La probabilité d'un évènement A ne se réalise pas est 3/7 donc:
- P(A) = 3/7 - P(A) = 4/7
- P(A) = 4/10
- P(A) = 7/4 ​

Step-by-step explanation:

Given

Model to Actual = 5:9

5cm in Model = 9cm actual

1cm in model = (9/5)cm = 1.8cm

36cm in model = 1.8cm x 36 = 64.8cm

Answer: D $26

Step-by-step explanation:

50-(50x.3)= 35

35-6=29

29-3=26

Answer:

No, because x has multiple values for y.

Step-by-step explanation:

Any input into a function has to map into exactly one output. The input, x, has multiple values for y. Therefore, it is not a function.

Step-by-step explanation:

Answer:

1.25 or [tex]1\frac{1}{4}[/tex] pages per minute

Step-by-step explanation:

We are to determine the speed at which Sydney reads

Speed = total pages red / total minutes

50 / 40

The above fraction can be expressed its simplest form by dividing the numerator and the denominator by 10

5 / 4

the above fraction can be expressed as a mixed fraction as [tex]1\frac{1}{4}[/tex] or as a decimal as 1.25 pages per minute

Answer:

Step-by-step explanation:

Answer:

2/3

Step-by-step explanation:

Sample space for the sum of 2 spins :

Number on spinner = 2, 5, 4

____ 2 ___ 5 _____4

2___ 4 ___ 7 _____ 6

|

5___ 7 ___ 10 ____ 9

|

4___ 6 ___ 9 ____ 8

Hence,

(4, 7, 6, 7, 10, 9, 6, 9, 8)

Probability of getting a sum less than or equal to 8;

Probability = required outcome / Total possible outcomes

Required outcome =, sum ≤ 8 = 6

Total possible outcomes = 9

P(sum ≤ 8) = 6/9 = 2/3

Answer:

Sally is 23 years old.

Step-by-step explanation:

John's age is completely unknown, so it is known as x

Meanwhile, Sally's age can be represented as 3x+2

The sum of both ages is 30.

So, x+3x+2=30

Combine like terms.

4x+2=30

Subtract 2 from both sides.

4x=28

Divide both sides by 4.

x=7

John is 7 years old.

Sally's age: 3(7)+2=23

Sally is 23 years old.

Answer:

  F.  c = 0.10m + 30

Step-by-step explanation:

If you try the first value of m in each of the equations, you find all give wrong answers except the first one:

  c = 0.10m + 30

__

Here is what you get for m=5:

  F  c = 0.10(5) +30 = 30.50

  G  c = 30(5) +0.10 = 150.10

  H  c = 0.50(5) +30 = 32.50

 J   c = 30(5) +0.50 = 150.50

Answer: What number, when added to negative four is equal to negative five.

Step-by-step explanation:

Rearange the numbers to get -4+g=-5.

This eqation now reads -4 plus a number g is equal to -5, and can also be read as what number (g) added to -4 = -5.

If we were to solve for g we would get g= -1.

Answer:

the third option, "what number, when added to negative four, is equal to negative five?"

Explanation:

"what number, when added to negative four, is equal to negative five?" can be expressed as g + (- 4) = - 5, which is the same as in the equation.

i hope this helps! :D comment if you need any clarification.

Answer:

5 - 3 = 2

2x =2

x = 2x ÷ 2 = 1

Answer is 1

Answer:

5=2x-3

collect like terms

if -3 crosses the equal to sign it will change to +3

5+3=2x

8=2x

divide both sides by 2

X=4

Answer:

8 < x <22

Step-by-step explanation:

In this question we know the two sides of the triangle to be 7 and 15, let's all the other side x

One one side of the inequality we have:

7+15>x

22 > x

On the other side we have

7 + x > 15

X > 15-7

X>8

When we rearrange these inequalities above we have

8<X<22

We saw from the calculations that 8 is less than X and X is less than 22.

Step-by-step explanation:

tell Us The Base And Height Of The Triangle Briefly

I have attached the complete question with the triangle.

Answer:

x = 6

Step-by-step explanation:

From the image attached we are told to find x in the triangle.

The triangle is a right angle triangle and so we can use pythagoras theorem to find x.

x² = 6.5² - 2.5²

x² = 42.25 - 6.25

x = √36

x = 6

Step-by-step explanation:

Answer:

x = 10

TU = 24

Step-by-step explanation:

To find the value of x, we use the trapezoid mid-segment theorem

The sum of the lengths of the two parallel sides is equal to twice the length of the mid segment

Mathematically, we have this as;

2(2x+ 4) = 2x-4 + 3x + 2

4x + 8 = 5x - 2

5x -4x = 8 + 2

x = 10

TU = 2x + 4 ; = 2(10) + 4 = 20 + 4 = 24

Answer:

9x + 6

Step-by-step explanation:

5x + ( x + 6 ) + 3x

= 5x + 3x + x + 6

= 9x + 6
