Answer: 90km/hour
Step-by-step explanation:
The formula for speed is given as:
= Distance / Time
where,
Distance = 120km
Time = 80 minutes = 80/60 = 1 1/3 hours
Speed = Distance / Time
= 120 / 1 1/3
= 120 / 4/3
= 120 × 3/4
= 90km/hour
The speed is 90km/hour.

If you change the sign of a point's x-coordinate, how does the location of the point change? CLEAR CHECK The point moves down and to the left. The point crosses over the x-axis. The point crosses over the y-axis. Not enough information is provided.
Answer:
The point crosses over the y-axis
Step-by-step explanation:
Given
A change in the sign of x coordinate
Required
The effect on the point location
Assume the coordinate to be (x,y).
The above point is located in the first quadrant,
When the x value changes to negative i.e. (-x,y)
The point moves from the first quadrant to the second quadrant
This implies that, the point crosses over the y-axis.
Similarly, assume the coordinate to be (-x,-y).
The above point is located in the third quadrant,
When the x value changes i.e. (x,-y)
The point moves from the first quadrant to the fourth quadrant
This implies that, the point crosses over the y-axis.

Which measure should be used to summarize the data
Answer:
Mean and Median
Step-by-step explanation:
Given the data :
285,288,289,290,299,300,308,309,312,314
To summarize the data using a measure of centre, considering that the dataset doesn't show a great deal of variation we could use either the mean or median value.
The mean, x = Σx / n
n = sample size = 10
Σx = 2994 ; n = 10
x = 2994 / 10 = 299.4
Also the median value ;
1/2 * (n + 1)th term
1/2 * (10 + 1)th term
1/2 * 11
= 5.5 th term
= (5 + 6)th / 2
= (299 + 300) / 2
= 299.5

A circle is centered on point B. Points A, C and D lie on its circumference.
If ZABC measures 46°, what does ZADC measure?
Step-by-step explanation:
given: B is the centered poin of the circle
points A,C,D lies on its circumference
measure angle ABC is 46⁰
<ADC is inscribed in the circle
<ABC is the central angle
to find: what is the measure of angle ADC?
solution:
inscribed angle therom states that an inscribe angle is half of a central angle that subtends the same arc
hence, <ADC = 1/2 × <ABC
<ADC= 1/2 × 46⁰
<ADC=1/2 ×46⁰
<ADC= 23⁰

Answer:
Quadrilateral ABCD is a rhombus, because all four sides are congruent and adjacent sides are not perpendicular .
Step-by-step explanation:
Given :
A quadrilateral with its coordinates as follows:
Where A (3, 1), B (4,4), C (7,5), D (6,2).
We will measure the length of the congruent sides by applying distance formula.
Distance formula = square root (x^2 - x^1)^2 + (y^2 - y^1)^2
So,
AB = ( insert the coordinates using the formula )
BC = ( insert the coordinates using the formula )
CD = ( insert the coordinates using the formula )
DA = ( insert the coordinates using the formula )
It all equals = squareroot 10
From the above measurement and looking into the diagram we can conclude that the Quadrilateral ABCD is a rhombus.
In rhombus the adjacent sides are not perpendicular and its diagonals are of different length.

Based on these results, estimate the probability that 3 or more kicks are made.
Answer:
You are correct that the cross section is a rectangle, because a rectangular pyramid has 4 sides connected to the top of the rectangle.
Step-by-step explanation:
We can estimate that the probability of making 3 or more kicks in a game is approximately 0.8 or 80%.
What is simulation?Simulation is the process of creating a computer model or a physical system that behaves like a real-world system or process, in order to study its behavior or performance under various conditions.
We have,
To estimate the probability that 3 or more kicks are made, we need to count the number of trials in which 3, 4, or 5 kicks were made, and divide that by the total number of trials (which is 5 in this case).
From the table,
We can see that there are three trials in which 3 kicks were made
(trials 1, 3, and 5), one trial in which 4 kicks were made (trial 4), and no trials in which all 5 kicks were made.
The total number of trials in which 3 or more kicks were made is:
= 3 + 1 + 0
= 4
To estimate the probability, we divide the number of successful trials by the total number of trials:
P(3 or more kicks made) ≈ 4/5
Therefore,
We can estimate that the probability of making 3 or more kicks in a game is approximately 0.8 or 80%.

Answer:
x = 11
Step-by-step explanation:
Assuming that segment EG is a diameter we can solve this using the straight angle theorem ( Which states that angles on a straight line add up to equal 180. Also note that central angles and there corresponding arcs are congruent. )
We are also told that CH is a bisector.
A bisector splits an angle into TWO EQUAL parts.
mDG is split into mDC and mCG
So mDC = mCG
This meaning that because mDC = 7x + -1 , mCG also equals 7x - 1
Leading to us having enough information to use the straight line theorem ( which also works with half circles and arcs. )
So 180 = 2 ( 7x - 1 ) + 2x + 6
now we solve for x
step 1 distribute the 2
2 * 7x = 14x
2 * - 1 = -2
now we have 180 = 14x - 2+ 2x + 6
step 2 combine like terms
14x + 2x = 16x
-2 + 6 = 4
now we have 180 = 16x + 4
step 3 subtract 4 from each side
4 - 4 cancels out
180 - 4 = 176
Now we have 176 = 14x
step 4 divide each side by 14
176 / 16 = 11
14x/14 = x
we're left with x = 11

Which of the following are true if event A and B are independent
Answer:
a) [tex]P(B/A) = P(B)[/tex]
Step-by-step explanation:
Step(i):-
Given that A and B are independent events
P(A∩B) =P(A) P(B)
we will use the conditional probability
[tex]P(A/B) = \frac{P(AnB)}{P(B)}[/tex]
or
[tex]P(B/A) = \frac{P(AnB)}{P(A)}[/tex]
Step(ii):-
Given that A and B are independent events
P(A∩B) =P(A) P(B)
[tex]P(B/A) = \frac{P(AnB)}{P(A)}[/tex]
[tex]P(B/A) = \frac{P(A)P(B)}{P(A)} = P(B)[/tex]

Answer:
3(4+√2)
Step-by-step explanation:
Here we need to find the perimeter of the given figure. Here the given figure is made from a triangle and a square. The side lenght of the square is 3. We need to find the hypontenuse of the triangle in order to find Perimeter .
• Using Pythagoras Theorem :-
⇒ h² = p² + b²
⇒ h² = 3² + 3²
⇒ h² = 9 + 9
⇒ h² = 18
⇒ h = √[ 9 × 2 ]
⇒ h = 3√2 .
Therefore the perimeter will be ,
⇒ P = 3√2 + 3 + 3 + 3 + 3
⇒ P = 3√2 + 12
⇒ P = 3( 4 + √2)
Hence the perimeter of the figure is 3(4+√2) .Using the line AB, name two line segments.

Answer:
4 ft = height
10 ft = base
Step-by-step explanation:
The area of a triangle is given by ...
A = 1/2bh
Filling in the given value, we get the relation ...
20 = 1/2bh
40 = bh
We know the factors of 40 are ...
40 = 1×40 = 2×20 = 4×10 = 5×8
Of the numbers that area available, only the pair 4×10 will give the desired result.
The height is 4 ft; the base is 10 ft.
