Answer:
14200
Step-by-step explanation:
The formula of amount be , A = P + SI = P + {(P × R × T)/100} = 14200
What is the Si formula?
Simple interest exists estimated with the following formula:
S.I. = (P × R × T)/100,
where P = Principal, R = Rate of Interest in % per annum, and T = Time, usually computed as the number of years.
The rate of interest is in percentage r% and exists to be noted as r/100.
Given: P = 6000, T = 10 and R = 12
S.I. = (P × R × T)/100
[tex]$SI = (6000*12*10)/100[/tex]
SI = 7200
A = P + SI
A = 6000 + 7200
A = 14200
Therefore, the amount = 14200.

Answer:
382.50
Step-by-step explanation:
Area of the Shaded region = Area of the larger triangle - Area of the smaller triangle;
Let's find the area of the large triangle first;
A = 1/2(base) * (height)
A = 1/2(33) * (33)
A = 16.5 * 33
A = 544.5
Now let's find the area of the small triangle;
A = 1/2(base) * (height)
A = 1/2(18) * (18)
A = 9 * 18
A = 162
Area of the shaded region;
=> 544.5 - 162
=> 382.5 (if rounded to the nearest hundredths, 382.50)
Hope this helps!

Step-by-step explanation:
Each number 1 2 3 etc are counting by 5's. 11, five times is 55. It cannot be D because the shorter needle determines the hour and the longer one is on 11. It can't be A because counting by 5 starts with 1 not 12 it rotates clockwise not anti-clockwise. It can't be C because for it to be 50, it would need to be on the 10 not on 11.
In a (Gallup poll, 26.6% of 5000 people reported a Body Mass Index (BMl) greater than 30, which is classified as obese. The 5000 people polled are a random sample of adults, aged 18 and older, from the United States population. Choose the correct interpretation for the 98% confidence interval for the proportion of the population who arc obese? A. The proportion of adults in the United States, aged 18 or older, who are obese is between 0.2515 and 0.2805. B. We are 98% confident the proportion of adults polled who are obese is between 0.2515 and 0.2805. C. In 98% of all samples, the proportion of adults polled who are obese will be between 0.2515 and 0.2805. D. We are 98% confident that the proportion of adults in the United States, aged 18 or older, who are obese is between 0.2515 and 0.2805.
Answer:
D. We are 98% confident that the proportion of adults in the United States, aged 18 or older, who are obese is between 0.2515 and 0.2805.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which
z is the z-score that has a p-value of [tex]1 - \frac{\alpha}{2}[/tex].
26.6% of 5000 people reported a Body Mass Index (BMl) greater than 30
This means that [tex]\pi = 0.266, n = 5000[/tex]
98% confidence level
So [tex]\alpha = 0.02[/tex], z is the value of Z that has a p-value of [tex]1 - \frac{0.02}{2} = 0.99[/tex], so [tex]Z = 2.327[/tex].
The lower limit of this interval is:
[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.266 - 2.327\sqrt{\frac{0.266*0.734}{5000}} = 0.2515[/tex]
The upper limit of this interval is:
[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.266 + 2.327\sqrt{\frac{0.266*0.734}{5000}} = 0.2805[/tex]
The correct interpreation is that we are 98% confident that the proportion of adults in the United States, aged 18 or older, who are obese is between 0.2515 and 0.2805, which means that the correct answer is given by option D.

If m∠3 = 153°, then what are the measures of the remaining angles?
a.) m∠1 = 27°, m∠2 = 27°, m∠4 = 153°
b.) m∠1 = 27°, m∠2 = 153°, m∠4 = 153°
c.) m∠1 = 153°, m∠2 = 153°, m∠4 = 153°
d.) m∠1 = 153°, m∠2 = 27°, m∠4 = 27°
Answer:
it would be d because 2 and 4 would only make sense to be 27° and 1 to be 153
Answer:
<1 = <3 = 153
<2 = <4 = 27
Step-by-step explanation:
Angle 1 and Angle 3 are equal since they are vertical angles
<1 = <3 = 153
<1 and <2 make a straight line so they add to 180
153 + <2 = 180
<2 = 180-153
<2 = 27
<2 and <4 are equal since they are vertical angles
<2 = <4 = 27

for the equation y= x + 5, find the value of y when
(a)x= -2,
(b)x=0,
(c)x=2,
(d)x=4.
Answer:
a) 3 b) 5 c) 7 d) 9
Step-by-step explanation:
For this, you want to replace x in the equation y=x+5 with each of the values listed.
For the first one, -2, the equation becomes y=-2+5, which is solved to y=3.
For the second one, 0, the equation becomes y=0+5, which is solved to y=5.
For the third one, 2, the equation becomes y=2+5, which is solved to y=7.
For the last one, 4, the equation becomes y=4+5, which is solved to y=9.

The figure shows two parallel lines cut by a transversal. what is the measure in degrees of angle ABC?
Answer:
70
Step-by-step explanation:
2x and (4x-70) have the same measurements.
Set your formula up as
2x = 4x-70
2x-4x=-70
-2x=-70
x=35
Now substitute 35 in place of x
2x = 2*35 = 70
4x-70 = 4*35 - 70 = 70
A $100 MP3 player is marked up by 10% and then marked down by 10%. What is that final price?
Answer:
$99
Step-by-step explanation:
MP3 Player: $100
10% Mark up: $100/10= 10
Therefore, Mark-Up Price: $100+$10= $110
This was then Marked down by 10%.
Therefore,
10% Marked down: $110/10= $11
(We then take this away from the marked up price)
Hence, Final Price : $110-$11= $99
