The time for the teacup to last is D. m = 3.5 minutes.

<h3>What is an expression?</h3>

An expression is the statement that illustrates that the variables given. In this case, two or more components are taken into consideration to describe the scenario.

Let the number of minutes be m.

The amount of time is one minute more than twice the length of time for the teacup ride. This will be:

= (2 × m ) + 1 = 8

2m - 1 = 8

Collect like terms

2m = 8 - 1

2m = 7

Divide

m = 7/2

m = 3.5

The correct option is D.

Answer:

d) m = 3.5 minutes

Step-by-step explanation:

Now we have to,

→ find the time the teacup ride last.

Forming the equation,

→ 2m + 1 = 8

Then the value of m will be,

→ 2m + 1 = 8

→ 2m = 8 - 1

→ m = 7/2

→ [ m = 3.5 min ]

Hence, ride lasts for 3.5 min.

Solve |12x + 1| = 10<br> (9/2, 11/2)<br> (-9/2, 9/2)<br> (-112.9/2)

Reil [10]

|12x + 1| = 10

Remove the absolute value term and make two equations:

12x +1 = 10

12x +1 = -10

Now solve for both x values:

12x +1 = 10

Subtract 1 from both sides:

12x = 9

Divide both sides by 12:

x = 9/12

12x +1 = -10

Subtract 1 from both sides:

12x = -11

Divide both sides by 12:

x = -11/12

The answer would be (-11/12, 912)

Where the variance is 0.32, the mean is 0.40, and there are provided sets of probabilities, the standard deviation will be 0.566.

<h3>What is standard deviation?</h3>

The average degree of variability in your dataset is represented by the standard deviation. It reveals the average deviation of each statistic from the mean. In general, values with a high standard deviation are spread out from the mean, whereas those with a low standard deviation are grouped together close to the mean.

Here,

mean=0.4

variance=(Xn-mean)².P(x)n

=(0-0.4)²*(0.64)+(1-0.4)²*(0.32)+(2-0.4)²*0.04

variance=0.32

Standard deviation=√(variance)

=√0.32

=0.566

The standard deviation will be 0.566 where variance in 0.32 and mean is 0.40 and given sets of probability.
