What is the mean of the data set below?
15, 5, 16, 9, 14, 3, 4, 18, 10, 4

The true statement about the rectangle  is A. If w is 12 inches, then l is 10 inches

The given parameters are:

The perimeter of a rectangle is:

P = 2(L + W)

So, we have:

2(L + W) = 44

Divide by 2

L + W = 22

The area is calculated as:

A = LW

This gives

LW = 120

Express 120 as 12 * 10 and 10 * 12

LW =12 * 10 or LW = 10 * 12

By comparison, we have:

L = 12 and W = 10 or L = 10 and W = 12

When these values are substituted in L + W = 22, we have:

10 + 12 = 22 and 12 + 10 =22

This means that the dimensions of the rectangle are 10 by 12 inches or 12 by 10 inches

Hence, the true statement is A. If w is 12 inches, then l is 10 inches

Step-by-step explanation:

$72.45 can be rounded down to $72.00

$28.98 can be rounded up to $29.00

$72-$29= $43

let's say the number is "a", so

[tex]\stackrel{doubled}{2a}~~ \stackrel{decreased}{-} ~~\stackrel{by~this~much}{13.7} ~~ \stackrel{greater~than}{ > } ~~ 125.28 \\\\\\ 2a > 125.28-13.7\implies 2a > 111.58\implies a > \cfrac{111.58}{2}\implies a ~~ > ~~ 55.79[/tex]

Answer:

56

Step-by-step explanation:

The mean of the binomial distribution is (d) μ = 28,8

The given parameters of the binomial distribution are given as:

n = 48 and p = 3/5

The mean is then calculated using:

μ = np

This gives

μ = 48 * 3/5

Evaluate

μ = 28,8

Hence, the mean of the binomial distribution is (d) μ = 28,8

Answer: 10x2π:36x2

Explanation: So the area of the circle is πr2=10x2π. So the ratio of the area of the circle to the area of the square is 10x2π:36x2, which is equivalent to 5π:18, as required.

Answer:

PEMDAS.

1. PARENTHESIS

2. EXPONENTS

3. MULTIPICATION

4. DIVISION

5. ADDITION

6. SUBTRACTION

Follow the steps of BEDMAS:

B = Brackets

E = Exponents

D = Division

M = Multiplication

A = Addition

S = Subtraction

Let's try 1) with these steps.

5 - 6 + 2(3)

We can see there are brackets. When a number is placed near a bracket, it means we need to multiply.

2 x 3 = 6

Let's check our expression.

5 - 6 + 6

We can see that there is addition and subtraction. When we have addition and subtraction together we can solve left to right. The same applies to multiplication and division.

So let's solve the rest of it.

5 - 6 = -1

-1 + 6 = 5

5 is the answer to 1).

Now I hope you can solve the rest accordingly with my help. If you are in a time constraint or genuinely don't feel like doing math, understandable. In that case, simply use any online scientific calculator :)

Answer: 2.5

Step-by-step explanation:

-2x + 14 + 10x = 34

8x + 14 = 34

8x = 34 - 14

8x = 20

x = 20/8

x = 5/2

x = 2.5

266.605 is the answer.

Step-by-step explanation:

70.6 + 74.02 + 121.985 = 266.605

The number tablets per dose of drug A to be administered on the patient is 4 tablets

1 gram = 1000 milligram

Number of tablets to administer = Drug A provided / Dose

= 1 gram / 250 milligram

= 1000 milligram / 250 milligram

Number of tablets to administer = 4 tablets

Therefore, the number tablets per dose of drug A to be administered on the patient is 4 tablets

Answer:

Standard form: 2x²-5x+12=0

a=2 b=-5 c=12

Step-by-step explanation:

2(x+3)²-5x=6

2(x²+9)-5x-6=0

2x²+18-5x-6=0

2x²-5x+18-6=0

2x²-5x+12=0

a=2 b=-5 c=12

Answer:

Using PEMDAS we can see that P or parenthesis is first so we would subtract 5 from 5 in the beginning.  That would result in a 0 which would then get multiplied with 12 to still have 0.

[tex]12(5-5) + 3 * 5[/tex]

[tex]12(0) + 3 * 5[/tex]

[tex]0 + 3 *5[/tex]

Now that we completed that part, the only thing that we have left to do is to multiply the last two numbers, 3 and 5.

[tex]3*5[/tex]

[tex]15[/tex]

Therefore, our final solution is 15.

The y-coordinate of the point that divides the directed line segment from J to K into a ratio of 5:1 is 0.

From the attached line segment graph, we see the coordinates as;

J (1, -10) and K (7, 2)

Let us assume that, point L divides the directed line segment from J to K into a ratio of 5:1.

From the properties of coordinate geometry we know that, the coordinates of point that divides the line joining (x₁, y₁), (x₂, y₂) in m:n, are;

[(mx₂ + nx₁)/(m + n)], [(my₂ + ny₁)/(m + n)]

Plugging in the relevant values gives;

[(5 * 7 + 1 * 1)/(5 + 1)], [(5 * 2 + 1 * -10)/(5 + 1)]

⇒ (6, 0)

Therefore, the y-coordinate of the point that divides the directed line segment from J to K into a ratio of 5:1 is 0.

Answer:

B. <1 = 35, m<2 = 30

Step-by-step explanation:

To figure out m<1 I first need to figure out the other missing angle. A straight line is a 180 degree angle. Taking that information you can do 180 - 115. This means that the missing angle is 65 degrees. The interior angles of triangles always add up to 180.

80 + 65 = 145

180 - 145 = 35

<1 = 35

Repeat with the other side.

85 + 65 = 150

180 - 150 = 30

<2 = 30

Based on the amount borrowed and the interest per year, Big Brothers, Inc will pay an annual payment of $59,973.15.

This can be found by using the present value of an annuity formula because the annual payment will be constant and therefore like an annuity.

Formula is:

Present value of annuity = Annual payment x ( 1 - (1 + rate) ^ -number of periods) / rate

Solving gives:

267,999 = Amount x ( 1 - ( 1 + 18.16%)⁻¹⁰) / 18.16%

267,999 = Amount x 4.46865

Amount = 267,999 / 4.46865

= $59,973.15
