation:
Using trigonometric ratios we know that:
[tex]sin = \frac{opp}{hyp}\\cos = \frac{adj}{hyp}\\tan = \frac {opp}{adj}[/tex]
AKA SohCahToa.
To find the height, we will use sine.
[tex]sin(26^o)= \frac{x}{14}\\14*sin(26^o)=\frac{x}{14}*14\\14sin(26^o)=x\\x=6.14[/tex]
To find the length we will use cosine.
[tex]cos(26^o) = \frac{x}{14}\\14*cos(26^o)=\frac{x}{14}*14\\14cos(26^o)=x\\x=12.6[/tex]

According to a recent survey, 81 percent of adults in a certain state have graduated from high school. If 15 adults from the state are selected at random, what is the probability that 5 of them have not graduated from high school?
Answer:
0.090401
Step-by-step explanation:
Given that:
Probability of graduate = 81% = 0.81
P( not graduate) = p = (1 - 0.81) = 0.19
1 - p = 0.81
Using binomial distribution :
P(x = x) = nCx * p^x * 1-p^(n-x)
n = 15 ; x =5
P(x = 5) = 15C5 * 0.19^5 * 0.81^(15 - 5)
P(x = 5) = 15C5 * 0.19^5 * 0.81^10
P(x = 5) = 3003 * 0.0002476099 * 0.12157665459056928801
P(x = 5) = 0.090401
Answer:
D: (15/5) (0.19)^5 (0.81)^10

Answer:
3, 0, 2, -2
Step-by-step explanation:
Put x=2 into each equation and solve for y.
2 + y = 5
y = 5 -2
y = 3
3x +2y = 6
3·2 +2y = 6
2y = 6 -6 = 0
y = 0
2x +y = 6
2·2 +y = 6
y = 6 -4
y = 2
5x +3y = 4
5·2 +3y = 4
3y = 4 -10 = -6
y = -2

Step-by-step explanation:
A real-estate company appraised the market value of 36 homes in Lyttelton and found that the sample mean and standard deviation were $150,000 and $17,000 respectively. The real-estate company also appraised the market value of 45 homes in Aranui and found that the sample mean and standard deviation were $100,000 and $12,000 respectively. Calculate the 90% confidence interval estimate for the population difference in market value between the Lyttelton and Aranui areas .
Solution :
Sample size Sample mean Sample S.D.
Sample 1 [tex]$n_1=36$[/tex] [tex]$\bar{x}_1=150,000$[/tex] [tex]$s_1=17,000$[/tex]
Sample 2 [tex]$n_2=45$[/tex] [tex]$\bar{x}_2=100,000$[/tex] [tex]$s_2=12,000$[/tex]
[tex]$df = \frac{\left(\frac{s_1^2}{n_1}+\frac{s_2^2}{n_2}\right)^2}{\frac{1}{n_1-1}\left(\frac{s_1^2}{n_1}\right)^2+\frac{1}{n_2-1}\left(\frac{s_2^2}{n_2}\right)^2}$[/tex]
= 60
Therefore, significance level, α = 0.1
Critical value, t* = 1.6706
So, the margin of error, [tex]$t^*=\sqrt{\frac{s_1^2}{n_1}+\frac{s_2^2}{n_2}}$[/tex]
= 559.9896
Lower limit, [tex]$(\bar x_1-\bar x_2)-\text{(margin of error)}=44402.0104$[/tex]
Upper limit, [tex]$(\bar x_1-\bar x_2)+\text{(margin of error)}=55597.9896$[/tex]
Therefore 90% C.I. is (44402.0104, 55597.9896) or [tex]$44402.0104 < \mu_1 - \mu_2 < 55597.9896$[/tex]

We want to find the zeros of this polynomial:
p(2) = (2x - 1)(x+3)(x + 1)(x - 2)
Plot all the zeros (x-intercepts) of the polynomial in the interactive graph.
Answer:
How do you find the zeros of a polynomial graphically?
Step-by-step explanation:
If we graph this polynomial as y = p(x), then you can see that these are the values of x where y = 0. In other words, they are the x-intercepts of the graph. The zeros of a polynomial can be found by finding where the graph of the polynomial crosses or touches the x-axis.

Sam is interested in buying a TV. At Walmart, the TV is regularly prices at $599.99 and is on sale for 20% off the regular price. At Best Buy, the same TV is regularly prices at $899.99 and is on sale for 30%off the regular price.
What is the difference in the sale price of the TV between these two stores?
Show your work.
Answer:
If 30% of 599.99 is 197.99 and 30% of 899.99 is 269.99 then you subtract 269.99-197.99= $72

It takes Zion three times as long to paint a room as it does Sanjay. How long does it take each person by
himself if they can paint the room together in 30 minutes?
Answer:
It takes Sanjay 40 minutes and Zion 120 minutes
Step-by-step explanation:
If it takes Sanjay x minutes, it takes Sanjay 3 * x = 3x minutes
Painting together, they spent 30 minutes
1/x + 1/3x = 1/30
4/3x = 1/30
4 * 30 = 3x * 1
120 = 3x
x = 120/3
x = 40 minutes
3x = 3 * 40 = 120 minutes
Help please ASAP 10 points
Answer:
The answer is D
Step-by-step explanation:
Because parallel means "(of lines, planes, surfaces, or objects) side by side and having the same distance continuously between them." - Google Dictionary
This means that if you draw two lines next to each other and no matter how far they go on, they will never meet.
You can remember this by looking at the two L's in 'parallel' and seeing how they will never meet - because they are parallel to each other

Betsy buys three lamps and two end tables and pays $520. Her friend Tina buys two lamps
and RETURNS an end table and only pays $20. What do the lamps and end tables cost?
9514 1404 393
Answer:
lamp: $80end table: $140Step-by-step explanation:
If we let x and y represent the costs of a lamp and end table, respectively, the two purchases can be written as ...
3x +2y = 520
2x -y = 20
__
These equations can be solved many ways. If we use "elimination", we can add twice the second equation to the first to eliminate y:
(3x +2y) +2(2x -y) = (520) +2(20)
7x = 560 . . . . simplify
x = 80 . . . . . . divide by 7
y = 2x -20 = 2(80) -20 = 140
The cost of a lamp is $80; the cost of an end table is $140.
