Answer:

opinion

Step-by-step explanation:

2 different sets of data can have the same mean:

for example

4, 5, 6 ---> has a mean of 5

2,6,7 ---> also has a mean of 5

hence it is NOT a fact that if the means are the same, that it must be the same data set

Answer:

59.5cm^2

Step-by-step explanation:

Area of a trapezoid is calculated by dividing the sum of parallel sides and that's multiplied by height

(12.5 + 4.5) ÷ 2 × 7 = 59.5cm^2

Answer:

y + 2 = -2(x - 3)^2

Step-by-step explanation:

We can see immediately that the vertex is at (3, -2).  

The vertex form of the equation of a parabola is

y - k = a(x - h)^2.

If the parabola opened upward, the equation would be y + 2 = 2(x - 3)^2.  But seeing that this particular parabola opens downward, the equation is

y + 2 = -2(x - 3)^2.

Check:  Does the point (2, -4) satisfy this equation?

-4 + 2 = -2(2 - 3)^2 becomes -2 = -2(-1)^2, which is true.

Answer:

1. 3(2)+(4)-(4)=6

2. 2(8)-3(8)+4= -4

3. 4-16-16= -28

Step-by-step explanation:

Answer:

If you have this as an answer, 27

(The question is "what number is not part of the solution set to the inequality below?)

Step-by-step explanation:

w - 10 ≤ 16

w - 10 + 10 ≤ 16 + 10

w ≤ 26

11, 15, and 26 are all either less than, or equal to 26. Only 27 is not.

Answer:

D

Step-by-step explanation:

Using the changing base formula, log base 2 raised to 7 can be written as log7/log2

The correct answer is D. log(7) / log(2).

To find the equivalent of log2(7), you can use the change of base formula for logarithms.

The change of base formula states that log base a of b is equal to log base c of b divided by log base c of a.

In this case, we want to find the equivalent of log2(7), so we can use the change of base formula with base 10 as follows:

log2(7) = log(7) / log(2)

Therefore, the correct answer is D. log(7) / log(2).

Step-by-step explanation:

Dividing a whole cantaloupe into eighths will give you 8/8 or 1. When it is cut in half then divided there is one half of 8/8 or there are 4/8 in one half. This is true because 1/2 and 4/8 are equal terms.

Answer:

Total paper required = 165 cm²

Step-by-step explanation:

Paper required to cover the entire block = (Surface area of the prism at the base - area of the top of the prism) + Lateral surface area of the pyramid

Surface area of the rectangular prism = 2(lb + bh + hl)

(here l, b, h are the length, width and height respectively)

                                                               = 2(5×5 + 5×4 + 4×5)

                                                               = 2(25 + 20 + 20)

                                                               = 2×65

                                                               = 130 cm²

Area of the top of the prism = (side)²

                                              = 5²

                                              = 25 cm²

Lateral area of the square pyramid = 4 × Area of one lateral side

                                                          = 4 × [tex][\frac{1}{2}(\text{Base})(\text{Height})][/tex]

                                                          = 4 × [tex][\frac{1}{2}(5)(6)][/tex]

                                                          = 60 cm²

Total paper required = (130 - 25) + 60

                                   = 105 + 60

                                   = 165 cm²

[tex]\boxed{\sf \ 48 \ }[/tex]

Step-by-step explanation:

Hello,

the sum of all angles of the triangle at the left must be 180

so the last one is 180 - 80 - 60 = 40

and then the angle at the bottom left of the second triangle is 180 - 40 -72 = 180 - 112 = 68

and then the angle that we have to find is 180 - 64 - 68 = 48

V = 729 cm³

Step-by-step explanation:

side length a = 9 cm

face diagonal f = 12.727922061358 cm

solid diagonal d = 15.58845726812 cm

surface area S = 486 cm²

volume V = 729 cm³

Formula: V=a³

Answer:

Answer is A

Step-by-step explanation:

(14x^4y^6)/(7x^8y^2)

because everything is one term, you can split into three terms

14/7, x^4 / x^8 , and y^6/y^2

multiplying these three terms will get us the starting term

14/7 = 2

x^4 / x^8

with division of exponents, you subtract the smaller exponent (4), from the big exponent (8), and leave it on the same side (bottom) as the big exponent

1/x^4

same thing with our y's

y^6/y^2

this time, the term stays on the top

y^4

take the simplified terms and multiply them together

(2) * (1/x^4) * (y^4) =

A: (2y^4) / (x^4)
