Answer:

a) 15 is the largest number of groups that can be made.

b) There would 6 sixth grade students and 5 seventh grade students in each group.

Step-by-step explanation:

Number of sixth-grade students = 90

Number of seventh-grade students = 75

a) What is the largest number of groups that could be formed?

Since the music director wants to make groups with the same combination of sixth and seventh grade students in each group,

The greatest common factor (GCF) of the number of sixth and seventh grade students would give us the required combination.

Factor of 90 = 2*45 = 2*3*15 = 2*3*3*5

Factor of 75 = 3*25 = 3*5*5

The greatest common factors are 3 and 5

GCF = 3*5 = 15

Therefore, 15 is the largest number of groups that can be made.

b. If that many groups are formed, how many students of each grade level would be in each group?

Sixth grade = 90/15 = 6

Seventh grade = 75/15 = 5

Therefore, there would 6 sixth grade students and 5 seventh grade students in each group.

1. 15 groups. The greatest common factor of 75 and 90 is 15. 2. 6 sixth-grade students and 5 seventh-grade students

2. 6 sixth-grade students and 5 seventh-grade students ( 6 ⋅ 15 = 90 and

5 ⋅ 15 = 75 )

Answer:

(x-10) (x+8)

Step-by-step explanation:

x^2 – 2x – 80.

What two numbers multiply to -80 and add to -2

-10*8 = -80

-10+8 = -2

(x-10) (x+8)

=====================================================

Explanation:

The last term is -80 and the middle coefficient is -2

Find two numbers that

Those two numbers are 8 and -10

which is why the original expression factors to (x+8)(x-10)

We can use the FOIL rule to expand out (x+8)(x-10) to end up with x^2-10x+8x-80 = x^2-2x-80, which confirms we have the correct factorization. You can use the box method as an alternative.

Answer: Todd earned $40 mowing the neighbor's lawn.

Step-by-step explanation:

Let x represent the amount of money that Todd earned, mowing his neighbor's lawn.

He spent one-fourth of his money see a movie. It means that the amount spent in seeing a movie is x/4

Then he spent $6.00 on popcorn and drinks. It means that the total amount spent is

x/4 + 6

The amount left would be

x - (x/4 + 6) = x - x/4 - 6

When he went home, he had $24.00 left. It means that

x - x/4 - 6 = 24

x - x/4 = 24 + 6

x - x/4 = 30

Cross multiplying by 4, it becomes

4x - x = 120

3x = 120

x = 120/3

x = $40

Answer:

[tex]9x^2+12x[/tex]

Step-by-step explanation:

Height of the Rectangle =3

Width of the Rectangle =[tex]3x^2+4x[/tex]

Area of a Rectangle = Height X Width

[tex]=3(3x^2+4x)\\=9x^2+12x[/tex]

The area of the rectangle is therefore given by:

[tex]9x^2+12x[/tex]

To find the area of the rectangle, multiply its height by its width. In this case, expand the expression for the width by distributing the terms. Simplify and combine like terms to get the expanded expression for the area: 999x^4 + 36x^3 + 16x.

To find the area of a rectangle, we multiply its length (height) by its width. In this case, the height is given as 333 and the width is given as 3x^2 + 4x3x^2 + 4x3x, x^2 + 4, x. To expand this expression and find the area, we can distribute the numbers/variables inside the parentheses.

We have (3x^2 + 4x3x^2 + 4x3x) * (x^2 + 4x). Distributing the terms inside, we get 3x^2 * x^2 + 3x^2 * 4x + 4x3x^2 * x^2 + 4x3x^2 * 4x + 4x3x * x^2 + 4x3x * 4x. Simplifying further, we have 3x^4 + 12x^3 + 4x^4 + 16x^3 + 4x^3 + 16x.

The area of the rectangle is the product of the height and width, so the expanded expression for the area is (333) * (3x^4 + 12x^3 + 4x^4 + 16x^3 + 4x^3 + 16x). Combining like terms, we have 999x^4 + 36x^3 + 16x. This is the expanded expression for the area of the rectangle.

