Find the reference angle for a rotation of 347°

Answer:

length is 10 and X is 5

Step-by-step explanation:

A and D is 14 cm their opposite side is BC is 4 so AB is 10

X is 2x=10

X=10/2

X=5

Answer:

13 to 10

Step-by-step explanation:

13 boys, 10 girls

13:10

The ratio of boys to girls in the classroom is  13:10

hence option B is correct

According too the given situation

The number of boys in the classroom = 13

The number of girls in the classroom = 10

Ratio is a quantitative relationship between two numbers showing a comparable form of magnitudes of both the numbers/quantities.

Let "a" and "b" be two numbers then the Ratio of "a" and "b" is shown as formulated in equation (1)

[tex]\rm r = a:b ........(1)[/tex]

The ratio of two numbers can be found out in simplest form by dividing these two numbers such that the division results in positive natural numbers for both the quantities.

So we can conclude that   the ratio of boys to girls in the classroom are

[tex]\rm \dfrac{Boys }{Girls } =\dfrac{13}{10} \\\\Boys : Girls = 13:10 \\[/tex]

So we can conclude that the ratio of boys to girls in the classroom is  13:10

hence option B is correct

====================================================

Explanation:

The spreadsheet is shown below.

In cell B6, the formula used is the NORMINV function to get the z critical value. The name is the result of putting the words "NORM" and "INV" together, which refers to the inverse normal.

It's used to find the value of k in P(-k < Z < k) = 0.99, which in this case is roughly k = 2.576 so the z critical value is roughly z = 2.576

What you type in specifically is [tex]=\text{NORMINV}( (1-0.99)/2, 0, 1)[/tex]

The (1-0.99)/2 portion ensures that we get the alpha/2 value which in this case is 0.005

The 0,1 at the end refers to the mean and standard deviation respectively of the standard normal Z distribution.

The output of that NORMINV function is then made positive and then you'd round to 3 decimal places.

So that's how we can get excel to display z = 2.576

----------

The margin of error E formula is

E = z*sqrt(phat*(1-phat)/n)

which doesn't need an excel function to get the job done, though of course excel can handle it just fine. You'd type in the formula as shown, but be sure to reference the correct cells.

Once E is calculated, we compute the following

which are the lower (L) and upper (U) bounds of the confidence interval.

The results are L = 0.063 and U = 0.137

That confidence interval can be written in the form (0.063, 0.137) which is equivalent to saying 0.063 < p < 0.137

Step-by-step explanation:

The slope of this line is negative, and is equal to rise over run.

To find slope, count the number of spaces it has moved down or up, and then the number of spaces it has moved left or right.

The y intercept is represented by +1, and is where the line crosses the y axis.

The jar can hold a total of three tomatoes at a time.

Volume is the amount of space occupied by a three dimensional shape or object.

The tomatoes is spherical with a diameter of 6 cm (radius = 6/2 = 3cm), hence:

Volume of tomatoes = (4/3) * π * radius³ = (4/3) * π * 4³ = 268 cm³

The jar is cylinder with diameter of 8 cm (radius = 8/2 = 4) and a height of 21 cm, hence:

Volume of jar = π * radius² * height = π * 4² * 21 = 1055.6 cm³

Amount of tomatoes that can be contained in jar = 1055.6 cm³ / 268 cm³ = 3.9

The jar can hold a total of three tomatoes at a time.

Answer:

x=12

Step-by-step explanation:

Because the angles labeled 5x and 4x+12 ate opposite exterior angles, they are congruent. This means that we can set up the following equation:

5x=4x+12

Subtracting 4x from both sides, we have:

X=12

Answer:

x = 12

Step-by-step explanation:

When two parallel lines are intersected by a transversal, the alternate  exterior angles are congruent.

5x = 4x + 12

Subtract 4x from both sides,

5x - 4x = 4x - 4x + 12

x = 12

The potter probably doesn't want to apply the same glaze multiple times, in which case she has 15 choices for the first layer, 14 for the second, and 13 for the third, giving

15 * 14 * 13 = 2730

possible test vessels.

On the other hand, it's possible that the potter is fine with re-using the first glaze in the third layer. In that case, whichever glaze is used first is not counted among the options for the second layer, but it comes back for the third layer, so that there would be

15 * 14 * 14 = 2940

test vessels.

Draw a rectangle. Then draw three vertical lines inside to split the rectangle into 4 equal pieces. Shade one of the pieces to represent 1/4.

Now draw 2 horizontal lines to split that 1/4 piece into three equal smaller pieces. You should end up with a 3 by 4 grid of small squares.  There are 3*4 = 12 small squares total.
