The probability of being dealt a 9, 10, jack, queen, king, all in the same suit is 0.000154%.

Dealing 5 cards from a standard 52-card deck constitutes a specific type of event that can be explained using probability.

In order to calculate the probability of being dealt a 9, 10, jack, queen, king, all in the same suit, it is important to know the different card combinations that can occur during the experiment.
There are four suits in a standard 52-card deck: hearts, clubs, diamonds, and spades. Each suit has 13 cards, which are numbered 2 to 10, plus the ace, king, queen, and jack.
The probability of being dealt a 9, 10, jack, queen, king, all in the same suit is calculated using the following formula:
Number of ways to get a 9, 10, jack, queen, king, all in the same suit / Total number of possible 5-card hands
The number of ways to get a 9, 10, jack, queen, king, all in the same suit is calculated as follows:
There are 4 suits, and we need all five cards to be in the same suit. Therefore, there are 4 ways to choose the suit for the hand.
Once the suit is chosen, there are only 1 possible combination of cards that includes the 9, 10, jack, queen, and king.

Therefore, there is only 1 way to choose the actual cards for the hand.
The total number of possible 5-card hands is calculated using the formula:
52C5 = (52!)/((52-5)!5!) = 2,598,960
Therefore, the probability of being dealt a 9, 10, jack, queen, king, all in the same suit is:
4*1 / 2,598,960 = 0.000154%

Option (C) is the correct one and 4/x²√29 is the equivalent expression of 40x²√x^12 / 10x²√29x^8.

Given, an expression

40x²√x^12 / 10x²√29x^8, if x ≠ 0

On simplifying, we get

= 40x²x^6 / 10x²√29x^8

= (40/10)(x^8/x^8)(1/x²√29)

= 4/x²√29

So, on simplifying the given expression, we get

= 4/x²√29

Hence, Option (C) is the correct one and 4/x²√29 is the equivalent expression of 40x²√x^12 / 10x²√29x^8.

16,590 is the large sample needed to estimate the percentage of citizens in a certain town who favor having their water fluoridated if one wishes to be at least 99% confident that the estimate is within 1% of the true percentage.

In the given question,

At Washington University a conjecture by a faculty member in the microbiology department of dental medicine states that a couple of cups of either green or oolong tea each day will provide sufficient fluoride to protect your teeth from decay.

We have to find how large a sample is needed to estimate the percentage of citizens in a certain town who favor having their water fluoridated if one wishes to be at least 99% confident that the estimate is within 1% of the true percentage.

To find the sample size, we use the formula

n=0.25\((\frac{z_{\alpha /2}}{E})^2\)

Firstly we find the value of \(z_{\alpha /2}\)

The confidence interval is 99% or 0.99.

So \(\alpha\)=1−0.99

\(\alpha\)=0.01

So \(\alpha /2\) = 0.01/2 = 0.005

So using the standard value of z

\(z_{0.005}\) = 2.576

E = 0.01

Now putting the value

n=0.25\((\frac{{2.576}}{0.01})^2\)

n=0.25(6.636/0.0001)

n=0.25*66360

n=16,590

Hence, 16,590 is the large sample needed to estimate the percentage of citizens in a certain town who favor having their water fluoridated if one wishes to be at least 99% confident that the estimate is within 1% of the true percentage.

Henry opens a savings account with an annual interest rate of 4.5 percent. After a year, he gets $75,000 in payment. He made a deposit into the savings account of $72,831.68.

Here are the steps on how to calculate the amount Henry invested:

Convert the annual interest rate to a monthly rate.

\(\begin{equation}4.5\% \div 12 = 0.375\%\end{equation}\)

Calculate the number of years.

\(\begin{equation}\frac{18 \text{ months}}{12 \text{ months/year}} = 1.5 \text{ years}\end{equation}\)

Use the compound interest formula to calculate the amount Henry invested.

\(\begin{equation}FV = PV * (1 + r)^t\end{equation}\)

where:

FV is the future value ($75,000)

PV is the present value (unknown)

r is the interest rate (0.375%)

t is the number of years (1.5 years)

\(\begin{equation}\$75,000 = PV \cdot (1 + 0.00375)^{1.5}\end{equation}\)

\$75,000 = PV * 1.0297

\(\begin{equation}PV = \frac{\$75,000}{1.0297}\end{equation}\)

PV = \$72,831.68

Therefore, Henry invested \$72,831.68 in the savings account.

