Answer

Hello class!

Step-by-step explanation:

1. The mean is the average of a data set.

2. The mode is the most common number in a data set.

3. The median is the middle of the set of numbers.

Of the three, the mean is the only one that requires a formula. I like to think of it in the other dictionary sense of the word (as in, it’s mean as opposed to nice!). That’s because, compared to the other two, it’s not as easy to work with.

Answer:

n = 7

Step-by-step explanation:

sarah = m

annie = n

sarah has 21 more than annie

m = 21+n

given sarah has 28 quareters

m = 21 + n

28 = 21 + n

28 - 21 = n

7 = n

annie has 7 quarters.

Answer:

4 batches

Step-by-step explanation:

To obtain the number of batches of the recipe that can be made ;

We take the divison of the total amount of strawberry by the amount of strawberry required per batch :

Pounds of strawberry per recipe = 0.75 pound

Total pounds of strawberry = 3.15 pound

= 3.15 / 0.75

= 4.2

We round down :

4.2 batches = 4 batches of the recipe can be made

Step-by-step explanation:

The scale used by Johnny for the drawing is 1/10. This means that every 1 millimeter on the drawing represents 10 meters in reality.

To determine the scale used by Johnny for the drawing, we need to compare the measurements in the drawing to the actual measurements of the soccer field. We can set up a proportion to find the scale.

Let's denote the scale as x (the ratio of the drawing measurements to the actual measurements). According to the information provided, the width of the soccer field in the drawing is 6 millimeters, while the actual width is 60 meters.

We can put up the following proportion using the scale:

6 millimeters / x = 60 meters / 1

We can solve for x by cross-multiplying and then dividing:

6 millimeters * 1 = 60 meters * x

6 = 60x

Dividing both sides by 60:

6 / 60 = x

1 / 10 = x

Therefore, the scale used by Johnny for the drawing is 1/10. This means that every 1 millimeter on the drawing represents 10 meters in reality.

Answer:

The probability that all 3 balls are red is 18.65%, while the probability that all 3 balls are blue is 7.87%.

Step-by-step explanation:

Since a bag contains 8 red balls and 6 blue balls, and Radhika takes three balls at random from the bag, without replacement, to calculate the probability that the three balls are the same color, the following mathematical operations must be performed:

8 + 6 = 14

14 = 100

8 = X

8 x 100/14 = X

800/14 = X

57.14 = X

100 - 57.14 = 42.86

0.5714 ^ 3 = X

0.1865 = X

0.4286 ^ 3 = X

0.0787 = X

Therefore, the probability that all 3 balls are red is 18.65%, while the probability that all 3 balls are blue is 7.87%.

Answer:

V = (8 in)(5 in)(3 in) = 120 in^3

Step-by-step explanation:

The likeliest name for this shape is "rectangular prism."  Let's assume that the length, L, is 8 in; the width, W, is 5 in; and the height, H, is 3 in.

Then the volume of this rectangular prism is V = L * W * H, or

V = (8 in)(5 in)(3 in) = 120 in^3

Answer:

The volume of the triangular prism is 5676.16 cm³

Step-by-step explanation:

The area of the triangular base A = bh/2 where b = base = 28 cm and h = height = 22.4 cm.

Now, the volume of the triangular prism, V = area of triangular base, A × height of prism, h'

V = Ah' where h = height of prism = 18.1 cm

So, V = bhh'/2

Substituting the values of the variables into the equation for V, we have

V = bhh'/2

V = 28 cm × 22.4 cm × 18.1 cm/2

V = 14 cm × 22.4 cm × 18.1 cm

V = 5676.16 cm³

So, the volume of the triangular prism is 5676.16 cm³

Answer:

  ∠GDH = ∠GHD = 50°

Step-by-step explanation:

Angles FGD and EDG are alternate interior angles, so are congruent. That means angle EDG is 100°. The angle sum theorem tells us ...

  ∠EDG = ∠EDH +∠HDG

  100° = 50° +∠HDG

  50° = ∠HDG

You can find the measure of ∠DHG a couple of different ways. It is an alternate interior angle congruent to ∠EDH, so is 50°. It is one of two remote interior angles that have  a sum equal to the exterior angle FGD, so is ...

  ∠DHG = ∠FGD -∠HDG = 100° -50° = 50°

So, angles DHG and HGD both have measures of 50°. When a triangle has two angles with the same measure, it is an isosceles triangle.

Answer:

x ≈ 24.7

Step-by-step explanation:

Using the Sine rule in the triangle , that is

[tex]\frac{x}{sin71}[/tex] = [tex]\frac{15}{sin35}[/tex] ( cross- multiply )

x × sin35° = 15 × sin71° ( divide both sides by sin35° )

x = [tex]\frac{15sin71}{sin35}[/tex] ≈ 24.7 ( to the nearest tenth )
