Answer: 12

Step-by-step explanation: Since 4 and 3 have no factors in common, the least common multiple comes from multiplying them together.

So we have 4 × 3 or 12.

Answer:

The Sample size is 1918.89035

Step-by-step explanation:

Consider the provided information.

It is given that 14 out of 105 samples failed.

Therefore p = 14/105 = 0.13 3... and q=1-0.133=0.867

Samples would be needed to create a 99 percent confidence interval.

Subtract the confidence level from 1, then divide by two.

$\frac{(1 -0.99)}{2}=0.005$

By standard normal table z=2.5758≈2.58

Calculate the sample size as:

$n=\frac{z^2pq}{e^2}$

Where, e is the margin of error,

Substitute the respective values.

$n=\frac{(2.58)^2(0.133)(0.867)}{(0.02)^2}=1918.89$

Hence, the Sample size is 1918.89035

Is this right ? Geometry

elixir [45]

No, 12 is the wrong answer. 5 is correct

This is because since a and c are congruent that means y=52. And we already know that every triangle adds up to 180 degrees so, you add A and C and get 104 (52+52).
And 180-104=76 so, 14x+6 must =76.
14(5)=70+6=76. 76+104=180, therefore, x=5.
