If AB is 12, what is the length of A' B'?

Answer:

300 bags of wheat

Step-by-step explanation:

We can get the answer by using algebraic expressions. If 1,200 bags means a 20% decrease in the yield from 2005, then it is 80% of the yield in 2005.

Let's solve.

Let x be the number of bags yield from 2005.

We can say: 1,200 is 80% of x

1,200 = 80% of x

1,200 = 0.80(x)

x = [tex]\frac{1,200}{0.80}[/tex]

x = 1,500

The number of bags yield from 2005 is 1,500.

Let's check.

Let x be the decrease in yield.

1,500 x 20% = x

1,500(0.20) = x

x = 300

The 20% decrease in yield is equal to 300 bags of wheat.

1,500 - 300 = 1,200 bags

The answer is correct.

Step-by-step explanation:

Conversion between Miles and Kilometer:

1 mile = 1.609km.

100 miles = 1.609km * 100 = 160.9km,

160.9km - 100km = 60.9km.

Hence the 2 places that are 100 miles apart is 60.9km further away than the places that are 100km apart.

Answer:

A)20°

Step-by-step explanation:

As we know a triangle contains 180°

So according to the question

The equation is

25°+135°+x=180°

160°+x=180°

x=180°-160°

x=20°

Answer:

<LNK = 20°

Step-by-step explanation:

[tex]angles \: of \: triangle \: add \: upto \: {180}^{0} \\ in \: that \: scalene \: triangle \\ {25}^{0} + {135}^{0} + < lnk = {180}^{0} \\ < lnk = {180}^{0} - ( {135}^{0} + {25}^{0} ) \\ < lnk = {20}^{0} [/tex]

Step-by-step explanation:

1km=1000m

so 2×101=202

then divide by 60 min

so 202÷60=3.36

Answer:

Mean = 2

Standard deviation = 1.356

Step-by-step explanation:

We are given;

Probability of taxpayers that make mistakes when filling out forms: p = 0.08

Sample size; n = 25

In binomial distribution;

Means is;

μ = np

Thus;

μ = 25 × 0.08

μ = 2

Formula for standard deviation here is;

σ = √(np(1 - p))

σ = √(25 × 0.08(1 - 0.08))

σ = 1.356

The required mean is 2 and standard deviation is 1.356 of the number of forms with mistakes she should expect to find.

Given that,

The Internal Revenue Service estimates that 8% of all taxpayers filling out forms make mistakes.

An IRS employee announces at lunch one day that she is going to check 25 randomly selected forms after lunch.

We have to determine,

The mean and standard deviation of the number of forms with mistakes she should expect to find.

According to the question,

Probability of taxpayers that make mistakes when filling out forms: p = 8%= 0.08

And sample size; n = 25

Therefore,

In binomial distribution mean is determine by the formula,

[tex]\mu = np\\\\\mu = 25 \times 0.08\\\\\mu = 2[/tex]

The mean of the number of forms with mistake she should expect to find is 2.

And, Standard deviation is determined by the formula,

[tex]\sigma = \sqrt{np(1-p)}\\\\\sigma = \sqrt{25\times 0.08 (1-0.08)}\\\\\sigma = \sqrt{2\times0.92}\\\\\sigma =\sqrt{ 1.84}\\\\\sigma = 1.356[/tex]

The standard deviation of the number of forms with mistake she should expect to find is 1.356.

Hence, The required mean is 2 and standard deviation is 1.356 of the number of forms with mistakes she should expect to find.

Step-by-step explanation:

The equation we should solve to find b is option A:sin 55°/b = sin 30°/8

What is trigonometry?

Trigonometry is a branch of mathematics that deals with the relationships between the sides and angles of triangles.

We can use the law of sines to solve for the missing side length of the triangle. The law of sines states that the ratio of the length of a side of a triangle to the sine of the angle opposite that side is constant for all sides of the triangle. In other words:

a/sin A = b/sin B = c/sin C

where a, b, and c are the side lengths of the triangle, and A, B, and C are the angles opposite those sides.

Using this formula, we can write:

b/sin B = a/sin A

Substituting the given values, we get:

b/sin 30° = 8/sin 55°

Now, we can solve for b by cross-multiplying:

b = 8(sin 30° / sin 55°)

Therefore, the equation we should solve to find b is option A:

sin 55°/b = sin 30°/8

Note that options B and C have the sine and cosine terms reversed, respectively, and option D uses the law of cosines, which is not necessary to solve this problem.
