1/5 - {3/6 ÷ 9/18 × 1/2 - (1/3 + 2/5) by using bodmas rule

Answer:

w = 5.2

Step-by-step explanation:

4(2.25w + 3.1) - 2.75w = 44.9

9w + 12.4 - 2.75w = 44.9

6.25w + 12.4 = 44.9

6.25w = 32.5

w = 5.2

4(2.25w+3.1)-2.75w=44.9

9w+12.4-2.75w=44.9

9w-2.75w+12.4=44.9

44.9-12.4=32.5

9w-2.75w=32.5

6.3w/6.3=32.5/6.3

=5 10/63

Answer:

180 seconds or 3 minutes

Step-by-step explanation:

you need to find the least common multiple

2.45 N

weight = mass x 9.8 m/s^2

Answer:

Here,

Mass ( m ) = 250g = (250/1000) kg =0.25 kg

g =9.8 m/s^2

Weight ( W ) = ?

We know that,

Weight ( W ) = m*g [Where g is acceleration due to gravity]

                   = (0.25*9.8) N

                    = 2.45 N

Answer:

10 + 7z

Step-by-step explanation:

the product of z and 7 is

7z

adding 10 to the expression would be

10 + 7z

The required expression is the binomial 7z+10

Polynomial is made up of two terms, namely Poly (meaning “many”) and Nominal (meaning “terms.”). A polynomial is an expression composed of variables, constants, and exponents, combined using mathematical operations such as addition, subtraction, multiplication, and division (No division operation by a variable). Based on the number of terms present in the expression, it is classified as monomial, binomial, and trinomial. For example P(x) = x2-5x+11

Given here: The statement " Product of z and 7 added to 10"

Now the product of z and 7 is given by 7z

Now adding 10 to the monomial we get

7z+10

Thus the result is a binomial

Hence, The required expression is the binomial 7z+10

Answer:

the average distance between each data point and the mean. It gives us an idea about the variability in a dataset.

Here's how to calculate the mean absolute deviation.

Step 1.Calculate the mean.

Step 2: Calculate how far away each data point is from the mean using positive distances. These are called absolute deviations.

Step 3: Add those deviations together.

Step 4: Divide the sum by the number of data points.

Following these steps in the example below is probably the best way to learn about mean absolute deviation, but here is a more formal way to write the steps in a formula:

\text{MAD}=\dfrac{\sum{\lvert x_i-\bar{x} \rvert}}{n}MAD= ∑∣ xi -x /n

start text, M, A, D, end text, equals, start fraction, sum, open vertical bar, x, start subscript, i, end subscript, minus, x, with, \bar, on top, close vertical bar, divided by, n, end fraction

Example

Erica enjoys posting pictures of her cat online. Here's how many "likes" the past 666 pictures each received:

10, 15, 15, 17, 18, 21

Find the mean absolute deviation.

Step 1: Calculate the mean

The sum of the data is 96 total "likes" and there are 6 pictures.

\text{mean}=\dfrac{96}{6}=16

mean= 96/6=16

start text, m, e, a, n, end text, equals, start fraction, 96, divided by, 6, end fraction, equals, 16

The mean is 16

Step 2: Calculate the distance between each data point and the mean.

Data point Distance from mean

10 |10-16|=6

15 |15-16|=1

15 |15-16|=1

17 |17-16|=1

18 |18-16|=2

21 |21-16|=5

Step 3: Add the distances together.

6+1+1+1+2+5=16

Step 4: Divide the sum by the number of data points.

\text{MAD}=\dfrac{16}{6}\approx2.67MAD=

MAD=16/6 =2.67 Likes

On average, each picture was about 333 likes away from the mean.

that's the answer

Step-by-step explanation:

[tex]slope = \frac{y2 - y1}{x2 - x1} \\ = \frac{3 - - 5}{ - 9 - - 3} = \frac{8}{ - 6} \\ \frac{y - 3}{x - - 9} = \frac{8}{ - 6} \\ - 6(y - 3) = 8(x - - 9) \\ - 6y + 18 = 8x + 72 \\ - 6y = 8x + 72 -18 \\ - 6y = 8x + 54 \\ \frac{ - 6y}{ - 6} = \frac{8x}{ - 6} + \frac{54}{ - 6} \\ y = \frac{8x}{ - 6} - 9 [/tex]

Work Shown:

A = probability of landing on an odd number

A = 5/9 because there are 5 odd numbers out of 9 total

B = probability of getting heads

B = 1/2

C = landing on 3 on the spinner

C = 1/9

Multiply the values of A,B,C

A*B*C = (5/9)*(1/2)*(1/9) = (5*1*1)/(9*2*9) = 5/162

Note: The fraction 5/162 converts to the approximate decimal 0.03086 which then converts to 3.086%, when rounding to the nearest tenth of a percent we get 3.1%

Answer:

The distance to the top of the balloon is approximately 33.977 meters

Step-by-step explanation:

The (horizontal) distance from the hot air balloon from the observer, l = 30 m

The angle of elevation to the top of the balloon, θ = 28°

With the balloon standing upright, the distance to the top of the balloon, d, the height of the balloon, h and the horizontal distance to the balloon, l, form a right triangle, where;

d = The hypotenuse side

l = The leg adjacent to the reference (given) angle,

h = The leg opposite to the given angle, θ

By trigonometric ratios, we have;

[tex]cos\angle X = \dfrac{Adjacent\ leg \ length}{Hypotenuse \ length}[/tex]

From which we get;

[tex]cos\angle \theta = \dfrac{l}{d}[/tex]

[tex]cos(28^{\circ}) = \dfrac{30 \ m}{d}[/tex]

[tex]d = \dfrac{30 \ m}{cos(28^{\circ}) } \approx 33.977 \, m[/tex]

The distance to the top of the balloon, d ≈ 33.977 m
