Is – 7 a solution to the equation 8 {1/4x +3/4} -3 = 17

Mathematics
1 answer:
I am Lyosha [343]3 years ago
8 0

Answer:

No

Step-by-step explanation:

Start by using the distributive property to simplify 8(1/4x+3/4):

8•1/4x=2x

8•3/4=6

The equation now reads: 2x+6-3=17. Subtract 3 from six and you get 2x+3=17.

You can now proceed to answer this like any two step linear equation.

2x+3=17

-3 -3

2x=14

x=7

7 is the solution to this equation

A farmer from Whidbey Island: A man claims his whalebone can detect water. You design an experiment using a set of 4 cans, 3 emp
tatyana61 [14]

Answer:

The value is E(x) =  1.25

Step-by-step explanation:

From the question we are told that

The number of cans is n = 4

The number of can that are empty is N = 3

The number of can filled with water is k = 1

The number number of sets of cans is w = 5

Generally probability of detecting the correct can is mathematically represented as

p  =  \frac{k}{n}

=> p  =  \frac{1}{4}

=> p  = 0.25

Generally probability of not detecting the correct can is mathematically represented as

q =  1- p

q =  1- 0.25

q = 0.75

Generally the number of cans expected of the farmer to correctly identify by chance is mathematically represented as

E(x) =  w  *  p

=> E(x) =  5  * 0.75

=> E(x) =  1.25
