NEED HELP it’s a test please some one

Mathematics
1 answer:
Bezzdna [24]3 years ago
8 0

Answer:

1.  The correct answer is B. <em>N</em>

3.  The answer is C.) Associative Property of Addition

Step-by-step explanation:

1.  Since - \frac{\sqrt{64} }{2}  = -4 , then it means that -4 cannot be a natural number (<em>N</em>). By definition, natural numbers ( <em>N </em>) are counting numbers that are positive integers.

3. According to the Associative Property of Addition:

   (<em>a</em> + <em>b</em> ) + <em>c</em> =  <em>a </em>+ (<em>b </em>+ <em>c </em>)

  This definition matches your test question, "(7<em>a</em> * 2b) + 3c = 3c + (7<em>a</em> * 2b)"

Hope this explanation helps :)

Insect Weights Consider a dataset giving the adult weight of species of insects. Most species of insects weigh less than 5 grams
Ann [662]

Answer:

Step-by-step explanation:

71 grams would definitely be an outlier on the high side, whereas "most" species would weigh much less.  Thus, the graph of this distribution of weights would be skewed towards the lower side, that is, to the left.

Simplify the expression. (3x/y)^-3
AysviL [449]

Answer:

y^3/(27 x^3)

Step-by-step explanation:

Simplify the following:

((3 x)/y)^(-3)

((3 x)/y)^(-3) = (y/(3 x))^3:

(y/(3 x))^3

Multiply each exponent in y/(3 x) by 3:

(y^3)/((3 x)^3)

Multiply each exponent in 3 x by 3:

y^3/(3^3 x^3)

3^3 = 3×3^2:

y^3/(3×3^2 x^3)

3^2 = 9:

y^3/(3×9 x^3)

3×9 = 27:

Answer:  y^3/(27 x^3)

HELP ME PLEASE WILL MARK BRAINLIEST
Natali [406]

Answer:

y = 7, x = 7

Step-by-step explanation:

11y + 13 = 90

11y = (90 - 13)

11y = 77

y = 7

2x + 6 = 20 (because 20 is half of 40)

2x = (20 - 6)

2x = 14

x=7
