Does x=5 satisfy the equation 3x + 2 +5x= 95 explain

Answers

Answer:

No

Step-by-step explanation:

3x + 2 +5x

if x=5

3(5)+2+5(5)

=15+2+25

=42 which is not equal to 95

No, it doesn't satisfy the equation

Step-by-step explanation:

3x + 2 +5x = 95

Now putting the value of x

3×5 + 2 + 5×5 = 95

15 + 2 + 25 = 95

42 ≠ 95

Hence, x = 5 doesn't satisfy the equation 3x + 2 +5x= 95

Becky has 30 T-shirts in a drawer: 12 concert shirts, 8 team shirts, and 10 plain shirts. Of
the 10 shirts she randomly selects to give to charity, 3 are concert shirts. How does this
frequency compare to the expected frequency based on the probability of randomly
selecting a concert T-shirt?

Answers

Answer:

The chance of her selecting a Cocert shirt are 12/30 which means therw is more probability she would choose at least one and the least probability to choose a Team sirt since the odds are 8/30 so it is expected she would select 4 concert shirts not 3, at lest for me.

The admission fee at an amusement park is $15.50 for children and $20.00 for adults. One day 217 people entered the park and the total admissions fees collected was $3.782
Define your variables as
"C" = # of children
"a" = # of adults
Write a system of equations to represent this information solve the system to find out how many children and how many adults came to the amusement park that day.

Answers

Answer:

Children = 124

Adults = 93

Step-by-step explanation:

x = children

y = adults

x + y = 217

x = 217 - y

15.50x + 20y = 3782

15.50 (217-y) + 20y = 3782

3363.50 - 15.50y + 20y = 3782

4.5y = 3782 - 3363:50

y = 418.50/4.5

y = 93

x + 93 = 217

x = 217 - 93

x = 124

A biologist is developing two new strains of bacteria. Each sample of Type 1 bacteria produces four new viable bacteria, and each sample of Type II bacteria produces three new viable bacteria. Altogether, at least 240 new viable bacteria must be produced. At least 20, but not more than 60, of the original samples must by Type I. Not more than 70 of the original samples can be Type II. A sample of Type I costs $5 and a sample of Type II costs $7. How many samples of each bacteria should the biologist use to minimize the cost? What is the minimum cost?

Answers

The cost can be optimized by using a Linear Programming given the  linear constraint system

To minimize the cost, the biologist should use 60 samples of Type I bacteria and 0 samples of Type II bacteria

Reason:

Let X represent Type 1 bacteria, and let Y, represent Type II bacteria, we have;

The constraints are;

4·X + 3·Y ≥ 240

20 ≤ X ≤ 60

Y ≤ 70

P = 5·X + 7·Y

Solving the inequality gives;

4·X + 3·Y ≥ 240

[tex]Y \geq 80 - \dfrac{4}{3} \cdot X[/tex] (Equation for the inequality graphs)

The boundary of the feasible region are;

(20, 70)

(20, 53.[tex]\overline 3[/tex])

(60, 0)

(60, 70)

The cost are ;

[tex]\begin{array}{|c|c|c|}X&Y&P= 5\times X + 7 \times Y\\20&70&590\\20&53.\overline 3&473.\overline 3\\60&0&300\\60&70&790\end{array}\right][/tex]

Therefore, the minimum cost of $300 is obtained by using 60 samples of Type I and 0 samples of Type II
