Answer:

0.0287

Step-by-step explanation:

Using the binomial probability relation :

p = 0.76

q = 1 - p = 1 - 0.76 = 0.24

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

P(x = 2) = 6C2 * 0.76^2 * 0.24^4

P(x = 2) = 15 * 0.76^2 * 0.24^4

P(x = 2) = 0.02874507264

P(x = 2) = 0.0287

Answer:

341 in sq

Step-by-step explanation:

When you are finding the area of trapezoids you have to do b1+b2/2 times height because there are two bases you have to include them both so adding 40 and 22 gives 62 and you have to divide that by 2 because the numbers will be too big and way off so 62/2 = 31 and you multiply that by the height to get 341 in sq.

The ratio of Lujain's earning to total earning is equal to $100.

Given the following data:

To determine the ratio of Lujain's earning to total earning:

In this exercise, you're required to calculate the total amount of money that Lujan would earn from the given ratio. Thus, we would solve as follows:

For a ratio of 10:

[tex]Amount=\frac{10}{24} \times 240\\\\Amount=\frac{2400}{24}[/tex]

Answer:

A

Step-by-step explanation:

Division is always the greatest with fractions because instead of dividing, you really multiply the number and switch the numerator and denomintor to prodouce the answer.

Answer:

1. The first expression is the greatest.

2.a) (see below)

b) $10

Step-by-step explanation:

For the first expression, the negative signs cancel and since 7[tex]\frac{5}{6}[/tex] is smaller than 9[tex]\frac{3}{4}[/tex], we will get a number less than 1, but greater than zero.

For the second expression, since 7[tex]\frac{5}{6}[/tex] is negative and 9[tex]\frac{3}{4}[/tex] is not, we will get a negative number.

For the third expression, since two negative numbers are being combined, we will end up with a negative number.

For the fourth expression, since 7[tex]\frac{5}{6}[/tex] is smaller than 9[tex]\frac{3}{4}[/tex], we will get a negative number.

So, there is only expression that will turn out to be greater than zero (not negative), and hence its value is the greatest: the first expression.

a)

A tape diagram consists of three parts: the amount in each group, the number of groups, and the total number.

Here, the amount in each group is x-2, which is the total Andre makes in a week, after he donates $2 (x represents how much he's paid before donating). The number of groups represents how many weeks he'll be working, which in this case is five, and the total number, which is 40, is how much money he'll make in all.

b)

Remember that x represents how much Andre is paid before donating:

40 = (x-2)+(x-2)+(x-2)+(x-2)+(x-2)

40 = 5x -10

50 = 5x

x = 10

Answer:

20 divided by 5=4

Answer:

[tex]2X10^{3}[/tex]

Step-by-step explanation:

Answer:

B.

Step-by-step explanation:

$2.25 is the cost of each video that is rented, so $2.25 times v (or 2.25v) represents the cost of 'v' videos.

$20 is the constant, as it costs $20 to join the club. Since this doesn't change, it is the constant.

So, we would have the equation:

f(v) = 2.25v + 20

f(v) is the total cost.

B is your answer because it is the only one with the correct equation.

Hope this helps!

Answer:

24379/1000

Step-by-step explanation:

Make the all the denominators the same and you have to multiply it by the same too.

Answer:

[tex]24\frac{379}{1000}[/tex]

Step-by-step explanation:

To solve this we need to know the order of operations (that division and multiplication has to be done before addition and subtraction).

And so we get that...

24 + 3/10 + 7/100 + 9/1000 = 24 + [tex]\frac{300}{1000}[/tex] + [tex]\frac{70}{1000}[/tex] + [tex]\frac{9}{1000}[/tex] = [tex]24\frac{379}{1000}[/tex]

Answer:

1/2

Step-by-step explanation:

The amplitude is 1/2.

The amplitude of the sin function is 1/2.

We have given the function

f(x) = 1/2sin(2x)

y(x,t)=Asin(kx−ωt+ϕ)

A is the amplitude of the wave.

ω is the wave's angular frequency.

k is the wavenumber

ϕ is the phase of the sine wave

Compare the given equation with the general formula of the sin wave.

Therefore we get,

y(x,t)=f(x)

A=1/2

Therefore the amplitude of the sin function is 1/2.
