Answer:

4+2radical3

Step-by-step explanation:

Using the t-distribution, as we have the standard deviation for the sample, it is found that the the maximum error of estimate for the actual population mean for the height of Egyptian pyramids is of 47.01%.

The confidence interval is:

[tex]\overline{x} \pm t\frac{s}{\sqrt{n}}[/tex]

In which:

The margin of error is:

[tex]M = t\frac{s}{\sqrt{n}}[/tex]

The critical value, using a t-distribution calculator, for a two-tailed 80% confidence interval, with 125 - 1 = 124 df, is t = 1.2884.

The other parameters are: [tex]\mu = 460.7, s = 4.1, n = 125[/tex].

Hence, the margin of error is of:

[tex]M = t\frac{s}{\sqrt{n}}[/tex]

[tex]M = 1.2884\frac{4.1}{\sqrt{125}}[/tex]

[tex]M = 0.47[/tex]

Hence, the maximum error of estimate for the actual population mean for the height of Egyptian pyramids is of 47.01%.

Answer:

x = 5

Step-by-step explanation:

I just solved the equation!

5 - 4(2-x) = 17

-4(2-x) = 12 (subtract by 5 on both sides)

2 - x = -3 (divide by 4 on both sides)

-x = -5 (subtract by 2 on both sides)

x = 5 (divide by -1 on both sides (two negatives cancel out!))

:)

Answer:

x = 5

Step-by-step explanation:

1) Subtract 5 from both sides.

-4(2-x)=17-5

2) Simplify 17 - 5 to 12.

-4(2-x)=12

3) Divide both sides by -4.

2-x=-12/4

4) Simplify 12/4 to 3.

2-x=-3

5) Subtract 2 from both sides.

-x=-3-2

6) Simplify - 3 - 2 to -5.

-x=-5

7) Multiply both sides by -1.

x = 5

Check the answer:

5-4(2-x)=17

1) Let x=5.

5-4*(2-5)=17

2) Simplify 2-5 to 3.

5-4*-3=17

3) Simplify 4 * -3 to -12.

5-(-12)=17

4) Remove parentheses.

5+12=17

5) Simplify 5 + 12 to 17.

17 = 17

All done !

Answer:

I don't know if there are more answers for 2, but a is correct.

Answer:

65 + 12.5v = m (M being free movie)

Step-by-step explanation:

65 for the original 65 poitns he gets for signing up, then if he gets 12.5 points for every movie he visits then you need to multiply 12.5 times the amount of movies he went to (v) so it would be 65 + 12.5v
v would need to be 11.6

If you do 210 - 65 thats 145, then you do 145 divided by 12.5 which would get you 11.6

Answer:

Step-by-step explanation:

If two triangles are similar to each other, that means all their angle are equal, which means in this case that:

That means we get the equation:

3x = 24 --> x = 8

9y = 108 --> y= 12

z = 360 - 24 - 108 = 226

Thus x = 8, y = 12, and z = 226

Answer:

[tex]\sf c = -4[/tex]  and  [tex]\sf b = -6[/tex]

Explanation:

using the formula: [tex]\sf x = \frac{ -b \pm \sqrt{b^2 - 4ac}}{2a}[/tex]

Here the a = 1

using the equation:

[tex]3 \pm\sqrt{13}= \frac{ -b \pm \sqrt{b^2 - 4(1)c}}{2(1)}[/tex]

[tex]6 \pm2\sqrt{13}= -b \pm \sqrt{b^2 - 4(1)c}}[/tex]

matching the coefficients: b = - 6

find c:

[tex]6 \pm2\sqrt{13}= -(-6) \pm \sqrt{(-6)^2 - 4(1)c}}[/tex]

[tex]6 \pm2\sqrt{13}= 6 \pm \sqrt{36 - 4c}}[/tex]

[tex]\sf 6 \pm\sqrt{52}= 6 \pm \sqrt{36 - 4c}}[/tex]

[tex]\sf 36-4c = 52[/tex]

[tex]\sf -4c = 52-36[/tex]

[tex]\sf -4x = 16[/tex]

Answer:

x =62     y=118

Step-by-step explanation:

The sum of two opposite angles in a cyclic quadrilateral is equal to 180 degrees (supplementary angles)

x+44+74= 180

x+118=180

x=62

      y-48+110=180

     y+62=180

      y=118

Replace x with 7 and simplify to get 8+x = 8+7 = 15

Answer:

If x=7, 8+7=15.

Step-by-step explanation:

x=7

8+(7)

=15

say the regular price is "x", which is the 100% of the value, and we know it's discounted by 40%, so that means 100% - 40% = 60%, and we know as well that that value is 1200, so.

[tex]\begin{array}{ccll} amount&\%\\ \cline{1-2} x&100\\ 1200&60 \end{array}\implies \cfrac{x}{1200}=\cfrac{100}{60}\implies \cfrac{x}{1200}=\cfrac{5}{3} \\\\\\ 3x=6000\implies x=\cfrac{6000}{3}\implies x=2000[/tex]

Answer:

16 seconds

Step-by-step explanation:

So, we know that distance equals 100.

We also know that Dita covers 6.25 meters of this distance every second.

Since this is 6.25 PER second, we can write this as 6.25s, where s is seconds.

To find the seconds it takes to cover 100 meters in distance, we can write the following equation:

6.25s = 100

This makes sense, since the 100 meters in distance is equal to the rate of change in meters, times the seconds.

Now we just need to solve for s.

To do this, we must get s alone. We can do this by dividing 6.5 from both sides:

[tex]\frac{6.25}{6.25}s = \frac{100}{6.25}[/tex]  

     =

  s = 16

So this means the seconds it takes to go 100 meters is 16 seconds, your first answer option

Answer:

360 meters

Step-by-step explanation:

Hello!

Let's first convert 250 seconds to minutes.

Since 1 minute is 60 seconds:

The runner ran 1500 meters in 4 and 1/6 of a minute

Now we need to find the unit rate using this equation:    [tex]\frac{\text{x}}{\text{1 minute}} = \frac{1500}{4\frac{1}{6}}[/tex]

Cross multiply:

360 meters

Answer:

[tex]\displaystyle 360\:m./min.[/tex]

Step-by-step explanation:

When converting from a smaller unit to a bigger unit, use division, especially because you are converting from [tex]\displaystyle m/s[/tex]to [tex]\displaystyle m./min..[/tex]First, you divide 250 by 60 to get 4⅙ minutes. You will then divide 1500 by 4⅙ to get this:

[tex]\displaystyle 1500\:metres\:in\:4\frac{1}{6}\:minutes \\ \\ 360 = \frac{1500}{4\frac{1}{6}} \\ \\ \\ \boxed{360\:m./min.}[/tex]
