Both classes plan extracurricular activities for which each class forms a committee consisting of three students. How many possible committees are there such that the total of committee members of both classes combined consists of 4 girls

Answer:

Nathan

Step-by-step explanation:

Because 4.76 ÷ 2.5 is 1.904

Nathan is correct about the decimal being misplaced in the quotient. The correct division of 4.76 by 2.5 should give 1.904 when rounded off to two decimal places.

In this case, Nathan is correct in stating that the decimal is misplaced in the quotient. When rounding to two decimal places, the correct calculation should be 4.76 ÷ 2.5 = 1.904, not 0.19. The decimal point division process can be simplified as follows:

Another approach would be to simply use a calculator to confirm the correct division of 4.76 by 2.5.

Answer:

20, 40, and 120

Step-by-step explanation:

x, 2x, and 6x have one thing in common: X. X is the same number throughout so if we find x we can just finish the equation by multiplying x by its coefficient.

x+2x+6x = 180. (Sum of angle measures)

9x           = 180 (Add up the left side)

9x/9        = 180/9 (Divide both sides by 9 to cancel out the 9 and leave the x)

x              = 20

Now we know what x is so:

Angle 1 = 20. (We know x is 20, so that one is easy.)

Angle 2 = 40 (Simply 2*x or 2*20)

Angle 3 = 120 (Simply 6*x or 6*20)

Answer: 67.

Step-by-step explanation: To find the range of a set of numbers, all you have to do is subtract the smallest number in the set from the largest number. In this case, the smallest number would be 7 and the largest number would be 74. 74 - 7 equals 67, and so the range is 67.

Final answer:

The range is the difference between the largest and smallest numbers in the set. For the numbers 66, 8, 12, 74, 36, 66, 7, the range is 67.

Explanation:

The range of a set of numbers is the difference between the largest and smallest numbers in the set. To find the range of the numbers 66, 8, 12, 74, 36, 66, 7, you would first identify the smallest and largest number, which are 7 and 74, respectively. Then, subtract the smallest number from the largest number: 74 - 7 = 67.

Therefore, the range of the set of numbers is 67.

Data is distinct pieces of information, usually formatted in a special way.

Step-by-step explanation:

Answer:

(a) 45 miles

(b) 38 miles

(c) Jada travels faster than Andre.

Step-by-step explanation:

(a) First we calculate the speed at which Jada travelled:

[tex]Speed = \frac{distance}{time} \\\\\\s = \frac{d}{t}[/tex]

[tex]s = \frac{135}{3} \\\\\\s = 45 miles/hour[/tex]

Since Jada travels at constant speed throughout the journey, we can calculate the distance traveled in 1 hour:

[tex]distance = speed * time\\\\\\distance = 45 * 1[/tex]

distance = 45 miles

Jada travels 45 miles in 1 hour.

(b) We calculate the speed at which Andre travelled:

[tex]Speed = \frac{distance}{time} \\\\\\s = \frac{d}{t}[/tex]

[tex]s = \frac{228}{6} \\\\\\s = 38 miles/hour[/tex]

Since Andre travels at constant speed throughout the journey, we can calculate the distance traveled in 1 hour:

[tex]distance = speed * time\\\\\\distance = 38 * 1[/tex]

distance = 38 miles

Andre travels 38 miles in 1 hour.

(c) Jada travels faster than Andre because he has a higher speed (45 miles/hour) than Andre ( 38 miles/hour).

Answer: The probability that a randomly selected teacher will make more than $40,542 per year is 0.82

Step-by-step explanation:

Looking at the information given, the population mean and population standard deviation are known. We would apply the formula

z = (x - µ)/σ

Where

x = sample mean

µ = population mean

σ = population standard deviation

From the information given,

µ = $42335

σ = 2000

x = $40542

The probability that a randomly selected teacher will make more than $40,542 per year is expressed as

P(x > 40542) = 1 - P(x ≤ 40542)

For P(x ≤ 40542),

z = (40542 - 42335)/2000 = - 0.9

Looking at the normal distribution table, the probability corresponding to the z score is 0.18

P(x > 40542) = 1 - 0.18 = 0.82

Step-by-step explanation:

48*5=240

The actual straight-line distance between New York City (NYC) and Boston is calculated by multiplying the map distance of 5 inches by the scale factor of 48 miles per inch, resulting in 240 miles.

