The probability of 2 seniors out of 20 serving in the military is ²⁰C₂(0.15)²(0.85)¹⁸.

A common discrete distribution is used in statistics, as opposed to a continuous distribution is called a Binomial distribution. It is given by the formula,

[tex]P(x) = ^nC_x p^xq^{(n-x)}[/tex]

Where,

x is the number of successes needed,

n is the number of trials or sample size,

p is the probability of a single success, and

q is the probability of a single failure.

As it is given that 15% of the seniors in a large high school enter military

service upon graduation. Therefore, the probability of a large high school entering the military services will be 0.15. Similarly, the probability of a senior from a large high school not joining entering the military can be written as,

[tex]q = (1-p)\\\\q = 1-0.15\\\\q=0.85[/tex]

Now, the probability of 2 seniors out of 20 serving in the military will be,

[tex]P(x) = ^nC_x p^xq^{(n-x)}\\\\P(x=2) = ^{20}C_2 \times (0.15)^2 \times (0.85)^{(20-2)}\\\\P(x=2) = ^{20}C_2 \times (0.15)^2 \times (0.85)^{(18)}[/tex]

Hence, the probability of 2 seniors out of 20 serving in the military is ²⁰C₂(0.15)²(0.85)¹⁸.

Step-by-step explanation:

complementary angle is 90 degrees

so angle t and s are complementary

measure of angle t is 72 degrees

so measure of angle s will be 90 degrees minus 72 degrees which gives 18 degrees

so measure of angle s is 18 degrees

angle r and angle s are supplement which means their sum is 180 degrees

so measure of angle r will be 180 minus 18 which gives 162

so measure of angle r is 162 degrees

we need to find measure.of angle r minus measure.of angle s

so 162 minus 18 which gives 14r

Answer:

[tex]25=6t+4.5h[/tex]

2 pounds of ham

Step-by-step explanation:

1) Construct an equation

Let [tex]t[/tex] be equal to the number of pounds of turkey.

Let [tex]h[/tex] be equal to the number of pounds of ham.

We know that every pound of turkey costs 6 dollars, so the amount of money Lucy must spend on turkey is [tex]6t[/tex].

We also know that every pound of ham costs 4.50 dollars, so the amount of money Lucy must spend on ham is [tex]4.5h[/tex].

However, because 25 dollars is her budget, [tex]6t[/tex] and [tex]4.5h[/tex] must be equal to 25.

[tex]25=6t+4.5h[/tex]

2) How much ham can Lucy buy if she bought 2.5 pounds of turkey?

[tex]25=6t+4.5h[/tex]

Plug in 2.5 as [tex]t[/tex]

[tex]25=6(2.5)+4.5h\\25=15+4.5h[/tex]

Subtract both sides by 15

[tex]25-15=15+4.5h-15\\10=4.5h[/tex]

Divide both sides by 4.5

[tex]\frac{10}{4.5}=\frac{4.5h}{4.5} \\2.22=h[/tex]

Therefore, Lucy can buy 2 pounds of ham if she bought 2.5 pounds of turkey.

I hope this helps!

Answer:

6x + 4.5y ≤ 25

If Lucy bought 2.5 pounds of turkey, she can buy at most 2.22 pounds of ham.

Step-by-step explanation:

6(2.5) + 4.5y ≤ 25

15 + 4.5y ≤ 25

4.5y ≤ 10

y ≤ 2.22

Answer:

T = 162 minutes

Step-by-step explanation:

Given that,

Jill can run 5 miles in 45 minutes.

We need to find how long will it take her to run 18 miles.

[tex]5\ miles =45\ minutes\\\\1\ mile=(\dfrac{45}{5})\ minute\\\\1\ mile =9\ minute[/tex]

So,

18 miles = (18×9) minutes

= 162 minutes

Hence, 162 minutes will be taken by her to run 162 minutes.

Answer:

13.8 ounces of salt

Step-by-step explanation:

A restaurant small salt shakers contains 0.6 ounces of salt. The shakers are filled from a container that has 18.6 ounces of salt. If 8 shakers are filled, how much salt will be remaining in the salt container?

Step 1

Note that:

1 shaker = 0.6 ounces of salt

8 shakers = x

Cross Multiply

x = 8 × 0.6 ounces of salt

x = 4.8 ounces of salt

Step 2

The shakers are filled from a container that has 18.6 ounces of salt. If 8 shakers are filled, how much salt will be remaining in the salt container?

This is calculated as:

18.6 ounces of salt - 4.8 ounces of salt

= 13.8 ounces of salt

-x^5 + 7x⁴ + 8x² - 9x - 5

Step-by-step explanation:

For the question given:

Rocks traded, sold or given away are denoted by negative values, '-' while rocks bought or purchased are diniywd as positive, '+'

Starting = 8x² ;

Purchase = + 7x⁴ ;

Trades = - x^5

Gives away = - 9x

Sells = - 5

The number of rocks Emily now has :

8x² + 7x⁴ - x^5 - 9x - 5

In standard form:

Arrange in order of power :

-x^5 + 7x⁴ + 8x² - 9x - 5

Answer: A reflection about the y-axis and a clockwise rotation of 90° around the origin.

another example is:

A counterclockwise rotation of 90° around the origin, and then a reflection about the y-axis.

Step-by-step explanation:

Let's do this for a single point because it is essentially the same.

Let's use the point (3, -2)

First, we have a reflection across the x-axis, this only changes the sign of the y-component.

Then the new point will be: (3, -(-2)) = (3, 2)

Notice that this point is on the first quadrant.

Now we do a 90° counterclockwise rotation.

Then we move to the second quadrant, and we change the order of the components in the point (and because we are in the second quadrant, the x-component is negative and the y-component is positive)

Then the new point is (-2, 3)

Now, another transformation that is equivalent to this one is to do first a reflection about the y-axis, so we only change the sign of the y-component

Then the new point is (-3, -2)

And now we are in the third quadrant.

and then we do a rotation of 90° clockwise, which moves our point to the second quadrant, changes the order of the components and leaves the y-component positive and the x-component negative, then the new point is:

(-2, 3)

Same as before.

(notice that we used the same transformations, but applied to different line and direction of rotation)

Another example is if we first start with a counterclockwise rotation of 90° around the origin, the original point (3, -2) is on the fourth quadrant, so this rotation leaves our point in the first quadrant, so we change the order of the components and both of them will have a positive sign.

The new point is: (2, 3)

Now let's do a reflection about the y-axis, which changes the sign of the x-component.

Then the final point is (-2, 3), same as before.

And there are a lot of other transformations that will be equivalent to this ones, these are just two examples.

Using the equation y = abx , substitute both of your given points into that equation.

2 = ab2 and 4 = ab3 Solve each equation for a.

2⁄b2 and 4⁄b3 = a Therefore, 2⁄b2 = 4⁄b3

Cross multiply: 2b3 = 4b2 Divide both sides by b2

2b = 4 a = 2/4 = 1/2

b = 2

y = 1 (2)x

[tex]D) 0.5x^3y + 4x^2 y^2 - 2xy^3[/tex]

Step-by-step explanation:

Set up an equation to model the situation,

[tex](-0.5xy)(x^2 + 8xy - 4y^2)[/tex]

Distribute, multiply each term in the parenthesis with the term outside of the parenthesis. Don't forget the laws of exponents, when one multiplies two exponents, with the same base, then one adds the two exponents. A number with no exponential term is two the first degree meaning that it is to the power of one.

[tex]-0.5x^3 y - 4x^2 y^2 + 2xy^3[/tex]
