Answer:
Angle BOC = 120°
Angle DOC = 60°
Angle ODC = 90°
Step-by-step explanation:
Triangle ABC is an equilateral triangle, therefore Angle BAC = 60°.
Now that we know Angle BAC, we can find Angle BOC: 2 × 60 = 120°
Angle DOC = ½ Angle BOC ( Radius drawn from centre to midpoint of chord, bisect the angle)
So Angle DOC = ½ (120) = 60°
Angle = 90° because D is the midpoint of chord BD and OD is a radius.

What do you mean by probability?
Probability is a way to gauge how likely something is to happen. Many things are difficult to forecast with absolute confidence. Using it, we can only make predictions about how probable an event is to happen, or its chance of happening.
By simply dividing the favorable number of possibilities by the entire number of possible outcomes, the probability of an occurrence can be determined using the probability formula.

danielle’s mistake subtract x3 - 2x2 from x2-6
Answers
we get - x³ + 3 x² - 6 after subtracting x³ - 2 x² from x² - 6.
We are given two expressions:
x³ - 2 x²
x² - 6
We need to subtract x³ - 2 x² from x² - 6
We get the expression as:
x² - 6 - (x³ - 2 x²)
Opening the brackets, we get that:
= x² - 6 - x³ + 2 x²
Combining the like terms, we get that:
= 3 x² - x³ - 6
Simplifying the expression, we get that:
= - x³ + 3 x² - 6

An analysis of variance produces ssbetween = 30, sswithin = 60, and an f-ratio with df = 2, 15. for this analysis, what is the f-ratio?
Answers
For this analysis, 4/25 is the f-ratio.
What is f- ratio?
In the psychosocial, behavioral, and health sciences, the F-ratio is frequently employed in study on quality of life. In order to compare two or more groups, it often refers to a statistic that is produced by dividing two sample variances that are supposed to come from normally distributed populations.SS between = 30
SS within = 60
Mean square of regression = 30/2 = 15
Mean square of error = 60/15 = 4
So f ratio = 15/4 = 3.75
So it's answer is D.
Solution(15)
Df between = Df total - Df within = 29-27 = 2
So it's answer is b. I.e. 2
Solution(16)
If Df = 18 and there are two independent sample than total sample size = 18+2 = 20
So it's answer is A
Solution(17)
N1=10
N2 = 15
So DF = 10+15-2 = 23
So it's answer is C. I.e. 23
Solution(18)
D = (M1-M2)/spooled = (35-31)/25 = 4/25

Graph of carbonate concentration versus time calcification rate.
At 270 umol/kg of seawater carbonate ion concentratio the approximate rate of calcification will be 20 mmol CaCO3 per m2 per day.
So it will take 1.5 days for 1 m2 of reef to accumulate 30 mmol of CaCO3
For Part G-
At 250 umol/kg of seawater carbonate ion concentratio the approximate rate of calcification will be 10 mmol CaCO3 per m2 per day.

What is the calcification rate?The rate at which corals that form reefs lay down their calcium carbonate skeleton is known as coral calcification. It serves as a gauge of coral growth, which is crucial for the sustainability of reef ecosystems.

Answers
For the car travelling with 55 miles per hour-
unit rate = 55 miles per hour.distance travelled = 275 miles.distance travelled = 825 miles.Time taken = 2 hoursWhat is distance speed relation?The distance is a actual length of a path taken by the object.
The speed is the rate at which the distance changes over time. If 'D' is the distance traveled by an object in time 'T,' the speed is equal to s = D/T. It is measured in the same units as velocity.For, the values given in the question;
1. The unit rate speed for this car is ___ miles per hour
S = D/T
S = 55 miles per hour.
Rate of speed is the same as the speed.
Thus,
The unit rate speed for this car is 55 miles per hour
2. if the car has driven 1/2 (0.5) hours, it traveled ___ miles
S = D/T
D = S×T
S = 55 miles per hour.
T = 0.5
Put the values;
D = 55×0.5
D = 275 miles.
Thus, the car travelled 275 miles.
3. if the car has driven 1 1/2 (1.5) hours, it has traveled ___ miles
S = D/T
D = S×T
S = 55 miles per hour.
Put the values;
D = 55×1.5
D = 825 miles.
Thus, the car travelled 825 miles.
4 If the car has travelled 110 miles, it will take ___ hours
S = D/T
S = 55 miles per hour.
D = 110 miles
T = D/S
Put the values;
T = 110/55
T = 2 hours.

