What is the approximate area of the shaded portion of the diagram? (Use 3.14 as an estimate for pi.)
Answers
Answer:
218
Step-by-step explanation:
first find the area of the circle-
[tex]A=\pi r^{2} \\A=\pi 10^{2} \\A=100\pi \\A=314[/tex]
to find the area of the triangle, we need the base and the height. The base we know is 16, since we don't know the height yet, use the Pythagorean theorem to find the height. One leg is 16 the hypotenuse is 20 (2* the radius).
[tex]a^{2} +b^{2} =c^{2} \\a^{2} +16^{2} =20^{2} \\a^{2} +256=400\\a^{2} =144\\a=12[/tex]
Now I know the height is 12. Find the area of the triangle
[tex]A=\frac{1}{2} bh\\A=\frac{1}{2} (16)(20)\\A=96[/tex]
subtract the area of the triangle from the area of the circle
314-96=218

Mean =
Median =
Mode =
Range =
Answers
Answer:
mean: 7
median = 8
mode = 9
range=7
Step-by-step explanation:
(3+4+7+9+9+10)/6 =7 so thast is mean
the middle number but there is none so between 7 and 9 is 8 so that is the median
mode is the number the appears the most in a data set so that is 9
range is literally the range so 3 to 10 is a range of 7
Answer:
mean=7
mode=9
median=8
range=7

Answers
Answer:
[tex]x=12.07[/tex]
Step-by-step explanation:
From the question we are told that:
Mean [tex]\=x =12cm[/tex]
Standard deviation [tex]\sigma=0.04[/tex]
Significance level [tex]\alpha=5\%=0.05[/tex]
Therefore
Confidence level [tex]95\%=0.95[/tex]
From table [tex]P(z<1.645)=0.95[/tex]
Generally the equation for Z-score is mathematically given by
[tex]z=\frac{x-\mu}{\sigma}[/tex]
[tex]x=z\sigma+\mu[/tex]

A roulette wheel has 383838 slots, of which 181818 are red, 181818 are black, and 222 are green. In each round of the game, a ball is tossed in the spinning wheel and lands in a random slot. Suppose we watch 777 rounds of this game, and let RRR represent the number of rounds where the ball lands in a red slot.
Answers
Answer:
Of the 777 rounds of the game in about 368 the ball will land in a red slot.
Step-by-step explanation:
Since a roulette wheel has 383838 slots, of which 181818 are red, 181818 are black, and 222 are green, and in each round of the game, a ball is tossed in the spinning wheel and lands in a random slot, supposing we watch 777 rounds of this game, to determine the approximate number of rounds where the ball lands in a red slot, the following calculation must be performed:
383838 = 100
181818 = X
181818 x 100/383838 = X
18,181,800 / 383838 = X
47.3684 = X
100 = 777
47.3684 = X
47.3684 x 777/100 = X
36,805.24 / 100 = X
368.05 = X
Therefore, of the 777 rounds of the game in about 368 the ball will land in a red slot.

If P=(3,1) and Q=(-3,-7), find the
midpoint of segment PQ.
Answers
Answer: ( 0 , -3 )
Step-by-step explanation:
Correct on acellus
The point (0, -3) that lies exactly halfway between P(3, 1) and Q(-3, -7) on the line segment connecting them.
To find the midpoint of segment PQ, we can use the midpoint formula. The midpoint formula states that the coordinates of the midpoint (M) between two points, P(x₁, y₁) and Q(x₂, y₂), are given by the average of the corresponding x-coordinates and the average of the corresponding y-coordinates.
For segment PQ, we have the points P(3, 1) and Q(-3, -7). Applying the midpoint formula:
x-coordinate of the midpoint = (x₁ + x₂) / 2 = (3 + (-3)) / 2 = 0 / 2 = 0
y-coordinate of the midpoint = (y₁ + y₂) / 2 = (1 + (-7)) / 2 = -6 / 2 = -3
Therefore, the midpoint of segment PQ is (0, -3).
