Sample space for the sum of 2 spins :

Number on spinner = 2, 5, 4

____ 2 ___ 5 _____4

2___ 4 ___ 7 _____ 6

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:

  16

Step-by-step explanation:

There are several ways to go at this. Perhaps the simplest is to put the expression into your calculator.

__

Using the rules of exponents, you recognize ...

  a^-b = 1/a^b

  (a^b)^c = a^(bc)

  (a^b)(a^c) = a^(b+c)

__

So, we can rewrite the expression to be ...

  [tex]\displaystyle\frac{1}{2}\cdot\left(\frac{1}{2}\right)^{-5}=2^{-1}\cdot(2^{-1})^-5\\\\=2^{-1}\cdot2^{(-1)(-5)}=2^{-1}\cdot2^5\\\\=2^{-1+5}=2^4=\boxed{16}[/tex]

Two sides of a triangle have lengths 7 and 15. Which inequality represents the possible lengths for the third side , x?

Answers

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.

The electric current is I, is amperes, in a circuit varies directly as the voltage V. When 12 volts are applied the current is 4 amperes. What is the current when 18 volts are applied

Answers

Answer: 6 A

Step-by-step explanation:

Given

Current varies directly with Voltage

i.e.

when V=12 V, I=4 A i.e.

[tex]\Rightarrow 12=4R\\\Rightarrow R=3\ \Omega[/tex]

Sally's age is 2 plus 3 times John's age. Together, Sally and John's age equals 30. How old is Sally?

Answers

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.

Find the value of in the triangle shown below.

Answers

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
