Mathematics

Jlenok [28]3 years ago
3 0

Answer:

28 inches

Step-by-step explanation:

I think this is 28 inches because you add up all the sides 5+6+4+5+2 and then the missing side is equal to 6 so if you add everything up you should get 28 inches

H=17+x/6 solve for H step for step
marusya05 [52]

Answer: h -18 =14

Step-by-step explanation:

You need to plug in -18 into the equation. So h(-18)=17+(-18)/6

h(-18)=17-3

h(-18)=14

A consumer advocacy group tested the "on-air" lifetimes a random sample of 241 cell phone batteries. The mean lifetime was 3.2 h
snow_tiger [21]

Using the Empirical Rule, it is found that 229 batteries have lifetimes between 3.0 hours and 3.4 hours.

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

By the Empirical Rule, in a normal variable: 68% of the measures are within 1 standard deviation of the mean, 95% are within 2 and 99.7% are within 3.

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

  • Mean of 3.2 hours with a standard deviation of 0.2 hours.

3 = 3.2 - 2(0.1)

3.4 = 3.2 + 2(0.1)

  • Thus, between 3 and 3.4 hours is <u>within 2 standard deviations of the mean</u>, which is 95%.
  • Out of 241 batteries: 0.95(241) = 229

229 batteries have lifetimes between 3.0 hours and 3.4 hours.

Factoring trinomials,help?
borishaifa [10]
Hey there!

When factoring trinomials, we're usually looking at the trinomial in the format of:

ax^2 + bx + c

In order to factor these, we have to use a different method than when a<1. When a is less than one, we can simply figure out the factors that add to the middle term and multiply to the last, but here we have to do a little something different.

The first step is to factor out the GCD of these terms. As you can see, there isn't one, as 13 is prime.

The next step is to multiply a by c:

6(6) = 36

Next, we have to, using the pattern of trinomials(the two binomials would have factors that add to the middle term and multiply to the last), we have to find factors of 36 that multiply to 36 and add to -13. When we do this step, we can disregard the last term for now. Let's list factors of 36:

36 =
18, 2 = 20
9,4 = 13
-9, -4 = 13
 
 -9 and -4 work for this. We can now write them as x terms and factor by grouping:

6m^2 - 4m - 9m + 6   (don't forget that last term)

For the left side, factor out a 2m:

2m(3m - 2)

For the right side, factor out a -3:

2m(m-2) - 3(m-2)

Now that we have our common factor of m-2, we can write them as a product of 2 binomials:

(2m-3)(m-2)

Hope this helps!

Simplify square root of 1008 ( V` Represents the square root sign.)
Alexus [3.1K]
So first factor it
1008=2*2*2*2*3*3*7
group them in similar pairs
1008=(2*2)(2*2)(3*3)*7
now remember we can do
\sqrt{xy}= \sqrt{x} \sqrt{y} so
\sqrt{1008}= (\sqrt{2*2}) (\sqrt{2*2}) (\sqrt{3*3}) (\sqrt{7})=
2*2*3*\sqrt{7}=
12√7

the answer is B
