Hey there!

12w = 102

DIVIDE 12 to BOTH SIDES

12w/12 = 102/12

SIMPLIFY IT!

w = 102/12

w = 102 ÷ 6 / 12 ÷ 6

w = 17 / 2

w = 8 1/2

Therefore, your answer should be:

w = 17/2

Good luck on your assignment & enjoy your day!

Answer:

Population: Adults in the United States

Sample: 2276 adults in the United States

33% is a statistic.

Step-by-step explanation:

The population consists of adults in the United States because that is the wider range, and the sample is 2276 of those adults.

The value 33% is an statistic due to the definitions of both words. A statistic is defined as a fact or piece of data obtained from a study of a large quantity of numerical data. While a parameter is a numerical or other measurable factor forming one of a set that defines a system or sets the conditions of its operation.

the ratio of the number of apples to the number of oranges is 4:6. The ratio of the number of oranges to the number of pears is

Maksim231197 [3]

The answer is 64 apples, 96 oranges, and 12 pears.

Let's represent the fruit as following:
a - the number of apples,
o - the number of oranges,
p - the number of pears.

$a:o=4:6$
⇒ $\frac{a}{o}= \frac{4}{6}$
⇒ $a= \frac{4}{6}o$

$o:p=8:1$
⇒ $\frac{o}{p}= \frac{8}{1}$
⇒ $o= 8p$

Therefore:
$a= \frac{4}{6}*8p =16/3p$

Now, if $a+o+p=172$ , then:
$\frac{16}{3}p +8p+p=172$
$\frac{16}{3}p +9p172$

Since $9= \frac{9}{1} = \frac{27}{3}$ , 9p can be expressed as 27/3p:
$\frac{16}{3}p+ \frac{27}{3}p=172$
$\frac{43}{3}p =172$
⇒ $p =172* \frac{3}{43}$
⇒ p = 12
There are 12 pears.

Since o = 8p, o = 96:
o = 8 × 12 = 96
There are 96 oranges.

Since $a= \frac{16}{3}p$ , a = 64:
$a= \frac{16}{3} *12=16*4=64$
There are 64 apples.

Therefore, there are 64 apples, 96 oranges, and 12 pears.

show that the relation R in R define as R = {(a, b): a<_ b}, is reflexi when transistor but not symmetry

kati45 [8]

Answer:

R is reflexive and transitive but not symmetric.

Step-by-step explanation:

R = {(a, b); a ≤ b}

Clearly (a, a) ∈ R as a = a.

R is reflexive.

Now,

(2, 4) ∈ R (as 2 < 4)

But, (4, 2) ∉ R as 4 is greater than 2.

R is not symmetric.

Now, let (a, b), (b, c) ∈ R.

Then,

a ≤ b and b ≤ c

→ a ≤ c

→ (a, c) ∈ R

R is transitive.

Thus, R is reflexive and transitive but not symmetric.
