Your sister is 10. So your brother is 4. (Your sister is 6 years older than your brother.) You are 12. (Your brother is 1/3 your age)


So: (10 - 6) * 3 = your age = 12

A 95 percent confidence interval for the mean of a population is to be constructedand must be accurate within 0.3 unit. A prelim
jarptica [38.1K]

Answer:

B. 359

Step-by-step explanation:

Given that:

The margin of error (e) must be within 0.3 unit, The standard deviation (σ) = 2.9 and the the confidence level = 95% = 0.95

α = 1 =0.95 = 0.05

\frac{\alpha}{2}=\frac{0.05}{2}=0.025

The z score of 0.025 corresponds to the z score of 0.0475 (0.5 - 0.025) which can be gotten from the normal probability table.

Therefore: z_\frac{\alpha}{2}= z_{0.025}=1.96

The formula for the margin of error is given by:

e=z_{0.025}\frac{\sigma}{\sqrt{n} } \\Substituting:\\0.3=1.96*\frac{2.9}{\sqrt{n} } \\\sqrt{n}=\frac{1.96*2.9}{0.3}\\\sqrt{n} =18.95\\  n=18.95^2=359

Therefore the smallest sample size (n) is 359

Can someone help with these problem please?

The missing exponent is -3. The exponent on the x variable only applies to x, so with that in mind, only x is in the denominator. This means that its exponent needs to be a negative. A negative exponent flips its base to the reciprocal making x into 1/x. When multiplying only an exponent, you multiply the two exponents. For example: (y^4)^2 = y^8. 2 times 3 is 6.

The missing exponent is -3. A negative exponent flips the base to its reciprocal making 2x/3 into 3/2x, and 3^3 is 27. The same applies to 2x. (2x)^3 is 8x^3.

The other one’s missing exponent is 2. As, mention before, a negative exponent results in flipping the base to its reciprocal making 1/3 into 3. 3^3 is 27. You can figure out which exponent make 3 into 9 which is 2.
Hope this helped.
