Answer:
the probability that a randomly chosen test-taker will score 142 or lower = 0.8643
Step-by-step explanation:
We are given;
Data point; x = 142
Mean; μ = 153
Standard deviation; σ = 10
So,let's find the z-score using;
z = (x - μ)/σ
z = (142 - 153)/10
z = -1.1
From the z-distribution table attached, the probability is;
P(z < -1.1) = 1 - 0.13567 ≈ 0.8643
<h2><u>Answer</u>:-</h2>
1) -11 + <u>2</u><u>6</u> = 15
2) <u>2</u> - (-3) = 5
3) <u>1</u><u>1</u> + (-4) = 7
4) <u>5</u> + -8 = -3
5) -2 + <u>3</u> = 1
6) <u>8</u> - 12 = -4
Answer:
3n^2(n^2+7n+9)
Step-by-step explanation:
Find the common factor. In this case, it is 3n^2. Take out the common factor of the integers.
So, therefore it is
3n^2(n^2+7n+9)
