Marya plans to participate in a 20 km walk-a-thon. To prepare, she walked 4 km on Monday. She plans to increase her walk by 2 km

each week until she reaches 20 km. Marya’s calculations: 4 + 2 = 6. 6 + 2 = 8. 8 + 2 = 10. 10 + 2 = 12. 12 + 2 = 14. 14 + 2 = 16. 16 + 2 = 18. 18 + 2 = 20. The equation representing Marya’s calculations is 4 + 2 w + 20. How many weeks will it take Marya to reach her goal of a 20 kilometer walk? 8 9 10 12

My name is Ann [436]

Answer:

(d) μ and σ²/n

Step-by-step explanation:

In a sampling distribution of sample means, the mean is equal to the population mean, which is μ.

The standard deviation of the sampling distribution of sample means is given by

σ/√n.

The variance of a distribution is the square of the standard deviation; this means the variance of the sampling distribution of sample means would be

(σ/√n)² = σ²/(√n)² = σ²/n

Social studies Geometry P.11 Similarity and altitudes in right triangles CEZ You have priz If SU = 28 and UV = 6, what is TU? T
Alex777 [14]

Answer:

TU ≈ 12.96

Step-by-step explanation:

Using the Altitude on Hypotenuse theorem

(leg of outer triangle)² = (part of hypotenuse below it) × (whole hypotenuse)

TU² = UV × SU = 6 × 28 = 168 ( take square root of both sides )

TU = \sqrt{168} ≈ 12.96 ( to the nearest hundredth )