Answer:

30%

Step-by-step explanation:

there are two numbers that fit in the x<=3 category, those being -3 and -5, so you add the two decimals for them (.17 and .13) to get .30 and move the decimal two times to the right to make it in percentage form.

The probability of P(x ≤ -3) is 0.30 or 30% if the probability table is provided.

It is defined as the ratio of the number of favourable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.

We have given a probability table in the picture.

P(x ≤ -3) = P(x = -5) + p(x = -3)

From the table:

P(x ≤ -3) = 0.17 + 0.13

P(x ≤ -3) = 0.30 or 30%

Thus, the probability of P(x ≤ -3) is 0.30 or 30% if the probability table is provided.

The value of pp when qq equals 2 is: 294

If pp is inversely proportional to the square of qq, it means that pp*qq²=k, where k is the constant of proportionality.

Given that pp is 24 when qq is 7, we can find the value of k:

24*7² = k

k = 1176

Now, we can use this value of k to find pp when qq is equal to 2:

pp*2² = 1176

pp*4 = 1176

pp = 1176/4

pp = 294

Therefore, when qq is equal to 2, pp is equal to 294.

The weight of the truck,  When a loaded truck pulls onto it, the boat sinks an additional 5.00cm into the river is  11,788 N.

To discover the weight of the truck, we ought to utilize the concept of buoyancy.

When the truck pulls onto the vessel, it uproots a sum of water that breaks even with its claimed weight. The weight of this uprooted water makes an upward buoyant constraint on the pontoon.

The watercraft sinks an extra 5.00 cm, which suggests that the buoyant constraint breaks even with the weight of the truck furthermore the weight of the uprooted water, and this adds up to the weight causing the boat to sink assist.

Let's accept that the thickness of water is 1000 kg/m³ (this can be ordinary esteem for new water). The volume of water uprooted by the pontoon is rise to its length times its width times the profundity it sinks into the water:

V = (6.00 m)(4.00 m)(0.05 m) = 1.20 m³

The weight of this uprooted water is:

Wwater = Vρg = (1.20 m³)(1000 kg/m³)(9.81 m/s²) ≈ 11,788 N

where ρ is the thickness of water and g is the speeding up due to gravity.

Since the buoyant drive is broken even with the weight of the truck furthermore the weight of the uprooted water, we have:

Wtruck + Wwater = Fbuoyant

where Wtruck is the weight of the truck and Fbuoyant is the buoyant drive. Ready to improve this condition to illuminate for the weight of the truck:

Wtruck = Fbuoyant - WWater

The buoyant drive is broken even with the weight of the water uprooted by the watercraft, which we calculated prior to being around 11,788 N. In this manner:

Wtruck = 11,788 N - 0

 Wtruck ≈ 11,788 N

So, the weight of the truck is around 11,788 N.

The events A and B are not mutually exclusive; not mutually exclusive (option b).

Explanation:

1st Part: Two events are mutually exclusive if they cannot occur at the same time. In contrast, events are not mutually exclusive if they can occur simultaneously.

2nd Part:

Event A consists of rolling a sum of 8 or rolling a sum that is an even number with a pair of six-sided dice. There are multiple outcomes that satisfy this event, such as (2, 6), (3, 5), (4, 4), (5, 3), and (6, 2). Notice that (4, 4) is an outcome that satisfies both conditions, as it represents rolling a sum of 8 and rolling a sum that is an even number. Therefore, Event A allows for the possibility of outcomes that satisfy both conditions simultaneously.

Event B involves drawing a 3 or drawing an even card from a standard deck of 52 playing cards. There are multiple outcomes that satisfy this event as well. For example, drawing the 3 of hearts satisfies the first condition, while drawing any of the even-numbered cards (2, 4, 6, 8, 10, Jack, Queen, King) satisfies the second condition. It is possible to draw a card that satisfies both conditions, such as the 2 of hearts. Therefore, Event B also allows for the possibility of outcomes that satisfy both conditions simultaneously.

Since both Event A and Event B have outcomes that can satisfy both conditions simultaneously, they are not mutually exclusive. Additionally, since they both have outcomes that satisfy their respective conditions individually, they are also not mutually exclusive in that regard. Therefore, the correct answer is option b: not mutually exclusive; not mutually exclusive.
