Answer:
102.0
Step-by-step explanation:
The area of the shaded region will be 3521.14 cm². It is obtained by subtracting total area from unshaded region.
How to find area of the shaded region?
The difference between the area of the complete polygon and the area of the unshaded section inside the polygon is the shaded region's area is the area of the shaded region.
The total area of the region is;
A=πr²
A=3.14×7²
A=153.86 cm²
The area of unshaded section;
A₂=r²(α/2)
A₂=7²(150/2)
A₂=3675
The area of the shaded region is;
Area of shaded region=Total area - area of unshaded region
Area of shaded region=3675 -153.86
Area of shaded region=3521.14 cm²
Hence, the area of the shaded region will be 3521.14 cm².

14. What’s the domain and range?
Answers
Answer:
See below
Step-by-step explanation:
13) Domain: x -> {-3,-2,-1,0,1,2}, Range: f(x) -> {5}
14) Notice how x can't be -4 as that will make the denominator 0. Therefore, your domain is (-∞,-4)U(-4,∞) and your range is [0,∞) since 0 is the lowest possible real y-value that satisfies the equation (recall that if y<0, you are unable to find the real square root of a real number)

25 miles per hour faster for a total of 4.25 hours. What is the total distance
that the plane travels?
Answers
Answer:
Step-by-step explanation:
Olivia, use the dirt formula d = rt
distance = rate * time
x = rate * 4.5
x = (rate+25) *4.25
set them equal
rate)*4.5 = (rate+25) *4.25
4.5rate = 4.25 rate + 106.25
4.5rate- 4.25 rate = 106.25
0.25rate = 106.25
rate = 425
4.5(425) = 1912.5
check it
4.25(425+25) = 1912.5 yes it checks , that's right :)

quadrilateral ABCD is inscribed in circle O if the measure of arc AB is 104 and the measure of arc BC is 88 what is the measure of ABC?
84
96
168
192
Answers
Answer:
84degrees
Step-by-step explanation:
First we need to get the measure of arcCA;
arcCA + arcAB+arcBC = 360
arcCA + 104 + 88 = 360
arcCA + 192 = 360
arcCA = 360 - 192
arc CA = 168degrees
Also since m<ABC = 1/2 arcCA
m<ABC = 1/2 * 168
m<ABC = 84degrees
Hence the measure m<ABC is 84degrees
Answer:
84°

Cual es la magnitud de la aceleración angular de una llanta de un automóvil que adquiere una velocidad angular de 350 rad/s en 2 segundos?
Answers
Respuesta:
175 rad / s²
Explicación paso a paso:
Dado que :
Velocidad angular final = 350 rad / s
Tiempo empleado = 2 segundos
La aceleración angular, a =?
Recordar ; la aceleración angular es igual a la carga en velocidad angular con el tiempo
(velocidad final - Velocidad inicial) / tiempo empleado
Velocidad inicial = 0 rad / s
Aceleración angular = (350 - 0) / 2 = 350/2
= 175 rad / s²

Suppose that H 0 is actually true. Which situation below would have the lowest probability of a Type I error?

The situation that would have the lowest probability of a Type I error is the one with the smallest significance level (α).
What is hypothesis testing?Hypothesis testing is a statistical method that is used to make decisions about a population based on a sample of data.
It involves testing a null hypothesis (H0) against an alternative hypothesis (Ha) using statistical techniques.
We have,
In hypothesis testing,
A Type I error occurs when we reject the null hypothesis (H0) when it is actually true.
The probability of a Type I error is denoted by the symbol alpha (α) and is usually set to a small value, such as 0.05 or 0.01.
Now,
To minimize the probability of a Type I error, we want to choose a significance level (α) that is small.
This means that we are willing to accept a lower probability of detecting a difference when one actually exists (i.e., a higher probability of a Type II error).
For example,
If we set α = 0.01, we are saying that we are willing to accept only a 1% chance of incorrectly rejecting the null hypothesis (H0) when it is actually true. This would result in a very small probability of a Type I error.
Therefore,
The situation that would have the lowest probability of a Type I error is the one with the smallest significance level (α).
