Use the distributive property to simplify the expressions: 3(x + 7)

Answer:

0.172 ; 0.0884 ; 0.9115

Step-by-step explanation:

Proportion or those who feel secure, p = 0.45

Sample size, n = 8

Using the binomial distribution formula :

P(x =x) = nCx * p^x * (1 - p)^(n - x)

A.) p(x = 5)

P(x =5) = 8C5 * 0.45^5 * 0.55^3

P(x = 5) = 56 * 0.0184528125 * 0.166375

P(x = 5) = 0.1719248540625

P(x = 5) = 0.172

B.) P(x > 5)

P(x > 5) = P(x = 6) + P(x = 7) + P(x = 8)

P(x > 5) = 0.0703 + 0.0164 + 0.0017

P(x > 5) = 0.0884

C.) P( ≤ 5) = P(x = 0) + P(x = 1) + P(x = 2) + P(x = 3) + P(x = 4) + P(x = 5)

Using the binomial probability calculator to obtain a direct solution :

P( ≤ 5) = 0.9115

Step-by-step explanation:

Answer:

12√2, 12√2

Step-by-step explanation:

For x:

We have the hypotenuse and are trying to find the angle opposite to 45 degrees. Using sine = opposite / hypotenuse we get sin45=x/24 so x = 24sin45 = 24 * √2/2 = 12√2

Beacuse the angle is 45 degrees we know that the the missing angle is also 45 degrees (180 - 90 - 45 = 45) so x and y must be the same (the triangle is isosceles) so y is also 12√2

36.84%

Step-by-step explanation:

7/19% of a quantity expressed as a fraction of the quantity is [tex]\frac{7}{1900}[/tex].

Percentage is the fraction of a quantity expressed as a number out of hundred. For example 1% can be expressed as 1/100

A fraction is a number that consists of a numerator and a denominator. An example of a frication is [tex]\frac{7}{19}[/tex]. 7 is the numerator and 19 is the denominator.

In order to convert a percentage to a fraction, divide the fraction by 100

[tex]\frac{7}{19}[/tex] ÷ 100

= [tex]\frac{7}{19}[/tex] x [tex]\frac{1}{100}[/tex] = [tex]\frac{7}{1900}[/tex]

Answer:

Solving the inequality [tex]3x -2 < 4[/tex] we get [tex]\mathbf{x<2}[/tex]

Option D is correct option.

Step-by-step explanation:

We need to solve the inequality [tex]3x -2 < 4[/tex] and find value of x

Solving the inequality for finding value of x, we will keep x on left side of inequality and all other terms on the right side.

[tex]3x -2 < 4[/tex]

Adding 2 on both sides

[tex]3x -2+2 < 4+2\\3x < 6[/tex]

Now, we will divide 3 on both sides

[tex]\frac{3x}{3}<\frac{6}{3}\\x<2[/tex]

So, we get x < 2

Solving the inequality [tex]3x -2 < 4[/tex] we get [tex]\mathbf{x<2}[/tex]

Option D is correct option.

Answer:

[tex]P(Brown) = 0.0556[/tex] or [tex]P(Brown) = \frac{1}{18}[/tex]

Step-by-step explanation:

Given

[tex]Total = 18[/tex]

[tex]Green = 2[/tex]

[tex]Black = 5[/tex]

[tex]Blue = 8[/tex]

[tex]Brown = 1[/tex]

[tex]Red = 1[/tex]

[tex]White = 1[/tex]

Required

Determine the probability of selecting a brown ball

This is calculated as thus:

[tex]P(Brown) = \frac{Brown}{Total}[/tex]

Substitute values for Brown and Total

[tex]P(Brown) = \frac{1}{18}[/tex]

The answer can be in fraction or solved further as;

[tex]P(Brown) = 0.0556[/tex]

Answer:

What??

Step-by-step explanation:

Answer:

3p-p

Step-by-step explanation:

I always think of the negative sign out ruling the positive sign so let's do that for the -p part.

3p-p is what it becomes

Your question says simplify but just in case you want the answer here it is:

-p is also the same as -1p

So therefore we have

3p-1p

And we subtract the coefficients and keep the variable

2p would be your answer but once again I don't know if you wanted that so just to be sure I put 3p-p as my "answer".

Perimeter = 8pi

Step-by-step explanation:

The Rim if the leaf like shape is actually the quarter fo a circle. and 8 is the radius. So to find the perimeter is diameter time pi so 16 x pi is 16pi. And because its only a quarter its 4pi. Also, because there is 2 ramps 4pi times 2 is 8pi. So the answer is 8 pi.

Answer:

x=2

Step-by-step explanation:

4^2x-4=4^0

2x-4=0

2x=4

x=4/2

x=2

If the starting equation is

4²ˣ - 4 = 1

first move the 4 on the left to the right side:

4²ˣ = 5

Take the base-4 logarithm of both sides:

log₄(4²ˣ ) = log₄(5)

Drop the exponent on the left, using the property [tex]\log_b(a^n)=n\log_b(a)[/tex]:

2x log₄(4) = log₄(5)

Now [tex]\log_b(b)=1[/tex] for any b, so

2x = log₄(5)

Solve for x by dividing both sides by 2:

x = 1/2 log₄(5)

You can also express this as

x = log₄(√5)

to make the solution slightly more compact.

You can also use the change-of-base identity to rewrite the solution as

x = log(5) / (2 log(4))

where the base of the logarithm is arbitrarily chosen. Then

x = log(5) / log(4²)

x = log(5) / log(16)

x = log₁₆(5)

Answer:

x = 437.3 ft

Step-by-step explanation:

Angle of elevation = angle of depression = 29°

Reference angle = 29°

Adjacent side = x

Hypotenuse = 500

Applying trigonometric ratio, we have:

Cos 29 = x/500

Multiply both sides by 500

500*cos 29 = x

437.309854 = x

x = 437.3 ft (nearest tenth)

Answer:

The percent error of the length of the soccer field is 1.4%

Step-by-step explanation:

Actual length of soccer field = 500 feet

Length shown in measuring instrument = 493 feet

We need to find the percent error of the length of the soccer field.

The formula used to find percent error of the length of the soccer field is: [tex]Percent\:error=\frac{approximate\;value-exact\:value}{exact\:value}\times 100\%[/tex]

The exact length = 500

Approximate length = 493

Putting values and finding percent error

[tex]Percent\:error=|\frac{approximate\;value-exact\:value}{exact\:value}|\times 100\%\\Percent\:error=|\frac{493-500}{500}|\times 100\%\\Percent\:error=|-0.014|\times 100\%\\Percent\:error=0.014\times 100\%\\Percent\:error=1.4\%[/tex]

So, the percent error of the length of the soccer field is 1.4%
