Answer:
The games lost by the team is:
8 lost games.Step-by-step explanation:
First, we must know the points obtained in each case:
Won game: 3 points. Draw game: 1 point. Lost game: 0 points.If the team has 53 points, and had 11 games draws (it means 11 points), then:
Points from won and lost matches = 53 - 11 = 42How the lost games doesn't give points, the 42 points are from won games, then we calculate the won games taking into account each game gives 3 points:
Games of the remaining points = 42 / 3 = 14Taking into account the total games (33),how we know the won games (14) and the draw games (11), we can calculate the lost games:
Lost games = 33 - 11 - 14 = 8So, the number of games the team lost is 8 games.
solve the equation x^2- 10x - 3 = 0 to the nearest tenth
Answer:
x=10.29, x=-0.29
Step-by-step explanation:
Given data
x^2- 10x - 3 = 0
a=1
b=-10
c=-3
substitute into the following expression we have
x=(-b±√(b²-4ac))/(2a)
x=(-(-10)±√((-10)²-4*1*-3))/(2*1)
x=10±√100+12))/(2)
x=10±√112))/(2)
x=10±10.58/(2)
x=10+10.58/(2) , x=10-10.58/(2)
x=20.58/(2) , x=-0.58/(2)
x=20.58/2, x=-0.58/2
x=10.29, x=-0.29

The mean score of the maths test is 70 with a standard deviation if 12. Calculate the z-score of a student who got 55 marks. Interpret the result.
Answer:
Z = -1.2 ( It is below the group mean), The sudent performed less than average.
Step-by-step explanation:
From the question,
Applying
Z = (x-μ)/σ........................ Equation 1
Where Z = z-score, x = observed score or raw score, μ = mean of the score, σ = standard deviation of the score
Given: x = 55 marks, μ = 70, σ = 12
Substitute these values into equation 1
Z = (55-70)/12
Z = -15/12
Z = -1.25
Hence the z- score is negative, meaning it is below the group mean, I.e the student who get 55 marks, performed less than average

Explain how to use a number line to find the sum 7 + −2.
Step-by-step explanation:
start at 7 on the number line. move to the left (because the value is negative) 2 jumps. you will land on 5.
Answer: 5
Step-by-step explanation:
Usually you would just do 7+-2 which is also 7-2 which equals 5 but since it's a number line you do this
You would locate 7 on the number line and do the same for -2
Once done, you would take the distance 2 is from 0 and push 7 there(basically moving it to 5) and that would be how you would use a number line to find the sum of 7 + -2
Now if the 2 was positive, this would be different and you would add the distance making it 9 but since it's negative you push it towards 0 which makes it 5

Given: ∠AOB is a central angle and ∠ACB is a circumscribed angle. Prove: △ACO ≅ △BCO Circle O is shown. Line segments A O and B O are radii. Tangents C B and C B intersect at point C outside of the circle. A line is drawn to connect points C and O. We are given that angle AOB is a central angle of circle O and that angle ACB is a circumscribed angle of circle O. We see that AO ≅ BO because . We also know that AC ≅ BC since . Using the reflexive property, we see that . Therefore, we conclude that △ACO is congruent to △BCO by the .
Answer:
all radii of the same circle are congruent
tangents to a circle that intersect are congruent
side CO is congruent to side CO
SSS congruency theorem
Step-by-step explanation:
The triangle △ACO ≅ △BCO are congruent to each other by SAS postulate.
Given: ∠AOB is a central angle and ∠ACB is a circumscribed angle.
What is the triangle?A triangle is a three-sided polygon with three angles. The angles of the triangle add up to 180 degrees.
We know that the radius and the tangent are perpendicular to each other.
Then the angle ∠CAO and angle ∠CBO are of 90°.
We know that the tangent of the circle drawn from the point outside the circle will be 2, and these tangent are of equal length.
In triangle △ACO ≅ △BCO, we have
CO = CO (Common side)
∠CAO = ∠CBO = 90°
OA = OB (Radius)
Thus, the triangle △ACO ≅ △BCO are congruent to each other by SAS postulate.

He added 25 as he was trying to complete the square. He should have added (-5/2)^2 to both sides.
Rule: you take the coefficient of the middle term, divide it by 2 and square the result. You are always going to get a positive result. Add this result to both sides.

If the angles are represented in degrees, find both angles: sin(x+7)=cos(4x+8)
Answer:
[tex] m\angle 1 = 22\degree [/tex]
[tex] m\angle 2 = 68\degree [/tex]
Step-by-step explanation:
[tex] \sin(x + 7) = \cos(4x + 8) \\ \sin(x + 7) = \sin \{90 - (4x + 8) \} \\ \{ \because \cos \theta = \sin(90 \degree - \theta) \}\\ \therefore \: (x + 7) = 90 - (4x + 8) \\ x + 7 + 4x + 8 = 90 \\ 5x = 90 - 15 \\ 5x = 75 \\ x = \frac{75}{5} \\ x = 15[/tex]
(x + 7)° = (15 + 7)° = 22°
(4x + 8)° = (4*15 + 8)° = (60 + 8)° = 68°
[tex] m\angle 1 = 22\degree [/tex]
[tex] m\angle 2 = 68\degree [/tex]
