Answer:

1. Option C is correct.

2. Option D is correct.

3. Option A is correct.

4. Option A is correct.

Step-by-step explanation:

Starting and end point of box plot represent the minimum and maximum value respectively. Box starts from the first quartile to the third quartile. A vertical line goes through the box at the median.

From the given box plot we can conclude that

For Team A:

Minimum = 80,Q_1=87, median=91, Q_3=95,Maximum=110

For Team B:

Minimum = 79,Q_1=82, median=87, Q_3=91,Maximum=103

Formula for interquartile range.

IQR=Q_3-Q_1

1.

IQR of Team A.

IQR_{A}=95-87=8

Option C is correct.

2.

IQR of Team B.

IQR_{B}=91-82=9

Option D is correct.

3.

Difference of the medians of team A and team B is

91-87=4

Option A is correct.

4.

We know that 4 is about half of 8 and 9.

It means 4 is about half the interquartile range of either data set.

Option A is correct.

Geoffrey is evaluating the expression StartFraction (negative 3) cubed (2 Superscript 6 Baseline) Over (Negative 3) Superscript
makkiz [27]

The mathematical expression does not seem clear but I have made an attempt to make sense of what is implied.

Answer:

<em>a</em> = 4, <em>b</em> = 2, <em>c</em> = 16, <em>d</em> = 9

Step-by-step explanation:

\dfrac{(-3)^3(2^6)}{(-3)^5(2^2)} = \dfrac{(2)^a}{(-3)^b} = \dfrac{c}{d}

Solving the first part of the question by indices,

\dfrac{(-3)^3(2^6)}{(-3)^5(2^2)} = (-3)^{3-5}(2)^{6-2} = (-3)^{-2}(2)^{4} = \dfrac{(2)^4}{(-3)^2}

Comparing the rightmost term with the second term in the question,

<em>a</em> = 4, <em>b</em> = 2

Solving on,

\dfrac{(2)^4}{(-3)^2} = \dfrac{(2)\times(2)\times(2)\times(2)}{(-3)\times(-3)} = \dfrac{16}{9}

Comparing with the final term in the question,

<em>c</em> = 16 and <em>d</em> = 9

Therefore,

<em>a</em> = 4, <em>b</em> = 2, <em>c</em> = 16, <em>d</em> = 9

Jeanne wants to start collecting coins and orders a coin collection starter kit. The kit comes with three coins chosen at random
lesya692 [45]
Conditional probability is a measure of the probability of an event given that another event has occurred. If the event of interest is A and the event B is known or assumed to have occurred, "the conditional probability of A given B", or "the probability of A under the condition B", is usually written as P(A|B), or sometimes P_B(A).

The conditional probability of event A happening, given that event B has happened, written as P(A|B) is given by
P(A|B)= \frac{P(A \cap B)}{P(B)}

In the question, we were told that there are three randomly selected coins which can be a nickel, a dime or a quarter.

The probability of selecting one coin is \frac{1}{3}

Part A:
To find <span>the probability that all three coins are quarters if the first two envelopes Jeanne opens each contain a quarter, let the event that all three coins are quarters be A and the event that the first two envelopes Jeanne opens each contain a quarter be B.

P(A) means that the first envelope contains a quarter AND the second envelope contains a quarter AND the third envelope contains a quarter.

Thus P(A)= \frac{1}{3} \times \frac{1}{3} \times \frac{1}{3} = \frac{1}{27}

</span><span>P(B) means that the first envelope contains a quarter AND the second envelope contains a quarter

</span><span>Thus P(B)= \frac{1}{3} \times \frac{1}{3} = \frac{1}{9}

Therefore, P(A|B)=\left( \frac{ \frac{1}{27} }{ \frac{1}{9} } \right)= \frac{1}{3}


Part B:
</span>To find the probability that all three coins are different if the first envelope Jeanne opens contains a dime<span>, let the event that all three coins are different be C and the event that the first envelope Jeanne opens contains a dime be D.
</span><span>
P(C)= \frac{3}{3} \times \frac{2}{3} \times \frac{1}{3} = \frac{6}{27} = \frac{2}{9}

</span><span>P(D)= \frac{1}{3}</span><span>

Therefore, P(C|D)=\left( \frac{ \frac{2}{9} }{ \frac{1}{3} } \right)= \frac{2}{3}</span>

Gareth has $2,000 to invest. Putting the money in a savings account at his local bank will earn him 2.2% annual interest and giv
Alenkinab [10]

Answer:

Option c. 18 withdrawals is correct

Step-by-step explanation:

Gareth has to invest = $2,000

His local bank gives 2.2% annual interest and gives him the ability to make ATM withdrawals without any charges.

In an online savings gives 4.85% annual interest, but charges $3 every time he makes an ATM withdrawal.

Let us find the amount of interest earned from the local bank.

The amount of interest earned from Local Bank = 2.2% of 2000

= \frac{22}{100} × 2000

= 0.022 × 2000 = $44

The amount of interest earned from online savings = 4.85% of 2000

= \frac{4.85}{100} × 2000

= 0.0485 × 2000 = $97

As it is given that savings account has no ATM withdrawal charges but online savings account charge $3.00 per withdrawal.

so we  need to make x withdrawals from both accounts such that:

97 - 3x = 44

Let us solve for x.

Upon subtracting 97 from both sides of or equation we will get,

97 - 97 - 3x = 44 - 97

3x = -53

\frac{3x}{-3}=\frac{-53}{-3}

x = 17.666 rounded to 18

Therefore, Gareth must make 18 ATM withdrawals every year for the local savings account to be a better deal than the online savings account.
