Answer:

Step-by-step explanation:

I believe it is C. If the temperature dropped, it means it went down, so a negative option makes sense. To check, use the process of elimination.

A: The temperature dropped, not rose.

B: It only dropped 15 degrees, not 151.

D: It dropped, not rose, and only dropped 15 degrees.

Algebra KPL and LJPL are a linear pair, m_ KPL = 2x + 24, and mLJPL = 4x + 36. What are the measures of ZKPL and LJPL? (2x + 24)

denis23 [38]

Answer:

64° = ∠KPL
116° = ∠JPL

Step-by-step explanation:

The sum of the measures of a linear pair of angles is 180°.

(2x+24) +(4x+36) = 180

6x = 120 . . . . . . subtract 60, collect terms

x = 20

(2(20) +24)° = 64° = ∠KPL

(4(20) +36)° = 116° = ∠JPL

Assume that 13% of people are left-handed. If we select 10 people at random, answer the following questions:

Anastasy [175]

Answer:

0.099, 0.969,0.87,8.3.1.063

Step-by-step explanation:

Let X be the left handed people in the sample of 10 people selected.

X is binomial with n=10 and p = 0.13

a) the probability that there are exactly 3 lefties in the group

= $P(x=3) = 10C3 (0.13)^3 (0.87)^7\\= 0.09945\\=0.099$

b) the probability that there are at least 3 lefties in the group

= $P(X\geq 3) =0.9687\\=0.969$

Now Y number of right handers is binomial with n =10 and p = 0.87

c) the expected number of right-handers in the group.

$=E(Y) = np\\= 10(0.83)\\=8.3$

d) the standard deviation of the number of right-handers in the group

= $\sigma Y = \sqrt{npq} \\=1.063485\\=1.063$
