Answer:

the answer is D:  the median of both the dot plot A and B is the same

Step-by-step explanation:

median is the middle value; after arranging the data in ascending or descending order...the mean of the two values is an even # of values

The median of dot plot A and median of dot plot B is 5; so therefore, the pots A and B are the same.

Answer:

the median of both thedot plots A and B is the same.

Step-by-step explanation:

The median is the middle value after arranging the data in an ascending or descending order, or the mean of the two middle values if there is an even number of values.

The median of dot plot A and the median of dot plot B is 5.

Therefore, the median of both thedot plots A and B is the same.

x^2-5x-36 =0

=》(×+4)(x-9) =0

=》 x = 9 or -4

positive solution for x is 9

For this case we must find the positive solution of the following quadratic equation:

[tex]x ^ 2-5x-36 = 0[/tex]

To find the solutions we factor, that is, we look for two numbers that when multiplied give as result -36 and when summed give as result -5.

These are:

-9 and +4

[tex]-9 * 4 = -36\\-9 + 4 = -5[/tex]

So, we have:

[tex](x-9) (x + 4) = 0[/tex]

The roots are:

[tex]x_ {1} = 9\\x_ {2} = - 4[/tex]

The positive solution is 9.

Answer:32 black

6 white long sleeve shirts

Step-by-step explanation:

62+6=68

100-68=32

Answer:

Step-by-step explanation:

Since out of 62 who preferred short- sleeved shirts, half were white and half were white.

So members who preferred black and white short sleeved T- shirts = [tex]\frac{62}{2}[/tex] = 31 each

Since members who liked white T-shirts = 37

So members who preferred long sleeved white T-shirts = 100 - (37+31) = 32

Therefore, the table formed will be

                         Short-sleeved          Long sleeved            Total

Black                         31                             32                        63

Answer: 1: 3mm

Answer:2: A rectangle with 4 congruent sides is a square.

A = s^2

s^2 = A

s^2 = 36 mm^2

s = sqrt(36 mm^2)

s = 6 mm

Step-by-step explanation:

Part A. The length of the rectangle is 3 m.

Part B. The length of the single side of the rectangle or square is 6 mm.

The area of a rectangle is defined as the total surface area obtained by multiplying its length and width.

Part A

Given that the area of a rectangle is 60 square meters and the width of the rectangle is 20 m. The length of the rectangle will be given below.

[tex]a = l\times w[/tex]

Where a is the area of the rectangle, l is the length and w is the width of the rectangle.

[tex]60 = l\times 20[/tex]

[tex]l = \dfrac {60}{20}[/tex]

[tex]l = 3\;\rm m[/tex]

Thus the length of the rectangle is 3 m.

Part B.

A rectangle has equal sides and area of 36 square mm. Thus the rectangle will be a sqaure. The area of the square is the product of 2 sides.

[tex]a = s^2[/tex]

Where a is the area of the square and s is the side of the square.

[tex]36 = s^2[/tex]

[tex]s = \sqrt{36}[/tex]

[tex]s = 6 \;\rm mm[/tex]

Hence the length of the single side of the rectangle or square is 6 mm.

Let x be the variable that belongs to the real numbers. Then, all reals less than 70 can be expressed as:

[tex]x <70[/tex]

The tip of the inequality is directed to the real numbers, since they tell us that they are less than 70, for 70 the inequality remains open.

Answer:

Answer:

Step-by-step explanation:

Triangles JKN MLN are similar.

There is a right angle at J and M. <JNK and <MNL are vertically opposite. By AA the triangles are similar.

Find JN

JK = 3

LM = 9

JK/LM = JN/(20 - JN)

3/9 = JN/(20 - JN)

1/3 = JN/(20 - JN)

20 - JN = 3JN

20 = 4JN

JN = 5

NM = 20 - 5

NM = 15

Find KN

KN^2 = JN^2 + JK^2

JK = 3

JN = 5

KN = ?

KN^2 = JK^2 + JN^2

KN^2 = 3^2 + 5^2

KN^2 = 34

KN = sqrt(34)

Find LN

LN = ?

MN = 15

Answer:

After 11 years the value of the investment reaches $1500.00

.

Step-by-step explanation:

The formula used for finding time (when the value reaches certain amount) is:

[tex]A= P(1+\frac{r}{n})^{nt}[/tex]

where A= Future VAlue

P= Principal Value

r= rate of interest (in decimal)

n= no of times investment is compounded

t= time

Putting the values given and finding Time t,

A= $1500

P= $1200

r= 2% or 0.02

n= 4 (compound quarterly)

[tex]A= P(1+\frac{r}{n})^{nt}[/tex]

[tex]1500= 1200(1+\frac{0.02}{4})^{4t}[/tex]

Dividing both sides by 1200 and solving 0.02/4 = 0.005

[tex]1.25= (1+0.005)^{4t}[/tex]

[tex]1.25= (1.005)^{4t}[/tex]

Since t is in power we take the logarithm ln on both sides.

