The nutrition committee at a middle school has decided to find out which vegetables are most popular among the 500 students at the school. Which sampling method is the BEST choice to use?

Ask all the students from a randomly chosen class of 25 students to choose their favorite vegetables.

Ask 100 randomly chosen students from the student population to choose their favorite vegetables.

Ask the parents of 100 randomly chosen students to choose their favorite vegetables.

Ask 25 students who have purchased vegetables during lunch to choose their favorite vegetables.

Answers

Answer 1
the answer is b.

a is biased because it is only one class answering.

c is wrong because the school is supposed to survey children.

d is biased because children who normally purchase vegetables are more likely to like ones that other students don’t like.

Give your answer correct to three decimal places.

Answers

[tex] \huge \green{\underbrace{ \red{\rm \: Answer}}}[/tex]

To find the area of this square, we have to figure out what to do with given radius

r=16r=16 mm.

Radius makes half of the square's diagonal, therefore: d=2r=32d=2r=32 mm. Now we have to find the side aa to find the area.

To find aa, use the Pythagorean Theorem.

[tex] d^{2}&=a^{2}+a^{2} \\ 32^{2}&=2a^{2}\\ 1024&=2a^{2}\\ 512\text{ mm}^{2}&=a^{2}a^{2}[/tex]

Set the equation accordingly.

Substitute for d.

You can keep a2 as we will use it in the area.

Answers

Answer:

Step-by-step explanation:

angle 2 is 43 degree because angle 2 and 43 are vertically opposite angle and vertically opposite angles are always equal.

angle 1 is 137 degree because the sum of two angles in a straight line is always 180 degree.so

43+angle 1=180 degree

angle 1=180-43 degree

angle 3 is 137 degree because the relation between between angle 3 and 137 degree is vertically opposite angles and vertically opposite angles are always equal.

vertically opposite angles=e and c

complementary angle=b and c

supplementary angle=e and d

10: angle 2 is 43 because it is vertical to angle 43. Angle 1 is 137 (180-43) and angle 3 is also 137 because 1 and 3 are vertical angles.

11: a) e and c
B) c and b
C) c and d
D) c and b, c and d, d and e, e and a, a and b
E) c is 30, b is 60, a is 90, e is 30, d is 150

The diameter of a professional baseball mound is 18 feet. The radius of a little league baseball mound is 5 feet. What is the difference in the areas?

Answers

Answer:

175.93 feet

Step-by-step explanation:

First, you divide 18 by 2 to get the radius which is 9. Then you do nine squared. Lastly, you do 64 times 3.14 to get 254.47 (rounded)

Now, you do 5 squared which is 25. Then you multiply 25 by 3.14 to get 78.54 (rounded).

Now you subtract

254.47 - 78.54 = 175.93

Note: I rounded these in the example, the decimal places still go on so the rounded answers may not subtract to the correct answers because all the decimal points weren't shown, but the answer is correct.

you subtract 18 feet from 5 feet and get 13 feet

Answer:

Perimeter = 33.4248cm

Area = 29.42478cm²

Step-by-step explanation:

Perimeter = half circle + rectangle length + radius + 90degree section + rectangle length + radius

radius of the circles = (14 - 10)/2 = 2

Perimeter = 2π + 10 + 2 + π + 10 + 2

Perimeter = 3π + 24 = 33.4248cm

Area = half circle + rectangle + quarter circle

Area of Base B =45×25 = 1125 cm²

perimeter of base P = 2(45+25) = 140 cm

Surface area = 2B + Ph

A = 2×1125 + 140×15= 4350 cm²

Voume = Bh = 1125×15= 16875 cm³

For question 2,

The rectangle is being reduced by a scale factor of 3/4. What is the area of the new image?

F. 180 cm²
G. 90 cm²
H. 160 cm²
J. 75 cm²

Answers

Answer:

The rectangle is being reduced by a scale factor of 3/4, which means each side is reduced by the scale factor of 3/4. Therefore, we have 8* (3/4) = 6, and 20* (3/4) = 15. So, the new side lengths are 6 and 15, and so the area is 90 (6x15).

Answer:

90 cm^2

Step-by-step explanation:

The side lengths are reduced by 3/4

8 * 3/4 = 6

20 * 3/4 = 15

The new side lengths are 6 cm by 15 cm

The area is

A = l * w

A = 6*15 = 90 cm^2

Find the missing sides from the right-angled triangled given below

Answers

Answer:

8 cm

Step-by-step explanation:

[tex] \large{ \tt{❃ \: STEP - BY - STEP \: EXPLANATION}} : [/tex]

We're provided : In right angled triangle PQR , The length of of PR & length of PQ are 10 cm & 6 cm respectively & we're asked to find out the length of OR.

You need to know : The longest side, which is the opposite side of right angle is the hypotenuse ( h ) . When the reference angle is not given , You can assume the remaining sides either perpendicular ( p ) or base ( b ) .

Here , Hypotenuse ( h ) = 10 cm , Base ( b ) = ? & Perpendicular ( P ) = 6 cm

Before solving, You will have to know : The square of the hypotenuse of a right - angled triangle is equal to the sum of square of the remaining two sides.

[tex] \large{ \tt{❁ \: LET'S\: START}} : [/tex]

[tex] \boxed {\large{ \bf {\: ♕ \: {h}^{2} = {p}^{2} + {b}^{2} }}}[/tex]

- Plug the known values and then simplify !

[tex] \large{ \tt{ ↦ \: {10}^{2} = {6}^{2} + {b}^{2} }}[/tex]

[tex] \large{ \tt{↦100 = 36 + {b}^{2} }}[/tex]

[tex] \large{ \tt{↦36 + {b}^{2} = 100 }}[/tex]

[tex] \large{ \tt{ ↦{b}^{2} = 100 - 36}}[/tex]

[tex] \large{ \tt{↦ {b}^{2} = 64}}[/tex]

[tex] \large{ \tt{↦b = \sqrt{64}}} [/tex]

[tex] \boxed{ \large{ \tt{↦ \: b = 8 \: cm}}}[/tex]

Hence , The length of QR is 8 cm .

Answers

Answer:

x = 37

Step-by-step explanation:

The angle with a measure of 74 degrees and the angle labeled "2x" are vertical angles

Vertical angles are congruent ( equal to each other )

Hence, 74 = 2x

             ^(note that we just created an equation that we can use to solve for x)

Now we solve for x

74 = 2x

step 1 divide each side by 2

74 / 2= 37

2x / 2 = x

we're left with x = 37
