There are 12 bags of apples on a market stall. The number of apples in bag 12 is 96.

The mean is the average value which can be calculated by dividing the sum of observations by the number of observations

Mean = Sum of observations/the number of observations

It is Given that, there are 12 bags of apples on a market stall.  

The mean number of apples in each bag is 8.  

We need to calculate the number of apples in the 12 bags.

The mean of "n" observations is given as

Mean = Sum of observations/the number of observations

8 = sum of observations/12

The total number of apples = 8 x 12 = 96

Hence, there are 96 apples in 12 bags.

Step-by-step explanation:

y = 79.31(1.48)^6

y=833.84

Answer:

it is 4cm long

Step-by-step explanation:

You multiply 6 by 2 to get 12, then subtract 12 from 20 and get 8. Then you divide 8 by 2 to get 4. If you want to check it, you can add 6+6+4+4 to get 20

Answer: 4

Step-by-step explanation: the definition of a rectangle states that opposite sides of the rectangle are congruent. this means that there is 2 sides that measure 6cm. These two sides added together give us 12cm. By working backwards, we can subtract 12cm from the perimeter (20cm), this gives us 8cm. by diving that by 2 we can find the lenght of the missing sides, 4cm each.

Step-by-step explanation:

Given: 60% students were in high school, 40% were in middle school and of the high school students, 30% had visited a foreign country

To find: probability that the student is in high school and has visited a foreign country

Solution:

Let x denotes total number of students

Number of students in high school = 60% of x = [tex]\frac{60}{100}x[/tex]

Number of students in middle school = 40% of x = [tex]\frac{40}{100}x[/tex]

Number of students who are in high school and have visited foreign country =  30% of Number of students in high school = [tex]\frac{30}{100}(\frac{60}{100})x=\frac{18}{100}x[/tex]

Probability that the student is in high school and has visited a foreign country = Number of students who are in high school and have visited foreign country/ Total number of students = [tex]\frac{\frac{18}{100}x}{x}=\frac{18}{100}=0.18[/tex]

Answer:

Type 7.5 in the box!

Step-by-step explanation:

Consider the trapezoid formula ( ( base 1 + base 2 ) / 2 ) * height;

[tex]Length of Base 1 - 1 unit,\\\\Length of Base 2 - 4 units,\\\\Length of Height - 3 units ( length of x - intercept in shaded region )\\\\Area of Trapezoid = ( Average of Bases ) * Height = ( ( 1 + 4 ) / 2 ) * 3 = ( 5 / 2 ) * 3 = 7.5 square units,\\\\Solution; 7.5 square units[/tex]

Area = 7.5 square units

The area of the trapezoid is 7.5 square units.

The length of base 2 = 4 units.

The length of height = 3 units.

The area of the trapezoid

= (Average of the two bases) × Height

Putting all the values in the above formula, we get

The area of the trapezoid

= {(1 + 4)/2} × 3

= 7.5 square units.

Hence, the area of the trapezoid is 7.5 square units.

To learn how to find the area of the trapezoid, refer:

Answer:

[tex]g(x)=-5\cos (2x)[/tex]

Step-by-step explanation:

The given function is

[tex]f(x)=5\cos (2x)[/tex]

If a function reflected over the x-axis, then x-coordinate remains same but the sign of y-coordinate is changed.

[tex]P(x,y)\Rightarrow P'(x,-y)[/tex]

If function f(x) is a reflection over the x-axis to get the of g(x), then the resultant function is

[tex]g(x)=-f(x)[/tex]

Substituting the value of function f(x), we get

[tex]g(x)=-5\cos (2x)[/tex]

Therefore, the required function is [tex]g(x)=-5\cos (2x)[/tex].

Answer:

c= 3/5(n)+2.5

Step-by-step explanation:

Let

c -----> the cost of some taxi journeys

n ----> the number of miles

we know that

The graph is a line

The equation of a line in slope - intercept form is

c=m(n)+b

where

m is the slope

b is the c-intercept (value of c when the value of n is equal to zero)

Observing the graph  we have the points

(0,2.5), (5,5.5)

Find the slope

The formula to calculate the slope between two points is equal to

m= c2-c1/n2-n1

substitute the values

m=5.5-2.5/5-0

m=3/5

we have

b=2.5 -----> because the point (0,2.5) is the c-intercept

substitute in the equation of slope-intercept form

c=3/5(n)+2.5

Step-by-step explanation:

Assume that your box-and-whisker plots look like those below.

1. Compare medians

Group A = 79

Group B = 79.5

The median of Group A is less than that of B

Correct.

2. Compare ranges

Group A: 82 - 76 = 6

Group B: 81 - 76 = 5

The range of Group A is greater than that of Group B.

Option B is wrong.

3. Compare Q1s

Group A: 78

Step-by-step explanation:

Properties of a kite are:

a) They have two congruent sides

b) Their diagonal is perpendicular to each other.

c) On a kite, we also have two angles that are opposite and congruent to each other. These angles are the same

We would be using the property of a kite that says "On a kite, we also have two angles that are opposite and congruent to each other. These angles are the same" to solved this question.

In the diagram , the angles Z and X are opposite and congruent to one another. This means they are equal to each other.

Since angles Z= angle X

Let us call both of them angle a

Since a Kite is a Quadrilateral shape, the sum of angles in a Quadrilateral = 180°

Angle W = 90°

Angle Y = 130°

Angle X = a°

Angle Z = a°

Hence,

90° + 130° + a° + a° = 360°

220° + 2a° = 360°

2a° = 360° - 220°

2a° = 140°

a° = 140/2

a° = 70°

Therefore, from the calculation above, we can say that the measure of x = 70°

Answer:

Dear friend i hope the answer is 4753 which is the mystery four digit number.

Answer:

See below.

Step-by-step explanation:

Squaring a number means to multiply the number by itself.

For example, 3^2 means 3 * 3.

8^2 means 8 * 8.

(-6)^2 means (-6) * (-6).

In each case above, you see that the number that is squared is multiplied by itself.

In this case, (-4.5)^2, squaring the number -4.5, means multiply the number -4.5 by the number -4.5

(-4.5)^2 = (-4.5) * (-4.5)

Now we need to actually multiply -4.5 by -4.5

When you multiply a negative number by a negative number, the result is positive, so the product of -4.5 and -4.5 is a positive number. To find that number, you multiply 4.5 by 4.5

4.5 * 4.5 = 20.25

Therefore, (-4.5)^2 = 20.25

Answer:

x = - 1

Step-by-step explanation:

Given a parabola in standard form

y = ax² + bx + c ( a ≠ 0 ) , then the equation of the axis of symmetry is

x = - [tex]\frac{b}{2a}[/tex]

y = - 2x² - 4x - 11 ← is in standard form

with a = - 2 and b = - 4 , thus

x = - [tex]\frac{-4}{-4}[/tex] = - 1

x = - 1 is the equation of the axis of symmetry

Answer:

250 cards

Step-by-step explanation:

Let the number of baseball cards he originally had be x.

He sold 20% of the baseball cards after week one. This means that after week one the number of cards he had was:

x - (20/100 * x) = x - 0.2x = 0.8x

During week two he bought 20% more cards than he had after week one. This means that after week two, he had:

0.8x + (20/100 * 0.8x)

= 0.8x + (0.2 * 0.8x)

= 0.8x + 0.16x = 0.96x

He now has 10 fewer cards. This means that:

x - 10 = 0.96x

Collecting like terms:

x - 0.96x = 10

0.04x = 10

=> x = 10/0.04 = 250

He had 250 cards originally.
