Step-by-step explanation:

Given:

O is the center of the Circle

Chord BC is the line segment passing from the center of circle

Chord: It is a line segment whose end points lies on the circle.

Diameter: It is defined as a line segment passing from the center of the circle whose end point lies on the circle.

Hence chord BC is a diameter of the circle as passes from the center O of the circle and its end points B,C lies on the circle.

Hence the statement is TRUE

Yes, The chord BC is a diameter of circle C.

What is Line segment?

Line segment is a part of the line which have two endpoints and bounded by two distinct end points and contain every point on the line which is between its endpoint.

The delivery truck drives at a constant speed. What is the truck's speed, in miles per hour, on the delivery route? Round the answer to the nearest whole number. Enter the answer in the box.

Answers

Answer:

Choose answer below

Step-by-step explanation:

The truck does 3 sides of the square     3 x 24 = 72

   and the truck does one entire diagonal of the square

          with side lengths 24

       diagonal = sqrt (24^2 + 24^2 ) = 33.94 miles

total miles 33.94 + 72 = 105.94 miles in 4.5 hours

    105.94 / 4.5 = 23.54 m/hr for the entire trip

The mph for the actual driving time (2.5 hours )

   105.94 / 2.5 = 42. 38 m/hr    for driving time only

Answer:

2nd option

Step-by-step explanation:

the volume (V) of the prism is calculated as

V = Ah ( A is the area of the triangular face and h is its height )

A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the height )

here b = 30, h = 8 , then

A = [tex]\frac{1}{2}[/tex] × 30 × 8 = 15 × 8 = 120 in²

with h = 15 , then

V = 120 × 15 = 1800 in³

Which statement is correct regarding the measurements of the parallelogram?

On a coordinate plane, a parallelogram has points (7, 3), (4, negative 4), (negative 5, negative 4), and (negative 2, 3).
The base is 7 and the height is 7, so the area is 7 (7) = 49 square units.
The base is 7 and the height is 3, so the area is 7 (3) = 21 square units.
The base is 9 and the height is 6, so the area is 9 (6) = 54 square units.
The base is 9 and the height is 7, so the area is 9 (7) = 63 square units

The probability of both event A and event B occurring

Answers

Answer:

A.  The probability of event B​ occurring, given that event A has occurred

Step-by-step explanation:

Conditional probability

A probability is conditional if is depends on what has already happened.

The probability that event B happens, given that event A has already happened is "B given A" or P(B | A)

Therefore, P(B | A) means "The probability of event B​ occurring, given that event A has occurred"

Additional information:

P(A | B) means "A given B", i.e. the probability of event A​ occurring, given that event B has occurred

P(A ∩ B) means the probability of event A and event B both happening.

2 is the numerator, because it is the number above the dividing line.

9 is the denominator because it is the bottom number of the dividing line.

Answers

Answer:45% ??

Step-by-step explanation: you have a higher chance of getting heads than tails


i dont really know the answer


Answer:

I believe it would be 30%

Step-by-step explanation:

If we look through the list of coin flips for each time there is a group (of 3) that has 2 tails and 1 heads, we would find that there are 10 groups.

So to solve this we can simply divide 10 (the amount of groups with 2 tails) by 30 (the total amount of groups) which gives us 33.333%. Now this isn't really an exact answer, but it is closer to 30% than it is to 35% so it would probably be safe to say that we could round down.

Explain how to use a graph of the function f(x) to
find f(3).

Answers

To find the value of f(3) we need to follow the below steps :

Step 1 : First plot the graph of f(x)

Step 2 : We need to find f(3) or the function value at x = 3 therefore, in the graph locate the point (3,0)

Step 3 : Draw a line parallel to Y-axis passing through the point (3,0) .

Step 4 : Now there exists two cases :

If the drawn line do not intersect the graph of f(x), then no value of f(3) exists for the given function of x

If the drawn line intersects the graph, then the intersection point is marked and a line parallel to x - axis is drawn passing through that marked or intersection point. And the line where it intersects the y - axis is our required value of f(3).
