Answer:

5514.67 cm³

Step-by-step explanation:

The computation of the volume of the solid  figure is shown below

Given that

The total height is 20 cm

The slant height is 218 cm

radius of the base is 7 cm

the height of the hemisphere would be equivalent to the radius i.e. 7 cm

the height of the cone is

= 20 cm - 7 cm

= 13 cm

Now the volume of the cone is

= πrl

= 3.14 × 7 × 218

= 4796 cm^3

The volume of the hemisphere is

= 2 ÷3 πr^3

= 2 ÷ 3 × 3.14 × 7^3

= 718.67 cm3

Now the volume of the solid figure is

The volume of solid= volume of cone + volume of the hemisphere

= 4796 + 718.67

= 5514.67 cm³

Answer:

Ok

Step-by-step explanation:

The table completely to represent Samantha's data is

Dogs Puppies  Not Puppies Long Hair Not Long Hair

3232 1515    1717                  1111                 606

Suppose two dimensions are there, viz X and Y. Some values of X are there as X_1, X_2, ... , X_n and some values of Y are there as Y_1, Y_2, ... , Y_n

List them in title of the rows and left to the columns. There will be n \times k table of values will be formed(excluding titles and totals), such that:

Value(ith row, jth column) = Frequency for intersection of  X_i  and Y_j  (assuming X values are going in rows, and Y values are listed in columns).

Then totals for rows, columns, and whole table are written on bottom and right margin of the final table.

For n = 2, and k = 2, the table would look like:

[tex]\begin{array}{cccc}&Y_1&Y_2&\rm Total\\X_1&n(X_1 \cap Y_1)&n(X_1\cap Y_2)&n(X_1)\\X_2&n(X_2 \cap Y_1)&n(X_2 \cap Y_2)&n(X_2)\\\rm Total & n(Y_1) & n(Y_2) & S \end{array}[/tex]

where S denotes total of totals, also called total frequency.

n is showing the frequency of the bracketed quantity, and intersection sign in between is showing occurrence of both the categories together.

We are given that;

Number of dogs playing=3232

Number of puppies=1515

Now,

We can calculate the number of dogs that have long hair by using the information that there are 66 more dogs that have long hair than dogs that do not have long hair. We know that there are 1111 dogs that have long hair and 1717 dogs that are not puppies. So, the number of dogs that do not have long hair is 1717 - 66 = 1651.

We can also check that the total number of dogs is equal to the sum of the number of puppies and the number of not puppies. 1515 + 1717 = 3232.

Therefore, the table will be;

Dogs Puppies  Not Puppies Long Hair Not Long Hair

3232 1515    1717                  1111                 606

• There are 3232 dogs playing at the dog park.

• 1515 of the dogs are puppies.

• 1111 of the dogs are not puppies and have long hair.

Answer:

[tex](a)\ Total = 75[/tex]

[tex](b)\ Students = 100[/tex]

Step-by-step explanation:

Given

See attachment for complete question

Solving (a); Number of students represented.

To do this, we simply calculate the length of each bar and then sum them up.

So, we have:

[tex]Jan = 16[/tex]

[tex]Feb = 10[/tex]

[tex]Mar = 18[/tex]

[tex]Apr = 15[/tex]

[tex]May = 5[/tex]

[tex]Jun = 11[/tex]

So, the total is;

[tex]Total = Jan + Feb + Mar + Apr + May + Jun[/tex]

[tex]Total = 16 + 10 + 18 + 15 + 5 +11[/tex]

[tex]Total = 75[/tex]

Solving (b): Prediction of February students out of a total of 750.

To do this, we use:

[tex]Students = \frac{Month}{Total} * 750[/tex]

For February, we have:

[tex]Students = \frac{Feb}{Total} * 750[/tex]

[tex]Students = \frac{10}{75} * 750[/tex]

[tex]Students = \frac{10 * 750}{75}[/tex]

[tex]Students = \frac{7500}{75}[/tex]

[tex]Students = 100[/tex]

Prove that  turkey sandwiches and 9-grain wheat are  independent events

From the attachment, we have:

[tex]P(T) = 23.6\%[/tex]

[tex]P(W) = 51.7\%[/tex]

The intersection between both is:

[tex]W\ and\ T = 36[/tex]

So:

[tex]P(W\ and\ T) = \frac{36}{300}[/tex]

[tex]P(W\ and\ T) = 0.12[/tex]

[tex]P(W\ and\ T) = 12\%[/tex]

For both events to be independent, the following must be true.

[tex]P(W\ and\ T) = P(W) * P(T)[/tex]

[tex]P(W\ and\ T) = 23.6\% * 51.7\%[/tex]

[tex]P(W\ and\ T) = 12.2\%[/tex]

The calculated values of P(W and T) are estimates

[tex]12.2\% \approx 12\%[/tex]

Hence, both events are independent

Answer:

speeds of Juan and Tiauna  are 0.1984 m/s and 0.1851 m/s respectively

Step-by-step explanation:

Given:  Juan's time in the race was 5.04 seconds and Tiauna's was 5.40 seconds

Let speed of Juan and Tiana's be J m/s and T m/s respectively

In the race both Juan and Tiauna will cover equal distance. Therefore, the speed and time would have reciprocal relationship

Speed ∝ 1/Time

This means J = 1/5.04 m/s

J= 0.1984 m/

and, T = 1/5.40 m/s

T= 0.1851 m/s

Therefore, speeds of Juan and Tiauna  are 0.1984 m/s and 0.1851 m/s respectively

Answer:

a=10

Step-by-step explanation:

11a-(4a-7)=77

11a-4a+7=77

7a+7=77

7a=70

a=10

Answer:

a=10

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

11a−(4a−7)=77

11a+−1(4a−7)=77(Distribute the Negative Sign)

11a+−1(4a)+(−1)(−7)=77

11a+−4a+7=77

(11a+−4a)+(7)=77(Combine Like Terms)

7a+7=77

Step 2: Subtract 7 from both sides.

7a+7−7=77−7

7a=70

Step 3: Divide both sides by 7.

[tex]\frac{7a} {7} = \frac{70} {7}[/tex]

Thus a = 10