Question:

A. The middle 95% of Jiffy Corn Muffin Mix boxes contain between _____ and ________ounces of cereal

Answer:

Therefore the middle 95% of Jiffy Corn Muffin Mix boxes contain between _9.994____ and _10.0062_______ounces of cereal

Step-by-step explanation:

The question requires us to construct the 95% confidence interval of the normal distribution as follows;

The mean, μ = 10

The sample standard deviation, σ = 0.1

Assumption

Number of boxes, n = 1000

The formula for confidence interval is as follows;

[tex]CI= \mu \pm z\frac{\sigma}{\sqrt{n}}[/tex]

Where, z at 95% confidence level is given as ±1.96

Plugging in the values, we have;

[tex]CI=10 \pm 1.96 \times \frac{0.1}{\sqrt{1000}}[/tex]

Therefore the middle 95% of Jiffy Corn Muffin Mix boxes contain between _9.994____ and _10.0062_______ounces of cereal.

If the experiment is repeated with 50 spins, the prediction for the number of spins that will land on green is 5

From the question, we have the following parameters that can be used in our computation:

The table of values

Calculate the total number of spins

So, we have

Total spins = 5  + 3 + 1 + 1

Total spins = 10

We have that

The frequency of landing on green is 1

The experimental probability of landing on green is then represented as

[tex]\[ \text{Probability of green} = \frac{1}{10} \][/tex]

Using the experimental probability to predict the number of spins that will land on green in 50 spins, we have

Predicted number of green spins = [tex]\frac{1}{10} \times 50 = 5[/tex]

So, if the experiment is repeated with 50 spins, the prediction for the number of spins that will land on green is 5

Answer: L(t)= 7600 times 5^t/22

Step-by-step explanation:

kahn answer

To model the locust population, we can use an exponential growth function. The initial population is given as 7600, and it increases by a factor of 555 every 222222 days. The function is L(t) = 7600 * 555^(t/222222).

To model the locust population, we can use an exponential growth function. The initial population is given as 7600. The population increases by a factor of 555 every 222222 days. Let's denote the time since the first day of spring as t. The function can be written as:

L(t) = 7600 * 555^(t/222222)

For example, if we want to find the locust population after 1 year (365 days), we can substitute t = 365 into the function:

L(365) = 7600 * 555^(365/222222)

By evaluating this expression, we can determine the locust population at any given time since the first day of spring.

Final answer:

The probability of capturing a green sea turtle considered illegal due to its size is about 45.52%. This is calculated using Z-scores and probabilities from the normal distribution, given the mean turtle size and standard deviation.

Explanation:

In the scenario provided, the probability of capturing a green sea turtle that is considered illegal (outside the 40cm to 60cm size limits) can be determined using normal distribution calculations. Given that the curved carapace length of these turtles is approximately normally distributed with a mean of 55.7 centimeters and a standard deviation of 12 cm, we will calculate the Z-scores for both size limits and then find the corresponding probabilities.

The Z-score formula is: Z = (X - μ)/σ, where X is the value in question, μ is the mean, and σ is the standard deviation. For the minimum size limit (40cm), Z = (40 - 55.7)/12 = -1.308. For the maximum size limit (60cm), Z = (60 - 55.7)/12 = 0.358.

Using standard normal distribution tables or a calculator, we find the probability corresponding to the Z-score of -1.308 and 0.358. The area to the left of Z = -1.308 is approximately 0.0951, and to the left of Z = 0.358 is approximately 0.6399. The probability of catching an illegal turtle is the sum of the probabilities of catching one smaller than 40cm and one larger than 60cm, which is P(X < 40) + P(X > 60) = 0.0951 + (1 - 0.6399) = 0.0951 + 0.3601 = 0.4552, or 45.52%.

Answer:

  C)  y = (1/4)^(-x)

Step-by-step explanation:

The average rate of change on an interval [a, b] is found using the formula ...

  arc = (f(b) -f(a))/(b -a)

For an exponential function with base b on interval [2, 3], the rate of change is ...

  arc = (b^3 -b^2)/(3 -2) = b^2(b -1)

This expression assumes a positive sign on the exponent.

We can compute the arc for each answer choice as ...

  (reference) 1/3^-x = 3^x ⇒ arc = 3²(3 -1) = 18

  A) 2^x ⇒ arc = 2²(2 -1) = 4

  B) 5^(x-2) = (1/25)5^x ⇒ arc = (1/25)(5²)(5 -1) = 4

  C) 1/4^-x = 4^x ⇒ arc = 4²(4 -1) = 48

  D) (2/3)^-x = (3/2)^x ⇒ arc = (3/2)²(3/2 -1) = 9/8

An average rate of change greater than 18 is demonstrated by (1/4)^-x.

The required probability of the selected letter was either an a or an n is 0.5.

