Gabe went to the amusement park with $40 to spend. His ticket cost $26.50. Write and solve an inequality to show how much he mig

Goshia [24]

<h3><u>An inequality to show how much he might spend on souvenirs and snacks is:</u></h3>

$x\leq 13.5$

<h3><u>Solution:</u></h3>

Given that,

Gabe went to the amusement park with $40 to spend

His ticket cost $26.50

Therefore,

Total amount she has = $ 40

Ticket cost = $ 26.50

Let "x" be the amount he might spend on souvenirs and snacks

Therefore,

Remaining amount = 40 - 26.50

Remaining amount = 13.5

Thus she can spend less than or equal to $ 13.5 on souvenirs and snacks

Which is represented in inequality as:

$x\leq 13.5$

Thus the inequality is found

For each day that Sasha travels to work, the probability that she will experience a delay due to traffic is 0.2. Each day can be

lions [1.4K]

Answer:

0.8213

Step-by-step explanation:

-This is a binomial probability problem given by the function:

$P(X=x)={n\choose x}p^x(1-p)^{n-x}$

Given that n=21 and p=0.2, the probability that she experience a delay on at least 3 days is calculated as:

$P(X=x)={n\choose x}p^x(1-p)^{n-x}\\\\P(X\geq 3)=1-P(X$

Hence, the probability that she experience delay on at least 3 days is 0.8213

The time required for workers to produce each unit of a product decreases as the workers become more familiar with the productio

Marat540 [252]

Answer: 2.79 hours.

Step-by-step explanation:

Given that the function for the learning process is T(x) = 2 + 0.3 1 x , where T(x) is the time, in hours, required to produce the xth unit

To calculate the time for the new worker to produce 10 units, substitute 10 for x in the equation above.

T(x) = 2 + 0.31 (10)

T(x) = 2 + 3.1

T(x) = 5.1 hours

To calculate the time for the new worker to produce 19 units, substitute 19 for x in the equation above.

T(x) = 2 + 0.31(19)

T(x) = 2 + 5.89

T(x) = 7.89 hours

The time required for a new worker to produce units 10 through 19 will be

7.89 - 5.1 = 2.79 hours

The following table shows a proportional relationship between x and y.

RUDIKE [14]

Answer:

Assume x is directly proportional to y :

$y \: \alpha \: x \\ y = kx$

when y is 9, x is 2:

substitute to find value of k :

$9 = (k \times 2) \\ k = \frac{9}{2}$

Therefore, equation is:

${ \boxed{ \boxed{2y = 9 x}}}$
