Find the indicated probability. In one town, 71% of adults have health insurance. What is the probability that 4 adults selected at random from the town all have health insurance

Answers

Answer:

0.254

Step-by-step explanation:

Given that:

Percentage of those having health insurance = 71%

p = 71 / 100 = 0.71

Number of adults selected at random, n = 4

Probability that 4 selected have health insurance :

p^n = 0.71^4 = 0.25411681

= 0.254

Which expression is equivalent to 21^3sqrt15 - 9^3sqrt15?

A. 12
B. 30^3sqrt15
C. 12^3sqrt5
D. 12^3sqrt15

Answers

Answer:

the answer is D.

Step-by-step explanation:

Since the square: (3√15) is common in both of them, you only focus on 21 and 9. if you subtract 9 from 21, it will give you 12. so, just add (3√15) to 12, which will give you: 12^3sqrt15

Which graph represents this system? 2x-5v=-5 y=-3x+1​

Answers

Answer:

Please check the attached graph.

Step-by-step explanation:

The slope-intercept form of the line equation

[tex]y = mx+b[/tex]

where

m is the slopeb is the y-intercept

Given the system of equations

2x - 5y = -5    --- [Equation 1]

y = -3x + 1​      --- [Equation 2]

converting the equation 1 in the slope-intercept form

2x - 5y = -5

5y = 2x+5

divide both sides by 5

y = 2/5x + 1

Thus, the y-intercept  = 1

Now, please check the attached graph below.

The red line represents the equation  2x - 5y = -5

From the graph, it is clear that the red line has the y-intercept y = 1.

Now, considerng the equation 2

y = -3x + 1​  

comparing with the slope-intercept form of line equation

The y-intercept b = 1

Hence, the y-intercept of the line y = -3x + 1​ is y = 1

The green line represents the equation  y = -3x + 1​  

From the graph, it is clear that the green line has the y-intercept y = 1.

Point of Intersection:

It is clear from the graph:

The red line represents the equation  2x - 5y = -5.The green line represents the equation  y = -3x + 1​.

As both lines meet or intersect at the point (0, 1).

Therefore, the point of intersection of both the lines is:

(x, y) = (0, 1)

As we know that the point of intersection of both the lines represents the solution to the system of equations.

Therefore, (0, 1) on the graph represents the solution to the system of equations.

The graph is attached below.

please help and can someone explain what a integer is

Answers

w = -18

x = -10

y = -2

z = 10

x and z are opposite, x= -10, where as z = 10, Hence x times (-1) equals z.

An integer is a non-fractional number real number. It can be either negative or positive, it simply cannot be a fraction.

"w", "x", and "y" are negative, and hence less than zero.

Find the length of dm in the given fig.​

Answers

Answer:

[tex]DM=12[/tex]

Step-by-step explanation:

(Let the point where the altitude from [tex]D[/tex] intersects [tex]AB[/tex] be called as point [tex]E[/tex].) First, let's find the area of parallelogram [tex]ABCD[/tex]. The area of a parallelogram is simply [tex]b*h=bh[/tex], where [tex]b[/tex] is the parallelogram's base and [tex]h[/tex] is the parallelogram's height. If we let [tex]AB[/tex] and [tex]DE[/tex] be the base and height respectively, since we are already given their lengths, we know that the area of parallelogram [tex]ABCD[/tex] will be [tex]AB*DE=15*8=120[/tex].

Now, how does this information matter, you might ask? Well, we can take either [tex]AB[/tex] or [tex]CB[/tex] to be the base and either [tex]DE[/tex] or [tex]DM[/tex] to be the height. In this case, let's take the latter two options, as we are looking to find the length of [tex]DM[/tex].

Therefore, we know that the area of parallelogram [tex]ABCD[/tex] can also be found by calculating [tex]CB*DM[/tex]. Since we know the values of the area and [tex]CB[/tex], we can write the following equation to solve for [tex]DM[/tex]:

[tex]Area = CB*DM[/tex]

[tex]120=10*DM[/tex] (Substitute [tex]Area=120[/tex] and [tex]CB=10[/tex] into the equation)

[tex]\frac{120}{10}=\frac{10*DM}{10}[/tex] (Divide both sides of the equation by [tex]10[/tex] to get rid of [tex]DM[/tex]'s coefficient)

[tex]12=DM[/tex] (Simplify)

[tex]DM=12[/tex] (Symmetric Property of Equality)

Meg is packing a shipping conditier.

There is one section of the shipping container that has not yet been packed. The space available is in the shape of rectangular

prism that measures 2 feet by 3 feet by 33 feet.

She will pack as many boxes into the available space as possible. Each box is in the shape of a cube with side length 1 foot.

The space available in the shinning container and one of the boxes are shown below.

Answers

Answer:

[tex]Boxes= 198[/tex]

Step-by-step explanation:

This question has uncleared details towards the end. However, one can deduce that we need to calculate the amount of box the available space can contain.

We have the following given parameters.

Shipping Container

[tex]Dimension: 2ft\ by\ 3ft\ by\ 33ft[/tex]

The box

[tex]Dimension: 1ft\ by\ 1ft\ by\ 1ft[/tex]

First, we calculate the volume of the shipping container.

[tex]V_A = 2ft * 3ft * 33ft[/tex]

[tex]V_A = 198ft^3[/tex]

Next, we calculate the volume of the box.

[tex]V_B = 1ft * 1ft * 1ft[/tex]

[tex]V_B = 1ft^3[/tex]

The number of box is then calculated as:

[tex]Boxes= \frac{V_A}{V_B}[/tex]

[tex]Boxes= \frac{198ft^3}{1ft^3}[/tex]

[tex]Boxes= \frac{198}{1}[/tex]

[tex]Boxes= 198[/tex]

Hence:

198 boxes will occupy the empty space

Michelle is hosting a party that starts at 6:00 PM. She realizes she did not freeze the ice cubes! She puts ice cubes in the freezer at 1:00 PM hoping they freeze by the time the party starts. The water is 82 degrees Fahrenheit when put into the freezer and will freeze when it reaches 32 degrees Fahrenheit. In Michelle's freezer the water cools to 80% of the temperature from the previous hour. Will the ice cubes freeze before the party starts?
