Answer choice A is correct
Class A has 26 pupils and class B has 15 pupils.
Both classes sit the same maths test.
The mean score for class A is 33.
The mean score for both classes is 39.
What is the mean score (rounded to 1 DP) in the maths test for class B?
Answer:
Concept: Real World Analysis
So we know A has an average of 33We know A+B/2= 39Hence we will solve for b [tex] \frac{33 + x}{2} = 39[/tex][tex]x = 45[/tex]Answer:
It's 49.4
Step-by-step explanation:
((26*33)+(15*x))/41＝39
((858)+(15*x))/41＝39 ‖*41
(858)+(15*x)＝1599 ‖-858

The lengths of the sides of a triangle are 3, 4, 5. Can the triangle be a right angle. Yes. No.
Answer:
Yes
Step-by-step explanation:
3 , 4 & 5 are Pythagorean Triplet numbers. When lengths of a triangle's 3 sides are Pythagorean Triplet , the triangle is a right angled triangle.
The triangle will be a right angled triangle only when the hypotenuse will have length of 5 and other 2 sides will have length of either 3 or 4.
Answer:
[tex]\boxed {\boxed {\sf Yes, \ the \ side \ lengths \ 3, \ 4, \ and \ 5\ can \ make \ a \ right \ triangle}}[/tex]
Step-by-step explanation:
If the triangle is a right triangle, then the sides will check out in the Pythagorean Theorem.
[tex]a^2+b^2=c^2[/tex]
Where a and b are the legs and c is the hypotenuse.
1. Define Sides
The legs are the 2 shorter sides and the hypotenuse is the longest.
The sides given are 3, 4 (shorter), and 5 (longest). Therefore:
[tex]a=3 \\b=4 \\c=5[/tex]
2. Check the Sides in the Theorem
Substitute the values into the theorem.
[tex](3)^2+(4)^2=(5)^2[/tex]
Solve according to PEMDAS: Parentheses, Exponents, Multiplication, Addition, and Subtraction.
Solve all of the exponents first.
(3)² = 3*3= 9 (4)²= 4*4= 16[tex]9+16=(5)^2[/tex]
(5)²= 5*5= 25[tex]9+16=25[/tex]
Add the numbers on the left side of the equation.
[tex]25=25[/tex]
This is true. 25 is equal to 25, so this triangle can be a right triangle.

The Blues Festival sold 20% of tickets at a reduced price of $30 and 30% of tickets at $40 and the rest at the door for full price of $50. With 10,000 tickets sold, how much did they earn from ticket sales in dollars?
Answer:
$430,000
Step-by-step explanation:
20% of 10,000 = 2000
therefore, 2000 x $30 = $60,000
30% of 10,000 = 3000
therefore, 3000 x $40 = $120,000
50% of 10,000 = 5000
therefore, 5000 x $50 = $250,000
add all dollar amounts together to get $430,000

A Large earthworm can travel 25 centimeter in 12 seconds. How many meters does the earthworm travels in1 minute?
We know that it can travel 25 centimetres in 12 seconds. First, we break down the minute into seconds.
60/12= 5
______________________________
Now, multiply 25 by 5.
25x5=125
__________________________________
With this knowledge, we just have to convert the centimetres, to meters.

Hello! Could you please help with these? It was due quite a long time ago. I have a D in this class and need to get my grades up.
Answer:
16. [tex]y=7x[/tex]
17. [tex]y=0.5x[/tex]
18. [tex]y=3x[/tex]
19. [tex]y=2x[/tex]
Step-by-step explanation:
Equation is [tex]y=kx[/tex] where k is a constant of proportionality.
16.
[tex]\frac{y}{x}=\frac{10.5}{1.5}=\frac{14}{2}=\frac{24.5}{3.5}=\frac{35}{5}=7[/tex]
So, equation is [tex]y=7x[/tex]
17.
[tex]\frac{y}{x}=\frac{1}{2}=\frac{2}{4}=\frac{2.5}{5}=\frac{3.5}{7}=\frac{1}{2}=0.5[/tex]
Equation is [tex]y=0.5x[/tex]
18.
[tex]\frac{y}{x}=\frac{6}{2}=\frac{9}{3}=\frac{15}{5}=\frac{18}{6}=3[/tex]
Equation is [tex]y=3x[/tex]
19.
[tex]\frac{y}{x}=\frac{4}{2}=\frac{8}{4}=\frac{14}{7}=\frac{18}{9}=2[/tex]
Equation is [tex]y=2x[/tex]
How we can differentiate between direct proportion and inverse proportion?
Answer:
Please check explanations for answer
Step-by-step explanation:
Here, we want to differentiate between inverse and direct proportion
Let x and y be two quantities
If they are directly proportional;
x/y = k
x = ky
where k is proportionality constant
If inversely;
xy = k
In verbal terms;
For direct proportionality, when one value increase, the other too does so and vice versa
For inverse, when one value inverse, the other decrease

in the following figures find the value of angle COD if angle abc is equal to 75 degree and a b is equal to CD
Angle AOB is given as 75 degrees.
O is the center of the circle so AO and CO are the same length. AB and CD are the same length, so angle COD would be the same as AOB
COD = 75 degrees.
Answer:
75°
Step-by-step explanation:
It is given that:
AB and CD are chords of the circle which are equal. Equal chords subtends equal angles at the center of the circle. [tex] \because m\angle AOB = 75\degree [/tex] [tex] \therefore m\angle COD = 75\degree [/tex]Jaysen helps his mom in gardening. The produce is sold in the market for $ 17 a bag .

f (x) = 2x² - 10x + 13
Find f (-4)
Answer:
85
Step-by-step explanation:
In this question, you would solve by plugging in -4 to x.
Solve:
f(-4) = 2(-4)² - 10(-4) + 13
= 2(16) + 40 + 13
= 32 + 40 + 13
= 72 + 13
= 85
f(-4) = 85
