The possible values for the product [tex]\( a \cdot b \)[/tex] are between -14 and 14, inclusive.

Here's the step-by-step calculation:

1. To find the minimum possible value, we multiply the smallest values of ( a ) and ( b ):

[tex]\( a = -5 \) and \( b = -7 \)[/tex]

[tex]\( a \cdot b = (-5) \cdot (-7) = 35 \)[/tex]

2. To find the maximum possible value, we multiply the largest values of ( a ) and ( b ):

[tex]\( a = 2 \) and \( b = 1 \)[/tex]

 [tex]\( a \cdot b = 2 \cdot 1 = 2 \)[/tex]

So, the possible values for the product[tex]\( a \cdot b \)[/tex]  are between -14 and 14.

The range of values for( a ) is from -5 to 2, and for ( b ) is from -7 to 1. To find the extreme values of the product [tex]\( a \cdot b \),[/tex]  we multiply the smallest and largest values of ( a ) and ( b ).

For the minimum value, we take ( a = -5 ) and ( b = -7 ), which gives us [tex]( a \cdot b = 35 \).[/tex]

For the maximum value, we take ( a = 2 ) and ( b = 1 ), which gives us [tex]\( a \cdot b = 2 \).[/tex]

Therefore, the product[tex]\( a \cdot b \)[/tex] ranges from -14 to 14, inclusively.

Answer:  Each friend get 3.5 cookies.

Step-by-step explanation:  Given that two friends share 7 cookie equally.

We are to find the number of cookies that each friend get.

We will be using the UNITARY method to solve the given problem.

Number of cookies shared by 2 friends equally = 7.

Therefore, number of cookies that one friend get will be

[tex]\dfrac{7}{2}=3.5.[/tex]

Thus, each friend get 3.5 cookies.

Answer:  The required number of brushes that each student receive is 12.

Step-by-step explanation:  Given that an  art teacher has 40 paint brushes.she divides them equally among her 4 students.

She finds 8 more brushes and divides these equally among the students, as well.

We are to find the number of brushes that each student receive.

The total number of brushes that divides among the 4 students is

[tex]n=40+8=48.[/tex]

Since there were 4 students, so the number of brushes that each student receive is

[tex]n_b=\dfrac{n}{4}\\\\\\\Rightarrow n_b=\dfrac{48}{4}\\\\\Rightarrow n_b=12.[/tex]

Thus, the required number of brushes that each student receive is 12.

The coordinates of the image of triangle ABC are A''(4, -2), B''(2, 1) and C''(-2, -2).

Here are the rotation rules: 90° clockwise rotation: (x, y) becomes (y, -x) 90° counterclockwise rotation: (x, y) becomes (-y, x).

Given that, he vertices of a triangle are A(-2,4), B (1,2), and C(-2,-2).

Reflect the triangle in the y-axis

The rule for a reflection over the y -axis is (x,y)→(-x, y)

Here, A(-2, 4)→A'(2, 4)

B (1,2)→B'(-1, 2)

C(-2,-2)→C'(2, -2)

Then rotate the image 90 degrees counterclockwise about the origin.

A'(2, 4)→A''(4, -2)

B'(-1, 2)→B''(2, 1)

C'(2, -2)→C''(-2, -2)

Therefore, the coordinates of the image of triangle ABC are A''(4, -2), B''(2, 1) and C''(-2, -2).

Final answer:

The approximate mean score for all the students on the quiz, calculated by weighing the means by the number of students in each section, is 85.71, which rounds to 86. Thus, the best answer choice (B)  from those provided is 85.

Explanation:

To find the overall mean score for all the students on the quiz, we need to weigh the mean scores by the number of students in each section. We do this by multiplying each section's mean score by the number of students in that section, then adding these products together, and dividing by the total number of students.

For Section A: 15 students × mean score of 80 = 1200 total points.
For Section B: 20 students × mean score of 90 = 1800 total points.

The total points for both sections is 1200 + 1800 = 3000 points.

The total number of students is 15 + 20 = 35 students.

To find the overall mean, we divide the total points by the total number of students:
3000 total points ÷ 35 students = approximately 85.71.

Therefore, the approximate mean score for all the students on the quiz is 85.71, which, when rounded to a whole number, is 86. The closest answer choice given is B. 85, so that would be the best selection from the available options.

Answer:

23 is the required answer.