The rule of logarithm says that the exponent can be multiplied with the base when taking log

[tex]\ln1.25=ln( 1.005)^{4t}\\\ln1.25=4t * ln( 1.005)\\0.22 = 4t * 0.005\\Solving\,\,\\\frac{0.22}{4*0.005} = t\\=> t= 11\, years[/tex]

Graph 2 is the graph that represents the linear function y = –3x + 1

Points on graph 2 are (0,1) (-1,4) (1,-2)

Substitute the points in the linear function

(0,1)

y = –3x + 1

y = -3*0 +1

y = 1

(0,1) is correct point

(1,-2)

y = –3x + 1

EXPLANATION

The formula for calculating the volume of a rectangular prism is

[tex]Volume =lbh[/tex]

The given rectangular prism has

length,

[tex]l = 8 \: in[/tex]

The width is

[tex]w = 4 \frac{1}{2} in[/tex]

and the height is

[tex]h = 3\frac{1}{2} in[/tex]

We substitute the values into the formula to obtain;

[tex]Volume =8 \times 4 \frac{1}{2} \times 3 \frac{1}{2} [/tex]

[tex]Volume =8 \times 4.5 \times 3.5[/tex]

[tex]Volume =126 {in}^{3} [/tex]

Answer:

The correct answer is option D.  126 in³

Step-by-step explanation:

Formula:-

Volume of cuboid - lbh

l - Length of cuboid

b - Breadth of cuboid

h - Height of cuboid

To find the volume of prism

Here rectangular prism is like a cuboid.

l = 8 in, b = 4 1/2 = 9/2 and h = 3 1/2 = 7/2

Volume = lbh

     = 8 * 9/2 * 7/2 = 126 in³

Therefore the correct answer is option D.  126 in³

Step-by-step explanation:

EMI formula is :

[tex]\frac{p*r*(1+r)^{n} }{(1+r)^{n}-1 }[/tex]

Calculation for convertible car:

p = $28700

r = 6/12/100=0.005

n = [tex]6\times12=72[/tex] months

Putting the values in formula we get

[tex]\frac{28700*0.005(1.005)^{72} }{(1.005)^{72}-1 }[/tex]

= $475.67

Calculation for sports car:

p = 29200

r = 6/12/100=0.005

n = [tex]6\times12=72[/tex] months

Putting the values in formula we get

[tex]\frac{29200*0.005(1.005)^{72} }{(1.005)^{72}-1 }[/tex]

= $483.96

We can see that in both cases the EMI is below $490.

As Chuck can afford a $490-per-month car payment. So, he can afford both cars. (one car out of both)

Therefore, option D is correct. Chuck can afford both the convertible and the sports car​.

Answer:

C) (25, -16), r = 10

Step-by-step explanation:

The equation of a circle: (x - w)² + (y - h)² = r², where (w, h) is the coordinate of the center, and r is the radius of the circle.

w = 25, h = -16, r = √100 = 10

So, the coordinate is (25, -16), and the radius is 10 units.

Answer:

C

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

(x - 25)² + (y + 16)² = 100 ← is in standard form

with (h, k) = (25, - 16) ← centre and r = [tex]\sqrt{100}[/tex] = 10

Answer:

AB = 16

Step-by-step explanation:

The perimeter is the sum of all 5 sides of the pentagon

Sum the 5 sides, equate to 69 and solve for x

12 + 3x + 10 + x + 3 + 2x + 2 = 69

6x + 27 = 69 ( subtract 27 from both sides )

6x = 42 ( divide both sides by 6 )

x = 7

AB = 2x + 2 = (2 × 7) + 2 = 14 + 2 = 16

There are a total of [tex]\(9\)[/tex] integers that satisfy the given inequality.

To solve the inequality [tex]\(3n^2 - 4 \leq 44\)[/tex], follow these steps:

1. Add 4 to both sides of the inequality:

  [tex]\[ 3n^2 \leq 48 \][/tex]

2. Divide both sides by 3:

  [tex]\[ n^2 \leq 16 \][/tex]

3. Take the square root of both sides. Remember to consider both the positive and negative square roots since [tex]\(n^2\)[/tex] can be positive or negative:

  [tex]\[ |n| \leq 4 \][/tex]

This inequality implies that [tex]\(n\)[/tex] must be within the interval [tex]\([-4, 4]\)[/tex] inclusive.

Now, count the integers within this interval: [tex]\(-4, -3, -2, -1, 0, 1, 2, 3, 4\)[/tex]. There are a total of [tex]\(9\)[/tex] integers that satisfy the given inequality.

The probable question may be:

"How many integers [tex]$n$[/tex] satisfy the inequality [tex]$3n^2 - 4 \le 44$[/tex]?"
