Write 43 as a sum of powers of 2.<br> (2 Has to be the Base not the exponent)
slamgirl [31]

Answer:

2⁰ + 2¹+ 2⁵ +2³ = 43

Step-by-step explanation:

since 43 is odd, we know 2⁰ or 1 must be one of the sums

43 - 2⁰ = 42

42 - 2¹ = 40

16 = 2⁴

40-2(16) = 40 - 2⁵ = 8

8 = 2³

adding this all together

2⁰ + 2¹+ 2⁵ +2³ = 43

The mean annual income of certified welders is normally distributed with a mean of $50,000 and a population standard deviation o
Bogdan [553]

Using the p-value method, the decision rule is:

  • |z| < 1.645: do not reject the null hypothesis.
  • |z| > 1.645: reject the null hypothesis.

<h3>What is the relation between the p-value and the test hypothesis?</h3>

Depends on if the p-value is less or more than the significance level:

  • If it is more, the null hypothesis is not rejected.
  • If it is less, it is rejected.

In this problem, we have a two-tailed test, as we are testing if the mean is different of a value. For a significance level of 0.1, the critical value of z(when a p-value of 0.1 is obtained) is of |z| = 1.645, hence the decision rule is:

  • |z| < 1.645: do not reject the null hypothesis.
  • |z| > 1.645: reject the null hypothesis.
