There are 126 different selections possible if at least 3 balls must be blue.

Total number of red balls: 8

Total number of blue balls: 8

Also, a woman selects 4 balls

And also at least 3 balls off the 4 must be blue

So the first combination is 3 blue and 1 red remember the woman picks up 4 balls.

And the second combination is 4 blue and 0 Red remember at least 3 blue balls

So the equation is as given below:

\(^nC_{r} =\frac{n(n-1)(n-2)(n-3)..... r terms.}{1*2*3..... r terms.}\)

Now substitute values in the formula:

(8C3*8C1 + 8C4*8C0)=(56+70)=126 selections.

Hence, There are 126 different selections are possible if at least 3 balls must be blue.

The values we can choose in each region to make the inequalities true are: Leftmost region: (0,3) , Middle region: (2,2) and Rightmost region: (3,0)

what is inequality ?

In mathematics, inequality refers to a relationship between two values or expressions that are not equal. In an inequality, one value or expression is greater than, less than, or greater than or equal to, less than or equal to the other value or expression.

To provide a value in each region that makes the inequality or inequalities true, we need to consider the boundary lines of each region and the signs of the inequalities.

Starting with the leftmost region, we have the boundary lines x = -1 and y = 2. The inequality is x < -1 OR y > 2. To make this true in the leftmost region, we can choose any point that satisfies either x < -1 or y > 2. For example, (0,3) would work.

Moving to the middle region, we have the boundary lines y = x and y = -x + 4. The inequality is y > x AND y < -x + 4. To make this true in the middle region, we need to choose a point that satisfies both inequalities. One such point is (2,2).

Finally, in the rightmost region, we have the boundary lines y = 1 and y = -x + 4. The inequality is y < 1 AND y < -x + 4. To make this true in the rightmost region, we need to choose a point that satisfies both inequalities. For example, (3,0) would work.

Therefore,  the values we can choose in each region to make the inequalities true are: Leftmost region: (0,3) , Middle region: (2,2) and Rightmost region: (3,0)

The simplified expression when q = −9, r = 4, and s=8 is -63. The given expression is -5r - 2s + 3q.

To simplify the expression when q = −9, r = 4, and s=8, we substitute the values of q, r, and s into the expression to get:

-5(4) - 2(8) + 3(-9)

This simplifies to:

-20 -16 -27 = -63

Therefore, the simplified expression when q = −9, r = 4, and s=8 is -63.

In general, when simplifying expressions, it is important to remember the order of operations: parentheses, exponents, multiplication and division (from left to right), and addition and subtraction (from left to right). It is also important to keep track of any negative signs, as they can affect the final result.

Simplifying expressions can be useful in many situations, such as solving equations or evaluating functions. In this case, knowing the simplified expression allows us to quickly evaluate it for different values of q, r, and s without having to repeat the same calculations over and over again.

Step-by-step explanation:

The graph has y-intercept (0,5) and increases with a constant ratio of 3.

A function in mathematics is a connection between a set of inputs (sometimes referred to as the domain) and a set of outputs (also referred to as the range). Each input value is given a different output value.

The y-intercept lies at (0, 5) because the value of the function at x=0 is 530 = 5. The 'constant ratio' is 3, meaning that any increment of 1 in x causes the function value to grow by a factor of 3. (That serves as the exponential term's foundation.)

The surface area of the cylinder is approximately 339.292 square feet.

What is cylinder?

A cylinder is a three-dimensional geometric shape that consists of two parallel, congruent circular bases and a curved lateral surface that connects the two bases.

The formula for the surface area of a cylinder is:

SA = 2πrh + 2π\(r^2\)

where r is the radius of the base, h is the height of the cylinder, and π is the mathematical constant pi.

Substituting the given values, we get:

SA = 2π(6)(3) + 2π\((6)^2\)

SA = 2π(18) + 2π(36)

SA = 36π + 72π

SA = 108π

To round the answer to the nearest thousandth, we need to evaluate 108π and approximate it to three decimal places using a calculator or by estimating π as 3.14159. Therefore:

SA ≈ 108π ≈ 339.292 \(ft^2\)

Thus, the surface area of the cylinder is approximately 339.292 square feet.

