What is the value of x if (13,84,x) is a Pythagorean triple?

Lena [83]

Answer:

x = 85

Step-by-step explanation:

Formula

a^2 + b^2 = c^2

Givens

a = 13
b = 84
c = x

Solution

13^2 + 84^2 = x^2 Substitute the givens into the formula
169 + 7056 = x^2 Add the left
7225 = x^2 Take the square root of both sides.
sqrt(7225) = sqrt(x^2)
x = 85

In an arithmetic sequence, T1=4 and T7=22.

jonny [76]

Answer:

Step-by-step explanation:

t1 means a1 and t7 means a7

a+(n-1)d=an

a+(1-1)d=4

so we get a as 4

a=4

a+(n-1)d=an

4+(7-1)d=22

4+6d=22

6d=22-4

d=18/6

d=3

QUESTION 2

aev [14]

The margin of error for a 95% confidence interval is 0.93.

mean (μ) = 23.4, standard deviation (σ) = 7.6, sample (n) = 254, confidence = 95% = 0.95

α = 1 - C = 1 - 0.95 = 0.05

α/2 = 0.05/2 = 0.025

The z score of α/2 is equal to the z score of 0.475 (0.5 - 0.025) which is equal to 1.96.

The margin of error (E) is given by:

$E=z_\frac{\alpha}{2} *\frac{\sigma}{\sqrt{n} } \\\\E=1.96*\frac{7.6}{\sqrt{254} } \\\\E=0.93$

The margin of error for a 95% confidence interval is 0.93.
