If 12 is 10% of the value what is that value

2 answers:

7 0

Any number that is 10% of another number is just saying it's been divided by 10. That means to work out the original number, you do the opposite. (multiply).

Therefore:
12 × 10 = 120.

The value is 120.

For this question you can say:
10/100 = 12/?
so ? is your value:
12*100/10 = 120 :)))
i hope this is helpful
have a nice day

The amount of lateral expansion (mils) was determined for a sample of n = 8 pulsed-power gas metal arc welds used in LNG ship co

Alona [7]

Answer:

95% Confidence interval for the variance:

$3.6511\leq \sigma^2\leq 34.5972$

95% Confidence interval for the standard deviation:

$1.9108\leq \sigma \leq 5.8819$

Step-by-step explanation:

We have to calculate a 95% confidence interval for the standard deviation σ and the variance σ².

The sample, of size n=8, has a standard deviation of s=2.89 miles.

Then, the variance of the sample is

$s^2=2.89^2=8.3521$

The confidence interval for the variance is:

$\dfrac{ (n - 1) s^2}{ \chi_{\alpha/2}^2} \leq \sigma^2 \leq \dfrac{ (n - 1) s^2}{\chi_{1-\alpha/2}^2}$

The critical values for the Chi-square distribution for a 95% confidence (α=0.05) interval are:

$\chi_{0.025}=1.6899\\\\\chi_{0.975}=16.0128$

Then, the confidence interval can be calculated as:

$\dfrac{ (8 - 1) 8.3521}{ 16.0128} \leq \sigma^2 \leq \dfrac{ (8 - 1) 8.3521}{1.6899}\\\\\\3.6511\leq \sigma^2\leq 34.5972$

If we calculate the square root for each bound we will have the confidence interval for the standard deviation:

$\sqrt{3.6511}\leq \sigma\leq \sqrt{34.5972}\\\\\\1.9108\leq \sigma \leq 5.8819$

Round off the number 5028.563 to the nearest thousand

konstantin123 [22]

Answer:

5000

Step-by-step explanation:

Because this is to the nearest THOUSAND, you know you are looking for numbers like 1000, 2000, etc. And you see that with 5028.563, it is below 5500, so you do not round up to 6000, so yoyu must round down to 5000.

What’s the answer For E

Vika [28.1K]

Answer:

∠E = 146°

Step-by-step explanation:

an isosceles triangle has both two equal sides and two equal angles
the sum of the interior angles of a triangle is 180°
the measure of third angle = the sum of the interior angles - the sum of two angles

E = 180 - (71 + 71) = 146

∠E = 146°
