Answer:

Option A is correct

$0.30 per lb per year

Step-by-step explanation:

As per the statement:

The price of apples went from $1.99 per lb to $3.19 per lb in four years.

rate of change in the price of apples in 4 years = $3.19-$1.99 = $1.2 per Ib

We have to find the rate of change of the price of apples per year.

In 4 years, rate of change in price = $1.2 per Ib

then;

In 1 year, rate of change in price = $0.3 per Ib

Therefore, $0.30 per lb per year is the rate of change of the price of apples.

Solve the equation using the distributive property and properties of equality. 2 (x minus 8) = 68 What is the value of x?

SVEN [57.7K]

Answer:

x=42

Step-by-step explanation:

2(x-8)=68

Distribute the 2

2x-16=68

Use the addition property of equality (add 16 to both sides)

2x=68+16

2x=84

Use the division property of equality (divide both sides by 2)

x=84/2

x=42

LUCKY_DIMON [66]

Which statement is true?

The probability that a randomly selected silver medal was awarded to Great Britain is StartFraction 17 Over 99 EndFraction.
The probability that a randomly selected medal won by Russia was a bronze medal is StartFraction 32 Over 103 EndFraction.
The probability that a randomly selected gold medal was awarded to China is StartFraction 88 Over 137 EndFraction.
The probability that a randomly selected medal won by the United States was a silver medal is StartFraction 104 Over 339 EndFraction.

Answer:

(A)The probability that a randomly selected silver medal was awarded to Great Britain is 17/99.

Step-by-step explanation:

The table is given below:

$\left|\begin{array}{l|c|c|c|c|c} &Gold&Silver & Bronze &Total\\United States &46 & 29 & 29 & 104\\China & 38 & 27 & 23 & 88\\Russia & 24 & 26 & 32 &82\\Great Britain & 29 & 17 & 19 & 65\\&&&&&\\Total &137 & 99 & 103 & 339\end{array}\right$

We calculate the probabilities given in the statements.

(A) The probability that a randomly selected silver medal was awarded to Great Britain

= 17/99

(B)The probability that a randomly selected medal won by Russia was a bronze medal

=32/82

(C)The probability that a randomly selected gold medal was awarded to China

=38/137

(D)The probability that a randomly selected medal won by the United States was a silver medal

=29/104

We can see that only the first statement is true.

For any positive integers a and b, the operation ⓧ is defined as aⓧb=(2a-1)^b-1. what is the value of (2ⓧ2)ⓧ3?

m_a_m_a [10]

If the definition of $\otimes$ is $a\otimes b=(2a-1)^{b-1}$ , then

$2\otimes2=(2\cdot2-1)^{2-1}=3^1=3$
$(2\otimes2)\otimes3=3\otimes3=(2\cdot3-1)^{3-1}=5^2=25$
