Final answer:

The probability of drawing two chips from an urn numbered 1 through 6 such that their sum is 5 is 4/15, since there are four favourable outcomes (1,4), (2,3), (3,2), and (4,1) out of the total 15 possible combinations.

Explanation:

The question involves calculating the probability of drawing two chips from an urn, each numbered 1 through 6, such that their sum equals 5. To solve the problem, let's consider all possible combinations of two different chips that can be drawn at random:

There are 4 favourable combinations that result in a sum of 5. As each chip can be drawn only once, the total number of pairs can be given by the combination formula C(n, k) = n! / (k!(n-k)!)), where n is the total number of chips and k is the number of chips drawn. In this case, C(6, 2) = 6! / (2!4!) = 15, and so there are 15 possible pairs that can be drawn from our urn.

Therefore, the probability of getting a sum of 5 is the number of favourable outcomes divided by the total number of outcomes, which is 4 favourable combinations divided by 15 possible combinations, resulting in a probability of 4/15.

Neither statement alone is sufficient to determine the area of the trapezoid.

The area of a trapezoid can be found using the formula:

Area = (1/2) * (sum of parallel sides) * height

To find the area of the trapezoid, we need the lengths of the parallel sides and the height.

(1) The given angle does not provide information about the lengths of the sides, so it is not sufficient to find the area.

(2) The perimeter of the trapezoid does not directly give information about the lengths of the sides, so it is also not sufficient to find the area.

Therefore, neither statement alone is sufficient to determine the area of the trapezoid.

Final answer:

The finance charge for John is calculated by multiplying his unpaid balance by the periodic rate. The calculation results in a finance charge of $8.31, which is option A.

Explanation:

John's finance charge on his credit card, based on a periodic rate of 1.75% on an unpaid balance of $475, can be calculated using the formula: Finance Charge = Periodic Rate × Unpaid Balance. To find the finance charge, multiply 1.75% (or 0.0175 in decimal form) by $475. Therefore, the finance charge would be 0.0175 × $475 = $8.3125. When rounded to the nearest cent, this is $8.31, which corresponds to option A.

Answer:

The correct option is D) [tex]\frac{1}{2}[/tex]

Step-by-step explanation:

we need to find sin 30° with the reference of provided figure

Since, [tex] sin\theta=\frac{perpendicular}{hypotenuse}[/tex]    .....(1)

In fig , perpendicular is 1 and hypotenuse is

now put [tex]\theta=30\degree[/tex] in (1)

[tex] sin\theta=\frac{1}{2}[/tex]

The answer is it is compounded monthly which is 365/yr.

This is done using trial and error but I got it right at the first try.

Solution:

A = P (1+r/n) ^nt

Where:

A is the accrued amount or also known as the future value

P is the principal amount = $5,142

r is the nominal interest rate = 0.038

n is the number of compounding units = 365

t is time = 20

A = 5,142 (1 + 0.038/365) ^ 365(20)

= 5,142 (1.0001041095890410958904109589041)^7300

= 5.142 (2.13819163)

= $10994.58

To calculate the height of a tree with a 60-meter long shadow when the Sun is 30 degrees above the horizon, use the tangent trigonometric function. The tree's height is calculated to be around 34.62 meters tall.

The student is asking how to calculate the height of a tree given the length of its shadow when the Sun is 30 degrees above the horizon. This is a trigonometry problem involving a right-angled triangle, where the tree represents the opposite side, the shadow represents the adjacent side, and the angle given is the angle of elevation of the Sun. Since we have the angle and the length of the adjacent side, we can use the tangent trigonometric ratio to find the height of the tree. The tangent of an angle in a right-angled triangle is the ratio of the opposite side to the adjacent side (tangent = opposite/adjacent).

Therefore, the tree is approximately 34.62 meters tall.

When converting gram to kilogram (smaller unit to larger unit), you must divide by 10.  This means that you must move each unit to the left.  For example:

Kilo, hectogram, decagram, gram... you must move 3 steps to the left which means 5500 grams is equal to 5.5 Kilograms

Answer:

its the last graph pictured

The graph of 4x - 3y = 12 is given below.

Linear equations are equation involving one or more expressions including variables and constants and the variables are having no exponents or the exponent of the variable is 1.

Linear equations may include one or more variables.

The given linear equation is 4x - 3y = 12.

Rearranging it into slope intercept form, we get,

y = 4/3 x - 4

In order to find the points through which it passes, put some of the values of x.

When x = -3, y = -4 - 4 = -8

When x = 0, y = 0 - 4 = -4

When x = 3, y = 4 - 4 = 0

When x = 6, y = 8 - 4 = 4

...........

So the graph passes through (-3, -8), (0, -4), (3, 0) and (6, 4).

Hence the graph of the given equation is given below.
