A survey of 120 twelfth-graders finds that 36% were carrying more than $15 on the day of the survey. Use the margin of error to complete the following. Round to the nearest whole percent. An interval that will likely include the proportion of students in the population of twelfth-graders who carry more than $15 is ?

Answer:

A

Step-by-step explanation:

m angle b equals 59 now we have to find the arc of angle b.

so use the equation arc AC = 2(59)

arcAC = 118

360 - 118

=242

121/2

= 60.5

Answer:

B

Step-by-step explanation:

Answer:

720 pounds

Step-by-step explanation:

According to the scenario, calculation of the given data are as follows,

Number of mangoes in a barrel = 400

Each mango weight = 1.8 pounds

So, we can calculate the total weight of mangoes by using following formula,

Total weight = Number of mangoes in a barrel × Each mango weight

By putting value, we get

Total weight = 400 × 1.8 pounds

= 720 pounds

answer:

2,558

step-by-step explanation:

the formula for the volume of a cone is v=πr²h/3

with that let us 'fill in' the formula-

v=π*9.6²*26.5/3

v=2,557.51

then since you've asked us to round the answer to the nearest whole number that would be 2,558

good luck :)

side walk = incl area - excl area= 314 - 200.96 = 113.4m sq

Answer:

y = -2x - 2

Step-by-step explanation:

Given:

m = -2

Slope-intercept:

y - y1 = m(x - x1)

y + 8 = -2(x - 3)

y + 8 = -2x + 6

y = -2x - 2

Answer:

I can't see the rest of the answers, but I believe it is the first answer. Both triangles are congruent.

Answer:

To solve this problem, simply divide the total amount earned by the time in months it took to earn this total.

Therefore, divide the income of $67,452 by the 12 months it took to earn this much.

Your answer, B) $5,621.

Answer:

Step-by-step

That is the answer hope it heled you

Answer: Since this is the right triangle so

[tex]Sin B = \frac{AC}{AB} =\frac{AC}{6} \\=> AC = sin(20) * 6 = 5.478 = 5.48[/tex]

Apply Pythagorean theorem:

[tex]AC^{2} +CB^{2} =AB^{2} \\5.48^{2} +CB^{2} =6^{2}[/tex]

[tex]CB = \sqrt{6^{2} -5.48^{2} } = 2.44[/tex]

Answer: 5 quintal = 500 kilogram

Step-by-step explanation:

x = 17°

Step-by-step explanation:

total angle is 90°

so the equation is

90°=73°+ x

x = 90°-73°

x=17°

hope it helps ❤️

Answer:

First, if we have a function defined as:

[tex]G(x) = \int\limits^x_0 {f(t)} \, dt[/tex]

then:

G'(x) = f(x)

[tex]F(x) = \int\limits^x_0 {cos(t)^2} \, dt[/tex]

then:

F' = dF/dt = cos(t)^2

F'(1) = cos(1)^2 = 0.2919

If we round it up to the third digit after the decimal point we get:

F'(1) = 0.292

The correct option is the second one.

Answer:

Angles B and D

Step-by-step explanation:

Since Lines D E and Line A B are parallel hence

The angles that will represent alternate interior angles will be

Angles B and D

This is because when two parallel lines are cut  through by a transversal, the corresponding angles are congruent .

Answer:

B

Step-by-step explanation:

Answer:

zero = (-1,0)

Step-by-step explanation:

Since the slope is 3, you are going to take the given point and go back one space (behind the given point), continue to go up the lines and you should be given the point (0,-3),  then you keep this process going until you get your zero (x-axis meeting point) :)

Answer:

A, B, C, D

Step-by-step explanation:

Quadrilaterals are shapes that have a total of four sides. Rectangles, parallelograms, squares, and rhombuses all have a total of four sides. Therefore, they are quadrilaterals.

Rectangle, Parallelogram, Square and Rhombus are Quadrilaterals.

We know,

A quadrilateral is a polygon with four sides. It is a geometric shape that is characterized by having four straight sides and four vertices. The interior angles of a quadrilateral add up to 360 degrees.

As, Rectangle have four sides then it is a quadrilateral.

As, Parallelogram have four sides then it is a quadrilateral.

As, Square have four sides then it is a quadrilateral.

As, Rhombus have four sides then it is a quadrilateral.

Answer:

-1333/1000

Step-by-step explanation:

Evaluate tan(sin^-1(-4/5)).

First we need to evaluate the expression in parenthesis

sin^-1(-4/5)

= sin^-1(-0.8)

= -53.13

SUbstitute the given value into the original expression as shown;

tan(sin^-1(-4/5))

=  tan(-53.13)

= -1.333

= -1333/1000