The inequality that shows the result of solving -ax/b > c - d for x is x < (b(c - d)) / a. To solve the inequality -ax/b > c - d for x, we'll perform some algebraic manipulations. Here's the step-by-step process:

Multiply both sides of the inequality by b to eliminate the denominator:

-ax > b(c - d)

Divide both sides by -a. Since a is positive, the direction of the inequality will flip:

x < (b(c - d)) / -a

Note: When dividing by a negative number, the inequality direction is reversed.

However, we want to express the result in terms of a positive coefficient for x. To achieve this, we can multiply both sides of the inequality by -1:

-x > -((b(c - d)) / a)

Finally, multiplying both sides by -1 again will reverse the inequality direction:

x < (b(c - d)) / a

Answer: The explicit formula for a geometric sequence is given by:

an = a1 * r^(n-1)

Where a1 is the first term, r is the common ratio, and n is the term number.

Part A) In this sequence, the first term is 4, and the common ratio is 4/1 = 4.

So the explicit formula for this sequence is:

an = 4 * 4^(n-1)

To find the 8th term of this sequence, we can substitute n = 8 into the formula:

a8 = 4 * 4^(8-1)

a8 = 4 * 4^7

a8 = 4 * 16,384

a8 = 65,536

Answer:

The equation of the line with a y-intercept of 2 and an x-intercept of -3 can be written in slope-intercept form as: y = mx + b, where m is the slope and b is the y-intercept.

The y-intercept is given as 2, so b = 2.

To find the slope, we can use the formula:

m = (y2 - y1) / (x2 - x1)

Using the x-intercept (-3, 0) and the y-intercept (0, 2), we get:

m = (2 - 0) / (0 - (-3)) = 2/3

So the equation of the line is: y = (2/3)x + 2.

None of the given options match this equation, so the answer is none of the above.

The percentage of graduating classes had taken fewer than 6 math classes is 10%.

In essence, percentages are fractions with 100 as the denominator. To show that a number is a percentage, we place the percent sign (%) next to it. For instance, you would have received a 75% grade if you answered 75 out of 100 questions correctly on a test (75/100).

Given that this year 75% of the graduating class has taken at least 8 math classes. of the remaining class members, 60% had taken 6 or 7 math classes

75 % took at least 8 math courses

of the remaining class members( 25 % remain ),

60 % took 6 or 7 math courses, thus 60 % of 25 % is

0.6x25 %=15 % took 6 or 7 math courses

so 75 % took 8 or more math courses, 15 % took 6 or 7 math courses, therefore that leaves 10 % taking fewer than 6 math courses ( 75 %+15 %=90 %, 100 %-90 %=10 %)

Therefore the percentage of graduating class who had taken fewer than 6 math classes is 10%.

Answer:

The equation that describes the profit the store makes in a day that X units of yo-yo is sold is  P= X × $8.00 - $50.00

Step-by-step explanation:

The information given are;

The price of each yo-yo = $8.00

The only available cost is the store clerk fee cost per day = $50.00

Let us call the number of yo-yo's sold per day as X

Therefore, the amount sold per day = X × $8.00

The company's profit, P = Total sales - Total cost

∴ P= X × $8.00 - $50.00

Therefore, the equation that describes the profit the store makes in a day that X units of yo-yo is sold = P= X × $8.00 - $50.00.

The 90% confidence interval for a population proportion with n=570 and p'=0.65 is 0.616 < p < 0.684.

To construct a confidence interval for a population proportion, we can use the formula:

p ± z*sqrt(p'(1-p')/n)

where p' is the sample proportion, n is the sample size, and z is the z-score corresponding to the desired level of confidence.

In this case, we have n=570 and p'=0.65. We need to find the value of z that corresponds to a 90% confidence level. We can use a table of standard normal probabilities or a calculator to find that z=1.645.

Substituting the values into the formula, we get:

p ± 1.645*sqrt(0.65(1-0.65)/570)

Simplifying, we get:

p ± 0.042

Therefore, the 90% confidence interval is:

0.65 - 0.042 < p < 0.65 + 0.042

0.608 < p < 0.692

Rounding to three decimal places, we get:

0.616 < p < 0.684.
