Answer:
1620 degrees.
Step-by-step explanation:
In a polygon the number of sides = the number of angles.
Each external angle = 360 / 11 = 32 8/11 degrees.
Each internal angle = 180 - 32 8/11 = 147 3/11 degrees
So sum = 147 3/11 * 11
= 1617 + 3
= 1620 degrees.
Answer:
It's 1620°
Hope it helps
Step-by-step explanation:
Hint:>
( The sum of the interior angle (S),
The the sides of the polygon (n).)
Then use this formula :
S=180°(n-2)
= 180°(11-2)
= 180°(9)
= 1620°
The school Amina goes to is selling tickets to a choral performance. On the first day of ticket sales the school sold 3 senior citizen tickets and 1 child ticket for a total of $38. The school took in $52 on the second day by selling 3 senior citizen tickets and 2 child tickets. Find the price of a senior citizen ticket and the price of a child ticket.
Answer:
child = $14
senior = $8
Step-by-step explanation:
3s + c = 38
3s + 2c = 52
52 - 38 = 14
child = $14
3s + 14 = 38
3s = 24
divide by 3
senior = $8

The diameter of a semicircle is 10 meters. What is the perimeter of the semicircle, in meters? Round your answer to the nearest tenth.
Answer:
25.7 m
Step-by-step explanation:
The formula for the circumference of a circle is C = 2(pi)(r), where r is the radius, which in turn is half the diameter. Thus, the formula for the circumference is C = (d)(pi). The perimeter of a semicircle is half that, or
C = (pi)(r), which here is (3.14)(5 m) = 15.7 m. Finally, the total perimeter is the sum of this 15.7 m and the 10 m diameter of the circle:
P = 15.7 m + 10 m = 25.7 m

How to find the arc length (geometry)
Answer:
94.2
Step-by-step explanation:
Arc length is basically circumference.
Circumference formula: 2πr
All we need is the radius.
Radius = r
15 x 2 = 30 (diameter)
Then we are going to multiply by pi.
Arc length = 30π OR 94.2

coordinate point (0,b)
Slope= -6/5
Y-Intercept = 2
Point-Slope Form:
Answer:
y - 2 = -⁶/₅xStep-by-step explanation:
The point-slope form of the equation of the line passing point (x₁, y₁) and with the slope of m is: y - y₁ = m(x - x₁)
m = -⁶/₅
Y-Intercept = 2 ⇒ point (0, 2) ⇒ x₁ = 0, y₁ = 2

CNNBC recently reported that the mean annual cost of auto insurance is 958 dollars. Assume the standard deviation is 144 dollars, and that the population is normally distributed. You will use a simple random sample of 99 auto insurance policies. Note: You should carefully round any intermediate values you calculate to 4 decimal places to match wamap's approach and calculations. Find the probability that a single randomly selected policy has a mean value between 934.8 and 965.2 dollars. P(934.8 < X < 965.2) = Enter your answer as a number accurate to 4 decimal places
Probability that a single randomly selected policy has a mean value between $934.8 and $965.2 is approximately 0.5819.
To find probability we can use the properties of the normal distribution.
Given,
Mean (μ) = $958
Standard deviation (σ) = $144
Sample size (n) = 99
We want to find the probability P(934.8 < X < 965.2). X represents the mean value of a randomly selected policy.
Calculate z-score for the lower value.
z1 = (934.8 - μ) / (σ / sqrt(n))
Calculate z-score for the upper value.
z2 = (965.2 - μ) / (σ / sqrt(n))
Cumulative probability between the z-scores.
P(934.8 < X < 965.2) = P(z1 < Z < z2)
If P(Z < z1) = 0.2658. P(Z < z2) = 0.8477. The probability of interest would be.
P(934.8 < X < 965.2) = P(z1 < Z < z2) = P(Z < z2) - P(Z < z1) = 0.8477 - 0.2658 = 0.5819
Probability that a single randomly selected policy has a mean value between $934.8 and $965.2 is approximately 0.5819.
