Answer:

7x + 6 = - 48

Step-by-step explanation:

Given

$\frac{7}{8}$ x + $\frac{3}{4}$ = - 6

Multiply through by 8 ( the LCM of 8 and 4 ) to clear the fractions

7x + 6 = - 48 ← same equation without fractions

If T(n) = 2n - 7 what is the 5th term

nadezda [96]

Plug in n = 5 to find the 5th term

T(5) = 2(5) - 7
T(5) = 10 - 7
T(5) = 3

The 5th term is 3.

The z-score associated with 95% is 1.96. If the sample mean is 200 and the standard deviation is 30, find the upper limit of the

ziro4ka [17]

Answer:

The upper limit of the 95% confidence interval is:

C.I_u = 200 + (58.8/ $\sqrt{n}$ )

Step-by-step explanation:

The formula is given as:

C.I = μ ± Z*σ/ $\sqrt{n}$

The upper limit => C.I_u = μ + Z*σ/ $\sqrt{n}$

The lower limit => C.I_l = μ - Z*σ/ $\sqrt{n}$

The sample size (n) is not stated in the question. Hence, we calculate the upper limit with respect to n.

The upper limit => C.I_u = 200 + 1.96*(30/ $\sqrt{n}$ )

= 200 + (1.96*30)/ $\sqrt{n}$

= 200 + 58.8/ $\sqrt{n}$