The question involves finding the actual distance between New York City (NYC) and Boston based on a map scale. The given scale is 1 inch to 48 miles, and the map shows a distance of 5 inches between the two cities.

To calculate the actual distance, we use the scale factor. Multiply the map distance by the scale factor:

Map distance between NYC and Boston: 5 inches

Scale factor: 1 inch equals 48 miles

Actual distance calculation: 5 inches x 48 miles per inch = 240 miles

Therefore, the actual straight-line distance between New York City and Boston is 240 miles.

Answer:

64°

Step-by-step explanation:

In circle with center P, AD is diameter.

[tex] \therefore m\angle DPE + m\angle APE = 180\degree \\

\therefore (33k-9)\degree + 90\degree = 180\degree \\

\therefore (33k-9)\degree = 180\degree -90\degree \\

\therefore (33k-9)\degree = 90\degree \\

\therefore 33k-9 = 90\\

\therefore 33k= 90+9\\

\therefore 33k= 99\\

\therefore k= \frac{99}{33}\\

\therefore k=3\\

m\angle CPD = (20k +4)\degree \\

\therefore m\angle CPD = (20\times 3 +4)\degree \\

\therefore m\angle CPD =(60+4)\degree \\

\therefore m\angle CPD =64\degree \\

m\overset {\frown}{CD} = m\angle CPD\\

\therefore m\overset {\frown}{CD} = 64\degree

Answer:

1/30 = 3.33%

Step-by-step explanation:

There are 3 different flavors available and the favorable outcome is only strawberry flavor. There are 10 toppings and the favorable outcome is sprinkle. To calculate the probability for the two events, you just need to multiply both. The calculation will be:

P(strawberry) * P(sprinkle) = 1/3 * 1/10= 1/30

The probability of the next customer ordering strawberry ice cream with sprinkles, given that there are 3 flavors and 10 toppings, is 1/30.

The student asks about the probability of a specific ice cream order at an ice cream shop, which involves both flavor selection and topping selection. Since there are 3 different flavors and 10 different toppings, we treat these choices as independent events. The probability of selecting strawberry ice cream is 1/3, as it is one of the three available flavors. The probability of selecting sprinkles as a topping is 1/10, since it is one of ten toppings. To find the total probability of both events occurring (strawberry ice cream with sprinkles), we multiply the two separate probabilities:

Probability = Probability of strawberry ice cream times Probability of sprinkles = 1/3 times 1/10 = 1/30.

The applicable rules of logarithms are ...

  log(ab) = log(a)+log(b)

  log(a^b) = b·log(a)

Final answer:

To expand the expression In 2a³/b⁴, you apply logarithm properties to obtain In 2 + 3 In a - 4 In b, which separates the factors into individual log terms.

Explanation:

The question asks us to expand the logarithmic expression In 2a³/b⁴ using logarithm properties. The correct expansion of this expression is given by the sum of the logarithms of the numerator's factors minus the sum of the logarithms of the denominator's factors. Applying the properties of logarithms (product to sum and quotient to difference), we obtain the expansion as follows:

In 2a³/b⁴ = In 2 + In a³ - In b⁴

The logarithm of a power (such as In a³ and In b⁴) can be brought down as a coefficient:

In 2 + 3 In a - 4 In b

Thus, the correct expansion is In 2 + 3 In a - 4 In b.

Answer:

B

Step-by-step explanation:

[tex]\frac{3.683 \times 10^4}{7.51 \times 10^{12}} \\=\frac{36.83 \times 10^3}{7.51 \times 10^{12}} \\=\frac{36.83}{7.51} \times 10^{3-12}\\ \approx 4.9041 \times 10^{-9}[/tex]

The quotient in the scientific notation form will be 4.9041 × 10⁻⁹. The correct option is B.

Scientific notation can be used to indicate numbers that are either too big or too little to be conveniently stated in decimal form. It may be called scientific form.

Standard notation is the practice of writing a number using nothing but its digits. This is how numbers are usually expressed because traditional number notation does not utilize words.

Given that the two numbers are (3.683 × 10⁴) and (7.51 × 10¹²). The quotient will be calculated as:-

Quotient = (3.683 × 10⁴) ÷ (7.51 × 10¹²)

Quotient = 0.49 x 10⁻⁸

Quotient = 4.9 x 10⁻⁹

The quotient will be 4.9041 × 10⁻⁹.
