Answer:

x\in(1.146,\infty)

Step-by-step explanation:

We are given an inequality

e^x>14

We have to solve the given inequality.

Taking both side ln of given inequality

Then, we get

ln(e^x)>ln(14)

xlne>1.146

We know that

lne=1

Using the value

x>1.146

x\in(1.146,\infty)

Hence, the value of x is given by

x\in(1.146,\infty)

Fifty-six percent of Internet users have seen an online group come together to help a person or community solve a problem wherea
Lera25 [3.4K]

Answer:

95% confidence interval for the proportion of internet users who say online groups have helped solved a problem is between a lower limit of (0.65 - 0.9349/√n) and an upper limit of (0.65 + 0.9349/√n).

Step-by-step explanation:

Confidence interval for a proportion is given as p +/- margin of error (E)

p is the proportion of internet users who say online groups have helped solved a problem = 65% = 0.65

Let the number of internet users be represented by n

confidence level (C) = 95% = 0.95

significance level = 1 - C = 1 - 0.95 = 0.05 = 5%

critical value corresponding to infinity degrees of freedom and 5% significance level is 1.96

E = critical value × sqrt[p(1-p) ÷ n] = 1.96 × sqrt[0.65(1-0.65) ÷ n] = 1.96 × sqrt(0.2275 ÷ n) = 1.96×0.477/√n = 0.9349/√n

Lower limit of proportion = p - E = 0.65 - 0.9349/√n

Upper limit of proportion = p + E = 0.65 + 0.9349/√n

95% confidence interval is (0.65-0.9349/√n, 0.65+0.9349/√n)

What is the simplified value of the exponential expression 16 superscript one-fourth? 2 4
Ivahew [28]

For the exponential expression, 16^{1/4} the simplified value is 2.

<h3>How to simplify the exponential expression?</h3>

First, we need to remember a rule for exponential expressions, it says that:

x^{1/n} = \sqrt[n]{x}

Then we can rewrite the given exponential expression as:

16^{1/4} =\sqrt[4]{16}

So, we just need to find a number that when multiplied by itself 4 times, is equal to 16.

We know that:

2*2 = 4

Then:

2*2*2*2 = 2⁴ = 4*4 = 16

Then we can conclude that:

16^{1/4} =\sqrt[4]{16} = 2

So the simplified value of the exponential expression is 2.

kaheart [24]

Answer: \large\boxed{29}

Step-by-step explanation:

The sum of 10 consecutive integersstarting with 11

= 11 + 12 + 13 + 14 + 15 + 16 + 17 + 18 + 19 + 20 = 155

Lets try 29:

29 + 30 + 31 + 32 + 33 = 155

Therefore our answer is:

\large\boxed{29}
