if you were to flip the coin 15, how many times will the coin land on tails based on experimental probability? jordan flipped a count of 45 times.His result are below: heads: 24 tails: 21

Answer:

5) [tex]x=\sqrt{317}[/tex]

6) [tex]x = \sqrt{186}[/tex]

Step-by-step explanation:

You have to know Pythogeroem theorem, which is:

[tex]a^2 +b^2 = c^2[/tex],   where a, b are the sides of the triangle and c is the hypothesis (the side in front of the 90° angle)

5)

Plug in the numbers into the equation, make sure c is the hypothesis (the side in front of the 90° angle). Hypothesis is x in this example.

[tex]14^2+11^2 = x^2\\196 + 121 = x^2\\\sqrt{196 + 121} = x\\\sqrt{317} = x[/tex]

6) Hypothesis is [tex]\sqrt{226}[/tex]

 [tex]7^2 + x^2 = \sqrt{226}^2\\7^2 + x^2 = 226\\49 + x^2 = 226\\x^2 = 186\\x= \sqrt{186}\\[/tex]

Same steps for 7) and 8)

Step-by-step explanation:

[tex]c = 2\pi \: r \\ 26.69 = 2\pi \: r \\ r = 26.69 \div 2(3.14) \\ r = 4.25 \: cm[/tex]

Answer:

4.25 cm

Step-by-step explanation:

Circumference of a circle = 2πr  (where r is the radius)

[tex]\implies 26.69=2 \pi r[/tex]

[tex]\implies r=\dfrac{26.69}{2\pi }[/tex]

[tex]\implies r=4.247845431...[/tex]

[tex]\implies r=4.25\:\textsf{cm (nearest hundredth})[/tex]

Using [tex]\pi=3.14[/tex]:

[tex]\implies r=\dfrac{26.69}{2 \cdot 3.14}=4.25\: \sf cm[/tex]

x>2 and x<4

since both are dashed that means they are both not including the x-values, so they are no equal signs with the greater or less than signs.

the shaded area is more than 2 but less than 4, not including 2 and 4 because they are dashed lines.

The interest rate Mr Frank must invest his money is at 10% per year compounded monthly

That is option 1.

The amount for Mr Frank's son school fees = R60 000.00

Cash at hand( principal amount) = R46 150.30

Therefore the simple interest needed to make up R60 000.00= R60 000.00 - R46 150.30= 14,849.70

Time of investment = 3 years

Therefore the rate = simple interest × 100/ principal×time

Rate (R) = 14,849.70 × 100/ 46 150.30× 3

= 1,484,970/135,450.9

= 10.0%

Therefore, the interest rate Mr Frank must invest his money is at 10% per year compounded monthly.

Answer:

The Answer is 108, simply you find the volume of the cube 6 x 6 x 6 = 216. Since there are 108  "1-inch" cubes that fill the big cube half way you divide the volume of the big cube 216 by 2, so 216/2 which 108 will be your answer because, if you have a big cubed box that measures 6 inches in width, height, and length and you have 216 "1-inch" cubes, then you fill the box halfway, you will be left over with 108 "1-inch" cubes. You can also think about this with a cup of water, if you pour 3 cups of water into a glass and you drink half of that glass you will have half a cup of water or 1.5 cups of water left, if you drink 1/3 of the glass you will have 2 cups left.

Can't help you there m an.

¯\_(ツ)_/¯

Then you say 5 is farther from 0 than 9.

Its actually closer to 0 than 9 is from 0. Like literally count backward and you can see you have to count less from 5 to 0 than you would for 9 to 0.

Answer:

this question have the 552.792 and centimeters of square

Answer:

28 cm

Step-by-step explanation:

Area = 46.75 =  l * (l-3)     shows l = 8.5 cm  (using Quadratic Formula)

    then w = 5.5  

perimeter = 2 * ( 8.5+5.5) = 28 cm

The perimeter of the given card is 28 cm.

Perimeter of an object is given by adding the side lengths of the object.

Given that, the width w of a credit card is 3 cm shorter than the length. The area is 46.75 cm².

We need to find the perimeter of the credit card,

Let the length be l,

Therefore,

Area = length x width

46.75 = l x (l-3)

46.75 = l² - 3l

l² - 3l - 46.75 = 0

Finding l, we get,

l = 8.5, l = -5.5

Since, length cannot be negative so, l = 8.5 cm

So, width = 8.5 - 3 = 5.5 cm

Perimeter = 2(l+w)

= 2(5.5+8.5) = 28 cm

Hence, the perimeter of the given card is 28 cm.

Answer:

Answer to part A:

1 notebook = $2.5

1 pen = $1.5

Answer to part B:

           = 3 pens.

Step-by-step explanation:

4n + 3p = $14.50

5n + 6p = $21.50

5(4n + 3p) = $14.50

4(5n + 6p) =$ 21.50

20n + 15p = $72.50

20n + 24p = $86

20n - 20n        = 0

15p - 24p         = -9p

$72.50 - $86   = -$13.5

-$13.5 ÷ -9 = $1.5p

4n + 3p = $14.50

4n + 3($1.5) = $14.50

4n + $4.5 = $14.50

4n = $14.50 -  $4.5

4n = $10.00

n = $2.5

1 notebook = $2.5

1 pen = $1.5

1 ($1.5) = 3($2.5)

$1.5 + $7.5 = $9.0

$27 ÷ 9 = $3

3 ( $1.5 + $7.5 ) = 3 ( $9.0 )

( $4.5 + $22.5 ) = ( $27 )

  $4.5 + $22.5 = $27

           = 3 pens.

Using it's concept, it is found that there is a 85% probability that the moviegoer is not in the 65-74 age range.

A probability is given by the number of desired outcomes divided by the number of total outcomes.

In this problem, the total number of moviegoers is given by:

T = 1224 + 1220 + 940 + 830 + 730 = 4944.

Out of those, the number not in the 65-74 age range is:

D = 4944 - 730 = 4214.

Hence, the probability is given by:

p = 4214/4944 = 0.85 = 85%.

There is a 85% probability that the moviegoer is not in the 65-74 age range.

By comparism using the given scale ratio, the weight of Ellie at birth is 7.7pounds.

Ratio simply compares values, it shows how much of one thing is related or compared to another thing.

Given the data in the question;

To determine the weight of Ellie, we simply say;

0.75pounds : 0.9pounds = 6.4pounds : X

0.75pounds / 0.9pounds = 6.4pounds / X

Cross multiply

0.75pounds × X = 0.9pounds × 6.4pounds

0.75pounds × X = 5.76pounds²

X = 5.76pounds² / 0.75pounds

X = 7.68pounds

X = 7.7pounds

Answer:

22.4

Step-by-step explanation:

Let that number be " x ".

The difference between 32.6 and a number is 10.2

32.6 - x = 10.2

Add x on both sides,

32.6 - x + x = 10.2 + x

32.6 = 10.2 + x

10.2 + x = 32.6

Substract x on both sides,

10.2 - 10.2 + x = 32.6 - 10.2

x = 22.4

Therefore,

The number is 22.4

Answer:

22.4

Step-by-step explanation:

First we can make an equation to find the unknown number:

Difference mean subtraction:

32.6 - x = 10.2

To do this we can subtract 32.6 from both sides to isolate -x or to make -x the subject:

32.6-x-32.6 = 10.2 - 32.6

-x = -22.4

Now we can multiply both sides by -1 to make x positive:

-(-x) = -(-22.4)

x= 22.4
