<u>Given</u>:

The given inequality is 3u+3(u+1)>2u+7

We need to determine the solution of the inequality in interval notation.

<u>Solution of the inequality:</u>

The solution of the inequality can be determined by simplifying the inequality.

Thus, we have,

3u+3u+3>2u+7

       6u+3>2u+7

Subtracting both sides by 3, we get;

6 u>2 u+4

Subtracting both sides by 2u, we have;

4 u>4

Dividing both sides by 4, we get;

u>1

Writing it in interval notation, we get;

(1, \infty)

Thus, the solution of the inequality is (1, \infty)

True or false this number is written in scientific notation? <br> .2486 x 10^12
Scilla [17]

Answer:

<h2>It Is True </h2>

It is true because scientific notation is a way of writing very large or very small numbers. A number is written in scientific notation when a number between 1 and 10 is multiplied by a power of 10. For example, 650,000,000 can be written in scientific notation as 6.5 ✕ 10^8.

5(–9a–1)+7?<br> so<br> me<br> on<br> e <br> an<br> sw<br> er<br> pl<br> ea<br> se
il63 [147K]

Answer:

5(–9a–1)+7=0

5(-9a-1)=-7

-9a-1=-7/5

9a+1=7/5

9a=7/5 +1

a=(7+5)/(5×9)=35/45=7/9

Mashcka [7]

Answer:

Option a

Step-by-step explanation:

Given two normal distribution samples

I group has 106 as mean and 8.5 as std deviation with sample size = 60

II group has 121 as mean and 6.3 as std deviation with sample size =38

We find mean difference =-15

For margin of error finding, we have to find the combined std error for the difference

Variance of difference = Sum of variances

STd error for difference = 1.50

Hence for 99% margin of error =2.58(1.50)

= 3.87
