Which angle refers to the same angle as DOF?
​

Answer:

Last option is the correct answer

[tex] y=\frac{72}{x} [/tex]

Step-by-step explanation:

When x = 36

[tex] \implies y=\frac{72}{36} = 2[/tex]

When x = 18

[tex] \implies y=\frac{72}{18} = 4[/tex]

When x = 8

[tex] \implies y=\frac{72}{8} = 9[/tex]

When x = 6

[tex] \implies y=\frac{72}{6} = 12[/tex]

Answer:

D. 20/29

Step-by-step explanation:

The sine of an angle in a right triangle is the ratio between the side opposite to the angle and the side adjacent to the angle, or [tex]sin(a) = \frac{opposite}{hypotenuse}[/tex]. The hypotenuse is the longest side of a right triangle.

In this case, the opposite side has length 20, and the hypotenuse has length 29. Therefore, the answer is

[tex]sin(a) = \frac{20}{29}[/tex].

To remember this (and the other trigonmetric ratios), you can use the acronym SOCAHTOA, where

SOH is sin(a) = opposite/hypotenuse

CAH is cos(a) = adjacent/hypotenuse

TOA is tan(a) = opposite/adjacent

Answer: 113.0cm²

Step-by-step explanation:

The surface area if a square is calculated as:

= 4πr²

where, radius = 3cm

Surface area = 4πr²

= 4 × 3.14 × 3²

= 4 × 3.14 × 9

= 113.04

= 113.0cm²

Therefore, the surface area is 113.0cm²

Step-by-step explanation:

Answer:

The 90% confidence interval for the mean difference in pulse rates for the population of study participants is between -2.9 beats per minute and 0.5 beats per minute.

Step-by-step explanation:

We have the standard deviation for the sample, which means that the t-distribution is used to solve this question.

The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So

df = 10 - 1 = 9

90% confidence interval

Now, we have to find a value of T, which is found looking at the t table, with 9 degrees of freedom(y-axis) and a confidence level of [tex]1 - \frac{1 - 0.9}{2} = 0.95[/tex]. So we have T = 1.8331

The margin of error is:

[tex]M = T\frac{s}{\sqrt{n}} = 1.8331\frac{2.97}{\sqrt{10}} = 1.7[/tex]

In which s is the standard deviation of the sample and n is the size of the sample.

The lower end of the interval is the sample mean subtracted by M. So it is -1.2 - 1.7 = -2.9 beats per minute

The upper end of the interval is the sample mean added to M. So it is -1.2 + 1.7 = 0.5 beats per minute.

The 90% confidence interval for the mean difference in pulse rates for the population of study participants is between -2.9 beats per minute and 0.5 beats per minute.

Answer:

x = 250°

Step-by-step explanation:

"Angle formed between a chord and tangent intersecting on a circle measure the half of the intercepted arc"

From the figure attached,

Angle between the chord and the tangent = 55°

Measure of intercepted arc (minor arc AB) = h°

Therefore, 55° = [tex]\frac{1}{2}(h)[/tex]

[tex]h=110^0[/tex]

And m(minor arc AB) + m(major arc AB) = 360°

h° + x° = 360°

110° + x° = 360°

x° = 360° - 110°°

x = 250°

Therefore, measure of the intercepted arc is 250°.

On solving the provide question, we can say that - the quadratic equation [tex](6a^2 + 4b)(a^2 - b)[/tex] = -4

A quadratic equation is x ax2+bx+c=0, which is a quadratic polynomial in a single variable. a 0. The Fundamental Theorem of Algebra ensures that it has at least one solution since this polynomial is of second order. Solutions may be simple or complicated. An equation that is quadratic is a quadratic equation. This indicates that it has at least one word that has to be squared. The formula "ax2 + bx + c = 0" is one of the often used solutions for quadratic equations. where are numerical coefficients or constants a, b, and c. where the variable "X" is unidentified.

slope-intercept form of an equation for the line perpendicular to y = -2x + 5 is

y = 1/2x -7

The straight line that makes 90 degrees angle with a given line is called the perpendicular to the first line. The indicator of a line perpendicular to other line is the slope that is negative reciprocal to each other.

we know the slope intercept form of an equation of line is y = mx + b

m is the slope of line and b is the y intercept.

given, equation of a line, y = -2x+5

the slope m = -2 and y intercept, b = 5

we need to write an equation in slope-intercept form that perpendicular to the above line and containing the point (8, -3)

The required line of equation will have a slope equal to the negative reciprocal of the given slope.

hence, the slope will be m = 1/2

the equation of straight line will be y = 1/2x + b

as the line passes through the points (8, -3)

so, -3 = 1/2 × 8 + b

   b = -7

y intercept of the new equation = -7

the new equation of line is y = 1/2x -7

The surface area of the prism will be equal to 366 square meters.

The space occupied by any two-dimensional figure in a plane is called the area. The area of the outer surface of any object is called the surface area.

Given that:-

The surface area of the prism will be calculated as:-

Surface area = Sum of the area of all sides

There are three rectangle faces and two triangular faces in the triangular prism.

Surface area = 3 ( area of rectangle) + 2 (area of triangle)

Suraface area= 3 ( 10 x 9 ) + 2 [( 1/2)(16 x 6)]

Surface area = 270 + 96 = 366 square meter.

Answer: D. 12,330 phones

Step-by-step explanation:

First remove the fixed cost from the operating budget so that the variable cost that can be spent on each phone is known in total:

= 951,615 - 225,378

= $726,237

With each phone costing $58.90, the total number of phones that can be produced is therefore:

= Variable budget / Variable cost per phone

= 726,237 / 58.90

= 12,330 phones
