Answer:

The two numbers are 9 and 5.

Step-by-step explanation:

The question is:

The sum of two numbers is 14, adding 1 to the greatest gives twice the smallest which are the two numbers. if it can be explained please

Solution:

Denote the two numbers by <em>x</em> and <em>y</em>.

It is provided that:

x+y=14...(i)

Also,

x+1=2y\\\Rightarrow x-2y=-1...(ii)

Solve the equations (i) and (ii) by the substitution method as follows:

In equation (ii) substitute <em>x</em> = 14 - y and solve for <em>y</em>:

x-2y=-1\\14-y-2y=-1\\-3y=-1-14\\-3y=-15\\y=5

Substitute <em>y</em> in equation (i) and solve for <em>x</em> as follows:

x+y=14\\x+5=14\\x=14-5\\x=9

Thus, the two numbers are 9 and 5.

mezya [45]

Answer:

The answer is below

Step-by-step explanation:

Twenty-five blood samples were selected by taking every seventh blood sample from racks holding 187 blood samples from the morning draw at a medical center. The white blood count (WBC) was measured using a Coulter Counter Model S. The mean WBC was 8.636 with a standard deviation of 3.9265. (a) Construct a 90% confidence interval for the true mean using the FPCF. (Round your answers to 4 decimal places.) The 90% confidence interval is from to

Answer:

Given:

Mean (μ) = 8.636, standard deviation (σ) = 3.9265, Confidence (C) = 90% = 0.9, sample size (n) = 25

α = 1 - C = 1 - 0.9 = 0.1

α/2 = 0.1/2 = 0.05

From the normal distribution table, The z score of α/2 (0.05) corresponds to the z score of 0.45 (0.5 - 0.05) which is 1.645

The margin of error (E) is given by:

E=z_{\frac{\alpha}{2} }*\frac{\sigma}{\sqrt{n} }\\ \\E=1.645*\frac{3.9265}{\sqrt{25} }=1.2918

The confidence interval = μ ± E = 8.636 ± 1.2918 = (7.3442, 9.9278)

The 90% confidence interval is from 7.3442 to 9.9278
