Using the law of sines, supposing C = 30º, the angle of each observer with the sailboat is:

Suppose we have a triangle in which:

The lengths and the sine of the angles are related according to the following rule:

[tex]\frac{\sin{A}}{a} = \frac{\sin{B}}{b} = \frac{\sin{C}}{c}[/tex]

The measure of angle B is found as follows:

sin(B)/10 = sin(C)/20

sin(B)/10 = 0.5/20 (sin(C) = 0.5)

sin(B) = 5/20

sin(B) = 0.25

B = arcsin(0.25)

B = 14º.

The measure of angle A is found as follows:

sin(A)/25 = sin(C)/20

sin(A)/25 = 0.5/20 (sin(C) = 0.5)

sin(A) = 12.5/20

sin(A) = 0.625

A = arcsin(0.625)

A = 136º.

The problem is incomplete, hence we suppose that the angle C is of 30º and problem asks for the angle measure of each angle.

In a bar graph the length of the bar need not be in proportion to the information being False.

Bar graph. A bar chart is frequently used to compare values of different things at a specific time. It presents information visually using rectangles (bars). It generally serves as a visual aid for proportions, patterns, comparisons, and contrasts.

To represent value, it makes use of bars that stretch to various heights. Vertical bars, horizontal bars, grouped bars (several bars that compare values in a category), and stacked bars can all be used to construct bar graphs (bars containing multiple types of information).

A relationship is proportionate if its graph is a line or ray that passes through the origin. It is not proportionate if the line or ray does not go through the origin. Additionally, something is not proportionate if it is not linear.

It is to be noted that, given the dilation factor stated above, the coordinates of S' is (4, 3).

The mathematical Definition of Dilation is given as a transformation that allows you to resize an object. Dilation is a technique for making items bigger or smaller. This transformation yields a picture that is identical to the original shape. However, there is a size discrepancy in the form.

The computation for the above result is given as follows:

Given that RST has vertices R(0,0), S(6, 3), and T(3, -3); and

The image R'S'T' is the image of RST after a dilation with center (0,0) with scale factor 2/3,

We must determine the coordinates of point S'.

The coordinates of S' can be determined by multiplying both the x and y - coordinates of the point S with the scale factor 2/3.

Let us look at x- coordinate with point S and multiply it with the scale factor of 2/3.

we have: 6 x 2/3 = 4

Hence, x- coordinate for S' = 4

Redo for Y

3 x 2/3 = 3

Hence, y- coordinate for S' = 3

Hence the coordinates of S' is (4, 3).

Hence having applied the principle of dilation, the coordinates of S' are (4,3)

A confidence interval exists "a range of values that's likely to contain a population value with a certain degree of confidence. It exists often denoted a % whereby a population means lies between an upper and lower interval".

The margin of error exists the range of values below and above the sample statistic in a confidence interval.

The confidence interval for the difference of means exists given by the following formula:

The point of estimate for [tex]$\mu_1-\mu_2$[/tex] exists just given by:

[tex]$\bar{X}_1-\bar{X}_2=5.84-3.96=1.88$$[/tex]

In order to estimate the critical value [tex]$t_{\alpha / 2}$[/tex] we require to estimate first the degrees of freedom, given by:

[tex]$d f=n_1+n_2-1=25+25-2=48$$[/tex]

Since the Confidence is 0.95 or 95 %, the value of [tex]$\alpha=0.05$[/tex]and α 2 = 0.025, and we can utilize excel, a calculator or a table to estimate the critical value. The excel command would be: " = -T.INV (0.025, 48) ". And we see that [tex]$t_{\alpha / 2}=2.01$[/tex]

In order to replace into formula (1), we get

[tex]$1.88-2.01 \sqrt{\frac{2.211334^2}{25}+\frac{2.35372^2}{25}}=0.582$[/tex]

In case the 95 % confidence interval would be given by

[tex]$0.582 \leq \mu_1-\mu_2 \leq 3.178$[/tex]

Because all the values for the confidence interval are higher than 0, we may infer that there are significant differences between the means of the two groups in this case, with the mean for group 1 (Medicine) being considerably higher than the mean for group 2 (Placebo) at 5% of significance.

(x^2 - 7) ( x^2 +2) =0

Using the zero product property

x^2 -7 =0     x^2 + 2 =0

x^2 =7            x^2 = -2

Taking the square root of each side

Fabric bought by Paul and Rita to make a shirt was 1 7/8 m and 1 3/4 m respectively , Paul bought 1/8 m more than Rita.

As given in the question,

Length of fabric bought by Paul to make his shirt = 1 7/8 m

Length of fabric bought by Rita to make his shirt = 1 3/4 m

Convert length of fabric into proper fraction

Paul fabric = 1 7/8 m

                 = 15 /8 m

Rita fabric = 1 3/4 m

                = 7 /4 m

Length of Paul fabric more than Rita

Length of more fabric bought by Paul than Rita = (15 /8) - ( 7/4)

                                                                          = (15/8) - (14/8)

                                                                          = 1/8 m

Therefore, fabric bought by Paul and Rita to make a shirt was 1 7/8 m and 1 3/4 m respectively , Paul bought 1/8 m more than Rita.

[tex]y=-\dfrac{2}{3}x+490[/tex]

Step-by-step explanation:

[tex]\boxed{\begin{minipage}{6.3 cm}\underline{Slope-intercept form of a linear equation}\\\\$y=mx+b$\\\\where:\\ \phantom{ww}$\bullet$ $m$ is the slope. \\ \phantom{ww}$\bullet$ $b$ is the $y$-intercept.\\\end{minipage}}[/tex]

Given equation:

[tex]2x + 3y = 1470[/tex]

To change the equation to slope-intercept form, isolate y:

[tex]\implies 2x + 3y -2x=1470 -2x[/tex]

[tex]\implies 3y=-2x+1470[/tex]

[tex]\implies \dfrac{3y}{3}=\dfrac{-2x+1470}{3}[/tex]

[tex]\implies y=-\dfrac{2}{3}x+\dfrac{1470}{3}[/tex]

[tex]\implies y=-\dfrac{2}{3}x+490[/tex]

Therefore:

To graph this line with the slope-intercept method:

To write the equation in function notation, replace the y-variable for f(x).

[tex]\implies f(x)=-\dfrac{2}{3}x+490[/tex]

The graph of the function represents:

The y-intercept of the graph is (0, 490).

To find the x-intercept, set the function to zero and solve for x:

[tex]\implies -\dfrac{2}{3}x+490=0[/tex]

[tex]\implies -\dfrac{2}{3}x=-490[/tex]

[tex]\implies -2x=-1470[/tex]

[tex]\implies x=735[/tex]

Therefore, the x-intercept is (735, 0).

The graph of the function is attached.

If Sal's total profit on lunch specials for the next month is $1,593 (where the profit amounts are the same) the equation would be 2x + 3y = 1593 and the function would be:

[tex]g(x)= -\dfrac{2}{3}x+531[/tex]

As the coefficient of the x-variable has not changed, the slopes of the two functions are the same.

As the total profit has changed, the intercepts are different.

The y-intercept of the first function is (0, 490) and its x-intercept is (735, 0).  Whereas the y-intercept of the second function is (0, 531) and its x-intercept is (796.5, 0).
