Answer:

B.No, she did not multiply the negative integer tiles by the other negative integer tiles correctly.

Step-by-step explanation:

When multiplying these binomials, we multiply -2 by x and -2 by -3. In the diagram, we have negative x tiles, which is correct; but we have negative unit tiles. When we multiply a negative by a negative, we should get a positive result.

Here are the first five terms of an arithmetic sequence.

Assoli18 [71]

Answer:

The nth term of an AP will be 27 -7n.

Step-by-step explanation:

First five terms of the Arthemetic Sequence is given to us , which is 26 , 19 , 12 , 5

Hence here Common Difference can be found by subtracting two consecutive terms . Here which is 19 - 26 = (-7) .

Here first term is 26 .

And the nth term of an AP is given by ,

★ T_n = a + ( n - 1) d

Substituting respective values ,

⇒ T_n = a + ( n - 1 )d

⇒ T_n = 26 + (n - 1)(-7)

⇒ T_n = 26 -7n+1

⇒ T_n = 27 - 7n

<h3>Hence the nth term of an AP can be found using T_n = 27 - 7n. </h3>

Assume the random variable x is normally distributed with mean μ = 80 and standard deviation σ = 4. Find the indicated probabili

Schach [20]

Answer:

0.2278

Step-by-step explanation:

z = (x-μ)/σ,

where x is the raw score

μ is the population mean

σ is the population standard deviation

z => 72 - 80/4

= -2

Probability value from Z-Table:

P(x ≤ 72) = P(x = 72) => P(x < 72)

0.02275

Approximately =>0.2278
