1. 8 cups of flour2. 26 kids/students

________________________________

1. If one batch of cookies requires two and half cups of flour. Then we'll have to multiply it into three and a half.

Solution:

2 and half cups of flour = one batch of cookies

8 cups of flour = three batches of cookies

2. If eight kids get to go to the water park for $60. Do the same as i did on the first one. Just multiply them.

$60 = eight kids

So every kids has to pay $7.5 to go to water park.

$7.5 × 8 = $60

$195 = 26 kids

$7.5 × 26 = $195

A researcher asked five of his doctor friends if they thought the new Brand X medicine that he
developed was effective. Four responded "yes." The researcher used the results to write a TV
advertisement claiming that "4 out of 5 doctors prefer Brand X medicine." Is this a valid inference?
Explain.
Use pencil and paper. Explain all of the factors that are necessary for an inference to be valid.
Is the inference valid? Explain. Choose the correct answer below.
OA. No, because the doctors asked are not a representative sample of the population of doctors.
OB. No, because 4 doctors said yes out of 9 who were asked.
OC. Yes, because 4 doctors said yes out of 5 who were asked.
OD. Yes, because the doctors asked are a representative sample of the population of doctors.

Answers

Answer:

Step-by-step explanation:

First of all, this is not math its common sense

4/5 is just an ifference. in order to prove this, the general term would be asking a factor of the doctors such as 10, and then ask.

To prove this , use algebra.

4x/5x

Shorten to 1

0.8x/1x

So you would theoretically be getting infinite amounts of doctors. but still 4/5 of them will say yes.

This is false because N0 is a cardinal number system where is omega is a ordinal.

asking five people is indefinitely not enough to determine a representatoive sample of every doctor in the world.

Find the volume of this prism.

Answers

the answer is

D.
420 cubic inches

The volume of the prism is 420 in³.

Option C is the correct answer.

We have,

From the figure,

Length = 7 in

Width = 5 in

Height = 12 in

Now,

To find the volume of the prism, we can use the formula:

Volume = Length * Width * Height

Substituting these values into the formula:

Volume = 7 * 5 * 12

Simplifying the expression:

Volume = 420 cubic inches

Thus,

The volume of the prism is 420 in³.

Triangle JKL is rotated 180 about the origin, resulting in triangle J’K’L. What are the coordinates of the vertices of J’K’L? Move the coordinates into the tae to indicate vertices of triangle J’K’L’.

HELP ME PLZ

Answers

Im so so so sorry but I don’t understand what the question is asking

The verticies of J’K’L would be, J'(-a, -b), K'(-c, -d), and L'(-e, -f).

What are transformations?

Two-dimensional figures can be transformed mathematically in order to travel about a plane or coordinate system.

Dilation: The preimage is scaled up or down to create the image.

Reflection: The picture is a preimage that has been reversed.

Rotation: Around a given point, the preimage is rotated to create the final image.

Translation: The image is translated and moved a fixed amount from the preimage.

Given, Triangle JKL is rotated 180 about the origin, resulting in triangle J’K’L.

Assuming the coordinates of J(a, b), K(c, d) and L(e, f).

We know a rotation of 180° to (x , y) ⇒ (- x, - y).

Therefore, The vertices of J’K’L would be, J'(-a, -b), K'(-c, -d), and L'(-e, -f).

Answer:

the same number as the number of sides

lines of symmetry are in a regular polygon is the same number as the number of sides.

the correct option is (D)

What is Line of symmetry?

A line of symmetry is a line that cuts a shape exactly in half. This means that if you were to fold the shape along the line, both halves would match exactly.

The number of lines of symmetry in a regular polygon is equal to the number of sides.

For example,

It has four lines of symmetry and four sides. A regular pentagon has 5 sides and 5 lines of symmetry.

Hence, lines of symmetry in a regular polygon is equal to the number of sides.
