Answer:
x = 9
Step-by-step explanation:
m<K = 71°
arc JL = 16x - 2
m<k = ½(arc JL) => inscribed angles theorem
Substitute
71 = ½(16x - 2)
Multiply both sides by 2
71*2 = 16x - 2
142 = 16x - 2
Add 2 to both sides
142 + 2 = 16x - 2 + 2
144 = 16x
Divide both sides by 16
144/16 = 16x/16
9 = x
x = 9

Answer:
Solution given:
Area of parking space [parallelogram]=290ft²
base*height=290
base=290/29
base:10ft
Area of rectangular dimensions=11*7.4=81.4ft²
yes
The truck can not fit in the space because the length and breadth is less than that of the parallelogram parking area.
Area of truck bid 81.4ft².
I mainly need #2 but if you know any of them please let me know
Answer:
1) 88 cm²
2) 34.137 cm²
3) 11.57 cm²
4) 195.938 cm²
Step-by-step explanation:
1) 6x12=72
4x4=16
72+16=88
2) 1/2x2x4x5=20
1/2π3²=14.137
20+14.137=34.137
3) 5x2=10
1/2π1²=1.57
10+1.57=11.57
4) 3x14=42
π7²=153.938
42+153.938=195.938

A sociologist develops a test to measure attitudes towards public transportation, and 27 randomly selected subjects are given the test. Their mean score is 76.2 and their standard deviation is 21.4. Find the Margin of Error (E) for the 95% confidence interval for the mean score of all such subjects.
Answer:
The margin of error for the 95% confidence interval for the mean score of all such subjects is of 8.45.
Step-by-step explanation:
We have the standard deviation for the sample, which means that the t-distribution is used to solve this question.
The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So
df = 27 - 1 = 26
95% confidence interval
Now, we have to find a value of T, which is found looking at the t table, with 26 degrees of freedom(y-axis) and a confidence level of [tex]1 - \frac{1 - 0.95}{2} = 0.975[/tex]. So we have T = 2.0518
The margin of error is:
[tex]M = T\frac{s}{\sqrt{n}}[/tex]
In which s is the standard deviation of the sample and n is the size of the sample.
In this question:
[tex]n = 27, s = 21.4[/tex]. So
[tex]M = 2.0518\frac{21.4}{\sqrt{27}}[/tex]
[tex]M = 8.45[/tex]
The margin of error for the 95% confidence interval for the mean score of all such subjects is of 8.45.

Answer nyo po to...Ang hirap(;-;)....pls. Lang po
The answer goes here,
a) We have to tell the time and day which simone has to tell her sister, for picking her up from airport.
b) We have given the day (monday), time(7:00 pm) and total time to reach the destination(18 hours).
c) No such formula will be used here, we will just use our mental ability to solve this question.
d) She will leave at 7:00 pm, day has 24 hours. So, she will be in the flight on monday:
= 24 - (12 + 7) ----------- [12 here means the time of rest of the day,(morning to noon)]
= 24 - 19
= 5 hours
So, she will complete 5 hours of her destination on monday,now the time left is:
= 18 - 5
= 13
= (12 + 1 )hours
So, on tuesday, she will be in the flight for 12 hours (noon) and then on 1:00 pm she will reach the airport, as she needs and extra hour to plane so, the final time is 1:30 pm. And finally, the time she should tell her sister is 1.30 pm.

What is the explicit rule for the geometric sequence? 25.5, 5.1, 1.02, 0.204, ... an=25.5(15)n an=25.5(15)n−1 an=25.5(15)n+1 an=25.5(15)n+2
Given:
The geometric sequence is:
25.5, 5.1, 1.02, 0.204, ...
To find:
The explicit rule for the given geometric sequence.
Solution:
We have,
25.5, 5.1, 1.02, 0.204, ...
Here, the first term is 25.5 and the common ratio is:
[tex]r=\dfrac{a_2}{a_1}[/tex]
[tex]r=\dfrac{5.1}{25.5}[/tex]
[tex]r=\dfrac{1}{5}[/tex]
The explicit rule for a geometric sequence is:
[tex]a_n=ar^{n-1}[/tex]
Where, a is the first term and r is the common ratio.
Putting [tex]a=25.5,\ r=\dfrac{1}{5}[/tex] in the above formula, we get
[tex]a_n=25.5(\dfrac{1}{5})^{n-1}[/tex]
Therefore, the correct option is B.

Write the equation of the line in slope-intercept form.
Answer:
y = 50x + 40
Step-by-step explanation:
2 points on the graph:
(0, 40) and (2, 140)
Slope:
m=(y2-y1)/(x2-x1)
m=(140 - 40)/(2 - 0)
m=(100)/2
m= 50
Slope-intercept:
y - y1 = m(x - x1)
y - 40 = 50(x - 0)
y - 40 = 50x
y = 50x + 40
Use the graph of the logarithmic function f(x) to answer the question.
