Answer:

45.6

Step-by-step explanation:

Answer:

1.5

Step-by-step explanation:

In the given series 3 4.5 6 7.5 9 10.5

[tex]a_{1}=3[/tex]   ,    [tex]a_{2}=4.5[/tex]   ,   [tex]a_{3} =6[/tex]

As the series is arithmetic and in arithmetic series common difference is,

[tex]d=a_{2}-a_{1}[/tex]

[tex]d_{1} =4.5-3=1.5\\[/tex]

[tex]d_{2} =6-4.5=1.5[/tex]

So, common difference is 1.5

Answer:

B or 415

Step-by-step explanation:

the volume of a cone is given by the formula V = (pi × r^2 × h/3)

where,

V = volume of the cone,

r = the radius of the cone,

h = the height of the cone.

so by just plugging in the values we get the answer which is 415

if you need any further guidance make sure to ask. :)

The Volume of Cone is 414.48 cm³.

Every three-dimensional item requires some amount of space. The volume of this space is measured. Volume is defined as the space occupied by an object inside the confines of three-dimensional space. It is also known as the object's capacity.

We have,

radius = 6 cm

height = 11 cm

Now, slant height

= √r² + h²

= √11² + 6²

= √121+ 36

= √157

= 12.52 cm

Now, Volume of cone

= 1/3 πr²h

= 1/3 (3.14)(6)²(11)

= 1/3 (3.14)(36)(11)

= 414.48 cm³

15. 3

Step-by-step explanation:

Now that you already know how to find the degree of a monomial, we move to the degree of a polynomial. A polynomial is a sum of monomials. Each monomial that is part of a polynomial is called a term of the polynomial.

To find the degree of a polynomial, find the degree of each term of the polynomial. Then the highest degree of all the monomials is the degree of the polynomial.

11.

4x³y has degree 4

3x²y² has degree 4

-y³ has degree 3

The highets degree of all terms is 4, so the degree of the polynomial is 4.

12.

a has degree 1

b has degree 1

-c² has degree 2

The degree of the polynomial is 2.

13.

The degrees of the terms are, in order, 2, 2, 2.

The degree of the polynomial is 2.

14.

The degrees of the terms are, in order, 1, 2, 1.

The degree of the polynomial is 2.

15.

The degrees of the terms are, in order, 3, 2, 1.

The degree of the polynomial is 3.

Answer: (p+q)(p+3r)

Step-by-step explanation:
p²+pq+3qr+3pr

Do the grouping p²+pq+3qr+3pr=(p²+pq)+(3qr+3pr), and factor out p in the first and 3r in the second group.

p(p+q)+3r(p+q)

Factor out common term p+q by using distributive property.

(p+q)(p+3r)

Using the z-distribution, as we are working with a proportion, it is found that there is evidence that the proportion has decreased.

At the null hypothesis, it is tested if the proportion is still the same, of 27/100 = 0.27, hence:

[tex]H_0: p = 0.27[/tex]

At the alternative hypothesis, it is tested if the proportion has decreased, hence:

[tex]H_1: p < 0.27[/tex].

The test statistic is given by:

[tex]z = \frac{\overline{p} - p}{\sqrt{\frac{p(1-p)}{n}}}[/tex]

In which:

In this problem, the parameters are as follows:

[tex]n = 175, \overline{p} = \frac{30}{175} = 0.1714[/tex]

Hence, the value of the test statistic is given by:

[tex]z = \frac{\overline{p} - p}{\sqrt{\frac{p(1-p)}{n}}}[/tex]

[tex]z = \frac{0.1714 - 0.27}{\sqrt{\frac{0.27(0.73)}{175}}}[/tex]

z = -2.94.

Considering a left-tailed test, as we are testing if the propoortion is less than a value, the critical value is of [tex]z^{\ast} = -1.645[/tex].

Since the test statistic is less than the critical value for the left-tailed test, it is found that there is evidence that the proportion has decreased.

Hey there!

3(2x + 4y) - y

= 3(2x + 4y) - 1y

= 3(2x) + 3(4y) - 1y

= 6x + 12y - 1y

= 6x + 11y

LETS TEST OPTION D. FOR YOUR RESULT…

Option D.
6(x + 2y) - y

= 6(1x + 2y) - 1y

= 6(1x) + 6(2y) - 1y

= 6x + 12y - 1y

= 6x + 11y

6x + 11y = 6x + 11y which makes this statement TRUE ☑️

Therefore, your answer is:

Option D. 6(x + 2y) - y

Answer:

B. 50 feet

Step-by-step explanation:

6 times 2.5 is 15

so that means 20 also has to be multiplied by 2.5

which becomes 50

Answer: B. 50 feet

Step-by-step explanation:

      We can set up a proportion. x will be the length of the second rectangle, I will have width on the bottom (denominator) and length on the top (numerator). All units are in feet:

             [tex]\frac{20}{6} =\frac{x}{15}[/tex]

      Now we will cross multiply and solve for x:

             300 = 6x

             50 = x

             x = 50

             The length of the second triangle is B. 50 feet

Step-by-step explanation:

Number of cards in the given pile = 24

Total number of diamond cards in the pile = 8

Probability of picking up a diamond in a draw of card from the pile is given by .

There are supposed to be 300 trials.

Therefore number of times a diamond card is picked from the pile is given by 300 ×  = 100.

Out of 300 trials to pick a card, about 100 times we can expect to have picked up a diamond card from the pile.
