help me solve this please

Answer:

I'm sorry me dont know kfnkdks

Answer:

A

Step-by-step explanation:

Area of the rectangle

A = base x width = 8 x 6 = 48 cm^2

Area of the triangle

A = (base x height)/2 = (6 x 4)/2 = 12 cm^2

two semicircles are equal to a circle

radius = diameter / 2 = 3/2 = 1.5 cm

A = radius^2 x pi = 1.5^2 x pi = 7 cm^2  (round to the nearest whole number)

total area

48 + 12 + 7 = 67 cm^2

Answer:

679.20

Answer:

50

Step-by-step explanation:

all triangles equal a total of 180 degrees

so add 40+90

130 subtract

180-130 = 50

Answer:

the z-score is within 3

Step-by-step explanation:

first you got to take the standard deviation and add it to the mean since 375 is greater than 250. so the equastion would be

250+50=300+50=350+50=40

so the z-score for the value of 375 is within 3      

Answer: 2

Step-by-step explanation:

z=\frac{x-\mu}{\sigma}

z=

σ

x−μ

​

z-score formula

z=\frac{300-250}{25}

z=

25

300−250

​

Plug in values

z=\frac{50}{25}

z=

25

50

​

Subtract

z=2

z=2

Divide

\text{They scored 2 standard deviations above the mean.}

They scored 2 standard deviations above the mean.

Answer:

The IQR (interquartile range) of the data set represented by this box plot is 22 units.

Step-by-step explanation:

Each number of the data set represented as a box plot is something the numbers have individually. The lowest number there (the first number), 38, is called the minimum. The highest number there (the last number), 75, is called the maximum. The second number there, 45, is called the lower quartile. The third number there, 50, is called the median or middle quartile. The fourth number there, 67, is called the higher quartile. In order to find the interquartile range, you need to find the difference between the lower quartile and higher quartile, which means to subtract.

67 (highest quartile) - 45 (lower quartile) = 22 (interquartile range)

Therefore, the IQR (interquartile range) of the data set represented by this box plot is 22 units.

Answer:

It’s 22

Answer:

4. (-2 1/2, 4 1/2)

Step-by-step explanation:

Midpoint Formula is (x1+x2)/2, (y1+y2)/2

So (-6+1)/2 , (1+8)/2 = (5)/2, (9)/2 = (2.5,4.5)

And that in fraction form is (-2 1/2, 4 1/2)

Answer:

All elements of the dataset will be whole numbers

Step-by-step explanation:

Given

[tex]Rule \to Add\ 5[/tex]

[tex]Start = n[/tex] ---- whole number

Required

A true statement about the list

If the starting point is n, then the list elements are as follows:

[tex]n , n + 5, n + 10, n + 15,....[/tex]

Also, since n is a whole number and 5 (the rule) which is added to the dataset is also a whole number;

Then the other elements of the dataset will be whole numbers

Answer:

Find the percentage of the original or real number.

Multiply the final number by 100.

Divide the result of the multiplication by the percentage.

Have a great day

The proportion of the original or true number is then added 100 to the final figure.

It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.

Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.

Let's suppose it is required to find the x percentage of y:

First step:

= x% of y

Second step:

= (x/100)y

Third step: Divide x by 100

= 0.01xy

Fourth step: Multiply the remaining term(0.01x and y).

= 0.01xy

The fifth step: Round off if required

= 0.01xy %

Calculate the proportion of the original or true number.

Add 100 to the final figure.

Subtract the percentage from the multiplication result.

Thus, the proportion of the original or true number is then added 100 to the final figure.

The answer is 5.66

Step-by-step explanation:

let the missing side be x

9² = 7² + x²

9² - 7² = x²

x² = 9² - 7²

x² = 81 - 49

x² = 32

x = √32

it's a right triangle, you should know how to find the area for this one :/   I'll give you the formula ,  you can push the buttons on a calculator ?  right? Okay to be fair, I see that there is one extra step, so i'll do that part for you.  

Ф=arcSin(8.5/15.7)

Ф = 32.77908067°

15.7*Cos(32.77908067°) = base

13.2 =base

⇒ use this formula ⇒ (1/2)*base*height*depth

just in case  base = 13.2

height = 8.5

depth = 6.2

you got it ?  right?

10)

we have to solve for the "adjacent side"  of the triangle, which will also be the diameter of the cylinder  , so

sin(Ф) = 9.5/19.3

Ф= arcSin(9.5/19.3)

Ф= 29.48712567°

19.3*cos(29.48712567°) = Adjacent

16.8 =Adjacent ( diameter of circle)

16.8/2 = radius

8.4 = radius

area of circle = [tex]\pi[/tex][tex]r^{2}[/tex]

area of circle = 221.6707776 [tex]m^{2}[/tex]

volume of a cylinder = area of circle * height

volume of a cylinder = 221.6707776 * 9.5

volume of a cylinder = 2105.872388 [tex]m^{3}[/tex]

11)

we need the formula for an equilateral triangle area

Equilateral Triangle Area = [tex]\sqrt{3}[/tex]/4)* [tex]a^{2}[/tex]

ETA = ([tex]\sqrt{3}[/tex]/4)*[tex]12^{2}[/tex]

ETA = 62.35382907 [tex]mm^{2}[/tex]

Volume Of Prism = length * area

VOP = 17 * 62.35382907

VOP = 1060.015094 [tex]mm^{3}[/tex]

multiply the volume value by 1000