Given that,

One letter was selected at random from the words San Antonio.  The probability that the selected letter was either an a or an n is to be determined.

Probability can be defined as the ratio of favorable outcomes to the total number of events.

Here,
Total letters = 10
Total a and n = 2 and 3
The probability is given as = 2 / 10 + 3 / 10
                                            = 5/10 = 1/2 = 0.5

Thus,  the required probability of the selected letter was either an a or an n is 0.5.

(These values are the same as in the given matrix)

=======================================================

Explanation:

Row echelon form will have us turn the "3" into a 0. To do this, we multiply everything in row 1 by the value -3

Row 1 is initially: 1, -4, 3

Multiply that row by -3 to get: -3, 12, -9

Then add these values to the values in row 2 and we get:

-3+3 = 0

12+1 = 13

-9+0 = -9

These three sums replace what you see in row 2

This is the new matrix we have now

[tex]\left[\begin{array}{ccc}1 & -4 & 3\\0 & 13 & -9\end{array}\right][/tex]

Again the first row has not changed. Only the second row has been altered.

The next and last step is to turn that 13 into a 1. Recall we want the pivot positions to be 1. Divide everything in row 2 by 13 to get this accomplished.

0---> 0/13 = 0

13 ----> 13/13 = 1

-9 ---> -9/13

we now have

[tex]\left[\begin{array}{ccc}1 & -4 & 3\\0 & 1 & \frac{-9}{13}\end{array}\right][/tex]

We stop here since we don't need to get the matrix into reduced row echelon form (RREF) and instead only need to get it into row echelon form (REF). Throughout this whole process, row 1 has not changed.

Answer:

0.363

Step-by-step explanation:

Number of Black(B) Socks =5

Number of Grey(G) Socks =7

Number of White(W) Socks =13

Total Number of Socks=5+7+13=25

If the two socks are picked one after the other, the total number reduces and the number of that particular color of socks picked also reduces.

To pick the same color, they could either be both black, grey of white.

Therefore:

P(they are of the same color)=P(BB)+P(GG)+P(WW)

[tex]=(\frac{5}{25}X\frac{4}{24})+(\frac{7}{25}X\frac{6}{24})+(\frac{13}{25}X\frac{12}{24})\\=0.363[/tex]

The probability that they are of the same color is 0.363 correct to 3 significant figures.

Answer: it will take 9 hours to empty the pool.

Step-by-step explanation:

The pool is shaped like a rectangular prism with length 30 feet, wide 18 ft, and depth 4ft. It means that when the pool is full, its volume is

30 × 18 × 4 = 2160 ft³

If water is pumped out of the pool at a rate of 216ft3 per hour, then the rate at which the water in the pool is decreasing is in arithmetic progression. The formula for determining the nth term of an arithmetic sequence is expressed as

Tn = a + d(n - 1)

Where

a represents the first term of the sequence(initial amount of water in the pool when completely full).

d represents the common difference(rate at which it is being pumped out)

n represents the number of terms(hours) in the sequence.

From the information given,

a = 2160 degrees

d = - 216 ft3

Tn = 0(the final volume would be zero)

We want to determine the number of terms(hours) for which Tn would be zero. Therefore,

0 = 2160 - 216 (n - 1)

2160 = 216(n - 1) = 216n + 216

216n = 2160 - 216

216n = 1944

n = 1944/216

n = 9

Step-by-step explanation:

Answer: it will take 9 hours to empty the pool. Step-by-step explanation: The pool is shaped like a rectangular prism with length 30 feet, wide 18 ft, and depth 4ft.

From the information given, a = 2160 degrees 216 ft3 d = Tn = 0(the final volume would be zero) We want to determine the number of terms(hours) for which Tn would be zero.

We want to determine the number of terms(hours) for which Tn would be zero. Therefore,

O = 2160 - 216 (n - 1) 2160 = 216(n - 1) = 216n + 216 216n = 2160 - 216 216n = 1944 %3D n = 1944/216 n = 9

Answer:

y = 1/4x -8

Step-by-step explanation:

First find the slope of the line

x-4y =3

Subtract x from each side

x-4y -x = -x+3

-4y = -x+3

Divide each side by -4

-4y/-4 = -x/-4 +3/-4

y = 1/4 x -3/4

This is in the form y= mx+b where the slope is m and the y intercept is b

The slope is 1/4

We want the same slope

y = 1/4x +b

we know the y intercept is -8

y = 1/4x -8
