Answer:

Step-by-step explanation:

TO find the value for the terms, substitute n for the number in the sequence. so

for 1st term n = 1

for 2nd term n =2 etc.

1st Term = 1^2-3 = 1-3 = -2

2nd term = 2^2 - 3 = 4-3 = 1

3rd Term = 3^2 - 3 = 6

10th Term = 10^2 - 3 = 100 - 3 = 97

Mrs Smith is completing a mathematics problem. She knows when 6 is added to four times a number, the result is 50. What would be

Lesechka [4]

EXPLANATION:

-To formulate an equation, you must first know what data the exercise gives us to locate them correctly.

data:

-6 that must be added to a number.

-four times a number that is equal to 4x

-a result that is equal to 50

Now with these data we formulate the equation:

$\begin{gathered} \text{Equation:} \\ 6+4x=50;\text{ } \end{gathered}$

if we solve the equation we have:

$\begin{gathered} 6\text{ }+4x=50 \\ 4x=50-6 \\ 4x=44 \\ x=\frac{44}{4} \\ x=-\frac{22}{2} \\ x=\text{ }-11 \end{gathered}$

Suppose an advertising company wants to determine the current percentage of customers who read print magazines. How many custome

user100 [1]

Answer: 543

Step-by-step explanation:

Given : Level of confidence = 0.98

Significance level : $\alpha=1-0.98=0.02$

By using the normal distribution table,

Critical value : $z_{\alpha/2}=2.33$

Margin of error : $E=5\%=0.05$

The formula to find the population proportion if prior proportion of population is unknown :-

$n=0.25(\dfrac{z_{\alpha/2}}{E})^2$

$\Rightarrow n=0.25(\dfrac{2.33}{0.05})^2=542.89\approx543$

Hence, the company survey minimum sample having size =543
