Answer:

The equation of the relation ⇒ $y=\frac{6x}{z}$

y = 18

Step-by-step explanation:

∵ y ∝ x/z

∴ y = kx/z

∵ y = 18 , x = 15 and z = 5

∴ 18 = 15k/5 ⇒ 18 = 3k

∴ k = 18/3 = 6

∴ y = 6x/z

∵ x = 21 and z = 7

∴ y = (6 × 21)/7 = 18

<h3>What is Venn diagram?</h3>

A Venn diagram uses overlapping circles or other shapes to illustrate the logical relationships between two or more sets of items.

Given:

E = { 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 }

S = square numbers

E = even numbers

Suppose 56% of the registered voters in a country are Republican. If a sample of 447 voters is selected, what is the probability

o-na [289]

Answer: 0.9554

Step-by-step explanation:

Given : The proportion of the registered voters in a country are Republican = P=0.56

The number of voters = 447

The test statistic for proportion :-

$z=\dfrac{p-P}{\sqrt{\dfrac{P(1-P)}{n}}}$

For p= 0.60

$z=\dfrac{0.60-0.56}{\sqrt{\dfrac{0.56(1-0.56)}{447}}}\approx1.70$

Now, the probability that the sample proportion of Republicans will be less than 60% (by using the standard normal distribution table):-

$P(x$

Hence, the probability that the sample proportion of Republicans will be less than 60% = 0.9554

Given: K is the midpoint of JL, M is the midpoint of LN,

Novosadov [1.4K]

Answer:

Given that JK = MN, JK = KL, and LM = MN, therefore, by transitive property, we have;

KL ≅ LM

Step-by-step explanation:

The given information are;

The midpoint of the segment JL = The point K

The midpoint of the segment LN = The point M

Given that JK = MN

The two column proof is given as follows;

Statement ${}$ Reason

1) JK = KL ${}$ Definition of the midpoint of segment JL

2) LM = MN ${}$ Definition of the midpoint of a segment LN

3) JK = MN ${}$ Given

4) KL ≅ LM ${}$ Transitive property.
