Answer:The last option

Step-by-step explanation:the absolute value bars make it positive but the negative on the outside of those bars make it negative, this -|3|=-3 and -|2|=-2. Furthermore, the double negative on the last two dots make a positive, thus -(-2)=2 and -(-3)=3. With this in mind it is -3,-2,2,3 and -|3|,-|2|,-(-2),-(-3)

Answer:

± 1.13432%

between 23.966% and 26.234% households in the population who tuned into the final episode of ​"When Will it End question mark​"

Step-by-step explanation:

Given that:

Sample size (n). = 5613

Proportion (p) = 25.1% = 0.251

Margin of Error can be obtained using :

MOE = z * √p * (1 - p) / √n

Zscore at 95% confidence interval = 1.96

1 - p = 1 - 0.251 = 0.749

Hence,

Margin of Error :

1.96 * √0.251 * 0.749 / √5613

1.96 * (0.4335885 / 74.919957)

= 0.0113432

= ± (0.0113432) * 100%

= ± 1.13432%

B.) between (25.1 - 1.134)% = 23.966% and 25.1 + 1.134)% = 26.234% households in the population who tuned into the final episode of ​"When Will it End question mark​"

Margin of Error (MOE) is a function of the critical value. We will choose a confidential interval of 95 %.

Solution is:

a) MOE = 0,011

b) We can affirm with 95 % of confidence that the porcentage of TV households in the population watching th final  episode of " When ...

would be between  25,1 - 0,011  and  25,1 + 0,011

In our question we got:

Sample size    n = 5613

p = 25.1 %    ( positive events expressed as porcentage )

q = 1 - p     q = 1 - 0,251    q = 0,749

According to the size of the sample, and the fact that

q×n    and   p×n   are both    q×n > 10   p×n > 10

We are in condition to apply the approximation of the binomial distribution to normal distribution and use table z scores

CI   = 95 %    then  confidence level   α = 5 %    α/2 = 0,025  and fom z-table we get the critical value

z(c) = 1,96

Now to find MOE

MOE = z(c)×√(p×q/n)  ⇒ MOE = 1,96 × √ ( 0,251×0,749)5613

MOE = 1,96 × 0,005787

MOE = 0,011

Answer:

Yes

Step-by-step explanation: because it goes through the origin and its linear(it is straight)

Answer:  0.6 miles per minute

Note: this is equivalent to 36 miles per hour

===================================================

Explanation:

Imagine that we had a rubber tire and we cut out a section of it. This piece is an arc of the full circle (the original uncut tire). Laying the curved cut rubber piece out flat produces a straight line. If a point moves along this line, then it also moves along the piece of the circle.

To find the linear speed, we just need to divide the arc length over the time value.

In our case, we will compute the following:

linear speed = (arc length)/(time elapsed)

linear speed = (7.524 miles)/(12 minutes)

linear speed = (7.524/12) miles per minute

linear speed = 0.627 miles per minute

linear speed = 0.6 miles per minute

--------------------------

If needed, multiply that by 60 to convert to miles per hour

So we'd say:

(0.6 miles/min)*(60 min/1 hr) = 36 miles per hour

I wasn't sure which units your teacher wanted, so I figured why not show both.

The linear speed of a point that moves with a constant speed in a circular motion is, 0.6 miles per minutes.

Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications. For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.

Given that;

The point travels along a circle of arc length 7.524 miles in 12 minutes.

Now, We know that;

⇒ Linear speed = Arc length / Time

Substitute all the values, we get;

⇒ Linear speed = Arc length / Time

⇒ Linear speed = 7.524 / 12

⇒ Linear speed = 0.62 miles per minutes

Answer:

This application is frequently used in architecture, woodworking, or other physical construction projects. For instance, say you are building a sloped roof. If you know the height of the roof and the length for it to cover, you can use the Pythagorean Theorem to find the diagonal length of the roof's slope.

Answer:

Architecture, Engineering, Astronomy, etc.

Step-by-step explanation:

Engineers use the Pythagorean Theorem by knowing the height of the roof and the length for it to cover, and it will result in the diagonal length of the roof's slope.  Architects use the Pythagorean Theorem to calculate the heights of buildings and the lengths of walls. Astronomers sometimes use the theorem to calculate the paths of spacecraft, including rockets and satellites.

hypontenuse = 8.6 units

Step-by-step explanation:

Let the hypontenuse be x .

According to Pythagoras Theorem ,

=> base² + perpendicular ²= hypontenuse ²

=> h² = 5² + 7²

=> h² = 25 + 49

=> h² = 74

=> h = 8.6

Answer:

Step-by-step explanation:

So first it wants you to solve working backwards. This basically means to add up what you used and spilled, opposite of subtracting or using it. I will show that below.

a - You have 1.5 cans left. You painted 4 rooms, each needing 2 cans, making it 8 cans. Now you bought 9.5 cans. Then .5 of a can got spilled. So you bought 10 cans of paint.

Next is solving the equation. I'll explain below.

b - So simplify the equation, which will get x = 2.5. x represents the amount of paint used to paint each room. To represent the 4 rooms, multiply both sides by 4.

4x = 10. So, both b and a have the same answer, 10.

Answer:

n=0

Step-by-step explanation:

Let's solve your equation step-by-step.

3(−10n+9)−3(1+8n)=24

Step 1: Simplify both sides of the equation.

3(−10n+9)−3(1+8n)=24

(3)(−10n)+(3)(9)+(−3)(1)+(−3)(8n)=24(Distribute)

−30n+27+−3+−24n=24

(−30n+−24n)+(27+−3)=24(Combine Like Terms)

−54n+24=24

−54n+24=24

Step 2: Subtract 24 from both sides.

−54n+24−24=24−24

−54n=0

Step 3: Divide both sides by -54.

−54n/-54=0/−54
