Simplifying
10x + -9y = 24

Solving
10x + -9y = 24

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '9y' to each side of the equation.
10x + -9y + 9y = 24 + 9y

Combine like terms: -9y + 9y = 0
10x + 0 = 24 + 9y
10x = 24 + 9y

Divide each side by '10'.
x = 2.4 + 0.9y

Simplifying
x = 2.4 + 0.9y

In a game of poker a hand of five cards is dealt to each player from a deck of 52 cards. find the probablility of a hand contain
aalyn [17]

Answer:

0.00597

Step-by-step explanation:

Given,

Total number of cards = 52,

In which flush cards = 20,

Also, the number of spade flush cards = 5,

Since,

\text{Probability}=\frac{\text{Favourable outcomes}}{\text{Total outcomes}}

Thus, the probability of a hand containing a spade flush, if each player has 5 cards

=\frac{\text{Ways of selecting a spade flush card}}{\text{Total ways of selecting five cards}}

=\frac{^{20}C_5}{^{52}C_5}

=\frac{\frac{20!}{5!15!}}{\frac{52!}{5!47!}}

=\frac{15504}{2598960}

= 0.00597

Yasmine has 4 containers of 4 different colors of flowers to plant. She had 1/3 of each color left over when she was done planti
olga2289 [7]

Answer:

2\frac{2}{3}

Step-by-step explanation:

Given the information

  • 4 containers of 4 different colors
  • 1/3 of each color left over
  • She had planted more than 2 1/2 of the original 4 containers

=> Total color were left = 1/3 x 4 = 4/3 of the original containers

=> Total color  were planted = (1 - 1/3) x 4 = 2/3 x 4 = 8/3 of the original containers

However,  8/3 = 2\frac{2}{3}  > 2\frac{1}{2}  

So she is true, hence, the fractions to determine the total amount of containers of flowers she planted is:  2\frac{2}{3}

Hope it will find you well

In a study of pain relievers, 50 people were given product A, and all but 11 experienced relief. In the same study, 100 people w
Nataly_w [17]

Answer:

Product B performed worse in the study because 86% failed to get relief with this product, whereas only 78% failed to get relief with Product A

Step-by-step explanation:

We are given the following in the question:

Product A:

Number of people,

n_1 = 50

Number of people who received relief,

x_1 = 11

Proportion of people who received relief from product A =

p_A = \dfrac{x_1}{n_1} = \dfrac{11}{50} = 0.22 = 22\%

Proportion of people who did not received relief from product A =

1 = p_A = 1 - 0.22 = 0.78 =78\%

Product B:

Number of people,

n_2 = 100

Number of people who received relief,

x_2 = 14

Proportion of people who received relief from product B =

p_B = \dfrac{x_2}{n_2} = \dfrac{14}{100} = 0.14 =14\%

Proportion of people who did not received relief from product B =

1 = p_B = 1 - 0.14 = 0.86=86\%

Product B performed worse in the study because 86% failed to get relief with this product, whereas only 78% failed to get relief with Product A
