0.18 is bigger because it is closer to 1 and 0.8 is closer to 0
Answer:
Distance, d = √((x2 - x1)² + (y2 - y1)²)
L(x1, y1) => L(-3, -1)
M(x2, y2) => M(2, 3)
Distance LM = √((2 - -3)² + (3 - -1)²)
= √((2 + 3)² + (3 + 1)²)
= √((5)² + (4)²)
= √(25 + 16)
= √ 41
= 6.4 unit
The correct answer is B)

.
The denominator of the exponent is the root we are taking. The numerator is the exponent of the radicand. This means 3 will be the denominator, since it is a cubed root, and 2 will be the numerator of m while 5 will be the numerator of n.
Answer:
68%
Step-by-step explanation:
<em><u>68-95-99.7% Rule:</u></em>
<em><u /></em>
This is the empirical rule which is used to remember the percentage of values that is within a band of the mean. We say:
- 68% of the data fall within 1 standard deviation of the mean
- 95% of the data fall within 2 standard deviation of the mean, and
- 99.7% of data falls within 3 standard deviations of the mean
Clearly, from the empirical rule, we see that about 68% of the area is between z = -1 and z = 1 (or within 1 standard deviation of the mean)
Given that the<span> iq scores for large populations are centered at 100.
To get what percent of these 78 students have scores above 100 we conduct a normal distribution probability of the data.
P(x > 100) = P(z > (100 - 100)/sd) = P(z > 0) = 1 - P(z < 0) = 1 - 0.5 = 0.5 = 50%
