You didn't give the numbers but an expression is a problem with no equals so you do t pit the total if that helps at all

Express each of the following fractions as a percentage 9 by 27

valentina_108 [34]

Answer:

9/27 = 33.3% (rounded to the nearest tenth)

Step-by-step explanation:

Let, x equal the percent out of 100

Step 1: Cross multiply

1. 9/27 ∙ x/100

2. 900 = 27x

Step 2: Divide both sides by 27

1. 900/27 = 27x/27

2. 33.333333%... = x

3. Hence, the answer is 33.3% (rounded to the nearest tenth)

0.2 is 10 times as much of... well you must do the opposite of what it says... well, times means to multiply and the opposite of multiplying is dividing, 0.2 divided by 10 is 0.02

So... 0.2 is 10 times as much as 0.02

Now, 0.2 is 1/10 of... well this question shows to divide and we must do the opposite, which is... multiplying 0.2 times 10 is 2

So... 0.2 is 1/10 of 2

point f is inside regular pentagon abcde so that triangle abf is equilateral. Find all the angles of abcf, in degrees

Citrus2011 [14]

The equilateral triangle, and regular pentagon, gives the measure of the

angles formed from which the interior angles of ABCF can be found.

Response:

∠BCF = 66°

∠BAF = 60°

∠CFA = 126°

∠ABC = 108°

<h3>Which properties of figures can be used to find the interior angles?</h3>

The given parameters are;

The point in the regular pentagon is point <em>F</em>

ΔABF is an equilateral triangle

Required:

The angles in quadrilateral ABCF

Solution:

Given that ΔABF is an equilateral triangle, we have;

∠FBA = ∠BAF = ∠AFB = 60°

∠ABC = An interior angle of a regular pentagon = 108°

Which gives;

∠FBC = 108° - 60° = 48°

∠BCF = ∠BFC = Base angles of an isosceles triangle ΔBCF

Which gives;

∠BCF + ∠BFC + 60° + 60° + 108° = 360°, angle sum property of a quadrilateral

2·∠BCF + 60° + 60° + 108° = 360°

2·∠BCF = 360° - (60° + 60° + 108° ) = 132°

∠BCF = 132° ÷ 2 = 66°

The interior angles of quadrilateral ABCF are;

∠BCF =<u> 66°</u>

∠BAF =<u> 60°</u>

∠CFA = 66° + 60° = <u>126°</u>

∠ABC =<u> 108°</u>

Suppose you have a bag of 10 coins. Nine of them are fair coins, that is, if you toss any of these 9 coins the probability of ge

garik1379 [7]

Answer:

Step-by-step explanation:

Given:

we have 10 coins

nine of them are fair coins, which means: $P(H)=\frac{1}{2}; P(T)=\frac{1}{2}$

but one coin is biased it has head on both sides which means $P(H)=\frac{1}{1}; P(T)=\frac{0}{1}=0$

expected number of heads for tossing 9 coins = $9(\frac{1}{2})=\frac{9}{2}=4.5$

The coin 10 is biased with only head on both sides

The expected number of heads tossing this coin is = 1

Therefore, the expected number of heads if all 10 coins are tossed together is = $4.5+1=5.5$

Using indicator random variables:

The number of unbiased coins = 9: n=9

$P(H)=\frac{1}{2}=0.5\\\\F(x)=nP=9\times 0.5=9.5$

One coin is biased with only head. Therefore:

$F(x)=1$

Finally, $F(x)=4.5+1=5.5$

The expected number of heads = 5.5