Step-by-step explanation:

We are given a fraction of the form [tex]2\frac{5}{9}[/tex].

It is a mixed fraction.

We convert it into improper fraction.

The improper fraction is of the form [tex]\frac{(9\times2)+5}{9} = \frac{23}{9}[/tex].

This fraction can also be written as 23 multiplied [tex]\frac{1}{9}[/tex] times.

It is clear that the above fraction have 23 parts of ninth.

Answer: 55%

Work:

99 + 121 = 220

121 / 220 = 0.55 = 55%

The lower bound of the width of the rectangle is 19.35 mm. Without the length, we cannot determine the exact lower bound for the area of the rectangle. However, if we know the length, we can calculate it by multiplying the length by 19.35 mm.

The lower bound of the width of the rectangle, measured to one decimal place, is slightly less than the measured value. Thus, the lower bound of the width would be 19.35 mm (since we are accurate to 1 decimal place). However, without information about the length of the rectangle, we cannot exactly determine the lower bound of the area of the rectangle.

But if we assume the length to be a certain value (let's say 'L'), the lower bound for the area (A) would be the product of this length and the lower bound of the width. So,

A = L*19.35 mm.

The solution to the equation -15 = -4m + 5 is m = 5.

We have,

To solve the equation -15 = -4m + 5, you can follow these steps:

- Step 1:

Start by isolating the variable term (-4m) on one side of the equation.

You can do this by subtracting 5 from both sides:

-15 - 5 = -4m

Simplifying, we get:

-20 = -4m

Step 2:

Divide both sides of the equation by -4 to solve for m:

-20 / -4 = -4m / -4

Simplifying, we get:

5 = m

Therefore,

The solution to the equation -15 = -4m + 5 is m = 5.

There are 3 extra pallets will be there.

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example,Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

We have.

The warehouse already has 27 pallets of stock waiting to be unloaded, and the delivery van arrives with another 8.

After discarding the gold card, Carolee has a total of 10 cards left. The calculation for the percentage of red cards among these is (3 red cards / 10 total cards) × 100, resulting in 30% of the remaining cards being red.

The question asks about the percentage of the remaining cards that are red after Carolee discards the gold card. Initially, Carolee has 4 green cards, 3 red cards, 3 orange cards, and 1 gold card. After discarding the gold card, she has a total of 10 cards left (4 green + 3 red + 3 orange).

To find the percentage of the remaining cards that are red, we use the formula for percentage, which is (Part / Whole) × 100. In this case, the 'part' is the number of red cards, and the 'whole' is the total number of remaining cards.

Percentage of red cards = (Number of red cards / Total number of cards) × 100

= (3 / 10) × 100

= 30%

Therefore, 30% of Carolee's remaining cards are red.

Step-by-step explanation:

Given: [tex]6\times (12-4)[/tex]

To write the given expression in words.

"6 times the difference of 12 and 4"

Because difference of 12 and 4 is 12-4

6 times of a number(n) is 6n

Therefore,

[tex]6\times (12-4)[/tex] as phrase "6 times the  difference of 12 and 4"

Hence, The phrase of the given expression is "6 times the  difference of 12 and 4"

Option A is correct. The equivalent expression is −2.1−(5.9+3.7)

Given the expression −2.1+(−5.9)+(−3.7)

Before we can determine the equivalent expression, we need to first know that:

The given expression then becomes;

−2.1+(−5.9)+(−3.7) = -2.1 - 5.9 - 3.7

Factoring out the negative sign from the last two terms;

 -2.1 - 5.9 - 3.7 =  -2.1 - (5.9 + 3.7)

Hence the equivalent expression is −2.1−(5.9+3.7)

The x-intersection of y=4x+8 is at the point (-2,0) and the y-intersection is at the point (0,8).

We want to find the points where the line y=4x+8 intersects the x and y-axis.

For the x-intersection, we set y=0.

So, 0=4x+8, which simplifies to x = -2. So, the x-intersection is at the point (-2,0).

For the y-intersection, we set x=0.

So, y=4*0+8, which gives y = 8. So, the y-intersection is at the point (0,8).

To find the x-intercept, set y=0 and solve for x:

0 = 4x + 8

x = -2

So, the x-intercept is (-2, 0).

To find the y-intercept, set x=0 and solve for y:

y = 4(0) + 8

y = 8

So, the y-intercept is (0, 8).