Let us analyze them one by one
1. √200
we know that √100 = 10
⇒ √200 = 10√2
√2 = 1.414

The coordinates of the mid point of the given points (4,-1) and (3,-2) is found as (x,y) = (3.5, -1.5).
What exactly is the Mid - Point Theorem?The midpoint of a line segment is referred to by the midpoint theorem. It describes the coordinate points of the line segment's midpoint and can be found by averaging the coordinates of a given endpoints.It also states that a line with endpoint coordinates - [x(1), y(1)] and [x(2), y(2)] has its mid - point just at coordinate.In response to the question, we have -
A (4,-1)and B(3,-2) are our two coordinate points.
We must determine the midpoint of the this line AB.
x(m) = [x(1) + x(2)]/2
y(m) = [y(1) + y(2)]/2
A is the first coordinate point (4,-1).
Point B is the second coordinate (3,-2).
Put the given points;
x(m) = [4 + 3)]/2
x(m) = 7/2 = 3.5
Now, for y;
y(m) = [y(1) + y(2)]/2
y(m) = [-1 -2]/2
y(m) = -3/2 = -1.5

Find a vector function that represents the curve of intersection of the two surfaces. the paraboloid z = 8x 2 y 2 and the parabolic cylinder y = 3x 2 r(t) = t i j
Answers
The vector function, r(t) that represents the curve of intersection of the two surfaces, the paraboloid and the parabolic cylinder is given by < t, 3t2, 8t2 + 9t4 >. It is attained by applying the concept of vectors to the assigned problem.
What is a vector?
A vector is any quantity that contains both magnitudes as well as direction. Geometrically, one can imagine a vector as a directed line segment, whose length denotes the magnitude of the vector and the direction is shown by the arrow, which is generally taken from its tail to its head. Using an arrow with a line specifies that it is not only scalar but also has some direction.
Calculation of the vector function representing the curve of intersection of the paraboloid and parabolic cylinder
A vector function r(t) is represented as: r(t) = < x, y, z >
Given: y = 3x2 – 1
z = 8x2 + y2 – 2
Let,
x = t
Using x = t in equations 1 and 2
y = 3t2
z = 8t2 + y2
Putting the value of y in z, we get,
z = 8t2 + (3t2)2
z = 8t2 + 9t4
Substitute these values of x, y, and z in vector representation to obtain the result, i.e. < t, 3t2, 8t2 + 9t4 >
Hence, the value of vector function r(t) is: < t, 3t2, 8t2 + 9t4 >

Answers
6 half-lives are required for the concentration of reactant to decrease to 1.56% of its original value.
Using integrated rate law for first order kinetics as:
[tex][A_t]=[A_0]e^{-kt}[/tex]
Where
[tex][A_t][/tex]is the concentration at time t
[tex][A_0][/tex] is the initial concentration.
Given,
Concentration is decreased to 1.56 % which means that 0.0156 of [tex][A_0][/tex] is decomposed. So,
=> [tex]\frac{[A_t]}{[A_0]}[/tex] = 0.0156
Thus
=> 0.0156 = [tex]e^{-kt}[/tex]
When we simplify it,
Then we get,
kt = 4.1604
k = 4.1604/t
The expression for the half life is:-
Half life = 15.0 hours
[tex]t_{1/2}=\frac{ln2}{k}[/tex]
Where, k is rate constant
So,
[tex]k=\frac{ln2}{t_{1/2}}[/tex]
Apply the value of k then.
[tex]\frac{4.1604}{t}=\frac{ln2}{t_{1/2}}[/tex]
Therefore,

Answers
6(20+4) is the equivalent to 6(24) using the distributive property.
How to find an expression equivalent to 6(24) using the distributive property?The distributive Property states that it is necessary to multiply each of the two numbers by the factor before performing the addition operation when a factor is multiplied by the sum or addition of two terms. This property states that multiplying the total of two or more addends by a number will produce the same outcome as multiplying each addend by the number separately and then adding the results together.
In other words, an expression of the type
A (B + C) can be resolved as A (B + C) = AB + AC in accordance with the distributive property.
This characteristic also holds for subtraction.
A(B-C) = AB-AC
given that 6(24)
now compare the 6(24) with general form of distribution property a(b+c) = ab + ac
a = 6 and b+c = 24
Consequently, we must identify two integers the sum is 24.
These numbers 20 and 4 are suitable.
so,
6(20+4) = 6(20) + 6(4)
144 = 144
