Given

$JA = 8$

$AL = 8$

$CK = 10$

Required

The perimeter of JKL

Since the mid-points of the tangents are A, B and C respectively.

$JK = JB + BK$

Where

$JB = JA = 8$

$BK = CK = 10$

So:

$JK =8+10 =18$

$JL = JA + AL$

$JL = 8+11 = 19$

$KL = CL + CK$

Where

$CL =AL = 11$

So:

$KL = 11+10 = 21$

So, the perimeter (P) is:

$P = JK+ KL +JL$

$P = 18 + 19 + 21$

$P = 58$

The federal tax code allows some items used for business purposes to be depreciated. That is, their taxable value decreases over

Phantasy [73]

Answer: T = 22,000 - 1,900n

Step-by-step explanation:

Taxable value is $22,000

The tax code allows for the depreciation of this van by $1,900 per year.

After n years therefore the total depreciation is;

= 1,900 * n

This depreciation will need to be removed from the taxable value of $22,000 to find out the taxable value left.

Formula is therefore;

T = 22,000 - 1,900n

Answer:

The probability that the maximum speed is at most 49 km/h is 0.8340.

Step-by-step explanation:

Let the random variable X be defined as the maximum speed of a moped.

The random variable X is Normally distributed with mean, μ = 46.8 km/h and standard deviation, σ = 1.75 km/h.

To compute the probability of a Normally distributed random variable we first need to convert the raw score of the random variable to a standardized or z-score.

The formula to convert X into z-score is:

$z=\frac{X-\mu}{\sigma}$

Compute the probability that the maximum speed is at most 49 km/h as follows:

Apply continuity correction:

P (X ≤ 49) = P (X < 49 - 0.50)

= P (X < 48.50)

$=P(\frac{X-\mu}{\sigma}$

*Use a z-table for the probability.

Thus, the probability that the maximum speed is at most 49 km/h is 0.8340.
